I just tried the BT BETA as you said above!
I got the same result as you 35mb !! but as you said all the other speed test just give me 20-26mb .
Yes I think we both got the same problem on our Infinity or maybe the same reason too.
Hope the Engineer will sort it out for you on Friday and then you know what's wrong and able to post it for me : )
Can you please update what's your engineer says when he came tomorrow so Carvell can mention it to his Engineer on friday if your is sorted.
to be honest do anti -virus capped the internet speed? I am using Norton security . what you and Carvell used?
so we can see if it the problem
Sorry forgot to mention I got no problem with my upload speed. normally I am gettin around 8-9mb . I am happy with it.
My Norton is up to date too. also as all my test done on wired too . I got the same result as you got on Wireless test too 20mb !!!!!!
