A growing thread in Apple’s Discussion forum – “WPA on 2nd Gen 2.1.1″:http://discussions.apple.com/thread.jspa?messageID=8441958#8441958 focussed on a possible problem with how the iPod Touch (2nd Gen) with Firmware 2.1.1 has consistent problem connecting with WIFI routers that is set on using WPA/WPA2 security.
Many Touch owners, like myself, have difficulty connecting or sustaining a connection with the WIFI router that has WPA/WPA2 security activated. I had to downgrade to a less secured WEP connection in-order for the Touch to be online.
Many suggestions were tried – resetting Network setting on the Touch, switching off QoS for some routers etc, but most had less than successful outcomes.
Hopefully there will be a version 2.2 firmware for the Touch when it comes out for the iPhone, and hopefully it will fix this possible WIFI bug.
Do you encounter similar problems?
