[Q] Cm7, Incredikernel, Wifi Fails To Connect After Reboot? - Droid Incredible Q&A, Help & Troubleshooting

Looking for any ideas...
When I activate WiFi near a known network, it starts to connect, holds at obtaining an ip address, the disconnects and restarts the connection process.
Happens on multiple WiFi access points, home, work, hotel. Rebooted my home router in the hopes that it was coincidence, but it did not help. Wife's Facinate and iPad, and both of our work laptops (Windows7) connect to the home network just fine.
Running CM7 Nightly 258
11/14 Incredikernel, downgraded to the unofficial 11/04 and the official 10/8. Even tried the stock CM7 kernel.
Was running the 08.08 radio, switched to the 07.07, but still have the issue.
WiFi works after a wipe and reinstall untill I reboot, then this starts.

My droid pro did that on cm7 for a while. It would connect if I went to the WiFi settings screen though. Have you tried going to WiFi settings while its in this connecting loop?

Unfortunately yes. I have turned on wifi from the notification widget and from inside settings and receive the same result, no connection and a big battery drain.

Fixed it over the weekend. In case others have problems with AT&T U-Verse 2Wire routers, the change I made that resolved it was to switch from the router default wireless security of WPA to WPA/WPA2...

desire hd (Revolution) finds router slowly

Hi!
I am experiencing a strange problem with my new DHD. At first when I bought it, it connected to my home wireless router in an instance. Even after flashing the stock rom to Revolution. But in the past few days it takes at least 20-30 seconds to connect to the router when I enable the wifi through widget.
If I enter wifi settings, it connects right away.
Any solution for this?
thanks
EDIT: I flashed LeeDroid 1.5.1 today, and I still have this issue. When I turn on Wifi through a widget, it turns on, but it does not connect to my router, well at least not until a good 30 seconds. But if I go into wifi settings, it shows my router as not in range for a moment, and after that it connects to it right away.
I have already tried to forget and re-set my home network settings, restart phone and router, it did not help.
Anybody experienced anything like this?
Thanks
So really nobody?

[Q] CM 7 final - 3 issues

I started using cm7 final the day after it released. Work great for the most part. I know the navigation is messed up a bit and see that it may be fixed in nightly 54 and it sounds like FB is having issues too, but that the board knows about that.
I have read some of the wifi issues but don't see any elaboration on what the problems are exactly. So for me. @ home I have no problem accessing wifi and connecting (WPA2). HOWEVER, at a couple other sites, one running a d-link 825 WPA2, it acts as though it is going to connect, the phone says it is getting an IP address, then it cycles and starts over to searching, found, getting IP. It jut keeps cycling. My home wifi is a d-link 655 and like I said no issues. Anyone know if there is a quick fix or is this a greater problem?
If you have an answer, great, if not I hope this helps someone.

changing the channel freq may help, the wifi issue thats spread through the forums is no matter what they cant connect to any wifi,and the fix for that is getting the Tiwlan.ini from cm 6.1.1 and pushing it to cm7 fixes wifi issue, but since you are able to connect to home wifi, and not others changing the freq channel to 11 or along those lines could fix your problem

I flashed nightly 54 and lost wifi again, as with all cm 7 releases. I pushed the cm 6.1.1 tiwlan.ini file and it still wouldn't work, so I connected to mobile network first, then I turned on wifi and it connected. This method might help you.
As for the issue I have with the cm 7 releases, I can usually connect to wifi, but I get no data moving in or out with wifi and no connection to google servers (wifi icon turning green from grey in status bar) so no internet on any app or browser or market, etc.

You need to install the nightly 45 or 54 since WiFi drivers were rebuilt. Also, check that your wireless router isn't doing any kind of special speed boosting to the g standard. Lastly, try forgetting your connection and re-establish it.

WIFI connection issue

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.

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???

Galaxy Note 2 Wifi 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.
I have the same problem. Need help too.

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.

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 ???

Cannot connect to WiFi

Is anyone else having issues connecting to wifi? When I try to connect to wifi at my house, I get a pop-up error saying "AP currently not in use. Internet connection slow." If I click retry, it comes up again. If I click cancel, it says "Failed to obtain IP" and is not connected.
I have tried restarting my model/router with no luck. My Note 3, laptop, and other devices have no problem connecting to this wifi network...
I had a problem with wifi,but sounds different then your issue.Mine would just disable after obtaining ip.Samsung rep at best buy reflashed phone.That saved all data and apps.AND,it fixed wifi.If you can't work thru your issue,go to best buy or att store and get it reflashed.Cant hurt.
Good luck.

No go for me I just Got my N4 from Verizon last monday and having the same issue u had. I changed my encryption from wep to wap and still same problem. Ima go to a verizon store and see if the "reflash" the phone like some suggest here. Might help my problem
Hi all,
I also experience the same issue from time to time. I have this happen on both my home network (WPA2-Personal) and work (WPA2-Enterprise). My fix is to either reboot the phone or activate Airplane Mode for about 20 seconds and then disable Airplane Mode. After doing that, wifi picks right up for me. YMMV.
I can try to get the exact error log messages from our networking technician at work if it would be helpful to anyone.
Out of curiosity, do any of you have other peripherals connected at the time you experience the issue (Pebble Watch, etc.)?
Same issue
With my GN4, I can connect to my home WIFI no problem and my GF's WIFI no problem but when I go to my Dad's, I CANNOT connect to his WIFI (Netgear WTG624v3) but both of my sisters with a Samsung Tab 3 and Samsung S4 CAN connect to my Dad's WIFI. It's really aggravating. Basically, when I try to connect, it says "connecting" "saved" Then it says "scanning", and says "connecting" "saved" again and again ..... But never connects.
I have tried changing just about every WIFI setting on his router including resetting the router. Tried removing the encryption making an "Open" network and STILL can't connect... and tried every encryption type provided and still nothing. I set the dynamic address range from .4 to .254 (on router) so I could try connecting with a static address to 192.168.1.2 / .3 and still nothing. I tried removing my GN4 browser cache, and setting it to airplane mode(20 secs)... nothing.
I'm at a loss.. given that both of my sisters with two different devices can connect to my Dad's WIFI but I can't with my GN4? But I can connect my GN4 to other WIFI networks, no prob.
UPDATE: Next, I will try downgrading the firmware version on the router to an earlier version. Hopefully, that's the solution. I will report my findings here.
Downgrading or using an older Firmware version for this Netgear WTG624v3 router DID THE TRICK!
If anyone else is having the inability to log into a WIFI router, try installing an older router Firmware version. I got the idea from here:
