Vodafone SureSignal problem on Slingshot

Just happened to notice orange lights on my Vodafone SureSignal v3. Solid red power light and the rest were solid orange. Manual says:

Failed to authenticate with PPPoE ISP. Where customer has locally configured unit to PPPoE, to be compatible with local ISP

Tried to power cycle the unit and now it just won't connect. Fails to get past the pulsing white (2nd) light which indicates negotiating a connection.

Anyone else having problems?

Also unsure if this is something to raise with Slingshot or Vodafone.

Thanks
