My wifi on my GS2 has been pretty much flawless since I bought it in July. I have my home router and works router configured in, and when i get into work, it works seamlessly, and likewise when i arrive back home, reconnecting and working as expected. However, this week I've been getting problems with this. When I arrive to the "other" location (eg. into work from home, or vice versa) then the wifi automatically gets picked up normally to which ever router, but I cannot connect to the internet even though it all looks to all intents and purposes to be connected normally in the settings. It only connects to the internet if I reboot the device. This was never occurring for the first 6 weeks or so, but has only started happening this week. First time it happened I just thought it was one of those things, but now its a regular occurrence. I've even tried deleting and re-scanning for the routers, but that didnt work. It HAS to have a reboot to connect to the net after a router change. Once connected it will be fine all day until I go home, then I have to reboot again. Any ideas what has gone wrong?
