Connected to Network but "Secured, no internet"

I was having some network problems and in the course of fixing them I uninstalled the network driver for my TP-Link AC600 Archer T2UH USB network card. This card has been working without a problem for months on 2.4 and 5Ghz channels and at high speeds > 150Mbps.
When I attempted to reinstall the drivers, I can get connected to the WiFi but I get the Windows 10 message "Secured, no internet
I have tried numerous drivers and I have now tried to connect using two separate NIC cards. (I had an old 802.11n usb adapter) as well as a 5Ghz wireless bridge that I used to use that connects to the PC via ethernet. All of these have connected to the network, but I get the same "Secured, no internet" message.

The only thing I can think of at this point is that I've somehow screwed up the adapter. I've looked at that ipv4 settings are they are all set to "Obtain an ip address automatically" and do not have a DNS name specified. I have attempted all the windows repair options as well and they return telling me their may be something wrong with the driver or the adapter. I'm at wits end. Any suggestions would be appreciated.

Hi,
Welcome to the forums, if you have any third party AV programs, disable or uninstall it, go to device manager, right click Wi-Fi adapter, Properties and uninstall the driver. Reboot your PC/Laptop and let Windows install the driver, go to IPV4 as you have done before, click the radio button "Use the following DNS addresses...." and enter Open DNS address(in the snip) or google dns address.

This is happening to me too! I'll keep it short, I typed this out once already and lost it when the disconnect happened.

I am using this: TP-LINK TL-WN821N 300Mbps Wireless N USB Adapter: Amazon.co.uk: Computers Accessories on a desktop PC.

I am using Google DNS:


I have lowered my MSU packet size. I have switched off windows' ability to auto-power this device.

I think this happens more often with qBittorrent open?

-Edit-
I hit save so I wouldn't lose what I typed again. I have lowered my max connections all the way down to 50 in qBittorrent. My router is not doing anything wrong. This never happened to me via Ethernet but I am now in a different room in the house so wireless is more convenient.

I have tried drivers and all sorts. I can't stop this happening.

Thanks for the response. I did exactly as you suggested. Unfortunately it did not work.

I have tried to connect to the wifi broadcast by my iPhone. That did not work either. Same error. "No Internet, secured."

Hi,
Go to Device manager, expand network adapters, right click Wi-Fi, can you post what you have for HT mode in Advanced tab, does it look like mine or you have 20MHz, 20/40 MHz etc.

I don't have an HT Mode. Here is what my adapters and advanced tab look like:

If the OP is seeing the same thing on his iPhone as his PC then it is more likely a router issue. OP: Have you rebooted your router?

What I'm saying is my iPhone can connect to WiFi without a problem, but when I turn my iPhone onto LTE and set up tethering, my PC still cannot connect to the internet via the iPhone tethering. All other devices on my network are doing just fine.

Hello,

Okay guys here I find solution which worked for me after trying reg delete, driver uninstall and more. Network settings > change adapter options > right click Wi-Fi > uncheck antivirus(comodo for me) internet security firewall driver.
