Welcome to the forums, I'm sorry to see you have been having trouble with your connection.
I have taken a look at the connection and everything seems to be ok from this side.
How are your speeds on a wired connection? Pop the hub into modem only mode and the computer into safe mode with networking and let us know if it makes a difference as it will help us to rule some things out.
I am assuming that the Webmail issue you are referring to is F004841712 which is where people are having trouble signing in. We are still working on this but we don't have a resolve date currently. Apologies for the delay.
