Re: ASDL very high ping.

The Plusnet Hub One is a BTHH5a for which there’s a customised version of RouterStats … which delivers good quality data.

That Rx margin plot is utter nonsense - SNRM is typically less than 21dB (ideally 6dB) - the scale of the graph is not appropriate. More over where a SNRM plot is concerned, where variable, a higher value indicates a better state of affairs than a lower one.

The very old link in my sig to configuring router stats referenced a thread which has been archived and referred to the excellent sagem router.

The BTHH5a version needs little configuration beyond setting the sample interval to 10 seconds and the graphs to 720 plots. That delivers 2 hour intervals per graph and provides clear visibility of short duration noise spikes.

ADSL can be adversely impacted by internal telephone wires. The fact that the router is not attached to an extension does not mean that they have no impact. They act like aerials picking up no end of RFI interference.

Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.

Re: ASDL very high ping.

Thank you for the instructions, sorry i did the totally wrong program initially. This is what I have now for the past few hours on router stats

this looks relatively stable, however i am having a lot of packet loss right now.. so i am quite confused

Re: ASDL very high ping.

Your Hub-One modem stats, and your noise margin plot, would suggest that there's not much wrong with the ADSL connection, and you probably don't have much (if any) noise related packet loss - just bursts of excessive latency where the ping replies take too long to return (showing as red stripes on PingPlotter).

 

So back to my original theory that something on your network is uploading at approximately 1Mbps and swamping your outgoing connection. You now need to isolate your internet so that ONLY your laptop is connected for monitoring purposes.

 

Can you power off every device in your house that might be connecting to your internet. including all mobile phones, TVs, games consoles, etc.  so that ONLY your laptop remains connected ? - then see if the latency disappears,

 

If the latency is still there (with only your laptop), can you open your operating system's 'system monitor' graphs, and see whether the laptop's network port is transmitting anything ?

Re: ASDL very high ping.

Yes I can try that, only my laptop is connected now to the hub and I am still getting the latency on pingplotter.

do you mean the resource monitor app?

I have that open and see the graphs but I do not know where to go from there to check if the network port is transmitting.

Re: ASDL very high ping.

@Albut17 

If you look at the last ping graph which is actually a trace route I see the average ping to the Hub is 10ms, that is not a good sign, mine is usually around 1ms even on a wireless connection.

For reliable connection testing pingplotter should be running on a wired device connected directly to the router or via switches to the router NOT via powerline adapters or wireless.

Do you have any device which streams data on your local network?

Re: ASDL very high ping.

What would the high initial ping to the hub indicate?
All I use on my network apart from the laptop is two iPhones and an iPad. I do not have any other smart devices nor gaming devices in the household. All I could think of was the iCloud backup on the phones that could be trying to upload so I turned that off yesterday.

Re: ASDL very high ping.

When you had your laptop using a wired connection to the Hub did you see have the same results as now with regards to packet loss.

A weak wireless signal reduces the speed of the connection between the wireless adapter and wireless access point in this case your Hub One. 

The problem with detecting packet loss is that some devices in the path to the target might not respond to all ping requests, a missed ping request would be detected as a dropped packet. End to End ping test is really what would be of concern.

The bottom line is are you suffering as a result of the perceived packed loss?

 

EDIT: have you checked to see if Full Fibre is coming to your area soon? Although you'll lose your landline phone slow speeds will be a thing of the past.

Re: ASDL very high ping.

Yes I was still getting the packet loss while connected via ethernet but I think I have got somewhere today. I have turned the wifi off on my phones/tablet and I am no longer seeing the issue on the pingplotter.

I suppose now I need to isolate which device is causing the problem and why. As I said I turned off all the icloud backups as I thought perhaps that was the issue but thats not solved it.

My connection is definitely suffering, The most obvious way is that I have been unable to sucessfully video call anyone for almost a month. The other person can see me but I either cannot see them at all or their video streams for a second and then stops or I get a frame every second or so. This issue never happened before a month ago and I am just baffled as to what has changed since then. Other than that I have had daily issues with buffering on Iplayer and other streaming platforms. When it is at its worst though I cannot even connect to run a speed test, whatsapp will get stuck on "connecting" etc.

Full fibre is available here but I am in contract on asdl until july.

Re: ASDL very high ping.

Having a slow broadband connection is not the best, have you checked for wireless congestion?

