Slow DSL Upload Speeds Problem Over My SBC AT&T Connection

I have had for a while a problem with my upload speed with my AT&T DSL.  I have been a happy customer with SBC for 5 years now and wasn’t about to just change.  I also have DirectTV instead of cable and I’m very content with DirectTV.

My upload speeds for the last 4 months have been shaky and very frustrating.  I was testing it often with speakeasy.com and I knew that the upload was slow and that reported it around 50-70 kpbs on average.  Sometimes it got up to 200 kbps upload speed but I knew that something was wrong.  I have the Pro package at $30 from AT&T which guarantees around 3 mb download and 512 upload speeds.  I’ve been pretty busy working so never really did anything about it.  Tonight I finally looked into it after several support tickets and I believe I solved the problem.  First, let me say that I “think” it’s solved.  We will see over the course of the next week(s) if this remains the case.

What I found out was that I recently upgraded my entire PC.  Well I guess rebuilt it really.  I installed a nice new shiny ASUS P5E motherboard about 4 months ago and I’ve been running Vista 64-bit.  Ever since then I didn’t really think to link anything with ASUS but I think I ended up linking it to its

Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller card.  ASUS boards are so good, I don’t usually second guess it.  But I believe the problem ended up being that in the Ethernet device properties, by default the Speed & Duplex was set to “Auto-Negotiation”:

I changed it to 10 Mbps Full Duplex and I swear that both upload and download speeds have improved a ton:

I now get a solid 2.5 mb on average download (whereas before it ranged and changed intermittently between 1.5 – 2.5 Mbps download and was again around only 70 mbps upload).

I hope this helps someone who has had the same issues with either download or upload speeds.   Check  your Ethernet card, you’d be surprised.

You da man! I was having a horrible problem uploading until I ran across your post and tried the same thing. Bingo! I would never have figured this out myself.
