Mini PCI cards for x30 - IBM or Cisco?

[dc_slim]

Hi all,

I just ordered an x30 Thinkpad from IBM's certified used equipment department. The machine is a 2673-42U. Got a great deal on it -- can't wait for it to arrive.

Here's my question -- the sales rep told me that this is one of the wireless upgradeable models. I've checked the hardware manual, and it looks like there are two Mini PCI cards offered:

1) IBM high rate wireless LAN Mini-PCI adapater with Modem II

2) Cisco Aironet Wireless 802.11b Mini-PCI by IBM

Does anyone know if there's any real difference between these two cards? Any difference in performance, usable range, reliability, etc?

Any information would be much appreciated.
