Windows 7: computer hangs going to sleep when there is lan activity

computer hangs going to sleep when there is lan activity

Hi all - here's my issue. Just got a new motherboard, Z270N-WIFI, new build of win7pro x64 running on it, everything is awesome except this sleep issue. Here's what happens

1) If firefox is NOT open, sleep works just fine

2) If firefox IS open, upon entering sleep (S3) mode the monitor shuts off, the cpu fan continues to run, the ethernet activity light continues to blink, the keyboard is unresponsive, and the only option is to physically power off and reboot. Its like it hangs halfway into trying to sleep

3) If firefox IS open, but then I unplug the ethernet cable, the computer sleeps just fine.

Btw its not just firefox, it happens with any browser.

I tried deleting then reinstalling the lan drivers, to no effect. I also tried the lan drivers directly from Intel, to no effect. Current drivers are from gigabyte and are the most current for my motherboard..

Also, not sure if this is related, I've got these annoying #2 references in device manager as you can see that would be nice to get rid of..


Attached is the network section of my device manager. I've made no changes to the system other than to install the drivers and then went in and unchecked "allow this device to wake the computer" on all items. I also tried disabling wifi and bluetooth, which had no effect. Any advice is appreciated..

There is normally a setting wake on lan activity or similar. Sometimes it can be in the BIOS or network card settings
