I have a G2 that is unlocked, rooted, and uses Cyanogenmod. I deactivated Tmobile service, and since the WiFi won't connect. It says obtaining IP and then won't connect.
I have done all the needed router tweaks. That I suspect is not the issue. I believe that the Tmobile allowed me on my Wifi, but had to register with the WAP network each and every time it used it. This would make sense, as when I tried to use programs like GrooveIP and Talkatone, it had extremely poor connection, as if it were making extra IP hops.
What I'd like to know after searching for many hours is - can I use the WiFi on it with no SIM or active service? I had a Nexus One that would do just that, but this G2... no dice.
HELP!
So no one has any ideas? Anything I can check? At all? I'd really like to use the wifi on this device at least...
Sounds weird. Try resetting your router. I noticed sometimes it says obtaining IP adress but doesn't connect, and when I restart the router it works. Just took the SIM out of my phone and it works. T-Mobile has nothing to do with the WiFi...especially since I'm using an AT&T sim in mine.
Have u tried changing the wifi channel?

I think the problem in this one is your router, not your phone, but to make sure, can you try your device on another wifi network? If it connects you should take a look at your router settings. Maybe it won't let a device connect if it's on a lower speed (as phones do not have the highest wifi speeds...)
If you're able, try the phone on another wifi network and let us know if this works..
Mine occasionally hangs at "Obtaining IP from.." also no matter what rom I used and I have active tmo service. I normally either reboot or toggle airplane mode on and off and that will usually solve the problem anytime it isn't router related.

Have a strange problem with my HTC One X:
When I turn on the wifi on my HOX to connect to my homenetwork, the phone throws my network offline, meaning I dont have any internet access on any other device on my network. When I break the connection with my network on my phone, my network comes online in a matter of seconds... Funny thing is that my wife has the same phone as I and with hers everything works as it should be.
Already have send my phone back to HTC, but got it returned today and still gives the same problems?
Anybody experienced the same problem, or anybody any ideas how to solve this?
Thanx
i have exact the same issue, i tried everything you can imagine but no luck so far. I believe it has nothing to do with the settings of my router etc but that its related to the way the HOX handles the connection. Its sooo random sometimes I have internet but no market, sometimes the other way around. and randomly it just kills my whole wifi network soo my laptops etc are disconnected and i can't reconnect untill i reset the router. As a system administrator i just cant accept it! there is no explanation for this!
But i won't give up untill i fixed this problem, even if it means i have to go through another week of sleepless nights! Using a different router IS NOT an option!
Have you tried setting up a MAC address filter on your router? So DHCP will always give you a specific ip address for your phone? Does that still kick everything else off your network?
Very strange that your wife's identical phone doesn't cause it.
Sent from my HTC One X using xda premium
I have tried everything. Changed settings in the router, given a fixed ip address to the HOX, changed the router, put an extra router in my network, tried the neighbours router, it doesnt matter what I do, everytime it throws my network offline.
Before I send it to HTC we established it could be a hardware problem, but when I got it back yesterday, all they have done was updated the software on the phone. When I compared the software version to the other HOX phone, its exactly the same, so all they must have done is the OTA from a couple of weeks ago..
Waiting for a reply from HTC..
I have the same problem. Router is Netcomm 11n. Only plays up on that router. I finally brought a network extender, and connect to that and have had no problems since.
I am unable to connect to my WIFI at home, I have tried everything I can think of, which is quite a bit. All I get is obtaining IP loop and then says poor signal and quits trying, (I have tried sitting right next to the router) My router shows that DHCP has handed the phone an IP, but the phone does not seem to take.
Tried adding a network manually
Tried advanced settings, and giving a static IP address, I can get it to show its connected but can not get any internet, data etc.
Tried the *#0011#
Tried a master reset, and tried to connect to wifi before installing anything.
I am at a loss, would not be a big deal but the 4G at home is sketchy, cuts in and out a bunch, plus for what I paid for the phone the wifi should at least work.
Tmobile tech support is not much help, neither is Samsungs.
Any help is appreciated!

