I need some help. I have been reading through the threads on this board and I still cannot find a solution to my issue. Like many others, I have noticed a pretty dramatic swing in the download speeds of my Uverse internet. It has been going on for a while, but it finally got so bad that it was affecting my Uverse TV, so I called in Tech support. I had a tech visit yesterday and he said that there was a lot of issues with my system. He replaced the old RG with a new 3801HGV and he replaced the old DVR with the newest version. He also ran new wire from the interface outside of the house into the RG. Just before leaving (at approximately 2:30pm) we ran a speed test and I was getting 16 Mbps+ down. I used Speedtest.net and att.com/speedtest. Later that evening as I was streaming from Cbs.com, the video started breaking up. I reran the speed test and the download speed was around 2.5Mbps. I chatted with tech support, and they said the line was clear, but scheduled a tech support visit for tonight.
I get up at 6:30 am today and run speed test. I was still getting around 2.5Mbps. I reset the RG and rebooted the computer. I was able to get one speed test at 16Mbps+, but the very next test was back down around 2.5Mbps. I went to work and came home at 3:45 pm. I ran speedtest and was getting 16Mbps+ That continued for the rest of the afternoon and into the evening. The tech called at about 6:00 pm to say that he was in route and I was still getting 16Mbps+ down, so I told him he didn't need to come. I should have had him come. At about 7:00 pm, My speed started dropping, and now when I run speedtest I'm getting around 2.0Mbps. I checked the RG and I was not getting many errors, or other issues that I could see. I installed UV realtime so that I could post screen caps of the bit loading. I don't see anything, but perhaps you will.
Due to the timing and the large fluctuations, I wonder if it is due to Weather (cold), Time of Day, Daylight or some other environmental factor.
I have been a Uverse subscriber since 2009, and this is my first real issue, so I am really puzzled. Any help would be appreciated.

Your error counts and bitloading graph look fine.
I'm wondering about competition for the connection. The most obvious is downstream use of HD streams, as each one of those uses almost 6 Mbps from your 32 Mbps total available. However, you should have a minimum of 8 Mbps, and you're measuring less than that.
So, the remaining questions are:
1) Do you use anything that uses a lot of upstream bandwidth, such as online backup, bitTorrent, other P2P software?
2) Are you sure no other computer is consuming bandwidth while you're doing the speed test?
3) Can you screenshot the Usage tab from UVrealtime just before, and just after a speed test?

Thanks for following this thread with me. You raise some good points. I have thought about them, but I had mostly dismissed them. Since your post, I have dug deeper into the details to see if they could be the source of my issues. After digging deeper, I think they may play a role, but are not the only issue.
1. I use Crash plan for online backup and I do have 3 computers configured to use it. I have limited the computers to use 300Kbps of bandwidth only. However, If all 3 are backing up at the same time, that could consume a Full Mbps. I do not use any P2P software, but I did scan all of my machines to see if any trojans or botware had gotten by the anti-virus. I found nothing.
2. I am reasonably certain that no other machines are using bandwidth. When I experience slow internet, I have them all shutdown and run speedtest and still get the same result.
3. Here are some updated Screen shots from UVrealtime. I don't know how to force a refresh in UVrealtime to get a usage report from just before and just after a speed test. Everytime I try, I see no change in the screen.
Thanks in advance for any help you can provide.
