Can't connect to this network on Windows 8

[Azmir]

Hello everyone,,
I was able to connect to my wifi without problems until about a month ago. After I changed my router settings so that one had to go through "registration" (searching for wireless devices), it worked for about a week and then randomly stopped. I changed it back but to no avail. I've reset the router, I've reset my network profile, changed the channel, change the password (WPA2-PSK) but still I cannot connect. I don't know what's wrong. I have a Lenovo Y510P; all my wifi drivers are updated https://mobdro.bio/ https://webhost.kim/bluehost/ https://kodi.bio/. My router is a Technicolor Gateway TG789vn v3, all other devices work fine. I've deleted my network profiles and reinstalled my network adapated.

Help would be very appreciated..

In an elevated command prompt

• Type netsh wlan show profile
• Make note of your wireless profile (SSID)
• Type netsh wlan delete profile name="ProfileName" i=*
