For as long as I've had my gnex I have this problem with Wi-Fi connections. The issue seems somewhat ROM/kernel related. The issue is that WiFi takes an incredibly long time to do anything. Such as the play market where it may take it 2 to 3 minutes after selecting download to actually start. This same problem affects other app usage as well. It does not affect browser usage however. This problem is prevalent almost across the board no matter the ROM/kernel setup. Some ROMs do work great no problems but I do not necessarily like these ROMs. If anyone has any suggestions or knows what I'm talking about and can help me out I would greatly appreciate it.

I am facing a very peculiar issue that makes my mobile internet dysfunctional. Whenever I switch from 2G/3G to WiFi and then switch back to 2G/3G from WiFi, the internet refuses to work unless I restart my phone. Once, the phone is restarted, it works like a charm again till the time I switch to WiFi again. Sometimes though, 2G/3G would not work even if I do not switch to WiFi. Also, rarely, it still may work even as I switch back from WiFi to 2G/3G. This issue has plagued me since a long time and is sometimes accompanied by call drops.
I took my phone to a Samsung Service centre but it wasn't of any use. They do nothing except reflashing the stock rom. It did fix the problem for a while but in an hour or in a day(or in some random time duration) the problem resurfaced. I took my phone to the service centre, just to get this problem fixed. I have tried switching between different modes in settings: GSM/WCDMA/auto etc
I also tried contacting my mobile carrier and got my sim card changed. Therefore, the mobile carrier is not at fault (Internet works flawlessly after I restart, remember?). How do I fix this? It is really irritating to restart the phone every time I need to use the internet. Please help! :-/
Maybe try flashing a different modem. I had various data and call issues on my i9300. After flashing 10 or so different modems I found one from aveuropean carrier worked best. Im in the uk btw

Thanks for replying thedadio!
But I've never flashed a modem before and have no clue which one to choose. Is it same as flashing a custom rom? Also, can I brick my device while flashing modems?
Yes its similar to flashing custom ROM. What ROM are you on and what modem are you on?
McLaren__F1, I am on stock 4.1.2. Also, I just tried flashing DDALJ1 modem (As I'm from India) and Perseus kernel. None of these steps helped me in any way. Still the same issues. :-/
Which is your network provider? I had the similar problems when I was on docomo..nw ported to airtel nd problem solved.
Btw did you try some other np's sim?

I am currently using Airtel (Prepaid). I haven't tried using any other np's sim though..
I have the exact same problem. I am with optus Australia. I tried different modems, different ROMs but all have the same problem. I have sent mine away to be replaced and am still waiting for the new one. Very frustrating problem.

I'm not sure if they'll replace mine. It has been almost 6 months since I bought it..
How do I solve this? Any clue anyone? :|
My Note2 does this sometimes & only fix is a restart.
try soft format may its helpful
Not a fix, but toggling airplane mode on and off does the job for me.
Interestingly this happens to me only when leaving one particular WiFi access point.

i got exatly same proplem, 3g not working after leaving wifi of my workplace, but when im home i have no proplems if i decide leave my home network.
could it be related to radio type wifi has?? my workplace still using old hardware with radiotype of .g and leaving that network "kills" mobile network and i need to reboot phone, but my home network is .n and im not having proplems after leaving it. if its related to wifis radiotype it should be easy for someone to write script which reboot mobile network after leaving those wifi networks.

Doesn't work for me. This problem is strange. :-/
No one has a solution for this problem on XDA?
Did you use the NFC to scan anything by any chance? I don't know if it could be related but my phone started to have issues around the same time I bought some NFC tags and started programming and scanning them.
I still haven't got my replacement phone back yet. But I'll let you know if it still has issues in my problem spots. Than we'll know if the problem was with the phone or just this model.

Nope! I haven't used NFC at all.
Ohh, okay..Eagerly waiting for your response! *Fingers crossed*
Tested replacement phone today and the problem seems to be gone. The signal was actually stronger than all my previous phones.
This issue could be a hardware problem as from what I have searched on the net it seams to affect only a few people. I just hope if I root the phone the problems don't come back.
Maybe you could try send it away for repair if they won't replace it.

Looks like I spoke too soon. The issues are still there. While waiting for my replacement phone I was using an old HTC wildfire and had no issues with the data connection so it must be an issue with this model.
I have been having some connectivity issues and I was wondering if anyone else is experiencing the same thing. It will happen randomly during the day, where I will have full bars of 3g+ but yet when I try to use the browser or any other applications that uses the internet (instagram, FB, etc) nothing will load and eventually time out. Rebooting and turning off 3g/2g/mobile network and back on does nothing. Connectivity seems to come back whenever it feels like it. Ive talked to one of my other friend and she has also experience the same problems on her Note 2 and neither of us has reached the 5gb cap either. Are there any fixes for this?
Have you tried flashing a different ROM to see if that corrects the issue or going back to stock? maybe flashing a different modem my work

Sometmes when I turn on or off the wifi my phone just reboots. I am currently on the stock rom and just rooted. Any idea whats going on here with this? Its really annoying when it does this at times. I hope this isn't a hardware issue.
Reboot typically means kernel panic. If this is new post-root, then try odin back to stock and reset counter with triangle away. If it continues, return the hardware for replacement.

The problem may be related to your Router, which is causing the issues you're experiencing. For example, check this out:

There's a few posts on xda about the issue also. You can search for those if you'd like. .

I dont have a d-link router. I have a linksys router. I get the issue just from toggling wifi on or off. Its not every time but about half the time.
I have some broadband connection issues while using a cuatom ROM. Initially I tough that it is caused by a malfunctioning SIM card, so I changed it with a new one but still issues. I've flashed different Modems - still no luck. Factory reset also done with no effect.
The way it behaves is that after a minute or two of calling the other person stops hearing me, while I still can hear her/him perfectly.
Any idea on how to fix it? Can it be caused by the rom? Or can it be a hardware issue?
