Easiest setup you could imagine Cookie's mom April 5, 2008
I haven't had this product long enough to know whether it will last, but I was extremely impressed by the ease of setup--definitely 5 stars!

I bought this to add a new Dell desktop PC to our existing wireless-G network, with a Linksys router. (That HAS lasted well, for the last 2 years.) Let me state that I hated setting up the network originally, because I didn't know what I was doing, and I have had trouble adding friend's laptops onto it when they came to visit. I was anticipating several hours of playing with network names, channel settings, and security codes to get it right. Installing the hardware was a bit of a pain, but that is my fault and Dell's--first, because I turned off the computer and started to take it apart before I read the directions that said to install the software FIRST, and second, because Dell made it easy to open their case, but hard to get the back cover off the one empty PCI slot (which looked like two empty slots from the outside). But once I had the card in, the case closed, the antenna screwed on, and the power back on, the directions said to press the button on the front of the router and click "next" on the computer. I did, and about 60 seconds later, the computer was on the Internet!! I wish everything was this easy!

Disappointing C. Bishop (Davis, CA) September 9, 2007
I've had a lot of experience with Linksys products over the last few years and I have always been incredibly disappointed. This product was no different. It did work beautifully out of the box, which was a perk. I had a functional internet connection within 5-10 minutes of popping open my PC. However, after about 1 month of use, it literally just stopped working (no changes in software or hardware during this time). Tech support seemed oblivious to the problem ... Google "wmp54g stops working" and you get 805 hits (as of today at least) all describing the same problem: it works great, then stops working.

On a more positive note, tech support, at least via live chat, was very helpful and had me run a gamut of tests and configurations, all of which ultimately failed. Honestly, I'll never buy another Linksys product because of this failed product and about half a dozen other negative experiences I have had with the company failing to battle test their hardware and firmware. I've personally had very good luck with all netgear products I have purchased. However, I have not had any experience with the newest Range NEXT routers/adapters and thus can't recommend them.

Fantastic wireless adapter JeanK (Somerset, NJ) June 5, 2008
I bought this adapter to install in my Dell Dimension 4550. It was an extremely easy install (much easier and faster than when I installed my network router!). The directions were clear and easy to follow. The adapter picked up my router right away and once I entered my router key, the PC had a wireless connection. It performs flawlessly.

Woes on Windows, Great for Linux Coleman Stocks "A Woo Gah" (Utah USA) March 22, 2008
Like others have mentioned, this card seems to stop functioning altogether at one point or another - but no one has mentioned anything about Linux (or maybe I missed it). Yes, I had this very card working on a Windows box for about three months, and suddenly the third party software decided to stop working with the unit no matter what I did through tech service and howto's off the internet.

Since it was the kid's computer for games like Freddy Fish (stuff that works easily in Wine) I decided to try the card out on PClinuxOS, since it seemed to be the friendliest OS besides Ubuntu I could find.

First thing I did was try the card on it's default rt drivers that were installed with PClinuxOS. At first it said it couldn't find any networks, then I tried again and it gave me a "ra0" option or something along that line. I tried it and my system froze.

After a reboot, I decided to remove those rt drivers and the already installed version of ndiswrapper, use the 'make' and 'make install' commands for the latest version, installed the driver with ndiswrapper, modprobed it, went through the Wireless GUI, and added ndiswrapper as a module to load on bootup (can't recall the command right now).

It might seem like a lot of work but in the end I haven't had to touch any of the command line since. It even signs on during the boot process and if we ever change our essid or pass phrase or whatever I can just use the Wireless GUI again. Ever since NOT using Linksys third party software, this card has lasted two years and doesn't seem to be stopping any time soon.

Works fine J. Pearson February 3, 2008
I have used this card with with a Linksys wireless router for a few months now, and it works fine. I am a surfer, not a gamer. Mine is a Gateway XP system with the router in the basement. I am getting a second of these cards for another PC.
