Strange switch Behavior
Hi,
We have made a brand new installation to our local network with a simple setup:
WAN -> Router -> Switch (TL-SG1016D) -> 16x Clients (some windows pcs, some eap225 access points)
Initially some of the connected pcs was not reaching internet, so I did following tests in all problematic pcs:
ping from PC to Router -> 11ms responses with no packet loss. At some moments the ping drops to <1ms (the expected latency for a LAN)
ping from PC to PC -> always <1ms
ping from PC to 8.8.8.8 -> almost no response, but it responds fine at the same moment that the ping to router shows <1ms
So I spent a whole morning testing all cables, replacing patch cords, doing a lot of tests.
At some moment I realized that it might be an IP conflict (my router uses 192.168.0.1), so I made the following test:
Connected to port 1 of switch my router, and one other ports my PC. (just two cables into the switch, no interference of any other equipment)
1. Did a ping test to 192.168.0.1 and the same issue, high latency, no ping to 8.8.8.8)
2. Disconnected the cable that links the switch to the router, and did the ping to 192.168.0.1.
3. The ping STILL RESPONDS.
So I'm assumming that for some reason the switch (although unmanaged) for some reason is responding to 192.168.0.1 address.
Did someone found any issue like this? I have exactly the same switch, router and access points in another site, and it just works fine.
This switch have port isolation and loop prevention, I tried enabling and disabling both, but the same result occurs.
