I have no idea sorry, it's my parents Internet (well mine too ) and I haven't really taken much notice as to what it is, although I imagine it will be something like 10MB so your probably correct.
And yes there is a problem with my internet i am supposed to be on 8000/512 kbps but for some reason my router modem settings are reporting half that showing the same as the speed test result.
A month or 2 ago we finally got our internet fixed (after years of problems) and We are getting double the internet speed now since we upgraded a few months ago.
