Yesterday I uninstalled the Broadcom (bcmwl-kernel-source package) driver and since then using "open source" (brcmsmac) the wireless network no longer drop. So it seems that this confirms, at least in the case of Broadcom, that the failure is in the proprietary driver. However, after boot and when returning from hibernation "iw reg get" still shows "country UZ"... But that is not making any difference because the wireless network showed no further failures.
