It's happening on both routers I've connected to, at home with my Linksys WRT54G and at work where there's a Cisco router that I have no idea what the model number is. It's a university, so I do not manage that network.
I'm having WiFi issues as well. Reflashing didn't seem to help. Wifi works for a while, then stops, can't turn it back on unless I reboot.
Otherwise fantastic ROM, thanks.
