For the past few months, I've been trying to solve a network problem at a home in Berkeley. The network provides Internet access to 7 computers: 4 Windows laptops, a Windows desktop, a Mac laptop, and a Mac desktop. All except the Windows desktop connect via wifi. ATT DSL is the provider.
After between 1 and roughly 20 days of flawless performance, most of the computers suddenly can't connect and the router seems reluctant to assign IP addresses.
I've swapped out the modem once and the router three times. ATT has troubleshot (without visiting) and they say that the line is fine (and I strongly suspect that they are right).
I'll skip further details and jump to my question:
Is it possible that one of the computers has a defective ethernet card or wifi adapter that brings down the network?
If so, how would I determine which computer might have the problem?
