I’m doubtful that Qobuz is at fault, but your router might be. Are you running wired or wireless to your streamer? If your router is more than five years old or was a cheapie when you bought it get a new Netgear lets say Nighthawk. If you are running wireless, try getting a Amazon (cheap) 100’ Cat 6-8 cable and run it to your streamer and see what happens.
All the best.
BTW, Qobuz and Qobuz Connect work fine for me. I hate their persnickety search engine, but that’s another story for another time.
