Windows ME Wireless stopped working

I am trying to fix my father-in-law's Windows ME NEC PC. He uses it=20
infrequently and only for an occasional email and browsing. A couple of=20
weeks ago the wireless LAN failed. On boot up we see a message which =
says=20
that the ATERM wireless LAN card cannot be found. I ran the diagnostics=20
package (everything in Japanese I should add) and saw nothing wrong.=20
Control Panel also showed the card to be installed OK in the slot. I =
could=20
stop the card and reinsert and all was well it seemed.

On Saturday I bought a new card - an upgrade to a g version as well as b =
-=20
for future upgrade of the wireless base station. The card installed fine =

(Buffalo) and the drivers also installed from the CD with no hassle. =
Then I=20
tried the second half of the install and began to hit problems. For some =

reason there is no IP address being set in the card. As the card has no =
IP=20
address set then of course we cannot get any communication working at =
all.

Does anyone have any ideas...seems like an underlying problem rather =
than=20
either of the cards now as far as I can see...
do I need to set up ME again or rebuild the network or something similar =
?
