turning old pc into router?
I've noticed many videos showing people converting old PCs into routers with OPNSense. What's the value? It seems there are plenty more choices, charts, and settings—most of which I probably never use, and most I won't even bother understanding. Any real advantage? My current router is a Linksys WRT1900AC. I have several old PCs lying around that I could work with. I'm out of ideas for what to do with them, so maybe I'll just try it out to see if it's worth the effort before investing time. The PCs I have: two AMD single-core Intel Core 2 Duo 2.x models (3.x, 4 GHz, 16 GB RAM), four Intel Core 2 Duo 2.x models (4 GHz, 9 GB RAM), one AMD Phenom X6 3.x (12 GB RAM), and eight Intel Core 2 Duo 2.x models (8 threads, 2.8–3.06 GHz). I also have a 4 GB RAM system with an i7-930 4-core, and a 9 GB RAM system with an i7-930 8-core. About 12 GB RAM in one of the Phenom X6 units. Do you think more processing power helps? Will it speed up internet? What are the benefits and downsides of using a PC as a router versus my current setup?
the goal with an old computer is to capture weak signals or limited cables / special conditions here you have a USB dongle that functions as a wifi receiver OR router https://wifi.360.cn/easy although it's rated for 2 antennas 300mb/s A/b/g/n (non-ac) i can only achieve up to 150mb/s anyway, which is about 25 CNY ~ USD3.6 it's useful for old pc mining with hdd...?
I reside in a compact studio space. Every corner of my small apartment features complete high-speed connections. This setup offers no extra value, so I opt for it. I haven’t engaged in any mining activities. Instead, I own numerous computer components and unused PCs that I use for personal projects or to assemble machines for others. There are around 12 monitors, 50 keyboards, and a variety of GPUs. I’m passionate about technology—especially computers and smartphones.
Usually, unless you're unfamiliar with solutions like opnsense or pfSense, you probably don't need them. These operating systems provide very detailed control over network traffic both inside and outside networks based on your setup. They shine as routers between modems and local area networks where data flow is heavy—especially for time-critical applications. Ideal devices are those with many network interfaces, whether via USB or PCIe cards, and functioning as access points. If you plan to enhance your existing Wi-Fi, better focus on preparing professional-grade equipment like Ubiquiti or Cisco instead.
Enterprise-level solutions are available through PF-Sense, offering products suitable for business environments. For those requiring such capabilities, this remains the most affordable path. Enhanced protection is another advantage. Adaptability is also key—users can integrate Ethernet, direct copper, or fiber seamlessly. Comcast Gigabit Pro serves as a prime example: it delivers 2 Gbps symmetrical fiber speeds, but full performance depends on using their SFP fiber port via the included media converter. Consumer routers generally struggle with high-speed internet needs. PF-Sense’s shortcomings include limited internal switching and poor compatibility with many Wi-Fi cards, necessitating an access point for wireless connectivity. Most users engage with PF-Sense either to understand its inner workings or to leverage its cost-effective advanced features.
