I've been having a problem with my iPod Touch's wifi connectivity for the past couple months. It started when I upgraded my router to the Belkin F5D8235-4 N+ v2000 Wireless Router with firmware 2.01.06. What's happening is that I can be using wifi for a while ... then go back later on to use the device, and it'll seem as if I've lost my authentication to the wifi. But if I re-enter my router's key it won't authenticate and reconnect me. If I power-down, then restart my iPod Touch it'll re-authenticate to the router on its own without requiring me to re-enter my router's wifi key ... but it's been a MAJOR annoyance to have to reboot my Touch whenever I want to use wifi. Here's my router security setup: Security Type: WPA-PSK Authentication: WPA-PSK + WPA2-PSK Encryption Type: TKIP+AES And I have my pre-shared-key set. My iPod Touch is running version 3.1.2 (7D11). I haven't jailbroken my device. Any suggestions what might be causing this problem, or how to fix it? I'm ready to chuck my router out the window.
