DNS error? - data connection unusable

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.

Try Entering The DNS Servers manually in the setting try open dns servers.

Resolver2:208.67.220.220

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.

Any solution??

wireless connecting but no internet

Hi everyone...
I have a touch HD that is not getting anything from the Internet even though it is connected to the wireless network. I was told that this problem started when the new proxy server was implemented and it applies to all windows mobile devices. I have checked the proxy settings and they are right. The Internet works fine at home... it just does nothing at my work.
Any ideas would be highly appreciated.
By the way... I have tried the solutions mentioned around here - like changing the channel - and nothing works.

Hi,
im facing the same problem and i suspect my WLAN access point. It works on all Wireless unless mine at home. I`m using a Zyxel Router.
Are you using DHCP? The answer from zyxel was to change the ip settings on my HD to static - means manual IP, Gateway and DNS.
It works now for a minute or so but then again dead. Now using data flat from my mobile company.
Hope this helps.
Regards,
Nils

Thanks for your reply...
I have tried that.. but I cannot get anything to work...
I will try again... although one solution I want to try is to find a way to share my laptop's connection with my mobile and use it while I am close to it... but wireless connections cannot be share it seems...
anyway, thanks.

sounds more like it's you adhoc wifi on the laptop which is the problem
you have to set it up to work on the laptop for it to ever share with a pda

Actually it connects to the wireless router. There are three access points at work and I have tried to connect to them all. The only difference between these and my home wireless connection is the proxy server at work. I tried every possible solution with no success.
Anyway.. I will try something new when the weekend is over.
Thanks anyway.

OK. So this is how it is:
I got the internet to work by using a fixed IP instead of the dynamic IP assigned to me by the DNS. Once I supplied my username and password I could access the Internet. However, the touchflo interface cannot access it.
Is there a way to configure the HTC touch flo interface to set the proxy for it?
Regards

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

can't use internet OVERALL via wi-fi!!

i have problem with using INTERNET via wi-fi, i'm using [mattc Leo + Froyo w/Sense RC1.3a].. is that just me who have this problem??

I use this version on my wifi and it works very well what is the problem, can you connect to the wireless network ?

thx for your reply
strange!!! it's work now for me
first was seen connect to the wireless network but could not surf ... etc.
anyway it works now!

No internet when switched to WiFi
I have the same issue. No internet when WiFi is turned on with darkstone HD2Froyo, Kernel 2.6.32.9-38076 (Cotulla 25/07/2010). I can ping my HD2 from my network over WiFi.
Seems as if the default gateway on my HD2 is not set in that case.
Is there an app to check the current ip settings?
I´m also wondering about the strange mac address my dhcp server shows me
00:11:22:33:44:55

^ that is the MAC address of your HD2 on the current Android build. We all have it -> CLICK
If you are usin MAC address filtering on the WiFi router, this is your problem - edit the MAC address list

Long shot but this worked for me.
wi-fi has worked no problem on most builds but anything with sense on it just wouldn't find my network, would find networks all around me but not the one sat next right to the phone!!!
Changed the channel on my router from 13 to 11 and hey presto, picked it up straight away

Tould you that i can ping the device so this has nothing todo with mac filtering.
Any other ideas?

I'm using the Darkstone Froyo build and WiFi works a treat when you enable it, the problem with it is that when the device is not in use and you activate the screen and unlock it, 9 times out of 10 it will be using 3g instead.
If you go into Settings -> Wifi it says "turning off"... then immediately goes to connecting to my home network wifi and all is well... ok, all is well until next time the device is idle

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.

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...
