I have a network with a really high ping (usually more than 500ms) except for one laptop. And in that laptop the ping is usually 5ms.
I've tried: - using same model laptop - compare lan driver version - test on another cable/docking station - compare gateway, submask, etc. - enter with other user in the pc (the users are in a win server 2003 active directory) - run with all the other devices disconnected from the network. - disconnected the WIFI from the "fast" laptop so there is no chance to catch wifi networks. - compared with spiceworks and found no big differences. (Almost the same apps and fixes)
I do not have access to the router config and firewall. But that has been tested and nothing was found. And there is the laptop working through the same network/firewall.
What am I missing here? Help is really really appreciated.
Thank you in advance.
Im using speedtest.net to test. Basically the internet is slow and the problem seems to be the ping. There is switching involved. Although I do have limited access to almost all devices.
