Is 802.11n-only mode better than mixed mode?

I just realized that I haven't had any 802.11g devices for quite a while now, but never got around to changing my router settings. Would there be any benefit in changing the setting now?

 

There wouldn't be much benefit. See here for more info.

Basically, g-devices will slow down the network if they are active and the bandwidth is saturated. The g-device will have to transfer at the slower g-rate, and the effective bandwidth of all devices is reduced. Since you don't have any g-devices anyway, mixed mode and n-only are equivalent in performance.

 

If you have no "g" devices at all there's no point running it in mixed mode anyway.
Some sources claim that other claim something else but overall you have no reason whatsoever to run mixed mode so you may very well switch to "n-only".

Worst case scenario would be that nothing changes.

 

My router in my apartment (Cisco E1000) doesn't notice much of a difference between g+n and n for my devices (all n), though I leave it on n whenever it's at the house (not support to have routers at campus, so there I just use it as a switch).

 

Neither does my cousins Cisco E1000. A difference between 1-2mb in upload on g
