DNS error? - data connection unusable - Networking

I experience a very strange behaviour in my eyes and did not yet found a solution here.
Conditions:
-WinMo 6.1 on SE XPERIA X1 using different cooked ROMs, maybe also the official ROM
-automatic SE or manual connection setup used for t-mobile DE
Error characteristics:
-data connection itself (GPRS connection either on 2G or 3G network) is active
-applications can't connect to any site (opera, htc weather, quickgps)
-but if IP addresses are used instead of names then connections to a web-site are successful (A direct IP address http://209.85.129.132/ does work, but not http://www.google.de/ e.g.)
-the error is somehow reproducible, but it can not exactly figured out under which condition it appears
-the error stays after power off or soft reset, only flashing the rom new helps
-the error does start after a while (hours/days)
-the error seems to be somehow in conjunction with switching network type between GPRS, WLAN and using the Internet connection of a PC connected with ActiveSync, but there is no unambiguous correlation distinguishable when the error starts
solutions:
-my first idea was that DNS service on the X1 is somehow not working, so I used openDNS specific adresses for the DNS server instead of the server-assigned addresses, but the error stays
I hope you have any ideas for me?

confirm error by my Xperia
Hello yesterday i posted the same error by a rom Thread,
had the same error on 6.5 and 6.1 with skyfire the internet works but Weather, QuickGPS... don't work, hope that find a solution for that.

Hi everybody,
I have exactly the same problem with o2 Germany. I tried it with the open dns servers but still the same network error occurs... Has anybody solved this?

Hello,
I have a similar problem when I'm using for my wifi static ip and manually settings for DNS. At home I'm using static ip settings for my wifi, so after i closed my Wifi connection on the Blackstone my Opera at GPRS/3G connection will not disolving the URL like www.google.de but when I'm using the IP it works fine. My workaround is to delete the static IP settings and the entry for DNS and the the desolving of the URL is working.

problem solved

thanks bieza, that worked for me as well . i had only static IP (with auto DNS) for WiFi, and dns was failing for cellular connection (EDGE). changed wifi IP back to auto, and problem fixed.
interestingly, when DNS was not working for EDGE, i could use ICS as usual. i was browsing on PC, but due to DNS problem nothing was working on the same phone.
it's a touch (ELF 64/128) running on ONYX 4.6.

VPN through 3G problem

I have problem with VPN connection to my privat network.
VPN connection works if I am on cable, wifi, but whan I am connected over 3G, HSDPA, than my connection works for about 5 seconds and than I hear sound from WM6 side that my 3G connection was broaken.
I can go to WM side and try with VPN connection there and it wont connect. But strange thing is, that if my VISTA is shutdown than I CAN connect with WM6 to my VPN server.
Please help if sombody had the same problem...
bye
Matkosan
I setup Hamachi yesterday on my Shift, on both the WM and Vista sides of the device and it worked perfectly. Of course, each "side" looks like a completely different node on the network, but it was really cool to remote desktop into my home and office machines from VM.
Regards,
Dave
Which VPN client software and version are you using? Or is this window PPTP vpn?
I had some problems with Cisco VPN Dialer client and the pasword manager function of the finger print reading software. Once I turned off the password manger function both the VPN dialer and finger print reader are happy to coexist. ( issue might not be problem if you are not using a RSA fob like I have to)
I am using both on my shift Cisco VPN for work and the Windows PPTP connection to reach my home network. So I can confirm that they both work from Vista and that windows PPTP works from WM6.
Nothing special, just window PPTP vpn client. My internet connection works perpectly, but when I make a VPN connection, 3G just drops the line and than reconects when I disconnect VPN connection... But VPN is allways working for about 5 seconds, a few successful pings...
I just used the magic button FN+F3 and whn vista come up i have the same problem. That means that tre problem resides somewhere in WM part. I am still looking... The problem could be that my service provider and my contry are not on the shifts list, so there could be some connecion settings problems... On my other sony vaio the same data card and HSDPA connection and VPN works OK.
Now I am playing with WM side. I can establish VPN connection to my server, bat as soon as I try to send over some data it simply diskonects 3G connection and that establish it again, without VPN connection afcourse.
So my connection to VPN is working, but when I start internet explread try to conect to any web site, 3G connection restarts.
Any suggestions or somthing....

