For all versions of the Linksys E2500 N600 router, the default password is admin. As with most passwords, the E2500 router default password is case sensitive.
Although some Linksys routers don't require a default username, the Linksys E2500 router does: It does not use a username. However, the default password is admin. That's right. It username is blank by default.
Like other Linksys routers, 192.168.1.1 is the default IP address used to access the router.
There are three different hardware versions for the Linksys E2500, but they all use the same username, password, and IP address.Linksys
When the E2500 Default Password Doesn't Work
The Linksys E2500 default password and username 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 username and password you assigned to the router, you have to reset it to its factory settings.
Resetting the E2500 to its factory default settings is the only way to restore the default username and password. Here's how:
Make sure the router is plugged in and powered on.
Physically turn the E2500 over so you have full access to the bottom side.
Using a small, sharp object such as a straightened paperclip, press and hold the Reset button for 10 seconds. Continue to press the Reset button until the Ethernet port lights on the back flash at the same time.
Unplug the power cable for 10 to 15 seconds and then plug it back in.
Wait 30 seconds before continuing so that the E2500 has plenty of time to boot back up.
Confirm that the network cable is still attached to the computer and router.
Now that the settings have been restored, you can access the Linksys E2500 at http://192.168.1.1 with the default login information of no username and admin for both 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. It might be a good idea to store the new password in a free password manager so that you don't ever forget it again.
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 Linksys E2500 IP address is easy and doesn't require a process as involved as resetting the whole router. You can find the router's IP address 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.
