A while ago - it didn't seem to do exactly what I want, but I'll check
again.

It's not ppp - it's more like ADSL and straight ethernet from my viewpoint.

Internet connection will just disappear if the weather turns bad (it runs
at approximately 802.11g frequencies, so is affected by precipitation just
like wifi).
