Probably not what you want to hear but I just bought my own router
You fully replaced their router?
Or you put the hub in modem mode and then just connected it to something that could do DHCP locally?
Put the hub into modem mode and used a unifi router (plus some APs) connected to that.
The hub seemed stable enough in modem mode, was crap when it was asked to do everything.
