To add to sparksdls's response below, on my XPS 13 I go to Control Panel, Device Manager, select Network Adaptors, right click on your wifi device, select Properties, go to Advanced tab, then in the Property list scroll down to Power Output and you get the option to select percentages to the right of the Property list
Hi, so I was having USB C problems with HDMI. I found this post thru google search. I turned wifi off and viola everything worked... reconnected and everything still working. However, I'm concerned about the bluetooth and wifi connectivity and signal strength if I end up lowering the power to 75%. Can someone confirm how bad the connectivity gets? Thanks.
I lowered the power on my XPS 13 9350 with the Intel 8260 card and haven't seen any impact on my WiFi or Bluetooth.
