I have a AR750 Slate. Love it… it does what I need and more 85% of the time… I have set it up using the 2.4G to connect to any public network and using the 5G as an “internal” network. I have no issues connecting to maintaining the 5G network but the 2.4 drops its connection semi-regularly. it does re-connect most of the time… but not so good for realtime activities… voip etc…
im on the latest firmware and also using the supplied power brick just to be sure??
