    Wifi doesn't connect on Startup but connects on Restart

    I have a laptop running Windows 10 Pro version 1607 that I use only once a week for a few hours. Every time I power up for my weekly session, the wifi fails to connect:
    Pinging with 32 bytes of data:PING: transmit failed. General failure.
    C:\>ping yahoo.comPing request could not find host Please check the name and try again.
    Sometimes I walk away for an hour; when I return, Ping fails again. But if I do a Restart, on the second startup the wifi connects and works normally throughout my session. However, if the system goes into Sleep mode, when I wake it up, the wifi fails again until I do a Restart.

    Can anyone explain this and tell me how to fix it? Thanks.

    Please open up device manager, find your wireless adapter, go to properties, Power Management Tab and disable the computers ability to shut off adapter to save power.

    I would also look up your wireless adapters MAC address and then, while you are connected, enter your router and "Reserve" an IP address for this MAC address.

    This allows your laptop to continue using DCHP assignments, should you move it, but says to all other device in house, this laptop gets this IP address.

    The process to reserve IP addresses is different with each router. If you post make and model it will be easier for people to assist.

    There is no Power Management tab in my wifi adapter properties. The closest I could find is this:

    You may be able to achieve similar results by heading to advance power management and under USB, disable USB Suspend setting.

    Any idea why Windows connects the wifi on a second startup, but not on the first? The wifi connects and works normally when I do an immediate Restart after a cold startup. To me, that indicates a Windows problem--if it can connect the wifi on a Restart, why not on the initial Startup?

    Can't answer that. It is likely something in Fast Start up or how Windows or the driver is treating adapter with regards to power management. While I think MS has done a very good job of allowing Windows 10 to run on a collection of devices your card is extremely old my technology standards. I have an old Dell that was built for XP. I bought new adapter and went through the installation set up pain.

    If you wanted to eliminate Fast Start up, as a test just to see if it is involved, disable hibernation.

    Command prompt(admin)

    powercfg -h off

    Test for a while to see if behaviour changes. To turn back on powercfg -h on

    Thanks, I'll try that. Can you send me a link to something that explains Win10 Fast Startup, and why turning off hibernation might change it?

    Fast Startup - Turn On or Off in Windows 10

    You will notice in "Tips" for Fast Start hibernation has be be enabled. The command I gave you shuts it off and can be quickly undone. It eliminates hibernation and fast Start up.

    Disabling Hibernation seems to have solved the problem.
