RE: XPS 15 9550 - Wifi drivers causing Bluescreen
Same issue here ! (driver version 1.555.0.0 - with i7, 16Gb, QHD+, Win10 Pro)
Seems to happen when I "stress" the Wifi connection (about 30 MB/sec down)
I freshly reinstalled with the Dell official ISO, and have updated all drivers and UEFI with versions provided on Dell website.
