Welcome to the Community!
really sorry to hear you're having trouble with your new install.
I've run some diagnostics on your equipment and everything is looking great at the moment. your levels are all as they should be and there are no issues with the network in your area.
Are you connecting wired or wirelessly?
I'd like you to try a speed test with the hub in Modem Mode to see what results we get.
