[Gllug] decreasing ping times

[gllug at minty.org]

Every once in a while my adsl modem goes a bit funny.

If I ping it from within the home network, I get ping times that decrease by almost exactly 1 second each time, going from ~16 seconds down to 1, then repeat.

When it happens, it's quite a consistant cycle.  A power down/up normally resolves it, but sometimes it just clears itself.

Any ideas why?

something along the lines of
