3Com made the OfficeConnect routers and ADSL modem routers (3CRWER, 3CRWDR, 3CRWE and 3CP series) for homes and small offices. HP bought 3Com in 2010, and these routers are no longer made or updated.

Default 3Com Login Details
Most 3Com routers are at http://192.168.1.1. The most common login is blank / admin. Other models use admin / 1234. See the 3Com passwords and 3Com IP address pages.
OfficeConnect routers have a menu down the left: Welcome, Wizard, LAN Settings, Internet Settings, Wireless Settings, Firewall, Support/Feedback and System Tools.
Note: these 3Com models no longer get firmware updates. Set a strong admin password, use WPA2 WiFi, and think about replacing very old units.
