The upstream router is a Linksys AC5400. I’ve connected in AP mode the GL-AR150, but as soon as it automatically updated into the 3.211, it stop detecting the ethernet cable. It took me some time to find out that the issue was firmware related, but, as soon as I rolled back the router to the previous firmware version (3.203) it get back to work immediately.
Do you mean you set up AP mode in web panel → more settings → network mode?
I just tried mine and it works OK. Any idea that could cause this issue?
Yes, I’ve connected the GL-AR150 in AP mode (in settings → network Mode) to extend my wifi coverage. The router have been working fine until the update to fw 3.211, which makes the router stop detecting the ethernet cable. I’ve changed the cable, and also the modem but the error continues. Once I rolled back to the 3.203 fw, the modem get back to work normally.
