Hi all you computer techies I need help. Since Tuesday I have not been able to get a wireless connection. I can get a connection with a hard wire connection. On my modem the ethernet light blinks green (instead of being a solid green). When I called comcast I was told to call the home networking line (which costs money). I have unplugged both the modem and the router and have changed out the splitter on the line (was having a problem maintaining a connection to the modem. Any suggestions? It is a netgear modem and a ubee d3.0 router.
