i had the misfortune of thinking this was an awesome deal and bought the usb and pci adapter and the router.
big mistake.
the router is quite possibly the worst router ever. the wireless portion must have a range of 10 feet. and even then the signal starts to weaken (i am not kidding, i was using this from 10 feet away and getting only 3 / 5 signal bars in windows).
worst router ever. i bought a linksys wrt54g for 3 times the price, and beleive me it really is 3 times hell 8 times better.
now on to the cards...
the pci card is almost useable. it only kicks you off the wireless network randomly every i dont know... 4 hours or so. sometimes this requires a restart for some quirky reason. i thought it was my router, but it continued to do this even when i got the universally thought of best router on earth wrt54g v3. anyhow, i then tried using a dlink 802.11b wireless bridge (it was on my xbox) and it was the most perfect thing ever.
the pci card somehow also would cause my router to go insane and force me to reset sometimes. perhaps it sends malformed packets i have no idea. it is a TI chipset card, so perhaps with an alternate driver or utility it could be useable.
now the usb card.
this thing was far worse than the pci one. it could barely make a connection to the linksys router 10 feet away. i just pulled it out and gave up.
so the lesson is this. Airlink stuff sucks. Even if it were free, it would not be worth the hassle of wasting your time getting it to work on your network.
