I have a Canon 800D with WiFi functionality and installed EOS Utlity. It finds and connects my camera fine, but when I want to transfer images they transfer extremely slow (+- 5 minutes for 1 photo). When I do a speedtest with my phone (also WiFi) it goes really fast (40-50 mpbs) so the problem is in the camera.

I have tried to reconnect the camera to the pc, rebooted my router but the problem remains. Does anyone have an idea to fix this?
