Hi all, I have an iPhone 4S and I'm suddenly having problems with the WiFi connection on it. Although my WiFi at home is connected and my laptops and wife's phone work absolutely fine, I suddenly found Facebook and eBay apps were starting to timeout, and then Chrome started to do the same and now I find I keep having to restart my phone to get it to work on the WiFi which will last for 20mins or so and then just stop working even though the WiFi connection is still strong on the phone and my laptops continue to work fine. I've tried resetting my router and deleting all the associated devices and re-pairing the ones I still use, but it's still doing the same thing. It hasn't been dropped, I've never got it wet, and I'm pretty sure I haven't had any updates recently. I can't understand why it's suddenly playing up. Any ideas?
