Come to think of it, I did have a nightmare getting it working in the first place…
My original network connection was an Apple Time Capsule used as a router, through a Vigor 120 ADSL MODEM to my (old) ISP. After much hair tearing, I had to replace the ADSL MODEM as it worked by accepting the PPPoE connection form the Time Capsule and translating this into PPPoA as used in the UK. (US use PPPoE). When I replaced the MODEM with another one that works in a different (but less convenient) way, the Sure Signal bounced into life.
Now, for the life of me, I could not work out why absolutely every other weird and wonderful protocol that I used, both initiated locally and remotely, would work with my old setup but the SureSignal would not. It just didn’t make sense and no-one at Vodafone really wanted to help.
Anyway, things have been working well for a long time – not noticed any outages although you are right – it could be off when I’m not here…
Vodafone in general has not been a great experience, I have to admit. I moved across from O2 when I got my second iPhone and kind of wished I didn’t now – not even visual voicemail works on Vodafone!!! Eh???
