The Linksys E1200 default password is admin. As with other passwords, the password for the E1200 router is case sensitive, which in this scenario means uppercase letters cannot be used. When you're asked for the default username, enter admin also. A common default IP address for Linksys routers is 192.168.1.1, and it's also the default IP address for the Linksys E1200.Linksys
There are three hardware versions of the E1200 router (1.0, 2.0, and 2.2). Each version uses the same username and password (which is admin for both).
What to Do if the Linksys (Cisco) E1200 Default Password Doesn't Work
If the default password of admin doesn't work for your E1200 router, it means that it's been changed to something else. When you don't know the password and have no way to find out what the password is, reset the router to its factory default settings, which will restore the default username and password.
To reset the Linksys E1200 router:
Plug in and power on the router.
Flip the router over so you have access to the bottom.
With a small and sharp object such as a paperclip or pin, press and hold the Reset button for 5 to 10 seconds.
Flip the router back over to its normal position, then wait 30 seconds for the Linksys E1200 to fully reset.
Unplug the power cable for a few seconds and plug it back in.
Wait 30 seconds or so for the Linksys E1200 to power on.
When the router has reset, log in with the default username and password of admin. Use http://192.168.1.1 to access the router.
Change the router password to something that's more difficult to guess than the easy-to-guess password of admin. Store the password in a free password manager to make it easy to remember.
Resetting a router means that all the settings are deleted and restored to the original factory defaults, this is how the router was set up right out of the box. After a router has been reset, enter the customizations you made prior to the reset such as wireless network settings (for example, the SSID and wireless password), DNS server settings, and port forwarding options.
To avoid having to enter the information for the router customizations after a reset, back up the router configuration to a file.
Help! I Can't Access My E1200 Router
The default IP address for the Linksys E1200 router makes the URL for accessing the router http://192.168.1.1. However, if you can't reach the router with that address, it means it's been changed to something else.
Unlike having to reset the router to get the default password restored, you can see what the default gateway is configured as on a computer connected to the router. That IP address is the same as the router's IP address.
