Got a slightly strange email from BT
"It doesn't look like you're getting the best from your wireless connection, so we'd like to help you make it better. "
Which was odd, as I've not really noticed any difference between those bits which are Wi-Fi connected and those which are cable.
So I used the BT test.
Laptop - which is my newest computer and Wi-Fi gave:-
34.5 Mbps download
7.9 upload
Desktop PC (cabled) gave:-
16.1 download
7.9 upload.
In both cases speed from exchange to BT hub, 39.8 Mbps. I have fibre to the end of the road, and overhead copper to the house.
So just what are they on about?
