To add to the review issues. They have two selectable boxes in the Specifications section re the band types one is the 802.11n/ac and the other is 802.11ac. Now it doesn’t quite make sense why you would tick either of these boxes as the 802.11ac routers all have 2.4 Ghz and 5 Ghz and the 802.11n/ac also share this but the selection just removes some from either result listing. If some are purely 802.11n or if some are 802.11a (and not 802.11ac) I could understand why you would have the selection boxes and they would need to be properly labeled but as currently setup it is just confusing.
Being able to select whether tri band or dual band would also be helpful and whether just MIMO or MU-MIMO, or beamforming (though most if under “ac” specs should be beamforming) or not would also be useful as choices. Whether they have VPN abilities built in, what RAM (useful when multiple connections) are also nice bits of info to have or to be able to more finely select on.
Antennas that are replaceable or not, whether some also have internal as well as external, what gain they are are also useful bits of info but this is not always important.
