I used the previous fw 2.0.5 and 2.0.6, even with all the other issues the WiFi was very fast and had no problem connecting to my pc via WiFi.
Since the update the 2.0.7 beta and 2.0.7 final the WiFi does not connect to my PC. The Mede8er does pick up that I have a WiFi signal in the house but fails to connect.
I had it connected once but it was so slow its not even worth it to copy something with a speed of 2 - 5 kb/s. thats slower than a dial up connection in the old days.
