1 out of 5 eggsLow-Grade Product

This review is from: BUFFALO AirStation N300 Dual Band Wireless USB Adapter - WI-U2-300D

Pros: Overall, this is a pretty solid device. It worked perfectly for exactly 4 months and then...well, read the cons.

Cons: Bought this thing exactly 4 months ago, and I guess I should just accept the fact that I need insurance on everything these days. It died today and is no longer recognizable by my computer. No damage or over-heating. Just dead. And there's not a thing I can do about it because it's past the 1-month return. Oh well, you live and learn. Last time I use Newegg - boy have they changed for the worst these past few years. I can't tell you how many DOAs I get from here.

5 out of 5 eggsBuffalo Airstation Wirless USB Adapter stick

This review is from: BUFFALO AirStation N300 Dual Band Wireless USB Adapter - WI-U2-300D

Pros: Nice & easy installation on Windows 8 and Windows 7 using included CD's drivers. Great range compared to some other USB Wireless adapters I own. Running at decent speed, hitting 2.4MBs downloads closer to the router, 800KBs downloads on the other side of our house (approx. 50' away from router).
Offers an extension cable and an attachable clip for mounting.

Cons: Is expensive: I've purchased USB Wireless adapters capable of same performance for around $20.
Is large: much larger than the other USB Wireless adapters I've had for years.
Has no connectivity lights to show connection strength.
Very short extension cable.
Attachable clip needs to be attached by included glue strip.

Other Thoughts: If you're using a netbook, laptop, or any portable device these days I would imagine they have built in wireless capabilities so this type of adapter should not be necessary anymore. If you're using a all-in-one desktop or something of the sort that may be relocated this could be useful, though I would recommend an internal wireless card.
I've had trouble sometimes with Windows 8 connecting to my network when using my IdeaPad's built in Wi-Fi but when plugging in this and other USB wireless adapters it connects with no problem. If this device was smaller it would be perfect for that type of situation.

4 out of 5 eggsGood concept for wireless adapter

This review is from: BUFFALO AirStation N300 Dual Band Wireless USB Adapter - WI-U2-300D

Pros: Easy driver installation. Fast connection to numerous wireless AP's. Dual Band accessibility for those of us that have Wireless AC routers and AP's.

Cons: Dual band does NOT mean that it's faster, as it's still a Wireless N (300) adapter. The clip that comes with it requires you to use a 3M glue strip to mount it (wuh?). It's at least twice as big as the other Wireless N adapters on the market and it's cost is somewhat reflective of that.

Other Thoughts: Overall, I haven't had any major issues with this adapter. I had to realize that, even though it's dual-band, it is not an AC adapter. Wireless N is fast for most things you do on the internet, but home network file sharing will still be handicapped by Wireless N (300) and you won't get the desired speeds that you would want to get out of it with the dual-band nomenclature. IT IS ONLY WIRELESS N. That's the skinny. Dual-band is nice, but not at this price for the speed it gives you.

1 out of 5 eggsBUFFALO AirStation AC433 Dual Band WiFi USB Adapter

This review is from: BUFFALO AirStation N300 Dual Band Wireless USB Adapter - WI-U2-300D

Pros: Hi everyone...

As of today, I have owned & used many Buffalo Products for years now & have generally found their products to be very well made. This is the case with this WiFi Adapter. As a matter of fact, I tested this WiFi Adapter against one of their Dual-Band Routers (the BUFFALO AirStation HighPower N600 Gigabit Dual Band WiFi Router) right now in my home & I love it (the Router, that is). The Router offers the options of Dual Band & Dual OS's, which I like. The Adapter uses Dual Bands, which is a good feature that ALL Adapters should offer.

This adapter comes nicely packaged with a Driver CD, a Manual (IF you can call it that), & a USB Dongle to connect the adapter to your PC. ALL of these features are ones I like & approve of.

It works! Other than this & the features I've listed below, this is about all I like about this Adapter.

+ Small & lightweight. (About the same size as a USB Thumb Drive). Good!
+ Dual Band operation. Great!
+ Comes with a Driver CD. Good feature!
+ Comes with an attachment clip for Laptop. Nice.

Cons: This WiFi Adapter offers Dual Bands like my Router (which I like) but honestly, that's about it. I have to say that I'm EXTREMELY DISAPOINTED in the Transmission Speeds of this Adapter. I have other B, G, & N WiFi Adapters that I've used (& still use) that cost 1/3 the price of this adapter & they have TWICE (IF NOT MORE) the speed (& RANGE) this Adapter offers.

- NO External attachment point for an External Antennae (Directional or otherwise). This is a Bad feature!

Other Thoughts: Unless I'm mistaken, out of ALL my reviews that I've posted, this is the 1st review that I've given only 1 Egg on. It's regrettable as I wanted to like this product. Too bad.
I hate to say it Buffalo, but it's BACK to the drawing board for you on this one! This is one of the products that I'll be using in my SPARES Box in the case something breaks down & I need an EMERGENCY REPLACEMENT. This is DEFINATELY NOT one of those products I'll use for everyday use. Sorry Buffalo... Better luck next time...

Until you can produce one of these that offer a BETTER SPEED advantage & an External Attachment Point for an External (or Directional) Antennae.


Would I purchase this product for myself? Knowing what I know now, NO I wouldn't!

