Oh...what I wrote on Linux now seems quite embarrassing...

I wonder how I can find what speeds the on-board wireless adaptor supports (54 or 108). Unfortunately, I do not have the laptop's manual. Could you suggest something?
Many thanks!
PS. I have noticed that PCWorld offers the WGT624 for a very good price under their Collect @ Store system (reserve at the -cheaper- online price and collect at your local store). I popped around this afternoon at my local store and they indeed stock the v4 of the Netgear router. Its online price would perhaps be cheaper than the Linksys ones.
