x6s EX8000 Range extender issue
I am using a Netgear R9000 router, and have been using a Nertgear EX8000 range extender for more than a year. Recently, the internet download speed of devices attacehed to the extender dropped (I have 200Mbps xfinity). I rebooted the modem (a netgear CM600), the router and then the range extender. I tried logging in to the range extender, but when I do, the staus page is completely blank save for the netgear banner at the top. I have tried different browsers, different computers, both wired directly to the extender or through wifi. I did a factory reset of the extender, and went through the process of setting it up on my network again; the problem persists. I have done all that I can think of; I would appreciate any input that anyone may have that will help me fix this problem. I have attached a screenshot of what It looks like. I am running Windows 10 Professional with all updates being current.
