There are few issues which would have an effect when connecting to
N800 with ssh. It's basically dependent on network latency from AP to

These at least come to my mind:

o wlan_sleep_timeout in N800. If it's low, N800 will go to WLAN
  Power Save Mode more quickly which will increase latency.

o Beacon period an DTIM in AP. The higher they are, more latency there
  will be when N800 is in Power Save Mode.

o Broken APs. I have seen APs which don't support Power Save Mode
  properly and connecting with ssh to N800 usually reveals these kind
  of problems.

You could try disabling wlan_sleep_timeout (ie. setting it to 120000)
to see if that helps. But be aware that it will drain your battery
within few hours.
