I am in similar situation except that my cable would have to be closer 
to 10 m. :)

The LFS book does not specifically address wireless configuration. If 
you have a non-secure router; i.e. no password required, then the 
configuration is as simple as that described in Ch. 7 for a wired 
network. Instead of, or in addition to, ifconfig.eth0 you would create 
ifconfig.wlan0--or whatever deivice name you give your wireless adapter. 
All else is the same. The LFS bootscripts would bring up your wireless 
adapter too.

If your router is secure and you don't want to use static routing, you 
need to install some things from BLFS. DHCP, for its client, or dhcpcd 
and wpa_supplicant. These packages also have dependencies that need to 
be installed. Additionally, there are some bootscripts from BLFS that 
are required.

This is the first build I have done and used wpa_supplicant and, for me, 
dhcpcd. The combination worked, using the configuration supplied by the 
packages and the BLFS book, right out of the box.

Good luck.
