I'm trying to use my Archer C24 to extend different Wifi 5.8G hotspots, like a Windows 10 hotspot. So, I'm extending a 5.8G main wifi network, without setting a 2.4G main, since I don't have one. Sometimes it works, I can navigate without problems in the EXT network. But after half an hour of so, connection drops, and status says connected (to main network) but with no internet connection. Main network works perfectly (as I can connect any device without problem), but the repeater cannot connect. I then try to reconfigure it, and it usually won't work again for some time. It's SO unstable, I cannot use it this repeater.

HW version is ES rev 1.0
