Dear All,
I have one customer there are experiencing high latency from their LAN. When I tried extended ping from the router the latency was 124ms to 144ms. When the customer is pinging from the LAN the latency is 260ms. We the customer disconnected the LAN and connected his laptop directly to the router and checked the response is same about 260ms.
Any suggestion on the cause.
The ping responses are as below,
