If there are tests/ > diagnostics to run, perhaps I could poke around a bit & report...? Please file a bug, and include "ifconfig -v wlan0" and "ifconfig -v wlan0 list sta" to see what's changed. Especially since you're in a hotel, especially since they're likely using something old (eg TKIP encryption, ha!) which I definitely have been fiddling with. I have landed some changes in -HEAD over the last few weeks, so it's possible I broke something there. Are you able to boot an older -HEAD and see if it works? -adrian
