The "check cable" message is just a carry-over from pre-wireless.  It 
means that the wireless can't establish a link level connection.  With a 
wired connection, this is equivalent to having a working cable in 
place.  Thus, "check cable."

Some things to try are:

Open up your access point (no encryption, authentication, ESSID is 
broadcast, no MAC filtering) and see if you can connect.  Your security 
exposure is fairly minimal if you only leave it open briefly.

What gets reported if you do a "iwlist eth1 scan"?  If nothing then your 
system isn't even talking to the radio.  If you get a list of APs, then 
some higher level glitch like authentication is causing the problem.

I get the "Determining IP information for eth1...dhclient(4733) is 
already running..." message whenever I switch my laptop from wired to 
wireless.  Just do a "kill 4733" (or whatever PID gets reported in the 
error message) and try it again.

Cheers,
Dave
