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?

downstream power levels suck. have you got an attenuator fitted to your cable wire splitter or SH itself ?

three on the main line into the house, two 10dbs and a 3dbs one.

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!

-3 to +7

Re: new 60mb slower than old 20mb!
 
ok I will give it a go and see what happens. Will it mess up he TiVo or V+ box?

Re: new 60mb slower than old 20mb!
 
nope. unless they have attenuators/equalizers fitted to them ?

removed a 10 db forward path attenuator, power is this now:

but still can't get above 10mb on speedtest!

Re: new 60mb slower than old 20mb!
 
did you reboot the SH ?

Chuck 27-12-2012 22:32

Re: new 60mb slower than old 20mb!
 
I have now but no real change, power levels look better in the down but i sthe SNR too high? Speeds are still rubbish!

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!

copy and paste your Operation Configuration.

192.168.100.1 > Router Status > Operation Configuration

Re: new 60mb slower than old 20mb!
 
Sorry to sound thick but where do I find that?

Thanks for your help it is appreciated!
