I'm looking for opinions here, ideally with brief supporting anecdotes.
ASUS RT-N16 router died for the second time in 5 years. They are cheap, though. A replacement could be had for $83. Given the failure rate so far, I'm leaning against this.
I'm considering an ASUS AC66U or AC68U and wondering if the AC68U is worth the extra $50 or so.
I'm also considering DD-WRT, with which I am familiar, or TomatoUSB/Shibby which is reputed to have better performance on 5Ghz bands. I value security the most, with performance and ease of use tied for second.
