I have Linksys b router with 1 desktop computer connected via cable, and 2 other desktops and 1 laptop going wireless. The hardwired one works smoothly, no problem. All others have inconsistent Internet access, it is on and off without any regularity. All the computers can see each other all the time, i.e. I can share files and printers NO PROBLEM. All the computers are located on the same floor within 30 feet from each other.
Any ideas?
