DV Adapter died.

We've had EE Broadband & Landline for less than a month. Today we were cut off during a phonecall - dead silent. On checking the DV Adapter for the phone was off - no lights, no nothing. I tried the standard mains switch off -wait a minute - mains switch on. Still dead. Brought DV Adapter upstairs to beside router. Still dead. Tried re-linking as per instructions - router flashed blue but DV still dead and router went back to normal after a while. I think I did this twice before deciding the DV had terminally died..

After lunch, I thought I'd swap the second (working) DV we have (in our bedroom) with the dead'un. Took it downstairs - having been alive upstairs, it was dead on arrival! Brought it back upstairs next to router - tried again - dead - and tried again just for luck - and lo! flashing amber and quickly back on. Took it downstairs - it survived the journey and was still alive and working!

So, took the dead 'un and tried it upstairs - and the amber light flashed and it came on green. Tried phoning in - both DVs and router-connected phone all work. So, what didn't work (at all - parrot-like dead to the world) now does work. 

Is there any rational explanation for the dying and resurrection? Of not one but two DV Adapters. It happened once before and the helpful EE man at the other end provided the off-wait-on solution which worked first time.

Duff DV(s)? Duff Router? Not the right sort of ether? Haunted house with ghostly interference? Or perhaps the firmware issue that I've just noticed was posted here a few days ago? 

It's all a bit weird because I've lately had web sites on the mobile phone (which we've got set up for wi-fi calling because mobile reception if mediocre at best) cut-out and return, for no discernible reason. The mobile is giffgaff using O2's mast in our village. Giffgaff said the mast was faulty and engineers were working on it as we speak; O2 said oh no they not - all was 100% working.

Hi @flyhighest 

It sounds like some kind of glitch to me. It could be related to firmware too, though. Hopefully, the solution that my colleague suggested works again if it were to happen in future.

@flyhighest One off those chalk it up to not knowing and hope it keeps working most off the time! Link if you need it all about the Adapter EE based.

A glitch! That explains it all. It's good to know it's not a bug or even a gremlin - or maybe they are there in the jellyware?

Seriously, that's not a rational explanation, nor is it a solution to switch off and on - that's a workaround. And a substandard one at that, given that I switched off-and-on perhaps five times before something squashed the bug for a while.

Ah me! 

 

@flyhighest What actual EE Hub do you have, they are working on the FW that is having some adjustment's to the DV side on the EE Hubs currently?

Hope springs eternal. Your link is to the same little booklet that came with the DV Adapter. And nowhere does it say what it means when there is no light whatsoever ("On plug in, orange light will flash" - well it did not, no flashing, no light, just a blank black look of nothingness). That's why I myself and me have concluded (at first) that the DV Adapter was electronically faulty. But when the same thing happened to my second DV Adapter, something more fundamental is amiss - and it's not my house electrics.

"Smart Hub 6 Plus", order is dated 11th May, implementation was 21st May.

Am I right to I infer from what you say that there is firmware inside the DV Adapter that the firmware inside the Router can access and update? Hence, a firmware change to the Router can 'knock out' the associated DV Adapters, perhaps temporarily? But then, why did only one DV Adapter totally power-off (in the middle of a phonecall), whereas the other one remained linked (Green) until I unplugged it upstairs to move to our main phone downstairs, at which replugging it too went to permanent power-off?

The firmware version is r4.26.1-R-1860948-PROD-83002, apparently never updated (last update = "N/A").

The Technical Log shows no Warnings etc but doed show my main ethernet connection (to PC) going up and down like the proverbial you-know-whats upon power on, like it seems to do every power-on and sleep-arousal.

@flyhighest You have the Bad FW as mentioned on your post, the fault is found and the new is rolling out now to be completed by the end of June..... See also the linked from the pinned post at the first open page.... Don't worry to much about the fix as hopefully you get it soon, first reports are it's all back to normal whatever that is, EE just had an oops moment with it all!

The DVA as it is called operates down in the Dect Frequency range, between the DVA and the EE Hub, obvious they have to know about each other to work correctly, had you not been using a DVA then it may just not have flagged itself up in the way that it did.... And 100% correct not in the Manual, no light you have to suspect NO power, but then again as you found luckily it sparked itself back into life, so handy for anyone else who comes across your post!

The Ethernet is finally and alleged to be getting fixed, i used that EE Hub back in Mar 2024 and it had it all not operating correctly then one lives in hope! Also forget about the N/A there is never anything applied to that field you just have to watch the Forum for any potential that a user like yourself can spot!

@flyhighest - I can't see how the hub firmware would have any influence over the physical LED lights on the DV adapter. My view is that whatever happened, it was specific to the adapter/its environment and nothing to do with the hub firmware. Something in the hub could break pairing, but that wouldn't prevent the adapter LEDs from working.

How hot has it been where you are? I wonder if there's some sort of electrical fault that's susceptible to an increase in heat?

@flyhighest There is a section on the Forum that deals with it all the area is Home Services then drop down Digital Home Phone, better area for all that and what works/does not at times.😶🤞👍
