Welcome to this user forum.
You need to prove whether ita a router issue or a network issue, by trying it with a BT Home hub.
Funnily enough, I’ve also been suffering a lot of IPC6023 errors recently after year(s) of no issue ... no difference in my kit and I have a very reliable 80/20 Infinity 2 service with no resync issues and barely any errors.
I find the IPC6023 error is almost exclusively on HD channels and happens after about 30 to 40 minutes viewing. Seems to improve after rebooting the YV box. Doesn’t appear to affect recordings (ie hour+ long recordings complete without problem).
I am wondering if it’s another exchange related issue or YV box problem (again). Personally I can’t stomach the thought of contacting BT about the issue by phone as I know how it will play out; lots of time wasted to no effect.
Sorry to hear you are having problems with the BT TV service.
If you are able to send me your landline number or account number via a private message I'm happy to take a look for you.
@Wrights83 you mentioned your friend also has a problem with IPC6023, if you could send me their landline or get them to send me their details as well I can look into their problem as well. And if you are able to check using a BT hub as well just for comparison and let me know if the issue is the same then that would be extremely helpful as well.
Thank you all for your help. Using the smart hub has fixed the problem. So far now I’m happy to use the smart hub even though it says my speed has dropped at least 5MB. My landline is **Edited** if you want to test why the speed has dropped compared to when I was using a Netgear router.
