had a zfinity technician rule out the splitter, coax cable, and ethernet cable a possible cause, down to being the modem itself causing the problem. what could be the reason for this failure. also i am hard wired to it (no router in between). could it be a hardware failure on the inside of the pcb board? if so which component that i may de sauder and re sauder.

log into the computer you have connected and see if your actually connected at a gigabit rate. I’ve seen sketchy cables, ports, pc’s that only connect at 10/100mbps and limit speeds.

i tried a few different ethernet cables all give the same results including tried it with wifi as well as one of the efforts

When you check the pc that is direct connected, is it connecting at gigabit speeds? Thats what we need to know. If its only connecting at 10/100mpbs then its pointless to troubleshoot xfinity’s line. But if its connecting at gigabit, its a different story

By check do you mean , check the download speeds on a site like speedtest.net? or is there another way to check

If you’re on windows its usually under your windows network settings for the hardwired device.
settings-->network & ethernet-->Ethernet--->scroll down to link speed
