My Wifi connected to my home router perfectly until I flashed the custom rom.
Now it wont work. the phone recognizes my network, then tries to connect but it pauses at the obtaining ip address bit and doesn't connect?
I tried to restart the router. It doesn't work.
I tried to reflash the rom or offical rom (KE7). It doesn't work.
I also tried to delete the file /data/misc/dhcp/dhcp_list, but there are no "dhcp_list" file inside 'dhcp'
Do anyone have another way to solve this problem?
Thanks
Could be a problem with the router, are other devices able to acquire IP addresses from it correctly?
Perhaps you should assign a static IP to see if that makes a difference.
I am on KE7 stock rom with root and had this problem too. It just started yesterday and got stuck at obtaining ip adress. So I switched WIFI off and flight mode on and after some seconds wifi on and flight mode off and it connected. I also noticed that now sometimes when it is in standby it disconnects from the wifi network (but wifi is still ON) and when I wake it up it connects to my network.
Me too, same problem.
If wifi is ruled on "sleep when screen turn off", it don't wake when screen turn on.
It stay on " searching for IP adress...".
For the moment, I'm forced to leave wifi on "never" and I use Juice defender for disabling wifi on screen off.
I really think it's a common pb with SGS 2. May be it will be fixed with 2.3.4.
Same problem. I 'fix' it by turning off wifi then turning it back on and it gets an IP address immediately.
same problem here with a dlink dir-615 router. from time to time the phone can't get an ip, and it only works if i reboot the router. didn't try with another router yet ( well, i connected to a few more but not frequent so i can see if there are problems), but i ordered a new one anyways since the dlink also crushes my battery too.
try posting the brand/model of the router you have problems with, maybe there's some specific ones that are troublesome.
d-link dir-615 here / ke7 stock - rooted
I also have a dlink router. But I get the same problem with a Belkin.
With my first SGS, no problem. I really think it's a specific issue on SGS2.
I'd read in some place that 2.3.4 will fix some wifi problem known for the moment on 2.3.3...
Let's see...
I'm seeing this with both my home router (Netgear WNDR3700) and my office router. Disabling & re-enabling WiFi on the SGS2 solves it -- fortunately, it's easily accessible on the notifications panel.
Same thing with Dlink dir 815.

Same thing here with Draytek 2820 router, all other devices (PC's Phones, PDA's etc) have no problem. SGS2 however needs WiFi turning off when waking from sleep to get it to obtain an IP address again. However my HD2 also running Gingerbread 2.3.3 works faultlessly.
KF2 seems, for me and some others, fix the problem...
hi
lucky me, i thought im the only 1 having problem with wifi
my problem, same as the others
the wifi try to connect (obtaining IP) and then disconnected
it will scan again, same thing will happened
try with all type of protocols, wifi b,g,n wep, wpa, no passwd
results still same
try to connect wifi at my office, results also the same
im on KF1 using dlink 615
hopefully someone can help us
tq
Just got my Galaxy S2 today. Cannot connect to wifi network on G or mixed mode, with or without security - just tries to obtain an IP address. Ridiculous.
Any help ? Quick search on Google doesn't bring up too much. There does seem to be an app called "FXR Wifi" but I don't expect to use that on a brand new phone.
Update: Upgraded my router's firmware (WRT54GS) and it works !
I have the same problem with my SGS 2. I can't connect to an AP - NETGEAR DG834G.
I found a partial solution to use my phone with my AP until I solve the problem. In the Wi-Fi settings menu enter Advanced mod and set the IP address, Gateway, Netmask, DNS1 manualy (by touching <Use static IP>). If you don't know what IPs you have to set for IP address, Gateway, etc. just connect with you laptop or desktop and use the settings from your computer. Just make sure you type a different IP address in your mobile (not the one from your computer - for example in you computer you'll find something like this: 192.168.0.3, you'll have to type in your mobile something like this: 192.168.0.10). The rest of the settings have to be identical.
Good luck!
To solve this "obtaining ip address problem". Set the following manually in the advanced configuration and save it.
1. ip address(your choice).
2. subnet mask(255.255.255.0).
3. default gateway(192.168.1.1).
4. dns servers(8.8.8.8,8.8.4.4)
Note: The above given values are the most commonly used, you change it if you want so.
After entering these values manually(and correctly), it will connect to the networ in 1 or 2 seconds.
like mine SG s2, wifi connects works perfectly at home and friends place,
but stucks at obtaining ipaddress for wifi, at the mall and college, ( where it needs first login page for authentication) ( or to agree user terms and regulation),
any idea, how to fix this issue.
Thanks
mine also does this where it doesn't get an ip. Reboot your router or just disable and re-enable the access point feature on the router and it should work without having to reboot it

