[Q] Wifi-Mobile Network Connectivity

Ever since the new leak of 2.3.3, the Wi-Fi connection randomly drops.
But I discovered it was because of Mobile Network on. If I turn Mobile Network off, the Wi-Fi connection is immensely stable. Is there a work around this? I would love my Mobile Network & Wi-Fi to be working at the same time.
I'm having the same problems. Thank OP.
Not only do I get this but my gps doesnt even come close to working like it won't even show that its on in the notification bar. Any one know a fix?

ICS Wifi connection possible fix

I've seen this possible fix in another local forum's SGS2 thread. I tried and it seems to work fine so far. I had no problem with wifi connection at office but at home I could barely even stay connected to internet even though it shows connected to wifi. I couldn't even connect to wifi at home before and after doing this my connection is stable now. Please share your own experience after trying this.
Possible fix:
Open phone app and dial *#*#526#*#*
This will load wifi test drivers
Just leave with home button
Turn on wifi
and please let us know if this works for you too

Hot Spot Connection Errors

I noticed when toggling on the mobile hotshot it fails to connect. When it turns off WIFI it doesn't allow enough time for it to completely get shut down before engaging the hot spot so it fails. Turning off wifi first fixes this. Another thing they need to fix.

If you use Hotspot Toggle Widget you must enable and disable through the widget. You'll run into issues if you, for example, enable through widget then disable directly through stock hotspot.

Wifi- unstable connection

This is my second note 3 and it happen with both. Whenever I connect to a wifi I get a notice popping up that my Internet connection is unstable.
Of course when this happens no data transfer happens.
Any thoughts??

I noticed that the unstable connection was an issue when I installed adblock plus. After I uninstalled it the problem went away. So far that's the only resolution I've found.

I've been having the same issue, even from my bed which is about 10 feet from the router. I'm starting to really kick myself for letting myself fall outside of the 14 day return period...
Seems like a bug, I see it occasionally but I never drop any packets or see any latency.. shrugs..
I've been able to fix this issue by booting into stock recovery and wiping cache.

I've noticed it too with Adblock Plus installed. I think, it would constantly tell me that the connection was disabled due to slow network or something along those lines, on multiple different networks, all within 10 feet of the router. I wasn't able to use any apps that use internet other than Chrome today. I uninstalled Adblock Plus and it seems to be fine so far.

[Q] Data Connection to wifi

I'm using a Galaxy S4 from USC (SCH-R970).
4.3.1
Loaded PAC-MAN nightly build dated 11/16/13
All seems to work very well and I'm quite happy with the ROM. There is one glitch I'm having which I can only assume is from the ROM. Whenever I leave my wifi connection and the phone needs to switch to data, it doesn't. It takes a reboot and then all is well. This is what happens when I leave home to go to work. I don't have a wifi connection at work. Going back home doesn't cause any problems. It happily picks up the wifi again.
Other forums have had some suggestions such as toggling wifi on/off (as in airplane mode) etc., none of which seems to work for me. I need to do a reboot to get back to enabling data connection.
Has anyone else noted this? Is this a known issue? Are there any suggestions?
Thx
I have almost the same issue, for me, I randomly lose data connection, and have to reboot to fix it. I DL an app called 3g reconnect and haven't had the problem since. I don't know a real fix but hope that helps
