What will be required to swap modem (spare)?

New service (50/10), using Motorola SB6121, up and working fine, have done a major upload to get my photos backed up off site, speed consistently good and to spec over two days.

 

I keep spare equipment configured to swap as I travel a bit and wife is here, so I have a spare router, etc.  I was going to get a spare, matching SB6121 modem also (I own, not lease).

 

If the modem needs to be swapped, is it just a matter of plugging it in (doubtful), or do I need to do something to activate it with the new one and its mac address?

 

Is that something that I can do online, or do we need to call to do a swap (I would actually like to swap when I buy it, so I know the spare is OK).

 

One reason for the concern -- the installer was not able to do the install with his laptop.  He claimed my SB6121 was bad, then used one of his own -- which didn't work either, a different brand.  He tried to get a remote activation of his, failed.  I asked him to please try remote activating (pushing, whatever the right term) mine, it worked, he said "good" and left.  So I am a bit concerned about making changes and whether it is fully set up right as well.

 

Recommendations?   Get one, put it on, call for help to swap to make sure?

 

But just FWIW, so far can't be happier with the connection, have monitored it carefully and so far nice and solid and steady performance with vary large file transfers.

 

On a related note -- shouldn't my account page show a usage meter?   Am wondering how my measurements correspond to it's?   About 200G in two days uploaded -- that's it, now my usage drops nearly to nothing, but wondering how they measure.  Yes I know about the policy change, but thought the meter was still there in the account page?

After you change modems, when you try to go to the web you'll be redirected to an activation page. You'll need to know your Comcast account number, the web page handles the rest automatically. It takes 10-15 minutes to activate the new modem. Occasionally this doesn't work, then you need to call Comcast and give them the modem MAC address, and they can activate from their end.

 

Regarding the missing usage meter, you can call Comcast and ask them to "roll and reprovision" the modem; that's the usual fix. On the other hand, considering the problems they had provisioning the modem in the first place, I'd be worried that this could break things again.

If you don't see their automated modem registration page in a browser when you first connect a new modem then you will need to call in and tell them that you want to have a new modem provisioned for service. Have the make, the model number, the HFC / RF MAC address and the serial number handy when you call.

Didn't see your response before I posted Barmar.

Yeah.  The guy was very nice, a but hurried, but my impression is neither he nor the people on the phone really had any idea what the problem was, or frankly why it worked when it finally did work.  Incidentally his comment was that the modem (the SB6121) would reboot (and I did see it) everytime he tried to activate before he could even key in the information.

 

But it has not rebooted a single time since (and I had let it burn in, not connected, a couple days before he got here without a reboot).  So it was some aspect of the activation attempts that caused it.  Or his laptop, which is a good posibility.

 

I guess I won't worry about the meter too much, I have good reporting on DD-WRT in the router, not quite the same but I assume 10% or so overhead added to it ought to be about right.  And besides, they aren't really enforcing now anyway.

 

Thanks both for the advice.  I think I'm going to leave a new one sitting on the shelf, and activate it if I need to fail over.  I'd say just wait until it failed to buy, but availability of non-wifi versions is a bit spotty locally, as well as what they carry on their trucks (according to him).

Interestingly this afternoon the usage meter appeared without me doing anything.  It appears to have missed the first couple of days, which is good.
