Wifi will not turn on and login not connecting

First weird thing is the only r7800 I can find also says AC2600 but on the back of mine is says AC3200. Quite confusing. This morning unprevoked my router which I shelled out $400 dollars for mear months ago stopped broadcasting WIFI. The light is off on the front button and SSID's are gone. So attempting to find out what was going on I typed its default IP 192.168.0.1 and the login and setup pages are inaccesible. Doesn't show a page at all. Does anyone hopfully know what might be wrong? Thanks in advance!

PS. The ethernet ports are still functional but still no setup pages.
