So I got fiber installed yesterday and it works fine except for one thing. When using WiFi I get the full speed of 350 mbps. But when I connect my pc to my router with a pan cable(cat6) it locks at 100. I have no idea what to do I called my isp so many times and they’ve been of no help.


Yeah i fixed the issue. The store i bought my ethernet cable from scammed me saying the cable was cat 6 while it wasnt. i tried the cable that came with the router and it worked fine and i got 400mbps.
It may have just been a defective or improperly made cable. Even cat 5 can support gigabit links if manufactured properly.
What brand was the store cable? How long? Can you share pictures of it, especially of the plugs showing the wired inside?
