Not big improvement over G router, but worth what it cost.
7 February 2013
Summary: Had Linksys G router (5-6 years old) and thought that advances in N would help improve reception throughout the house (G router gave spotty performance on upper floor). Improvement in performance was minor, but did make a slight improvement in signal strength in the rest of the house. Don't know if lack of external antenna is a benefit (old one had them). Glad I didn't buy one new and paid more than it was worth.
