For the past few days, the wireless LAN RTL8187B on my laptop looses connectivity very regularly.
The icon shows 32% connectivity but the data transfer stops. At the same time, another user with a different Wireless is able to connect to wireless LAN.

Also RTL8187B has difficulty in connecting to Wireless Router Netgear. There is no data transfer even though the Wireless LAN router is on the same floor and there is no wall or door in between.

Please suggest
