This is what I am getting:
=========================================================

=========================================================

Don't be fooled by the  Link Quality:0  Signal level:0 readings.  In another 
hotel up the road I got 30/100 link quality, and got an IP address, but then 
I couldn't connect to the Internet.  On the last hotel (with the readings 
quoted above) I can't for the life of me get an IP address.  What am I doing 
wrong here?

BTW this is what tcpdump reveals:

Have you tried:

# iwconfig wlan0 essid "The Cairngorm Hotel"
# dhcpcd wlan0

?

Do you have Windows installed? Do you get an IP address on Windows?

I did not try specifying the essid manually, given that it is the only essid 
in the vicinity and iwconfig shows that my machine has already associated 
with it.

However, I've tried the dhcpcd wlan0 but it eventually times out.  :(

> Do you have Windows installed? Do you get an IP address on Windows?

No I don't.  This is a Gentoo-only laptop.  But other WinXP machines appear to 
get an IP address and connect happily to the Internet at both hotels.

What else should I try?  Would perhaps dhcpcd -S be needed to get the router 
to assign an IP address?  I do not have much experience with wirelless 
connections because up until now I've been lucky enough to always connect to 
public (and private) WiFi routers effortlessly.

This is a stupid thing to write, and it may not help, but:

Are you running wpa_supplicant?  If so, have you tried stopping it?
