I’d go with an AC card, it will work better than an N only, even though your routers are all N only. There’s a good list of supported WiFi adapters on the raspberry pi site with links to amazon you might check out. Most are type N and a few are dual band like you want.

Hello,
My networking equipment, routers, and the like, are n, not AC and I don't have the budget to update them at the moment, that's why I'm looking for a dual frequency n USB card.
Thanks. Dave.

So 802.11AC is basically using a higher density quad modulation scheme as well as functions on the 5 GHZ band for more literal bandwidth. Another feature is beam forming which allows the signal to bar focused rather than just radiated in all directions. You can use AC adapters on N routers although when possible you should upgrade to AC if you can. I’m all AC now on my home network and it’s working very very well.

Hi,
Thanks. I'm seeing a lot of cards on amazon that are 802.11AC what is that?
Should I go with AC or N? I only have N networking equipment.
Thanks. Dave.

It might be worth looking for a device that supports HostAP mode (i.e., it can operate as a wireless access point, if necessary). When I last checked (some years ago), Atheros-based cards could do this, but I'm sure they're not alone.