With regards to Full Fibre if it is supplied by Openreach you can upgrade with PlusNet or move to BT/EE to keep your landline phone with no contract exit fee . But if it's an Alternative network on City Fibre then there will be an exit fee.

Moving way from plusnet to BT/EE or an alternative network you will lose your plusnet email which might be important to you.

The clock is ticking for the end of PSTN service, plenty of posts here on VoIP options if you want to keep your landline number with plusnet Full Fibre or an alternative network.

Good spot Dan !

Here's mine -

I am hoping for a miracle to happen when I plug that in Smiley


 

As your ongoing tests are confirming my initial suggestion that it is your ADSL's UPLOAD path being overwhelmed by a mobile phone on your home network, the bad news is that for this specific problem, time and again in this forum it has been shown that the Plusnet Hub-One router works better than the Hub-Two at coping with upload path overload. So don't hold out much hope for a miracle when your Hub-Two arrives !. 

However if you can cure your rogue Apple device(s) from sending too much data, the good news is that the Hub-Two does have a pingable WAN port, therefore you could setup the ThinkBroadband BQM latency plotter to be able to keep an eye on how your connection is performing.

 

Apple products are notorious for the problem you are experiencing, described by posts like this - How do I limit the upload speed of iCloud 

Having said that, you might want to try this - Use Low Data Mode on your iPhone and iPad  on the off chance it makes your situation less bad.

@Albut17   That raises four questions -

 

1)   Is your available "Full Fibre" from BT Openreach, or is it a third party AltNet provider ?

 

2)   Do you currently use your landline telephone ?

 

3)   Are you aware of the Openreach conversion of analogue landlines to digital telephones, due to occur during 2025 ?.

 

4)   Do you intend to keep using your landline phone after the analogue PSTN switch-off ?

.

[edit] my post overlapped with some of the same points made by Dan, but would still be helpful if @Albut17  answered my questions

Re: ASDL very high ping.

I am not sure if what I did with the routerstats program yesterday was to do with wireless congestion i apologize I am not very technical with these things.

I did not realize I could change to fibre already while on contract the bt engineer last week didn’t seem to think that I could so that is interesting and something for me to think about. I will need to keep my landline though as my mother uses it quite a bit.

It certainly does look like it is one of my iphones that is causing the issue, after i turned off the wifi on all of them i slowly turned them back on one by one to see if I could identify which was causing the issue. Everything was fine for about an hour but now the packet losses have returned with a vengence. I will try the low data mode you suggested, thankyou.

Re: ASDL very high ping.

Just to confirm yes we have full fiber with bt openreach available here. I am interested in upgrading but I definitely need to keep my landline.

I wasn’t aware until just now that I could switch to bt/ee in the middle of my contract so that was the only reason that was stopping me from upgrading previously.

When the bt openreach engineer was here last week I told him I was still in contract and he didn’t say that I could still switch so that’s what confused me.

With respect, that isn't something an engineer would know.

Re: ASDL very high ping.

@Albut17  upgrading to Full Fibre, sooner rather than later, solves several problems -

  • You wouldn't need to 'cripple' your Apple devices performance just to work with your ADSL broadband
  • Your video calls would have more than enough bandwidth to eliminate all buffering problems
  • Your line latency would drop from your current best of around 30ms down to single digit milliseconds

 

Attempting to convert your landline phone to VoIP on your ADSL (as it is) would be nearly impossible, whereas using FTTP will be perfect.  Bear in mind that unless you act soon, Plusnet will be forced (by BT Openreach) to remove the telephone number from your account (before end of 2025), which would leave you with a problem as ADSL minus phone number becomes SOADSL - which Plusnet don't support,  so you would also lose your internet.

 

Don't waste any more time trying to get ADSL working, get upgrading ADSL to FTTP, then PSTN landline to VoIP.

 

My advice -

1)  Initially upgrade to one of Plusnet's slower FTTP speed options - you can easily upgrade speed tiers later, but downgrading is discouraged and expensive.

2)  Upgrading from ADSL to FTTP will put your landline phone number in to 30 day quarantine, during which you then migrate the number to a VoIP phone supplier (such as A&A)

3)  DO NOT attempt to migrate the phone number to VoIP before your FTTP is fully up and running, otherwise you risk Plusnet account closure !

 

GOOD LUCK !  👍
