I didnt find it any worse, just no discernable better coverage wise. Of course I get better speeds on gig1 and multi tasking I cant say I notice a difference. I have multiple devices doing multiple video conferencing plus gaming simultaneously. It's not handled perfectly but it's just ok most of the time.
Did you not get a seperate router with such issues you had and just use the hub as a modem?
I'm hoping to try the wifi pods next and if still not satisfied invest in cat6 router or mesh.
