BT Business Smart Hub 6: "a device reset was performed. Reason SAAF(5)"

praful — Thu, 03 Jun 2021 08:55:38 GMT

I've been using a BT Business Smart Hub 6. The WiFi signal is much improved over the PlusNet One Hub router. I'm also getting slightly faster WiFi and wired speeds (71 vs 74) but the speeds with the One Hub were fine.

I've seen reports of the router restarting or or losing connection without warning. I've had two issues.

The first occurred five days after installing the router:

dsl:VDSL Link Down: duration was 38957 seconds

I did a line test (17070, option 2) but all was quiet.

Early this morning (three days after the above event), I had a soft reset. Here's an extract of the event log (most recent events first, so start from bottom for chronological order):

If this sort of thing happens outside of normal hours, I can live with it but it seems unpredictable.

Can someone please shed some light on this? What is the solution?

Thanks

@praful

I suspect that these are two unrelated issues.

The first I imagine is a line drop, which occured nearly 11 days after the last drop. This sort of thing happens from time to time, 10 days without a drop on broadband is pretty good, several times a day is bad.

The second as shown in your event log looks like the warm reset all Smarthub 6s go through every two weeks. This is normal.

I strongly suspect that they occured three days apart is pure coincidence.

My apologies, I have got hours and days mixed up.

This first drop is the one that you should keep an eye on, I assume that you had two drops about 11 hours apart (or is it just one drop 10 hours after you installed it? If so it could have been a firmware update.. As I suggested before I doubt this is anything to do with the warm reset or indeed the hub.
If you start getting regular disconnects I suggest that you raise a new topic on the fibre/ADSL board as appropriate, asking for a Plusnet staffer to generate a radius chart. This will show us the number of line drops that you are getting.

@Baldrick1 thank you for replying. I had read about the fortnightly BTBHub6 reset and thought nine days was too soon after installation. But maybe it's on a different schedule.

My apologies, I have got hours and days mixed up.

I was just replying to your previous message, asking how you deduced the "nearly 11 days"

The most recent VDSL drop, which is not in the above log extract, occurred at reset:

05:32:42 03 Jun. dsl:VDSL Link Down: duration was 376555 seconds

So that's a reasonably healthy 4 days.

If you start getting regular disconnects I suggest that you raise a new topic on the fibre/ADSL board as appropriate, asking for a Plusnet staffer to generate a radius chart. This will show us the number of line drops that you are getting.

Thanks - will do.
