We use the Wiz610io module in our devices for communication over TCP/IP.
However the link is hardly established in the most of the cases.
We use mainly Mikrotik devices, the Wiz610io is connected directly to this Mikrotik router.
Auto-negotation never worked, the only way to get it working in some cases is to set fixed 10Mbps speed. However most of the cases the link will never come up, or it will try to come up but after 1-2 secs the link is down again. This goes on forever.
Does anyone has any idea what might be the problem with this device?
