I suspect it's a 2920n. IIRC it was black, somewhat curvy and with three
aerials at the back.
Hopefully the firmware bug is fixed/absent in this version....
Hopefully :-/
Google finds the 2820 bug, but not a 2920 bug. Might be a good sign.
ESP packets .. those are the ones that know what data you want before
you ask for it. I think you'll find there's only apochyphal evidence
that those ever get delivered anywhere :-)

I use Netgear at home. They seem to get it pretty much right most of the

So long as you're not planning to send the boys round :-)
At this moment it feels like everything with the probable exception of
OpenVPN is a bit of a mess. Which probably suggests my best options.
