I moved my system into my new office, which is closer to my cable drop thsn the old. My Charter cable TV works fine in the new office but the internet, on the same cable, does not. "Tech support" yesterday "troubleshot" it and said everything is OK theres a problem in my area. I didn't think she knew what she was talking about, so I moved the system back in the old office and here I am on the internet. Seeems like it has to be a cable problem.... My "on-line" and "activity" lights do not come on in new location. Motorola surfboard modem. |

Isn't there some kind ofs pliter in your cable box outside that feeds directly to your internet cableline? may want to go and trace your wire to from the old office to outside cable box and see if there is a filter/ spliter there. and if there is change the filter/ spliter over to the new office cable line. but i am not sure about this. But i do remember a filter/ splitter for my internet outside. |
What he said. A TV can work with a really shitty signal. A cable modem needs as good a line as you can get it. I've always taken the incoming line from the cable company and had a two way splitter as the first thing in the line. One leg goes to the modem, one leg goes to the amp and the splitters for the rest of the house. |

Take out all the spitters on the new line and run it direct. You have too many splitters and your upstream RF can't reach the CMTS. We split the signal at the home, one side runs the tv's and the other side goes directly to the cable modem. Or they may be using upstream filters which block the upstream from reaching the CMTS, if that's the case, you need to remove the filter. |

Charter uses a lot of junk RG-59 cable so that could be the problem. I've fixed quite a few Charter problems by replacing their crap cable with good quality Belden RG-6. Stripping the coax correctly also makes a big difference. If you look at where most of the Charter employees strip the inner dielectric you'll see that they strip it too far back. That creates an impedance mismatch that degrades the signal. Of course that's not as big a deal as the insulation flaking off of the low quality cable after UV exposure. A month ago in my great-nephew's townhouse I increased the signal at his cable modem by a factor of 22 by replacing about 50' of Charter's RG-59 that had insulation flaking off of it with RG-6 and replacing the connector at their amplifier. His cable modem went from working a few hours a day to working 100%. If Charter actually cared they could have done the same. Of course if they cared, they'd spend about $0.02 extra per foot for RG-6 versus RG-59 and would buy cable that could survive UV exposure.z |
