Hope it works!
Try direct connecting it (without the tv) to test it.
If you still have issues, look back further down the line.
If you don't find any other issues, the ISP will need to check the line.
Again, good luck. It can be frustrating chasing line errors.

Replaced the splitter and the cable from splitter to modem with best I could find on Amazon. Tried without TV.
The Cable Connection doesn't have that many uncorrectables. But unfortunately the speed is still 30 Mbps.
New logs are attached.
It looks like I am at the end of the line :-) and will have to call ISP (Optimum).
Is is possible the modem has developed fault? Would it be worth replacing it? I am not very confident about ISP technicians, it is a hit or miss.

It could be a modem failure. Its always a chance.
something I've had to do before was to rent a modem from an ISP to get them to prove it was either a line or modem issue. (was the line). Cost me $10 to rent for a month and then I returned it.
Sometimes thats an option you can use. And if it fixes the problem, then you know its the modem. Maybe you're still within warranty?
To check, click on "mynetgear" at the top. register an account and the device. From there you an check warranty - zunkaSep 23, 2021Guide
My warranty has expired. It has been slightly over an year since I purchased. Let me try the option you suggested. Hopefully if the technician brings a modem with him/her that we could try out, there may not even be a need to rent.
Thank you.
