the wireless client are the same.
Note that the network name is
case- sensitive.
Verify that the operating system
and Wireless LAN interface of the
client supports the authentication
and encryption method (WEP 64-
bit, WEP 128-bit, WPA, or WPA2)
configured on the Ericsson W21.
These settings are displayed on the
Wireless LAN web page. If the
security method is not supported,
configure the Ericsson W21 to use
another method.
For the configured security method,
make sure that the same
encryption key or passphrase is
configured on both the Ericsson
W21 and the client device. Note
that a passphrase is case sensitive.
If whitelist is enabled, verify that the
wireless client is included on this
list.
If the wireless client uses a static IP
address, make sure that this IP
address is on the same subnet as
the Ericsson W21. For instructions
on how to check the client’s IP
address, see the operating system
documentation or online help. The
Ericsson W21 IP address and
subnet mask is displayed on the
LAN page.
The wireless connections to the
local network are unacceptable
slow or regularly dropping.
Move the Ericsson W21 to another
location. Make sure that the mobile
network signal is still acceptable
before finalizing the installation.
Keep the Ericsson W21 away from
electrical devices that disturb the
radio frequency signals, for
example microwave ovens.
Make sure that your Ericsson W21
