I get this connection drop several times an hour, at office up to
20x/hour, with current Ubuntu Kernel + Backports wifi even at home,
before only at the office. Wifi connection recovers eventually, but
breaks VM and often even VPN connections.
Does anyone else see this? Further info needed?

I'm the only one with an issue, everyone else uses windoz with intel
wifi and their connection remains solid.

20x per hour? it mean each 3 mints. Hmm... looks like scan interval of
wpa_supplicant.
Is it possible to change time to live setting of access point?
