Hello,
Every few days my download speed drops massively. Upload remains constant around 8Mbps but download drops from around 20-30Mbps to around 3.2Mbps (the reading from the last test).
Promised speed is 24 Mb - 37Mb and the service centre panel says it measured 40Mb today.
Restarting my Huawei HG633 router fixes it for another few days, it's instantly better.
So what could be wrong?
Notes - I'm testing via wifi but I get the same results when plugged into one of the ethernet sockets on the router. I've disconnected everything (from wifi and ethernet) and get similarly bad results regardless of what one device I connect just to run the test. I think that must mean there's nothing wrong with the cables, wifi or my equipment since restarting the router fixes the speed (which I'm about to do now).
