Just in the occasional coffee-shop . . .
Just in the occasional coffee-shop . . . my wireless card (DWL-G650) never acquires a DHCP lease via dhcpcd.
In other places it works just fine.
I'm using the madwifi driver, usually without problems. The coffee shops in question are all, of course, in "managed" mode, without WEP or WPA. And what happens is that dhcpcd simply times-out. Doing some debugging, I don't see the usual exchanges happening at all.
What I'm really looking for is some kind of strategy for how to troubleshoot and resolve these problems. Assuming that one is familiar with the command-line .. with wlanconfig, iwconfig, ifconfig (any others?) .. how would one go about getting on-line?
Are there any subtle configuration-parameters that might be important at some coffee-shops?
And... is it reasonable to get "ad hoc" to work?
