Not sure if anyone has experienced wifi issues (not specifically DLink related)?
I have been using mobile data a lot at home because of issues on my access points (DLink downstairs, Cisco upstairs and TP Link in the home office).
It just randomly stops sending/receiving data and page loads, downloads, thread paging in Tapatalk, etc... Just time out. I have to disable and re-enable wifi to get it going again. Also finding it a bit slow.
I got fed up and just stuck to Vodacom and attempted wifi again every now and again. Problem persists.
This AM I installed

Seems to be a JB problem, but I never experienced this on my S3 or Note 2 - so dunno.
Sharing this incase someone else has issues.
