[fixed] Mobile networks showing up as being connected but no internet?

original post
i've looked everywhere for a solution to this.. but no luck.. i have a MT3G and have been switching roms here and there.. have had no problems what so ever with mobile networks (2g, 3g, ya know) and i just switched from kings legend rom to cyanogen 4.2.15.1 and noticed that it said it was connected to 3g but when i try using the browser or any app that requires internet it doesn't connect..
so after all that, i decided to switch to super d to see if it was cyanogen being weird on my phone.. and i'm getting the same issue on this one.. (even after i wipe and everything before flashing)
any ideas?

if anyone is curious
I realized that before i started having issues with both of those, i did a restore using mybackuppro.. and this seems to have been causing the issue.. fixed now after i flashed cyan again and haven't restored any apps

Is possible to have this WiFi issue?

Hi!
Well, I have a very weird issue with custom ROMs and WiFi.
The history begins last sunday. I was using GingerDX wich is really great, but I had some problems with it, the most important was not being able to install apps in my SD card.
So, I switched to GingerXperia V22, this is a cool ROM too but I really don't like that my music lags when I turn my screen on. Also, the SE default dialer and Infinity view are bad and slow, but I didn't have the problem with WiFi, until I switched to XGin 6.2
Everything worked OK except for this:

I just realized a terrible and very weird error with this ROM:
I couldn't connect to The WiFi of my mate's office (where Im currently working). But the weirdest thing was the modem worked fine before trying to connect with my Xperia, but after turning the WiFi on, the modem just got busted and didn't work anymore!! So, no internet in the office computers, neither in my iPod, in my mate's smartphone, etc.! It was necessary to turn the modem off and then turning it on, and turning my X8's wifi off to make the modem working properly again.
Weird, huh?
I reflashed, and the error happened again.
So, I flashed back to the ROM I was using before (GingerXperia V22), and now the WiFi is working fine!
Anyone else with that same error or Im the only crazy around here?

I tried kuyaDROID and the same error happened.
I also did a full wipe... And nothing, the WiFi error remains on those two ROMs. So, Im currently using GingerXperia.
So, the question is: Is this really possible? And, is there any solution?

There may be some bug that's overloading it. Also was it the modem or the router? Cuz if it's wifi I would guess its the router but you said modem? I'd just use a different rom that works.

Guess is the router, where the wired networks are connected, it also gives the wireless signal.
As I said, Im sticking with GingerXperia, wich is not causing the error and Im connecting to WiFi with no problems. But I have personal problems with infinity view, SE's dialer and music lagging.
If is about a overloading bug, how could I fix it?
Im using stock kernel, btw.

To tell you the truth, I'm not actually that smart in this, but by overloading I meant that it might be trying to use too much data or something along that line, did it work fine over 3g?

Yeah, I didn't have any problems with 3G.

Don't really have any idea then, I've had problems with mange one device at a time but not fully crashing. Last advice would be that maybe the router has a limit to the number of connected devices it can have and your phone puts it over, try disconnecting one device then connect your phone

I already tried that, and the problem persists.
But this is a good excuse to read and learn eve more, it is a totally new problem for me hehe.
Thanks anyway, for giving suggestions.

I guess I'd try posting in your phones thread and the rom's also, might get better insight into the problem

To further assist you may I ask some questions;
1. What kernel are you using?
2. Have you tried connecting in other Access Point aside from the previous AP you are connecting with?
3. If using custom kernel did you delete all the modules in system/lib/modules?

1. Im in stock kernel.
2. Nope, I didn't try it. I don't have internet in home, but I'd try in my girl's house.
3. same answer than 1.
Thanks for being interested in this curious case.

If your using stock kernel then you shouldn't have to encounter those issues as most roms esp kuyadroid as you mentioned earlier is made for stock rom. I suggest trying into public wifi access and see if you could be able to connect. You have to have two or more access point to test with as router might have different configs than your girls setup.

CM9 by photon team on Bell Atrix - no wifi

I have N_01.77.33P radio flashed on my phone and I've attempted flashing CM9 it. It seems great however wifi is not working.
I can't post this on the original thread (10 posts threshold) but if anyone is facing same issues or if this has been reported already (couldn't find if anyone did), please let me know?
I have Jan/21 version on it.

You sure you installed the one for atrix and not sunfire (photon)?

Unless the name is misleading I'm pretty sure...
I've downloaded this:
alpha5-cm-9.0.0-RC0-Atrix-KANG-signed.zip
UPDATE:
3g/hspa will work no problem. bluetooth seems working as it'll at least turn on.
Did it work on yours?

I am on the same ROM and wifi is working fine

Works fine on my Bell Atrix. Might be a dumb question, but did you re enter your wifi credentials after the flash? What exactly isnt working? You turn on wifi and you cant see any networks? or you cant connect to the internet once you are connected?

