Unable to obtain Server Assigned IP address - 8125, K-JAM, P4300, MDA Vario General

I recently returned from abroad when I connected to the LAN at the hotel I was staying in. However, after coming back I have been unable to connect to my office LAN through my laptop using the USB or WiFi. I can activesync, and the network connections show that I am connected. However, the IP address is not one that is recognised on the office system, which is why I believe I’m getting this strange error. I have server assigned IP address ticked and the address is assigned by the DCHP.
When I try to connect via the WiFi, the automatic IP address is off the wall with letter and numbers in the address; usually it should be only sequence of numbers. I have tried soft re-setting several times but to no avail.
Can anyone help, easy instructions please. I have only had the unit for a couple of months and am nervous of in depth tweaks and hacks.
Sorry if this should be in the general networking section. I posted here cause I thought it may be a wizard specific problem

XDAIIi wi-fi problem

Hi all. I looked at several wi-fi posts on here, but couldn't find anything related to my problem.
I'm beginning to suspect that it's because of something stupid I'm doing, cos it really should be working...
Anyhoo ...I have a wireless router at home, and it's serving 3 PCs with DHCP IP addresses, and an internet connection. I have no issues with it.
What I'm trying to do now is get my shiny new XDAIIi to connect, so that I can have the damn thing on the internet. So far, no luck.
Now, I have got the XDA to detect my SSID. It detects all the settings, and tells me it's connected. I even have a signal strength bar on it which reads about 50%.
However, when I set it to pick up a DHCP address it stubbornly refuses, remaining with a "I can't see a DHCP server" 169.x.x.x address.
I've tried reserving an address on the router and allocating it to the MAC address of the XDA, and manually setting the XDA to have that IP address, entering my router as the gateway, and even entering 2 valid DNS server IPs from my ISP into the name server entries. Still nothing. It says it's connected with the IP address I allocated, but I have no net connection, and I can't ping that address from any of my PCs.
All the while the status screen on the router tells me that the device, with it's MAC address, is connected to the router fine.
Surely this has to be something simple. I have set up all the clients and router for my network, and the settings on the XDA are pertty much the same, and really SHOULD be working.
I'm kinda at my wits end.
So basically any suggestions or advice, or anyone with similar experiences please get in touch, cos I'm struggling to see what I've done wrong, and it's giving me an ulcer.
Many thanks in advance.

3COM WAP (3CRWE454G72) - XDA IIi WIFI Problems
Hi Jess,
I very much share your frustration.
I have a 3COM WAP (3CRWE454G72) which has served me well. I have a few machines at home working from it. At work we have 20+ machines working from the same model (older firmware).
My specs are as follow:
3C number 3CRWE454G72
Software version 1.03.07A
Boot loader version 1.00.00
Wireless version V1.0.2.1
Hardware version R01A
Don't have the office one's specs here at the moment ...
At work I can get an IP address (there's a windows DHCP server) .. AND I can ping google and traceroute to google. BUT, XDA IIi doesn't seem "know" that it's connected (e.g. network settings shows the WAP as available, but not connected). SKYPE even works!! But nothing else, no IE, no Terminal Services Client, no Avant Go, no network ActiveSync. They all say that the is no network card configured (but with vxUTIL, vxIPCONFIG, etc). I can see ALL the IP details from the DHCP server.
At home it's worse. I can't even get it to connect to the WAP (either with WEP 128, WEP 64 or encryption turned off). As I'm not even getting an IP address at home from the WAP's DHCP server, I've built a new DHCP server on my one linux box and it works for all my machines ... now I can actually trace requests from devices for IP's ... and the XDA IIi never requests an IP address. Which tells me that it's not even getting through the first stages of connecting with the WAP (again tried WEP, NO WEP).
To make things worse. I have been able to connect to some open WAP's in the neighbourhood ... everything functioning normal.
I'm losing the will to live here also ... ;-)
Wolfie
the plot thickens...
Hi Wolfie.
Well, at this end I seem to have more news.
By removing all WEP encryption and removing the MAC address access restriction I had enabled, I got the XDAIIi online, and all was working.
I then enabled the security a step at a time, and at each step updated the configuration on the handheld, and it still all worked. I was so pleased.
)
However this morning I have come to put the thing online again, and once again it refuses to pick up a DHCP address.
I tried my process again, and this time it wont work.
It definitely seems that it's the encryption that's stopping it, but I can't get it working this morning.
When I disabled everything I managed to get it online, but then re-enabling the security killed it and I can't get it to come online again.
SIGH
Oh well, I will try again later. Fussy thing. Anyone ever manage to solve this ??
Jess
have u tried soft reseting the device and retrying, sometimes that cures these hiccups

