Having moved into rental accomodation recently, I needed to purchase a broadband service. I chose Hyperoptic, which was in the building and a good deal. 150 Mbps down and symmetrical so 150 Mbps up.

One of the first things you do is of course https://hyperoptic.speedtest.net which showed a great download speed but only a paltry 0.7 Mbps upload speed. Tickets were duly raised with Hyperoptic.

As is transpires, however, the problem is not the WiFi service, it is my laptop. All other devices work fine. The issue is with the Lenovo T14s Gen 2 which I have been using since mid 2022. In general its been ok, but it often blue screens with DRIVER_POWER_STATE_FAILURE. Quite annoying.

Now it transpires that the Intel WiFi 6 AX201 hardware has known issues. Just Google for slow upload Intel AX201 to see the longrunning fail from Intel. I’ve tried every setting I can think of and all the suggestions on the web but to no avail. Basically at this point Lenovo is in the dog house and they shouldn’t expect any more orders from me!
