I have a Dell Inspiron N5050 Laptop with Windows 7 and Ubuntu 12.04LTS OS's.
I also have just moved to BT Infinity Option 1 broadband which I connect to using wireless.
When I run Windows 7 with IE and carry out a broadband speed check it consistently returns 37Mb download.
However when I run Ubuntu with Firefox I'm lucky if I get 7Mb.
I would be very grateful for any advice to help me overcome this problem as I really don't like Windows.
