Home > Consumer Reviews > Linksys Wireless-N PCI Adapter WMP300N

I'm returning the product tomorrow! Product worked great (!) the first day and I would've given it 5 stars if I posted the comment here that same day. It was fantastic to see 200+Mbps registration and worked as advertised. But subsequently the following days the computer intermittently crashes and you'll be greeted by the BSOD. Yes, as the other reviewer noted....DO scour the internet with the keywords "BSOD WMP300N" and you'll find out this is a recurring problem, unsolved as of this writing. Uploading new drivers at Linksys web sites and going through all the forums for tech advices did not help. It's a shame after all these years as a Linksys fan, I will have to see other competitors out there will be earning my business.

If you run your computer for a few hours you will get the Windows Blue scree of death (A serious hardware error) This is a known issue with this and a few other Linksys adapters. They haven't done a good job here with the driver software. Do search on BSOD and WMP300N to see all the posts.

I'm a major geek. IT people ask me for help when they have problems.

I needed a card on short notice, and bought this one because I "knew" that Linksys made good stuff. Serves me right for not checking things out in advance as I normally do.

I debated installing the drivers manually, but decided to follow the manufacturer's instructions. Big mistake. The Linksys wireless management software conflicted with the XP Zero config utility and neither one would run properly. The Linksys software also spontaneously crashed and rebooted my box.

I uninstalled all the Linksys stuff and manually installed just the drivers. That seemed ok, but no matter what I tried, I couldn't get an IP from the router for the card.

I thought I had some problem with wireless security and encryption and tried all different variations and combinations.

I finally turned off the XP wireless configuration and reinstalled the Linksys utility. After playing around with it a while, I found some built-in diagnostics. I ran them and the program reported back 2 memory related failures in the card.

So it turned out that the card was half dead out of the box, and I wasted all that time thinking I had a configuration problem.

Bad hardware and even the sucky Linksys software agrees.

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.

I purchased this adapter to replace my wireless G USB adapter. My old adapter always had a weak signal and would frequently drop the connection. I decided on the PCI adapter figuring it would provide a stronger signal, little did I know what a pain it would be to install. I'm running Windows XP w/ SP2. I followed the directions and installed the CD first, then shutdown and installed the adapter. The computer recognized a new device, but it continually failed to load the drivers. I spent the better part of three or four days messing with this and used the online support chat through Linksys, but nothing seemed to work. Not sure what finally did the trick, maybe the fact I was ready to pack it up and send it back, but it is now finally working. Have not had any problems since and the speed is much better than with my old USB adapter. The only downside now is that the cable for the antenna is only about 3ft, so I'm not able to place the antenna up high where I would like. So if you have the patience and know-how to mess with your computer settings, this is a good buy. Not as user-friendly as I had hoped though.
