So today I am sitting in a local eatery which offers great food and free WiFi and a few of the customers are whining to the manager about their Wifi at home being slow and how wonderful it was that they got a new router.
As I listened and said nothing, I heard the restaurant manager bragging about how the place was getting a 10gb/sec fiber connection. Sure, that does mean he will have plenty of bandwidth to use. Of course there are other factors to look at. It’s okay, I see your confused looks, but worry not about the gigabits, or megabits, we are going to look at this in simple terms like hoses and water.
So if you have a firehose that’s 10 inches in diameter hooked up to your house, will the shower actually pass more water through, assuming the pressure is the same? The answer is no, because the pipe to the shower isn’t the same diameter (gb/sec) as the firehose! So what would be the limiting factor on your network? Actually 2 things. The speed that your wireless router, which plugs into the network (the giant hose) runs at and the speed your device can communicate with the the WiFi router.
So let us assume that your router can actually achieve a 10 gb/sec connect with the Internet (the big firehose), but in the real world, on the WiFi end, most devices are lucky to connect to that router through wireless at much more than 50-150 mb/sec. So assuming your laptop or smartphone is connected to the WiFi at say 75 mb/sec and the router is connected at the full 10 gb/sec, what is the fastest speed you will ever see on you device? Why yes, it is 75mb/sec because that is the slowest point of the connection and just like water it doesn’t change.
By the same token if you purchase a 300 mb/sec WiFi router and plug it into your cable or any other provider modem and you are connected to that router at say 150 mb/sec, but your Internet provider is only running at 50 mb/sec what will the fastest speed you ever acheive be? Why yes, it is 50 mb/sec and not one bit more. The weakest/slowest link in the chain is what determines your speed.
Got it? No? Think of it this way, if you hook a garden hose to a fire hydrant, will it pass less water than a firehose? Yeah, it’s like that.
