It seems that a DHCP problem encountered on an EMX card is exactly the same on G120HDR module.
With a CISCO 857 router as DHCP server we always got the same sequence on DHCP request. DHCP DISCOVER and DHCP DECLINE as stated in this post
Every other client is working properly ( iPhone , notebooks, servers )
We are using version 220.127.116.11 ,older versions give the same behavior.
We have noticed that Microsoft is responsible of the DHCP client code, but this is a bit annoying as DHCP address distribution is usually not a problem and not negotiable in customers plants.
Any idea how to fix that ?
We can send yo WireShark log or an old CISCO 857 if you want to investigate the problem.
