Charter is my ISP. I use a modem that they supplied and installed, along
with a linksys router. It is attached to my Dell 2400 desktop. I have two
laptops. All computers use XP HOME.
I was paying $3./month for the modem. Charter has now raised that to $5. per
month.
My question is: can I just return the modem to Charter and buy one that will
work just as well with my linksys? If so, can you recommend a brand/type.
Would it be easy to install? What would the price be? Would I have to
re-program the router (in terms of security settings, etc.).

Yes. You may wish to call Charter and ask if they have a list of modems they
would recommend. If they do not, search the web against the model # of your
current modem to find out what standards it supports. Buy one that
advertises similar specifications. (Usually not a problem, as nearly all
cable modems are expected to be what is known as DOCSIS compliant.)
> If so, can you recommend a brand/type.
Although I do not believe it is marketed any longer, I've been very happy
with a Linksys BEFCMU-10 cable modem. Their newer modem offerings should be
similar.
> Would it be easy to install?
Yes. The longest part will be getting through to Charter, to tell them the
MAC address of your new cable modem. (Every network device has a MAC (unique
hardware) address "burned in" at the factory.)
Other than that, just connect the cables, turn the modem on, and then you
can get on the phone with Charter.
> What would the price be?
About $70-90 depending upon features and where you buy from. I have not
noticed a lot of variation in price.

etc.).
That should not be required, as the router can continue to do its thing. All
you might have to do is power-cycle it after the modem comes up.
Thanks for the quick response. I called Charter and they said it just has to
be docsis 2.0 compliant. I then checked on BUY.com and found this
refurbished Linksys. What do you think?
Also, how do I get the MAC address that I have to mention to Charter? I
gather that I don't have to communicate this address to my router?

When it arrives, call Charter tech support and give them the MAC number that
is on the sticker on the unit. Then plug the power supply into the unit, and
the ethernet cable in your current router (same connector as the Charter.com
cable modem is connected to). You should not need to use the USB cable or
drivers included with the modem.Once the modem is up and running, I would
wait a week to make sure that all is running as expected, then return the
Charter cable provided modem, to a pay center near by, for credit.

Mel,
My experience matches the responses of others here. One of my good home
office customers had the Charter-supplied cable modem fail. They were
told by Charter to bring the modem to the nearest Charter office, 25
miles away, for an exchange. Both adults in the family work long hours
(who doesn't?), so an exchange was impractical.
They called me instead, and I sold and installed a cable modem I keep
around for times like these. I called Charter tech support, gave them
the MAC address of the cable modem, after which the Charter tech waved a
magic wand and the cable modem was operational. Been that way for two
years, and no added monthly payment to Charter by my customer... Ben Myers

That is usually the case these days. Most any recent modem on the market
will meet the requirement.

I don't know precisely about the CM100 from Linksys. I have the BEFCMU-10
model and have been very happy with it. I doubt there is a lot of difference
internally. If you are OK with buying a reconditioned modem, I'd call that a
pretty good deal, as it is a fairly new product.

The MAC address is printed on the modem itself (and labeled as such) as well
as on the packaging itself. Since the MAC address of every device is
supposed to be unique, the cable company maintains a list of addresses that
are allowed to get on their network. That is why they have to know it. It is
a number that takes the format of XX-XX-XX-XX-XX-XX.
I trust your customer eventually returned the modem to avoid paying the
monthly rental fee!!!

I read some reviews and folks are commenting on the increased speed of their
new modems (compared to the ISP modem).
Could that be true?
Should I expect a speed difference with a new modem?

I'd doubt it, unless the old modem was held to an old enough revision of the
DOCSIS standard that it could not communicate at the highest possible speed.
Or, maybe if the modem was of poor quality or attached to a USB port
(instead of Ethernet). Cable modems do have an onboard processor, miniature
operating system and some memory, but even the puniest of modern embedded
CPUs ought to be able to keep up at current cable data rates.
Cable companies send parameters to cable modems (such as the maximum
permissible communication speed) via TFTP when the modem starts up. If the
modem has a clock (and many do have at least a software clock) it is usually
set at that time.
It used to be that cable modems would accept TFTP settings file downloads
via either the cable or Ethernet interfaces. This led to people making
'cooked' settings files that would--at least in theory--allow their cable
modem to communicate at faster than allowed speeds. Cable modem makers were
pretty quick to close this loophole in newer hardware and with newer
firmware for many existing models.
> Should I expect a speed difference with a new modem?
I very much doubt it, unless the old modem was of poor quality or
malfunctioning.
Ok, that's what I thought, but as I said I read some user reviews that
mentioned a significant speed increase.
Anyway, I did order that "linksys certified" refurbished modem. It was
$27.99 delivered.
