Question Ethernet Upload Speed <0.1 Mbps

Aug 9, 2022
Just got back from abroad and been having this issue. My ISP is Verizon and I regularly get download speeds of >800Mbps and used to get upload speeds well over 100Mbps. Upon returning after 2 months of being unplugged from the wall, my desktop (an iBUYPOWER PC, specs listed below) was getting the same download speed via ethernet, but upload speeds of less than 0.1 Mbps. I updated drivers, replaced the cable, verified that a wireless connection by a USB adapter worked fine (albeit slower, because ethernet>WiFi), verified that the cable was functioning properly by plugging in my laptop and getting ~800 Mbps down / ~200 Mbps down, and found some old threads on Microsoft from 2014 that suggested enabling / disabling IPv4 / IPv6 LSO settings on the controller - no luck. I'm well beyond my technical expertise at this point and am completely lost beyond just buying a USB-Ethernet adapter and trying that. Thanks for the help in advance.
