Recently bought a D6200. Wireless 2.5/5G work flawlessly. However I cannot plug more than one computer into wired ports. I am using DHCP with DHCP IP reservations (14 IP's). If I use more than one wired port, the addtional port may work for a few seconds or minutes, then all wired ports stop working. If I remove all but one port, the original single port stops working. Does not matter which ports but only the number of ports I try.
Behavior with > 1 port connected is strange. Sometimes I can see the entire network from a PC but not login to router or see the internet.
If I remove all but one port, That port's PC connectivity returns to nornal.
I upgraded firmware to v*_20 when I received the unit.
Any ideas ?
