Best dual band wifi router (to replace Sky router)

Hi,

I'm looking to replace my standard Sky router with a better one due to problems with lack of range and frequent disconnects even when in full signal range.

I don't care about Sky's T&C's and have extracted username and password etc.

I just wanted some advice on which one to go for (cost isn't too much of a factor).

I beleive I should go for dual band?

I believe Netgear are the easiest to set up - is this a fair comment?

Is there anything else I need to take into account when choosing one?

And can anyone offer reccomendations as to the best ones for my purposes?

Thanks,
Alan
