Man, I’ve had problems with that line of switches too. Not that exact model, but similar.

First idea would be factory reset and do that a couple times.

Second idea is unplug everything, reboot, and wait. Then wait some more. Just when you feel like it shouldn’t be taking this long, give it another minute to plug your stuff in.

My particular managed model seemed to have a problem linking at different speeds.

Your Hue bridge uses an older/cheaper chip that is perfectly applicable for the device, but runs at a max slower speed. Try not connecting that. It caused all sorts of problems for me and terrible performance for all devices.

Eventually I returned my Netgear unit and got a TP Link thingy that’s been working great.
