Ok , so il try and explain as best as I can ..
my work has routers and switches across the building , the router or group of computers in question is the ones in the top office wich are connected to router lets call it "office router" . now a few pc's connect to this router from the contractors office and all the pc's seem to drop connection or get limited connection issues using WIFI or Wired in , and other times .. DNS errors cant be reached and so on ... I have replaced that router and the problem persists , now I am not using the WAN port , just the 4 others to connect them into the network. now I have all the pc's set to auto detect ip and DNS settings so they dont get conflicted. Has anyone had this type of error with success in fixing it? I am now believing that it could just be a bad wire running from the server room? because it works perfectly fine at random it kicks employee's from the point of sale software screens as well. Any idea's ? or comments ?
Thanks in advance guys!!
