Minimum Elite Upload Speed?

Prior to my "repair" on Saturday I was getting anywhere from 0.5-0.6 Mbps upload, now I'm only getting 0.3Mps! My upload sync is 600 something.

They used to publish the upload speed, seems I can't find it anymore.
Anyone know what it is?

I also lost about 1Mbps download after the "repair" .

Elite should sync 6016/768 down/up. What are your line stats?

I'm at work but as I remember approx. 5500/600.
Prior to the repair I know I was able to get 6012 up and 600 down.

The phone tech said they guarantee 75% down but nothing about up.
I tried different computers and speed sites plus plugged directly into the NVG510.
I didn't disconnect all the others though, but I don't think(hope) anything is being streamed out using 1/2 my bandwidth.

Thanks!

I am including a picture of my current stats. These are the ones of most interest, though there are some differences between ADSL and ADSL2+.

Line statistics

At the top is the actual sync rate of the modem with the DSLAM. In the world of AT&T ADSL, there are fixed tiers with specific capped rates. The AT&T Elite tier should show exactly 6016 down and 678 up. (By contrast, my ISP does not have tiers, and allows the modem and DSLAM to freely seek the most stable sync rate; up to the maximum ADSL2+ sync rate.)

The next lines show the Signal-to-Noise margin and attenuation. In the world of AT&T ADSL, my 5.7 dB SNR would be marginal, and I would have difficulty holding sync at the tier rate. The attenuation is a measure of line loss due to distance; higher indicates a longer loop.

The final lines show the connection type and data path. In the world of AT&T ADSL, you would see G.DMT for ADSL (though one version of their SS4100 modem firmware erroneously displays "ANSI" instead of "G.DMT". My G.DMT2+ refers to ADSL2+, which is what my ISP provides.

The "Interleaved" refers to an error correction protocol. With my lower SNR, this compensates for data loss. When I had AT&T DSL Pro, my SNR was a much healthier 11.0 dB, and I had a "Fastpath". The difference between Fastpath and Interleaved is a few ms of latency; I can live with the higher Interleaved latency for the sake of the higher speed. In the world of AT&T ADSL, if you are on Fastpath, first hop latency can be as low as 10 ms, where my Interleaved adds ~15 ms to my first hop latency.

Thanks for the comprehensive post!

Sorry about the lack of formatting but here's my results just after resetting the modem:

Downstream Sync Rate (kbps) 5206
Upstream Sync Rate (kbps) 598
Modulation ADSL2+
Data Path Interleaved

Downstream Upstream
SN Margin (dB) 6.9 3.6
Line Attenuation (dB) 35.0 20.8
Output Power(dBm) 19.1 12.4
Errored Seconds 180 729
Loss of Signal 0 0
Loss of Frame 0 0
FEC Errors 7314 7657
CRC Errors 200 789

Using the at&t speed test I got 5.00/0.35 down/up.

Only the operating computer was plugged into the modem, wireless off.

Just 10 days ago I took a snapshot previous results, here they are:

Downstream Sync Rate (kbps) 6012
Upstream Sync Rate (kbps) 766
Modulation ADSL2+
Data Path Interleaved

Downstream Upstream
SN Margin (dB) 9.1 10.5
Line Attenuation (dB) 38.5 23
Output Power(dBm) 18.2 12.1
Errored Seconds 5 0
Loss of Signal 0 0
Loss of Frame 0 0
FEC Errors 1773 0
CRC Errors 162 0

Back then I was getting 5.7 down and I'm thinking the up was in the .6 range.

Thanks Again!

Just got AT&T Direct on the case, now I'll get some answers!
