Re: [lwip-users] FW: Problem with renewing DHCP after link down/up with the new LWIP V2.0.2

[simeon.trifonov]

I modified my code now, so I don’t set the IP address and mask to 0 anymore. Still the same problem with the DHCP. It works only after power on. Renewing doesn’t work correct on my device.

Could you please stop quoting over 80kb per mail? Thanks.

Ehrm, why do you do that? When DHCP is enabled, DHCP has control over the IP addresses. If you mess with them manually while DHCP is enabled, it's not strange at all that things don't work.
