Here's the setup: The office computer is connected to a 2wire 2701HG-B modem/router. Another cat5 cable runs from the router to a hub (or switch) in the shop. The shop computer is connected the the hub. A Trendnet TEW-637AP is also connected to the hub. It broadcasts a wireless signal to the CNC computer. Pretty standard stuff that has worked fine until just recently.
All three computers connect to the internet just fine so the hardware appears to be OK.
None of the three will show any computers when I click "show network computers". It just times out with an error message.
The office computer can communicate with the shop computer. I can change and move files normally. It will let me add network drives.
The shop computer cannot talk to the office.
The CNC can't talk to either and neither can talk to it.
I'm not exactly sure what proceeded the break but I have one suspect. I recently got a Dish Satellite receiver that wanted to be connected to the internet. It was around this time that it went bad so my best theory is that it mixed up the addresses that the router assigns thereby mixing up the Windows network. I don't have a lot of faith in this theory but I thought I should mention it. The only other thing I can think of is the flurry of XP updates that we've had recently.
I've run the network wizard till I'm blue.
Any suggestions would be most appreciated.
