Your desktop is a beast on paper, but the moment you hop on a video call or pull a large file over Wi-Fi, it feels like it's fighting the network. Wired Ethernet helps, but Bluetooth headsets and peripherals still lag.
The Jaycar AX5400 PCIe card drops straight into your Windows 10 or 11 desktop and gives you tri-band WiFi 6E plus Bluetooth 5.3 in one slot. No dongles cluttering the USB ports. No signal fighting through a wall from a separate adapter.
Intel AX210 silicon handles MU-MIMO, WPA3 encryption, and OFDMA so your connection stays stable even when the rest of the house is maxed out. The low-profile bracket fits compact cases, and the included heat sink keeps it cool under sustained transfers.
In the box: adapter, Bluetooth cable, antenna, baffle screws, manual. Slot it in, screw on the antenna, reboot — your desktop finally matches what the rest of your gear can do
