Time Warner Cable RoadRunner 10mb/s slow speeds 600kb/s

Hi everyone,

I got big problem, I have Time Warner Cable RoadRunner High Speed Internet Standard 10mbs service in my house (Riverside Ca.) and getting very poor speeds of 400kb/s to 1mb/s down & 550 kb/s up.

TWC Service and Maintenance Techs are speculating it might be rare electrical problem at house causing dramatic drop off in speeds. Here’s a run down of what they checked:

1) Service Tech from TWC came and checked line signal levels from cable, checked good.

2) Checked modem updated firmware, verified with three different modems including his laptop w built in modem, speeds checked equal with all setups around 650kb/s down & 750 kb/s up same as my PC.

3) Bypassed all splitters making a direct run from drop line coming outside of the house to my router directly. Same nothing…

4) On driveway of my house Service Tech opened a Pedestal were a outside cable comes from nearby amplifier and checked signal levels, levels on his meter showed they were off.

Tech called Maintenance

1) Maintenance opened amplifier verified all signals with his meter, checked good.

2) Maintenance decided to check internet speeds from his laptop using my modem directly from amplifier connection using power from his trucks generator. showed 21.85 mb/s down & 1.4 mb/s up …excellent!

3) On the other end he checked (pedestal on my driveway) checked speeds the same way, (from cable coming from amp). showed a big drop off lowly 1.38mb/s down & 700 kb/s up.

4)Maintenance proceeded to replace faceplate (Connection device) from cable coming from amplifier w new one (claiming device can short out from indirect current running through house cable, which can be caused by faulty electrical wiring in house, i.e. back feeding neutral and such etc... He suggested might need Edison to check line outside and electrician inside.

After replacement of faceplate connecting device, checked speeds again from laptop/modem/generator, show 19.7 mb/s down & 1mb/s up excellent! (proof device shorted out)

5) In pedestal connected back my cable line to the new faceplate connector using another port and rechecked speeds using laptop/modem/generator. showed a drop off from 19 mb/s down to 8.3 mb/s down.

(Maintenance stated connection of my drop cable running from house was causing other ports to drop off speed. Again, claiming a probable bad current or signal caused from faulty wiring, and that if this is the case faceplate connection device in pedestal could short out again and soon.)

6) Maintenance proceeded to check speeds on the other end of the drop cable (coming out of the ground to house) using Laptop/modem/generator. showed another drop from 8.3mb/s down 830 kb/s up (from Pedestal) to 5mb/s down & 879kb/s up.

Maintenance requested drop cable replacement to be done in next 36 hours and left.

7)Service Tech and I proceeded to check speeds in my room (hoping for at least 5mb/s speed like end of drop cable ) Not a chance 400kb/s to 600kb/s down & 539kb/s up.

Cool last check Service Tech connected a straight cable run from pedestal connection (bypassing bad drop cable) straight to my modem in my room *using power from house. showed 600 kb/s down 540kb/s up…bad speeds. It’s looking like an electrical problem.

What’s up with that! Can anybody help or had similar problems with electrical power in house dropping internet cable speeds?

I have electrical experience, Your input might help out diagnosing issue

Whats with your post? … and such are dropped in here and there. Are you sending a code?

As to the speed, be sure you are not running any TORRENT or P2P and that you have your WIFI disabled and you are the only user during any test.

&#8230:? not a code think it's a thread script error

In reply to: …?

No wifi straight modem to pc no bit torrent or other software running.

Maintenance Tech ran laptop w my modem from outside line using his truck generator for power and had speeds of at least 5mb/s from drop line, heck at least it's better than 600kbs.

A few hours ago I connected a straight cable line from outside drop line bypassing splitters to modem and decided to try different outlets from different circuits in home to power modem, but speeds remain 850 mb/s and under.

I think today I'm going take my pc outside and connect modem straight to drop line coming from ground (like tech did)and run romex line to Electrical Panel Bus Bar for power and see what I get. (Thereby bypassing electrical wiring and circuits) I'll keep posted

BTW thanks for responding

Just thinking out loud;

Could it be that the 110v is way off? Power line noise affect DSL but I have not heard of cable having that kind of problem.

If the outside test is no help..remember you are still using the same 110v power line.

Time Warner Cheats Speed Tests
by thecodewerks / December 24, 2009 4:09 PM PST

Either the speed tests by SpeakEasy and are wrong or Time Warner is cheating. I am signed up for a 10Mbps connection but both of those test report speed of up to 30Mbps!!! The biggest problem I have is that I also hover around 600KBps while downloading from my server at GoDaddy. I know it isn't a server issue because I can download files at up to 2MBps at work.

I too have had a Time Warner guy out to my house and he has said the signal is quite strong.

What's going on here?
