I don't remember the webpage that I found it on, but here's the solution I came up with. I created a batch file (.bat) that has the following in it:
Code:
netsh wlan set hostednetwork mode=allow ssid=<WhateverSSIDYouWant> key=<IUseMyPhoneNumber>
netsh wlan start hostednetwork
I saved that to the desktop as StartNetworkSharing.bat. Make sure that if you are using notepad to create it that it doesn't have .txt after the .bat. You'll have to turn off the checkbox in Windows Explorer that says "Hide extensions for known file types".
Now right-click that file, and run as administrator. You'll see a command window open and then close really quick. It might be a good idea to copy/paste those lines into a command window (started as administrator by hitting CTRL-X then Command Prompt (Admin)) the first time, that way if there's an error you'll see it.
Now go into Network and Sharing Center (right click the network icon in the System Tray), and click Change adapter settings (left side). You should now see the new connection that you just created. Right click on the network connection that is actually connected to your WiFi, probably the one with Marvell in it, choose properties, and click the sharing tab. Click the checkbox to allow other network users to connect, and under the drop-down list, choose the new connection you just created, to share the current connection with that connection.
Once you do this, I have found on my wife's computer that she has to click the batch file every time to start the connection, but doesn't have to go into the sharing center for that setting. So just a couple clicks - making sure to right click it and run as administrator, and her connection is shared.
The caveat that I have to add is that this procedure does not work on my SP3. It works on my wife's Lenovo Yoga 11S. But I believe that the problem with my PC is that I have Hyper-V installed, which also seems to cause other WiFi problems (like when my PC wakes from sleep, I have to turn WiFi off and back on or it will give me a limited connection). It is possible that this doesn't work on any SP3, but I have no way of telling. Hopefully it is just because of my Hyper-V installation.
