How can I get my Arris router default username and default password?

The default user name is "admin". The default password is "password", in lower case letters

Usually arise provides password on the bottom of modem.

Even though it's an Arris, try this:
1. Open a browser window.
2. Type in the IP address for the modem 192.168.0.1.
3. Type in the default Username; admin.
4. Type in the default Password; motorola.

If that doesn't work, try "root" for the username and "motorola" for the password and reset it to factory settings. Then start again with the steps above and change the username and password to whatever you choose. Good luck!

Reset your router back to it's factory settings by holding the reset button for about 5 seconds. I have provided a list of the most popular router brands. If it does not work you may need to google what your specific model's default IP address/default username/default passwords are, for example search for "Encore ENHWI-2AN3 default IP address" The default login info can change, it can depend on where you obtained your router. If you purchased it yourself from a store then the standard defaults should work. If you obtained your router from your Internet Provider you may need to contact your service provider. It also may depend whether it's an old or new model router as well. And you may need to press and hold the reset button on your router several times before it actually clears. Make sure you have a wired connection then once you have accessed your router simply run the Setup Wizard. Set your SSID as something you'll remember like "Mavericks Network" and your Password can be something like your phone number for example 3109876543

The default username and password for most routers I have seen is admin and admin provided you have not changed it. All are lowercase letters.Also I suggest you use the WPA or WPA2+ encryption if its available. The WEP is easy to crack wirelessly and I had a gala time cracking my neighbor's router in less than 3 hours!

For the motorola router's default username is "admin"; The router's default default password is "motorola".

If it is a Motorola-Cablerouter then default username is " cablecom"; The default password is "router".

Reset the router to Factory Defaults if the password is not working and re-configure it .

You have to set seting from routers menu. To use it hold 15 second router restart button, that restore factory setings, then go browser http://192.168.1.1/ , and use username "admin" and password "admin" in default. There you can set setting by your connection.
