I am facing some issue with the wifi adapter. I am having the Toshiba Satellite A665-3DV. It is having the Windows 7 64bit sp1 installed in that. The problem happens randomly. I am not able to connect to the internet. I am using NetGear DGN2000 ADSL modem. I tried to establish the connection many of the times but all the times it fails to connect to internet. If I use the Ethernet cable then there is no problem in connecting to the internet. This is very strange. Is anyone of you can provide me some solution for this then it will really be a great help for me.
