Hmm, need to setup WEP or WPA-PSK, manually over Wi-Fi
  
   
  +
Actually there is even quicker:
−
Example for WEP:
  
  +
telnet 192.168.42.1
  +
kk

  +
==WEP?==
  +
Apparently possible to setup WEP, or even WPA?

That's the minimum we can do:

# fix bug in /etc/passwd (trailing spaces after /bin/sh)

# redirect root home to /home (where there is already a .bashrc)
  +
sed -i 's#/home/root#/home#' /etc/passwd
  +
# move shell history
  +
mv /.ash_history /home/

# redirect telnet login to /bin/login

Actually there is even quicker:

WEP?

Apparently possible to setup WEP, or even WPA? 

bcmwl addwep 0 1234567890
bcmwl wsec 1

Permanent (! reset wouldn't clean it, maybe flashing from USB?) 

vi /sbin/broadcom_setup.sh
At the end of the create_access_point
Before the print out of success
add the two lines:
-------------
bcmwl addwep 0 1234567890
bcmwl wsec 1

Problem is that it may impact link quality and anyway it's incompatible with a SkyController...

telnet password

That's the minimum we can do: 

telnet 192.168.42.1
# choose a new password

# fix bug in /etc/passwd (trailing spaces after /bin/sh)
sed -i 's/ *$//' /etc/passwd
# redirect root home to /home (where there is already a .bashrc)
sed -i 's#/home/root#/home#' /etc/passwd 
# move shell history

# redirect telnet login to /bin/login
