Manual Channel Selection and Transmit Power Adjustment

The ability to manually set the Radio Channel and Transmit Power on MR Access Points, MX64/65W Security Appliance and Z1 Teleworker Gateway gives you more granular control over the wireless coverage in your environment. You can successfully make these adjustments in the Cisco Meraki Dashboard by following the steps below: 

MR Access Points

  1. Log in to Dashboard.
  2. Navigate to Wireless > Configure > Radio settings.
  3. Using either the Map or List view, click on the AP you would like to adjust:
  4. In the section that appears to the right, use the Channel field to adjust the channel the indicated radio will operate on, and Power to indicate what power level to use:
  5. Click Save changes
  6. Clients will be disconnected briefly when you change channels or power levels

Note: The 2.4GHz radio on an MR access point can have its power set to "off." This will prevent this particular unit from serving clients with its 2.4GHz radio.

MX60/64W and Z1

  1. Log in to Dashboard
  2. Navigate to Security appliance > Configure > Wireless settings
  3. Under Channel Settings, use the Channel field to adjust the channel the indicated radio will operate on, and Transmit power to indicate what power level to use.
    Note: The screenshot below shows configuration options for an MX64W or Z1, which both support simultaneous communication on both the 2.4 and 5GHz bands. The MX60W can only communicate on one band at a time.
  4. Click the Save changes button.

  5. Clients will be disconnected briefly when you change channels or power levels.

Best Practices

Manually setting the channel can improve roaming performance for clients who cannot seamlessly roam between APs on different channels. However, manual channel selection can also increase the amount of co-channel interference produced by nearby APs if using the same channel. Co-channel interference can also be improved by reducing the Transmit Power on nearby APs. When unsure if manual settings are needed, leave channel and power settings on Auto.
