I am having an issue where new computers obtain the correct IP information on our wired network. IP address, mask, Gateway, DNS, etc. The problem is that I cannot ping the gateway. Only other devices that are on the same subnet.
I have been able to work around it but that is not consistent. On the problem devices I have cleared the arp table, purged and reload the remote cache table, flushed dns, and removed the ethernet adapter via the device manager then re-added it. Sometimes these methods work and other times they do not
We have a back up Comcast network and the computers work normally when connected there. Even prior to using the methods listed above. So my thought is that there is some sort of incompatibility between the computers and our Extreme switches.
The computers are Dell Latitude 5480 and 5580s and some Mac devices.
We use Extreme X460-G2 switches running firmware version 188.8.131.52.
Any thoughts on this would be greatly appreciated.
