I am using wiz105sr module with dhcp enabled. Sometimes module is able to get address using DHCP and sometimes it keeps on failing (DHCP timeout).
I checked the wireshark logs and found that the module keeps on sending BOOTP messages. In wireshark it says "Unknown BOOTP message type (182 or some other values) [malformed Packet].
I am not able to attach wireshark logs (its not allowed on the forum) so i am attaching a screenshot.
I restarted the module as well as my modem but still it can get the IP address.
