I have created several temperature network servers with arduino nano + ENC28J60 (old 10pin header "large IC") + DS18B20 sensors and worked like a charm for the last 3 years.
I just build a new one, and since I could not find the old 10pin ENC28J60 module, I used the new 12pin ENC28J60 module with the smaller IC.
Everything works perfectly (ping the IP and browse the server's webpage) when connected directly to my PC or trough my local TPlink switch network.
But when connected to ANY Cisco switch I am unable to ping or access it! >:( >:(
It seems like this module cannot negotiate with Cisco Switches while the old one had no problem.
I managed to operate it using a Netgear gateway (cisco on the WAN side and Arduino on the LAN side) but it is not an acceptable solution.
Also tried this ENC28J60 with the same results (not working)
Has anyone else experienced / solved this problem??
Any help would be appreciated.
Thanx in advance,
