The default IP address for the E1000 router is 192.168.1.1. This is what's entered as the URL to access the router settings. There isn't a default username, so leave that text field blank when logging in. However, there is a default password of admin, and, as with most passwords, the E1000's is case sensitive.
There are multiple hardware versions of the E1000 router and all of them use the same login information from above.
If the Linksys (Cisco) E1000 Default Username or Password Doesn't Work
The default username and password mentioned above is valid for the Linksys E1000 only if these credentials haven't been changed. If they don't work, it means that the default username or password was changed to something more secure. There's an easy way to reset your Linksys E1000 router back to its default settings, which will restore the default username and password, too.
Turn the device around so you can see the cables plugged into the back.
Press and hold the Reset button for 10 to 15 seconds. You may have to use a small pointed object (like an extended paperclip) to reach the button.
Remove the power cable from the back for a few seconds, and then plug it back in.
Wait for 30 to 60 seconds while the router starts up.
Make sure the network cable is plugged into the back of the router.
Reconnect to the router. Open a web browser, and in the address bar, enter http://192.168.1.1 (the default IP address). Then, when prompted, leave the username field blank and enter admin in the password field.
Change the default admin password to something more secure and consider storing it in a free password manager.
See How to Change a Router Password if you're not sure how to change the admin password.
When the default E1000 settings are restored, network and wireless settings are removed. To restore these settings, manually configure the network name, the network password, and any custom routing.
To avoid having to fill in all the custom router settings again if you ever have to reset the router in the future, back up all the router settings to a file. Go to Administration > Management, then select Backup Configurations. To restore the backup file, select Restore Configurations.
What to Do If You Can't Access the Linksys E1000 Address
The default IP address for the Linksys E1000 router is 192.168.1.1. This is needed to access the router. If it doesn't work, it may have been changed at some point through the router settings.
If the devices connected to your E1000 router are working just fine, but you don't know the IP address used by the router, find it in Windows by seeing which IP address is configured as the default gateway.
