Hello I am a new user of linksys and cable.I formerly had dsl with two pc's and a laptop working with no trouble. I moved and dsl is not avail. I now have comcast cable with a wrt54g. every thing was working fine until a week ago. I can only connect through the rca cable modem. when I try the router I get no connection.I have uninstalled Norton, disabled the fire wall,disabled all spyware(microsoft beta and spybot),tried a new router,wrt54g,reinstalled software and still the same. I also did the 192.168.1.1 thing it only works with cable modem.When linksys is inline I get a limited or no connective warning.The system wasworking fine for about 5 months.I believe it started getting screwy around the time I upgraded the Norton to System works 2006. please help my kids have taken over my pc.
