Hourly total blackouts

Hi, I have been affected by hourly total blackouts (No Internet, No TV) much like other posts I've seen here, which are beginning to affect my productivity.

Daily drops around about the 12.30pm mark for the first time, I have to go and reboot the Hub 3, takes it about 15min+ to recover connections. This repeats about hourly until 17.30pm ish for what is normally the last one for the day.

This is starting to become increasingly frustrating and unsustainable, right now I'm mananing, but if this keeps up, the only things getting dropped are going to be the services themselves as my contract is past the minimum term. Has gotten to the point where I most definitely will use my 4g connection for a job interview. 

All connections are secure.

Hub 3 rebooted and unplugged from mains for a few minutes - Issues still persist.

Hub factory reset - Settings page seems to have updated, but issues still persist. 

Can I please have some directions on how to get to the tech stuff on the Settings page, so I can post it in here? Thanks in advance for any help.

Re: Hourly total blackouts

Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs as text. The forum software will remove the MAC addresses for you (you may need to click the 'post' button again).

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Hourly total blackouts

I have also created the monitor, I'll add it once it gathers any meaningful data. Meanwhile I'll just hope it doesn't go down much. Thanks again

Re: Hourly total blackouts

Can you post up the data from the upstream and downstream tabs in the same way?

Re: Hourly total blackouts

Power levels look within spec but the T3 timeouts are a concern as the Hub looks to have been rebooted today!

When these T3s happen - it affects the downstream channels locking on and the modem has to renegotiate channels with the CMTS and it looks like a reboot - whereas it is a re-negotiation (which takes as long as a reboot and looks like one - So probably may as well be one!)

Interestingly enough, these timeouts are only between 12.30pm and 17.30, I don't remember it happening outside of that timeframe

Hi Joesmael,

I am sorry to hear you keep having dropouts I have checked your hub stats and you need a technician, I will pop you a PM and we can go from there, just keep an eye out for the purple envelope
