No, but it's DSL based, so you would think they'd all be the same - possibly naive in saying that. In any case, I use BT and am not moving to Talk Talk, even though I use them for phone - as they give it free to customers in the UK...so I'm not budging till it's free here I actually think it's quite expensive, not sure it's better value than BT either.
I can't seem to find any infoon it being released in ireland, unless you're in the UK yourself?
tbh, I would go for another, more reputable source as wireless internet from talktalk might only be in the test phase (?).
