I have COVAD DSL and have 1.5/384 DSL. I noticed over the last few weeks my download stream has been low, around 950 - 1000 on downloads. I had previously been around 1.3 on my tests.

So I logged into my router and I see it was syncing at 928/384... so I went to broadband reports and made a post and one of the guys suggested I was in "Safe" mode due to noise on my line perhaps. So I called COVAD and he was correct, although they couldn't figure out why I was put in "safe" mode.

I just checked my router and my noise margin actually increased, which is a good thing, and my syncing is now back at 1.5/384 and I ran tests at 3 different places and also my SiMeter and I came out at 1.3/318 - I can live with that.
