Yes. When I ran my A/P in 802.11g mode with WPA, after I disconnected the 770 from the WLAN (either intentional or accidental) I would /never/ be able to reconnect immediately. It would always take a "Connect"/"Disconnect"/"Connect" cycle to get connectivity back again.

When I dropped the WLAN down to 802.11g/WEP128, this problem disappeared and a reconnect would always work (much more quickly, as well).

It's almost as though some part of the WPA system on the 770 doesn't shutdown properly the first time it disconnects, requiring a disconnect/connect cycle in order for it to get back into a state where it can work again.

I verified this, time and again, with the 770 literally inches from the AP (Belkin AP/RE box with DHCP passthough to the local IpCop server). As mentioned above, the problems totally went away when I reverted to WEP128.
