FAQ — Castlenet router login

What is the default IP address of Castlenet routers?
Castlenet routers most commonly use 192.168.0.1 as the default gateway, though some models ship with 192.168.1.250 or another address. The full list is on this page.
What is the default username and password for Castlenet routers?
The factory default is almost always admin / admin or admin / password. Some newer Castlenet models leave the password blank or print a unique value on the sticker.
How do I reset a Castlenet router to factory defaults?
Find the recessed reset button on the back of the router. With the router powered on, press and hold it with a paperclip for 10–30 seconds until the LEDs blink, then release. The router will reboot with the original credentials and IP.
How do I update the firmware on a Castlenet router?
Log into the admin page, go to Administration → Firmware Upgrade (the exact menu varies by model). Modern Castlenet routers can check for updates online; older ones require downloading the firmware file from the official Castlenet support site and uploading it manually.
Why is my Castlenet router login page not opening?
Make sure you're connected to the router (Wi-Fi or cable), you're using http:// not https://, and you're entering the gateway IP from the list on this page. Run our reachability test to confirm the router is responding.
Can I use the Castlenet mobile app instead of the web interface?
Yes — most modern Castlenet routers support a companion app (e.g. Tether, Nighthawk, Smart Home Manager, Linksys app) that mirrors the web admin. The app uses the same login credentials as the web page at the router IP.
