The Link creates two separate Wi-Fi networks -- a 2.4 GHz network and a 5 GHz network -- as described in the Quick Start Guide in this article.
The default setting on the Link automatically chooses a channel for each Wi-Fi network.
The channel currently used by each Wi-Fi radio is shown when first logging in to the Link's Web UI under the Status > Wireless section.
If other devices such as Teradek Bolts are already operating on that channel, or if you are trying to manually specify channels used on the Link to coordinate with other transmitters and minimize interference, you can adjust the channel used for each Wi-Fi radio.
1. Log in to the Link's Web UI as described in this article.
2. Select Network, then Wireless.
3. Options for both the 2.4 GHz and 5 GHz Wi-Fi networks are shown; click the Configure button specific to 2.4 or 5 GHz network that you wish to change. Alternatively, you can click the Disable button to completely turn off a specific Wi-Fi radio on the Link.
4. Under the Device Configuration section, select General Setup.
5. In the Channel drop-down list, choose auto (to allow the Link to automatically choose a channel in the 2.4 or 5 GHz range) or manually select an individual channel to force the Link to use only that specific channel.
NOTE: when manually selecting a channel for a radio, ensure that the channel selected is compatible with all devices that you wish to connect to that 2.4 or 5 GHz Wi-Fi radio on the Link.
6. Click the Save button if you are adjusting other settings on the Link and will apply the changes later, or the Save & Apply button to have the new Wi-Fi network name take effect immediately.
