Low SNR, patchy network

[ImTheReal]

Hi,

I just had an unsuccessful session with support chat. Testing my luck here.

I'm seeing the following on my modem (Draytek Vigor 167) DSL Status page

I'm experiencing quite patchy broadband in the recent days, especially today. I've been dropped out from calls and meetings. ping constant shows network is unreachable packets in dozens or more at a time.

I did see DSL led blinking (searching) on the modem at the same time when packet loss happen.

An engineer visited me recently as a pair of cables got worn out after a renovation in communal places in the building. Engineer told me that we might see each other again.

Can someone see similar signal quality issues from talktalk side on my installation? Would appreciate some real help as I work from home and fast & reliable network is crucial to me.

~43Mbps with microfilter + router direct to the wall socket

Hi,

Great thank you. If you could post back here once the router is connected at the test socket then we'll re-run the tests again.

Thanks

I have no landline phone device. I can do that direct connect with microfilter in the morning. let me do that right now

[Michelle-TalkTalk]

Morning,

I'm sorry to hear this. I've run a line test now which is detecting a potential fault. Is your voice service ok? Would it be possible to connect the microfilter and router directly at the test socket please so we can re-run the line test again in this set up?

Thanks

Michelle

Looks like same pattern is back. 😕 speed test also maxed out at 50. no lost packets yet, but latency is going up and down.

Do you see any reason for this?

I've seen ppl from telecom company working on the streets around.

update: didn't improve overnight 😄

Hi ImTheReal

Thanks for your reply.

If the connection remains stable and errors on the line are low then DLM may continue to make changes to the line profile.

If you do experience any further issues then please let us know.

Thanks

That clip you posted is a wee bit misleading. The target SNR for any ADSL/VDSL connection is 6dB and can go as low as 3dB if conditions are good. Yours is higher with plenty of leeway because you are on the fastest sync speed available.  So things certainly look OK and stable.  🙂

[ImTheReal]

Things look promising. My guess some work happened in my area that caused the temporary issue last week.

I meant the talktalk router you sent me. That's what I use as secondary device because I need the modem in bridge mode to be able to use my own router (Mikrotik)

---

Sidenote:

I did go through the pics I uploaded and monitored line quality in the recent days.

I found a useful guide on SNR and what's considered good/bad value:

This pretty much overlaps with my experience.

Whenever SNR went down near 7, line has became flaky and has been disconnected frequently.

As is now, I have reading 9.6 on downstream and 13.1 on upstream:

I hope these values stay if not improve over time :]

Not sure anything can be done here right now. Things look ok and stable.

Thanks for the help

Morning,

No problem, please let us know how you get on. Do you mean the original router? Did you receive a router returns bag?

Thanks

Michelle

[ImTheReal]

I'll run my own tests for a while as I have a proven working second device now.

Thanks for the help.

Let me know if you want back the potentially dead talktalk device as the one you just sent works fine.

I might reopen this thread when I see issue coming back and persistent on the talktalk device too.

Have a great weekend all.

Hi ImTheReal,

Line test is passing and router is in sync at 76.6Mbps, connection also appears to be stable at the moment. We can't actually see the SNR. 

Could you just leave the TalkTalk router connected for  the time being and monitor to see if you experience the same problems that you experienced with the DrayTek

Thanks

Chris

Got the package. Driver didn't take old device. They said they only deliver.

Just wired things up. Can you take a look and check if you can get more info out from this official talktalk device please?

Wondering if you can see details like SNR and other stuff about the line. Its UI not as advanced as my DrayTek, I can't see much comparison to the screen-crops I shared below.

Hope this thing expose bit more to you to have some extra metrics available at your end.

[Chris-TalkTalk]

I've just run a line test, it passed and sync speed is 76.5Mbps, so looks OK at the moment 🙂

Chris

[ImTheReal]

Awesome!

I've setup my own device with router mode. If you could just take a look to check if anything odd pops up right now.

If not then let's see how things will look like with the new device.

edit: I'll leave this as is and use my mobile hotspot for work today. I wired up with the test socket as you suggested before.

[Chris-TalkTalk]

I've ordered the router, it should be with you within a couple of days (probably tomorrow) - can you please use all the new kit when you test. I've also ordered a returns bag to send the old router back in

Yes you can try the BT hub if you like, it won't do any harm

Chris

[ImTheReal]

If it's free of charges then sure. Also any idea what to do with this one?

I have a spare bt business hub 5 if that could help in this situation while investing. Want me to set up?

I used this bt business hub before i bought the vigor167. 

[Chris-TalkTalk]

OK thanks. I can't see anything other than the router isn't in sync. I think we should try another router, would you like me to send one?

Chris

[ImTheReal]

I made it to give some lights again for a bit. Started with orange flashing quickly, then slow flashing, then solid orange. It's no lights again. Can you see anything?

[Chris-TalkTalk]

Could you just make sure that the power cord is pushed fully into the port in the back of the router, perhaps remove it and reseat it

Thanks

Chris

[ImTheReal]

Done.

I think this router (talktalk) is dead. No lights and no activity. Tried different wall socket for powering up. No lights, nothing.
