Hi,

Please also tell us the name and model number of the Wi-Fi card in your computer. In case it's not a computer, then please tell us the name and model of the whole device.

Here are links to some reviews I've found for the Samsung phone and the Lenovo tablet. Since I am unable to post external links here you need to replace "<dot>" with "."

https://www<dot>notebookcheck<dot>net/Lenovo-Tab-P11-Plus-review-Budget-Android-tablet-with-stylus-input-and-keyboard-cover.576581.0.html

Anyway, to make it short, the people who made these professional reviews achieved 318 Mbps download speed with the Samsung A53 5G and about 343 Mbps with the Lenovo Tab P11 Plus.

Keep in mind that these professional reviewers run their benchmarks in somewhat controlled environments, means they make sure there is as little external influence as possible.

If there are neighboring wireless networks present at your location, then that could negatively affect the performance of your Archer AX50's wireless network and may explain why your speeds end up a little lower than that.

The conclusion is that the Wi-Fi built into the Samsung A53 5G and the Lenovo Tab P11 Plus is quite low-end and therefore unable to utilize the full potential of the Archer AX50.
