Keeping getting black page saying page can't load
Ever since we bought this router some pages will not load on the internet. First, we get a black page saying the page cannot load, and then it refreshes itself and loads the page. We didn't have this problem before we bought this router. We have talked to our provider, Spectrum, and we upgraded to a newer modem but they told us there's nothing wrong with the modem. They also checked the speed and it is also okay.
I set up the router under the Basic setup. We are all wireless. We are also having the same problem with our cell phones. Sometimes we have to just turn off the wi-fi on our cell phone for the page to load using the cellular data. The router is in the same location as our previous router.
Is there a certain setting that should be used in the configuration of the router? Does it have anything to do with it being a Mesh router and we don't have any Mesh products to go with the router? We've had it for about two months now and really frustrated.
