Thanks for the replies. I'm not currently experiencing any Wi-Fi difficulty. I use a dual band WAP that I get up high for good LOS and don't broadcast SSID. Not looking to solve any problems. Just looking for information that may come in handy if a problem arises.
I always have a wired laptop for backup.
Scott, do you have a particular WAP you like? I use an ASUS AC1900. It would be nice to have something rack mounted with external antennae, or a small AP that I could get up high and connect to a rack mount router and feed with PoE.
So many ways to skin a cat...
