Problem

If you have two competing SSIDs (Networks/WiFi names) added to your system you may experience disconnections when doing things like video chats or things were movement from one SSID to the other is apparent.

Example Scenario

For example:

Say your a teacher at a local school district and you are connected to both a public network, like SD-Public as well as a private network like SD-Private. When you are roaming about your school or classroom you notice that your connection (WiFi) seems to drop and the performance seems poor. The reason for this is your machine is constantly trying to connect to the strongest signal, which changes from SD-Private and SD-Public as you roam about. The end result is that your computer constantly disconnects from one access point to the other, creating the appearance of dropped network connections and poor performance. This problem is amplified if one of the networks you are trying to connect to has MAC filtering in place.

MAC Filtering: Allows an admin to allow or deny a wireless or physical connection to a network based on your systems hardware MAC address (unique to every device).

But My Computer Only Sits In One Place: This can occur even if your computer is sitting in the same position and hasn’t moved. People moving about the building or physical obstructions will absorb or attenuate the signal and affect the wireless signal strength.

Solution

The solution to this is to use ONLY a single SSID or WiFi Network. For instance if you are only allowed to use SD-Public, only have SD-Public added to your saved WiFi networks. If you know your device has been added to a MAC allow list of a private network, like SD-Private then only connect to SD-Private.

Providing an exhaustive list of all devices you may have as well as their operating system would be a daunting task.

My suggestion is for you to perform a Google search:

There’s a wealth of guides on the internet and a solution is likely within the first 5 links returned by Google.

If all else fails contact your tech for assistance. There may be other issues but if your working in an enterprise environment with multiple SSIDs (Private and Public) this issue occurs fairly frequently.

Best of luck 😎