Does your phone's wifi work on other networks? (Coffee shop, neighbor's, etc..)
What type of authentication is your router using? Try disabling authentication and see if it works.
What model is your router? Does it have up to date firmware?

Yes it connects to my work wifi.
WPA/WPA2
Its a Belkin router, not sure of the model off the top of my head, I know its somewhat newer cause it has the N protocol.
I would really suspect the router if I did not have other devices that work fine on the network, 2 kindle fires, 3 laptops, 1 S,Captive, Wii, and Xbox, and my Vibrant worked fine till I got this phone. Not everything is on at the same time, but I am sure that would not matter cause I have never had an issue when it all was connected at the same time.
Have you flashed a kernel lately? I have issues connecting to my router flashing some kernels. Just a thought.

same issue
I have the same issue, but my Wifi wont connect to any network and actually show throughput if I set the wifi power **** to off with the *#0011# menu.
I was stuck on stock roms because akop based (cmx) dont have that service menu.
I recently flashed to Uvalh2 stock rooted and the wifi works as it should for the 1st time ever. I flashed back to ulvem and it needs the 0011 **** again...
my home router is also a belkin with b/g/n, but my wifi never worked anywhere without the menu trick;
ANY help to troubleshoot if this is radio/kernel/rom based or what setting the menu changes so we can possibly set it manually in terminal..
thanks for this thread
Best I can think of real quick is to try different kernels and modems. (Check out the Modem Flasher in dev, makes it really easy)
Sent from my SGH-T999 using xda app-developers app
Just hate the fact I have to try other kernels and modems after paying an arm and a leg for this phone, should not have to.
And seeing I have never done that before it makes me heisatate even more, I am sure I can do it, just that whole what it.
I just dont get why if I give the phone a static IP then it will connect, but can not move data, I went to the *#0011# and was able to ping the router and laptop on the network etc. I am at a loss
Anyone have any other suggestions on this issue???

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.
Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.
I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.
I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.
Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.
PD

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.
OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.
Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.
Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???
I never had problems with my Galaxy note 2 when it came to wifi until I stayed over my mother's house.
My Galaxy Note 2 constantly kept disconnecting, and reconnecting to her router.
I clicked forget network to monitor the signal strength. There was full bars and the signal never got lost.
So I did what a normal user would do. GOOGLE. And I saw A LOT of people experiencing this issue.
Yet there was no solution to the problem! Everyone is hoping to see an update and blah blah.
So I decided to try to figure the problem out myself.
I thought about it. What's different between my mom's optimum wifi vs my Verizon FiOS wifi.
My router has one network name.. Wait my mom has two? Hmmm...
DX20PR.. *disconnects*......... DX20PR 5G *connects*
WALAH! No more disconnecting and reconnecting.
Moral of the Story: If your Galaxy constantly loses wifi signal, check if your router has a '5G' signal, connect to that instead.
Why this works? idfk. But it solved my problem, and hopefully this will solve someone else's problem :good:
If you have AT&T Smart Wifi installed on your phone then that's been known to cause problems also. I had constant wifi connect/disconnect problems until I uninstalled it.
wifi issues set router to use one channel only
I had disconnects a lot as well until I changed my router setting to use only one channel.
I've seen this problem on multiple phones that I've had. A quick restart on the router always fixes it. Lead me to believe it's the router

