All About Wi-Fi: Common Wi-Fi Questions Answered

Wi-Fi connects us through so many devices, it’s not unreasonable to have a few questions about the wireless technology. Where did it come from and how exactly does it work? In this guide, we’ll take a look at some of the most pressing questions about Wi-Fi.

What is Wi-Fi?

Wi-Fi is a wireless network technology that allows devices to communicate on specific wireless frequencies. It’s based on the IEEE 802.11 standard and is one of the most common forms of wireless support available today.

What is Wi-Fi short for?

Wi-Fi is short for «wireless fidelity». The official way to spell the term is «Wi-Fi», as confirmed by the Wi-Fi Alliance.

Who invented Wi-Fi?

ALOHAnet is one of the earliest reported cases of wireless network support, using wireless ultra-high frequency (UHF) bands in the early 1970’s to transmit network packets between islands in Hawaii. This system is regarded as one of the earliest precursors to modern Wi-Fi.

Today, the modern Wi-Fi standard is maintained by the Wi-Fi Alliance, an organization that determines terms and parameters for today’s Wi-Fi technology.

How does Wi-Fi work?

Wi-Fi uses predetermined frequency bands to connect devices so they can transmit data packets between each other wirelessly. Networks require a wireless router to create a Wi-Fi network. Devices must be within a specific physical range of the router to maintain the wireless connection.

How do I connect to Wi-Fi?

If you want to connect to Wi-Fi, you will need a device capable of wireless connection. Most devices have network options under the settings screen.

You will need to know the name of the network as well as any required passwords to connect.

How do I share a Wi-Fi password?

Wi-Fi passwords are nothing more than a string of characters. You can transmit the password via text, email, verbally, or even via writing. If you want to transmit the password with a little more security, you can always opt to transfer the Wi-Fi password between smartphones.

How do I boost Wi-Fi signal?

Wi-Fi signal strength is determined by the wireless router. If you aren’t getting enough signal, you may want to use a signal booster to increase the wireless support range. Check out our guide on how to boost your Wi-Fi signal.

How do Wi-Fi extenders work?

Wi-Fi extenders or boosters are devices that connect to your router to increase the physical range in which devices can connect to your Wi-Fi network.

Am I connected to Wi-Fi?

Check the network settings on your device. Make sure wireless is enabled. Look for a list of available Wi-Fi networks, you should see an indicator for whichever network you’re connected to.

How do I find my Wi-Fi password?

Your Wi-Fi password may be provided to you by your ISP. If you aren’t sure what it is, you can always use your router to set a new password. Check out our guide on how to find your Wi-Fi password.

How do I change my Wi-Fi password?

Access your router using its IP address and a browser window. Log in to the admin account on your router. Look for wireless network settings. You can set a new password in the network key field. It may be labeled PSK.

How can I get free Wi-Fi?

There are several ways to get access to free Wi-Fi. The easiest way is to find a business where free wireless is offered to patrons. Visit our guide on how to find free Wi-Fi for more tips.

What is Wi-Fi calling?

Wi-Fi calling allows users to receive and make phone calls using Wi-Fi instead of the cellular network. This is extremely useful in areas with little to no service.

8 Frequently Asked Questions About Wi-Fi

What’s the difference between the Internet & Wi-Fi?

The Internet is connected networks all over the world. Wi-Fi is your personal wireless network within your home.

Why is a speed test not showing the speed I pay for?

There is a box (usually some type of modem) that brings Internet into your home from your service provider. The speed test should be run from that device in order to run a speed test against what you are paying for.

Why are my Internet speed tests slower when I’m on Wi-Fi?

Your testing speeds over Wi-Fi are impacted by many things, consider the following:

• What is the type and age of router you are using? An older router may not support the speed you subscribe to.

• Do you have the latest firmware (software) updated on your router? This is important for both performance and security.

• What is the maximum speed the device you’re using will support?

• Is there a chance you have a virus or malware on your device?

• Do you have other things running on your device when you’re running the speed test?

• And finally – how far are you from the wireless signal? Do you have a full signal?

All of these things may cause slower speed tests results over Wi-Fi.

How can I get the speed I pay for over my wireless device?

The best way is to have a router or gateway that supports the speed you pay then, make sure:

• you have the latest firmware on this device,

• the device you are using is capable of the subscribed speed,

• you do not have any viruses or malware running on your device,

• you close down all other applications before running the speed test, and

• you have full bars on your signal before running the test.

All of these things may cause slower speed tests results over Wi-Fi.

Why can’t I get a good signal in my bedroom?

The wireless radios in your router/gateway push service out from the device. Think about it like a speaker, the further you get away, the softer the sound is. Your Wi-Fi works the same way. The further away you get, the weaker the signal. If there are things like metal, concrete, thick walls, and mirrors, between you and the router these can weaken the signal even more.

To learn more about household items and features that can effect your signal, read our previous article here.

How can I get a better signal on my patio?

The placement of your router or gateway determines where the Wi-Fi signals are strongest in your home, or outside your home. The more centrally located, the more of your home it will reach. However, you can add extenders to push the signal further into other areas of your home if your router or gateway is in a location where it can’t be moved.

Why should I buy Managed Wi-Fi?

The best thing about Managed Wi-Fi is that we take care of it. You don’t have to try and select the right kind of router, you don’t have to worry about updating firmware – we make sure it supports the latest devices, the fastest speeds and help to keep your Wi-Fi secure. We will help you place it in an area that maximizes coverage throughout your home. If you ever have any problems, we take care of it.

If you are interested in learning more about why you should give Managed Wi-Fi a try, check out our previous article here.

What if after that I still can’t get a signal everywhere?

Netsync IT Services can easily add a mesh extender to make sure all areas of your home are covered if you need the router in a specific location and do not want to move it. Some homes are just too big for a normal router signal and will need the mesh device to get signal to all areas.
