Hi, you can see some of my follow-up posts here:
The issue is pretty much fixed. I do notice little random slow downs here and there but after upgrading and having them install a GPON unit there has definitely been a vast improvement.
Just to be clear, I am on the 150/65 plan now and may downgrade soon as this is definitely more bandwidth than we need at my residence but they had to switch me to GPON and onto a new splitter in the neighborhood so it pointed to an oversaturation issue on the previous splitter and BPON.
If the issue comes back after I downgrade to the 75/35 I was on previously I'll update here.