WIFI WOES
Jess, thanks for the reply. There's hope. ;-)
I have tried your approach yesterday. However, to no avail. At home I completely opened my WAP, e.g. any MAC, no WEP/WPA, etc. But still nothing. When I look at my log files on the WAP. I can see plenty of entries coming from my XDA IIi ...
04 min(s) 41 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 43 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 45 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 46 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 48 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 50 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
... and it just goes on and on and on .... while trying to connect.
At the same time in all connections attemps, I don't get a single entry in my DHCP servers log saying that my XDA II attempted to connect.
Jim: I've tried hard resets, soft resets, O2 Active installed, Corporate mode, pretty much everything my single brain-cell can come up with. ;-)
The thing is definitely a little fiddly indeed ...
The search goes on ...
... anybody out there got their XDA IIi working with WIFI using DHCP and WEP or WPA?
Did you ever get this working?
I have a shiny new XDAIIi and have been trying to get connected via my Cisco Aironet 1200 WAP. The device happily detects my network, accepts the WEP key fine (complains if I enter the wrong key so I know it's communicating) but refuses to pick up an IP address. The Wireless LAN Manager just sits there "Scanning network..."
I firmly belive I'm just missing something but...........
Any help gratefully received :?

I got my QTek 2020i today and for the life of me I can't get it to connect to the internet using my wifi connection @ home
I also have a 3COM router 3CRWE754G72-A and I have my home pc connected to this and also occassionally my work PC - both with no probs.
I can get the qtek to connect and I get a 50% signal strength and I can view an IP address and everything looks good but I can't seem to setup a "Connection" as required by IE?
This is what I get:
"Cannot connect with current connection settings. To change your connection settings, tap Settins"
I tap settings and I get this:
My ISP
Add a new modem connection
My ISP
Add a new modem connection
Add a new VPN server connection
Set up my proxy server
I've gone into each of these and had a "play" but I still can't get the bloody thing to work :evil:
Can someone PLEASE help as this is starting to drive me mad! - I'm not giving up easily...I've been trying to get this to work for a good 4 hours now and I can't find anything in the manual or on the web that helps...this post was the closest I could fine >>> hence the bump!

have you try to configure the network cards in the connection setting and set the internet using the tiacxwln Compatible Wireless Ethernet?

Okay, I can get the connection to read "connected" via the Wireless Lan Manager and I can get an IP address - which is totally different to all the other PC's that use my wifi connection - they're all 192.168.1.x whereas this is very different? - the address that I get isn't even the same as the IP Address of my router - I have a static IP address so I know this isn't changing???
Also, when I view the network card page I see the following:
Configure Wireless Networks
Add New...
3Com Available
I can click on this and view the settings for it or I can hold-click and get the option of connecting. If I do this, it just says "connecting"; it never actually says "connected"?
Anyone know where I can get a walkthrough for this?

3 Com Routers
Hi, DotN
I put a 3Com router in my local pub.
I have no problem connecting to it and solving the usual pub talk problems with it.
If you are getting a connection but your IP address starts with 169.254 then I would say you have a WEP problem. The software only appears to check for incorrectly formatted WEP keys, so either turn it off or make sure you enter the correct key. When selecting connect to a router the message sticks on connecting, come out of the screen and go back in after about 30 secs. Check you ip address. I have had some issues with GRPS trying to connect, but they seem to go away after a couple of hides.
I have to say that I am not over the moon with my XDA2i, but the wifi part has worked pretty well for me.

