So around a month ago I was having internet issues and was getting random packet loss when gaming on my PC. I tested my connection and was getting around 15mbs down and 15mbs up (my normal speeds are (70 down and 15-20 up). After a couple of days, the packet loss stopped. However, when I tested my internet connection after and ever since my download speed is between 35-50 and upload is 15-20. I have tested my connection on my phone and the results I get are as expected 70 down 15-20 up and 10 ping. When testing on my PC (via ethernet cable) My ping and upload both seem to be what they should, however, my download speed is sometimes half of what it is on my phone. It is possible that the issue started before the period of packet loss as I had not tested my connection for a while before that. I have a TP-Link powerline adapter which I have used for years without issue. I have reset my router 1000 times, tried a new ethernet cable and wiped my pc, but neither resolved the issue.
