Linksys MAX-STREAM EA8100 Mode D'emploi page 14

Wi-Fi Settings
Lets you configure your router's wireless network. You can change the security mode, password,
MAC filtering, and connect devices using Wi-Fi Protected Setup™.
DFS
If your EA8100 can use Dynamic Frequency Selection on the 5 GHz band, DFS uses 5 GHz channels
that are shared with radar systems. When a radar is detected on your operating channel, the router
will search for an unoccupied DFS channel. During this time, you may lose Wi-Fi connectivity. This is
more likely to happen if you live within 20 miles (35 kms) of an airport. Another limitation is that some
devices do not support DFS channels and can only use your 2.4GHz network when the router is using
a DFS channel.
