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. If it's manual, I guess I would be better off getting a simultaneous one then.
Are the TP Link WDR series good overall? Hardware wise, the 3600 and 4300 seem to fit what I would need and the prices are decent.
