Have you ever run
www.speedtest.net from a PC or mobile device?
The speeds you get are dependent upon the device used and whether if it is wired or wireless, and how fast the device can go, as well as the throughput of the router and the band used for wireless; just to name a few. For example, the speeds I get on my wired PC can be as high as 140Mbps (even though I pay for 100Mbps), but my 3 year old iPhone hits the speed limit at around 85Mbps whereas the older 5 or so year old iPad tops out at around 41Mbps -- all from my home network when using a strong 5G signal.
There are so many variables; so what do you expect to learn from asking Alexa?
