I don't know why my TP Link Archer C6  Router Reboots automatically after some hrs but it's more than 10 hrs. My pc connected to it and I am attending the online class automatically router reboots. And one more thing sometimes wds stop working automatically and in front of wds status it shows as Assoc. Sometimes it fixed by rebooting or power off and I don't know the proper solution of this problem.

Please no one suggest me any cable option. I can only connect this router to main router wirelessly only
