Build your own modem, router, or Wi-Fi setup at home.
Build your own modem, router, or Wi-Fi setup at home.
It seems you're asking about achieving high-speed Wi-Fi performance. Whether it's possible depends on your setup, but you could explore options like building your own modem/router, using PCIe coaxial adapters, or installing a PCI Wi-Fi card to boost connectivity.
I question the feasibility of the approach but proceed with the reasoning. Unless you're prepared to invest in high-end equipment costing thousands, it's not practical. A simpler solution would be to utilize an existing cable-modem and connect via Ethernet, allowing the PC to act as a router. Regarding using a WiFi card as an access point, this is indeed achievable.

No, I don't deal with enterprise-level hardware. Link to what? A WiFi-card? Practically all modern WiFi-cards can be used as APs, there's no point in linking to any specific ones.

When planning DIY networking, consider each component individually—modem, router, and switching options. I didn’t specify your internet type, so I’ll focus on the modem side for you. There are no PCI/PCIe coax modems; most DSL setups use older models capped at 15Mb/s. For cellular connectivity, there are various solutions available. If you have coax (DOCSIS), you’ll likely need a standalone modem such as a Motorola SurfBoard. For routing, an old computer with two Ethernet ports works, or you can purchase dedicated router devices—often x86 embedded systems with 4–6 ports—or opt for specialized routing hardware. Basic routers require three elements: internal and external interfaces, NAT for shared public IPs (usually managed via firewall rules), and a DHCP server. With dedicated hardware from brands like Ubiquiti, Mikrotik, or Cisco, you can use the included software. For switching, you can build it yourself by connecting multiple ports together, especially in embedded systems with four or more Ethernet ports. This approach offers lower latency than custom switches but isn’t as fast. Wireless setups usually need separate access points instead of direct PCIe/USB adapters on routers, since DIY OSes like PFSense have limited wireless support. If you prefer an all-in-one solution, consider a ready-made wireless router and install open-source firmware such as Tomato or OpenWRT. This approach offers better value than assembling everything yourself. Still, a separate modem will be necessary.
He's attempting to assist because your data seems flawed or confusing. It doesn't make sense for you to need extra speed beyond what Wi-Fi can provide. Clarify your needs so we can offer practical advice. Trying to set up something unfamiliar will likely fail. Save time, effort, and money by choosing a standard router instead.
PCI Docsis cards are no longer produced. The only one I've seen was from Docsis 2.0, and most not all cable companies don't permit Docsis 2.0 equipment on their networks anymore. Also, achieving 2 Gbps over WiFi isn't technically or remotely feasible. I'd recommend asking for 1) Your ISP, 2) The package you're using, and 3) What you hope to achieve.
