If you're experiencing poor WiFi reception in your room, there are a few things that could be the cause. The most common one is metal obstructing signals and blocking them from getting to their destination. Moreover, thick walls can block WiFi also in addition to the distance between the router and the devices. If this sounds like what's happening, try switching over to the 2.4 GHz band instead of 5GHz (if both bands aren't already enabled on your router). Furthermore, keep the router firmware updated if the WiFi is weak. Also, make sure for mesh WiFi, nodes don’t have too much space between each other when they form a mesh network—this will help improve signal strength as well!
