Here is how to make it to work:
Install the driver utility before inserting the USB adapter. Running the CD that came with it first is a good way of doing it. Downloading the latest driver utility from TrendNet web site and running it first is another. Actually this is the best way while you are waiting the adapter to arrive, so all you have to do later is to plug it in. The third way is to let Windows 7 to install it for you automatically (if you are running Windows 7, 32-bit or 64-bit) by directly inserting the adapter, but updating the driver might be a hassle. Seemed to me you have to unplug it and then update the utility. If you inserted the USB adapter first and couldn't get connection (maybe that's why some of the reviews here are bad), don't worry. Unplug the adapter and start over. Don't leave the adapter attached when you try to install/uninstall the utility.

Some reviewers said it would always display 150 mbps regardless of the true connecting speed. I was also curious about this and spent some time to investigate. It turns out this is not true. The adapter max out at 150 mbps when it is running at normal connecting speed (i.e., the communication speed between this adapter and the router). This is an indication that you have a good router signal strength. However, when the signal strength or quality is poor, it WILL show lower speed. I have seen 120 mbps and even 60 mbps at different locations or after running the computer for a long time, in which case I would change my location or just put the computer to rest a bit. Also, 150 mbps is not the speed into the Internet. The maximum speed between the Internet and your modem is determined by your ISP (DSL or cable company), and it varies depending upon the broadband Internet package that you pay for. In actual Internet speed tests it can reach 10-15 mbps anywhere in my two story house except where there is a metal blockage. My wired gigabit connection is getting 24-25 mbps. I have set my router to N only mode since I also bought a TrendNet media bridge (which works great) to help other slower g devices with wire connection option.

SIZE: It is pretty small, although not the smallest on the market (refer to this review later). The size matters a lot to me. When you have to carry it around, especially when placed on a bed, you would always wish it was smaller.

1) I wish it could reach 300 mbps maximum connection speed specs as as claimed. The reality is this is a false or misleading claim.
2) The main problem I had was that if I wake up my HP notebook running Windows 7 64-bit, the web connection is mostly likely lost. I would have to re-connect it manually and this is annoying. I have less problem with PLANEX GW-USNano-G.
3) I wish it were a half smaller.
4) The blue LED light was bright and quite annoying. The PLANEX GW-USNano-G has a yellow light and tiny. AirLink has a smaller blue light. Neither one of them are as bad as this one.
5) I paid $26 for this, and now is only $19.

Competitor #1: PLANEX GW-USNano-G Wireless-N 150Mbps USB adapter. GOOD: Price: $17 (vs Trendnet $26), Size 22.5(L)x14.5(W)x7(H)mm (vs Trendnet 34x17x7mm), Speed: 150 mbps (vs Trendnet 150mbps), Band, 2.4GHz (vs Trendnet 2.4GHz). BAD: Max power consumption: ~1.5A (vs Trendnet 0.29/0.32A) This means it gets hot. Range: NA (vs Trendnet 50m/100m), smaller size=smaller antenna=shorter range.

Hands on test: The test was done on an HP Entertainment Notebook running Windows 7 64-bit. When plugged in, PLANEX looks roughly half the size as TrendNet. Signal strength: 5 bars (the same as the TrendNet). Connection speed to the router: 150 mbps. Actual Internet speed: roughly 10 - 15 mbps and very consistent (the same as the TrendNet). Power consumption: I didn't feel any temperature change during the test that lasted half an hour.

Competitor #2: AirLink101 AWLL5088 Wireless N 150 Ultra Mini USB Adapter. GOOD: Price: $13 (vs Trendnet $26), Size 14(L)x34(W)x6(H)mm (vs Trendnet 34x17x7mm). It stick out of the side of the computer for only 0.55 inch! which is only half of Trendnet's 1.3 inch. Speed: 150 mbps, Band: 2.4 GHz. BAD: power consumption: NA (but I read the reviews it gets hot, so I think it draws more amps than Trendnet), Range: NA (smaller size=smaller antenna=shorter range).

Hands on test: The test was done on an ACER Netbook running Windows XP 32-bit, SP3. When plugged in, it looks roughly 1/4 the size as TrendNet. Connection speed to the router: 120 mbps. Signal strength: 4 bars (vs TrendNet:5 bars). Actual Internet speed: anywhere from 8 to 24 mbps (from different locations). The little size means the antenna is small and very sensitive to the signal strength. If you have a large house or a weak router, you may experience slower connection speed with it. Power consumption: I didn't feel any temperature change during the test that lasted half an hour.

