Steam Frame owners can stream without the bundled wireless adapter, according to MIXED's report of Valve's tracker reply. Valve recommends a 5GHz router wired directly to the PC, with the headset connected over Wi-Fi.
The same October 3 reply says many Linux configurations already work through Steam Link. But Valve's support guide still limits full support for SteamVR and adapter streaming to Windows, MIXED reports.
The router replaces the adapter's wireless path
Valve confirms Wi-Fi-only streaming as a supported mode. Its advice puts a cable between the PC and router. Connecting both the PC and headset by Wi-Fi falls outside that recommended setup.
The guide still recommends the included 6GHz adapter for the intended streaming experience. The reply gives no latency, bitrate or resolution figures for router-only use, so buyers have no measured comparison with the adapter in these reports.
Valve also describes Multi-Link, which sends packets over multiple connections. When both paths are active, Valve says streaming should continue if one drops.
Linux compatibility depends on more than the adapter
Valve expects a Linux PC that already streams to Quest through Steam Link to work with Frame too. That gives existing Steam Link users a useful compatibility signal, while the guide still describes desktop Linux and Steam Machine SteamVR support as incomplete.
For the adapter itself, Valve lists SteamOS 3.9 or later, or Linux kernel 7.2 or later. The reply says further software patches are in progress, without a timetable. Those requirements concern the adapter, so they should not be treated as a blanket minimum for every router-only Linux setup.
