Cisco's defaults depend on the type of device. Small business routers use cisco / cisco. Cable gateways often have a blank username and password. Home routers use admin / admin.
The Most Common Cisco Logins
- cisco / cisco: small business RV and CVR routers.
- blank / blank: many DPC and EPC cable gateways.
- admin / admin: Linksys-era home routers and some cable gateways.
- admin / password: Xfinity versions.

If the Default Password Doesn't Work
Try each default for your type of device, then ask your ISP if the gateway came from them. If you're still locked out, reset the router.
To change the password, go to Administration > Users (small business) or Administration > Management (gateways and home routers). See choosing a strong password.
