RE: Really weak Wi-Fi signal - XPS 13 9350
thank you for the rapid reply. At the moment and until weekend I am at a location that is so small that I cannot move far away (>5m) enough from the Wifi spot, so I cannot "satisfactory" reproduce the problem. But I can still see missing ping responses when I test from the most distant position (5m+1wall) in this flat. Next weekend I will try to follow your suggestion regarding deleting the Dell driver, but I am reluctant to open the notebook because in Germany this may lead to loss of guarantee.
