Re: Sudden download speed drop

@vaper,

Yup that looks like a 'full' counter.  That's quite an old router - would you know what version of firmware it has?

PPP - that's the logical connection between your router and Plusnet.

I think you need to power cycle this router.  If there is an option to manually drop the PPP session (internet connection) in the router, please use that before powering the router off.  Leave it off for 15 minutes, then restart it and immediately grab the stats and post here.  That will do two things (a) clear all of the counters and (b) post a point of reference (time and stats) here for future comparison.

Re: Sudden download speed drop

Thanks townman, I'm wading through the user manual to see whether I can "drop the PPP session" on the router itself.

I came across a "disconnect" button on the Gateway site - would that do the same thing?

If I hit that button, will I still be able to easily get back on the internet again afterwards? I'd hate to be completely off air.

While I'm powered off, I'll also go over all the physical cable interconnections again to ensure good contacts from the router to the BT socket. Just in case I missed something.

Yes, that's the right option.  Note with some TG routers, if you manually drop PPP, after you have power-cycled the router, you sometimes need to manually RECONENCT the PPP session in the same way you dropped it.

Re: Sudden download speed drop

OK. Thanks townman - YOU'VE FIXED IT !

Carried out the power reset as you suggested. Re-checked all connections during power-off et voila!

Ookla speed test now measures 4.97/0.77 Mbps and data throughput back to ca. 600kB/s (using Networx graph)

In case they may be of some use, for future reference my DSL stata after the reset are as follows

Much appreciated townman.

How do you register a "Tank you" on this site?

 

EDIT

OK. Got the thanks thingy now.

Re: Sudden download speed drop

Keep an eye on the DS SNRM and the FEC count.  There's a fair few there for 2 minutes.

Re: Sudden download speed drop

OK I'll watch the numbers for a while but not sure what, if anything I can do about them.

I don't understand why there is such a large difference in the line attenuation in the different directions. Is this sort of difference normal?

Thanks again for all your help.

Re: Sudden download speed drop

The figures: what you can (or cannot do) will depend on what they show.  They will point towards what more needs to be done to deliver the optimal experience.

US & DS attenuation figures: well that's in the realm of complex technicality.  I will try to put it in simple terms; attenuation is measured across the transmission frequencies in use.  The DS uses lower frequencies and less of them.  The US uses higher frequencies and more of them.  ADSL2/2+ uses more frequencies than ADSL which is why it can be faster.

Higher frequency signals attenuate more than lower frequency signals.  Consequently US has a higher attenuation than DS.  ADSL2/2+ on a given line has a higher attenuation than ADSL.

HTH?
