I have the Flint 3 and using firmware 4.8.1. previously I was using an Asus router. At one end of my house the signal is weaker but on the Asus the devices would connect and stay connected to the 5ghz signal. With the Flint 3 the devices regularly drop the WiFi and I would have to reconnect. I do get a sufficient throughput when connected.
This does occur on several devices.
How can I improve the connection when signal is weak?
