BT Infinity & FTTx Discussion

Well, I'm pretty sure my line is fine at pinging, haven't seen much (if any) packet loss there.

It's during actual usage (as I've mentioned), in video conferencing and game streaming services like Google stadia, where I tend to get packet loss that has caused glitches in the video/audio stream.

Is this something a BT engineer can fix, or is some packet loss inevitable on many FTTC lines?

You want reliable data to go off before changing anything. Install SmokePing on a docker container or use TBB monitor as mentioned already.

Why do you refuse to listen to the advise you are given?

Set up TBB against your IP, enable WAN ping response on your router, post the graph in 24h.
 
My line is generally under considerable use for much of the day, which I'm sure would impact the results.

Saying that I did do this and maybe used QOS to limit the download/upload rate, what would be the next step after this?

Trying to convince your provider to send an engineer if the only issue is dropped packets. And trying to get the advisor to understand what dropped packets mean.
 
My provider (Cuckoo) sent an Openreach engineer last week randomly after I mentioned it in an email (just to query packet loss). Apparently, they had some down time, so decided to come and investigate.

I'm still trying to find out what (if anything) was done to the line. His tester device said 'line fault' a couple of times and he did some fiddling with the master socket.

There was a 2nd engineer who did some non specified work on the cabinet outside.

It won't, I use mine all day every day:

Why don't you just do it, instead of asking other questions and coming up with excuses?

You have come to ask for help, you have repeatedly been given advice by members on here, TBB and/or SmokePing have been mentioned pretty much every time yet you ignore it.

I'm done offering help unless you start paying attention to what is being said.

I, and others in here, generally know what we are talking about and the vast majority do networking or some iteration thereof for a living.
 
Are people referring to packet loss from the little red dots at the very top or other packet loss issues? I've never had a graphic with perfect no red dots unless the connection isn't being used. Others have mentioned on other forums to limit your upload/download to get rid of the little red dots that shows on the thinkbroadband meter.
 
There's no point, you buy an internet connection to make use of it, not to get perfect TBB scores. The TBB monitor is great at detecting peak time issues with your ISP but there's no reason to get obsessed with ensuring every ping gets a response.

That's the problem with these things. Too much information can be bad. Ending up pedantic. :cry:

Exactly this, @g67575 is claiming packet loss and issues with gaming. TBB would show this pretty clearly (I mean, we're all familiar with VM graphs). If it doesn't show obvious issues, the problem is unlikely to be their ISP and more likely to be the internal LAN.
 
Maybe I'm just expecting too much from FTTC. What is a usual amount of packet loss on a FTTC line?

I'm connected to an ECI cabinet, so no G.INP (retransmits packets before they reach your router, as far as I know). Maybe this is something that might've helped with packet loss?

As far as I can tell, my line tends to have less than 1% loss (but only when the amount of traffic is low on other devices). I'm 100% sure that there is some packet loss, as I can see this in Google Stadia (can be measured with the 'Stadia enhanced' extension). The precise amount is hard to establish.

Stadia tends to work well as long as the packet loss is less than about 0.1%, so it's pretty sensitive.

I'm getting FTTP probably at some point in 2024, as where I live in Worcestershire is covered by a 'White Area' for project gigabit (effectively delayed to phase 2).

It's possible to offer advice (or even just your opinion) without becoming irritated by what the other person is saying ;)

You're crapping up another thread though. You've asked a question, multiple people have asked you to set up a TBB monitoring graph and/or a smokeping instance and you just aren't interested.
 
I may try it at some point, but I'm having trouble even contacting my ISP at all at the moment.

What might help is if people with FTTC lines could tell me how much packet loss their line has, so I can know what to expect.
 
There's no number that anybody can give you for packet loss on an FTTC line as it depends on what service is being used. If you point me in the direction of a test you'd like running I will run it on my BT FTTC. If it's that Mlab test though I am going to stop replying.
 
So, here's the line stats on my router. Forgot to mentioned that the BT engineer must've reset my line last Friday.

So interleaving got enabled pretty quick on the downstream, downstream line rate increased from ~32,000 kbps to 50,000kbps.

Guess I'll see what the DLM decides to do next.

I'll try to get a BQM setup on my laptop, over ethernet.
 
Does the BQM test monitor my connection (via my router)?

Or, do I need to leave my laptop on? I can't see any kind of application running on the laptop.

I'm guessing it's designed to be left running all the time, and just pings the router in the background using only a tiny bit of data?
