Issues regarding Wifi router
My Wi-Fi range suddenly became extremely weak. Right next to the router I get full signal and 30+ Mbps, but just a few feet away it drops to around 1 bar and ~6 Mbps. The Wi-Fi network doesn't even show up on the second floor anymore.
I've tested the same behavior from multiple devices. Could this be a damaged Wi-Fi antenna or radio in the router?
What tests can I do to determine whether the problem is the router's antenna, Wi-Fi radio, or something else?
I also tried to re arrange the antennas in certain angle nothing works lmk your thoughts and suggetions
