Hi Fluxorion,
Thank you for all steps that you have tried so far. I suggest you to connect the laptop to the router using a wired connection and let me know if the same issue occurs. Check if this issue occurs in “Safe Mode with Networking” and the make and model of the router. I have added you as a friend. Please accept my friend request by clicking on my name ‘DELL-Rajath N’ highlighted in blue and then click on “Friends” tab at the top and then click on “Request to Review” and finally click on “Accept” button.
I am sending you a private message as well. Click on “Inbox” to respond to the message and provide the system’s Service Tag and contact details (including the name on the account) so I may access your system records and check for further course of action. You could also click on Start Conversation to send a private message. Please let me know if this helps.
