Make your Wifi signal more stable

As Wifi gets used more and more chances are that your signal is being pushed away by other networks or that your house/location just won’t work well for Wifi. This can be caused by a million different things varying from a Dect Telephone to a Military Radar nearby. A concrete wall between you and your basestation or simply an active microwave.

To enlarge the changes your Mac will connect to your network you could lower the doorstep for it by lowering the Multicast Rate.

Usually this is set pretty low, say 5mbit, but that means that when your signal dips below that your connection is often lost.
Thus changing the setting to 2 or even 1.5mbit could enhance your Wifi experience. Keep in mind that this will NOT upgrade your signals quality, if anything the signal is less. All this setting does is lower the bar for when the signal is good enough for a computer to connect.

You can change this setting in Airport Utility by opening it up. Double clicking your Basestation in the left column and accessing the Wireless tab under Airport. Then click Wireless Options and set the Multicase rate to 2mbit or something in that area. As seen in the Orange oval.

Additionally you could experiment with the “Interference Robustness” setting. This COULD help boost your signal a bit. However, for me this caused the network to only slow down dramatically!
