hello, this is my first time posting on here.
so I have a problem with my computer I'm not sure that the problem is the is coming from the ethernet cable, Ethernet port, extender, or the router its self. I use wifi a wifi extender for my pc in order to connect to the internet it is a NETGEAR - AC1200 Dual-Band Wi-Fi Range Extender I use it because of my local wifi/cable company cannot install the wifi router in the same room where my pc is. when playing any type of game from the steam store or when playing Fortnite it keeps disconnecting at inconvenient times I'm not sure if the problem is coming from my realtech 1.0 gigabit ethernet port because it was having trouble connecting to the internet when I first used the wifi extender it could not make a valid IP configuration now I fixed that that problem. it could be my ethernet cable since it's a cheap one. can you please tell me what the problem is.
