I did the same thing. It was just a bad modem. If you are near an office maybe try to get a trade.

 

i dont know if they would do that. i ordered the modem online through one of the websites that they work with. i paid full price but get it all back when the rebates get processed. made more sense than to lease one. if it is a modem i hope they take it back so i dont have to deal with the return process.

 

you shouldn't split the line too many times before it gets to the modem. Each time you split it, it degrades the signal. You'll notice this especially in your T.V. signal. Use quality splitters, the kind that split the signal evenly....(some are designed not to). I had to play around with my setup before I got full signal strength on all T.V.'s plust fully functional Internet....It was all new to me when I did it...I screwed it up the first time using the wrong splitters,...then the ones I used just sucked,...after going to home depot and buying the good stuff everything worked out just fine...lol.

 

Damn, that's a good idea, I should swap out all my splitters to better ones. My sister's TV's getting some crap reception from channels 2-18 or whatever. Good to know. I thought I was always stuck using whatever crap Radioshack sold.

 

I would try plugging the modem in to the line that comes down from the pole. If it doesn't work there, you tell comcast to suck it, and come out and fix your ****.
Remember, they say they want you to be happy customer, but it costs them fore them $50 to send someone out onsite usually to trouble shoot a problem.

If you can prove that you get no sync, or connectivity at the Main Point Of Entry(MPOE), then Comcast is responsible for fixing it.

good luck.

Also, what is/was the loop distance for your DSL? if its 15K or less, then you should be fine, if not then the ILEC should be looking at line interfearance, loop length mismatch, or they need to upgrade their hardware.
My loop or line is 14,300~ ft. from the CO and I get a solid 6000Mbps down/700Kbps up.

 

i tried connecting the modem to the main line and still nothing. they're coming out tomorrow to check it out.
as for the dsl... when i first signed up i was told that my distance was around 13,500 feet. i never got good service so they ran an actual line test and found my distance to be around 20,000 feet. sometimes i would hit 700down/256 up but very rarely.

 

SBC or Verizon? SBC sucks donkey nuts and they tend to have their head up the ***.
Try someone like dslextreme, I found their provisioning department makes sure that SBC does it right.

 

Well let me start out by saying I love my Comcast ISP. I don't call them much since I rarely have any issues.

Your cable coming to your house terminates to the outside box "MPOE" Miinimum point of entry.

If you have Comcast cable TV they require an inline spliter to be installed there.

From that point it is a straight run to your Cable Modem.

From the RG12 "Coax cable" in your wall it goes straight to your modem.
From your modem it goes straight to the NIC "Network interface Card" on your PC.

What I would do:
Forget plugging in your PC for right now.
Simply plug in the modem and turn it on.
You should have a link light and power light but no activity light as you are not passing anything through it.

Plug the modem into the PC and install the software. If you are unable to connect then Call customer service and have them try to detect the modem.
If they are unable to then they will need to send someone out. It is important to remember that if you don't have a link light focus on that with the tech as saying your computer isn't working is not a modem issue. They person who comes out can tone out your cable as depending on the age and distance from the empoe it might be bad.

I have a Cisco firewall that I run so I don't need to install any connection software. Linksys also makes a nice firewall for DSL / Cable connections that isn't expensive.
I HIGHLY recomend this to anyone with an always on connection. I have done tests and unprotected machines, even those with software firewalls start picking up junk within 48 hours of being connected.
Only caviate to this is you will ned to follow the MAC setup instructions to setup your user name and password, email prior to setting up your firewall. You go to an SSL web site and register. Then simply plug in the username and password settings on your firewall and away you go.

When I ordered my service I got free installation even though I am technical I wanted to make sure they checked all the cabling up to the modem.

 

Well fine, fix my one little mistake! ;P

When I worked at DSL.Net that is what they called it. :|

+1 for the home router/firewall suggestion, it amazes me how many people do not have these.
