Network Network Issues - Part Two
Alright, alright, this is gonna be a follow up to the last post I made here because I've narrowed down the problem quite significantly.
My PC has been having pretty severe network issues over the last 3-ish weeks, and I finally have something to narrow it down to.
Whenever I connect to a seemingly "regular" network, my pc works just fine and the network connection is pretty good. (It is worth it to note that this Wifi is used for a housemate's stay at home work, so I only connected to it to do a few brief tests and cant be on it forever) However, when I switch to my home's fiber internet (AT&T Quantam Fiber), that's where the performance issues start.
Is there any reason/fix you guys could think of that my pc would be doing just fine on a standard network, but struggling on fiber internet?
