Network Question

[king1]

you could find a speedtest app for your phone and test that DL speed on the cell network, it will be a reasonable approximation of what you can get.
Google might show you a speedtest option as well if you google speed test, just make sure you disable wifi on the phone... Checking ip address confirms which network you are connected too...

Although it seems to be a suggested thing online to disable dhcp to create an access point, I have never had much luck doing that - for me it has always been rather unreliable or just never actually worked...

These days I would suggest a mesh wifi network as the most reliable way to get a good wifi spread through the house. TP Link seem to do some good ones
