Another odd symptom that I just noticed tonight:

If I open up an xterminal on the N800 and ssh *out* to another machine (Computer 1), then ssh back *in* from a different box (Computer 2), as follows:

Computer 1 <----- N800 <----- Computer 2

The connection between Computer 2 and the N800 lags as before. The outgoing SSH connection from the N800 to Computer 1 is fine.

Now here's the odd part: if the Comp2 -> N800 connection lags, all I need to do is type a few characters into the N800 ---> Computer 1 ssh session and everything de-lags itself.

It's almost as though the unit is going into some sort of low-activity power-saving mode... only I've checked and my WLAN inactivity timeout is set to unlimited.

Very odd.