You have to reboot the phone after you turn on wifi. This only needs to be done after the initial install.
Once it reboot, wifi should work.

I don't even get to enter wifi credentials, I try to enable it and it says "Powering Wi-Fi on..." and stays there.

Did you do all the proper wipes before and after flash?

You're absolutely right. Guess I skipped this step... Who would figure you'd have to reboot after the first boot lol.
Connected to wifi now!

I had no problems at all with wifi. It worked on my first boot.

[Q] Acer Iconia A500 on 3.2.1 - Wifi problem

Hi...
I had been using my tab for over 4 months without any issues. My wifi has suddenly stopped working (tab gets connected to the wifi but the the icon doesn't turn blue and the network is not up). I had recently updated to 3.2.1 but it was working fine for a few weeks on that too.
I changed my Wifi router security from WEP to WPA and also tried using static IP. I even did a factory reset (apart from the hard and soft resets) and I still have the problem. It is not rooted (and I don't want to do that yet) and since I'm not able to connect to the internet, I can't use any market apps to fix the wifi issue (even if there is one). Appreciate some help on this. Thanks.

This was happening to me all the time pre 3.2.1. Updated, sometimes it still happens but a lot less. I don't have my tab in front of me but I did find a Wifi widget icon. All you do is press it once to turn Wifi off and then again to start it again. You can probably find an APK on Google and install through your computer.

Kjy posted a wifi fix over in his rom. Install it. It was Acer official so I know it will work with stock. Having a similar problem and thinking about installing myself.

Yea but don't you have to be rooted to install that which the OP said he didn't want to do.
I am having wifi signal strength issue with mine as well. I think I am going to sell mine to get something else. It seems like these units are notorious for lie signal strength which sort of defeats the purpose of a tablet. When my phone gets significantly better strength that is bad.
I think it might be because of the metal back cover and a poor antenna.

Should I just go into recovery mode and install the specific file? Can you point me to the location of the fix?
Thanks.

Search this forum for the file... It's not hard to find. You'll need ClockworkMod to install it. Just flash on top of your rom, reset cache and (just to be sure) dalvik cache under advanced...
That actually only solves a part of the problem; the other part is the fairly weak antenna (just replace it, instructions are in this forum). The less intrusive solution is a repeater (~30 euro here in Germany).
Another good lead is to use a better WiFi AP. Cheap ones (particularly with those 10dbm antennas) tend to produce a lot of noise, which in turn triggers the driver bug (which seems to be the root of this evil) more often... this can be so bad it actually makes WiFi completely unusable (happened to me). The only solution to this is to spend a few extra bucks for some good router hardware (I use a Linksys/Cisco router and Huawei repeaters, all of which work fine).

Wifi "connected, but no internet" message

Hey i had a question regarding using wifi at airports and hotels, with roms like pure nexus etc i always have an issue connecting to wifi at airports and hotels and have to turn on dhcp clients under dev settings, after that also it's broken and wifi show "connected but no internet" message. Anyone here who travels a lot and uses wifi at such places ? i'm a pilot so this thing is really important for me. Looking for a rom where this issue isn't present preferably some someone who has been using wifi at airports and hotels regularly. Also when i reverted to stock after unrooting it i'm facing no issues now, but i can't stand the stock rom lol. Thanks in advance.

I had the same issue on the previous two builds of Pure Nexus but when I toggled DHCP Client in Developer Options I was able to connect to airport/hotel wifi and use it too. I didn't have the "Connected, No Internet" afterwards. I carry a USB-OTG drive with a ton of different ROM's and Kernels on it. When this happened to me last week while running the latest version of Pure Nexus, I wiped everything and restored a backup of of AOSiP 4.4 and I didn't have this issue at all. I also restored a backup of the stock MOB30M and it was not present as well. AOSiP 4.4 is the only custom ROM I tried while I was at the airport and my hotel. I haven't had a chance to work on the issue with Pure Nexus again.

Give it a shot. It's worth it if it works for you. I have been at home for the last week so I haven't had a chance to try any other ROM's to see if the issue persists. AOSiP 4.4 was just the only one I tried during that time frame. Hope it works for you too.
If you want to try AOSiP 4.5 here is the link below:
https://www.androidfilehost.com/?fid=24651429356503310
AOSiP 4.4 is here:
https://www.androidfilehost.com/?fid=24588232905720427
I also use Banks GAPPS and have never had any issues. AOSiP is a really nice ROM in my opinion. Lots of customization, good looks and stable with their kernel or any other kernel I have tested with. I personally use B1RCKB1RD Kernel with every ROM.
Good luck and happy flashing. As always, make a backup before hand in TWRP or make sure you have one saved somewhere just in case some goes awry.
