My customer has a G class router, 54mbs download. He parks his laptop right next to it and uses the wireless. In terms of speed alone (not the security of wired versus wireless) I think it would be better if he used an ethernet connection. But when I do a speedtest I get the same output either way. This also gets into the question of whether an N router is any better than a G. Time Warner Cable gives the customer 15mbs download and 1.2 upload. If a G runs at 54mbs download, why would that be better than an N router, which costs more? How can it go faster than what Time Warner sends to the modem? It's the same issue with the ethernet router speed. It may say we're getting 100MBs download, but how can the router stream any faster than the line going into it? And why would gigabyte ethernet be any faster than 100mbs? I don't know if it's relevant, but the customer has a Dell Latitiude E6420 running Win7 Pro 64bit.
