Connected to wifi but no internet acsess.

I am currently using CM7. I was previously using leedroid. One night my internet suddenly stopped working. I was conected but i couldnt use it. So i switched roms thinking that was the problem but no change. The wifi works fine on my moms laptop and my dads iphone, but not on my inspire. If i disconnect from wifi, then reconnect it will work for a couple of minnutes then suddenly stop working. Any ideas on what is wrong? It has been doing this for days and its really annoying. Thanks
(Sorry if this is a duplicate topic i had to type this fast before the internet stopee working, and didnt have time to look)

Just curious. Even though other devices can sign on to router, have you tried resetting it. Sometimes they have an ip conflict and resetting refreshes the ip tables.

Yeah I would try resetting the router if you haven't already. I know I have had some connection issues before and it was caused by the router. My computer would work just fine, but my phone wouldn't connect.

It worked. Thanks soo much. I should have tried that in the first place.

The router is probably bad. I sell them at work and they go bad quite often.

I agree, they often fail. I use only linksys routers now and I still have to reset it every now and then.

Its not just at home.. its where ever i try to connect to wifi i realized recently. It is also a very new router

I'm having the same problem with mine. I'm running ARHD 6.3.3 never had the problem with Cyanogen. Is there anything I can do about the wicked not really connecting? I'm running Juice Defender, but I've been having this problem before I installed it.

I had same problem with cm7. Heres what I did - phone- wifi serttings, go to your router connection and press forget. Then I restarted phone, PC, router. Back to phone, wifi settings and re-entered router code, extra. Sounds odd but it worked for me

That happens a lot to me, too. I do believe it's the phone. My room is across the house from the WiFi modem, and my sister's is even further. Her phone catches the signal when mine doesn't. I would like to know the solution, too, if there is one.

Still not working. An app maybe?
I have tried everything.. nothing is working. Its not just at home its everywhere i go. Only thing i could think that would cause this is an app maybe? Is there an app that is known to stop the wifi from working? It has to be something like that. If its not i guess my phone just randomly broke.

So, I had this issue too. I bought and installed an new digitizer (again :/ ) but the tape/adhesive didn't get to me until 3 days after the digitizer. By time I got the tape/adhesive (I temporarily used electric tape on the 4 corners til then) I had gotten a ROM up and running. I took apart the phone, to put the tape/adhesive on the LCD (it was a replaced also) and on the digi. When I put the phone back together, the wifi would work, but no internet. I tried it with 3 different routers and the only fix was to reflash the ROM/a new ROM. This was like 3 days ago. Today I wanted to fiddle with the volume rocker to try and get my volume up working again.... well the same thing happened when I put the phone back together and booted up, wifi connects, but no internet, reflashing the ROM/a new ROM, fixed it. I think there's like something with the phone that 'detects' when it's taken apart, and like does something to the ROM. My Tapatalk accounts got logged out also. I did, both times, also try wiping caches to no avail. Also tried turning wifi off, forgetting the network, and then restarting.... to no avail. The ONLY fix for the wifi each time was to reflash the ROM Maybe someone else could try to recreate this, see if it's only me or not.

I finally found out how to fix it. It turns out I had wifi settings backed up from a diferent rom in titanium backup for some reason. I reverted back to my stock back up, cleared all my titanium backup stuff out, then re-flashed my rom. So thank you guys for all the help. Hope this helps you guys fix you problems.

[Q] Connection Optimizer randomly crashing. Anyone else?

So today, the Sprint Connection Optimizer (which I dont use) has randomly started to crash, especially when I turn on my phone. I switched to ART runtime yesterday but saw no problems all day, just started this morning (I suppose it could be due to ART). Anyone else having this issue? Perhaps I turned off something I shouldnt have in the application manager but I really havent touched the phone this morning.

Same here. I'm still on Dalvik and it didn't happen until I actually connected and saved a WiFi AP. Anyone else having this problem since CF-Root + Xposed?

For me, it seems to happen when it grabs a new connection. If I join a new wifi network, itll crash a few times. If I jump back to LTE, same. Back on my home wifi, crashes. Get a phone call where it goes back to LTE then back to wifi, crashes.
Pissing me off b/c I have it disabled but I cant freeze the damn app.

