I've never seen worse! Horrible purchase.

Highly discourage going further with the purchase!
Despite the fact that it can only operate in the 2.4 GHz band, the older Asus PCE-N10 is still capable of giving out 50 Mbps. I put him to bed early and told him to get some rest; I will give the system unit back, and I will give the store this Tplink craft in exchange.

I have included screenshots showing measurements taken at 5 GHz and 2.4 GHz on a computer, as well as measurements taken at 5 GHz on a smartphone at the same time.

Pros

In spite of this, it turns out that dancing while playing a tambourine is the key to success. But, it is extremely deplorable and unreliable.

Cons

It was unable to connect to 5GHz networks with the default drivers that Windows 10 installed, and it caused a conflict with the Razer mouse and keyboard (the software for those devices just failed to function). It was only after installing a more recent version (2022) of the driver from the website that it stopped causing conflicts and began connecting to networks operating at 5 GHz (but every other time). However, while at the same time: 1. The connection to the network is lost with a monotonously predictable frequency. Only reconnects if the device in question is deactivated and then enabled again using the "Network Connections" menu. 2. Neither the 2.4 GHz nor the 5 GHz frequencies reach speeds greater than 30 Mbps (more often no higher than 20 Mbps). It takes up to 6-7 seconds from the time the button is hit till the actual start of the test (ping assessment), so the claim that it just takes 2-3 milliseconds to complete the ping is a deception. I was no longer interested in figuring out why there was such a significant gap in speed between the rate at which I could download and the rate at which I could upload.
