Hi, I’m facing to a problem with the renew of the DHCP after link down/up. With V1.4.1 all worked fine. Probably I’m missing something now. I call correct the functions netif_set_link_up() and netif_set_link_down() when the corresponding events occur. After power on DHCP works fine. But after disconnecting and connecting back the cable, I see that the discover-frame is sent from the stack and an offer-frame is returned from the DHCP server, but there is no reaction from the stack. Also the callback for status change is not called. I tried to call additionally netif_set_up() and dhcp_renew when link up event is generated, but there is no change. Can you give me a hint what I’m missing?
