Real answers to the questions people ask most about 192.168.100.1.

How do I login to my 192.168.100.1 router?
Connect your phone or laptop to the router (Wi-Fi or Ethernet), open any web browser, type http://192.168.100.1 in the address bar and press Enter. When prompted, enter the username admin and the password password. If that combination doesn't work, try one of the alternatives further down on this page or check the sticker on the back of your router.

How do I access 192.168.100.1 from Google Chrome?
Open Chrome and type http://192.168.100.1/ directly in the address bar (not the Google search box). Chrome may warn you that the connection is not private — this is normal for local router pages because they don't have public SSL certificates. Click Advanced, then Proceed to 192.168.100.1 (unsafe) to reach the admin page.
Is 192.168.100.1 a public or private IP address?
192.168.100.1 is a private IP address (RFC 1918). It only exists inside your local network and is not routable on the public Internet. Many millions of home routers worldwide use the exact same address — that's why it works for everyone.
Why is 192.168.100.1 not working / not loading?
Three usual culprits: (1) your device isn't actually on the network whose gateway is 192.168.100.1 — run the reachability test at the top of this page to confirm; (2) you're typing https:// instead of http:// and the router doesn't have an SSL certificate; (3) another device on the LAN has taken the IP. Reboot the router, plug in via Ethernet, and try again.
How can I change the username and password at 192.168.100.1?
After logging in to 192.168.100.1 with admin / password, look for a menu called Administration, System, Management or Tools. There you'll find a Change password option. Set a strong, unique password (at least 14 characters — our password generator can help) and write it down somewhere safe.
How do I change my Wi-Fi password from 192.168.100.1?
The Wi-Fi password (WPA key) is different from the admin password of the router. Log into 192.168.100.1, then go to Wireless, Wi-Fi or WLAN settings. Look for the field labelled WPA pre-shared key, Network key or simply Password. Change it, save, and reconnect all your devices. See our full guide.
I forgot the password to 192.168.100.1 — what can I do?
Locate the small recessed Reset button on the back of the router. With the router powered on, press and hold it with a paperclip for 10 to 30 seconds until the lights flicker. This restores the factory defaults, so you can log in again with admin / password. Be aware: this also wipes your Wi-Fi name, Wi-Fi password, and any custom configuration.
