Netgear MR814 (B) Router & Linksys WUSB54G (G) Access Point

Am trying to access a Netgear MR814 with a Linksys WUSB54G Network
Adaptor with no luck. The Router works fine with my laptop (using a
Netgear PC Card, and used to work with the now burned out Netgear AP).

I can get a weak signal using the default, but nothing with my network
although it does recognize it. The Linksys support people say it's the
Netgear, and I won't call Netgear because I'm out of warranty on the
support. The Linksys people said there should be a setting (mixed; I
assume that's for both B and G), but there is not such a setting
(although there is on the Linksys side and I do have that set to
mixed).

If anyone know how to get this to work, I'd appreciate the info.

Worst case scenario is that I'll have to upgrade the router to a
Linksys G. I am planning on doing that anyway, just didin't figure on
doing it now.

Thanks,
John
