My PC 3 can't obtain ip adress by DHCP because the BRIDGE 1 is LOST. I need to fix a static IP. Before, BRIDGE 1 had a static ip adress 192.168.1.253 and it worked. I dont know how but the BRIDGE 1 lost his configuration.
I already scan 192.168.1.1 to 192.168.1.255 and I dont find BRIDGE 1
How can I find BRIDGE 1?
