I want to ask a simple question: Is Wireless N backward compatible with older wireless technologies such as G?
My current router has been dying on me for a while and all the network equipment in my house is for G such as PCI cards and a access point, so if I bought a N router, would I still be able to connect using a wireless G PCI card?
I'll clarify my point - An adapter that's only G or B/G-capable, will not connect to an N-only network. However, most N-routers on the market allow mixed mode, as many older wireless adapters and even newer cell-phones only have 802.11G connectivity.
Before anyone can make a recommendation on that count, you have to offer more specifics, such as:
1) Is there a lot of interference in the area (population density, microwaves, cordless phones)? Bad for 2.4GHz
2) How many walls will your signal have to get through? Bad for 5GHz
3) What exactly do you wanna use that router for?
4) What is your budget?
5) Which wireless chipsets do the adapters on the most critical clients have?
In any case, I wouldn't recommend wireless for anything other than casual Internet access. If you wanna transfer a lot of data over the local network, get a drywall saw, fish-tape, a spool of Cat6, mud, knife and a sanding sponge. Take one of your cutouts (has to be about 2x2") to the hardware store to get your paint color-matched in order to touch up your work (assuming you don't just repaint everything).
