Just to make sure you see it..... installing the Microtik SFP everything resolved completely and I get the full speeds

This is the Mikrotik one I used:

MikroTik S+RJ10 https://www.amazon.com/dp/B078SNK1MY?ref=ppx_pop_mob_ap_share

Plugged the Cat 6 cable from the 5GbE port on the BGW-320 to the S+RJ10 to my Mikrotik CRS305-1G-4S+IN. The CRS recognizes the 5GbE connection with no issues or additional configuration. The problem I have is this particular CRS model won't achieve wire speeds while being used as a router. It won't use the switch chip while also handling dhcp. As a managed switch, it achieves up to 10GbE with HW offloading, no problem. So connecting this to a 5GbE USB adapter to my PC achieves around 4GbE consistently now: USB 3.0 Type-C to 5GbE Adapter:

This is how I have it set up in my house. I have the Ruckus POE+ switch to distribute the Cat 6 throughout the house and also connect to the 3 APs I have.

Edit 2: Main "link" https://www.amazon.com/gp/product/B078SNK1MY/

This is from the seller I bought the one pictured above, should've been legit

This is the next attempt recommended by a friend. He ordered both, and the one from GETIC was perfectly fine.

Note: If you go to just the "MikroTik S+RJ10" Amazon page it doesn't seem to show you the actual seller, so in those 2 links I went to their stores and purchased.
