Sounds like it needs a firmware update (which is not uncommon with older equipment)
I found VPN & WPC11 issues in the Linksys support FAQ, which is probably the issue - there are other quirks associated with the router, however since it worked fine with the other laptop g card & Linksys acknowledges an issue, that would appear to put the problem area firmly with the WPC11. I'll try the beta drivers tonight & see what happens!
