Hi,

First thing to do is to make sure you're running at least Version 18.11.0, A00 of the Intel 7260 WiFi Driver.  That is the latest version of the Intel Wifi drivers that we currently have on our support pages.

If that doesn't help it sounds like it's a configuration / power issue.  Windows handles power for components slightly differently during a cold boot up as opposed to a restart.   We can try the following steps to see if that helps.  

1. In the Search box, type Device Manager.
2. Touch or click Device Manager (Control Panel).
3. In the Device Manager window, click the arrow sign next to Network Adapters.
4. Double-tap or double-click the Intel PRO Wireless.
5. Click the Advanced tab.
6. In the Property: box, click Roaming Aggressiveness and select 2. Medium-Low from the drop-down menu.
7. In the Property: box, click lick Throughput Enhancement and click to select Enable: from the drop-down menu.
8. In the Property: box, click lick Transmit Power and click to select 5. Highest from the drop-down menu.
9. Click OK.

See if changing the power settings above help at all.  Please let us know so others that may have the same issue can find the resolution (assuming this resolves the problem that is).

I will give the above suggestions a try, thanks for the help.
