Engineer Still Unable To Fix Despite New Hardware..

If you joined CF in December then will be subject to IPv4 carrier grade NAT. Your WAN IP on ASUS router will be something like 100.x.x.x and different to what https://ipinfo.io says.
Hmm, my WAN IP on my router is the same as the one that thinkbroadband and that website suggested...can't see anything starting with 100....

I wonder if CF support switched you after all the issues you had, very bizarre. Did they mention anything on this topic?

Absolutely not, had one email response in the six weeks I've been trying to contact them and it was generic to ask me if I was still getting issues after I rebooted the router etc. Pathetic levels of service so far to be honest, highly disappointed. Fortunately you guys have been unbelievable help so far...I will try to suffer however long on hold tomorrow to see if I can actually speak to someone, I gather from here they are at least semi helpful when you do get though!
 
Sorry to hear your CF customer experience has been so poor. Armed with the stats from thinkbroadband and a 149.x.x.x IPv4 dynamic IP there does look like an underlying issue that needs further investigation.

Keep trying and complain when you do manage to reach them and get additional free months service.

Thank you. I will keep you all regaled! Again, really do appreciate the help!

Good luck and insist they check the OLT port for errors as packets are being lost somewhere between the remote equipment and your ASUS router.
 
So I got through...the guy said he did some initial tests and the speed was fine and the power looked fine...I asked him to do more tests and he noticed duplicate MAC Addresses...we did a disconnection while he cleared them his side and he asked to continue to do the ping test from think broadband over the next 24 hours and see how it looks...
 
Some progress but will take time to pass through 1st line support to an engineer visit. Hopefully armed with the thinkbroadband quality monitoring and video calls dropping it will get resolved soon. Since moving to CF my old FTTC disconnection woes are a thing of the past and it’s been solid. During the cold & wet winter months copper was too unreliable.

To be fair since he reset the MAC address issue I've anecdotally found it better, but my wife struggled with Zoom calls on Friday while we were both wfh. The thinkbroadband test was a bit better but still some issues over the last 24 hours as you can see...

May be a case of another call I think. Still, I do think it's slightly better at least...

I use MS Teams/Zoom every weekday over WiFi and don’t suffer any disconnects or call quality issues so definitely worth following up. You’ll need to confirm the issues occur over wired ethernet otherwise you’ll be dealing with 1LS trying to make you change to different WiFi channels.

My wife uses Zoom, Google, Blue daily. I use Teams two times a week and never see any disconnects. We are both over wired ethernet. As I use pfsense I setup a gateway group between my CF and VM connections. This means I have active monitoring setup based on packet loss and as soon as CF shows packet loss it will swich the default gateway to be VM. It also sends me an alert to my phone. Over the last 2 months I had only 1 alert on CF on 12 Jan 4:09am and it only last 1 minute so it's likely that it was a network update on CF's side. The VM connection is a lot more unreliable.

Even a small spike like the ones on my image would cause an alert?
 
That's indeed better but a couple of problems. If you are in London 8ms is way too high as a ping time, see below for mine tends to be 0-2ms. And your upload should be around the same as upload, ~940mb which is the max possible once you consider the ethernet and TCP/IP overhead.

600down/700up over wifi is extremely good, assuming it's wifi 6. You are unlikely to be able to improve much on that unless you get a wifi 7 setup. And in any case most of your wifi devices won't be able to use that much speed so it's best to focus on stability and latency after achieving few hundred megabits in speed.

Yes the key for stable and rock solid wifi mesh is to move to wired backhaul. You will reduce in half the amount of traffic that will go via wireless making what's left using wifi much more reliable.
I see you are posting results from your computer rather than the router speed tests.
Is there a reason for that?

My router can report >900Mb upload speeds and <1ms pings, but my computer cannot. It also gets >920Mb d/l, but u/l and ping are higher.
Could that be computer performance, as it is 10yr old workstation. (all be it with SSD and plenty of RAM)

Indeed you need decent hardware to max a 1Gb connection. SSD is irrelevant in a speed test. It's all about CPU, memory, your network card and it's drivers. Anything USB will struggle to max 1Gb unless it's a 2.5Gb/10Gb adapter connected to a type C port that can handle those speeds. But that didn't exist 10 years ago so USB for you means slow. Finally "10yr old workstation" doesn't really say much. A top of the line 10yr old workstation should be able to max 1Gb connection but I am guessing that's not what you bought 10 years ago. So age doesn't really give much in computer hardware. You really need to know the specs to understand what you have.
 
My machine can read/write on local HDDs at ~2Gb/s, including over USB3 (though my network is not USB, the Ethernet port is on the MoBo.

It is an overclocked 2500k (ok so more than 10 years old) on a P8P67pro MoBo with 16GB 1600MHz dual channel ram

This should be obvious but the fact that it can do HDDs at ~2Gb/s doesn't mean the embedded NIC chip can saturate a 1Gb. Data moves in different pathways. Likely is that the manufacturer of the embedded NIC chip of your motherboard aimed for close to 1Gb speeds and 900Mb was good enough for them. You never noticed before because you didn't bother to check but it was never able to saturate a 1Gb link. You also need to consider that to saturate a 1Gb both sides (sender and receiver) need to be capable of doing so, otherwise you will be limited on one side and not saturate the other. Buy a PCIe network card with an Intel chipset and it will saturate your 1Gb no problem and should get 940Mb. Also always use the desktop speed test apps as they will perform better than the ones in the browser.
 
Yeah very true, the eSata (remember those) controller struggled with high throughput in port-multiplier mode (another one of those potentially useful but lost to history capabilities)
 
Engineer came who to be frank didn't impress me, spent most of the time talking about how good he was at his job, said the power on the optical line was 24.7 and so within the range of being fine, finally noticed the uneven up/down speeds after trying to tell me in the first 5 minutes it was the issue of my Asus router and not their equipment, and decided to replace the modem and the router apparently. Got parallel speeds and so he left. Sadly the rest of the afternoon while using their Linksys was worse and worse - websites just not loading. Speedtests showing 4Mbps then 0.5Mbps. Tried rebooting modem and router, which took a few minutes to reconnect, still negligible difference.

Spent another frustrating 30 minutes on the phone having to convince them that getting 0.5Mbps upload speed while 1 foot from the router was not to do with the Wifi connection...and someone else is coming on Tuesday to potentially see if there's anything wrong with the connections outside. Just the same crap from the customer support who are just going through scripts and not actually listening to me.

Does anyone have any suggestions...please...I'm at my wits end. At this rate I'm tempted to just cancel them and see if Hyperoptic at £77 a month instead of £25 a month will make me less frustrated (provided they can use the same hole in my front wall!).
