"I tried the latest (8/03) Ralink drivers on a Belkin N1 Wireless ExpressCard Model F5D8071 which I believe uses the Ralink RT2860T (per this page) chipset but I am having no luck.
(FYI - another reader said that N1 card uses the RT2890T Chipset, not the RT2860 (PCI/mPCI/CardBus) or RT2870 (USB) that RAlink posted drivers for. Maybe Belkin Tech Support could clarify what chipset is used? Update - see his later mail below showing it's Atheros AR5008 based? That's the chipset used in MacBook/Pro 802.11n mini-PCIe cards from Apple.-Mike)
It pops up in the menu bar and says it is a Network Controller card Vendor Unknown. Has anyone had any luck with one of these yet? I am on an original MacBook Pro 15" 2.0 GHZ

(Corey later wrote RAlink sent him updated drivers, but they didn't help. And on Wednesday he sent another mail that the card is AR5008 based??)
Well, I apologize it would appear the information I was given is wrong. It is not Ralink based it is Atheros based. Here is the info from Windows. If anyone has any help for this it is much appreciated.

(Clip from Windows info)
Name [00000016] Atheros AR5008 Wireless Network Adapter
Adapter Type Ethernet 802.3
Product Type Atheros AR5008 Wireless Network Adapter
Installed Yes....

Thanks, Corey"

As mentioned earlier this year on the 802.11n page here, the wireless N cards in the MacBook and MacBook Pro are Atheros AR5008 based.
BTW - Earlier this year a reader tried the PCI drivers with a Belkin N1 PCI card also and they didn't work (different chipset on the N1 PCI card).
If anyone else has found a 802.11N Expresscard that works with the RALink drivers (or natively) let me know.
Previously many core duo MacBook Pro owners just swapped in an apple compatible internal 802.11N card. (Apple Mac Pro kit card, or dell 1500, and later some mac dealers sold similar cards, although priced over what the apple and dell cards sold for.)
Early this year a reader that worked for a company that didn't allow internal wireless cards said he used a natively compatible Expresscard IIRC, but I'll have to dig into the old mails to find that mail with the card model.)
