My ISP gave me this Pirelli Discus DRG A125G router/access point.  It
seems to be Linux-based, with some custom ISP firmware.  Sort of nice.
Unfortunately it doesn't play well with N810's power savings:

  mg at laptop$ ping -n ip-of-my-n810
  --- ping statistics ---
  100 packets transmitted, 100 received, 0% packet loss, time 99355ms
  rtt min/avg/max/mdev = 490.189/20743.724/49717.384/14067.338 ms, pipe 39

With a latency of 49 *seconds* you cannot have an ssh session -- it
times out before you can start typing.

If I open an xterm on the N810 and start pinging the AP to keep it from
sleeping, everything is fine.

If I go to the very-well-hidden Connectivity settings -> Connections ->
name of my connection -> Edit -> You cannot edit while connected -> Ok
-> Close -> Close -> Disconnect -> Connectivity settings -> Connections
-> name of my connection -> Edit -> Next -> Next -> Next -> Next ->
Advanced -> Other and change Power savings to On (intermediate)
(*whew*!), then ssh becomes usable.

Just giving some Google juice to the "DRG A125G + N810" combination and
venting some feelings, feel free to ignore this post.

Truth does not demand belief. Scientists do not join hands every Sunday,
singing, 'Yes, gravity is real! I will have faith! I will be strong! I believe
in my heart that what goes up, up, up must come down, down, down. Amen!' If
they did, we would think they were pretty insecure about it. - Dan Barker