Hi Paddy
Thanks for the info. You're bang on with the IP Address!...169.254.x.x
So what encryption can I use?
I've deffinately got the correct password but it's obviously not working
Cheers
Wayne
Hi again
Okay, I've just checked the encryption and I'm using WPA-PSK authentication with TKIP encryption.
Is this what you had?
Cheers

3 Com Routers
Are you using a password or 13 Hex pairs, I use the pairs. Try either turning wep of completely or entering 26 1s. Remove your setting for your ap in Configure Wireless Networks screen then reconnect.
Let me know what happens

Okay, I've basically removed all security from my wifi setup. I live in the middle of nowhere so it's not a problem - although once I get the wifi working I'll try and get the security going again.
I still can't get a connection
...stop the press!
Okay, I had a thought...maybe I can't connect because of the speed?
the router is a 11g but supports 11b (which is what the QTek 2020i/XDA IIuses) - sure enough, I had the 11g only option selected - DOH!
removed that and I've managed to connect without security.
I assume this was my problem all along...will now stick the security back on and try again
Thanks again Paddy
Cheers
Wayne
Update: I've now managed to get the wifi working with WPA-SPK authentication using TKIP encryption
all along it was simply a case of me having the speed on the router set above what the PDA was capable of! I'd set this ages ago when I first setup my wlan and had forgotten about it cause everything I use is 11g

Doh!...nope, not working again...back to the 169.254.x.x problem.
It's obviously to do with the encryption this time. I'll try some other variations - at least I know that it can work :roll:

Wayne
Ouch......
No hard feeling, glad you found the problem
Paddy
bump!
pretty much same prob!
i can get an ip, have to check what it is, it tells me its connected on the scanning network page but on the other bit it tells me its available or connecting but never connects!
i've turned wep off and still no joy!
its really starting to drive me mad!
please please someone help
Take a read back through the last lot of posts between myself and MacPad - I think you'll find the answer there.
For me, I had to totally disable my security and everything else - I could then connect. Once I'd done that, I managed to use WEP with a 26 digit key - start by using something like "0" 26 times...make sure u count as u type them zero's in though as if u get it wrong it won't work!
apart from that, not sure what to say. If you're getting the 164.x.x.x ip address though then as MacPad said, it's to do with the security.
I would mention that the XDAIIi/Qtek 2020ii use 11mbps wifi (b) and not 54mbps (g) so make sure u've got ya router configured to allow both types of connection...this eventually turned out to be my main problem - doh!
Cheers
Wayne
ok now im home ive re-read and done the things mentioned. with a completely unsecure connection i can get a connecation, but the moment i use any kind of encryption (im using wep 64bit, but tried 128bit as well) no matter what key i use i get a split second of connection then its gone!
firewall is not on either.
any ideas??
thank for the suggestions guys im finally progressing

Unable to stay connected to VPN server via Wifi

I am not able to stay connected to Windows 2003 pptp vpn server.
When i look at the logs on the server, it indicates the pda2k authenticated, ip address assigned, then it immediately disconnects, no errors on the server and no errors on the devie either......this is puzzling.
any ideas?
thanks.
I have exactly the same problem. I can see the connection is established on the PC but it drops after about 3 seconds. Really bugging me now.
Iain
found any solution to this problem yet??
8)
believe it effectively relates to the differences in the pocket pc using "internet" and "work" when choosing and establishing a connection type. internet expects "." in its addresses, whereas work doesnt and anticipates the use of Named addresses such as the name of your server, however, I dont find the DNS effective for this.
to allow it to work when the VPN is on a work connection, I think you need to use the exceptions tab, and insert the IP addresses you are using to connect as an exception to the rules, thus allowing 10.0.0.1 as an address if this the address to your server.
There are posts on this forum that are more specific, but this is the gist of it, search WIFI VPN or similar. Same method if using a VPN over GPRS.
I can connect after a softreset...it maybe work 1-10 times in a row...and then it just stops and dont work again...not until I do a softreset again!
I can go up on gprs and such and surf the net just fine...but not onto vpn.

