When you power on the WatchGuard AP, it automatically scans the network and selects the wireless channel with the least amount of interference. The WatchGuard AP is configured by default to select a wireless channel automatically. Using DFS channels can be helpful with 802.11ac and an 80MHz channel width because of the extra spectrum availability, but using these channels can result in your APs being slow to connect on the wireless network. Because DFS channels are used with radar, transmissions from your AP stop if radar signals are detected on that channel. In some regions, DFS (Dynamic Frequency Selection) channels operate in the 5GHz band.

The full channel width is reserved and there is a very large selection of channels that do not overlap. In the 5GHz band, there are many possible channels. When you deploy your APs, use different channels for each AP and place them so that different channels are used in locations that do not overlap. The 2.4GHz band is crowded because many other devices that operate on this band (such as cordless phones, microwaves, monitors, and wireless headsets) also use the same channels, and can cause wireless congestion. They do not overlap each other because of the space between their frequencies. In the 2.4 GHz band, channels 1, 6, and 11 are the most commonly used channels.
For example, in the 2.4 GHz band, adjacent channels such as channel 3 and 4 have frequencies that closely overlap, which can cause interference. When you design and deploy wireless networks, you must consider which channels you use for your wireless network. One wireless channel can overlap the frequency of another wireless channel. Channel 14 is for Japan only and is spaced at 12 MHz. Channels 12 and 13 are available in countries outside of North America. In the 2.4GHz band with a channel width of 20MHz, there are 14 defined channels spaced every 5MHz. ChannelsĪ wireless channel is a specific division of frequencies in a specific wireless band. Physical obstructions and wireless interference reduce your effective wireless range and data speeds. The 5GHz band is less congested and provides faster data rates than 2.4GHz, but it also has less range than 2.4GHz. The slower devices often use more of the available throughput because it can take much longer to send or receive the same amount of data to those devices. This is in part because of backward compatibility requirements when devices that use slower modes are connected. If you choose a wireless mode that supports more than one 802.11 standard, the overall performance can be impacted. Because of this, we recommend that you configure your WatchGuard AP to use mixed protocol modes.
