I replaced Comcast modem to save rental fee each month. It took about 15 minutes to setup. It's been in use several months now.

Purchased this modem rather than paying the 5 dollar a month rental fee from TWC for a similar modem. I have their standard internet plan and have had zero trouble.

Noticed my cost from Time Warner for internet went up and spotted the modem lease fee at $3.95 a month. Figured out that I could provide my own modem from their approved modem list.  This unit is on the list.

Ordered a used one delivered via Prime for $18.00 - great deal.  Plugged it in, called Time Warner, gave them the MAC ID (see the bottom of the modem) and I was up and running in just a few minutes with no change in speed.

No issues with my wireless router (Cisco/Linksys E3000) or my network switch and all my devices connected as if nothing changed.

In 4.5 months I will recoup the cost of the modem and will not have to pay the lease fee again.

Not that $3.95 is a lot of money but its a small victory over the continually escalating costs for internet service, satellite tv, mobile phone service and satellite radio. Love to work these guys for a better price since they always try to nickle and dime you to death.

I purchased the used version instead of new from here on amazon. After having it for several months, I noticed a Modem Lease add on amount on my Comcast bill. It appears this modem I received was STILL leased by Comcast. Now I get the pleasure of trying to prove I own this modem, so I can keep from being charged the $7/month extra.

I should have done this awhile back & quit paying rental fees!
I got my own router a couple years ago, and am now adding this modem (it is just the modem).
I researched &  chose this one because it offered what I needed at a good price, nice compact size, set up sounds simple & is Comcast compatible.
Yep..all true.
I plugged everything in and then contacted Comcast. This modem IS on their accepted list, and the Rep had me up & running in minutes.
A HUGE BONUS....my internet speed has really increased since I hooked up this modem!
Glad I picked this one. It's working just great!

This modem is the EXACT same one that I was leasing from Comcast at $7 a month.  Old modem returned and this will pay itself off in 7 months.

Once you get it plugged in, call Comcast and tell them that you OWN a new modem (my rep got confused that this was another one I got from the Comcast store).  Once they get that straight, give them the MAC address and they will ping it.  Also, if your PC is behind a router (as mine is), you will want to plug a laptop or something in directly to the modem line and bypass your router as Comcast will make you do this for testing.  Do this ahead of time and you won't have to waste 5 minutes as I did.  One last piece of advice, when you return your old modem, GET A RECEIPT that you returned it.  I haven't had an issue, but it wouldn't be below Comcast to try to continue to charge you the $7.

I should have done this YEARS ago!

**** UPDATE ****
Comcast just doubled my speed and the e-mail I received from them stated that some modems would not be able to handle the increase.  I am happy to say that my modem is now handling 40Mbs DL and 15 UP with no issues at all.

I purchased this Modem to replace the modem that I was "renting" from Mediacom cable company.  I have cut my bill by $10 per month.  I will have amortized the cost of the Motorola Modem in four or five months.  Setup was simple and one call to a competent technician I was up in running in no time.

Worked great with local cable provider.  Speed is exceeding what I expected.  Saving the cost of the monthly modem rental it will pay for itself !

Time warner cable was charging me $4 a month for their modem, I bought this instead for $20 and it was definitely worth it

To avoid Time Warner Cable's new modem rental fee, I bought this one to replace their modem.  The process was pretty simple, I just had to call TWC and give them the MAC address of this new modem so that they could activate it on their network.  Apparaently a lot of people are doing this, as I spent about an hour on hold.  However, once I got to talk to a CSR, it took them just a couple of minutes to activate the modem.

This modem provides me with more consistent internet speed than the TWC-provided modem it replaced.  I pay for a 20 Mb/s, and used to see fluctuations from 11 to 25 Mb/s.  This modem consistently provided a connection at about 19.7 Mb/s, just shy of the maximum speed I pay for.  I recommend this modem to anyone looking to avoid TWC's new fees.

In October 2014, I purchased a used modem from Alteko to replace the Comcast rental modem I had.  It installed cleanly and has worked fine for about a month so far.  I am using it for internet use only (as opposed for use with Comcast telephone service -- I use VoIP for my "landline" phone service.)

4/20/15 Update:  Purchased a second used modem from Alteko to upgrade my parents' Comcast internet/telephone service in the Eugene, Oregon area.  Installed easily and has been working fine for a few weeks. // The first modem I purchased for myself continues to work fine.

This is the same model I was renting from Comcast for $7/month. Setup was super easy. I just replaced the rented modem with this one and when I tried to connect to the internet, I was redirected to a comcast webpage where I just had to enter the MAC address (from the box) and it worked instantly.

We leased fromMediacom ($16/month) and went thru 4 modems in 3 months and the service in between did not work consistently. Two months with this router and I have no issues. So save money and consistent internet. No brainer

I decided to buy a modem after I saw my Comcast bill had gone up (again) and it was in part due to them raising their modem leasing fee from $3 to $5 per month.

This modem is almost the same model as the one I had leased through Comcast.

Installing it was easy.  The only real difficult part of the whole thing was being on hold with Comcast for 45 minutes - and never speaking to someone.

Be forewarned that if you get your cable internet through Comcast that you may have some "down time" - you have to give them the MAC address listed on the bottom of your modem and then they will probably tell you it could be up to 24 hours before they get it processed and you are able to get online.

Now this is a review of the modem, not Comcast and I have to say that the modem has been running perfectly and it is going to end up saving me money in the long run.

My advice if you have to deal with your internet provider is to plan to install your modem when you do not need to be online again immediately.

I have had no problems with this modem since installing it one month ago. It works with Comcast to allow you to drop that $10/month charge. It was "easy" to set up; took about 15 minutes on the phone with Comcast (by Comcast standards incredibly short). I would recommend this to friends and anyone that wants to drop their monthly modem rental fee. I have it paired with Medialink MWN-WAPR150N Wireless-N Broadband Router and haven't had any problems so far in a one-bedroom apartment.

I bought this modem rather than paying 7 dollar for renting the devices from Comcast. It works very well and it was almost new when I received it . :)

Having a combination Modem/Router saves me $10 a month on my Internet bill.  I also like the ability to plug into the back or use my laptop remotely.