Wireless Problem

Done a search on various site but still no joy.
Just got a o2 XDA Mini S yesterday.But I cannot get it to connect to my wireless network at home.Its an open network, with a laptop,3 PC's,2 xbox's accessing it various times of day.All connect no problem.
My xda says my network is available,but cannot connect to it. Do I need to put in IP addresses in manually ? On the network cards section, it the SDIO WLAN wireless adapter that is used ?
Have tried allsorts,
First Question,
Is your WiFi router set to DHCP mode. If so then check that your device is also set to DHCP mode. If not change router to DHCP check that all your other devices are set to DHCP then you should automatically be allocated an IP address. A useful utility is WiFi Companion.
This scans for available networks and allows you to connect. it will also show you the IP address you have been assigned.
You could assign an IP address manually but this will have to be changed every time you walk on to another network. DHCP is better.
Regrads
Thanks for the info DW, it is my router,popped round a mates last night and it connected to his network ok.
Will check what you said and the firewall
not sure by what you mean exactly by open network.
but are you using MAC address filtering?
when I got the Sony Laptop, I was so eager to get it all setup etc, that I forgot bout the filtering, it would see the network, but refused to connect.
I'm having the same problem. My Exec can see the network but not connect. I investigated it a bit more and for some reason it keeps trying to use the same IP address as my laptop. It also cannot connect to the net to update Avant Go when it's syncing (via my laptop).
I've tried connecting with all other devices switched off, to avoid the IP address conflict, but still cannot connect to the internet.
I'm pretty much stumped.
Setting the Wireless power setting for best performance was the trump for me.
On my Vario - Settings - Connections - Wireless LAN - Power Mode
Thanks for the suggestion. I gave it a try but unfortunately it didn't help.
If my laptop is switched off my Exec can connect to my D-Link router, but I cannot access any internet resources. I presume that somewhere in the settings is the solution but I can't find it.
EXCELLENT db44!!!
For some reasons setting wireless "best performance" wortked for me too. Wizard (QTEK 9100 - gray market I guess as QTEK did not register on their site for me). I will still try Opera too.
Kind regards,
Oleg.
www.nano-science.com
same thing happened to my qtek. it detected the network but could not connect and sometimes when it got connected, i still couldn't surf the net. is there anything in the settings that i'm missing? i also tried to enter the IP address manually but no luck either.
My O2 XDA Mini arrived yesterday. It sees my wireless network (as well as two others in my neighborhood) but cannot/will not connect. I've tried everything I've read above - which confirms I'm on the right trail, but...
The D-Link DI-624 wireless router is in DCHP mode. I've dropped all security for connection trials. I've put the MAC address of the XDA in the router, just in case. I cannot find the IP address of the Mini (how do you do that?), but have tried with and without allowing the router to assign it a random and an assigned IP address. My router does NOT have the default (198.162, etc, etc IP address.) so I've been careful not to blindly follow standard instructions. Of course, I have tried with specific IP addresses, default gateway (router), etc, etc.
One clue is that after trying for a long time to connect to the networks it finds, I got one error message from the XDA saying it could not be assigned an IP address from the network(s). Good clue - wish I know what it means.
There are only limited settings to check on the XDA, so I'm wondering if I'm missing something on the router. Any ideas? Many thanks.

