Marginal performance - marketing triumph ... engineering flop 
2008-05-23
After stellar performance of the parent dual-band WRT600T router with my plain jane laptop some 50 feet removed - and the exciting image of the happy family computing all over a multi-story house on the box - I purchased this multi-band wireless receiver to join the cheerful crowd. Not so! Had hoped to 'unwire' my cabled net of 3 desktops for neater appearance; surely not with this underperforming weakling.
Using a big Dell (XP/SP3), the vaunted automatic link with the router failed - even after placing the antenna within 3 feet of the router. Laborious manual installation, though eventually succesful, was a pain; not helped a bit by differing terminology for arcane topics between master unit and slave receiver. The final signal at a desktop less than 30 feet away, separated by a thin plaster wall (no hindrance to laptop reception) was just 2-to-3 wavering bars ("weak"), and switching to the 5 GHz band required tedious reentry of the 16-digit security code.
A dual antenna USB plugin receiver sounds like an ideal solution for interconnecting desktops in a Wi-Fi environment -- but this premature release needs a lot more work before being ready for prime time. And online help is an annoying 'Catch-22', without direct email link to tech support. Shame on Linksys for not matching its outstanding router to this prematurely released underachiever. Better off to get a generic unit at half the price.
Oh, and not so by the way, this unit installs only only a PC. On my MacPro it went totally unrecognized - further negating any chance of one happy computing family. Two stars for 2-out-of-5 reception bars underperformance.
Disappointing performance 2008-05-14
I purchased this client adapter along with the WRT600N dual-band router and the WGA600N dual-band gaming adapter (everything was Linksys dual-band). After setting up the router and gaming adapter with no problems, I attempted to connect a computer to the network using the WUSB600N.
This adapter comes with a USB extension cable with a base at the end, so you can position the adapter in a favorable location. With the best reception, Windows reports the 802.11N connection as 270 Mbps. After connecting to my router, which was almost exactly one floor above, the connection quickly slowed and settled between 12 Mbps and 27 Mbps. This means that the 802.11n performance of this adapter was worse than the performance of the previous 802.11g adapter I was running on the same computer. In addition, I found that I could not transfer any large files across the network (802.11n to LAN, 802.11n to 802.11n, and 802.11n to 802.11g on the other band). The transfer would simply hang, and the connection would stop working. I could only restore the connection by unplugging the adapter and plugging it back in. I eventually found that I could get large files to transfer by plugging the adapter directly into my USB port, but the reception was very poor there.
All in all, I would say that this thing is not worth the money I paid for it. It would probably suffice as a last resort for connecting to an 802.11n network, but it seems to be pretty finicky about the USB power, and I never got a satisfactory connection with it, even though I am using all Linksys hardware.
works...ok...but a bit bulky and similar performance as wirless G

if you think it works faster or better coverage than wireless G, forget about it. it might be faster, but for web surfing and upload, download, it hardly make any different between wireless G and N. Coverage not any better than G, it certainly has problem going through wood walls and gets disrupted by 2.14G cordless phone. dont believe in the hype and spend extra for the N , stick with the G.
No probs operating in dual band. Will buy another.

I had no problems installing on an old Dell 4550 with XP Home Sp3.
It easily connects to either the 2.4 or the 5 Ghz bands being broadcasted from my WRT600N dual band router over 50 ft and 5 walls away. I have the 2.4 band set as my default profile but have no problems when I choose to connect the the 5 ghz band. Consistently getting over 54 Mbs. Very happy. I found it gets much better reception than the Linksys WUSB300N Wireless-N USB Network Adapter.
works fast with Linksys wireless N Gigabyte router

