Here's a link how.
I haven't had this problem till like a week or two ago and I reset my router and modem, router twice, then it started working again with no problem. Now I have reseted both my router and modem by completely disconnecting everything connected to them at least three times, made sure my DHCP is enabled through my router(it says through my command prompt that it isn't enabled), and I have flushed my DHCP and I still haven't and it is still being persistent on not working.
I am getting very frustrated by this not working since I have been trying to get it fixed for over 2 hours with no luck. Someone plz help me
