a packet. This mode can minimize collisions among hidden stations.
- Click Disabled if you want to permanently disable this feature.
• Power Output: You can adjust the output power of the access point to get
the appropriate coverage for your wireless network. Choose the level you
need for your environment. If you are not sure of which setting to select, then
