Anyone having a problem with their Vodafone at home broadband of late?

My t'interweb is playing up to an incredibly annoying degree, with the DSL sync light dropping out regularly, and staying annoyingly intermittent for long stretches of time.
Today for example, couldn't get a steady signal today from 1 to about 3pm, eventually gave up and went to the folks' (so no issue with the laptop's internal doodads I'd guess) to get my stuff done. Back this evening, and only now got a steady light after about half an hour of flashing, and from the experience of the last few days it could go again at any second.

Netopia (former Eircom) box, and a user that wouldn't be very much more clued in than to know that.
Anything simple I can do? All help greatly appreciated!
