Linksys WMP300N 
2008-05-27
I've had this product installed for about 2 weeks now, but had problems most of those 2 weeks. It seems pretty stable now though and it is working pretty good for why I bought it.
Good: The computer it's on is the family PC that is basically used for internet surfing, music downloads, and streaming music. My wireless router and main PC are in the basement, but with the WRT600N, I get a good connection (85% with the door to the basement closed) and from 150-200 Mbps.
Bad (on install): I was forced to use the Linksys software. I tried connecting it without it, but I could not get the drivers correctly installed. Even after some google searches and downloads, the adapter just wouldn't work. I punted and used their software.
Bad (after install): Once installed, I had problems with it locking up. I had to stop the WMP300N service and restart quite a few times. I also had problems with it dropping the connection. These were both solved by enabling/disabling some properties (power save mode, vlan administration, etc.). Those seem to have done the trick and I've been good for the last 3 days.
Overall, I know this is a fairly new product and there some kinks that need to be worked out. But once you get it going, it seems to do it's job. I wouldn't recommend this to anybody who just wants a plug/play adapter because this was far from it.
Works perfectly on Windows Vista 64bit Edition 
2008-05-08
Linksys Wireless N WMP300N is perfect for your desktop when you don't want wire running all over your house.
It took me less than 3 minutes to get this installed and connected to my network. I don't understand why some people are having a hard time installing on Vista. I installed on a 64 bit edition without any problems.
NOTE - VISTA OWNERS: DO NOT INSTALL LINKSYS CD.
-Don't follow the directions on the paper, it's for XP
-Make sure computer is off, and plug the card into your MOBO.
-Connect the Antenna
-Turn on the computer, Vista will automatically install the driver.
-When you do a MS Vista update, you will have the option to update the driver.
-Connect to your wireless router.
Yes, it's that easy.
Pretty close to perfect... 2008-05-07
I've had 2 of these cards over six months and just installed my 3rd hooking my plasma TV to it's own PC now. I run Windows XP sp2 on all my PCs currently. I've never had a single problem with any of these. I upgraded my router from G to N.. then over time have replaced ever of my remote PC cards with these N cards. I take the PC down, install the this card, boot Windows asks for the drivers, I point Windows to the CD. I start the Windows connection wizard, enter my security code.. and I'm up.. fast and stay connected. I have never lost connection on any PC ever. Through put is excellent, play many online games without issue, where it was very 'iffy' at best using a G card.
When reading these other reviews... keep in mind many of these people really have no idea what they are doing. The reason i said this product was near perfect (and not perfect) is that you probably get into trouble following the directions (things people that don't know what they are doing do).. Don't fall into that trap. Install the card, bring up the system. When Windows ask for drivers, insert CD and tell Windows to use the CD. You are done. You have to configure your wireless network of course, but that part you need to know or learn when you setup your router.
BEST COMPATIBILITY FOR WIRELESS-N CARDS/DEVICES 2008-04-05
THIS LINKSYS WMP300N WIRELESS-N PCI ADAPTER IS BEST COMPATIBLE WITH FULL-BARS REGISTRATION SIGNAL RECEPTION WHEN AROUND WIRELESS-N DEVICES. IT CAN ALSO COMMUNICATE WITH WIRELESS-G DEVICES BUT IT CAN'T FULLY GET A FULL-SIGNAL RECEPTION. THE WMP300N IS AN EXCELLENT WIRELESS-N DEVICE FOR HOME & OFFICE WIRELESS NETWORKING! YOU'LL EXPERIENCE SPEEDY WIRELESS CONNECTION-SENSITIVITY THAN THOSE PREVIOUS WIRELESS-G DEVICES. LINKSYS WMP300N IS A GREAT PRODUCT & I HIGHLY RECOMMEND IT.
WMP300N Freezes on Windows XP 
2008-03-29
I am running Windows XP, sp2 and had nothing but problems with this card (Linksys WMP300N). In short, the wireless would connect to my router (also Linksys N) for a short period it did provide internet access, but within 5, sometimes 10 minutes, the computer would freeze up. No movement, mouse, keyboard and applications all froze. I spent a couple weeks working off of a number of forums, tried a number of fixes, including bypassing the Linksys management tool, using the Windows wireless manager, but to no avail. I broke down and went back to Frys and picked up a Belkin N today - works like a charm, no lockup, no freezing and the wireless access is up and running again. My best advice, save yourself the headache and pick up a different card - perhaps the problem is related to Windows XP and if your running Vista you may have better luck than I did. No offense to Linksys, love the router. But the WMP300N leaves much to be desired. Thanks for reading and good luck.
