I've been using netbird, but not self hosting, for about 30 days on two devices, tplink_archer c7 v4 and totolink_x5000r, with wireguard kernelspace in openwrt snapshot without any problems so far, to be honest at sometimes tplink_archer c7 v4 disconnects, but I think the problem is the hardware, few resources, because totolink_x5000r is fine.

And I opened https://github.com/openwrt/packages/pull/23926 to add kmod-wireguard as a dependency for netbird, and to work in userspace you probably also need kmod-tun, maybe I add kmod-tun as dependency too? I just don't think it's good to change the default to use wireguard userspace

@masx200 is it still an issue for you with the latest NetBird versions?

@nazarewk, the 'issue' persists, but it is now a design decision, you can see my reasoning here https://github.com/openwrt/packages/pull/23926, and yeah, I believe this can be enhanced by documenting this behavior and integrating the env NB_WG_KERNEL_DISABLED with uci, and the user can install kmod-tun and use wireguard in userspace if they choose to. That's what I think.
