Reduction in sync speeds

philipm — Mon, 17 Jun 2024 15:42:13 GMT

On returning from a week away I notice that my sync speeds had dropped, along with a commensurate fall in download speed. Normally I would be syncing around 47 or 48 down and getting a download speed of around 43 or even 44 mbps. This has now fallen to syncing at 40mbps, resulting in a download speed of 37mbps. Router has been powered off for 40 minutes then restated and that was 24 hours ago. No change. Might not sound a lot but a 10-15% reduction in speed when I have people working from home and I cant get full fibre is, actually, a lot so I'd like to know what the cause is and for it to be rectified.

Hi @philipm

I'm sorry to hear this.

The line test is clear - No faults detected. It has picked up - Regular Interference Observed Daily.

Where is the router located? Is it near to any other electrical devices?

Thanks for replying. Router is where it has been for the last few years. High up on a shelf in a utility room, in the centre of the house. Nearest electrical thing is a washing machine. Not sure how any possible local interference would affect the sync speed, though. Surely, that would be external.

Regards

Hi philipm

Is your master socket in the utility room?

Internal interference can affect the connection.

Yes, it is. It was moved there, years ago.

Nothing has changed for years so I cant see how I would suddenly be getting interference when I didn't have that problem a fortnight ago.

Hi @philipm

Ok, would you like me to send a replacement router for testing first so we can rule this out?

Re: Reduction in sync speeds

philipm — Tue, 18 Jun 2024 09:32:43 GMT

Sure. Let's give it a punt, unless there's a beta firmware that we could try.

I've got the Talktalk WiFi Hub

Hi philipm

We don't have a beta firmware sorry.

The router is on its way, please allow 48hrs for this to arrive.

Let us know how the speed compares with this router connected.

Thanks

Debbie

Thanks. I'll come back on this thread after I've set it all up.

All the best.

Ok thanks 🙂

Hi.

I've received the new router but checked all the stats on the old one before switching. Seems I am now back to syncing at 47.6 mbps which has given me a download speed on speedtest.net of 44.4 mbps. Exactly as it always has been. Not sure that the new router would improve on that. What do you think? Does what you see at your end suggest that I might be able to sync at any greater speeds? I am 0.4 miles from the green street cabinet by road so that has to be the maximum copper run. No doubt it's a lot less because I think the copper runs under the pavements.

Hi @philipm

I'm glad to hear that the router has arrived 🙂

It would be worth checking the speed again in 48hrs to allow DLM time to monitor the connection with the new router connected.

Thanks

Hi. Just to be clear, Debbie. I haven't actually connected the new router up yet. The stats I gave you were all for my original router. Would you still prefer that I set the new one up?

Regards

Re: Reduction in sync speeds

Debbie-TalkTalk — Wed, 19 Jun 2024 13:21:11 GMT

@philipm Apologies, I thought the new one was already connected.

Yes please can you connect the new router for at least 48hrs to allow DLM time to monitor the connection and adjust the profile/speed.

philipm — Wed, 19 Jun 2024 15:17:39 GMT

OK. Will do but that will have to wait until tomorrow morning now so it will probably be the weekend until I can update this post again.

Hi philipm

Ok, I will check the connection stats/speed again on Monday.

Thanks

Debbie

Debbie-TalkTalk — Mon, 24 Jun 2024 06:20:24 GMT

Morning @philipm

I can see that the sync speed has started to increase from 40mb to just under 44mb.

How's the connection/speed been for you since the new router was connected?

Re: Reduction in sync speeds

philipm — Mon, 24 Jun 2024 08:57:17 GMT

Hi.

Yes. 43.6 is the current sync speed. It's stayed at that all weekend. Ironically, if you recall, the old one was syncing at 47 before I swapped it out so I haven't achieved any improvement over that. Quite the opposite, in fact.

Re: Reduction in sync speeds

Debbie-TalkTalk — Mon, 24 Jun 2024 09:00:10 GMT

HI @philipm

The last test I completed showed that the line was in sync at 40mb.

Would you like to leave this router connected for a further 48hrs to see if the speed increases again or swap back to your old router?

Re: Reduction in sync speeds

philipm — Mon, 24 Jun 2024 09:11:58 GMT

I posted the old router back to you in the prepaid envelope so I can't go back to it. Looks like I'll just have to accept that there has been some degradation on the line. If it goes any more I'll have to get in touch again. Bit of a PITA really. We're totally surrounded by fiber but our single street has underground cables rather than telegraph posts so we cant get FTTP. I now have two people WFH so just try to eek out as much bandwidth as I can.
