4 out of 5 eggsGood Power

Pros: Good Wi-Fi card for the budget, will prefer one with more transmit power, but these one has a detachable antenna, so you can buy a high gain antenna to increase the range.

Cons: Mid range transmit power.

Other Thoughts: Can be upgraded.

5 out of 5 eggsGreat Card

Pros: Installed easily and with no problems. Worked better than my previous card and has longer range. My router is located in the living room, which is about 20-25ft away with about 5 walls in between. And this thing still gets me VERY GOOD signal as opposed to Low or No signal from my last one.

Cons: None.

Other Thoughts: Bumblebee Tuna

2 out of 5 eggsInconsistent

Pros: Price.
Upgradeable antenna which pretty much any pci wireless adapter has.

Cons: Just can't get a good signal despite only going thru two interior walls (less than 50ft to AP). Signal speed fluctuates constantly. This is even with a hawking 15dbi directional antenna. Can't recommend based on my exprience.

Other Thoughts: I know it's not my router because I can use a usb wireless adapter (zew2500) and run it with the buffalo software and get a rock steady 54mbps connection. My only other thought is that I'm getting interference inside of my fairly compact computer case but with the remote antenna I just don't see how that's the case. I bought it based on positive reviews and I was hoping to connect to my router at 125mbps but no such luck.

5 out of 5 eggsWorks great under Ubuntu 7.10

Pros: Installed in Shuttle SFF case running Ubuntu 7.10. OS detected the chipset, automagically grabbed the correct driver and it was up in 2 minutes. Connected to my Linksys WRT54G immediately using WPA/TKIP. Averages 70% signal across the house with 6 other neighboring signals. Absolutely no issues or hassle.

Cons: No real gripes. It does what it was made for and the chipset was auto detected and installed great under Ubuntu, couldn't ask for more.

Other Thoughts: Need to get the Buffalo router and test "125mb" speeds.

2 out of 5 eggsDefective

Pros: When it worked, it worked. Kind of.

Cons: I've had trouble with this card since I bought it a few months ago. The connection was volitile in both Windows XP and Vista. Only by installing Ubuntu was I able to get a consistent experience. I ran the correct drivers in all OSs. It would connect at the full speed and slowly peter out until it disconnected. I'd have to restart the computer to get it to detect wireless networks. Finally, tonight, after running at full speed in XP, it died. I tried reconnecting it. Nothing.

Other Thoughts: I'm contacting the manufacturer about it and I hope that experience will be better than the one with their hardware.

5 out of 5 eggsWorks Great!

Pros: Fast install, under 10 minutes with the provided drivers on the CD. (installed with Windows XP SP2) Antenna is adjustable in the back to get maximum signal strength

Cons: None

Other Thoughts: Great wireless adapter if you need to connect a box to a wireless network. Don't use the Buffalo Wireless Client, use Windows to manage the wireless connection.

2 out of 5 eggsNot Reliable

Pros: The card is fairly priced, but you get what you pay for. Upgradeable antenna is a plus. Good strong signal, when the card is working. Twice as bright, half as long...I suppose.

Cons: This card won't work in a shared hardware IRQ situation. I had to remove a firewire card because of BSOD's resulting from IRQ conflicts. Other wifi cards worked fine in the same PCI slot. Over 9 months this card became steadily less reliable. It dropped connections and required rebooting to connect again. This week the card completely failed, and won't hold a connection at all. The included client software is horrible. It is bloated and invasive. It won't uninstall all of its components. When I removed as much of the Buffalo software as possible I reclaimed approx 50 Mb of RAM from its services.

Other Thoughts: This card was a pain from the moment I started using it. It was very picky about which drivers would work, and conflicted with other hardware more than a SB Live! The frequent connection problems were very frustrating and persisted through many reconfigurations of hardware and OS. I was about to give up on the whole PC when the card finally died. Upon replacement I discovered that this card was the source of the problems. I also had many other problems with a Buffalo router until I reflashed it with DD-WRT. Buffalo is not a dependable brand, and their software development and support are both awful.

5 out of 5 eggsVista install effortless

Pros: Installs automatically in Vista as a broadcom wireless adaptor. After that simply update your driver to the Vista version now available on Buffalotech website. No thrills. Is as advertised.

Cons: Reception could be better. My htpc is in a rack with open front, but bricks around other 3 sides. Wireless router is only 20 feet away, and I get Fair-Good reception (half way).

Other Thoughts: I'm happy with it. And I hope to test the faster connection speed (125) once I update my wireless router.
