How to fix a Comcast Remote?

Does anyone know how to fix Comcast's internet when they wont help?

  • I have had problems with this internet from day one. It intermittently cuts out and their techs they sent out haven't helped neither have their customer support at their call center. I keep getting problem loading page messages saying server not found. When i refresh a few times it works(sometimes). Downloading is a pain so is You Tube. I've updated network drivers but they don't help. My connection is a cord straight from the modem to my desktop port. Often i see the connection as working but the internet still doesn't. Diagnosing and repairing my connection provides only temporary relief. I have Mozilla and am using windows vista sp2. Comcast is the only high speed internet in my area so if i cant get it working I'm screwed.

  • Answer:

    Are you using your own modem or are you leasing it from Comcast. Assuming you are leasing from Comcast, they test everything up to and including the modem. If they say their side is OK, then you need to start checking your system. Here is the order I would use to troubleshoot. 1. Replace the Ethernet cable 2. Try using a different Browser, an or uninstall and re-install Firefox 3, Download Ubuntu from the Ubuntu website and make a CD. Reboot the computer using the CD Use the live CD option ("Try Ubuntu") to use the OS without making changes to the hard drive Once it loads (It will be slow because everything is running on the CD) you will be able to use the version of Firefox supplied with the OS and the Linux Ethernet drivers to get on the net. Try that and see how it does. If you see a marked improvement, then the problem is Vista If nothing changes, you have a hardware problem 4. If it's hardware, get a new Ethernet card. 5. If it's the OS, you will need to upgrade your OS. Best of luck

Depending on how many devices you have on your cable network (cable boxes and other devices) and the distance of your house from the street connection, there's a good chance that your incoming signal is weak to begin with. The more devices you have, the more signal is dropped over the network, and the weaker it becomes. If you also have dirty power in your area (brownouts or fluctuating voltage) it also affects the devices carrying the signal, and with voltage fluctuation also comes signal fluctuation. The easy fix for a weak incoming signal is an AC powered cable line booster, which can boost your signal at the point it enters your house by 5 or 10db. In my own area, even though the street connection is close, the incoming signal is still weak enough that I've used a line booster to compensate for about 11 years. I also have quite a few devices on my network, but the booster eliminates any signal fluctuation. As far as power fluctuation, the only way to deal with that is to hook up your system and modem to a UPS with a voltage regulator. I use them on all my house electronics, including my systems, network devices, TV's, etc. Though I have a 1500VAC APC UPS with voltage regulation (AVR), I have several Tripplite 1000VAC UPS / AVR's hooked up to my network systems (modem, router, etc.) and smaller electronics. Motorola makes a pretty good booster - always get an AC powered one, as the inline transformer types don't work as well. http://www.amazon.com/Motorola-Booster-484095-001-00-Bi-Directional-Amplifier/dp/B000066E6Y Tripplite UPS/AVR - http://www.amazon.com/Tripp-Lite-SMART1000LCD-Digital-Line-Interactive/dp/B000B651DO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1299383423&sr=1-1 If you run the cable through the line conditioner on the AVR, it will further clean the signal coming through the cable line. The line booster is installed at the point where it enters the house, but before the cable splitter.

First of all the internet is the internet. It's not comcast's or anyone Else's. Number two you should have firewall/router between your desktop and the modem. Do you have the same connection issues with Internet explorer or chrome? Firefox sometimes gives "server not found errors" usually reinstalling it will fix it.

It sounds like you might have a problem with your cable modem or connection. You didn't specify the brand and model of cable modem. If power cycling your cable modem resolves the problem temporarily, it may be failing. Comcast Internet is usually fairly fast and reliable in most areas Most DOCSIS compatible cable modems have status screens that are accessible from your browser. These screens will give you valuable troubleshooting information such as signal strength, noise ratios, etc. For many cable modems the IP address is http://192.168.100.1 Here are a couple of screenshots of my Motorola SB6120 cable modem. http://isp1.us/img/sb6120-signal.jpg http://isp1.us/img/sb6120-status.jpg Take a look at your modem status and check the raw speed at http://speedtest.net This information will help in resolving your problems. Good Luck
