A question about upload speed.


[link to this post]
 
Technically speaking, why would an upload speed drop from 17-7 Mbps, yet my download speed only from 60-55 Mbps.

This is related to this thread but I thought I should ask as new thread.

Best Regards

Line fault or a lot of power cuts banding the DLM.

I've seen my upload drop from around 11 to 5, but my download actually increased, after a few days it returned to normal.

Perhaps it is related to the teed line...

I was trying to figure out why that would have any effect at all, and the best answer I could come up with was multipath fading... which is usually a mobile problem.

Perhaps, having 2 copper paths of slightly different length, the signal is following both, and getting a tiny delay in one leg, enough to cause cancellation issues at certain frequencies.

Perhaps, then, the upstream frequencies are more susceptible, or perhaps there's a difference in power that helps cause it.

Have you got before/after graphs of SNR, Hlog, QLN, Bitloading etc?

Bridge tap possibly, and the general fannying around with all the stuff in the cabs is surely bound to have an effect on the signal itself

Does that mean my upload speed 'may' return to normal levels when the work is finished on the cab?

At a guess, and it is just a guess, yes. Given some good lengthy of stability.

Have you just installed an ad-blocker or similar application that monitors network traffic? One that I used to use did exactly what you said.

No. The only program I have used is called DuMeter - used it for years! However just uninstalled it & still only 7 Mbps upload - now installed it back smile
