USB vs PCIe wifi adapter
USB vs PCIe wifi adapter
Consider the trade-offs between your existing USB adapter and a new PCIe Wi-Fi adapter. A budget PCIe adapter might not drastically improve speeds beyond what you're already seeing, especially if your current performance is solid at 120 Mbps down and 35 Mbps up.
usb devices often rely on the usb chipset for communication, especially when not using usb3.0 or higher. pcie is built into the pc and doesn’t require a usb port, offering quicker data transfer directly to the cpu. graphics cards aren’t a concern even with pcie 3.0; an 8x 2080 ti works fine, and a 4x 2080 super should function with minor issues. at 120mbps speeds you’re likely okay. just confirm compatibility if using a wifi 6 router and card.
USB requires more processing power to handle data transmission. USB adapters typically feature compact antennas or lack external ones. PCI-e devices often include detachable antenna connectors, allowing you to place them farther from the computer. The metal casing and nearby walls can sometimes weaken the signal. If your adapter uses small antennas that go behind it, you can purchase additional ones for better positioning.
