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.