Hey guys! Did you find a fix for this problem? I have the same thing happening right now. I tried at different places, home and country house with Zyxel P660HN and Cisco E4200 respectively. Stuck at obtaining IP address...

thanks in advance!
today, i connected just fine on one open ap, and one wep protected ap, but i still can't connect to my home wi fi ap. really confusing. my laptop and old htc prophet connects just fine, but my new omnia 7 won't. any advice?
thanks!
ok, so since no one tried to help me here, i tried every single thing on my router and it seems that the phone can't handle b+g standards, so i switched to g allone and now i'm able to connect. i hope this will help someone else too.
Nice tip
Hey man,i guess no one had the problem or didnt know what to do,anyway i had a differrent problem,when i was close to my router (no more than 8 meters) my phone connected normaly to the wifi,but once i was in my room which is further away from the router the phone wouldnt connect although it showed the wifi router signal had two bars,i tried your method in switching to g only and it worked ,now i connect to my wifi with no problem,thx for the tip ,hope they fix the issue in mango,cheers.

I have the same problem with my wifi router.
My phone is HTC 7 Throphy.
I have to reset my router every time my phone needs to connect to it.
My router is configured for DHCP.
I noticed that if there is a wireless device connected to my wifi network,
my phone gives that error and cannot connect.
If I try to connect to a wifi network which is secured with a password,
I always get 'Incorrect password' message.
I try reseting my phone with no effect.
I'm still looking for a solution.
Same prob here....

no problem man.
it seems that there are many troubles with wifi on windows phone 7 and many users are complaining. i hope too that mango will fix most of those issues. mango will bring possibility to connect to hidden network.
for other users posting on this topic, i suggest that they try switching to g standard only, becose i too had this incorect password message allways poping up before the switching. it can be done in the router web configuration interface. u get in usualiy by typing 192.168.1.1 in your adress bar.

My router is on g standart only but I still get that error.
well, if you know what you'r doing, you could try different configurations in your router. play with the settings and see if it will work, but again, only if you'r sure you won't screw up anything.
I found a fix.
In my router settings I changed the Chanel from 6 to 10.
I think the problem is that I have too many wireless devices in a small room.
you lucky bastards with wifi connectivity.. i have a pppoe account on my wifi and there is no way for me to connect to it whatsoever.
if you have access to your router settings, you can change briged to routed connection.
for some reason, i can't access router! i tried contacting my ISP, did not want to die waiting for an answer.
but i remember trying to do that before, and not knowing how.
Could you post a link with the instructions, zemljak?

I have this intermittent connection on a netgear wireless router too, its set to use dhcp, and only fix is a reboot of the router.
I think the phone is storing an ip (dhcp assigned) which when you reconnect to your wifi may have been re-assigned (ip lease) to a.n.other device in the meantime.
So, lets say on Monday I obtained 192.168.0.2
didnt access the wifi for a day or so
lease expires (router)
a.n.other device connects, e.g. iPad, obtained 192.168.0.2 via dhcp
then you try and use your wifi on your phone and it doesnt connect.....
so I think it might be storing the ip address, rather than checking for a new one each time it connects, or something similar.
Over a half year I had the same problem. But now I fixed it, by simply change the wlan-key, because in my old key I had letters like ä, ö, ü. That didn´t work. May be this works for you.
FIX!

Hi,
I have Nokia Lumia 800 with Windows Phone 7.5 and also have problems with my home wifi connection. Firstly I had an old pentagram router and couldn't to connect with it, I tried WPA, WPA 2, WEP, WPA 2 mixed or even no security, always had the same problem, shows "network don't respond".
The phone itself connects to other networks, but not my home network.
I thought that it was problem with my router (but every other device had no problems with conenction, ipad, galaxy s, laptops or even TV), so I took another router (techniklab) and I have the same problem.
On both routers in "active clients" I saw the phone when it was trying to connect, logs looks like:
Code:
Aug 20 22:13:31 wlan0: WPA2-AES PSK authentication in progress...
Aug 20 22:13:31 wlan0: A wireless client is associated - 50:2D:1D:E2:8A:87
Aug 20 22:13:31 wlan0: Open and authenticated
Aug 20 22:13:53 wlan0: A wireless client is disassociated - 50:2D:1D:E2:8A:87
Windows on my phone is up to date, router firmware also.
I can add that from couple of days I have Windows 8 (on PC) and it also cannot connect to my router, could it be some problems in new microsoft windows??
Any suggestions?
Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!
OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??
Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?
Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.
This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

I've been having problems trying to connect my friend's Nexus 7 (32Gb) to my home wifi. I tried 4 (yes 4) wireless routers, and it refused to connect to any of them. It would prompt for my (WPA2) login credentials, then spend a few minutes trying to connect, then give up and try another access point. It would mark the AP just tried as "avoided poor internet connection".
The routers I tried were:
- Belkin Play Max N600 HD
- Buffalo WHR-G54S
- Draytek Vigor 2920n
- O2 Broadband wireless box 5
The signal strength from all of them was shown as excellent. I tried the O2 wireless box with WEP encryption instead of WPA2 and that didn't help.
I was able to connect both a Samsung Q330 laptop and a Galaxy S3 to all of these routers, so they all appear to be working fine.
As I'm shortly planning to buy a Nexus 7 I'm keen to understand what sort of problem might stop it connecting to my routers!
Any ideas?

