Extremely odd issue

Car712 · January 20, 2019

So lately I have been having about the oddest issue with my internet, with multiple computers and connections. Downloads from any particular site/application will usually be around 1.4-1.5MBPS+ (since my internet speed is usually 15MBPS), anyways what will happen is the downloads usually start around the normal 'fast' rate, and will have sudden dips lasting anywhere from a few seconds to 10 minutes. Sometimes they will dip down to 500KBPS, and then go back up, sometimes it even goes down to 20KBPS for a minute or more (want to note that other internet functions work fine and fast when the download speed goes down to this). I have the same issue over Ethernet, Wifi, anything. Ive rebooted the router many times, and cant seem to get to the source of the issue. I also want to note that the issue dosent always happen, sometimes downloads will stay around the 1-1.5MBPS range and be fine. But when the dips do happen its extremely annoying as I have no clue as to whats causing it, as nothing is using that much bandwidth for 10-20 seconds when it happens.

My prime suspect at the moment is that AT&T is throttling my speeds, as I have downloaded pretty much my entire steam library this past month onto my build. However, from what I have seen I dont have a 'limit', and I usually use nowhere near the 'max' usage on our bill, which if I am remembering correctly is 1TB.

My router is a AT&T router/modem combo, my connection is over normal DSL (phone line).

Could be AT&T is simply throttling your connection.

Alternately, your copper line could be corroded...

I think 1Tb is for Uverse while there was a lower limit for aDSL. If you hit that data limit I though AT&T just charges you more money rather than throttle. Like @Radium_Angel suggested, you could have a line issue, hopefully for your sake I hope not. It could also be an issue with congestion on the network its self.
