Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument.

If I only knew what to do with them. ;-/ It seems like my goal would be to set up a brdge, or perhaps (according to some of the things I read) routing with NAT, and to set up the netbook as a DHCP server for the wireless network. Am I thinking in the right direction, there? > RF-kill > is sometimes in hardware (physical switch) and sometimes in > software (package rfkill is available starting in Wheezy). Would the rfkill package be useful to install if the messages I get about rfkill include "hard blocked"? > -dsr- And, something I keep wondering about, would ad hoc mode be a good alternative to setting up an access point? I seem to remember using that, perhaps in addition to sharing, on old Macs some fifteen our so years ago. -- Joel Rees One of these days I'll get someone to pay me to design a language that combines the best of Forth and C. Then I'll be able to leap wide instruction sets with a single #ifdef, run faster than a speeding infinite loop with a #define, and stop all integer size bugs with a bare cast.
