Just tested. Every time when I choose "TKIP+CCMP (AES)" for WPA algorithm in Wireless AP security, it just crashes with no any wired and wireless connectivities. But when I choose "CCMP-128 (AES)" instead, it just works fine. So there must be something very wrong in WPA algorithm inside wireless AP engine. Need to be fixed. "TKIP+CCMP (AES)" just works fine in r40274 and before.
Languages of WebGUI other than English do not affect any issues. Wifi seems a little bit better, but I see SFE is disabled by default now.
I think ttraff daemon should be disabled by default. And hope the issue of SFE would completely be solved one day.