Hi,
I have the same issue and i foud that it is due to the inferior frequency of my router wich is 2.4ghz.

All routers use 2.4 GHz unless they are branded/advertised as being 5 GHz. The Nexus doesn't even support 5 GHz. The warning is more about the actual internet connection anyway. As for removing this warning, you can easily disable it under advanced WiFi settings.

I subsequently acquired my own Nexus 7 and had no problem connecting it all of the routers that my friend's Nexus 7 wouldn't connect to. I'm guessing that I was running a newer ROM. I still have no idea why my friend's unit wouldn't connect
Your friend should return his faulty N7 for a replacement.
If you can access the router, do a reset or reboot, sometimes a refresh would get the "hand shaking" working again, switch to an alternate wireless channel as it could be interference from other nearby routers.
after some research i found this .
and for the "avoid poor internet connection" in the advanced menu ,in 4.1.1 the is no such option in the menu .

Your custom rom is not the same as the OP. There is no option you suggest on a stock rom.

usually the problem is with the router, restart the router,

SOLUTION
Figured it out...go to the WiFi settings, hit the menu key and choose "Advanced", and uncheck "Avoid poor connections".
There are lots of android phones without the above mentioned option(The place where you can uncheck your "Avoid poor connections" )
If you're in that case I've got an alternate for you
1. run command prompt and type ipconfig
2. note down your ip address
3. now what you do is change the last digits after the last point and give the command
ping 192.168.1.xx(changing the last digit or last two digits)
it'll say pinging and BLAH BLAH BLAH
It'll give details about the sent and received packets of data
And also LOST packets
NOTE: If the lost =0( 0 % lost)
4. Then note down the ip address which you've given after the command ping **192.168.1.xx**
if the lost= (100 % lost) or may be some other percentage of lost... it means there is some loss of data packets
so never note down that..... repeat the process 3. changing the last digits of your ip address
5. Now once the lost percentage is 0 %
6. go to settings->Wi-Fi-> And long press the network to which you wanna connect your device
7. Choose modify network
8. Enter the password(If there is any and do not press save)
9. Enable show Advanced options
10. Change the ip settings to static
11. Enter the ip address which you've noted down in steps 3 & 4
12. Enter the noted ip address in the ip address
13. Also Enter the gateway address in the column below which you find from your cmd prompt giving the command ipconfig
14. The network prefix length ,DNS 1 And DNS 2 Will be automatically assigned
15. Now click Save
Thats it .......You're Done
incase if the Avoided poor connection occurs again repeat the steps from 6 till the end giving the same ip address which you've noted down
ENJOY ! ! ! ! !
I've fixed it
Hello.
I fixed this bug, it isn't poor conection... it is an error about dhcp server in the android 4.x
First you need to download and install ipconfig app from aptoide
So you need to try to conect to your network, while it is showing obtaining ip adress, you should go to ipconfig app (be as fast as posssible)
Finally you should find your ip number and your gateway, if you don't, click in refresh.
Now go to settings and long click into your network, so click in advenced settings and change dhcp to static IP, here are the recommended settings:
IP- get in ipconfig
Gateway- it will automatically set, the most used is 192.168.1.1
Prefix- 22 or 24
Subnet mask- 255.255.255.0
Dns1- 8.8.4.4
Dns2- 4.4.4.4 (no need to set)
I wanna develop an app to do it automacally, but I need help... I'm pretty noob, I've got only 14 years old
Edited: Oops, I didn't saw your solution, anyway it doesn't work on all routers cause some routers are set to another ip
I'm glad to help you

but when i went to next i logged into my gmail account and i get this

Expected it is not any Hardware issue, it seems your pb is related to your PW. try desabling it from your router (just a short time for test) or go to a free wifi place to check.
Also keyboard issue, do you use the standard one?
good luck

Had this issue before with a bunch of Samsung phones turns out I had so many devices trying to use the same IP address set up by my router. I had to reset my router and assign each device its own IP address.

May also need to check the routers settings for maximum allowed wireless devices, or maximum dhcp users.

The obvious thing in your router configuration is that connections are being restricted to a list of hardware mac addresses.

The obvious is that jour Nexus 7 is not working properly, I had exactly the same behaviour tested many changes on my wifi settings, teathering from my phone...=> went back to the shop for an exchange and the new one was working perfectly
