    I just got a Surface Pro 3. While I do like it, I notice that every once in a while after hibernating/sleeping for a few hours, I will turn the surface back on and have no wireless card at all. This isn't the problem where it can't connect to wireless networks; it can't see that it even has a wireless card at all. I went to device manager and there was an indicator that there was a problem with the device, but enabling / disabling it didn't help. Unfortunately the only way I found to fix it is to restart the system. Has anyone else run into this problem or have any advice on how to remedy it?

    Thanks,
    Evan

    I also STILL have issues occasionally after sleep even though there were updates to address this very issue.

    I haven't encountered this specifically yet. Mine won't reconnect to my AC router when the device wakes up from hibernate. I have to manually disable and re-enable the adapter to reconnect. Very annoying indeed.

    Thanks for the tip. Any impact on WIFI performance with the July 2014 drivers?

    This could be an issue with the device, the device driver, or the USB bus that connects the Marvell chip chip to the system. Try a sleep / resume cycle to see if that fixes it.

    I reinstalled the WIFI driver. Just when I thought the reconnect problem was resolved, the issue reoccurred this morning. When the SP3 woke up from hibernate, WIFI was stuck with limited connectivity. I had to toggle the WIFI adapter off and on to fix it. Quite annoying. I didn't have this issue with the SP1.

    This time I uninstalled, deleted the driver, and reinstalled using the July 2014 driver pack. Let's see if the situation improves.

    Speculating: This is probably related to the connected standby mode and dynamically powering off the WiFi to save power. its probably not always waking up properly. Disable and reenable would make a lot of sense in that situation. Likely the target of a future update ... Reinstalling the driver would probably not have any lasting effect.
