Use several Wi-Fi cards for improved performance.
You're asking why only one Wi-Fi card is allowed per system for internet access. The reason comes from how network infrastructure is designed—servers typically use multiple network interface cards (NICs) to handle large volumes of traffic and maintain stability. Home users usually don’t need that level of redundancy or bandwidth, so they’re limited to a single card. Your setup with the AX Wi-Fi chip on an MSI motherboard works fine for your needs, but it still relies on one NIC. Upgrading to a dual-NIC setup like the ASUS AC-WiFi PCE-AXT58BT could help you get closer to the speeds you’re seeing, especially if you move closer to the router or use a better antenna. Just make sure the cables and placement are optimized for both distance and signal strength.
AX 5GHz offers comparable coverage to AC 5GHz WiFi. For 6GHz you need 6E, which provides less reach but switches to 5GHz or 2.4GHz based on signal strength. Servers use several NICs for backup and balancing, but this doesn’t mean a single data stream becomes faster. Imagine multiple lanes on a highway—your vehicle can only move in one lane at a time, while others can travel similarly fast. This analogy helps convey the idea, though it’s not perfect. Adding more NICs boosts capacity for several connections simultaneously, not just one. SMB3 can support this locally between compatible clients without leaving your network.
There are third-party tools available that may assist in merging the speeds of two cards, such as Speedify.
The actual solution is simple—just lay a wire. There’s always a method available. Just follow the path and get it done.
WiFi operates on a shared channel, and external influences like interference can cause significant changes in performance even over short periods. Placement and orientation of antennas are crucial elements. The AX card doesn’t specify using cables to extend antennas, while the AC card does—introducing another variable. Physical barriers such as walls will obstruct the signal, reducing speed with distance.
View WiFi as one shared Ethernet connection, similar to how hubs once operated. Each channel functions like its own port, meaning with WiFi 6e you'd have three distinct ports. Devices on the same channel exchange data together, and since WiFi transmits in only one direction at a time, overall speed is constrained. If you link to two channels simultaneously, you might combine them—though this isn’t officially supported. Rumors suggest WiFi 7 could let you connect to all three channels concurrently for seamless merging. Currently, Windows isn’t built to manage more than one internet path at once. Workarounds exist, but for heavy data transfer wired connections remain the best choice.
