Too many disconnection problems and not only that. I had it for quite a while with the latest 2024 drivers that Windows Update installs, which drivers eventually caused blue screens at random times, because the driver `rtwlanu.sys` would throw an error, that is, the device's driver (just search this driver name on Google and you'll see the lovely blue screens it causes).

The device has Realtek chips, which are notorious for poorly made drivers full of problems. Avoid it at all costs! Even after I installed a more stable driver version from 2020, it didn't save me from problems. What else can I say?

I've had it for a year and a half, and for almost the whole year, I couldn't do anything; it started to freeze and wouldn't connect. It's not worth it; you spend money, and in less than a year, it has broken

It lasted me for a year without any issues. Now it started disconnecting every 5 minutes. I uninstalled and reinstalled the drivers, but it eventually gave up and now I don't have internet anymore

For about 4 months it was good. Now it disconnects every 2-5 minutes. Drivers, other USB ports, testing on other systems... nothing. If you want a serious-stable internet, stay away from USB adapters in general.

I had a turbo-x adapter that frequently disconnected and had poor signal. With mercusys, I saw a huge improvement for the better. I went from 2 bars of signal and constant freezing to 4 bars of signal and rare freezing. I have been using it for about 6 months now on Windows 10. The low price and easy installation are also a plus

Perfect range but as someone else mentioned in the comments, the speed is at 50-60 with a 100 line and especially when something else is connected to wifi, it drops even more...

They may present it as up to 300, but I only reach around 60-70 with 100 grams with this and it also lags in gaming when even 1 mobile is connected to the wifi. In no case would I recommend it for gamers or people who do downloading

From where I had 2-3 lines, now I have 4 solid lines. And when I put something heavy, it charges immediately without any problem. It's worth someone buying it. I am satisfied.

Only the antennas are indeed big and not aesthetic..otherwise it's fine (I reserve judgment as with tp-link it didn't even last a year and it disconnected on its own)

I also had the TP-Link adapters that freeze, disconnect, and are not compatible with all Windows versions. I have changed the antenna and installed one with 18 dB, but nothing. It's in their DNA to freeze and disconnect. I bought this one to try it out and it has better signal strength, stability, and speed on the internet. The quality will be determined over time. IMPORTANT - First, install the installation CD and when it asks you to connect the adapter.......5/01/2022 After 4 months, I can say that it is far superior to TP-Link with much better signal. However, it only connects to 2.4 and achieves similar speed, so with a 100 Mbps 5G, you won't be able to fully utilize the speed of your router
