:About two weeks ago I had my DSL which I have been using for 5 months go from a steady download speed of ~3000kbps to a speed no more than 640kbps.
When I run speed tests on my line it continually gives results of 1300kbps which is not even close to what I'm actually seeing when I'm pulling files down. When I run wireshark to check my packets, I see a packet lost every 1-8 seconds depending on bandwidth I'm using. Each packet loss leads to the inevitable out of order packets which cause further problems. Simply browsing webpages leads to visible pauses in pages loading.
I have since tried using a old DSL modem I found which did not change anything. I've called AT&T and they've tested the line but since I still have a connection they have not done anything on their end. They scheduled a van but the earliest appointment they had was for two weeks from now.
I stumped at what to do now. I've told AT&T that I'm experiencing huge packet loss but the reps on the phone ignore me. At the same time its odd that if my packet loss is really the cause that the line speed averages to a constant 640kbps download. Since I have tried replacing all the hardware on my end is there a way to convince the AT&T technical support that its on their end?