I have XP Pro svpk 2. the adaptor is located in the next room from the router... The router has the WEP2 wireless security function and the adaptor allows for easy auto setup. The adaptor was plugged directly into the back USB 2.0 port instead of the extended wire connector. It installed easily..and for the past hour it has vacillated from 54 Mbps up to 108Mbps... happy-happy. Its connection data shows it is connected at 2.4Ghz.. I have not found how to change it to 5Ghz nor does the wee bit of documentation tell you. I tried the 54 Mbps PCI card and it dropped the wireless connection every few min. The Netgear WPN111 USB adaptor tried its best to connect and has a lovely dash board with easy to understand connection data, but it too seemed to lose its connection to the router, and as with other reviews on the Netgear product it was always very hot. I tried this USB because it matched the Linksys router data. I will try it out for the next few days and report back. I also have found the Linksys technical support to be horrid. My experience with external adaptors for wireless desktops has been dismal and hope I have found the solution by getting the WUSB600N.
Very easy to install & works great. 2008-07-20
This product is easy to install, easy to use, and it works. What more could you ask for?
Great Speed but not bargain price 2008-07-15
I just bought this product. The transfer speed is great and work very well with both of my linksys and netgear wireless router. Top transfer speed was believe to be at the rate of 270 which is very close to the 300 promised by Linksys.
The item is not as affordable as many other N wireless adapter.
Very good performance with occasional quirks 2008-06-24
I bought two of these; one for my MCE 2005 machine and another for my kid's Vista Basic. Installation went smoothly for both machines but it was easier on Vista.
The Media Center 2005 (MCE, basically Windows XP Pro with SP3) experience has been mixed. For the most part the device works well, but it doesn't seem to like using XP's zero config service to run the adapter. My personal preference is to let Windows manage the wireless adapter so I don't have one more useless craplet installed in my Startup folder. Most of the time, (80%) Windows detects the adapter properly on start up and everything is fine. Occasionally, though, it doesn't and I have to manually start the Linksys config utility to force a connect to my network. (I'm using the "matching" dual band Linksys router with WPA2) It's not a huge deal, but it is an annoyance.
Performance-wise, both my systems are reporting 270Mb/s and I can definitely feel the difference between this and my old 11g network. I spend a lot of time in first person shooters and the experience has been the same as when I was physically connected to my gigabit ethernet. The Vista machine is experiencing an interesting problem with stuttering during video streaming (via VideoLAN/VLC) that I wouldn't expect on 11n and that I don't see on my laptop running 11g on the same router. I have not had time to troubleshoot this yet, so I don't know the root cause of the problem.
Some other reviews have noted that the 5 Ghz band signal strength seems to fall off quickly. To some extent this is to be expected; 5 Ghz is going to attenuate (lose strength due to walls and other interference) much more quickly than the 2.4 Ghz of b/g. However, I'm surprised by the signal strength drop between my two PC's. They're only separated by a single wall and perhaps 2 ft. Yet I get 5 bars on my MCE machine (same room as the router) and on the Vista machine I'm only getting 3 (just on the other side of the wall). I cannot prove it but, based on this problem and video stuttering on the Vista machine, I suspect that the Vista drivers may not be fully baked yet.
Tech Support told me to return it and get a different type !!

I bought this adapter for my daughter's desktop PC in the hopes of obtaining a decent range. I had an old wireless "B" PCI adapter from Netgear for years, and signal was always very marginal on this PC.
I also bought a Linksys WRT600N router to upgrade my whole wireless system too. The idea of dual band 2.4/5Ghz seemed attractive enough. Also, I thought that by buying from the same manufacturer I should have very few issues.
I have four PCs at home 3 x wireless "G" (XP SP3 + Vista SP1 + MAC)+ 1 x wireless "B" (XP SP3), so this USB Wireless "N" computer would have been the only one capable of all the extra features and range.
The installation of the USB adapter software went fine and it connected almost right away. So I thought I was done. Almost immediately my daughter started complaining of lost connection issues. I blamed it on her finagling with the wireless software, but it turned out that she was right. The system would take a long time to connect after booting up the PC, then would disconnect after 2 or 3 minutes, and would connect again may be 30 min later. I could not manually force a connection (even though Linksys software advisor would say that I was connected to the router).
To summarize, I called tech support today and was pleasantly surprised to speak to a human after no more than 2 minutes. But after 50 min on the phone, and several holds while he was in turn asking questions to somebody else, he came back saying that I'd be better off returning the USB adapter and getting a Linksys WMP300N which he swore is a dual radio band (even though I read somewhere that it works at 2.4 GHz only).
Too bad I bought this online, but it was from Amazon, so I am returning it today.
works like a charm where G version wouldn't work at all 2008-05-31
I have tried numerous adapters without success.
This wireless n adapter with the matching wireless n router works like a charm.
