My V1 sure signal stopped working a couple of days ago. Most of the time only LED 1 is on, but ocassionally LEDs 2 comes on and LED 4 flashes a few times, then they all goe out again. I have been right through the troubleshooting guide, including resetting the Sure signal then leaving it for 12 hours, but it still doesn't work. I have provided below the information which seems to be commonly requested on this forum. Many thanks for your help.

PROBLEM SOLVED!!!
It turns out the black plug-top power supply unit was faulty, but this certainly wasn't immediately obvious. Anyway, I happened to have a spare PSU with exactly same specification (12V 1.5A), so I connected that to my Sure Signal and within 5 minutes it was working again. I wish I'd tried that sooner...
I hope that helps someone!
To all who have helped from Vodafone - Many thanks.
Technical details for anyone who's interested...
The plug-top power supply is rated 12V 1.5A. I tested it separately from the Sure Signal box and found that with no load, it produced the correct voltage (12V) and so I initially thought all was well. However, something made me suspicious so I tested it with a 12ohm resistive load as well, and it only produced about 7V (with significant AC noise) - Obviously faulty. My guess is that the Sure Signal draws relatively little current from the PSU during the setup phase and only gets greedy when it turns on its 3G transmitter. At that point, the supply voltage probably droops too far, causing the Sure Signal to reboot.

Hi IainGI,
Those details are all OK, and the lights show it's trying to start a connection.
I can see the Sure Signal connected yesterday morning. Have you seen any difference since then?
If not, reset and resync the box for me:

Dear Dave,
Many thanks for your reply. I did the re-syncing steps exactly as you described at 7am this morning. It is now 5.45pm and unfortunately the Sure Signal has not yet come back on line. The LEDs are doing the same as before, but it never gets to the stage where LEDs 1, 2 and 4 are all on and steady. Please let me know what I should do next. Thank you.

Hello, I have left it switched on for the last 24 hours, and unfortunately it hasn't made any difference. What should I try next? Many thanks.

I can confirm that this fix worked for me - thanks IainGI - my VSS version 1 hasn't worked for a couple of months and I'd put it down to issues with BT Infinity and my HomeHub 5.
Within two minutes of trying it with a power supply with the same specification the VSS was working perfectly.

Can't believe I just found this solution. My Sure Signal V1 has not worked for well over a year. Stuck in constant loop of green lights. Read this thread and went looking for a similar cable. Found one from an old external hard drive, 12V 2A. Plugged it in and hey presto, within two minutes box came back to life. So any of you with these symptoms, go get a new power supply.
I am amazed, just saved myself £100.
Thanks, thanks, thanks.
I posted this thanks elsewhere, but thought I should again to acknowledge you as the solution provider. Brilliant.

I was rather skeptical that a failing power adaptor was the cause of not connecting - but it was. Replaced power adaptor and it connected within a few minutes.
Tried again with original adaptor and no joy. Used new adaptor and connected again within minutes.
At the same time as these problems my broadband was playing up and I found that Vodafone had de-registered my box when my account was moved to a new platform. Vodafone said although de-registered it should still work. Seemed odd but I suspect the registration is on one platform where it was deregistered and operational on another platform where it still was known.
Of course I now have to add back all the numbers that were in my original registration - damn.

Strange one. I did the PSU change earlier this year and it solved my problem. However, over past few days my SS has been sapping all of my useable BB. Reset it, changed cables, fiddled about with router settings, all to no avail. Changed the PSU from a old BT router with only 1 amp, and it solved the problem. The PSU I changed to earlier must have a problem, manifesting itself by causing the SS to strangle my broadband.
