So today i've decided to move the family PC to my room so i can use it on my room for my online classes. Problem is the signal is weak. So to elaborate it our WiFi router is on first floor, and my room is on the second floor. While using a WiFi USB Adapter i can only get up to 2-3 bars on my room. So i bought an WiFi Repeater online and fixed the issue on slow signals, but unfortunately it came with some downsides. First is its not stable sometimes it will disconnect on its own on my PC, or even give me high pings on my games, and i can really see the difference of speed on my internet before i was using the PC besides the router, and now that i am using a WiFi repeater. So i want to fix it again by using a LAN Cable that will come from my main router (1st floor) to my PC (2nd floor) will that resolve my issue on having a connections problems on my PC?
