Just 40 meters beside our IT server room, there is a clinic and there is an ethernet cable is going from IT room to this Clinic and it is connected to a small wifi router , there are 3 devices connected to this wifi for internet, since two weeks the wifi connected devices are showing there is no internet access, then I checked the internet line going to the wifi router by connecting that line directly to PC , "it is working fine", I thought it is a router problem then I changed the router then also the same problem("no internet"), then I connected this line to one small switch and devices are connected to this switch, then also no internet available. the only problem I can see, after I directly connecting the line to pc I can see in network properties "connection speed=10mbps" usually it is "100mbps".What is the problem?