No more whining . . . 2008-07-03
I almost didn't buy this WNA because of all of the whining and complaining I saw in the reviews. Seems a lot of people had difficulties installing it and even more difficulty with technical support. I saw folks advising not to use the provided software - not to follow the manufacturer's instructions etc . . . I had my own challenges with the installation and founf tech support to be very helpful. Turns out, tech support did not end up getting me up and running, but they DID get me far enough down the road that I was able to figure it out myself - They could not have known what my "real" issue was because it was the fact that there was some old software from another WNA that had been previously installed . . . When I cleansed my system of that old software, the Linksys stuff installed immediately and has worked flawlessly since.
My advice? Be sure your system is clean of old software before attempting to install new (competing) software.
Oh, and I followed the linksys instructions without any issues once my system was clean.
Incompatibility with Dell Optiplex GX110 
2008-06-30
I bought this adapter for the kids' computer (an old Dell Optiplex GX110,) after I got the WRT330N Wireless-N Gigabit Gaming Router. The adapter would not work at all, even when NOT installing the Linksys drivers as suggested by other reviewers.
I called Dell for suggestions, but they didn't know of any incompatibility. I called Linksys, and one of the technicians I spoke with suggested something rather smart: to try the card in a different computer to discard if the card was bad or not. So I installed it in a Dell Dimension 9100. The card worked seamlessly (no installation of Linksys drivers). So the card worked fine; I'd say more than fine, just not with the old Dell computer.
I returned the card and instead installed the USB version (Linksys WUSB300N Wireless-N USB Network Adapter). I've had no problems with the new adapter since I plugged it in. My kids want a newer computer, but that's another issue :-).
I am loyal to Linksys. I think they sell good products, and I was happy to be able to get a solution within the same brand.
Beware of the bad driver software 2008-06-28
I purchased this card as a long-time customer of Linksys. I have a WAP 4400N from Linksys with the latest firmware, as the access point. I installed this into a Dell E510 Media Center SP2, with only a video card in the PCI slots. I have a boot drive and ***had*** a brand new 500GB Seagate drive for data.
The installation went smoothly, and the card seemed to work fine using it for Internet access (270 MB!). However, when I started to copy 30-40 4MB image files from another file server on my LAN, it would get about 5-7 of them and then hang. After that, the network showed connected, but there was nobody home. I would have to reboot to get a network connection back. I tried this again, and the second time it hung and completely blew out the hard drive that it was writing to! If I try to use the drive in another PC to recover the data, it just hangs. I have tried recovery software and it is no use.
I replaced the drive (thinking it was an infant mortality - 2 months old) and tried the WMP300N again, same crashing results. I have removed this and have taken it back to the dealer. It truly is a dangerous piece of junk! THe new drive and the PC work great without the card.
The Dell doesn't allow me to set IRQs for the PCI slots, as this is probably a driver conflict. However, this is really bad driver software from Linksys, as I have since placed another vendor's card in the machine and it is rock solid.
Buyer, definitely beware! I had tried to get the drivers from elsewhere as much of the lore indicates, but they fared no better. Avoid this card at ALL COST!
Don't buy, non-standard installer and has hardware conflicts in Vista 2008-06-12
Product says that it is Vista compatible but it was not in my case. I ended up having to return this product. First of all it has a non-standard installer. When finally getting it installed in an unusual way, there are hardware conflicts. Try to fix this then it does not even partially recognize the device. If you check the linksys website the only have the old driver which ships with the product. A complete waste of my time.
Devil in the details... 2008-06-03
I was initially pleased with the ease of setup and the range and speed improvement over my old wireless G network. Then I noticed that the audio/video on my receiving computer (Using the WMP300N PCI DESKTOP CARD) had become choppy and static. After days of rollbacks and uninstalls I traced it to the linksys driver for the WMP300N. To make matters worse, the uninstall for this does not work properly and leaves keys in the registry which prevent the new driver from installing without some geek activities that might be daunting to the average user. Then the new driver after I finally got it installed, was much better but not completely fixed. As a former driver developer I noticed that the new driver solution for the problem was simply to saturate the PCI bus with data! The computer equivalent of talking faster and louder so no one else can get a word in edgewise! If you attempt to run other intensive data applications such as gaming, or video rendering applications, this "solution" will cause your computer to hang. Microsoft would NEVER certify a driver written like this.
Since the value of this router in terms of range and speed, depends on the use of Linksys' own desktop receiver solution, the overall system you set up is severely flawed and I cannot and would not recommend it.
I do not know if the laptop receiver card exhibits the same behavior.
