My interent is constantly cutting out through out the day at random times, sometimes for just a couple seconds, other times for multiple minutes. This is only happening to my wired PC and not any of the wireless devices in the house. I am the only system that is wired straight to the router. When I go check the router to see if the lights are off or to see if the entier internet is down, all I see is that the Archer A7 isnt even showing that my ethernet cable is plugged in. If I switch the ethernet cable to another port it picks it up instantly and ill have internet again until it decides to not recognize that an ethernet cable is plugged in anymore and ill have to either wait for it to reconnect or just switch ports again. I did notice today that even though the router itself didnt show the ethernet was connected, when I went online and checked, it still showed my PC was connected. So im not sure what the problem could be. This has been happening on and off for a while now and I have tried trouble shooting it myself but I cannot seem to fix it. Not sure if this matters but I am using a flat 75' ethernet cable from my PC to the router. Any advice would be helpful, thank you.
