Temporary loss of internet after speed test!

I am experiencing a peculiar issue with my router after conducting one or two consecutive speed tests with Ookla, leading to a temporary loss of internet connectivity for approximately two minutes with "This site can't be reached." error on pages.

The network setup involves 5 devices connected through Ethernet cabling, while mobile devices are connected via Wi-Fi. Interestingly, performing the same speed tests on my mobile phone does not cause any issues.

The router is the Huawei H122-373 (CPE Pro 2) with an EE SIM card and a strong 4G+5G signal. The APN settings are configured for IPv4, with assigned Cloudflare DNS servers. On the surface, everything seems to be in order. I have also performed a connectivity check on all cables and found no faulty ones within the home network.

I hope someone can assist me in identifying the root cause of the issue.

Is the internet not accessible on all devices after running consecutive speed tests?

One of my computers has a cheapo USB WiFi adapter that can get overwhelmed at high speeds and would need a minute or so to reset however the internet connection is still present for other devices when this happens.

Does the same happen if all clients are disconnected except for a single client?

Yes, the internet is not accessible on all devices. I don't think this is related to the PC as I ran the test on my new laptop and the same issue happened.
