WiFi in BKK
 

I happend to notice WiFi wireless LAN connection is partially available in BKK first class lounge.
ESSID is 'cathay' with no WEP key.
WEB browsing is OK.
However, I can not use VPN to the internal network of my office.
In the Wing,Pier,NRT,CDG, I can use network almost seamlessly.
Maybe, BKK service is not for passengers.
