@Mjconnolly Thanks for posting, I'm sorry the replacement Hub has not made a difference. I can see @PaddyB has made arrangements to follow up with you tomorrow and I'll make sure to let him know that you've posted.
Thank you for taking my call today. I'm happy to hear that your connection is behaving itself following on from the last engineers visit. I've run an few checks on your line and your connection is looking pretty good. Your sync speed has increased to 79.9 Mbps but the main thing is the stability has improved.
Please keep an eye on your connection over the next few days, If you notice the connection becoming unstable again, please get back to me.
