Hard reset instructions for Arris SB8200

If your SB8200 router is not working as it should, dropping connections or not being responsive, you should first do a reset of the router to see if the problems persist. Other scenarios where you might want to reset your router is if you've forgotten the password or misconfigured it and can't get access anymore.
Your can reset your Arris SB8200 in the following way(s):

The 30-30-30 reset

There are no specific instructions for this model yet, but you can always do the 30-30-30 reset as follows:

When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
While still holding the reset button down, turn on the power to the unit again and hold for another 30 seconds.

This process usually works for resetting any router to it's factory setting. If that doesn't work be sure to check out the questions and answers incase someone else has had similar problems resetting their router.

Note: It is worth reading more about how to reset routers with the 30 30 30 reset and what the risks and considerations are when resetting your router this way, instead of just rebooting it.

Default factory settings for Arris SB8200

If you have performed a reset of your SB8200 device or not changed the defaults, you should be able to access it with the following settings:

Default Gateway IP: 192.168.100.1 Arris login instructions
Default username: admin Arris router default password list
Default password: password
Default subnet mask: 255.255.255.0
Default DNS server: 192.168.100.1
Note: If you are using the default settings you should change them to increase security and prevent unathorized access to your network.

To login to the SURFboard DOCSIS 3.1 Cable Modem and change the settings, you can follow these steps:

Make sure you are connected to the router's network, either by Wi-Fi or ethernet cable.
Open your browser and visit http://192.168.100.1
You should be prompted with a login dialogue.
Enter the username: admin and the password password
Note: If you have already changed the password use that instead.
You will now be logged in. If you haven't yet changed the defaul password, we recommend that you change it first thing you do after logging in.

If these instructions don't work for your router, you can always try a factory reset to get the default, or try some other common Arris credentials, as they can usually be shared across models/variants.