Would I recommend this product to others? I seriously doubt it!

4 out of 5 eggsnifty little USB wi-fi adapter

This review is from: BUFFALO AirStation N300 Dual Band Wireless USB Adapter - WI-U2-300D

Pros: First impressions (before powering up and setting up):
This certainly isn’t the smallest USB wi-fi adapter on the market… and I say that as a positive thing. I’ve had other USB wifi adapters that were downright tiny. I mean TINY… if they weren’t attached to a USB port on whatever computer you were using, you would most certainly lose it. The Buffalo WI-U2-300D is roughly the same size as a regular sized USB thumb drive. Not super tiny, but not super huge at the same time.

Powering up and setting up:
Installation was as easy as the quick-start guide makes it out to be. Run the installer on the driver CD and connect the USB wi-fi adapter and you’re good. This adapter is dual-band and was able to pick up both my 2.4Ghz and 5Ghz networks. Sign in to your wireless network and you’re good to go.

Once connected to my 5Ghz network, I did a quick speed-test of the internet connection and this adapter was utilizing the full speed of my ISP.

On to the file transfer test:
(1GB of mp3’s on a network share, transferred from one workstation to another)

Wired workstation that had the files ---> laptop using Buffalo USB wi-fi adapter
1GB - 1 min 11.5 sec

The speed is decent... it didn't blow the doors off of anything, but it wasn't pokey either.

Cons: Other:
It comes with a USB extension cable and a clip so you can clip the adapter to the top of your laptop screen. Upon further inspection, the “clip” has to be attached to the laptop via a small patch of 3M adhesive and then the extension cable latches into the clip. DEF not doing any of that… I don’t like to “adhere” things to ANY of my computers. (- 1 egg)

Other Thoughts: Packaging and Un-boxing:
Wireless adapter comes in standard cardboard box. The adapter itself is wrapped in bubble-wrap, everything else (USB extension cable, clip, quick-start guide, FCC regulatory compliance sheet, warranty sheet and driver install CD) comes in plastic wrap.

All in all, this is a nifty little USB wi-fi adapter. It’s small, but not freakishly small. It’s dual-band. It’s speeds are solid. It’s setup is pretty painless. It’s affordable. That’s the good… but I’m not sold on the “glue-a-clip” to the back of my laptop screen just to use the extender and have the adapter sit at the top of my laptop. Don’t buy this to upgrade the built-in wifi card in your laptop (upgrades are cheaper and cleaner, unless your laptop is ancient). Buy this to have as a backup for those “oops” moments where things go broken… I can count numerous times where a USB wi-fi adapter has saved myself or a client’s computer.

2 out of 5 eggsWorks best with windows 8

This review is from: BUFFALO AirStation N300 Dual Band Wireless USB Adapter - WI-U2-300D

Pros: I am the first to review this item!

I have owned a two buffallo USB wifi cards over the years (150mbps and a 300mbps) and always found their design to be rather cheap feeling. That is not the case with this adapter which feels sturdy and ready for business (but does not have an indicator light). Unfortunately thats the most I can say in the way of pros...see cons

Cons: Test setup:
Linksys EA6700 802.11AC router
Windows 7: Laptop with SSD and Intel ultimate-N 6300 (SERVER)
Windows 8: Surface with stock 802.11n card

I setup a windows share on the SERVER laptop which was connected to the router at 5GHz. I then connected the Surface to the network and attempted to transfer a 700MB ISO via wireless.

My Surface on 2.4GHz peaked at 8.0MB/s and averaged 7.5MB/s transfer speeds

My Surface on 5GHz peaked at 9.3MB/s and averaged 8.0MB/s transfer speeds

My Surface+buffalo adapter on 2.4GHz peaked at 9.3MB/s and averaged 5MB/s transfer speeds

With such bad results I decided to not use a server connected over wifi, as this may introduce more variables. Instead I took the same ISO and put it on a flash drive and connected it directly to the router. Unfortunately I got exactly the same performance numbers.

Other Thoughts: At this point you should ask "hey, why are you not testing this buffalo wifi device on the 5GHz band? They make a big fuss over this device being DUAL BAND". The answer is that this Buffalo USB wifi adapter did not see the 5GHz network when attached to a PC which could see the 5GHz network. I then checked the driver in device manager and it showed that the correct driver was installed. Being a very thorough person I went to the buffalo website to search for official drivers....but alas there are none!

On the subject of drivers. My surface runs windows 8, and this USB buffallo card was detected and installed right away. However windows 7 was unable to find the correct drivers, even when you ask it to search the internet. When you compound this lack of drivers in windows 7 with lack of drivers on the Buffalo website you may find yourself in a sticky situation where your "plug and play" wifi card refuses to play nice.

Overall I am underwhelmed with this wifi card. I stopped buying buffalo cards for just this reason and sadly, 2 years later, they still do not know how to produce reliable products. Additionally the benchmarks I recorded have an average 70mbps....a far cry from the advertised 300mbps.

In my opinion if you are going to have a USB wifi card why would you purchase a 300mbps n card when you can pick up a 802.11AC USB wifi card that is backwards compatible with n/g/b/a?

So should you buy this item? only if you have the following in mind:
Windows 8 desktop which needs to be connected to a 2.4GHz wireless network
