new 60mb slower than old 20mb!
I recently moved to 60mb from 20mb when I got a TiVo box. I know my TiVo box is plugged into my router but I am not getting even the speed I did with 20mb. Any ideas? Is it my power levels?

Re: new 60mb slower than old 20mb!
downstream power levels suck. have you got an attenuator fitted to your cable wire splitter or SH itself ?

Re: new 60mb slower than old 20mb!
remove one of the 10dB forward path attenuators.

Re: new 60mb slower than old 20mb!
What should the power levels be? Any ideas why the levels have gone rubbish since I had TiVo installed?
I asked the engineer to check the levels as we have had problems in the past and he said they were ok!

Re: new 60mb slower than old 20mb!
www.speedtester.bt.com
SNRs good. you are testing via wired ethernet right?
set up a ping monitor, it may be network utilization, high usage.
you could try this > www.speedguide.net/files/TCPOptimizer.exe < move the marker up top all the way too 100+ then above apply changes at the bottom click on optimal then tick the modify all network adapters box then apply changes > restart > open IE and test speedtest.net

Re: new 60mb slower than old 20mb!
I am using a wired connection as this will be more reliable.
It is better after the attenuator removal, getting aroun 30mbps now, but that is half what it should be. Maybe I need someone to come out, I had to before because the signals were all over the shop!
