I rooted my Galaxy Note 2 N7100 yesterday, which is running 4.3 stock Samsung ROM.
I followed this guide (Philz touch, Multitool to de-knox, cf autoroot)
My issue is that the wifi connects okay, but will only work for a couple of minutes before 'hanging'. For example, I can load websites for a few minutes, then it will just be stuck with the loading bar about 1/4 complete and do nothing. There are no errors like 'obtaining IP address' or anything, still says 'connected'.
Turning wifi off and on seems to cure the problem for a few minutes again, so does the app 'Wifi connection fixer', again for a few minutes.
I have tried several different wifi networks with the same issue.
My battery drain seems to be worse as well, could it be a modem issue? I was under the impression that root wouldn't change modem or anything like that?
Edit: I also flashed Dr Ketan wifi patch and this didn't seem to work either.
Edit 2: Oh no, mobile data isnt working at all now! What is going on?
Edit 3: Mobile data back working intermittently but very very slow.
Edit 4: Mobile data very intermittent. Working sometimes and not most of the time. Was fine before root. Something strange is happening.

Any help appreciated.
