Extremely unstable wifi only in bedroom
As of the past couple weeks, my wifi, and specifically 5g quality has drastically dropped. I used to get over 200mbps down and now barely hit 30. My bedroom is directly down the hall from my router, 1 step outside and it is instantly 4 bars and stable, 1 step inside my room and its permanant 2 bars and contantly disconnecting. It will get stronger if i move further away from the router as long as its not my bedroom (hitting over 200mbps again when standing in kitchen, which is further from my router than my bedroom). My PC, Phone and TV are all having this issue. Nothing in the house has changed between having perfect connectivity and now. Does anyone know what could be causing this issue, why its suddenly happening now and how to fix it? Its becoming unusable
