I have a new XPS 15, with windows 8.1 and a Intel(R) Dual Band Wireless-AC 7260 wireless card and it appears that every time I either hibernate or sleep my computer, on waking it is unable to connect to any wifi network. I'm able to reconnect by restarting my computer, running the wifi troubleshooter, or disabling and re-enabling the wifi adaptor. While this it not an absolutely terrible issue (now that I've found workarounds that don't include restarting my computer), disabling the adaptor did completely crash my machine once so far, so I'd like to get this fixed ASAP as I'd rather my new computer be fully functional to begin with, or things could go downhill quickly (I might consider returning it if things don't get fixed, but I'd really rather fix it as I have already transferred most stuff over from my old computer).

I've made sure all software on my computer is up-to-date, including the wifi driver (version 17.0.2.5). I have not installed any software that should interfere with the wifi adaptor.

Please let me know if this is a known issue and there are fixes, or if not if anyone has any ideas on how to fix it. Thanks!
