The Buffalo AirStation N450 USB adapter (aka WLI-UC-G450) is a 2.4 GHz 11n wireless adapter capable of a theoretical 450 Mb/s using a 3×3 antenna array. Sweet.
If you are used to small wireless adaptors and tiny memory sticks, then the N450 will be a bit of surprise. It’s a pretty chunky number at a little under 9.5 cm long, including the USB jack. The otherwise plain, but shiny, exterior has a single blue LED to advertise activity.
Setting up the N450 was a doddle. Insert CD, follow the prompts, reboot, insert N450, job done. On my laptop, the adaptor appeared as Wireless Network Connection 2. In order to use the N450, I found that it was necessary to disable the internal wireless card otherwise it seemed to take priority over the N450. (On my laptop there’s a switch for that, otherwise right-click on the icon and choose Disable.)
Initially, the laptop couldn’t see my 11n wireless network, but it could see a different 11g network. I’d had this problem before so I knew what was up. The 11n network uses channel 13 as the frequencies there are clear from interference in my neighbourhood, whereas I have the 11g network down on channel 1. Unfortunately, some Wi-fi devices only recognise channels 1-11 as these are the channels allowed in the US, and it appears that the N450 is one of them.
Once I’d pushed my 11n network down into channel 11, everything went swimmingly. Regrettably I wasn’t able to test out the full 450 Mb/s connection as my access point only supported 300 Mb/s, but it was pretty quick regardless. Even then you never get the full 300 Mb/s but I regularly saw data transfer figures around 80 Mb/s, which I think is about right. Your mileage may vary, of course, and you’d probably get over 100 Mb/s data transfers connecting at 450 Mb/s.
The high data transfer rates will make the N450 of interest to those wanting to stream HD movies over a LAN to a laptop for viewing, but the adaptor needs to be paired with a suitably fast router or access point to get the maximum speed.
Available on-line for around £30. Thanks to Buffalo for the loan of the adaptor.
