Valve updates SteamOS to improve your WiFi download speeds, and it’s available on Steam Deck with a couple of caveats
Valve has released SteamOS 3.8.14, a software update designed to improve WiFi download speeds on devices running the operating system, including Steam Deck. The update addresses a technical issue affecting WiFi performance where routers that incorrectly advertise their Modulation Coding Scheme (MCS) requirements were limiting connection speeds.
MCS is a wireless communication standard that enables routers to negotiate optimal transmission speeds with WiFi-enabled devices by conveying information about signal strength, connection capabilities, and available bandwidth. When routers misrepresent their MCS specifications, they can inadvertently restrict data transfer rates, negatively impacting download performance.
The changelog for version 3.8.14 is minimal, listing only two changes, with this WiFi fix being the more significant of the two updates. While the update is now available for Steam Deck users, the article indicates there are caveats to consider regarding its rollout or compatibility.
This update represents Valve’s ongoing efforts to optimize Steam Deck’s performance and user experience. WiFi connectivity is particularly important for portable gaming, as users frequently download games and updates over wireless networks. By addressing this router compatibility issue, the update should help Steam Deck owners achieve faster and more reliable downloads.
