  I'm trying to connect to a Belkin N150 wireless router with a netbook
running Gentoo.  I know that that the netbook's wireless works, because
I've surfed the web at a Toronto Public Library free wifi hotspot.  My
home setup.  I have an ST546 4-port ADSL modem/router connected to my
ISP.  My home LAN is 192.168.123.248/29 (range from .248 to .255).  The
external interface is 192.168.123.252/29, and internally it's
192.168.2.1/24.  The Belkin's yellow ethernet port is connected to the
ST546.  For testing, my netbook is connected to the N150 via the wired
jack as 192.168.2.2/24.

The wired setup works perfectly; I can ssh from the netbook to the PC,
and from the PC to the netbook.  Both machines can surf the web, etc.
My problem is the wireless setup.

I've manually set up the WPA-PSK as per the instructions.  I've enabled
DHCP with range of 1 address 192.168.2.9, since I only expect the one
client.  I've enabled b/g/n (my netbook is b/g). but I'll cut it down to
g-only once I figure things out.  For my passphrase I've enabled all
printable characters from ascii 32 to 126.  I've turned off the Belkin's
firewall and netbook's firewall while testing.  No difference.  I've
changed the essid to "linksys1234" to confuse the enemy. It shows up in
a wlan0 scan like so...

  My startup script is similar to the successful script I ran at the
library hotspot.  It goes like so...

#!/bin/bash
sudo /sbin/rmmod ath5k
sudo /sbin/modprobe ath5k
sudo /etc/init.d/net.wlan0 restart
sudo /sbin/ifconfig wlan0 up
sudo /sbin/iwconfig wlan0 essid any channel auto
sudo /usr/bin/killall -3 wpa_supplicant
sudo /usr/sbin/wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf.home
sudo /sbin/dhcpcd -C resolv.conf -C mtu wlan0

When I run it, dhcpcd fails like so...

wlan0: dhcpcd 4.0.15 starting
wlan0: waiting for carrier
wlan0: timed out

The config file /etc/wpa_supplicant.conf.home (generated with the help
of wpa_passphrase) contains...

network={
scan_ssid=1
  #psk=63 character gobbledygook passphrase
  psk=a long series of hex numbers
}

To generate a gobbledygook passphrase, I use...
head -c 2048 /dev/urandom | tr -dc \ -~ | head -c 63
