Login addresses, default credentials, and setup instructions for 3Com equipment.
A shared web login address is not listed for this equipment. Check the model instructions below for app access, the device label, or your router’s gateway address.
Connect to the router’s Wi-Fi or Ethernet first. These links open a new tab on your device; the address may differ if the network was reconfigured.
QUICK START
Most likely login options
Start with the option that matches your model. Defaults apply to the factory state; use the password you chose if the device has already been set up.
Options are ordered by manufacturer documentation and coverage among the listed models. Hardware, firmware, and ISP versions can differ.

GET CONNECTED
How to reach your router
- Connect your computer or phone to the router’s Wi-Fi or an Ethernet port.
- Open a documented login address. If it does not load, look for the Router or Default gateway address in your device’s network settings.
- Match your model and hardware revision to the table. Use the device label or your setup password when the model has no shared default.
Admin password or Wi-Fi password?
The admin password opens the router’s settings. The Wi-Fi password connects a device to the wireless network. They may be different, and an ISP or cloud account can be separate again.
If the password does not work
Check capitalization and the device label, then use the manufacturer’s password-recovery instructions. A factory reset erases settings and may require ISP setup details; follow the instructions for your exact model.
