TP-Link High Power Wireless USB Adapter TL-WN7200ND Review

Tplink Banner
This review is made possible thanks to my friend, Kiang Loon who’s kind enough to lend this to me. Let’s jump right into it shall we.

In the box, you will find the USB Adapter itself, a 5dBi antenna, a USB cable and some documentation.

Actually earlier on my friend wanted a high power wireless USB adapter because his laptop couldn’t connect to a free wi-fi hotspot nearby. So I searched the Low Yat price list and found that this was the most powerful adapter that I could find. Also, it is quite reasonable at only RM59 and that is probably the best power-to-price ratio out of all the wireless USB adapters out there. Let’s look at the spec sheets.

This is a 150Mbps wireless USB adapter but most importantly, it has an output rating of 27dBm which also translates to approximately 500mW. From now on I will use the mW scale for easier comparison. 500mW is the highest you can buy from a computer store, any higher than that you’ll have to buy it online.

500mW is a colossal amount of power. For comparison, a normal wireless USB adapter or even the built-in wireless card in a typical laptop can serve up to 50mW only. That’s an increase of 10 folds in the TP-Link WN7200ND !

That is quite a bold claim made by TP-Link for a product that costs only RM59. I will do some tests comparing it with my trusty Engenius EUB-362 EXT which I bought from Singapore and has around 200mW of power. In the test I will also include a typical Asus wireless USB adapter to act as a baseline in the comparison test.

On the top left is my Engenius EUB-362 EXT, top right is the TP-Link WN7200ND and finally the bottom one is an Asus WL-167g wireless USB adapter. Below is a comparison table for better understanding of the three adapters.

Brand/Model Output Power Wireless Standard Price
TP-Link WN7200ND 500mW N 150Mbps RM59
Engenius EUB-362 EXT 200mW Super G 108Mbps SGD50~RM120
Asus WL-167g 50mW G 54Mbps RM69

Testing Methodology

I have placed these three adapters near the window of my room and I will only turn them on one at a time to avoid any interference. I will be doing two tests, the first being a simple screenshot of the Windows 7 Network Manager and the second test will be a screenshot of inSSIDer, a wi-fi network analyzer. Also please note that I have my home wireless router turned on, so in the following tests you will be seeing it, the name of the network is ‘linksys’.

First Test

Let’s go from the least powerful to the most powerful shall we. So this is what the Asus WL-167g can do.

This is its’ best effort, it can only detect one other network.

Next, is my trusty Engenius EUB-362 EXT.

Besides my linksys, it can detect 4 other network. Good effort from the EUB-362 EXT.

Lastly, here comes the moment of truth for the TP-Link WN7200ND.

It detected two more networks compared to my EUB-362 EXT. I’m starting to feel impressed by this little guy here.

Let’s go into the second test to find out more.

Second Test

Analysis for the Asus WL-167g.

Next up is the Engenius EUB-362 EXT.

And finally, the TP-Link WN7200ND.

It can be seen that on the TP-Link WN7200ND, all of the networks detected had better signal strength compared to the Engenius EUB-362 EXT. None of them falls below the -90 dBm level unlike on the Engenius EUB-362 EXT. Anything at or below -90 dBm is unstable. Judging from the analysis, the TP-Link adapter should provide a stable connection to all of these networks (if I have the password lol).

Conclusion

The TP-Link WN7200ND is definitely a good buy because it has proved itself to be a true high power wireless USB adapter. At RM59, it is simply unbeatable. If you noticed, it is also the cheapestย out of all the adapters that I’ve tested here. I know the prices of typical wireless USB adapters have dropped to around RM20 to RM30 but why not spend a little over RM20 more to get a powerful one? For those of you who are planning to buy a wireless USB adapter, you just have to get this one. You will not be disappointed.

      I just bought the 8200nd and it works well. I want to buy a 2nd one but I’m thinking about the 7200nd instead. Any advice on the difference esp the range? Diff is about S$10. It’s a lot more ex in Sg. 7200nd costs S$35.

    Nice review!

    Can you do a review on the TP-Link TL-WN822N too and then perhaps compare with its brother the WN7200ND?

    • Wai Hung05-03-2012

      Thanks Bob ๐Ÿ™‚

      I’m afraid I’m not able to review the TL-WN822N because I don’t plan to buy the unit.

      But from the spec sheet I can see that it’s less powerful than the WN7200ND, the only thing that it does better than the WN7200ND is its’ transfer speed.

      If you have a homeserver at home where u keep all your files and you want to stream it wirelessly i suggest getting a Wireless N adapter.

      Again, thanks for reading ๐Ÿ™‚
