Firmware is the software programmed into your modem that makes it run. Occasional updates are important to add new features and keep the modem's performance at its best. In many cases, your modem will install updates automatically. However, if your equipment isn't performing properly, it's worth checking to make sure the firmware is up to date. You can do this through the Utilities section of your modem's online settings.
Before you start, keep these tips in mind:. NOTE: Depending on your model, your modem's user interface may appear slightly different from the images below. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem. You can find the Admin Username and Password printed on the sticker attached to the side, back or bottom of the modem.
The modem sticker shows you TWO important sets of login credentials. How do you use each one? Admin Username and Admin Password: Used to log in to your modem settings portal. Select "Upgrade Firmware" in the left sidebar. Check the "Upgrade Status" area. Select "Download. Select the drop-down next to "Save" and select "Save as. Select "Desktop" or choose another folder if you prefer , then click "Save. Next, to install the file you just saved in the previous step, select "Browse" on the Upgrade Firmware screen.
Navigate to the folder location on your computer where you saved the file in step 9. Select the firmware file, then click "Open. I currently run a phone and an 8 way wired router off my modem with another wireless router. This supports the 7 or 8 computers we have in addition to smart phones and kindles. Xfinity had an offer to swap my modem for a newer faster one. The switch should have been seamless. Just 3 simple connections, the phone jack, cable and internet connections and reboot the router.
There is also an automated number to reconfigure. Well after many hours of phone calls and needless waiting I finally gave up and just put my old modem back in. I worked in DP programming my entire career and for the life of me all these guys are good at is developing automated and confusing answer menus.
There must be a better way to upgrade a modem. We have d-link right now and I think it is losing its power…. I am not a tech person:- We have a comcast modeum, what would be the best to do, get our own modeum with a new router, or get a gateway through comcast…..
Got them to back down on the phone connection, but they never gave on the internet. Thanks for the helpful tips and links and advice, etc.
I just recently got my first apartment and signed up for Comcast. Since this post is from last summer, do you or anyone else have a sense for how much the technology has changed in the last year? Is the equipment you mention in the post close to being obsolete, or, if I purchase it now, will it last for a few years?
I tried doing what the article by G. Miller said to do and was totally blown off by Comcast. I finally decided to put the Comcast modem back in service until I could get to a Comcast service center to return their modem. I will put up another posting after I complete that. Not sure about phone — but it works with internet. And cable runs off a cable box, not a modem. Comcast phone is a ripoff — get an Ooma instead. Thank you so much for writing this article. I have been on the phone with Tech support with comcast for 3 days in a row now.
I am paying for upload and download speeds of 15 and 20 and I am only getting. Of course at first they said it was my own fault and it was my equipment that was faulty. When I abosulely refused, she then said that the modem they installed at hook up was out dated the day they installed and they are gonna send a tech guy over here to replace it with the exact same modem that is outdated. So after shedding many tears, talking to my tech savy son and doing an internet search I found this article.
Thanks again for all the information that this article has provided me. BUT beware you may have issues going forward. It took 3 hours total time on a saturday. So, do your research and your numbers too to see if is something you can afford or not. No need to pay more.
I just got this badboy yesterday and will replace mine tomorrow! An Ooma has a phone jack, and when paired with the router I have suggested in this post, you should be all set and save lots of money. I wonder if anyone had this problem. Signed up for Comcast tv and internet. Installed two cable boxes and one wireless tc connection.
So I had to reconnect the gateway and get charges put back on my bill. Do u know anything about it? Thank you. Just read the Ooma review, one question.. I asked Comcast about this when they signed me up for triple play and they told me they actually have mobile trucks that would be dispatched to keep the VOIP network running in that situation.
The land line is really just for emergencies for us since we use our mobiles pretty much all the time. I have the TG from Comcast. Assuming it is not good enough anymore. Am I right? After viewing the list of Comcast-compatable modems, I bought an Arris TM modem for cheap on eBay to replace the one I was renting from Comcast several years ago. It does not have wireless capability, but I have a stand-alone wireless router to support it.
The modem paid for itself in just over one year. All I really watch on my current package are the HD channels and nothing else.
