Dynamic Frequency Selection (DFS) allows Linksys devices to operate in channels shared with radar that are typically much less congested than other 5 GHz channels. Reduced congestion means better performance and reliability for your network. Some Linksys Velop Mesh models use DFS to optimize your WiFi. 

Do all Linksys routers support DFS?

Not every Linksys router is equipped with DFS support. If your router does support DFS, you will be able to identify it in the Linksys app or LinksysSmartWiFi.com page.

Do I need to do anything on my client devices to use DFS?

Some devices don't support DFS channels. They will need to use your 2.4 GHz radio instead of the 5 GHz radio. Make sure your devices support DFS and have the latest updates.
 

When do I need to disable DFS?

While enabling DFS can be advantageous, the following are circumstances in which it becomes necessary to deactivate DFS on your network:

• If you encounter problems with adding a child node or connecting to it after turning ON DFS, it could mean that the child node doesn't support DFS.
• Client devices that lack support for DFS on dual-band networks may end up connecting to the 2.4 GHz radio instead of the 5 GHz radio.
• If the router detects radar systems that use the same DFS channels, the router needs to disconnect and switch to a different DFS channel to avoid interference. If you experience frequent disconnections because of the proximity of radar systems, you can turn OFF the DFS feature.
