Recently, I have been getting slow upload speeds from Verizon Fios. I had a intel NIC card I225-V, and then I replaced it with a Realtek RTL8215 and it was normal for a small period of time, then went back to the normal 1-10 mbps upload speed. I have the gigabit plan, and have tried everything including turning off IPV6 Checksum Offload, and other methods as well. Unfortunately, the issue arose again, and I don't know how to fix it. This is definitely an issue on Verizon's part because I have tested multiple devices, ethernet cables, etc.. I was curious if having my own router would fix these issues.
