Spoke to online help as my WiFi speed drops to zero when in dinning room. 2 rooms from router but with booster in middle on floor above.
was told that my router was too near my window and to move it and that should fix issue. This is difficult and with length of power cable etc can’t be moved in any meaningful way.
have followed advice as best I can ( with resets etc ) and now performance is worse.
Is this a network congestion issue as seems to be around same time each evening
