If all you need is 802.11b ( 11Mb ) , then I would definitely look for
one of the older (classic) orinoco/avaya/dell1150/proxim cards. They
have an external antenna connector as well as an internal 2.2 dBi
antenna. And they are VERY well supported under linux. You can also
get them in a mini-pci form factor.
If you want 802.11g or 802.11a, then I am not sure what is
supported.... I simply use 802.11b because internet connections are
rarely more than 1.5Mb. 802.11g is just overkill for internet speed
applications.
While I agree these are good cards, you may want to stop bragging about
a "2.2 dBi" antenna. 2.2 dB of gain over an isotropic antenna isn't
very good in the world of RF.
It's just barely > 0 dBd which is a much better number to use for
comparison when measuring antennae performance.
In other words, if you open up the card and look at it, it's probably a
half-wave dipole printed on the circuit board. The cheapest and lowest
gain practical antenna that can be built that doesn't require a
ground-plane.
I agree about the cards -- they're great. But do the math before
bragging about that 2.2 dBi number... it's wimpy.
