An 11n AP will give you the exact same performance for b/g clients as a b/g only AP and is supposed to give you more speed and more range for 11n clients. So, it's all down to how much you want to spend
I understand with B/G device but the macbook laptop has N network. Will it drop to B/G speed and range too ? or it will be on N speed and range ?
I'm in a similar situation. My parents' G router needs to be replaced and for the most part all devices are G, yet some are N. From what I've seen it seems to be that any G devices would cause the N device(s) to drop to the G speed.
I'm a little confused on this one, so hopefully someone else can reply and clear this up. Previously, I've used a B device and G device on a G router. The B ran at 11mbps and G device at 54. I would have expected N to be the same with a router that is N, however I've read things that lead me otherwise.
Right now I'm debating whether or not to get them a G router or N. If an N router will run everything at G speeds because there are G devices then I don't see much of a point to get N.
