I have a NUC (D34010WYKH) with a 7260 AC (w/ BT) card w/ Win 7 and I was running fine on 16.x (not sure which version) and after upgrading to 17.0.6 I had this issue (no wifi after wake from sleep). Upgraded to 17.1 and still had the issue (tried turning U-APSD off). The wifi sys tray icon was buggy as well (sometimes it would show not connectivity even though things were fine) despite a second uninstall/reinstall. Win 7 was fully patched and I was using all the latest NUC drivers.
After uninstalling the Intel Wireless drivers, rebooting, and then installing 16.10 (the IT version) I was back to good. The wireless performance was even a bit better with 16.10 vs 17.x though I've not been very impressed with the NUC antennas.
