With the help of Frédéric Pierret(many thanks again) I've recently updated my Qubes r4.1 fc31 to kernel 5.6-rc4(due lack of Nvidia rtx 2080 support under the old kernel). Now the NV card works properly but I've lost the WiFi connection (under sys-net vm). I must mention it used to works perfectly on the older kernel version(actually any version up to 5.6, including 5.5.9 freshly compiled). I also updated the sys-net vm kernel verision to 5.6-rcX but I still have the issue. the WIFI card is attached to sys-net:
