[Connectivity] I have a TM822; should I install it?

Hi all,

A while back I got a note from Comcast telling me I should order a new cable modem for better Internet performance, so I did. Recently, an Arris TM822 arrived. When I opened the box, I got nervous when I saw that it is called a "digital Internet and voice modem." Voice? I don't want to be messing with my Comcast phone stuff: that hardware is all in the attic and its wired to phone lines thou out the house. So, my questions:

1) can I use this thing just as a cable modem without messing up my existing Comcast phone solution in the attic?

2) should I switch to this modem anyway? For some reason, I have a bad feeling about this thing, like its going to take me forever to get it to work. I'm thinking "if it ain't broke..."

Thanks!

Doug

you can use it as a hsi only modem, but you still might have problems; odds are its stolen. where did you buy it from? you didnt notice it was a phone modem when you bought it?

Sorry, I should have been more clear. I got it from Comcast by responding to the notice they sent me. It appears to cost $7 per month.

If you already have a Comcast Modem in your attic that is being used for your phone service, what is the make/model of that one?

Another question: Since you have HSI, are you using that modem in the attic for that as well, or do you have a 2nd modem in your house? If you have 2, did you purchase the HSI only one yourself, or are you renting both from Comcast? Also, on the 2nd modem, what is its Make/Model?

Just trying to figure things out here is all.

Doug, I can see some confusion here.

It sounds like you are saying that your Comcast phone service is being run through a separate emt modem in the attic...is this correct?

When I initially ordered Comcast (self-install) kit, it came with both a regular cable modem, as well as an emt (internet/telephony) modem, in case I was going to hook up the phone line at a different physical location than the internet (I did not, and did not need the cable modem, both my phone and internet go through the emt modem)

If that is your case, while you can use the TM 822 solely for your internet, Comcast probably assumed that you needed an emt modem, and that's why they sent the TM 822. They probably should have just sent you a cable modem.

1 No no you cannot, they will try to convince you they can make it work but the computer system will screw it up at least once in your life time if not once a month.

2. NO, return it to the cable store,, mail it back, or have a tech come by for an eq swap and have them give you a standard just HSI modem. If you want wireless, that thing sucks for it anyway, buy a real router.

The TM 822G is not a wireless gateway, so that would have nada to do with wireless performance.

It may be a good idea for the OP to switch it for a straight cable modem however, if his Comcast phone service is already running through an emt modem in the attic as it sounds like it might be.

this is simply a docsis 3 modem/phone equipment that allows the equipment to bond to all 8 channels and get the speeds you need . You can use this equipment just as a ((((modem)))) AS LONG AS IT IS SETUP THAT WAY!!!

So you are saying that you are already getting Comcast voice, and the modem is in your attic?

If this is the case, it is just a matter of swapping out your existing phone modem with your new one.

If they contacted you, it sounds like you probably have an end-of-life device, and it is likely a very old model.
I'd swap it out if I were you.
All you have to do is plug it in instead of your old one, and contact Comcast to activate the new one.
You will likely see much better speeds.

he has a seperate phone and HSI modem, basically they sent him an EMTA to do the HSI, becasue they are a third party company contracted to do the mail outs and they saw CDV and went that route without reading further to see he has 2 separate devices. What will happen is at some point the system will try to move all services to one box, either HSI to the one in the attic or phone to the one he has now. When it does this he will have to call in, try to get a phone rep to understand something they have no knowledge of, and end up getting dispatched a tech who may get it fixed, only for the computer system to do it again at another date.

Some designs are just bad from the get go, this would be one of them. I go to these calls all the time. I end up runnig a new phone line if they let me and putting one eMTA in where the computer is to do both.

As to the 822, yeah I misread it as the dory [TG 862] model not paying enough attention.
