I've just purchased a Dell TrueMobile 1150, and it works okay, but I was thinking I should upgrade the firmware and upgrade the drivers.
I tried to do both of these from the proxim webpage however when I try to switch the drivers it doesn't see the drivers as a new driver, and if i try to install it manually, there isn't a manufacturer of Dell.
With the firmware upgrade, I get an error that says it's not an orinoco card.
Netstumbler does detect it as an Orinoco card, so I don't think they changed the chipset.