ICS & VPN with WM6

My searches on the web haven't yielded much help or information so I thought I would come to the experts...
I have a Treo 750 that I just "upgraded" to WM6 2 days ago. I noticed that DUN has gone away and was replaced by ICS. After configuring my laptop to use that instead of DUN I connected and was surfing the web. My problem now is VPN. I travel frequently (luckily I'm in the office until Jan.) and regularly used my phone to connect to the corporate network via VPN. I also work with a lot of other companies and have VPN access to their systems as well. Basically now I can open my Cisco VPN client, connect to a VPN gateway, authenticate, get assigned all the appropriate IP information, but cannot communicate on the network. What gives? Is there a solution to this? If not, what the heck was MS thinking when they did this!? My phone is basically useless for one of the major reasons I bought it...
Any help is appreciated!
thanks!
Ok, further searches found that DUN can be added back into WM6 via a cab that was posted here at the XDA forums. I installed it and the DUN service is now visible again. I unpaired by phone and laptop, re-paired, and included DUN. Now when I try to connect, I get the DUN connection box after the bluetooth connection is initiated but when I click DIAL I get the DIALING... prompt, followed by Error 678: The remote computer did not respond.
Anybody get this working on a Treo 750? Thoughts, ideas suggestions?
What is the ip address you are getting via the cisco vpn client
It maybe that it is in the same subnet as the ip address assigned to the pc from the wm6 ics. The ICS gives the address 192.168.0.1. and if your Cisco is also giving a 192.168 address then you will have two routes for the 192 address range thus giving you the problem when accessing hosts.
If this is the problem Im pretty sure you can change the address allocated via the ICS using a registry editor. If not you may be able to get work to use a different range for you on the cisco vpn.
Our corporate network is 172.x.x.x so it's nowhere near the 192.168.0.x assigned by the phone. When I look at the route in the VPN client I see 192.0.0.0, 10.0.0.0, and 172.0.0.0 so I am assuming 192 is my laptop, 10 is the phone, and 172 is the corporate network.
I'm guessing NATing is the problem. I've been reading that if I use a different APN (isp.cingular instead of wap.cingular) there is no NATing. I've tried both, and I've tried turning off and on the "force AT&T" proxy setting to no avail.
Tried the DUN cab hack that is floating around for WM6 also. The service is active again and I can also add Modem Link back in and my laptop sees my Treo as a modem but when I dial I get an error stating the remote computer did not respond. I'm guessing along with going from WM5 to WM6 AT&T also updated the radio so the old communications protocols don't work anymore?
Hello Sir,
I have exactly the same problem... I have successfully connected via VPN, however unable to communicate with any devices on that network... Then what is the use of VPN on the phone? I've tried searching online for answers, but no luck... People are having the same problem but no one knows how to solve it... I'll try and trouble shoot this problem more as soon as my exams are done...
Hi
Working successfully for me. I am using Imate jasjam wm6. Pc using cisco client connecting via ics on phone. I have telstra 3g connection tested ok on both telstra.internet (Nated ip) and telstra.extranet (real ip).
You are correct it may be an nat issue. Can you check that your transparent tunnelling is on as follows: right click on your connection entry in cisco client and select modify then transport tab. Check that enable transport tunneling is enabled ipsec over udp(Nat/pat).
The other thing to check is that the cisco vpn server aslo has transport over Nat on as well.
Also are you sure your corporate ip range is 172 or is that the range given by the cisco vpn to clients.
Transport tunneling is on (always was). I'll have to check with our network admin and check on the VPN server setting...I guess as long as I have connectivity back to the office, I don't need it that badly for all the customers I need to connect to at various times.
Yep, positive on the corporate IP. Right now it is 172.28.1.87 and I'm in the office.
Thanks for the help so far. Got any other suggestions on how I can troubleshoot further?
One other thought...should I modify the registry on the phone to assign a different IP address to my laptop? Would that help?
Same Problem
MX. I am having the exact same issue but with Securemote VPN. I've looked through the registry and found the assigned address, but I'm wary of changing anything until I can find some more information.
Anyone out there ever change the DHCP configuration for their phone?
Somewhat related question?
Im attempting to route my connection on my mobile through a laptop acting as a wan bridge, then uplinking it into the router. The issue Im having is that XP and WM6 both use the same IP Block. Ive read and read and cant find much to tell me how to change the WM6 IP BLock to something like 192.168.2.1 rather than the default 192.168.0.1
Does anyone have any pointers? Ive looked through the registry. There MUST be a simple way to change a default.
To clarify my setup, I am using ICS Via USB into a UMPC laptop running XP. The UMPC is set to share that same connection back out over Ethernet. The ethernet runs into my WAN Uplink on the router and then back out via wifi/rj-45
This setup works as I have done it using Wifi with other networks, and I can chose the "Lan3" to share under the advanced settings on the UMPC. The reason I dont just share out via Wifi from the start is that Wifi on my Kaiser and Raphael both make the device to hot to charge, thusly killing the battery within a couple hrs of sharing. If I share via USB , it stays pretty cool and still charges.
Anyone have any pointers?
I have already tried tricking XP into using the Lan on another block but as soon as you try to share the USB lan, it reverts back to the 192.168.0.1
The only way I can imagine is a registry modification or a program change in ICS.
Thanks Much!

