Hi Guys,
Been having issues over the past two days with slow Lan speeds compared to WiFi, which I seem to not be able to fix.
Background
I've gotten new 5G internet connection (Rain 5G - South Africa), that I've connected to my network to replace my 4G Internet. It's not fully setup yet, but I've been able to achieve anywhere between 50mbps to 100mbps through WiFi using my phone. This will eventually increase to around 200mbps or 300mbps after I've done proper antenna installation.
The 5G Internet comes with a Modem/Router/Antenna (HUAWEI 5G Outdoor CPE - N5368X https://consumer.huawei.com/za/routers/5g-cpe-pro/specs/), with a single RJ45 ethernet port to connect a router or computer. Because this modem will eventually be installed outside next to a wall, far away from all my devices, I need to make use of a router to connect my two PC's, phones, tv's, etc. to a single network.
The routers I have available and used are:
Huawei B315s-936
Netgear D6000
Network Setup
I have the 5G Modem in "IP Passthrough" Mode, which disables most router features (WiFi, DHCP, NAT, Firewall, etc) so it can be handled by a connected router. The 5G Modem is then connected via ethernet cable to the Lan/Wan port in the above mentioned routers, then my devices are connected to the router. The connected router handles all the router functions that have been disabled on the 5G Modem.
The Issue
My download speeds through WiFi on my phone are great, achieving anywhere between 50 to 100mbps, but my computers that are connected through the Lan ports on the router, have a lot slower speed than the WiFi, mostly achieving anywhere between 10 to 20mbps.

Attempted Fixes:
I've tried the following to fix this issue:
Bought New Lan Cables (CAT 7)
Updated/Installed Network Drivers for Motherboard (Asus Z87 Sabretooth)
Updated Windows 10 and All Drivers
Disabled Windows Auto-Tuning (Turned Back on after testing with it off)
Disabled Large Send Offload (LSO, turned it back on after testing with it off)
Set Ethernet Duplex settings to 1.00 Gbps Full Duplex
Disabled IPv6
Used Both Routers available with the same result.
Conclusion:
I've got no idea how to fix the issue and how to proceed further. A family member has recommended that I buy a new router (Netgear XR500) to fix this issue, but even with the current routers I would at least expect 100mbps through the Lan ports, so I'm uncertain if spending money on a new router would fix the issue. Any idea on how to proceed or potential fixes I can try?
