Connecting point to point with another WiFi device - Networking

Hi,
I would like to know if the following is possible:
1. Use a PDA with WiFi configured with a static IP address
2. Use another WiFi device (PC, Web Cam, etc) with a static Ip address
3. Connect the two together point to point - No WiFi access ponit, etc.
In my minds eye this is straightforward and I don;t imagine I need a hub.
Am I right?

Socket SDIO WLAN card in I-Mate II

hi all,
Can't seem to get the Socket SDIO card working on my I-Mate II. Everywhere I look it seems like it requires SDIO NOW from bSquare but yet some posts say they get it working.
Anyone had any luck on this with a repeatable process documented?
Thanks!
Randall
Re Socket WiFi SDIO card
I had the same problem, but it's working fine now. First, get the latest driver software from Socket and install it. Then insert the card and wait several minutes until the wireless icon appears on the top bar. This will list available wireless networks in a bubble. Select the one you want and select to connect to the internet. It will then ask for the WEP key, if you need one, which you should enter as hex or ASCII. It should now be working.
Hope this helps!

Yeah I already did that one . I had it working for a little while last night but can't seem to get it going again.
Update: SDIO Issues
Hi all,
Where I have discovered something interesting. If you broadcast the SSID, then you can connect without issue using the Socket SDIO card. ( I assume it will be the same thing for the SanDisk Card as well)
I couldn't connect to anything until I started broadcasting the SSID. And here at work today I can connect to the AP's that broadcast and those that don't I can't no matter what I do.
Do I smell a bug here? :-D
i always seem to get a problem of not receiving an ip address from my linksys router. as soon as i put a static address in, restarted, reset it, restarted again, it worked...

>How do i access & broadcast SSID ? I have a SanDisk SDIO WLAN and i am experiecing problems now with access public access hotspots which i never did. The IP assigned to me are always the same despite having resetted my XDAII. Thanks sir.

hihi something to share with u all, me also having the same problem of not able to connect with my linksys router with SSID broadcast disable. I tried with both sankdisk n socket driver, both also can't work. But i have no problem with getting any ip from my router
In short:
The SocketIO 802.11b SDIO Card, like most 802.11b devices, will not connect without either enabling SSID Broadcast on the Access Point OR manually specifying the SSID in the setup of the wirless profile of the connecting device (the XDA in this case).
In not so short:
In infrastructure mode (connection from Client to Access Point (AP)), the client sends all traffic to the AP. The access point acts as an ethernet bridge and forwards the communications onto the appropriate network–
either the wired network, or the wireless network. Prior to communicating data, wireless clients and access points must establish a relationship, or an association. Only after an association is established can the two wireless stations exchange data. In infrastructure mode, the clients associate with an access point. The association process is a two step process involving three states:
1. Unauthenticated and unassociated,
2. Authenticated and unassociated,
3. Authenticated and associated.
To transition between these three states, the communicating parties exchange messages called management frames. All access points transmit a beacon management frame at a fixed interval. To associate with an access point and join a BSS, a client listens for beacon messages to identify the access points within range. The client then selects the BSS to join in a vendor independent manner. For instance in Windows XP, all of the network names (or service set identifiers (SSID)) which are contained in the beacon frame are presented to the user so that they may select the network to join. A client may also send a probe request management frame to find an access point affiliated with a desired SSID.
After identifying an access point, the client and the access point perform a mutual authentication by exchanging several management frames as part of the process. The two standardized authentication mechanisms are Open System Authentication and Shared Key Authentication.
After successful authentication, the client moves into the second state, authenticated and unassociated.
Then the client sends an association request frame, and the access point responds with an association response frame, which moves us from the second state to the third and final state, authenticated and associated.
After following the process described, the client becomes a peer on the wireless network, and can transmit data frames on the network.
The problem is, if the SSID is not being broadcasted in the beacon frame, the client does not know who to respond back to. By specifying the SSID the client will then be able to establish communication.
Thats my understanding of the process/problem anyway.
Note: In my experience 802.11g is not subject to this limitation, my guess would be 802.11g uses the AP's MAC address in addition to the SSID (if enabled) in management frames/association.
Hope this helps..

WiFI Problem - Question

Hello to all, I have a small (if therefore I can call it) problem with WIFI.
I have 2 access point, between house and office, all configred in the same way.
The problem is that with the P3600, i can connect on all of two, correctly aquire IP address, but i can surf Internet only to access point 1 (for example).
If I try instead being connected with the laptot PC there is not problem… It goes. Can you help me?
I try also to configure ip manually on 3600 but the result is the same.
I don't understand why i can surf on access point 1 and not on access point 2.
first thing i would check would be the dns... grab the ip for something and see if you can connect to it from the one your having problems with... if so its a dns problem!

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...

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.

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.

[REQ] Set Static IP in WP7 ?

Hi guys ..
How can i set a static ip in WP7 on HD2 ??
currently not possible
holy crap thanks for the reminder! as i kept thinking something was missing.
iphones (no matter how simple) could do it, and here I was thinking Microsoft is the king of networking....
Actually if you really want static IP, you can "push" to it. If you find out your wlan MAC address, use your router to assign only the IP which you select.
To find out your MAC address is simple: connect your phone to wifi, connect to router and see n the logs (even the dumiest routers keeps logs of what wifi cards are connected to it)
Just a small idea....
Rgs, Seba
Yeah my router thinks there are 5 mac addresses logged onto its wifi, but each time wp7 has reset its created a new mac.

Hotspot Issues

Considering that CM12.1 has a defunct USB connection - only charging and ADB work, MTP doesn't - I've used WiFi File Transfer to send files to my phone instead of using a USB connection for it. MTP works if you put it in Recovery Mode, but I'd rather not shut down the phone. My phone is an A3FU, by the way. Anyway, so sometimes, I'm in a place where I don't have any other wireless networks to connect to, so I have to make a Hotspot in order for the app to work. And it actually worked very well, up 'till a couple of days ago. Now, the Hotspot connection doesn't go properly. I'll try to clarify. When I start a Hotspot on my phone, my laptop can connect to it, but the configuration is all wrong.
My laptop is issued the following IP address 169.254.184.177, and the Subnet Mask is 255.255.0.0. On the other end, my phone's (the Hotspot host) IP address is 192.168.43.1, Subnet Mask is 255.255.255.0. Other devices that I tried to connect to it, had similar issues.
The problem is resolved if I manually configure my laptop's IP address to (for example) 192.168.43.4 and set the Subnet Mask to 255.255.255.0, but other than that, I don't know how else to fix this issue - hell, I don't even know where the issue is, exactly.
So, any help in this matter would be greatly appreciated!
