This motor repair business uses the Telecom (pre-Spark) modem noted above.
The business has three computers - two desktops and a laptop.
Until recently, all was well - the computers were hardwired to the network via the modem, the Canon printer (connected to the main PC) was shared with all PCs. No probs.
Until the main PC crashed and had to be replaced.
Here's the weird thing: Now, all three computers can get online (hard-wired, not wirelessly, via the 2Wire Gateway) just as they did before.
But now they can't see each other!
Note that all three machines have been configured to share in the most free and unobstructed way possible in W7 (without going into a long discourse) via enabling 'Everyone', but they still can't see each other.
Note also that the the usual network configurations have all been done, like Network Discovery, File and Printer Sharing etc etc.
And as I said, each of the three machines are able to freely access the net. They just can't see each other.
Hey, I've done this repeatedly with other networked PCs over many years and had no problems. It's my business.
But this one has me baffled.
I'm now wondering if the antique modem has suddenly developed a fault.
Suggestions welcomed :-)