remote desktop problem

Hi everyone,
I would like to connect to my laptop next room from local network. I can connect perfectly when I type in my IP address into the first textbox (Computer), but I can't connect when I type in my Computer Name (full computer name) instead. I tried MyPCName as Computer, \\MyPCName as Computer, forwarding port 3389 to my IP, leaving domain name empty, putting in my workgroup name as a domain, putting in my computer name as a domain, putting in myPCName\MyUserName as Username, \\MyPCName as Computer, still the same. It won't connect unless I put in the IP address. I would like to do this since my workplace assigns a different IP to my laptop then I assign at home, but naturally I have the same computer name at both places, so I would like to have a permanent setting for both places.
I'm running Windows 7 64 bit on my laptop and 1.66.405.2 ROM on my HTC HD2.
Many thanks in advance.
can you connect to it ok using another computer? might be a dns issue at a guess...
I can connect from other computers fine. Also on my HD2 I can see the host names of PC's under Resco Explorer and map them. However, remote desktop mobile refuses to work with the Computer Name. I can ping my Laptop's IP and also Computer name from pingbox2. Only in Remote Desktop Mobile there is a problem.
windows 7 by default blocks remote desktop connections from different versions of remote desktop. if you right click computer and select properties, then choose remote settings on the right hand side and select the middle option (accept connections from all verions of remote desktop). havent tried this my self but it solves most issues when using different versions of windows
OK, I sort of figured it but would still appreciate some help. Here is how I got it to work:
I had OpenDNS IP under DNS settings for wireless adapter. I deleted them. If I don't do this, pinging my computer name from HD2 always brings 67.215.65.132, which is opendns and not my true local IP, i.e. 192.168.x.x. I also had to disable the data connection (3G) and only have wireless. If I don't disable 3G, I can only connect with IP and not computer name. Only after doing these 2, when I pinged my computer name, I got the true local IP and I was able to connect with Remote Desktop Mobile using computer name. Now my question is:
1- I don't want to quit using opendns, is it possible?
2- I don't want to disable 3G connection every time, is it possible?
thanks in advance.
For me it works with MyPCName in computer and empty domain, both for XP and 7.
Something seems strange with your phone's networking configuration. At a guess (and this is a long shot), I would check your VPN settings on your phone to make sure you're not connecting to a different domain over 3G as this might explain why it works when you turn off the data connection on the phone and why it works by IP address.
As I said though, it's a long shot and is the only thing I could think of that fits your particular symptoms...

2- I don't want to disable 3G connection every time, is it possible?
thanks in advance.

about the open dns issues, I suspect that can be solved by making sure your router lets the incoming connection into your home network (you say it resolves to 66.whatever when open dns is used, shouldn't be a problem do long as you don't forget that will be your home ip address so that connection will neef to be allowed through the router and then forwarded by your routers virtual server (our whatever your router software calls out) to your laptops internal ip address.
as for the 3g it should use wifi over 3g by default..... mine certainly does, no need for me to disable it.

Something seems strange with your phone's networking configuration. At a guess (and this is a long shot), I would check your VPN settings on your phone to make sure you're not connecting to a different domain over 3G as this might explain why it works when you turn off the data connection on the phone and why it works by IP address.
As I said though, it's a long shot and is the only thing I could think of that fits your particular symptoms...

I think you're right, when the 3G is on (and also Wifi on), Resco shows computers from all around the country when I click computers near me and not my local network. When only wifi is on I can see my local computers. 3G probably has precedence over Wifi? How can I correct this?