It is ART. I had the same problem. I switched back and turned the all the animations to off and it seems way faster than with ART on. No more connection failures.

Same. I switched back today. No more errors.

Nexus 5 WiFi problem

Hi guys, I am having a strange problem with my nexus 5, or I should say my Wife's Nexus 5. Right what is happening is that when my wife's phone is connected to a WiFi network it does not receive calls. My phone is identical and has no problems at all. The phone has been back to where we bought it from for repair twice and they finally gave us a brand new phone. After getting home and restoring my wife's phone it has the same problem. Both phones are stock and updated to 4.4.4 . I have checked the settings and as far as I can see they are identical. If I reboot the phone it will ring with WiFi on but after a couple of minutes the problem returns.
Now I would guess that an app is causing the problem but I have tried uninstalling and re installing most of her apps but still can't solve this. I have spent ages on the phone to our provider (T-Mobile UK) tried my sim in her phone but still have the same problem. Is there any type of diagnostic software or app I can run to try and pin point the problem?
The phone has been factory reset but still got the same problem! Bearing in mind the phone is brand new and has the same problem as the old one its got to be an app hasn't it, but how to work out which one
Thanks in advance

Well after an evening of uninstalling and re-installing apps and resetting it seems to have cured itself. I am sure it was something to do with the recent system update, as the problem only started recently. The phone is just over 6 months old and we have had no problems until this. Still fingers crossed it seems ok now.

Hi, i'm having the same problem!! When on wifi sometimes calls get through but most of the time it blocks them, I also thought it had to be something about an app but i even booted the phone into safemode which disables all 3rd party apps and the issue was still there. Where you being able to narrow it down to something in particular??
EDIT: Nevermind, i think i found a thread with the solution.

I should have updated ages ago, the problem was in fact being caused by the sim card. Dont know why it suddenly started playing up but it coincided with the software update to 4.4.4 But my phone was identical and had no problem and my wifes did. Compared to hers my sim was relatively new we eventually ordered a replacement sim and there has been no problem since
Sorry I could not be any more help

[Q] Nexus 5 WiFi issue

Hello everyone.
So, the wifi problem on my N5 goes back some time ago; it happened for the first time about 2 weeks after i got it, middle november i'd say:
i always keep my wifi connected while at home and sometimes it just refuses to send data anymore. The signal bar doesn't drop, but the data just stops working. I don't remember what i did the first time it happened, but it just started working as intented after a few days.(I was on 4.4.4 back then).
Now I'm on 5.0.1 and it had been working right for some time, until 2 days ago i unplugged my router then plugged it back it. Later that day I noticed the issue is back. I have absolutely no idea what to do about it and it is irritating as hell.
Did any of you guys experience this before? If so, how did you fix it?
Also, is it possible that this is a driver issue on the phone side? All my other devices work just fine on wireless.
Thanks!

you may also try forgetting your network and re-logging back in. also check the wifi frequency band and of course rebooting your router can’t hurt.

I tried all that but with no success. I think the router might be the issue since it does have some glitches where it loses connectivity and it fixes after a reboot. I'll try with another router and report after.

I have done a full factory reset on my phone due to this issue, and it still happens. It doesn't just happen at home either, it happens everywhere I go. I am assuming at this point that it is a bug in 5.0/5.0.1 and hopefully it will be fixed in 5.0.2 (if the N5 ever see's this update).
If anyone has had any luck with this bug, please let me know.

I'm having the same issues. I'm now on my 4th router in as many months and I can't figure this out after testing just about every possible configuration of channels, frequencies and settings. We have about 10 devices connected in my home and the Nexus 5 is the only device with this problem. I'm at the point now that I just use LTE at home.

Yeah it's a 5.0.1 issue, if you've found your way to XDA you should try a custom ROM. Most are branched from the aosp 5.0.2 commits.

Did Lollipop rid the wifi options of "wifi optimization" and "avoid poor connections?" I used to keep those options unchecked for a more stable wifi connection.

But I had this same problem on 4.4.4 for a little while, that's why I was inclined to think it was something to do with my router.

Ahhh okay, yeah it very well could be.
I just had to replace my logic board due to faulty wifi, I got the always 'WiFi turning on' bug.

