TP-Link TP-W9970 router keeps disconnecting

Biz55 — Tue, 27 Sep 2022 18:58:31 GMT

My old Plusnet router broke down after years of service so I bought a Tp-Link W9970 about a month ago. I followed the Plusnet instructions for setup and it works well when it's connected.

However even from the outset it would lose connection at least once per day and needed to be rebooted. Recently it has begun to disconnect more than once per day. So I got BT to check my line and it was OK. Plusnet sent an engineer to my house and he confirmed that everything was working fine.

So I'm wondering if this router is the problem. I have just updated the firmware but it still disconnects. Perhaps one of the advanced settings needs to be tweaked?

Any suggestions would be greatly welcomed.

Some line stats please. Also is your connection ADSL or VDSL?

Whoa, 57 errors. Even on a noisy line I’ve never seen any errors reported there.
Which version is it as there are quite a few different ones out there now? (7 last time I looked)

Are we sure it's VDSL ? , those figures look suspiciously ADSL ish, either that or the distance to the cabinet is quite large

If it is VDSL then there is a problem, the Upstream looks to be capped

A screen dump ( redacting any phone number ) of the expected speeds from the BT wholesale checker https://www.broadbandchecker.btwholesale.com/#/ADSL would be useful

I just ran this again and have 15 errors after about 15 hours. Is that still unusual ? If so how can it be reduced?

The router is version 4. I updated the firmware yesterday. No disconnections yet today but we shall see.

Yes. It says DSL Modulation Type: VDSL2

I'm outside of a rural town so my speeds are never very high.

@Biz55 thanks for confirming that.

Yup, you are a long way from the cabinet!.

Your stats do tend to indicate a problem with the upstream though. Your upstream rate is below the estimates, whereas your downstream rate is above estimates.

Are you connected directly to the master socket ? and are there any other wired extensions ?

Re: TP-Link TP-W9970 router keeps disconnecting

Biz55 — Wed, 28 Sep 2022 16:07:57 GMT

Thanks MisterW

My router is connected to the master socket via about 7 metres of cable. Could that be an issue?

There are no other wired extensions in the house.

One other thing I have noticed.

Just now the router is reporting current download stream at 16213 kbps

On both ethernet and wifi fast.com is reporting just 5.6 mbps

Is that normal ?

Depending on the quality of the cable, very possibly.

Is it possible to connect with a shorter cable as supplied with the router ? then look to see if the synch rate(s) and disconnects have improved

Thanks I will experiment with that later.