Hi.
Is there a fix to this? I am getting exactly the same problem. 3G works for surfing on vista and exchange push/browsing on WM side - As soon as I put a pptp VPN across to the work network, the 3G on the WM side drops, and if I am looking at m network connections in Vista, the "LOCAL AREA CONNECTION 2" network "card" disappears from network settings and the VPN stops.
If I disconnect the VPN, the 3G connection restores itself and I can browse again.
any help appreciated as I need pptp to work so I can ditch my laptop!

Have you tried going into the TCP/IP properties of the VPN connection, then 'Advanced' and removed the tick from 'use default gateway on remote network'. That fix the problem for me.

Yes, I did that, but then the internet works fine and the VPN and the 3G stay up okay, but everything seems to go to the local internet and nothing goes via the VPN tunnel.

Hi,
Probably you have to change the MTU settings in the Local Area Connection, here's the command:
netsh interface ipv4 set subinterface "Local Area Connection" mtu=1440 store=persistent
1440 is only a suggestion. If you low more the MTU you will notice a decrease in speed/bandwith but 1440 will be unnoticeable and will let VPN connections work.

Have you actually got a VPN session working? From what I can see, the problem is the way that the Vista side uses the modem.
If I do a route print from Vista with the VPN up, it doesn't add any routes, so sends all traffic to 192.168.160.1, which appears to be the IP of the modem/WM side of the device.
If I manually put in
ROUTE ADD 0.0.0.0 MASK 0.0.0.0 192.168.99.1
Which is the IP of the VPN router, all traffic gets routed out down the VPN and it works for about 5 minutes, then the "Local Area Connection" network card in Manage Networks, disappears. If I then drop the VPN (because strangely it stays up) the LAC card comes back...

I didn't tried to establish a VPN with my Shift, but I found this MTU problem with many GPRS and 3G connections when establishing VPN (PPTP and also IPSEC ones).
I don't see how to help you more, sorry

vista utilizes ICS from WM6 to get the connection. that's why you see 192.168.0.1
We had a similar problem with Cisco VPN Client constantly disconnecting when using 3G Cards. We use a Cisco ASA 5510.
One solution is to disable the Keep Alive function in the ASA for the specific VPN Profile.
Hope that helps!
Try your Networks VPN APN - it could be an IP conflict.
I tried cisco vpn client over hsdpa and it worked.
I still have problem connecting with microsoft PPTP client. After few seconds connection vista-wm just drops and comes back again when PPTP client disconects.
Problem is ICS from WM6 in my appinion...
Please help me

Wifi Connection issue: DNS not assigned

Hi everybody,
I have the same issue for a long time.
I connect to a wifi connection with DHCP enabled.
My Wifi connection works correctly, DHCP assigns my device an IP address but DNS stays empty in Wifi options.
I succeed connecting to a website if following these steps:
-I manually enter a DNS server IP.
-This stops the wifi connection
-I restart wifi
But then if I stop wifi and start it again, I cannot surf anymore.
I have to manually change DNS again (switch main and secondary DNS IP addresses)
Am I the only one to have the issue, or has someone heard of a solution ?
Any help welcome .
No one has an answer to the same problem I have too ....
No DNS if wifi is connected, on 3G it is all working fine ...
No one tests for DNS problems in cooked roms on this site ...
i would look into the settings of the wifi router to discover why it's not providing a valid dns
as it's normaly does when the wifi is set correctly
That certainly sounds like it could be the issue.
In case anyone is looking for quick and reliable DNS servers, try these 4.2.2.2 and 4.2.2.4. I seem to remember they are AT&T's but please don't quote me on that.

How to configure the WiFi Router application?

Please assist.
1. My PC identifies the HD2 as Ad-Hoc and not as Infrastructure. Is it the case?
2. The WiFi router application registers only the WAP APN in the internet connections. I usually use the Internet APN, why is it not chosen?
3. On my PC, should I enter the 10 digits WEP key for all four WEP key slots, or just into the first slot?
4. When I try to connect, the HD2 prompts me to enter a Static IP address (no DHCP support). Where should I enter it? what mask and gateway addresses?
Thanks
anyone using that app?
I tried, but I can't. Unlike the original poster, it tries to connect to my MMS access point, of course there's no internet access there. I haven't been able to figure out how to make it work yet.
Mine works perfectly but only if the HD2 is right next to the computer. For some reason the range is ridiculously minimal.