Make sure you mom's router isn't set to lower then 50 DHCP Address: EX. 192.168.0.50
Sign into the router usually 192.16.0.1 or 192.168.1.1 from web browser. Go to DHCP Setting and make sure you see 192.168.0.XX (XX being the amount of device that can obtain a ip address to get access to internet). If it lower then 20 change to 50 or little higher.
Hope this helps
If my WIFI security is using WPA2 my GN2 will lose internet connectivity after some time of the screen being off. The only way to get it back is by turning off WIFI on my GN2 and turning it back on. I don't have this problem using WEP security in the router. However, using WEP security is less secure and severely limits WIFI speeds (can't use N speeds).
[Updated on 01/29/13]
I just want to provide a follow-up to this. I recently learned about the ARP table in my router which is responsible for mapping the IP address to its MAC address. If my GN2 doesn't access the internet for a certain period of time its IP address is removed from the ARP table and I have to toggle the WIFI on my phone to gain internet access again. I found that manually adding the IP/MAC address of my GN2 to the ARP table solved this problem. In a 24-hour period I've lost internet access 1 time after about 7 hours of inactivity (I was sleeping) and I gained internet access after a few minutes without having to toggle WIFI. I'm only sharing my own personal experience with this issue in the hopes it will help others. Below is the command I used to manually add a static entry into the ARP table of my router (model: Buffalo WZR-HP-G300N, firmware: DD-WRT):
arp -i br0 -s 192.168.0.101 38:AA:3C:85:1F:7C
I have WAP 2 and I don't lose internet connection. Yes I have a small delay when the SN2 wakes up but it connects right away. Go to your wifi setting and hit forget this network and re enter your pass key and see if this might help. You might have another device using the same ip address.

This did the trick for my father-in-law who was in town with is AT&T Galaxy Note II. His wifi kept turning off/on and disconnecting from my router and I couldn't save the network connection. My router is setup with an N network and a B/G network both with WPA2 , and he couldn't connect to either without the issue (everything other wifi device had no problems). I didn't uninstall the "AT&T Smart Wifi" just went into Manage Applications, stopped the services/application it was running and disabled the application. Immediately the phone was able to connect and keep connection with no problems. I didn't need to restart the router or do anything else.

Hey guys,
So all of a sudden, my wifi is searching and not connecting in a campus setting. My Samsung Galaxy Note 10.1 2014 is still connected to the same wifi my Note 4 was. I have tried rebooting, removing battery, shutting off and on data and wifi, and airplane mode. Nothing reconnects it. Also tried forgetting all networks since there are 5 when searching for networks it finds and reconnecting to one, still no dice. It's been 4 hours, still can't reconnect. Any ideas?

Have you tried to forget the network and then ADD it with + Add Wi-Fi network? I actually had an issue playing with a Galaxy note 10.1 2012 edition, I turned my hotspot (sprint note 4) on and named it the same as our current network (was showing how open networks aren't always the network they say and anybody can create a Starbucks-Guest network.... I used starbucks-guest because I didn't want to put my schools on here). The tablet didn't see the network even after reboots, but when I added the network manually it connected right away. Also was this connecting to the same access points or different ones on the other side of campus?
Yep tried forgetting, re-adding the wifi spot and nothing.
I've been having wifi connection issues since day one of getting this phone.
Not sure if I have the same problem.
But at least once a day, it seems the phone can no longer make a connection to my wifi.
The only solution is to either just power off the phone and restart or do what Sprint asked me to do.
Sprint said to try and reset the network connection information by dialing ##72786#
The phone will power off and then restart do some background stuff and then power off again and restart.
Once that is done, all is fine.
I've never had this happen on any other of my Android devices. I even use a static IP with my phone setup.
And yes, I have tried just using the default of DHCP.
I had thought it was my router (Asus RT-AC68U) which transmits both 2.4ghz and 5ghz. I have both setup and I try to use 5ghz the most.
I did upgrade the router software because I was one version behind, but that did not fix anything.
Also, I had a Sprint femocell in my house (provided for free from Sprint) because I had bad signal issues years ago.. But because this phone uses LTE and now it seems the phone comes with built-in WiFi Calling. (Means instead of using the cellular network it will use my network and ISP to make Sprint calls, all voice and text messages come through normally, it's basically a built-in femocell).
I returned that, whoops still in the box, need to get that mailed out fast.
I'm not sure how widespread this issue is, but I suspect it's bigger that just the two of us here. And if I'm in the wrong thread, please let m know.
Thanks
