Arris Nbn Modem Login

[Kerby Kolpack]

Hiall,

I just bought a new SB8200 from Amazon and performed a factory reset. When I access the modem remotely I'm not prompted for any login credentials and I see no options to add them. According to Arris I should be prompted for a username and password ( _FAQs/SB8200-Web-Manager-Access).

I think it is a little unsecure in that someone on your wifi can interupt service for a short perior by browsing to the modem's admin page and resetting the device. Other than that I don't see any security holes. You could block access to this IP using firewall rules on some routers, (this is straight forward to do on my pfSense router!).

I have experieced the same no login page as everyone else on my SB8200. But today I was trying to check my signal levels and am now hitting a login page. But nothing I have tried has worked. Arris says the default for this device is Username = "admin" Password = "password".

I have a Surfboard SB6190 cable modem and I cannot login to it. I type 192.168.100.1 into the address bar an hit enter. That brings up the Arris login page with boxes for username and password. I try my last known good username and password and get an error message: "invalid username or your access has been locked due to multiple failed login attempts". So I attempt to reset the modem to factory defaults by depressing and holding the button on the back of the modem for ten to fifteen seconds, unitl the lights on the front shut off, then I allow it to turn back on. At this point the username and password should be reset to the factory defaults of admnin and password, but still no dice. I've tried this several times and I always get the same error message. Does Comcast lock users out of their own modems? Did my modem just take a dump because they are cheaply made?

On some modems, there was a change in default passwords. Try using "admin" (must be lower case), and for the password, try the last 8 digits of the modem's serial number (should be on a tag somewhere on the modem.)

@andyrossI'll try that, but unless they changed somehow, the default username and password should still be admin and password, lowercase. I've been logged into the modem before, during initial setup and again anytime the internet was down. The modem is on another floor from my pc and that's how I usually restart it.

@jav6joev I finally got around to calling the 877 number and the agent recommended trying the last eight digits of the serial, after he told me my warranty was expired. I think the modem was just on it's way to catastrophic failure. Now when I try to login it does nothing or I get the spinning pinwheel. I had purchased a new SB6190 earlier this week and installed it then configured it with the Xfinity app no problems. Thank you for your help.

I had the same situation with my SB8200. Called Arris and after a lot of back and forth, the technician said tried admin./password, which did not work. Then, he said try admin/last 8-digit of S/N and it worked. Then, I reset the password.

Now, you need to log in to your Arris modem router to manage your network, change login details, create guest networks, view your SSID, and other settings. Also, while setting up your new network, you might need to log in and configure a few things.

To sum up, logging into your Arris modem router is very quick and simple. All you have to do is use the IP address to access the portal and enter your credentials. Once you are logged in, you will be able to manage your network, change the settings, reset your router, and do much more.

I am hoping somebody who reads this has cURL'd into an SB8200 cable modem (or similar) with user/pw authentication and can just post the details. More likely will be many suggestions of things to try and some google result links, most of which I likely tried already. What would be most helpful to start I think is troubleshooting why I cannot get a successful login and the credential cookie set on my initial cURL.

BTW - The username and password are known to me, were set by me, and work fine to login from a browser. I think no matter how I have passed in the credentials I am just being returned the login form again. Maybe basic auth will never work and I need to do something else.

EDIT: I discovered the "Preserve Log" option in Chrome dev tools. This allowed me to copy as curl both the login and the redirect actions. And running the login curl (which does use basic auth) does return me on stdout a credential cookie. I was not able to get this cookie stored in my cookies.txt file using the cookie options in curl. And immediately using the returned cookie in the redirect curl does not get me the expected results and instead returns the login page. But I am getting closer.

Solved it myself. Once I was able to save the login as curl in chrome, things fell in place. Looks like I was missing some required curl options in my initial attempts. I still need to skinny this down to the minimal necessary options, eliminate the double copy of user/pw chrome encoded, and add error checking. But the following will successfully login and pull modem status for an Arris SB8200. Never did get curl to store the credential cookie in a cookies.txt file so just used a local shell variable.

(Perhaps its app would have simplified the set-up. We shall never know. I actually installed it on my Teracube 2e, which is no longer my daily-driver phone. It wanted me to make an online account and I decided that I did not need an online account for my modem.)

I doubted that I would have much to do after signing into my modem. In order to access my modem directly, one would need to be connected to my internet But I still decided it would be best to change the default username and password. To be sure, it is possible that I could not do better than the super secure default admin/password username/password combination, but there is no harm in trying.

I fully expected to login to my modem with the modem-provided credentials. However, my hopes were dashed when the modem rejected my login. I tried once or twice more thinking there must be a mistake. But not only was I unable to log-in, the modem informed me that I would have to wait five minutes before making another attempt.

Once I was logged in, the modem prompted me to pick a new password. The new password had to be between 8-20 characters and have at least one upper case and lower case letter, one number, and one special character. Having learned my lesson about how passwords can be finicky, I opted to use diceware to generate a three-word password and then add one number and punctuation manually. It took two tries to get a password less than 20 characters. The modem accepted my password.

Sure enough, there was very little to do in the modem UI. There is a single toggle for enabling link aggregation set-up which I left off (I do not know the use-case as of the moment I am writing this). Having changed the password, I logged out of the modem.

If you use an Arris modem or router to connect to the internet, you may need to get into its configuration menu from time to time. You can usually do this with a username and password, and if you don't know the username and password, you can try the Arris default login settings. If you have trouble getting into your router, contact your internet service provider for help.

Arris makes a variety of modems and wireless routers that you can use to connect to your internet service provider. In some cases, you may own your Arris device, but it others, your internet service provider may rent the router to you.

Either way, if you have trouble with your device or need to change the wireless or other settings, you need to connect to the device. Typically, you can do this by accessing the device through your wireless or wired home network by connecting to its IP address, Simply enter that address into the address bar on your browser, whether on your computer, phone or tablet.

When you connect, you are usually prompted to enter a username and password. If you haven't changed your Arris modem login settings, try using the Arris default password and username. The default username is "admin," and the Arris default password is "password." After you connect, you can change a variety of settings depending on your Arris device model, often including passwords, wireless connection settings and other information. If you're not sure what value to use for any particular setting, contact your internet service provider for help or consult your device's manual.

If you are having trouble with your Arris router and can't find a proper setting to fix it, or you don't know the Arris modem login information for your device and think it may have been changed, reset the device to factory settings. You usually do this by pressing and holding the reset button on the back of the modem for about 15 seconds. This resets all the default settings, including passwords, which may solve your problem or make it easier for you to log in to the device.
