I just bougtht an AX1500 Wi-fi Range Extender and installed it. While the speed says it's fine, it will only connect to Gmail, Youtube, Google search regardless of the browser. It's also not connecting to apps like Signal. When I connect my laptop back to my router (different brand), I don't have the same problem and it can access all pages. I've seen mixed answers on how to fix this problem with routers, but not with a wifi extender. Thanks!
