Nokia
Inter nets get disconnected

Hi friends can some one solve my problem, is I am using Airtel GPRS {packet data} to connect to internet using Nokia 6300 as modem but since 5 days whenever I connect to net within 3-5 minutes or say after 2-3 pages my net gets disconnected and I have to Re-connect it again to surf

P.S

• Using well since 6 months

• Tried formatting and reinstalling XP

• Installed latest version of PC suite ver 6.86.9.0

• Handset {airtel} network is full towered

• Can make and receive calls with clear voice

I wanted to know is it problem with my handset {nokia 6300}

Or problem with Airtel network

Please help me in solving my problem and ending my frustration
