Yup, that one's not the "best" available, but it's of the latest generation of products with good speed and range, so good value for money.
I've never had a problem with setups as I have a techie background, so my opinion on ease of use is probably not the best to go by as I think they're all easy to setup
But they all come with "wizards" these days to assist with setup, plus Linksys have a good amount of support resources on their website:

Personally, I wouldn't think you'd have any trouble, but perhaps a non-techie person here with experience of Linksys products could venture an opinion?
