In my house I currently have the WRT54GL wireless router.
The devices I have are
WIRED through router:
Windows 7 Desktop
WIRELESS through router
IPhone 5 (wireless n)
Vizio smart TV (wireless n)
Windows 8 laptop (wireless n)
Now the smart TV we just got, and the laptop is being shipped now. So my question is, should I look into a wireless n router? Both te smart tv and the laptop will be used most, especially for streaming and downloading. My internet provider is Time Warner Cable @ 15/1mbps
Granted, I know wirelss G handles up to 54mbps, but will wireless N help when streaming over wireless? What about dual band? If I should get the wireless N, should I use the 5GHz range?
N runs at faster speeds, but in my experience it does a somewhat poorer job at penetrating obstacles such as walls and ceilings, at least at the 5 Ghz frequencies, so the answer in part depends on how far apart your devices will be from the router, and how many obstacles will be between them.
Everything being equal, I would go for the N router over the G. I made the move a couple of years ago and have not regretted it. The biggest difference I have noticed is that when the device is within 30 or 40 feet of the router and few obstacles between, I get much faster speeds. So for a laptop in the same room or the next room, it's pretty much like having a wired connection.
