I have a raspberry at a very remote site where the wifi range is not that great. I am using a USB wifi with the antenna to connect to the wifi. Should I disable the onboard wifi in this case as I am using external USB wifi.?
Also, is it safe to keep both the interfaces enabled (USB wifi + onboard wifi) on static IP address connected to the same ssid.? Will they create any clash.? I was planning to keep both the interfaces enabled, just in case if one fails for some reason, another interface can keep the things going.?
