I have four computers hooked up to a comcast broadband connection. One day all four computers stopped accessing the internet. Ive gone through and done many things to correct this but with no resolution. Noe, all four computers keep comming up that I am connected but when I go into explorer it times out. I brought in a fith computer to see if it was the internet(comcast) its self but in seconds from connecting it to the network, boom… it worked with no flaws. Has anyone had this experiance? Really need help asap! Thanks guys!!
