Fritz Router 7490 v 7530

Hi,

So 2Degrees has just sent me a Fritz 7530 to replace my 7490.

I'm not sure what I was expecting to see, but cant really tell if there is any difference at all.

I was hoping for better coverage around my house and out to the garage using the 7530, but it appears the same.

Is one better than the other? - or just the same.?

Thanks
