Is the laptop connected directly to the home hub with an Ethernet cable?
The wholesale speed checker would be correct. What are you trying to download, that is showing a low speed?
It could be the site you are downloading from which is slow?
What download speed is it showing?
Speeds were anything between 1mb and 3mb
Was that 1-3 MB/s?
Downloads on Windows computers are expressed as megaBYTES/S
3MB/s = 24Mbs/S (megabits)/S which is very close to the BT Speedtester results.
Sorry it was 113kbs I’ve just checked
Then that is giving you the wrong result.
The BT Wholesale tester result is the only one that BT will accept, as it tests at the last point before it reaches the core of the Internet.
