If you are unable to login to your 3Com Wireless gear, it may be because you are typing-in incorrect authentication (username/password) details. Double-check your password (if any), and verify that neither the CAPSLOCK key on your keyboard is “On,” nor one of the SHIFT keys on your keyboard stuck in pressed-down state.

Considering that many administrators restrict how (using only wired, terminal, or wireless access), and from where (using filters based on IP addresses, MAC Addresses, or only from select computers) various devices can be configured, it may be quite possible that you are not even reaching the device in question. It may be helpful, therefore, to try to login using a wired (LAN based, or Terminal/Serial Port) access before doing a brute-force factory reset on your 3Com gear.

Just like all other 3Com Wireless Access Points, your 3Com AP has been factory configured to use a rather well-known factory default username and password combination.

Your 3Com Access Point –as it is delivered to you –may be setup to require either no (a blank) password at all, or to use something as obvious as admin, password, or comcomcom for full administrator access passcode.

You should, therefore, change your password as soon you have powered up your 3Com Access Point for the first time, or every time you have to reset it to its factory default settings.

As may be evident from the following, what 3Com uses as factory defaults (for Username, Passwords, Access method, Default IP address, and Netmask, etc.) for various 3Com APs is highly predictable:
