The desktop hardware upgrades continue – we mentioned the PCIe adapter for solid-state drives in a previous article. Where did the old SSDs go? They weren’t wasted; they were removed and installed in the new computer I bought (a year ago).

The new machine has impressive hardware specs: 2.5G dual network ports, PCIe 4.0, and WiFi 6

Recently moved, and the room lacks a dedicated router for networking. Devices connect via wireless network. The ASUS motherboard desktop’s wireless card performance is lacking, possibly due to router wireless access or slow upload speeds between local networks, resulting in poor speed between machines. A new 2.5G NIC was purchased and installed in the desktop.

Network Instructions

The machines still use the original wireless network cards for internet access, but are directly connected with a network cable. Both ends have 2.5G network cards. How to connect them via Ethernet is widely documented online; remember to disable firewalls and designate one machine as the gateway.
