comcast modem will not get on the net, sometimes?? is the tech full of crap?

Recommended Posts

My modem will sometimes not allow me to use the net, but if it is unplugged and plugfged in sometimes that will allow you to get back on. Other times unplugging does not work and I have to go into my computers network connections and perform a network repair. This will work until it happens again. The Comcast guy said it is because I have the signal split to 3 TVs in the house. This sounds like bullshit. I pay for high-speed and cable I should be able to use both regardless if all my TVs are on and the computer flawless. Is he blowing smoke up my ass or what?

Thanks in advance!!

He could be right.. depending on the type of splitter.. the signal could be dropping enough through that 4-way to cause problems.  I had the exact same problem when I first got my comcast.. I went out to home depot and bought a 3-way and installed it and lost my internet.  a tech came out and installed a better one.. I know that ca3le posted on this topic before including what type to buy.. might do a search and see what you find.

If by your description, you have 3 TVs and a cable modem, then you need 4 signals.  To get the best connection to your internet, get a 2-way splitter and a 3-way splitter.  Put the 2-way on the line coming into the house, send one of the lines directly to your Cablemodem, the other line goes to the 3-way splitter.  Now run the lines from the 3-way to your TVs.  This would be the most prudent way to check to see if the problem is in your wiring.

I understand how splitters can slow down internet a little, but here is the deal I ran this setup without problems for about 1.5years. It just doesn't add up to have a problem now. I wish I could run a separate unsplit line into the house from the original source like stated but it is a two story house and has almost zero attic space. i am willing to sacrifice speed from splitting the signal, but I should be able to connect to the net regardless if I had 12 TV's, thats why i pay for both internet, and cable T.V

Thanks alot guys!!

Badasstang90, try loggin into the diagnostic page for your modem.  Usually, type "192.168.100.1" into the address bar of your browser (without the quotation marks).  Post your modem's signal levels here, and we can interpret them.  Sounds like you may be dealing with a hardware or line issue.

Another possibility is that you may call your ISP to have them check your modem's flap list.
