DV Adapter died.

flyhighest — Fri, 19 Jun 2026 13:48:38 GMT

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.😶🤞👍

@bobpullen Both adapters, and the Fault is reported as a Solid Red connection light i think.... Was not able to find the OLD BT version document anymore, have a copy so will take the quick look at it....

Ah ah! The fog is slowly clearing. I'm new to the Community so still feeling my way around. Thanks for the links. My working assumption can now be that it's the Hub's firmware that's at fault - and that it will upgraded in due-course (viz. soon-ish).

Re Ethernet, I did notice the little connecting-symbol before the monitor symbol turned up. Was always only an inconsequential few seconds but I see that was another firmware bug.

Funnily enough, the phonecall that got interrupted was from my son who was testing his landline from his brand new router (from Virgin) because the previous one had gone duff. Oh what fun we had working out what had just happened. I phoned him on the mobile at the same time he phoned my landline on his mobile - I couldn't reach the phone ringing upstairs in time and he couldn't answer his mobile because, like me, he doesn't have it tethered to his ear all the time. I wish we could revert to string-and-tin .... or smoke signals.

@flyhighest It may come down to the old way off working, moving from sky to vodafone they dropped the pooch with the Landline operation, i just gave up on it all, patience just wore it all down..... Toy's out the pram and stuck the VF hub back in its box, that is the best place for it as not very good at all for MANY many reason's.....

Just no point in you faffing about currently, wait until you get the stable FW update then go on attack mode for more fun!

How hot? A deadly amber warning is in force, but it's just rained and it ain't hot. Not an electrical fault - the sockets upstairs and downstais are on different circuits. Both DVAs failed in both places. I'll grant that there could have been a transient power supply failure which we do get - but there wasn't. We have a nice traditional clock radio that signals the slightest interruption by reverting to midnight - as do our oven clocks. So, no, not electrical supply. Also, I would expect DVAs and the router to cope with transient outages - if my PC can manage to survive a quick blip, then so should DVAs and Hubs either survive or quickly recover from a quick blip.

But then, big organisations never fail to fall below one's most basic expectations. (Although, fair do's, I've got through to EE on the phone a couple of times now with relative ease and speed, and, glory be, they spoke English, even though one was Irish English and the other Welsh English, I'll take that as a win because I speak Scots English!)

Latest (and last) update:

After a transient power outage (unrelated to Broadband) the Hub powered back up, but both DVAs went blank (neither was on the circuit that flipped) and wouldn't come back. After a while of deadness, I moved them to next the Hub, and eventually (multiple unplug replugs) their lights came on and they reconnected. Moving them back to their proper positions, both went back to being dead. Hours later, they re-established contact. Meantime, phoned EE yesterday and they detected the Hub didn't reach minimum speed as contracted, thought that was the cause of the DVA issue, and ordered an engineer to come out and test both problems: blank DVA and slow speed.

He arrived this morning. Re slow speed, he simply didn't accept that we had only a Junction Box and no Master Socket. I well remember three Extension Sockets being installed about 40 years ago so we could move the phone (hard-wired into the Junction Box) away from beside the Junction Box in the hall by the front door (these were the days before cordless phones - even the ones with the big long aerials). I well remember asking BT to provide a Master Socket in place of the Junction Box and they flatly declined (even at a price) because it wasn't broken. So don't tell me I have a Master Socket.

The upshot is that the engineer installed an Openreach Master Socket in place on the Extension Socket that feeds the Hub. It's ten or twenty feet away from the Junction Box and I have no idea of the wire's route which has to involve going under the bathroom and the airing cupbaord. The engineer explicitly ('cos I asked him) accepted that Openreach/BT was now responsible for everything up to and including the Master Socket. The Hub speed was improved somewhat but still not up to standard, but I don't mind because I'm not a heavy user.

Re DVAs. The one downstairs failed in front of his very eyes. Blank. The mains socket is faulty - let's use the next one - it worked. I insisted he unplug and replug the DVA: it failed. So, two sockets duff? He came upstairs with a new DVA and plugged it in near the router - it failed. So, three sockets duff? So, he plugged it into the extension lead nearby - still duff. So, four sockets duff? No, he had forgotten to switch it on at the wall. And then it worked - and continued working in both of the so-called duff sockets downstairs.

Apart from "I've never seen these things just go blank before" - well, he has now - he had two messages for me: these DVAs are rubbish and you'll be going FTTP "by the end of the year" so all this will be obsoleted. No - the DVA problem will remain if it's them wot's duff. "by end of the year" - also no, Openreach says "it's 2027". I don't want it and I don't need it and I can't see anyone with any nous thinking carefully and sensitively about where and even how to plunk boxes on my walls/cladding inside and out.

So, the duff DVA issue remains. The engineer's analysis of what issues there were was poor and his fix more suck-it-and-see, especially having sucked it he saw the DVA blank. But I've got a Master Socket for free. I have a DVA-avoidance workaround in mind - but I will in practice lose the answerphone function. Once upon a time, phones were simple and reliable, now modern technology has crushed the life out of them.

@flyhighest Hair pulling out, surprised you did not have an old master socket somewhere in all of those but never mind, the latest OR 5C Master Socket is good to have, regarding the DVA light, @JordanTA the product specialist all things DV and DVA, copied now so may be able to throw some light on it, no pun intended....

FTTC copper connected, just try to keep the hub on powered up if possible and let the system steady itself and work it's way up, sometimes the OR Engineers will go reset the Dslam to get you up quicker to full speed, just all depends on what was getting done and how the Engineer felt at the time, Does require a OR Engineer, contractors may not be allowed to do so.... 10 Days training period begins now!
