Sure Signal V3 suddenly stopped working

[jwinterton]

3 weeks ago my V3 SureSignal that had worked flawlessly for 9 months stopped. Power light flashing, Internet - Off, Service - Off, InUse - Solid Orange. I went through the usual rigmarole with Support but long story short they replaced it. Plug in the new one and it does exactly the same thing. After much fiddling with settings on my router I bought a new one for a few quid from ebay. Plugged that in and VSS immediately works. 

You would conclude that the problem must have been my old router but that doesn't make sense. Old router still works for everything else. The config and firmware are unchanged for months. I flushed the config back to defaults (even though it previously worked). All no joy. I am not specifically forwarding the required ports but nor am I blocking them. This has always worked fine (I have owned every model of SS).

My old router is an excellent Draytek 2830 with 3 WAN options - ADSL, Ethernet, USB. 

So in a bizarre test I plugged my old router into the new router via it's Ethernet WAN port, using the new router to connect to the ADSL. Bingo it works. Plug the ADSL directly into my old router and it does not. Same config. Same port forwarding\blocking configuration. So what could it be? I can't continue with the lashup of the two routers but I can't for the life of me work out why the VSS stopped working with the Draytek. Was there some sort of firmware update a few weeks back to the VSS so it now hates my old router? Any help appreciated.

Hi @LeeJS,

Unfortunately my ISP does not support my router, it's my router. I agree though it seems like the router. I guess that has always been obvious to me and I was hoping that someone in the eForum might have a flash of inspiration as to why a perfectly functioning router (in all other respects) might suddenly stop a VSS from working. It's the kind of problem which can only be sorted by a group of people who may have experienced similar themselves and someone can say "Yes that happened to me and in the end it was this ....!". 

Of course Vodafone is my ISP (since you bought Demon). But they have zero chance of fixing this if I am honest. I will however ask but suspect they will just blame my router and wash their hands of the problem. And they have a disadvantage in that they won't know what a VSS is and will probably tell me to talk to you.

So I will continue to investigate on my own but at least this thread is here and one day someone might stumble across it and have the answer. And .. if I fix it I will be sure to post the cause here.

Thanks all for your various efforts.

John.