That setting checkbox was missing in advanced wifi settings since 5.0 (and the option was forced to "on")
According to this post this has been fixed in 5.0.2:

[Q] Data once lost wont re-connect

i am currently using Resurrection Remix 5.0.2 but was using cm12 nightlys before. The problem is that
the data connection is good but once i loose the connection there is an exclamation mark next to the
signal bar so i presume thats the data lost. It then wont connect again untill i reboot the phone.I have tried
switching on and off data but still no joy..This never happened on kitkat. I thought the problem was CM
related hence why i tried the RR rom but exactly the same is happening. Someone sugested that it could be
the sim card but im not so sure as it works fine before lollipop.I surely can't be the only one experiencing
this? but by the same token i can't find any info on it either ..maybe says something!!
Hope someone can help as i want to stay on lollipop i do like it, maybe the official release will sort it out.
Thank you

It's a ROM issue (radio.img). I was facing same problem on earlier builds of BlissPop ROM, but not no issues..
If you are getting exclamation mark in 2 or more ROMs, then there is problem with your sim-card or the network operator.
I suggest you to contact your concerned network operator and take his help for the same. (If you are facing same issue on 2 or more ROMs, try out Stock ROM CM11s)

Thank you for your reply, so would it be possible to flash a modem from kitkat or would there be compatibility issues with that?

did you check your network type and apn settings

So here is the latest update. I replaced the sim card on Saturday, the problem is is still there. I checked me APN settings they are three UK so that's ok. I've tried cm12,resurrection, blispop and now I'm on sabermod. I'm thinking this oneplus doesn't like lollipop, looks like I will have to revert to kitkat for just now until the official release comes out but I can't see that fixing the problem either as I don't seem to see anyone else with this problem.
Thank you for your help folks

I'm also with Three and have lost my data connection. They replaced the sim on Tuesday and I'm sure it worked until the old number swapped to the new sim. I have a 321 simcard on order and I'll try that once it arrives. My phone is still running Kitkat.

I had no problems with kitkat, if it lost the connection it automatically connected again when I was back in an area with a signal. But this has got me beat, a new sim card and too many roms to count but still the same problem. I am a lorry driver and cover the whole of Scotland and signal is patchy at best and it's annoying to find out later on in the day that data was off and you didn't receive any messages or emails.. Some of them important..

I have exactly the same problem.
I'm from Spain.
I've discovered that if i set network type to LTE it seems to work right.
Today I've moved from blisspop to temasek.
The 3g reconnect doesn't work, as always.
I turn data and wifi off when I sleep so tomorrow I will confirm if LTE works also with temasek.

my connection has always been set on LTE but never makes any difference
At the weekend I installed the official OxygenOs, I have been driving all day and had to reboot the phone 4 times because of this problem, I did half wish that when an official release came it would maybe sort out the problem but no joy. So I can only think it's to do with the oneplus. I'm at a loss now and seriously don't want to go back to kitkat but it looks like this will be the only solution to the problem..

I've tested this night again and if I set network to LTE.
The test I've done is.
- Turn off data and wifi before to sleep.
- Turn off only data when I woke up.
The connection was successful almost inmediately.

Greetings. I ran into similar issue with the CM12s update.
Once I lose the mobile signal for whatever reason, the data connection is not restored. Only way to regain it, is by restarting the phone (haven't tested airplane mode). Sometimes even if I leave WiFi on for long time (overnight), I will not have data connection after turning off the WiFi. I use HSPA connection only, not LTE.
I can not recall having this issue on KitKat. Issue was on the first CM12s update and remains on the second one, both were installed clean, so clean install of the ROM will not fix it. I am not using any custom ROMs or kernels, only TWRP recovery.
Has anyone had such issue and maybe found a solution to this?

Did you ever get this sorted? I've been having this issue, luckily I always have Wi-Fi at home/uni but there are times when it just won't find a Data connection. This happened right after the CM12 update :/

Well decided to a bit of searching, if you go into Settings -> Mobile Network Settings -> Network Operators and manually choose the network rather than the Auto Search option, it seems to have worked for me for the time being.

I am on the same boat as OP. The problems started after updating to Lollipop.
If anyone has found a solution, please let me know. I read about someone installing a 44S modem, but I'm unsure if this will permanently change system files (I wouldn't want it to) and I'm therefore hesitant.
