What to know before buying
Listing details to confirm
The listing is inconsistent about operating-system support: it names Mac OS generally but specifically excludes macOS Big Sur, and its system list includes Vista although the stated minimum is Windows 7. Check driver support for the exact OS version, particularly Linux and macOS. The claimed 1300Mbps total corresponds to separate stated maxima of 400Mbps on 2.4GHz and 867Mbps on 5GHz, not a single-band rate. The listed frequency range and USB speed comparison also warrant checking if exact specifications matter.
Who is it for?
A good fit for
- Desktop PC or laptop owners seeking a USB Wi-Fi adapter with dual-band 802.11ac support.
- Buyers who want a Soft-AP option to share a computer’s wired connection over Wi-Fi.
- Users prepared to confirm driver support for their specific operating system, especially Linux or macOS.
Less suited to
- macOS Big Sur users, which the listing says is unsupported.
- Buyers who require assured Linux compatibility or independently verified real-world speeds.
