Troubleshooting
2. Use a tip of a pen to press the Reset button while reconnecting the
power cable. Keep the Reset button pressed for at least 20 seconds.
3. The Ericsson W21 restarts and comes online with the factory default
settings.
Note: A reset to factory default configuration cannot be undone. If you
reset the Ericsson W21 to default configuration, all your previous
configuration changes are replaced. If you have previously
changed the user name and password, the User Login page will
be displayed. You have to login to the web pages with the default
user name and password (user in both fields).
4.3 No Access to Ericsson W21 Web Pages
If you cannot access the Ericsson W21 internal web pages, take the
following actions to identify and solve the problem:
• Check that the PC is configured to obtain an IP address automatically
using DHCP. If not, change the PC’s TCP/IP settings. For instructions,
see section 3.1.1 – Obtain IP Settings Automatically or the manual of
your operating system.
• If the Ericsson W21 IP address has been changed and you do not
know the current IP address, use the Reset button to reset the
Ericsson W21 to factory default configuration (see section 4.2). This
will set the IP address to 192.168.1.1 and the web page address to
http://192.168.1.1.
• Make sure you are using the correct login details. If the default
password has been changed and you do not know the current
password, use the Reset button to reset the Ericsson W21 to factory
default configuration (see section 4.2). This will reset the login details
to default values. The default user name and password are “user”.
• If the PC is connected to the Ericsson W21 via an Ethernet cable,
check that at least one of the corresponding LAN connector indicators
is lit. If not, make sure that the cable is properly connected or try with
another Ethernet cable.
• If you are using a wireless PC, make sure that the Wireless LAN
indicator on the front panel of the Ericsson W21 unit is lit. If not,
connect an Ethernet cable between the PC and the Ericsson W21 to
establish a connection. The wired connection is required for the initial
Wireless LAN configuration of the Ericsson W21.
