Re: [speed/latency] Very slow upload speed With 3000/768 DSL you should be seen speed test results of about 2800/700 kbps to nearby test servers.
First step it to check modem stats to see of it is able to sync at correct speed. Verizon sets sync rate higher then advertised to compensate for overhead. Sync rate for your plan should be 3360/860. Download and upload margin should be 10 dB or better. Between 10 and 6 dB modem is vulnerable to interference. Below 6 is will not be able to maintain synchronization.
If you are not sure how to interpret stats post them here.
Hopefully when running performance test you are using wired Ethernet to eliminate issues with WiFi. Also be sure none of the other PCs on your LAN or the test PC is running applications that access the Internet during the speed test.

1 edit | Thanks for the info. Yes, I'm testing on the wired connection, and with the other PCs inactive. Here are the stats from my modem:
Transceiver Revision: 4.3.0.1
Vendor ID Code: 4
Line Mode: G.DMT Mode
Data Path: Interleaved
Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 1792 160
Margin (dB) 17.0 31.0
Line Attenuation (dB) 35.0 21.0
Transmit Power (dBm) 6.3 11.3
I assume the "DSL speed" here is the sync rate you are referring to. If that's the case , it appears not to be syncing at the correct speed. What are the possible causes, based on the other stats? |

| After staying up late last night reading other posts and looking at the stats others have posted, it seems that my margin and attenuation stats really aren't bad, and that I should be able to achieve much better sync speeds and throughput than what I have been getting.
That just leads me back to my original thought, which is that Verizon has my account provisioned incorrectly. Should I call Verizon at this point, or is there further troubleshooting I can do myself? |
