Hi Jin,
I came to this forum looking for a problem like this. I am in Oceanside, have the 500/10 plan, and I am recently noticing massive slowdown to upload any decent size file (100MB+) to any number of places. I just started noticing it Friday March 18, but it could have started sooner. How slow? Well, Friday I was getting around 1.8 Mbps, but today less than 300 kbps. Like you, the speed tests look fine, and I even tried selecting servers outside of COX. It totally smells like a route problem, but I have tested uploads to Amazon S3, GitHub, YouTube. Google Drive, and Microsoft OneDrive. All behave in a similar manner., which is very strange and suspicious. If there is a route problem then I believe it is specific to COX. I have only been using COX for 11 months, and previously used Comcast in the SF Bay Area without this problem.
P.S. I have never exceeded my 1.2 TB data limit and currently have used 46% in the current cycle which ends in a few days.
Hello ddennedy and Jin,
I also came to this forum looking for answers. I was recently pushed off of my old plan of 300dl/30ul mbps speeds and was offered the Gigablast plan for 2 yrs at a lower price. I had to buy a new modem bc my old one was only Docsis 3.0. So I bought an Arris SB8200, which is compatible with Gigablast. The first week or two I was getting normal speeds on my Xbox Series X which is hardwired to my router. Normal speeds were around 900 mbps down, and uploads varied but could reach into the 20 mbps range. However over the last couple of days my upload speeds wont go above 2 mbps and hover around 1 or even less that one which is not good for staying connected.
Anybody have any ideas how I can get the speeds I am paying for? I have tried multiple things to no avail.
