System disconnects from building antenna during sleep.

System disconnects from building antenna. When set to set and reopen. My building is wired with antennas? throughout each floor and across each floor.

This was done a long time ago when it frequently did not connect. Now with the wodows 10 updare it totally disconnects. Thanks Microsquish.

Have you set Power saving mode to Maximum performance in Wireless Adapter setting under Advanced Power Options?
You could also try switching to different DNS address(OpenDNS, GoogleDNS etc).

Power saving mode is set correctly.
I use OpenDNS.

This is not a paid system. WiFi sense on. No changes to system. Originally about a month ago the system would cut off when coming out of Sleep and I just Disonnect and reconnected. After the current Win 10 update it totally disconnects. There were/are no changes to setting. There is no password protection.

One thing I noticed after the Creators Update was that on resuming from hibernation my WiFi would only reconnect automatically about one in three times. It always used to reconnect every time.

Paradoxically, the fix was to turn ON "Allow the computer to power off this device to save power". It seems this ensured it was reinitialised properly when resuming from hibernation. Odd, because the conventional wisdom is to leave this setting turned off.

I had problems with Hibernate awhile ago. I was told by some pros not to use it.

Hibernate or Sleep, the problem may be the same - the WiFi adapter is not being properly reinitialized on waking. Turning on "Allow the computer to power off this device to save power" worked for me, it may well for you too.

BTW, hibernate has worked perfectly on my machine, from W7 through all version of W10. A few systems can have problems, seems to vary by manufacturer.
