6.10 Edgy Wireless not connecting after travelling and using other networks

[Ronald Bradford]

Hi,

I'm desperately seeking help with my wireless configuration Ubuntu 6.10 
Edgy.  In summary it was working on my home network, but after travel 
which included an attempt to install WPA, and still being able to access 
other wireless connections  I've returned home but am unable to connect. 
A summary of things I've done.

* I can confirm that my wireless in my Lenovo T60 is functioning under 
Windoze and the router is correctly configured, including other devices 
in the household working
* I have reviewed the docs WifiDocs/WiFiHowTo 
(https://help.ubuntu.com/community/WifiDocs/WiFiHowTo), 
WifiDocs/WPAHowTo (https://help.ubuntu.com/community/WifiDocs/WPAHowTo) 
and WifiDocs/WiFiTroubleshooting 
(https://help.ubuntu.com/community/WifiDocs/WiFiTroubleshooting)
* I have removed wpasupplicant, which is what I did to try to get WPA 
working
* Things appear to be configured correctly, it seems to have a problem 
with DHCP discovery, yet it works find for my wired connection
* I have tried harcoding my IP & Gateway to correct settings without 
success.

If somebody can please point me to what I hope is a stupid configuration 
somewhere it would be greatly appreciated. Here is details of my 
configuration I hope will pinpoint a problem
