Drop in upload speed


[link to this post]
 
Hi

Just noticed since a couple of days that my upload speed with Sky Fibre Unlimited has dropped from a typical 6 Mbps to now an average of 2 Mbps. I have to say that while noticing this I have also observed the following changes:

1. Improvement of DL Speed from 25 to 27 Mbps
2.Improved ping response from a typical 25ms to 15ms
3. Variation in Output Power (dBm) from a tipical 3.6 in Upload to now 1.9

Point number 3 seem to me the one who looks it could be the culprit although I am not sure

With degraded upload speed I have the following stats:

Max: Upstream rate = 7357 Kbps, Downstream rate = 44545 Kbps
Bearer: 0, Upstream rate = 7373 Kbps, Downstream rate = 27398 Kbps

Link Power State: L0
Mode: VDSL2 Annex B
VDSL2 Profile: Profile 17a
TPS-TC: PTM Mode(0x0)
Trellis: U:ON /D:ON
Line Status: No Defect
Training Status: Showtime
Down Up
SNR (dB): 10.7 6.0
Attn(dB): 25.4 0.0
Pwr(dBm): 11.4 1.9

With a speedtest taken before having this issue the upload speed would always show at an average of 6 Mbps where now has dropped to 2Mbps although in the router stats the uplink shows at
7373 Kbps

So to resume, what I have seen in the last couple of days was that ping response improved by dropping from 24ms to 16 ms
Download speed increase of 2 Mbps
Upload speed dropped from 6 to 2 Mbps.

Is there anything from the router stats that indicates this issue being somewhere particular?
Thanks

Post a link to the speed test results from http://www.thinkbroadband.com/speedtest , there may just be a clue in the shape of the speed test graph

No sign of errors, looks capped by something and if the sync speed figures are correct them not that.

If you have not already when its daylight I'd switch off for five minutes and back on. Just to ensure the end to end path gets rebuilt

I am sorry,

I realized it was me forgetting I had a traffic limiting rule on the router which was meant to manage another internal IP but this has apparently affected the all outbound traffic.
All good,
Thanks for your responses.

We've all done that sort of thing many times, so don't worry smile.
