The win-CE device provides next to nothing regarding helpful logs, but I know that it said "connected" at various occasions without any link being active. Also, it seems DHCP leases are not verified, instead the remaining lease time being taken for granted. The only thing I can present are the following link-level messages from an unsuccessful attempt using "r8712u" (sorry for the overlong lines): 2011-04-30_03:18:07 + exec /command/chpst -v -m 11333000
