My computers/OS consist of:
-- My laptop with Vista Home Premium
-- Mom's desktop computer with Windows XP Home; has two printers attached and wired directly to the router
-- My desktop with Windows XP Pro; has one printer
And the workgroup name is set to MSHOME on all computers.
I've gotten it partially set up -- My laptop and desktop get along just fine, though I haven't gotten my laptop to connect with the printer (I have an idea what's going on there, though).
However, neither the laptop nor my desktop will show up on Mom's computer, and vice versa. I'm not so concerned with hooking up to her printers, though; I don't think they're Vista-compatible anyway.
Also, my desktop is at the opposite end of the house from the router (which can't really be relocated, because of wiring) and gets pretty spotty reception from it... and as soon as I turn on my PS3 (also connected to the network, and sits between the router and my computer) I lose connection to the network entirely on the desktop.
Would a repeater help solve that? And if so, any suggestions on a brand or anything like that?