Battery drain, if the range was increased it would kill the battery.
I have the same problem as the first poster : I can't choose the correct 3G connection. Only one connection is displayed in HTC Wifi Router with one single radio button on its right and it's not the right internet connection for unlimited internet.
in order to choose the right APN, please choose SETTINGS>CONNECTIONS>CONNECTIONS>ADVANCED>SELECT NETWORKS and enter the right APN (Internet) in both tabs.
That will do the trick.
still, although HD2 is discoverable by my PC (in wifi Find networks), with a good reception level, my PC insists that it is an Ad-Hoc connection (no DHCP) and when I try to use Infrastucture (with the wep key), my PC cannot establish association (get IP address from the HD2) and it shows no signal level.
Please assist.
Zolom, thanks? I did that and it improved a bit the situation: now email clients work (pop) but web surfing still doesn't work. I didn't try yet other internet connections.
not working anymore
before i installed 1.48 everything worked perfect but after the upgrade it doesnt work anymore. now my computer can connect but the phone also connects to its own network.... very strange behavior.... tried to turn off wifi but that also turns off router. any suggestions anyone?
Voila I finally got rid of the "HTTP 403 Forbidden" error with a (partial?) solution.
I have installed user agent switcher (http://chrispederick.com/work/user-agent-switcher/installed/07/) for Mozilla on Windows Vista, and I entered the user agent of my ISP on my HTC HD2 . It works!
Questions:
- Is it possible to set the user agent on other browsers such as IE or Opera?
- I noticed the user agent is not necessary for pop3 email clients. Is user agent mandatory for other internet services, like Messenger, SIP, Skype, software updates, etc?

Wi-Fi router

All
I have my htc setup to both internet sharing and Wi-Fi connection on my work PC with a lan connection. On both of these connections e.g. wired USB and wireless i can get the internet for about 3 minutes then it stops working. Is there some sort of block? I did see a while back that the WiFi app has no restrictions...
Any help would be superb.
Cheers
Baker0
Thats a little odd, there is certainly no block and I have had the wifi router running for a good 30-40 minutes without failing.
what part is failing, is the phone no longer running the wifi router, or is the pc no longer getting internet on that network connection?
If you need help on how to find this info just reply and I can walk you through some more diagnostic steps.
The phone is still running just the internet stops on the machine. I have to stop the wi fi on the phone then start again then connect. I think it might be t-mobile but the internet on the phone is fine
are you in the uk?
if you connect your laptop to the phone via the wifi router you should be able to right click the network logo, click on status and view the wifi network info, it should tell you in there if it has internet access on that network connection.
If you try this again and when it fails check this status window and see if windows is seeing an internet connection or not?
when the net fails again try and visit http://72.14.203.100/ (this should be the google homepage) if you see google then there is a dns problem if it still says network timeout or failed to connect or something like that then we will have to dig further.
LOL thanks for your help. I am in the UK. ive been working in IT for the last 12 years and I know and have done the test, its not the machine it has something to do with the phone or t-mobile network
Sorry to hijack your thread a little, but I'm on the T-Mobile Network in the UK too (except I'm using a Touch Pro with a custom ROM), and although I can make connections from the PC to websites using the IP address, the DNS isn't working so I can't resolve domain names.
Any ideas?
Cheers,
Steve.

It must be the phone then since I do use wifi router, I am on t-mobile and in the UK and I do not experience this :S
I seem to be saying this more and more but maybe you should try a hard reset and see if that fixes the problem?

This is likely an issue with the way your machine has been setup to connect to the wifi network. Try visting the properties of the network and vieing the dns settings for the tcp/ipv4, It should be set as Obtain DNS server addresses automatically. If it is set like this then try setting it too 8.8.8.8 and 8.8.4.4 these are googles, dns servers if this works for you then you could stick with this or do some further digging as to why you are not getting the dns server addresses automatically like you should be.

Setting the DNS entries to Google's makes it work, but attempting to get the DNS Server's automatically leaves me with no ability to resolve domain names. How strange?
Thanks for the workaround, not sure where to start looking to fix it properly.

