Let me explain my prob.I have been using the Beetle yozan (tera 100u) for the past 3 years in Manipal karnataka, recently i shifted to delhi and have taken a new airtel connection but am using my old modem.Now every time i try to use Torrents i get a blue screen error with the message "IRQL Not Less Or Equal" I had the same problem before also but that time the airtel guys asked me to change the encapsulation setting from RFC 2516 to 2364 and my system stabilized, but when i try to do that now my modem refuses to log on to the server and gives an 721 error. Airtel techs have not been able to help and are suggesting i change my modem is there any way to fix it or will i have to go in for a new modem.My system is Win xp media edition with zonealarm pro and mcafee antivirus
