might i suggest that in most cases just installing another bt connection and setting up a vpn is the most reliable way forward.
if a hard link can’t be established, substitute a 5g router.
or just try 2 asus router’ s using 2.4Ghz mesh to create the back bone.
but imo. the 5g with a vpn is going to work surprisingly well.
an theres also starlink.
