I'm looking at the settings on my new router, and noticing that I can choose the modes it supports, such as b/g/n vs just g/n, and a/n/ac vs just n/ac. Since my laptop, phone, printer, TV, etc. all support the newer standards and don't need 11a or 11b, I'm wondering if there's any benefit to disabling support for the older stuff on my router -- perhaps the backwards compatibility incurs some unnecessary overhead, for example?
