My BT FTTC has been dropping out this week, couple of times on Monday, again on Tuesday, and now twice so far today. Always between 5-7PM, rest of the time it seems fine.

Log I grabbed from the last dropout, anything obvious there? BT website test says they found no issues.

There's not really enough to go on if your router isn't even showing the number of errors.
-
That's all the info the stupid BT Hub 6A tells me when the event log is set to all, is there a way to gather more info?
-
are VPI / VCI used on FTTC lines? never seen it before when VDSL is the line modulation.
-

No, never.
. . . never seen it before when VDSL is the line modulation.
It is just the result of a decision by the writer of the system code (or firmware) to display that irrelevant information.

Anything else running at that time, boiler, microwave, etc?
-
Nothing new, or obvious
It did just drop out a few minutes ago, the kettle was on, but I don't think that lines up with the other dropouts
-
Things went back to normal for a month, then 6+ dropouts today
Is it normal for the BT Home Hub Event Log to display the wrong date every so often after dropouts?

Darn, that's unhelpful as we can see PPP drop but does it drop sync? (I'd assume so)

Your modem is rebooting - is not just a dropout.
Have you tried a hard reset?
-
Yep, left it unplugged for 15 minutes. It continued to drop. It's not the whole hub rebooting though, LAN continues to work (at least it seemed to while I was watching local media).
I ran another BT test thing and finally their automated system says they've detected an issue not at my property and they're going to fix it. Haven't spoken to a human so I don't really know anything else, I guess I just sit on it and hope for the best for now.
-
Is the modem itself ill? Need a replacement unit / or new PSU ?
-

Good point, I thought it was a user triggered reboot as I was looking at the time thinking "oh theres a gap", missing the obvious that the date was reset due to the reboot.
-
Yep, left it unplugged for 15 minutes. It continued to drop. It's not the whole hub rebooting though, LAN continues to work (at least it seemed to while I was watching local media).
Sometimes, especially after the HH upgrades it's firmware, it needs a hard reset to take.
This is not the same as switching it off/on but pressing the reset button at the back (or in the GUI) to reset it to it's default settings.
You can backup your config before doing this and reapply it once reset
-
Thanks for the responses. Seeing as BT are apparently working on fixing a fault their system identified outside of my home, I'm going to do nothing and see what they say. I haven't had any more dropouts since around 5am, so maybe they've already done something at the exchange or cabinet. Might be wishful thinking though! I'll make a note of any more dropouts and if need be I'll report back and try the factory reset/restore as suggested by gt94sss2.

OR engineer came out a little while ago, phoned me and came into my house after doing his external tests and then ran some internal checks. Said everything is fine with the line and he reckons it's either the home hub dying or my ethernet cable or switch making it drop and is going to recommend BT replace the hub and for me to call them tomorrow/monday.
-
Additional query;
I've found some posts online with similar issues to mine where it was only fixed with a 'lift and shift' and I'm wondering if moving from BT to say, Plusnet, would have the same effect. My BT contract ends next month.

Moving to any other ISP while remaining at the same address will change nothing on the distribution infrastructure, OR will have no reason to attend, all carried out remotely.
Your line however will get a DLM reset which after a few days with the new ISP will probably leave you back exactly where you started but with an alternative modem/router which may or may not be a better performer on your line.
Any VDSL service ISP you choose to use are subject to OR's infrastructure and service, with the obvious exception of cable services, some ISP's are better than others with respect to dealing with OR but that usually comes at a cost.
If OR are "happy" with the line and not willing to investigate further why not try a replacement modem/router preferably one which can produce worthwhile line stats, there are lots available S/H at very reasonable cost especially now with the ever increasing migration rate to FTTP and most migrants using their new ISP provided devices.
-
No. A change in ISP doesn’t change the physical arrangement of your line. It will cause a DLM reset however. I don’t see your problem could require a lift and shift.
-
I love you guys, very helpful.
BT are indeed sending out a new hub. I'll hope for the best and whine again if it doesn't help.
