edit:
on the SG-3100 I have determined that I did not have the switch ports assigned/enabled to any vlans and after that it gave me DHCP on the lan ports and vlans. however I am still with the issue of some devices getting IP's and some not, on the same laptop over Wi-Fi nothing wired something. My travel AP does not support vlans so it has to be on the base level. and none of my non-Mac computers seem to be getting DHCP. And I don't know what caused it but I managed to crash my old router and ALL INTERNETs last night plugging in the new one to do a test. I went out and bought 4 manageed switches so I could break out all of my VLANs to test, and it was the only ez way to solve ingesting my multiple travel WAN VLANS ( local lan, Wi-Fi, Wi-Fi hotspot, wired LTE modem).
