O Canada! > Canadian > Canadian Broadband > Looking for some router recommendations

Consider that if your router is not capable of simultaneous N and G, it'll be effectively locked to one or the other permanently. In practice, especially when comparing 5 GHz N to 2.4GHz G (you always want to run 802.11n on 5 GHz if possible due to the much greater spectrum available), you're not going to log into your router and reconfigure it, cutting off all your 5 GHz devices, just to occasionally play your wii.

I always understood that the router would just drop the N to G automatically if it detected a G device connecting, and then go back to N afterwards.
