Bandwith speed issue
So I have been doing a Ookla speedtest at various times of the day over the last week. My download speeds have been about 27-30 mbs and upload speeds of 60+ mbs. Months ago my download speeds were easily in the 70+ mb range, often higher than that. By the way, I am on the 500 mb plan. I have tried to figure it out with no luck. Checked my router to see if anything has changed. Nothing. Disconnected my VPN, hardly made a difference. Checked it on WIFI on my laptop, then on my desktop with a wired conection. No change, download speeds about the same. Basically nothing has changed that should account for this difference. Thinking I may be throttled by Cox, I went to my data usage in my account, where the "other" category accounted for 41% with a week and a half to go, but last cycle it was 14%??? Fortunately I am not having any issues viewing, or doing what I want on the internet, but I am concerned in the fact I am not getting NEAR what I am paying for. This is also the first time I have ever seen my download speeds being consistently beaten by a good bit by the upload speeds. I do not know when this started, I do not routinely check my speeds on a regular basis. Any thoughts?
