SNR Reset

Arginine — Wed, 07 Sep 2022 19:48:48 GMT

I was wondering if someone from PlusNet could reset my SNR please? Previously ran fine at 6, has been increased to 9, and my speed has dropped from 10 to 7.

Many thanks.

Hi there, apologies for the delayed response to your post.

I've just done a DLM reset for you. Should hopefully notice a speed increase within 24 hours.

Let me know how it goes.

This solved my problem, but it has now happened again. Can I have another reset please? Is there any way to prevent this from continually happening?

I've done another DLM reset for you now. There'd be an underlying issue that'd be causing this. As line tests aren't showing the problem, it may be worth going through some troubleshooting steps Here in particular checking your router's plugged into the master telephone socket with no extension cabling between the socket and the router.

Additionally you could try plugging your router into the test socket explained Here to rule out any internal wiring.

Let us know how it goes.

Can I have yet another reset please?

I've been through all the steps you linked multiple times, and similar steps with previous providers. I've had a BT engineer over to check my internal set up and wiring on two previous occasions with another provider, with no issues found. The main problem is that I live so far from my cabinet and we experience a lot of poor weather and high winds. Whenever there is a particularly bad burst of weather, my speed is throttled significantly and then takes weeks or months to come back up, if at all.

Is there anything which can be done on your end to prevent this automatic reduction in speed and just fix it at a preset value?

I have done another reset now @Arginine the only way we can stop it is by turning the DLM off but it causes more problems if we do as we are unable to raise faults etc if it's not on.

@Arginine

There is zero point doing repeated DLM resets WITHOUT investigating the reason causing the DLM to shape line performance. There is every possibility that there is a fault. What has been done to investigate the cause of what is happening here?

Broadband is not going to work well if the "phone" line is not working properly.

Please perform a quiet line test - dial 17070 select option 2 using a corded phone plugged into the test socket behind the face plate of the master socket. It should be silent. A noisy phone line (or no dial tone) will have a marked adverse impact on the performance of broadband.

If the line is noisy or there is no dial tone, then a PHONE LINE fault needs to be raised with your phone provider. If this is PlusNet, you can report a fault on line using the button below. From the Q&A list, choose the one which matches the problem, 'open' the 'section' and click the trouble-shooter link. NB: If you receive a failure message (rather than a log-in prompt) then log-in to the user portal in a different browser tab and attempt to use the trouble-shooter again.

Phone Faults

How is your line performing?

Please post your router stats; for PN routers use the buttons below, for other routers look at the Kitz link.

Also run a BT Wholesale speed test (ideally using an Ethernet wired PC with the WiFi turned off) then run the further diagnostics, download the .PDF report and post the results here. DO NOT REBOOT the router!

Check the Plusnet user portal for the "Current Line Speed" which is relevant to users with static IP addresses.
