I have two laptops that are both the same make model etc. Both run the same Ethernet card with the same driver so on your advice I tried the other laptop not expecting any difference. The results are posted below.
1. Best Effort Test:
Download Speed : 41.42 Mbps
2. Upstream Test:
Upload Speed : 3.81Mbps
Clearly a big difference. Similar results on the second laptop for wireless (when sitting close to the router).
So there is someissue with the first laptop. Not sure where I'll start with that but many thanks for all your help in this.
Perhaps I should add that the BTDesktop help speedcheck remains low on the second laptop at around 23Mb/s.
I would advise that you remove BTDesktop help. It's a piece of junk that is not needed on your computer and can cause problems. Once you have done that recheck your speeds.
