Hi, Please forgive my lack of knowledge on this, and I've tried searching for this info as well... I have an Airport Extreme Wireless N Network that I am using. I'm not sure if I remember correctly, but if I connect a wireless g device to it, will the network use the slower speed? To be specific, I have to connect an older T-Mobile Hotspot@Home Wireless G Router that I have never opened (finally need the home number service). I'm concerned that because of the wireless G, my network will run at G speeds, at not N. Is that correct? How can I fix this to make sure that everything is at the proper/fastest speeds? Thanks so much!
