High-speed dual-band Wi-Fi setup for Linux Ubuntu
High-speed dual-band Wi-Fi setup for Linux Ubuntu
Your system uses Linux Ubuntu and currently lacks wireless connectivity. It's challenging to locate confirmed dual-band adapters that work with it, especially since reviews often mention Linux incompatibility. You might need to rely on Ethernet for stable internet access. There are affordable Linux-compatible Wi-Fi adapters available, but availability can vary.
Choose based on chipset rather than final product for simplicity. Right now, Intel WiFi chipsets offer the top support, with Qualcomm closely following (around 90% performance on Linux). Broadcom works well on certain chipsets, while Ralink and Mediatek are decent but not top-tier. Avoid Realtek at all costs—it causes major stability issues and demands more CPU power compared to better options. PCIe is preferable for higher bandwidth and lower latency. I suggest the Intel Wireless-AC 9260, paired with the Fenvi FV-102 M.2 to PCIe adapter (available on AliExpress). Fenvi is an official Intel distributor and often has sales reducing prices by about $5, making it a great deal. We recently upgraded our system with these components and decided to pass them along to my sister for her new setup.
I installed the driver right away upon starting Ubuntu for the first time with your Intel m-pcie Wi-Fi card.
The drivers are part of the kernel. Curious to know—do you have the Intel Wireless-AC 7260?
This device includes a Broadcom chip (BCM4360), as noted on WikiDevi, making it suitable when properly configured—though only after installing certain specialized firmware. Nonetheless, I think opting for an Intel 9260 with an M.2-to-PCIe converter would be preferable. It offers lower costs and greater flexibility, enabling: 1) Easier future upgrades. 2) Cheaper replacement if the component fails, plus reduced physical footprint. 3) Built-in Bluetooth (Intel 9260 supports BT5.0). 4) Compatibility with laptops without needing an adapter. 5) Potential for software updates without replacing the whole system. 6) Upgradability to newer Intel models if required. 7) Lower power consumption, resulting in less heat generation compared to the BCM4360. It seems the Intel 9260 might actually surpass the BCM4360 in performance thanks to its broader spectrum support (160MHz vs. 80MHz bands) and better Linux driver availability—though Broadcom drivers are strong when supported, they lag behind Intel’s open-source efforts. In general, driver support matters less if the distribution is maintained; the BCM4360 currently lacks full Ubuntu PPA or AUR support.
