I understand your point, it seems quite unusual that it functioned properly despite the usual restrictions. Make sure to handle 320ft cables with care—they’re very close to the 100-meter limit. Even though Ethernet cables are meant for up to 100 meters, minor corrosion or damage can cause failure. Always opt for high-quality cables if you want to push boundaries.
I own older TP-Link and Asus routers in my storage that I don’t know how long they’ve been used but they’re 802.11b devices and still work well... provided I stick to 10mbps Ethernet ports. I’ve had two such units fail—one due to lightning damage and the other because of a user error installing third-party firmware.
Given your plan not to use Wi-Fi, it’s possible you could use a basic $25 router with basic LAN and WAN ports. You’ll likely end up using the default settings, setting a password, and turning off the wireless radios. If you’re concerned about durability, consider buying an extra router; otherwise, you’ll save more than you think by avoiding expensive industrial models. Most failures come from power issues rather than the router itself.
