Question possible wifi card problem


hi,

i have a dell 1501 run by ubuntu 10.10. everything was working okay. and then the user ran an update. subsequently the wifi has mysteriously stopped working. it connects okay if one plugs it directly into the router but the wifi seems to have just stopped working.

my mini 9 connects fine to the netgear wifi router using wireless.

when i run the system tests i get the errors...
"root could not find def gateway info /proc"
"root could not find default gateway by running route"

is this a hardware problem or a software issue?

how should i proceed?

please advise.


PS,kernel version is 2.6.38-8-generic
here is the output from lspci -v,,,
