ssh & scp between 3.01ee and other linux OSs on a LAN

[Beartooth]

-- and to judge from ifconfig listing both ath0 and wifi0, I suppose it may well be running both the ethernet cable connection *and* the wireless connection to my router.

Fwiw, something called binky on the panel seems to be saying much the same.

But when I open a terminal and try to ssh between the EeePC and one of the PCs on my LAN, it only rarely makes a connection -- either PC to EeePC or EeePC to PC.

As for scp either direction, that has yet to succeed, ever at all.

Is a double connection worse instead of better than a single one for some reason?

Of course I can detach the cable, or turn off the wireless access offered by the router -- though I don't know whether there are any precautions I ought to take first.

Or do I have some completely different problem??

Footnote 1 : I gather there are GUI front ends for some of this; that's fine, but the plain old CLI will do what I need at present, if it ever once works.

Footnote 2 : I hope I'm in the right forum for the question; my apologies if not.
