Follow these instructions to login to your
WRT1200AC v1 Router.
Connect router cable to your Laptop or Computer. Alternatively use your wireless network.
Recommendation - It's best to use a wired connection while setting up the WRT1200AC v1 router. This avoids the risk of suddenly being logged off when saving your changes.
Open your web browser of choice and type IP address of your WRT1200AC v1 router in the address bar. You can find the ip address on the back of your router.
Now enter the default username and password of your router by accessing the admin panel. If you don't have your username and password, you can try one of the default passwords for WRT1200AC v1 routers.
If you can’t log in to your router, then you are probably entering the wrong username or password. Remember to make a note of both after you've changed them.
