Apologies for the double post - as a newbie all posts are manually vetted, and I was caught by the time lag involved.

Further to the wireless problem, I'm now thinking this is only coincidental with the grub change not part of it. As I have discovered wireless availability appears/disappears depending which kernel I choose at boot.

When I boot to kernel 3.0.4 everything is fine; however when I boot to the newer 3.0.4-64 I loose my wireless. Realise "loose" isn't a very helpful term - when in 3.0.4-64, from a prompt I can run
Code:
$ lspci -vnn | grep 14e4
and get a response which identifies the wireless hardware. However, within the gui shell I can only see settings for wired connections. Also (being a laptop) LED wireless indicator is OUT and does not respond to attempts to turn it back on.

From Synaptic I can see the same drives for the wireless card are available for both kernels. Can someone advise where to go/check next?
