SOLVED:

I wish I knew why for those that follow after. I changed a few things at once so I'm not sure if one of or combination of them was responsible or the fix.

I turned off TCP/IP on the WAN NIC. I rebooted the modem and router at the same time with cables connected.

Hm. Looks like hard to find right answer...

I need a little bit to explain the topic start question:

What system is better for network-related operation (i.e. firewall, load balancing, gate, proxy, media stream,...):
a) 1 CPU with 4-10 cores, hi-frequency
b) 2-4 CPU with 4-6 cores, mid-frequency

And how the cache in CPU L2 (2-56Mb) and L3 (2-57Mb) impact on network-related operation (in cooperation with NIC card) ?

Glad you have it working now. ☺
