The same beta, SteamOS 0.4.3, also targets streaming reliability. It should reduce how often the dreaded 'Error 17' appears, which flags incompatible protocol settings between the host PC and headset, though that fix requires updating SteamVR to the 2.18.2 beta as well. Valve additionally says the update addresses wireless adapter connectivity problems that affected users in some countries, without explaining what geography has to do with it. Club386 speculates this could relate to the adapter's use of a personal 6GHz band, which is not permitted everywhere, China for example.

There is a ceiling here, though. Anyone wanting a serious jump in uptime will need to wait for headstrap-based battery designs to arrive, and Valve has said it is looking into modular batteries for the Steam Frame, lending some weight to earlier leaks about an Enthusiast Kit. That software-only ceiling is worth remembering, because iFixit's recent teardown found the Frame's battery is glued inside the housing rather than held by fasteners, so swapping in a bigger cell is not a quick fix. For now, these changes sit in the beta channel, with a stable release hopefully not far off.
