Modems

Can I use a battery in my BGW210 AT&T modem, if so, where can I buy one?

Our Surfboard T25 disconnects from the internet, reconnects for a while when rebooted, then disconnects again.  We disconnected the T25 and re-installed our old Motorola (slower) modem and it works fine. P/N 613587-003-00

Hello!I recently got this modem/router from my internet company.I am trying to log into it for purposes to turn off the WiFi part of it so I can use an Eero.Normally I am used to “admin” “password” or a varietion of capital letters.However no matter what I try it does not work, I have called my company it doesn’t seem like they know any other ways.I have tried  admin and Admin, password and Password. I have tried the P/N, the preshared key, the S/N and the WPS PIN.  None of these work.I read around that maybe directly connecting it to the ethernet will allow me to get in, which I’m about to go get one from Best Buy.  But I do not like the idea of not being able to get into my own modem, so if I could get any help. P.S. I have restarted it, I have reconnected all cables, I even pushed the reset button that is hidden on the back.

When I click add device, it only lets me choose surfboard mesh or 6GHz devices. 

I just received an Arris DG860 router and can't get it connected because I don't know the password. Where do I find it?

Please help me rename my modem and change the password 

Hello,I am trying to host a small panel server on my internet, and when I port forward, a strange thing happens. When I go to 12.345.6.78:18845, for example, from my browser, it times out because apparently my browser puts a / at the end of the link, well when I go to the private IP, for example 192.168.2.8:18845, it loads the page just fine. Yes the device IP is correct, Ive re-done it 100 times, and the global port range is 18845, as so as the local base port, so it is not an incorrect port or IP. But when I connect to 12.345.6.78:18845 through insomnia as a GET request with no / at the end, it loads just fine until I put the / at the end. What’s going on here? Is there any setting that blocks certain clients or something?Yes I have seen this link and have tried these to no avail: Please help soon as I need to make this panel s

Are there any plans to release a new firmware for the sb8200 on Comcast to support mid split?

Hey so my modems Ethernet ports are not both active. I have 2 PCs plugged in and only one is registering a connection even they are both hardwired Ethernet into the same modem. I just got off the phone with Comcast and they said it was a manufacturing issue? Any help and support would be great. 

My family bought an Arris S33 Modem and it just keeps randomly resetting and I’m confused by it, we changed the power source to an outlet but it still resets, we keep it cooled as well but it still resets. I’m completely stumped on why it keeps resetting and I need help resolving this issue.

Nest WiFi + Arris S33 Modem + Xfinity.New modem replacing old arris. “Connection failed” during WiFi setup and prompt to connect Ethernet cable during setup. Modem delivering connectivity when hardwired to laptop.Thanks to Google community posts I have troubleshooted- power cycling both devices many MANY times + factory restoring- Reprovisioning modem (myself through Xfinity app and via cust service)-Opening bridge on modem (Arris said it’s not possible on a cable modem. Xfinity said they did it after saying they don’t deal with 3rd party modems but not sure they understood me or did anything)-Returning modem to best buy and replacing (same issue)-Giving my router MAC and serial to Xfinity to push the internet through (they were pretty clueless and ended up also taking my modem Mac and serial and probably using that instead)Everyone is blaming everyone else and no one will talk to the other providers so I am stuck. Google have

Trying to login to my Arris router model DG3450. It keeps saying invalid credentials. How to I reset it. 

Hello, how do I change the WiFi name for my DG3450?  

Top pick for Mediacom 1g connection. Currently have a Surfboard 8200 for 5 years but seemingly goes in and out to my router at least once per day. Looking to replace

I'm trying to find my IP address on my modem which is an SBG6580 modem.

Just bought a used SB8200 on eBay from a reputable seller.  I tried to provision it with my Wow ISP via a phone conversation.  The rep said that there is an error “equipment must be in a special status to add it”.  She said it was locked.  I did a factory reset.  Connected it directly to a laptop without internet and logged into the modem.  I was able to change the default password to a new one.  Tried to provision again by swapping it with my old SB6183 and calling the ISP.  Same error.  While trying to provision, I can access the modem web page through my router but the username and password doesn’t work.  As soon as I take it off the cable and router and connect to my laptop directly, the username and password I created works. When putting my system back to the SB6183, they had to re-provision it to make it work (proving they removed that modem while trying to provision the SB8200).We have verified the MAC address multiple times. Is there anything I can do on

Trying to determine if the refurbished modem I just bought from Amazon is the problem for extremely slow speeds or if the modem is bad. Following steps I found in FAQs, I got the attached results but I’m too confused to make sense of it.

How can I reset my modem SB8200? I moved from one address to another.

I upgraded to 1GB speed with Optimum. Will my current TN1602A be able to support the 1GB speed?

Hi, I can’t run wifi here and need wifi turned off. I was looking at the SBG8300 and see that wifi can be disabled. The description says that it includes a wifi router though. So, if I have wifi off, will it still support routing for wired ethernet devices like PCs?If so, how many wired devices can it support (I have a 12 port switch I will connect it to)? Thank you!

Hi i am looking for nvg653ux firmware beacuse my 5g cpe router not connecting properly to 5g network.. please help me out..

Xfinity called regarding Modem not having enough Fire Wall protection. What do I need to do?

So I’m trying to login to my DG3450. I got it from the cable company, who cannot help me at all with this. It asks for username and password, which should be “admin” and “password”. I tried it and get “Invalid Login Credentials.” I also tried using the password for my network. The cable company tech support person said that I had to use my network name for username and my network password for the password. Never heard of such a thing before, but tried it and it gave me “Operation Failed.” So I’m thinking that whoever had the unit before me changed the password. The cable company tech support said that I’d have to do a factory reset, even though I’ve done those before and it doesn’t actually reset all of the passwords and such. So I did it and, of course, it didn’t work. So how can I get access to my router if someone else changed the password and there’s no way of getting it from them?
