did you ever find a solution for this? i have same issue on a new lenovo - ITS is blaming norton, but that was never an issue on my old hp which ran windows vista.
Just purchased an Asus K532-BBR9 laptop. Everything works fine, except on college campus the internet is very slow, and disconnects every few minutes.
My fellow students laptops do not seem to have this problem.
I figured it may be a driver issue, so I am trying to update everything.
Under Network Adapters in Device Manager. The Microsoft Virtual WiFI Miniport Adapter is not up to date when I do a driver update scan.
Then it says "Windows can't verify the publisher of this driver software.." with options to install anyways.
I tried to manually find the driver online to verify if it is safe but could not.
All advice is welcome!
