Greek? or Geek? LOL
Well, it has been an educational experience, though unfortunately I'm not sure what I learned!
I guess that 2.4 is faster and crisper, but the wavelength is shorter and the 'width' of coverage is not as great.
I ended up getting a Belkin b/g router that somehow is meant to offer greater speed (125mbs) somehow, but I couldn't quite figure out how. If I get anywhere close to 56mbs I'll be happy.
The main thing is I got all the computers set up and online and secured, and internet connection is fantastic. But I couldn't' actually get them networked together just yet, i.e., sharing files and printer. It seems I need to use an USB flash thing to do that easily.
Belkin had yet another router with something called "Pre-N" that is meant to increase coverage area by 600 percent and speed by a staggering number, (if your other devices are also "Pre-N"), but it was a lot more money. I'm hoping my client will be able to access their one laptop from a more distant location with router I purchased. I'll try it in the next couple days. But so far so good.
