I can't connect to a particular network

srsly · 20 May 2016

This has been driving me mad for days, I cannot connect to one particular network in Win10 as it always shows "no internet access" and diagnose tells me that "one or more network protocols is missing" and other times it tells me there was a problem with the access point and it was fixed and restarted, but in reality nothing is fixed, it's still showing no internet access. My trick is to connect to the wifi on my tab and connect it to my Win10 laptop through usb tethering, but this is really cumbersome.

Wifi works flawlessly on ubuntu (dual boot).

UPDATE 1: I also can't connect to the default gateway, when I try to access the router page firefox said the connection has timed out, ditto for chrome, pinging the default gateway also returns "request timed out".

UPDATE 2: I've updated the wireless driver from atheros and restarted but it's still not working

UPDATE 3: flushed dns and resetted winsock, restarted, error still won't budge, does anyone know what steps can I take to troubleshoot if I can't ping even the default gateway?

UPDATE 4: For whatever reason I still can't connect to the wifi broadcasted by the router itself but got a repeater and everything works fine so that saves me from headaches for now.

These symptoms suggest that you have a not-perfect Microsoft driver for your Wi-Fi installed. You can use a utility such as Aida64 to identify your Wi-Fi card and then find official drivers which should work better.

The simplest method is to visit your notebook manufacturer's support site and download the latest Wi-Fi driver. If there is no Windows 10 driver, try that for Windows 8 or 7. Once you download it, right-click and Run as Administrator. It should install OK and your Wi-Fi should work as expected.

There is a chance that Windows Update finds a "newer" driver and replaces your official working driver with the "newer" not-working Microsoft driver. To prevent it, use the show/hide tool to find and hide (disable) the respective update as described in this tutorial.

In the unlikely case that the driver from manufacturer's site doesn't work as epxected, you must use Aida64 to identify the hardware of your Wi-Fi card and then google it to find drivers.

Not connecting on one particular network means that there is an issue with that network. Have you asked others if they are having the same problem?

The Missing Protocol is caused by Microsoft removing Guest access and locking down the OS to protect it from Malware.

Thanks for the suggestion I'll try this later

As I said, no one else is experiencing issues on the network, nor my other devices and OS, so I'm 100% sure somewhere in my OS something isn't configured right I just haven't figured out what it is.

Try flushing the Winsock and Dns. Farbar's Minitoolbox comes in handy for this.
