My new Dell Latitude 610 has a built in "Dell Wireless 1470 Dual Band WLAN Mini-PCI Card".
I have a Linksys Wireless G card from when I used it with my old laptop - so I thought I would configure is as a backup in case the internal starting acting up.
When I plugged in the Linksys card, the Dell laptop thought it was a "Dell TrueMobile 1300 WLAN Mini-PCI Card". It worked fine. I then changed the driver so that the Linksys card used the Linksys drivers.......the built in "Dell Wireless 1470 Dual Band WLAN Mini-PCI Card" stopped working, and the Linksys Wireless-G using the Linksys drivers also stopped working.
Rolling back the driver for the Linksys Wireless-G card, so that the system thinks it is a "Dell TrueMobile 1300 WLAN Mini-PCI Card" fixed everything so both the internal Dell card and the external Linksys using the Dell drivers all was working again.
Anyone seen this?
