Behdel,   Power off your ISP modem/router and your wireless router(if any). Wait 30 seconds, then power on the ISP modem/router. Wait 15 seconds, then power on the wireles router(if any).   Restart your computer and try connect.   What happens?     Rick
Hi; I am using a wireless connection with NEGEAR. My PC was working fine until 3 nights ago, wireless internet access , no issue. A couple nights ago, could no longer connect to internet, even though it was connected to my home network. Any ideas why? Thanks