I would recommend a PLANEX GW-USNano-G adapter. Reason: Same connection speed, same performance, half the size, half the price.

The good:
Received the product quickly and plugged it in and was up and running at N speed in ~10 seconds, not too shabby. Speed was far and above what I ever got with G, and it works all over my house.

The less than good:
Despite the 300mps claim, I'm pretty sure that the theoretical max of this card is locked at 150mps, and unlike every other wireless card I've ever used, the reported speed does not lower automatically based on real time performance statistics, it always says "150mps".

Why oh why do companies insist on putting OUTRAGOUSLY bright blue lights on things? I had to put a piece of electrical tape over the blue light because it was lighting my bedroom...

It also gets pretty darned hot - which so long as it keeps running doesn't bother me, but experience has shown me that devices that run really hot don't tend to last.

Overall a good product, but I can't give it 5 stars.

I have a Linksys EA6500 Dual Band AC wireless router. I wanted to increase the connection speed over the built-in DELL wireless minicard in a DELL 1400 Vostro running XP SP3. The built-in mini-card maxed out at 54Mbs transfer rate. The TEW-649UB is advertised up to 300Mbs. Lots of things can affect a wireless connection, but I had two cards (one built in) and the TRENDnet. I used them in the exact same locations in identical conditions and got terrible results from the TRENDnet. The wireless router is in a downstairs home office. I use my laptops upstairs in two different rooms. One room is directly above the router and the other is diagonal across the house. In both rooms, the built-in wireless card gets "excellent" (5 bars) signal strength and transfer rates of a constant 54Mbs. In both upstairs rooms, using the TRENDnet adapter, I never got above an "average" to "low" signal strength and a transfer rate BELOW 54Mps. Most of the time I got between 17 to 32Mps. That's about half of what I get from the old built-in Dell mini-card that I wanted to replace. The only time I could get "excellent" (95%) signal strength and a transfer rate of 300Mps, was by walking downstairs with the laptop and sitting in a chair about three feet from the Lynksys router. I got a signal strength of 45% and transfer rate of 73-80Mbs about half way down the stairs. I have three other laptops and all of them get excellent signal strength and over 130Mbs transfer rates to/from my router when used in the upstairs rooms. The TRENDnet's performance was so poor, it is getting returned.

I recently acquired use of my resort's free hotspot for my computers so I've really had to work hard on finding good adapters. Of the several I bought, this one was the least efficient, bringing in about 6-10Mbps on average. And this is a faster N type adapter. My other Zonets, Alphas and Netgears (N's and G's) bring in from 50Mbps to 130Mbps with lightning fast response and hold the signal perfectly. (I'm about 60 feet away from the signal antenna). The necessary driver install made no difference in Windows and my 4 Linux OS already have the right drivers pre-installed. So I can't figure a reason for the poor performance I get with this one. The luck of the draw, I guess.

I have puchased [10-12] of these over the last two years and was truly happy with them until I recently bought the TRENDnet Wireless AC600 Dual Band USB 2.0 Adapter, TEW-804UB. This one (TEW-649UB) performs well but there is NO COMPARISON to the newer model (TEW-804UB)! It's worth the extra money to upgrade to the newer model, the range is probably double and the signal strength for me has been 4-6 times stronger in XP Pro & 2-3 times stronger in Vista Business! The seller ships super fast & I will buy this product again from this seller... Good Luck! RH

We purchased the Trendnet TEW-649UB for my wife's Dell mini desktop system that we have set up far away from the router and have been very impressed with its performance. Dell wanted an additional $50 for a built in wireless card for her desktop system, so upon researching our options opted to forgo the built-in wireless and go for a reasonably priced USB wireless device. The device is VERY small and is VERY stable on her Windows 7 desktop. In fact, I believe we've had less issues retaining connectivity on this device than all the other wireless devices connected to our network. It works great and is tiny to boot, very satisfied with this purchase.

+ Great price
+ 802.11n connectivity
+ Tiny size
+ Very stable

- None that I can think of

I was very happy with the quick delivery but I have come to expect nothing less from Amazon. I plugged the unit into my Win 7 PC and immediately it located the drivers and installed it. There was no need to even insert the driver cd provided with the adapter!

I also tried it on a Win XP PC and there were no installation problems there either. Didn't need the driver CD since Windows was able to locate them online.

My only concern is that the unit runs a little hot. A lot hot actually! I am concerned that this may mean that it won't last too long but I'm pretty happy with the performance so far for the price. Let's see how much mileage it gives though.
