Re: OT: Telenet to terminal server dropping -ubuntu 10 driving

Everyone - thanks for your inputs.
I have found the solution.
I ran my laptop on wired connection for a full day and it didn't drop.
Connected to eth0.
well connection drop is depend on your setting on router but telnet session
was not terminating after it drop.

I uninstalled the wifi module from laptop and used NDIS driver instead.

NDIS driver rocks. acces to the lab thr Wireless is now working perfectly.
