Been using a WRT54G but it just died on me should i just buy another one? I would like to get a N router but i still have devices that use B so if i bought N wouldn't it just run in mixed mode so i wouldn't be able to take advantage of N speed? I was looking at buying a ASUS RT-N16. (don't really need the USB) But i'm thinking i should just buy another WRT54G and a cheap N access point so i can get the best of both worlds. Suggestions?
