+ \\ Protected Management Frames (PMF) provide security for unicast and multicast management action frames. PMF prevents unicast management action frames from eavesdropping and forging. It also prevents forged multicast management action frames. PMF augments existing privacy protections for data frames with mechanisms that improve the resilience of mission-critical networks.
 By default, this feature is disabled because not all wireless clients support it.

+This specifies the time period between one beacon broadcast and the next. A beacon is a packet broadcast by the router to synchronize the wireless network and serve administrative functions. Beacons typically include information such as the SSID, Timestamp, various parameters and the router's available services.
+Beacons use up some network bandwidth that could be used for transmission of actual user data. Therefore, using a higher value (more time between beacon broadcasts) may achieve better throughput on your network.
+Using higher beacon values may also extend the battery life of some mobile client devices. This is because WiFi adapters are able to “sleep” in between beacon broadcasts. When beacons are less frequent, your devices have more time to sleep, saving energy in the process. Thus, battery life increases.
+Setting a lower beacon interval allows faster router discovery. When the router sends beacons more frequently, clients can discover it more quickly. This can help with weak signals and poor reception environments. After all, the more frequenlty beacons are sent, the better the chance client devices will receive them. This can also be helpful when you are using roaming features, with multiple APs. It allows the client devices to better choose which AP to connect to.

 Generally, the relationship between Wifi (clients) and a broadcaster is generally first-come first-serve. Moreover, many broadcasters might take the slowest client's speed as the effective rate of all connected clients on the same band.
-when Airtime Fairness is turned off -- the case of most broadcasters -- this is generally the norm:
-When an access point reaches its capacity in the amount of simultaneous active clients it can handle, a newly active client will need to wait its turn to transmit.
-Hundreds of clients can stay connected to a broadcaster, but only so many can be active simultaneously.
-This wait time depends on how slow the currently active ones are and how much data they need to transmit. But in any case, bad efficiency is inevitable when you have a lot of slow devices. That's because the access point will not do anything about a new (possibly much faster) client until it's done with one of those it has at hand.
-Again, that's first-come-first-served.
-Here's an analogy of first-come-first-served:
-You might have experienced long checkout lines in a big store like Costco -- a giant chain grocery store anyone with a family in the US would know. Everybody might have same-size shopping carts, but some are full of small items while others are half-full or even close to empty.
-If you have just one or two items in your cart, behind a person with a full cart, you'll have to wait for a long time before your turn. And when it's your turn, it takes you just a fraction of the time to pay and get out.
-If only you were allowed to cut in line.
-Airtime Fairness turned on: Equal air time
-With Airtime Fairness turned on, the access point now allots a dynamically determined equal amount of time for each client, regardless of how fast or slow they are.
-Airtime Fairness settings on an Asus router
-So, for example, if the equal amount of time is determined at 5 seconds, a slow client that needs 20 seconds to finish transmitting its data will have to pause after 5 seconds, and wait for the access point to deal with one or more clients, each for 5 seconds. And then it'll get back to its turn. So on and so forth.
-That said, with ATF turned on, fast clients get benefits at the expense of slower ones. How efficient this pans out depends on the situation: how many slow or fast devices are involved, how big the performance gaps between them are, and how much data each needs to transmit. It's super unpredictable.
-But as a whole, in terms of the total data being moved, this method is better than first-come-first-served when there are one or a few fast clients involved.