But the 66.whatever address is generic openDNS lookup IP and same for everyone. Are you suggesting me to route this IP to my local IP, i.e. 192.168.x.x? Oh, one more thing, I can also connect when 3g and wifi are both on, but only through computer's IP and not computer name. Can you connect with computer name while both are on and connected?
when your phone does a dns lookup on the name it resolves to the open dns assigned address (not the same for everyone, otherwise the open fns system wouldn't work) so to connect to your computer the phone sends its request to open dns who forward that request to your current actual address.at home that address is your home ip address BUT it isn't your laptops address it is your routers address.(stop reading here if you don't have a router).
so the router needs to be told "if you get a connection request in port (whatever the remote desktop port is) please forward it to (laptop ip address)
its called port forwarding in some routers, virtual server in others.

You're mixing up things a bit - he's not using dns but the computer netbios name. The point is that he has wifi on and connected as well as 3G, thus with an "intranet" ip address on Wifi... so the program/phone should be looking up the name on that connection, where it would find it, instead of looking up over the 3G connection. As the netbios protocol is not routable, it has no chance of finding the computer name over 3G/internet and back home, even with port mappings.

you're totally right, I have a router and its port is forwarded to my laptop IP, but this is only good (and works well too) when I want to connect from Internet to my local network. I tried OpenDNS exceptions for VPN and defined an exception named as MyComputerName but it didn't work. Then I tried a dyndns solution, but it only works for external connections and not local network, i.e. it can't map local IP's. What I need is a dynamic client which can update my local IP.
I also tried to edit hosts entry in the registry with MyComputerName. It works for a single IP, but I'm not sure if I can write multiple IP adresses (my work and home local IP) into that. If I could maybe everything would be OK.
I've just tried a couple of things and it really works fine for me. If I connect Wifi only, I can remote desktop with the computer name. If I then connect data connection, it still works. Disabling wifi and obviously it doesn't work anymore. Re enabling wifi, it doesn't work at first, but does again after ~30 seconds once the netbios protocol has done its host lookup procedures.
There simply shouldn't be anything special to do.

thank you very much for your time, I appreciate it. You're right in that waiting a bit resolves the issue (it's a bit more than 30 secs for me that's why I thought it wasn't working when 3G is enabled) but only when OpenDNS is not used. I assume you don't use OpenDNS, right? Once I put that one into equation, it takes over NetBIOS protocol and returns its IP instead of the local IP(192.168.x.x). As far as I understand, DNS lookup has precedence over NETBIOS and if the name is not found in DNS it consults NETBIOS protocol. However OpenDNS has this nice "feature" where it finds the name with its own IP. There are several posts about this on its webpage and they say to either disable the typo correction or put exceptions for Netbios names, but sadly none of them works for me right now.
Nope, no OpenDNS, never actually heard of it.
How does it work? Do you enter their DNS server address in the network settings of your pc/phone, or is it an app you run?
you click Start/Settings/All Settings/Connections/Wifi/First Button/Switch to Network Adapters tab/Select Broadcom 802.11 DHD Network Adapter/Switch to Name Servers Tab/Type in 208.67.222.222 for primary DNS and 208.67.220.220 for secondary DNS, click OK. that's all. Could you try if it's not so much trouble? Thanks.
OK, remote desktop doesn't work either with the OpenDNS servers in.
I'm pretty sure it must be a limitation of the remote desktop app itself, as resco explorer can still navigate and/or discover the network shares of my other PCs with no problem. NBTStatCE also finds everybody.
Wouldn't even surprise me, as that Remote desktop mobile has always been troublesome. I don't remember exactly, but in the WM5 days it was pretty much impossible to use on a local network due to a weird handling of names... if I remember well all "local" (NetBIOS) addresses without a '.' entered in the remote desktop app would be redirected to the "Work" connection, while "remote" ones with a period would be directed on the "Internet" connection. As a network card can only be defined as one of them, if you wanted it to work in both cases through Wifi you had to switch the card from Work to Internet and back all the time. And of course when it's on Work it breaks some other things that use the default system handling like mail.
