Dynamic Frequency Selection (DFS) is a protocol allowing routers and other wifi devices to connect over certain channels on the 5 GHz band that are normally reserved for weather radar and satellite communication. DFS allows an eero network to use higher performing wifi channels. The channels covered by DFS are typically much less congested than other 5 GHz channels which can result in less network congestion. Less congestion means better performance and reliability for your network.
While broadcasting on a covered wifi channel, eero uses DFS to continuously scan for radar signals (called "strikes"). If your network encounters a strike, it will automatically switch over to a non-DFS channel.
How do I enable DFS?
DFS is automatically enabled on eero networks running eeroOS v3.19 and higher. Your network will check channel conditions regularly and shift to the least congested channel when necessary.
Do I need to do anything on my devices to use DFS?
No, your devices will automatically use the channels set by eero.
