Hi ashheron&nbsp;
Thanks for posting and welcome back to the community.
Sorry to hear of any service issues. There are no area issues/outages showing.
The Hub is currently showing in Modem Mode. If you can pop it in Router Mode for us to do full checks that would be amazing, also the uptime is over thirty days, so could you please reboot it for us and then re-upload stats?
Best wishes.&nbsp;
