I've got a RT-N66U and RT-AC66U router.
I'm currently only using the AC one with stock firmware (latest to date)
I'm wondering with the current Asus hardware that is out there whether it is worth selling both of them and upgrading to something better and if so, what would you recommend?
I don't have a lot of issues with the AC66U other than the 5ghz band can be a little flaky when using it with my 2013 Retina Macbook Pro but I think it's the Macbook not the router as other AC clients work ok.
Also the coverage is not quite full using 5Ghz band to a back room but ok everywhere else.
Not sure what else to add other than I just want something that would improve the 5Ghz range and help keep up with current hardware as I don't want to upgrade later when the current routers are worth nothing second hand. At least now I can get a good price for them here in NZ to put towards a new router.

Any help or opinions would be appreciated. Happy to answer any further questions about my current network environment.
