I am using a laptop with wireless connection to my Airtel broadband, as well as a PC connected directly. If I leave the connection on for a while without activity, or if I bring the laptop out of standby mode my net stalls and I cannot view any webpage. Once I restart it works perfectly. This is becoming really irritating as I rarely switch my computer off , so every time I return to it I have to restart.I've had this problem from the beginning. The airtel guys have no clue... and have replaced the modem 3 times with no luck...can anyone help!thanks!!
