The GN-621U also reduces "dead spots" within the wireless coverage. The transmission data rate when connecting with wireless 802.11n devices is up to 300Mbps, which makes signal travel farther and maintain wireless connections much reliable than traditional wireless 802.11b/g network.

Not quite 100%

Got ne of these a month or so ago. Running Win7 x64 and have had issues with it dropping connection and having hard time connecting to the router. All other wireless devices work fine. Mine was an ADDON NWU281 using the Realtek Win 7 x64 driver.

May replace this shortly if I can't get it working 100% stable.

Great Value

The device I received wasn't the GN-621U in the description, but an ADDON NWU281 which offers the same spec. This device works great on Linux.

It doesn't get as much signal as my old adapter (WG111v2) but the connection is much stronger. Seems to give a constant 54Mbps rate on a 802.11g network. I am sure this will preform very well on an 802.11n network too!

Great Product

Just rebuilt my computer and wanted it wireless. No need to spend a fortune on the big brand names because this works perfectly. I get exactly the same download speed from this as with a cable. Win 7 64 bit users will have to download the driver from the manufacturer's website in RAR format so make sure you have a program that can extract the driver files. 7zip is a good free download to do this. Top service by OC once again!!

Excellent for Linux

Really brilliant little gizmo - have been using on my
Linux Box for ages now. Fast and reliable and highly
Using Ubuntu 10.10 - for linux users download the
linux script that comes on the CD. Then follow the
instructions to load the driver in "Method 1" - reboot.
Works a treat, one of the best solutions I have found
for Linux.

For those not converted from Windoze yet, then get
hold of a copy of Ubuntu 10.10, and try it for yourselves. It's a live CD, so nothing to install - plus
the bonus of Linux is that it's Free. We like that.

Great product,
No hassles at all, and great connection considering it's plugged into the back of a tower and going through many walls and a floor. Far better than my old belkin dongle that couldnt handle a connection down a hallway. Real value for money, I can't praise it enough!

Good for the money

Its very small and obviously the cheapest, it is wrongly labelled as 300Mbps however as it can only manage 150Mbps on a MIMO wireless N network to my disappointment.

However full solid signal and still 3x faster than wireless G. So not bad.

Craig 2010-05-21

Great USB Wireless Adapter

I bought this after reading the other reviews hoping it would be somewhat better than the awful Belkin one that I had.

This has consistant full signal and I have had 0 problems so far with downloading, gaming, and drop outs.

Definately recommended to anyone looking for a cheap USB Wireless adapter.

Dan 2010-04-15

Cheap and Incredibly Good

After months of trying to find a way of routing an Ethernet cable from downstairs to my bedroom, i gave up, bit the bullet and bought one of these. I wasn't expecting much, but it absolutely blew me away! Five minutes or less to set up, brilliant signal always! I have never looked back on the decision and don't think I ever will.

Fantastic Value

Having spent

Kev S 2010-02-04

Great bit of kit

I got this while buying a built bundle to replace a laptop. If I am honest hand on heart I didnt expect much from this little adapter and it was just going to tie me over until I got time to run some more cable round the house for a proper ethernet connection. I have a Belkin Router and this little beauty works perfectly with it. Speedtest.net show it to be as good as a wired connection with hardly any jitter on the line so its perfect for online games to. So far so good and hey less wires means less clutter so its all good.
