Can't connect to other Macs thru Wifi, Can thru cable

[VideoBeagle]

A problem has developed on my MBP running Mountain Lion.

I have 3 Macs in my home, the MBP, a G5 power mac, and a Dell Hackentosh. The G5 and Dell are both cable connected to the router. the MBP is usually wifi.

Previously, I had no problems connecting to any of them from any of them, thru file sharing or thru screen sharing.

Lately, I've found I can't connect from the MBP to the other machines thru WiFi. I get can not connect errors, or even it doesn't see them on the network.

However, I have no problems if I plug the ethernet cable into the mbp. Then I can connect in anyway I want.

(I do not know if I can connect TO the mbp from the others when the MBP is on wifi)

Restarting the mbp or other machines have no effect.

Anyone have advice or experience in this?

Just for starters, did you restart your modem and router?

I'm pretty sure I have in the past with this problem...but not in my more recent bouts with it. Should try it tonight though.

What happens if you try to "directly" connect to the computers (Command + K in Finder) and type afp://<<<IP ADDRESS>>> and report back.

I can't recall in the past...last night when I tried it, the whole "last server" field was blank like I'd never used it before (which I have). It was 2 am so i just grabbed the cable for my file transfer rather than testing, but i'll give it a try.
