ANTMINER L3+ router connectivity issue

Just setting up my test L3+ before I get my march batch in. Miner boots up properly but can't seem to communicate with the router. When it's plugged in the router shows a red light. No fault codes or anything on the L3+ and I have tried 2 different miners and multiple different Ethernet cords and ports on the router. I have a Netgear R7000 for this setup. Is it the router? Or maybe something to do with the IP? Haven't seen any problems like this online. Looks like everyone can find the IP no problem as soon as they plug in. Checked for connected devices as well as all available IPs on the command prompt and don't see it anywhere.

- router has been fully updated and allows DHCP
- is there a certain type of Ethernet cable required? I have CAT 6
- IPv4 is different than gateway access IP would that effect anything?

Thanks for the help!
