TP-Link USB WiFi Adapter for PC(TL-WN725N), N150 Wireless Network Adapter for Desktop - Nano Size WiFi Dongle for Windows 11/10/7/8/8.1/XP/ Mac OS 10.9-10.15 Linux Kernel 2.6.18-4.4.3, 2.4GHz Only

This wifi adapter still works 3 years later. Great quality.

This product works well, meaning it integrates successfully with the computer. Highly recommended

Real simple and easy works great no issues :)

I got this USB WiFi adapter for my Beelink Mini PC that recently had WiFi hardware failure, which basically turned my Mini PC to a brick since you really can't do anything these days without internet. I tried to fix the Beelink Mini PC but was no use so decided to give this USB WiFi dongle a try before replacing the Mini PC with another one.I picked this one for price that was under $10 and the next day delivery, and it turned out to be a plug-N-play even though it came with an installation CD, which is no use for me as my Mini PC does not have a CD reader.It's tiny USB dongle that looks identical to my wireless mouse receiver and it worked flawlessly. I don't get the as fast internet WiFi speed on this but it works without any issue so I do recommend it. Hopefully, it will last for more than a year!

Easy to install

Easy to install and really nothing to configure. The wi-fi transceiver on my old laptop broke. So, I got this external wi-fi adapter in order to keep using the laptop. It's an older laptop, so I don't mind that this adapter works only in the 2.4 GHz frequency. It's a very good replacement and works just as fast as the built-in wi-fi adapter that broke.

Well, after about 6 hours, I can confirm that this dongle works on Ubuntu Server 20.04 without the need to install any 3rd party drivers. Why did it take me 6 hours? Well, you can see my list of notes below so you can understand what I went through:1. The dongle doesn't seem to work when using networkd. It appears in the list of adapters, but it refuses to connect to the wifi network. I specifically disabled the Network Manager service and enabled the networkd service and through some other testing, I know for a fact the machine was reading from my yaml file. Wired connection worked fine with my yaml settings, but the wifi adapter just wouldn't connect to my network. So, I ended up using Network Manager. Since this is the server version, I used the nmcli tool, as there is no GUI. I believe you can also use nmtui. Maybe I'm doing something wrong; maybe you'll have better luck.2. The wifi adapter doesn't seem to connect to the network until after the machine is done booting up. This means you'll be sitting on the "Start job is running for wait for network to be configured." line for about 2 minutes until it times out and continues with the rest of the bootup procedures. You can disable this delay by disabling and masking the systemd-networkd-wait-online.service service. To clarify, you don't have to log in for the wifi to connect to your network; it should be connected once the bootup process is done and you're taken to the login prompt.3. Because of the issue mentioned in #2, you might encounter an issue where, even after connected to the wifi network, you are unable to resolve domains and get the error message similar to "Temporary failure resolving". If you encounter this, updating your /etc/resolv.conf file won't work because it resets your nameserver to 127.0.0.53 when you restart the computer. There are a few workarounds, just google something like "resolv.conf resets after reboot" to see what others suggest.As far as performance goes, I was only able to get 40-50mbps. This was with the computer in the same room as the router. Since I'm using this as an in-house GitLab server, it's sufficient. Still, only 1/3 of the advertised speed isn't that great. So, docking 1 star for that.UPDATE: It seems all my issues were caused by the fact that my network broadcasts both 2.4ghz and 5ghz bands on the same SSID, but this dongle only supports 2.4ghz. Seems it was trying to connect to the wrong band and that's where things broke down. If you look at the netplan manual, you can specify a "band" value within the yaml file to set a band you want to use with it. I'm adding 1 star back to this review, since the speed limit is due to multiple devices on the 2.4ghz band and not the dongle itself. Still, advertising 150mbps when you know you're unlikely to get that is pretty misleading.

short version: the RMA process makes you waste hours talking with an incompetent support agent so you'll give up. I bet this review gets the same cut/paste "check your drivers" reply as all the other bad reviews. If we knew when we started trying to get an RMA how many hours we'd waste, I would have just bought one from Plugable and thrown the tp-link one out.long version:The wireless card in my wife's Surface Pro 3 died, so I bought this to replace it because of the 2 year warranty. However after a year and a half, it would only work half the time. No software or driver changes were made, not a single other device in the house has issues, there's been no interference from the neighbors, and our router has always been insanely reliable; this was definitely a hardware issue with the product. She borrowed another wifi dongle so she could get online to chat with a support rep about getting a replacement, but the rep kept wanting to re-do diagnostics that were already done, and couldn't understand that if she unplugged the working borrowed dongle to put back the failing TP-Link one they'd be disconnected (a Surface Pro only has 1 USB port), nor could the rep understand it wasn't a driver issue. She was forced to disconnect and start a new chat later from her phone (obviously much harder to type on). The chat agents kept asking questions that she already had to answer in the form to start a chat, so clearly the support company can't even set up their own software correctly. The support agent was also extremely slow to respond, didn't always use clear English, and frequently transferred her. Eventually they insisted on being sent a picture of the computer, but the chat program didn't actually have an option to send pictures. After being told this, the chat agent took several minutes to respond with a picture pointing to a button that doesn't exist saying "use this to send pictures". After being informed (again) that no such button existed, agent sent the exact same picture. The most insulting part is the agent kept saying "I understand..." when clearly they didn't. Finally we got them to let us list all the troubleshooting steps that proved this product was defective, then they forced us to try various increasingly silly ways to "fix" the issue, all clearly indicating that the agent didn't actually understand networking diagnostic (I am a web programmer who's been building and maintaining my own computers for over a decade, trust me when I say these steps were absolutely unnecessary for proving that the product was defective)The support agent was regularly so slow to respond (more than 5 minutes, sometimes more than 10) that WE got a message saying we'd be disconnected if we didn't reply (while waiting for the agent to answer the last thing we said). Over an hour of slow replies later, the agent starts again asking for photos and things that we already stated we tried and we had to give up and disconnect. No matter how many times we said "we already tried that, as I told you" they just kept asking the same questions. Total time wasted so far was about 4 hours.A few hours later they finally agreed to do an RMA but they refuse to pay shipping on the defective part or let us throw it out, so we have to spend almost as much as it would cost to buy a new one just to send the broken one back. At this point we regret ever trying to get them to honor the warranty because of how much time it wasted, but also figured we might as well finish the process up so we at least get the replacement part for all our hassle. after mailing the defective one, we finally got a replacement a couple weeks later. SO far that's been in use for a little over a month, we'll see how long it lasts.Next time I'll buy from Plugable instead, as they state their support is based in Seattle and from what I've read they don't hassle customers nearly as much about replacement of a defective product. I will never buy a product from TP-Link again, unless perhaps a more skilled support agent sees this review, profusely apologizes, and sends out a more reliable model to compensate us for all the lost time. I'm guessing the reply my review will actually get is the same cut & paste "check your drivers, sometimes interference happens, our support team would love to hear from you" response as the other bad reviews.
