Step 3 Enter the username and password and press Enter. The controller’s summary page appears.
Note The username and password are case-sensitive.
Step 4 Click Wireless > 802.11a Radios or 802.11b/g Radios and a list of associated access points displays.
Step 5 Choose the desired access point from the displayed list and click Configure. The radio settings page
displays.
Step 6 Scroll down to the Tx Power Level Assignment field, and click Custom.
Custom indicates that the radio output power is manually controlled by the Tx Power Configuration
setting field.
Step 7 In the Tx Power Level field, select the appropriate power level setting (1 to 8).
Based on the operating channel, the regulatory domain, and the controller power level setting (1 to 8),
the actual transmit power at the access point can be reduced to comply with special regulatory or country
restrictions.
Table 3-5 lists the controller power settings and the corresponding output power levels for these two
examples:
• 2.4 GHz (802.11b/g) operation:
– American regulatory domain and channel 2 using 11 Mbps data rates
• 5 GHz (802.11a) operation:
– American regulatory domain and channel 149 using 36 Mbps data rates
Step 8 Click Apply.

the access point. Each subsequent controller power level (such as 2, 3, 4, etc) represents
approximately a 3-dBm reduction in transmit power from the previous power level.
