I was talking to my brother-in-law earlier today who is on BT Infinity. His speeds are all over the place sometimes down to around 50kbps then next day it will be up to his normal ~30Mbps again. Uploads are similarly variable. BT won't budge from "It's an internal problem".
So far he has switched off WiFi (on his laptop) and connected via ethernet but I was thinking that the best way to establish whether it's a router problem would be to by pass it and connect directly to the modem and then create a new PPoE connection on the laptop.
Are there any reasons why this won't work or that it's a bad idea? If not are there any special settings or is it just a straightforward new connection?