Hey guys,
I am new to this wifi router thing and got the following questions:
1. To be able to use it, you must have data connection with your provider. Am I right?
2. By any chance, can I use this system by using a sim taken out of a prepaid mobile broadband dongle and inserted into my device (htc touch HD)?
3. Once I get connected can I surf the internet/check emails etc from within the device itself without the need to use a laptop?
Please don't mind these basic stupid questions.
cheers

HD2 Android WiFi Problem - Experience Sharing

The strangest thing I have even experienced, and perhaps can save you time and headache.
** Summary (for those not wanting to read the whole story, but just the fix)
If your HD2 Android can connect to your home WiFi but cannot access Internet, check if your WiFi network uses a 192.168.20.x IP subnet address. The HD2 Android's USB port uses the same subnet, causing a conflict. If you change your home WiFi to use any other subnet, it will work fine.
** The Long Story
Been reading and admiring all the Android developments in XDA-Developers for some time, finally decided it was time to give it a try. Picked one of the more popular and stable MDJ Froyo (Desire HD) for SD and loved it.
Problem is couldn't use the Internet via WiFi from my home. Internet via GPRS works fine, Internet via USB/PC works fine, just not WiFi. The connection to WiFi is successful, picks up a DHCP IP address just fine, but no Internet.
Oh well, perhaps there is a WiFi bug in HD2 Android not reported so never mind.
Wait! On a business trip, when HD2 Android connecting to the hotel's WiFi, Internet works fine! Subsequently in many other places WiFi works also flawlessly.
Must be the WiFi router at home. Not too surprising as I don't use much wireless but wired all my other computers (including notebook PCs), it is faster anyways.
So went back and tested WiFi on a notebook PC (prior to that upgraded the WiFi router's firmware), PC connects and works, but HD2 Android still not. Tried all kinds of WiFi and encryption combination (BGN, BG, G only, WPA2, WPA, WEP), just nothing works for HD2 Android. >> Conclusion: not the WiFi router at home, just HD2 Android working with this particular WiFi router.
Finally (but forgot what app it was), I saw the USB port binding to 192.168.20.x subnet, exactly the same as my LAN subnet in the WiFi router.
Bingo, changed the LAN subnet to something else (really anything is fine because it is inside a NAT so not an issue getting out to the Internet) and HD2 Android works like a charm.
Hope this helps.
sorry, can you explain more where to change in the router settings? i can't find anything to change in my wireless settings
Look up the LAN (local area network setting) in your router, where the IP address for most WiFi router is set to use 192.168.0.1
In my case the WiFi router is set to use 192.168.20.1 (and DHCP to pass out 192.168.20.x IP addresses).
By changing the IP address of the router, most router automatically change the DHCP assignment to corresponding subnet, say from 192.168.20.1 to 192.168.x.1
x can be any of 0 to 255, just not 20 for my case or it causes conflict with HD2 Android.
Hi Dear friend , And Thanks for sharing experiences.
I have the same problem , but my router's setting is :
IP Address : 192.168.1.1
and my Starting IP Address : 192.168.1.100
IP Pool Count : 101
DHCP : Enabled
NAT : Enabled
Default Route : YES
but no webpage loaded , the weather not work . but the meebo messenger
with my yahoo ID just worked .
so how can i fix it ?
tnx
I notice the conflict (with my 192.168.2.x) when I checked the HD2 IP addresses (after connecting to the WiFi). When I see the USB port bound to 192.168.2.x I know the two just conflict with each other.
If something (meebo messenger?) works but not others... could it be your HD2 not getting name resolution (DNS ?). Say if you try opening this do you get the Google page:
http://74.125.153.104/
** This is Google's page without the need to resolve via DNS.

hi my friend. I tested it with IP but nothing changed.
but some of the WebSites with SubDomain Loaded. like : http://2.farsihiphop.com
and can u tell me how can I know about the port nimber . like USB port.
i think my Android's Kernels have been changes. maybe i'll can find something like this (equal IP address)
thanks.
I have following problem : At my university i have hidden Wifi network, locked with password.. But, ofcourse, we cracked their password, and now we can use their WiFi.. But i cant use it.. On WM i could use it .. One more thing to mention, there is a proxy u need to setup before u can go on internet trough that Wifi network.. but thats not my concerne yet.. I cant get connected to that Wifi.. I make new conn, with password and other settings, and it keep saying : Connecting... Disconnected...
Any ideas to help me ?
Thanks in advance
I had the same problem. I solved it by updating the radio to version 2.14.50.2. I think this version works best.
For me 2.15.50.14 works, too...
