@magouero said in wifi disconnect: @György-Farkas Köszönöm. Szívesen. The only difference is: "config interface 'wan' option ifname 'eth0.2' => here you have eth0 option proto 'dhcp' " Do you know what this " .2 " means ? I don't know too much. eth0 is a physical network interface (a hardware device), eth0.1, eth0.2, ... are virtual network interfaces (not an existent hardware device but are linked to one). root@Omega-5BE1:~# ifconfig apcli0 Link encap:Ethernet HWaddr 42:A3:6B:00:5B:E1 ... br-wlan Link encap:Ethernet HWaddr 40:A3:6B:C0:5B:E3 ... eth0 Link encap:Ethernet HWaddr 40:A3:6B:C0:5B:E3 Interrupt:5 ... eth0.1 Link encap:Ethernet HWaddr 40:A3:6B:C0:5B:E3 ... lo Link encap:Local Loopback ... ra0 Link encap:Ethernet HWaddr 40:A3:6B:C0:5B:E1 Interrupt:6 Do you have an Ethernet Expansion? Did you modify any network / firewall config files? It seems the DHCP client is working well on my almost "default" Omega2+ (Wifi AP 192.168.3.1, client 192.168.100.x connected to my Internet gateway).
