7. Ensure that the channel has been changed by typing

show wlan

stat

command.

You have now changed the WLAN channel of your Nokia MW1122
and you can use the wireless LAN normally. You may need to restart
your wireless LAN clients if they do not support automatic channel
scanning. Consult the user manuals of each WLAN client for
instructions on changing their WLAN channels.

Controlling the access to your network

You can control the access to your MW1122 with an access list. By
default, this feature is off in MW1122. This means that all WLAN
clients are allowed to have access to your Nokia MW1122. Therefore it
is important that you identify your WLAN clients, add them on the
access list and activate the admission control function which prohibits
other WLAN clinets from entering your network. This is a major
security issue protecting your wireless network from outsiders. To add
clients to the access list:

1. Consult your computer’s and WLAN clients’ manuals on how to

find out your WLAN clients’ MAC addresses. For clients running
Windows 95 and 98 operating systems, you can find out the MAC
addresses by running

winipcfg.exe

and selecting WLAN card

from the menu. The MAC address is shown in the

Adapter

address

field.

2. Open a telnet or CLI session to MW1122 as described earlier in

this chapter.

3. Start the configuration mode by typing

configure

ENTER

4. Go to wlan configuration level by typing

wlan

ENTER

5. Add an entry on the access list by giving the following command:

sta–address xx:xx:xx:xx:xx:xx

, where

entry–name identifies the access list entry (for example, a PC host
name) and xx:xx:xx:xx:xx:xx is the MAC address of the allowed
wireless client.

6. Repeat the

sta-address

command if you want to add more

clients on the access list.

7. If you want to remove WLAN clients from the access list, just type

no sta-address xx:xx:xx:xx:xx:xx

, where

xx:xx:xx:xx:xx:xx is the MAC address of the wireless station you
want to remove from the list.
