About a week ago i started getting drastic speed swings, high packet loss, fluctuating latency, and lag which makes games unplayable online. I made sure all my software/firmware was up to date, i restarted router and modem multiple times, i contacted xfinity for help and was told it wasn't "their end." I bought a brand new modem and installed it with no change in the problem. When running internet speed tests my speed drasticaly fluctuates from 119mbps to sometimes less than 1mbps. Yesterday when I ran a speed test my upload speed was faster than my download speed, which I have never seen before. I ran virus scans for malware ETC and found nothing.
I am using an ASUS AC5300 tri band router with an ARRIS SB8200 modem and I am on a wifi network. Again, this problem started within the last week, nothing on my end had changed.