OK I did it! Registering was a snap, took 10 mins total with a rep online. My laptop connected directly to the modem I get But through my wireless I only get 9. But just happy I replaced my old modem with this new one. My family put up with it for three months after agreeing to take it after negotiating a lower monthly rate. What a mistake. I had an angry wife. Not a day went by without having to reset this P. Comcast has great bandwidth in my area.
I do not understand why they want to blacken their reputation by providing this junk 3 in 1 gateway. I bought the recommended modem and router from Amazon last Friday and installed them Tuesday.
She is a great service person. Bottom line. This set up is the fastest problem free wireless that I have ever had. Happy Wife…Happy Life! Thank you for your article! So can someone tell me? I assume you also have voice through Comtrash?
Read my earlier post in this thread since I ran into the same issue and just went with OOMA for my voice. Comcast is sketchy. We just purchased a new Arris modem.
These cable companies need to be investigated- Just like the guy above when they deleted his modem information out of the system as to drop his connection when he bought his own modem- ridiculous companies.
I want to try getting my own cable modems and OOMA. No — not forgetting anything. Plug and play — works flawlessly. However, I also have phone service through Comcast and the previous modem I was renting from them had my phone cable in addition to the ethernet cable connecting to the back of the modem.
Do you have any recommendations or solutions to this problem? I just want it to work again! Get an Ooma. It plugs in to your router phone plugs into it and works just as well, at a fraction of the price.
After careful consideration — and counting costs — I finally decided to get an Ooma and dump my Comcast phone line. Hi- I just wanted to tell you that I replaced our troublesome Comcast gateway with the Motorola SB yesterday I followed your instructions to the letter and they were spot on!
Everything — including my call to Comcast — went exactly as you described. And thanks for the tip to go directly to technical support. We had internet in less than 5 minutes. Thanks so much! So it turns out the call quality on my ooma seems to suck according to my wife, had it since August So she wants to ditch the ooma return to Costco and go back to the comcast voip which we still pay for since we never cancelled our triple play package.
I just replaced my comcast modem. Quality on my Ooma is great, so maybe you just got a defective one? See if Costco will do a switch for you before you go back to Comcast.
That should be last resort. Something like this. Plug one port into your modem and the rest of the ports are free to use for whatever devices you have pc, ooma, wireless router, etc. Great comments on this site. Just got my latest Comcast bill, and everything has increased. Performance is actually good, and I have wifi on my laptop, iPad and iPhone without any problems.
Plan on visiting my local Comcast center this weekend to discuss all these new peripheral charges, and wonder if I should discuss with them my plan to replace their product with a separate modem and router. Just looking for thoughts, I guess!
Rip off that Band-Aid! Same as Tiajo, I saw my bill everything went up. My regualr cable fee is included with our association fee. Beside that I have Home Infinity alarm,voice and internet. What modem is capable with the comcast one. Please advise. I want to change as soon as possible. Hi, I read your article last year, and was ready to get rid of the Modem monthly fee, but when I looked at what it was that I needed to buy, it said that if I have the comcast phone service that it would not work?
It is working as my number was already ported did not want to change phone numbers to Comcast. I will say, G. However, I am looking for a slight variation of your method. I do, however, use Charter Communications. I thought they were bad! Well, they are. I gave it to my mom, because where she lives, WiFi is the only solution when she uses her cell in the house, or around the exterior.
It works fantastic, too. What I want to do is swap my SBG with her. My problem is: How to connect the SBG to the modem she has already. The coax plugs into the modem and outputs to a router, as well as the phone. So WiFi is now my only alternative, at home.
The Motorola is just not worth a damn, where the WiFi is concerned, although the Ethernet is quite good. What I am hoping for, is likely impossible. Which brings me to the reason for this post, other than giving you a well deserved thumbs-up, for your contribution!
Diaablo had mentioned that, after using the Ooma for about a year, his Mrs. Cell phones certainly dominate with consumers, right?
Well, it seems there are still a huge number of people who prefer both. Your Home Network. Xfinity Community Forum. Netgear says I cannot update the firmware on my own, that Comcast will have to push it. Current firmware version is v 5. According to Netgear Comcast has v6. I've tried talking with an agent on the phone with no luck. Tried asking them to escalate, with no luck.
