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 ?

Re: new 60mb slower than old 20mb!
 

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

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!
 

-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 ?

Re: new 60mb slower than old 20mb!
 

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 ?

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!

Re: new 60mb slower than old 20mb!

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!

Re: new 60mb slower than old 20mb!
 

put this in your web browser

192.168.100.1

now top right click on Router Status

then Operation Configuration

copy and paste

Re: new 60mb slower than old 20mb!
 

well your set for 60meg down and 3meg up.

Re: new 60mb slower than old 20mb!
 

Oddly that is what I am getting now, latest speed test shows just over 60mb, really odd.

Could it have taken a while for the power change to take effect?

I don't think I could have been throttled because I haven't downloaded anything unless TiVo box did it!

Re: new 60mb slower than old 20mb!
 

dont know. it should of settled right after the reboot.

Re: new 60mb slower than old 20mb!
 

bizzare, last test went through at 68mb!!! Mental, well maybe it will settle somewhere near 60mb, will just have to keep an eye onit, but it is miles better than it was so thanks for your help it was really useful, at least the power levels are better.

Re: new 60mb slower than old 20mb!
 

TH had it right.

-12 dBmv is too low for the modem to receive data reliably. Once that was fixed, you were going to get whatever capacity is available in your network segment.

Re: new 60mb slower than old 20mb!
 

if the speedtest is jumping all over the place do the TCP optimizer and then test in Internet Explorer

Re: new 60mb slower than old 20mb!
 

BTW, the best speed test to use is Jack Dinn's JDAST. It is multi-threaded and runs from your PC not over the web via a ropey Java app.

Flash Seph ;)

Re: new 60mb slower than old 20mb!
 

I also posted on the virgin forum and got this answer:

After having a look at the part of the network you are connected to there is an issue with utilisation. This has been raised to the Outage team and we have a fault reference for the issue of F002291908.

So it looks like it is a utilisation issue but I am sure my power levels have helped improve so thanks.
