I upgraded from a 5 mbps down and 0.4 mbps up plan to a 10 mbps down and 0.8 mbps up plan about 5 days ago. Almost instantly after upgrading, my download speed improved, but my upload speed is at around 0.2 mbps. After talking with my ISP, they said the change should be instant. I already rebooted my router and modem multiple times and I am connected via Ethernet. What could be causing the problem? Any help would be appreciated!
