3Com Router Login
What to do if your router stops working after changing configuration
Follow these instructions to login to your 3Com Router.
1. 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 3Com router. This avoids the risk of suddenly being logged off when saving your changes.
2. Open your web browser of choice and type IP address of your 3Com router in the address bar. You can find the ip address on the back of your router.
3. 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 3Com routers.
