Although some Linksys routers require a default username, the E2500 does not, so you can just leave that blank. Like similar routers, 192.168.1.1 is the default IP address used to access the web interface.

When the E2500 Default Password Doesn’t Work

The default password and username for this router are always the same when the router is first installed, but you can (and should) change both to something unique and considerably more secure. The only downfall to that, of course, is that these new, more complicated, words and numbers are easier to forget than a blank username and admin. If you don’t know the login details you assigned to the router, you have to reset it to its factory settings. Resetting the E2500 is the only way to restore the default username and password. Here’s how: Now that the settings have been restored, you can access the Linksys E2500 at http://192.168.1.1 with admin for the password. Be sure to change the router’s password to something secure, as well as the username, if you want a bit of an extra layer of security. Now, you have to reconfigure your wireless network settings because resetting the E2500 removed all your custom ones. This includes your network name, network password, and any other custom settings you may have configured, like port forwarding rules or custom DNS servers.

When You Can’t Access Your E2500 Router

Most routers are accessed as a URL through their IP address, which, in the case of the E2500, is http://192.168.1.1 by default. However, if you’ve ever changed this address to something else, you need to know what that address is before you can log in. Finding the E2500 IP address is easy and doesn’t require a process as involved as resetting the whole router. You can do this if at least one computer that’s connected to the router is working normally. If so, you need to know the default gateway that the computer is using.
