I just received a brand new 15 R2 in the mail a few days ago, and have had nothing but issues with the wireless. It works fine under normal load IE browsing internet or streaming videos. When I attempt to download a game from steam or push it the signal slowly degrades before the wireless card disables itself. You are then unable to enable the card via hardware switch or right click enable. Any ideas? See video for reference.

I have uninstalled all killer software/drivers, deleted drivers, and reinstalled killer drivers from both killer website and dell.
