Had a power cut 2 days ago and i'm currently synced at 79999 / 20000 with a 2db SNR.

Wonder how long this will last for.

Well I do not know if I also suffered a minor power cut or what, but my router seemed to have reset itself just this past hour after 30 days of stable up time.

System Up Time 01h21m49s

Router speed has still re-synced at Actual Rate [Kbps] 80000 19999
Noise Margin [dB] 6.10 14.90

Normally system up time should not reset itself unless there is a power cut. But I was watching TV and there were no power cuts at all.

This same problem I had with Plusnet ADSL router where System Up Time would reset itself since around November. I believe it was a faulty Plusnet router.

But now I have experienced it again this time with the TalkTalk router. I only checked router stats out of curiosity and noticed the reset.

Before the cabinet upgrade my system up time in router would generally remain stable for months but would only drop out in connection. Maybe this is just a coincidence.

This time it appears that the connection was ok, but the router rebooted itself.

Maybe I need to use a Surge Protected Extension Lead for my router?

Why are you concerned about a router restarting every 30 days? When I had FTTC the Homehub 6 or whatever BT called rebooted every 14 days. Speed went up by maybe a megabyte or down by a megabyte depending on time of day or if the weather has changed significantly. Pointless fretting about it. A megabyte to me was 1/20th of my speed.

I don�t even look at my sync speed. If I noticed problems then I would.

I really don�t know why people worry about these things.

If I know for 100% certainty that this restart after 30 days was programmed by design then I won't be worried!
I was concerned whether this is related to a technical fault of the router such as overheating. Because under the old Plusnet ADSL router Sagemcom 2704n this reboot was happening randomly and it was a fault, sometimes 6 days, 13 days, 26 days, etc.

With Sky ADSL I had a connection up time of 56 days a couple of years ago despite having so many problems with ADSL reliability as noise margins back then had to be capped at 9dB. But the Sky ADSL system up time never ever restarted by itself, it would stay on for months at a time, only the connection up-time would reset!

Now I know at least in this particular case with TalkTalk it was not DLM or noise margin related as the speeds have re-synced at 80/20. It is not weather related as there were no winds, rain, etc.

You seem to be right that the BT Home Hub 6 reboots every 14 days by design. But I need to know that the TalkTalk Wifi Hub Fast 5364 is doing this every 30 days by design otherwise I won't know if I need a new router replacement. I probably need to consult on the official TalkTalk forums for clarification.

As far as the BT users are concerned some have said buying a new aftermarket router instead of using the ISP router solves this issue.

My extension leads are also over 10 years old which is something I am also concerned about and the router isn't plugged into a surge protection lead. I am looking to replace that and isolate the router from the other electronic devices, just for the benefit of the doubt.

Some routers reboot when the SNR Margin drops too low. Instead of just resync, they reboot the whole router at the same time. The only way to get around this is to have a separate modem and router. Unusual with ADSL, more common with VDSL (FTTC).

Would be interesting in you naming a modem that reboots when SNRM is low.

I don't even know of any modems that deliberately resync when SNRM is low, nevermind reboot themselves.
Modems resync when SNRM is too low because they can't hold on to the sync. It's not a deliberate act.

I last saw this on the BeBox, a Technicolor modem.

Well in the case of the Plusnet ADSL router Sagemcom 2704n I can confirm it was a defect with the router.

Because I had it with the first router and inquired on their forums and I then received a replacement in February 2019 and it lasted for several months until November 2019 when it finally started rebooting by itself.

When initially it was disconnecting only the connection up time was affected but the system up time was not. I think I accidentally damaged the Plusnet router when I first placed my new 1000W Inverter Microwave next to the router in my bedroom temporarily because in the kitchen I needed to sort out the brackets so it can fit there.

And after heating food in the microwave I noticed the router would disconnect and even after I had stopped using the microwave, I believe the damage had already been done. Because ever since from November until February the Plusnet ADSL router would randomly reboot itself every 6, 13, 20 days on average and it was progressively getting worse.

As for the TalkTalk FTTC router I have very closely kept an eye over the last 30 days and checked router stats every single day for a few times and I have not seen the noise margins drop to below 5.80dB and mostly hovers around 6.30dB.

I would find it coincidental that exactly when the 30th day mark occurred the router rebooted itself. You'd think if this was noise margin related then my router would lower the sync speed.

But anyway, I asked a reviewer on youtube who told me if this behaviour occurs again in the next 30 days that way I will find out and advised me to buy my own router instead as he uses his own so he couldn't give me his experience. I also asked on the TalkTalk forums and am awaiting a response.

If this is normal behaviour by programming at least I don't have anything to worry about. But if it is a router defect then I may have to request a replacement or look into replacing my extension lead to see if that has anything to do with it.

In the meantime the only way I can confirm if this is normal is if some other TalkTalk FTTC user can confirm if they've seen the System Uptime above 30 days. So far I already found out that certain BT Home Hub like Home Hub 6 reboots every 14 days and some after 30 days. But I'll need to confirm if this applies for the TalkTalk router as well.

Surely there�s more important things you could be doing than worrying about your router restarting every 6 days.

When I was in Openreach (I�m not now) the most recent training we had said that losing sync on xDSL once a day is nothing to be concerned about and quite normal. They didn�t even want us to waste our time on that!
