My other 4 laptops do not show any issues.Ī DTIM of 1 ended up fixing that issue. My surface book 4's connection goes into the weeds, with a DTIM value of 3, when I'm connected to a remote VPN The device goes into power savings mode requiring me to manually turn off-on the wireless to reconnect to the VPN. A couple Apple devices have a connection issue with this DTIM value and require a lower DTIM to operate reliably. This value fights with some Apple and android devices due to the aggressive power management strategy apple users on their devices.Ī DTIM of 3 will lower battery power consumption, slightly increase the latency seen while in those deeper sleep states and is the standard value on ASUS and current Apple APs. Values of 1,3 or 5 are possible.Ī DTIM of 1 prevents mobile device's radios from going into deep sleep, and thus consumes slightly more power on your battery powered devices. Depending on what version was your first installation is what DTIM value you ended up with. Ubiquiti has been playing with this value for the past year. Got mobile wireless devices that disconnect randomly? Or just want to check compare your settings?Ĭertain Apple devices and old Android phones work better with DTIM value of 1, and other (more recent) apple devices prefer a value of 3 That is how Ubiquiti suggests you configure the AP in an enterprise deployment. There are enterprise switches which include LAN to Port # Multicast filtering as a filter option for each port. NOTE: This setting is enabled by default to ensure that UNIFI APs are deployed in the most compatible configuration possible. This change results in a substantial increase in overall operational wireless performance:Ģ.) Left Side Bottom of the screen settingsģ.) Under Setting Choose Wireless Networksĥ.) Check the box for Block LAN to WLAN MulticastĦ.) If a server that provides multicast streaming on your local network stops working, add that Server's MAC to the exemption list.ħ.) Enjoy the huge up tick in performance and decrease in latency. Older versions can be modified via the configuration file. These changes require UNIFI Controller 5.5.x or greater if you want to perform them via GUI.
