Hi, I faced a problem with DHCP client in lwip 1.4.1 with one specific router (not sure what exactly it's type is as it is installed at customer's house). Same router works fine with Windows PC, i.e. PC get's IP from router and connects to the internet.
Below is the DHCP module trace. I wonder if this is one of: - known issue in 1.4.1 fixed in latest - issue with router not related to lwip - unknown issue (bug) Trace: dhcp_start(netif=200100A4) et0 dhcp_start(): starting new DHCP client dhcp_start(): starting DHCP configuration dhcp_discover() transaction id xid(4d9ba518) dhcp_discover: making request dhcp_discover: realloc()ing dhcp_discover: sendto(DISCOVER, IP_ADDR_BROADCAST, DHCP_SERVER_PORT) dhcp_discover: deleting()ing dhcp_discover: SELECTING dhcp_discover(): set request timeout 2000 msecs dhcp_discover() transaction id xid(958bf589) dhcp_discover: making request dhcp_discover: realloc()ing dhcp_discover: sendto(DISCOVER, IP_ADDR_BROADCAST, DHCP_SERVER_PORT) dhcp_discover: deleting()ing dhcp_discover: SELECTING dhcp_discover(): set request timeout 2000 msecs dhcp_recv(pbuf = 2000B51C) from DHCP server 192.168.1.1 port 67 pbuf->len = 300 pbuf->tot_len = 300 transaction id mismatch reply_msg->xid(4d9ba518)!=dhcp->xid(958bf589) dhcp_recv(pbuf = 2000B51C) from DHCP server 192.168.1.1 port 67 pbuf->len = 300 pbuf->tot_len = 300 skipping option 2 in options skipping option 23 in options searching DHCP_OPTION_MESSAGE_TYPE DHCP_OFFER received in DHCP_SELECTING state dhcp_handle_offer(netif=200100A4) et0 dhcp_handle_offer(): server 0x0101a8c0 dhcp_handle_offer(): offer for 0x1a01a8c0 dhcp_select(netif=200100A4) et0 transaction id xid(4ed75815) dhcp_select: REQUESTING dhcp_select(): set request timeout 2000 msecs dhcp_recv(pbuf = 2000B51C) from DHCP server 192.168.1.1 port 67 pbuf->len = 300 pbuf->tot_len = 300 searching DHCP_OPTION_MESSAGE_TYPE DHCP_NAK received dhcp_handle_nak(netif=200100A4) et0 dhcp_discover() transaction id xid(454b179b) ... and so on...
