  • A. No - and you should never plug a computer directly into the modem - you are a sitting duck on the Internet, open to all kinds of automated port scans and other hack-attacks until you put your computer (or network) behind a NAT router. It's not a total security solution by any means - but to a "hacker" on the other side of earth - it's much better to have them stopped in their tracks at your router than able to directly access your PC . Since practically all of the home routers run some flavor of Linux (not Windows) - the Windows vulnerabilities hackers use to exploit ports on your PC become irrelevant. Note that it's possible to protect yourself without a router but you'd better understand the ins/outs of a firewall or other advanced security appliance - and know how to deploy it.

When I learned I was paying Time Warner Cable $7 a month for a DOCSIS 2.0 modem (no longer in use) for many years and could purchase my own - I did. I followed the "where to plug in the three cables" instructions (cable company line, ethernet line to router and power line). With my computer and modem on, I called "TWC technical support" to give them the MAC ID number on the side of the unit. The TWC rep "set up" my new modem and removed the monthly charge. The entire process of hooking it up and finishing with TWC was less than ten minutes. I took longer to hide the new power cable behind my desk. Ordering online is a few bucks cheaper than purchasing in the store (and cheaper than Best Buy, Office Depot and Frys). My Walmart is a few blocks away so I had mine shipped to the store. They emailed me when the modem arrived. Walmart has a special line for "ship to store" pickups - so no waiting in the "merchandise returns" line. I will never pay a monthly modem fee again. So far, so good. Thank you Walmart.

This is my second purchase of this model. First one 6 months ago is at home and this one at my son's college house. Both needed to be Comcast compatible and DOCSIS 3.0 to be future proof. They are fast, and easy to set up after the required call to Comcast support to allow them on their network. My only complaint with the modems is every once in a while they trip off and restart for no reason. I have not researched this issue yet, because it is very brief, albeit annoying. Another complaint is with Walmart's stock reporting system. My second one's online purchase confirmed in stock status, but none was at the store when I arrived, the out of stock text came while I was leaving the parking lot. So, I cancelled that purchase and ordered it from a store near my son's house, which also showed it in stock, but a text came saying it was on back order a few days. There is definitely a problem with Walmart's stock inventory network and its communication with their online store.

I am not enough of a tech. to know or use all the features but for my 4 lan and 3 wifi house it works perfectly. The modem set itself up and got on line with Comcast automatically. I had to fill in a few questions about my account on line and then it was up and running. I did call Comcast tech support just to make sure all was well and the operator confirmed that the Motorola SB 6121 had setup automatically. My old Zoom modem worked great for 4 years but then Comcast changed something in their system and it began to drop the connection. Comcast, of course, wanted me to pay $8/month to rent one of their modems. Buying my own from Walmart for less than $80 made more sense to me. The Morotola SB6121 is rated one of the top compatible modems at the Comcast tech site. In another 3-4 years some other change may out date this modem but by then it will have paid for itself 3-4 times over. I guess I need to put the Zoom on craig's list.

I decided to purchase this modem after our previous Motorola SB5100 began having sync issue. After spending nearly an hour troubleshooting our connection issue with cable provider, I was offered a replacement through them at a monthly lease charge of $6.99 a month. For that amount I justified the cost of this replacement and avoiding the monthly charge. Setup of the Motorola SB6121 was easy and straight forward. A 10 minute phone call to cable tech support to switch out the equipment and we were back up and running. Our internet connection is a 30x5 we were averaging 19x1 with the old modem. We now are getting 30x4.3. The added feature of the multi-speed Ethernet port is nice. If your Router WAN Port is Gigabit capable, the lag when connecting and downloading is gone. The modem is great for those who stream video, music, and online game. It also resolved a lag issue when streaming content from our DirecTV dvr.
