PPPoE Disconnection Wireless ISP Future

[Bikrant Neupane]

I guess there are two timeout conditions, Session-Timeout and Idle timeout. 
You may want to verify both of them. 
We are also running wisp and we had many complains about frequent 
disconnection. Windows machine disconnects (dun client) if network goes down 
for about 40-45 seconds. I could not find anyway to increase the timeout 
value at the client end. I did try with registry settings but that didn't 
help either. Later we choose to use the tango manager pppoe client and so far 
it is working fine.

regards,
bikrant
