Welcome to the forums, I'm sorry to see you have been having trouble with your connection. I have taken a look and everything seems to be ok from this side.
Are you having trouble with a wired or a wireless connection? If wireless try wired. Pop the hub into modem only mode and the computer into safe mode with networking and let me know if it makes a difference.
