Full Fibre - From no issues to regularly slowness

[#1]

Had the service now for approx. 18 months, no issues at all until the last say 3 or 4 months.

The download speeds have dropped dramatically on a daily basis, peaking between 90 and 100, averaging between 60 and 70. This is on both ethernet and WiFi. I have screenshots of 40mb at 2:30pm, 50mb at 18:45pm, 80mb at 3am, there doesn't seem to be much change to warrant peak or off peak.

Few details about my current service;

Full Fibre 500
Hub 2

Email received on activation confirming speeds;

Estimated peak time speeds:
Download: 500 - 550Mb
Upload: 68 - 75Mb
Current line speed: 550Mb
Minimum Guaranteed Speed: 275Mb

I would suggest you contact PN. FF should not, AFAIK, do this unless there is a circuit problem.

[#3]

I'll have to do that then, it wasn't so much of an issue but now it's affecting day to day.

Hey @Harvey88 
 

I’ve run some tests on the line and haven’t found any faults affecting your service. However, those speeds do seem quite sporadic. Could you let me know what tests you’ve done with the router? I can also make some adjustments from my end on your router to see if we can improve the broadband speed.

Evening, thanks for looking at this! The results were from the BT Wholesale connection test when accessing the router, my wired PC were providing similar results from speedtest too.

I can typically recieve 450+ on speed test from my phone too on WiFi , during the day between around 1pm to 4pm however it struggles to reach much above 80.

One needs to be mindful of the possibility that a mobile device might have flipped from 5GHz to 2.4GHz WiFi connections if it found the 5GHz band to be less favourable.  That alone could be responsible for the variability of measured speed ... along with a host of other things, including but not limited to, local congestion of the WiFi spectrum and remote congestion over the exchange back-haul.

@Townman  If the OP can get 450Mbps on Wi-Fi at some times it would suggest that there is noting wrong with the actual FTTP connection as a help team member has said there are no issues with service, as to what adjustments can be made to the router to improve the speeds is questionable. I think more investigation of the local equipment and network is required.

@Harvey88  Are you using any power over ethernet devices as they can result in poor speeds. What speed are you seeing with a direct ethernet connection to a PC. Speeds on a full fibre connection should not exhibit the slowdowns that you are reporting.

I've added some screenshots to my public album, couldn't see an obvious upload image on the mobile site, I've had pretty solid speeds from both 2.4 and 5 channels on a regular basis, the 400mbs and 499 screenshots were taken from my phone on the 2.4 channel and that was very common.

There's also 3 images from the BT Wholesale test with all connected devices forcibly disconnected prior so no risk of any equipment tampering eith the results, it differed between 60mbs to 90mbs within a 20 minute window.

I run a PC now on a TP-Link powerline adaptor as it has been moved to an outside office, though I don't consider that much as I expect deterioration, when it was inside exclusively it would achieve 500 almost religiously, though that dropped to around 100mb for around a month before relocating it. My partner now works from home and connects directly to the router via ethernet for teams meetings, we often see stuttering and find the speeds during the day to be much lower (60-90), and this fluctuates quite rapidly.

@RealAleMadrid

I would expect that the support staff will be investigating the WiFi spectrum.

@Harvey88 

TP-Link powerline adaptor

You might not be able to achieve full speed using those, which model are you using?

For example if they are TP-Link TL-PA4010 then the connection will be limited to a maximum speed of 100Mpbs

Heya @Harvey88,

Thanks for getting back in touch. I’ve made some changes to your router. If possible, please disconnect your devices, reconnect them, and test the speed again.

[#12]

@Marsh

Out of interest, what changes have (can) you make to the router?

We are aware that you can inspect the wifi spectrum and change the preferred channel … which would not require a reboot … so what other tweaks are available please?

Are they available to EUs via the UI?

[#13]

The TP-Link I have is mega old, years old now, so I knew not to expect much from that, I'll be getting a new model for Christmas though, I actually get higher speeds on the PCs WiFi than the TP!

[#14]

Marsh, while not yet able to check a wired connection until perhaps Monday afternoon, on WiFi I'm achieving 509mbs, BT Wholesale test is showing 320 down and 70 up, oddly the upload never dipped below 70, it was only ever the download that was affected whether directly wired or or WiFi.

[#15]

Good question, IMO.

It'd be rather transparent if such changes were reported on the router logs.
