FAQ — 3Com router login

What is the default IP address of 3Com routers?
3Com routers most commonly use 192.168.1.1 as the default gateway, though some models ship with 192.168.0.1 or another address. The full list is on this page.
What is the default username and password for 3Com routers?
The factory default is almost always admin / admin or admin / password. Some newer 3Com models leave the password blank or print a unique value on the sticker.
How do I reset a 3Com 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 3Com router?
Log into the admin page, go to Administration → Firmware Upgrade (the exact menu varies by model). Modern 3Com routers can check for updates online; older ones require downloading the firmware file from the official 3Com support site and uploading it manually.
Why is my 3Com 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 3Com mobile app instead of the web interface?
Yes — most modern 3Com 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.
