Okay, i know there are a couple of similar threads before this, but the ipod i have atm is a brand new ipod touch 4... whenever my ipod autolocks after 2 mins, my wifi disconnects when i unlock it. The wifi icon is still there, but my IM apps like beejive and nimbuzz disconnects. Also when i try to load pages in safari, it says 'safari could not open the page because the server stopped responding' The only way i could connect back is either to renew lease in network settings or wait for 5 minutes for the IM apps to connect to the wifi again... i thought os4.1 says wifi doesnt disconnect when asleep? my push notification is on, and also idle settings for beejive is set at 12 hours. I tried resetting network settings to default but still the same. Anyone facing similar problems? anyone knows how to fix this? and i dont think theres a problem with the router wifi since my laptop doesnt disconnects then..
