Wi-Fi is everywhere these days. Many homes come with Wi-Fi capabilities as standard extra features. But while technology has advanced heavily in the past couple of decades, it doesn’t mean we have unlimited wireless signal reach in our homes. Sometimes our network signal can refuse to reach certain areas, even rooms.
So how can we improve our Wi-Fi signal? Here are ten strategies (plus a few bonus ones) on how to extend your Wi-Fi signal (or troubleshoot any Wi-Fi connectivity problems) that will ensure you’re getting the best Wi-Fi service you can for your home.
Before spending your hard-earned money on new Wi-Fi equipment, you want to make sure you can get the most value from the equipment you already have. Below are some ways to quickly boost and stabilize your Wi-Fi connection and eliminate dead zones without spending a dime.
If your wireless network isn’t getting the speeds you paid for, it may not be the fault of the Wi-Fi router. The problem may be with the modem. Check your modem by plugging an ethernet cable directly into one of your modem’s gigabit ethernet ports and your computer and running a speed test.
If the modem runs fine at this point, do the speed test wirelessly by unplugging the ethernet cable from the ethernet port and standing next to the modem while you’re doing the test. If the test does poorly at this point, you may need to upgrade your Wi-Fi router. If the test does well when you’re standing next to the router, but you get a poor signal in other parts of your home, you may need to extend your existing wireless signal using a Wi-Fi repeater.
Another culprit of weak Wi-Fi signal or dead zones may be outdated wireless router firmware. Router manufacturers are always looking for ways to squeeze more speed from their hardware, so keep your router’s firmware current to ensure you get reliable Wi-Fi signal and speeds.
Most routers take care of updates automatically or make the process as streamlined as possible. Regardless of how tedious the process is, or even if you don’t suffer from poor Wi-Fi speeds, you will still want to update your router’s firmware to ensure improved speeds, security and added security features.
Where you physically place your router in your home can significantly impact your Wi-Fi coverage. You may want to put your router inside a cabinet with a hole to run your cables, but doing so will hamper your Wi-Fi signal. If you only have problems getting a signal in select areas of your home, all you might need to do is move your router. Make sure the router is in as central of a location as possible.
Other nearby electronics and heavy-duty appliances can interfere with your Wi-Fi signal if they are too close to your router. To get the best signal, move your router away from all obstructions. You want to place your router in an open space. Ideally, your router will have an uninterrupted line of sight to your device. Putting the router in an elevated area, such as a shelf, will also extend Wi-Fi coverage.
If your router comes with moveable external antennas, aim them toward the sky to boost coverage.
If you’re experiencing interference, you could be sharing a channel with other Wi-Fi networks that use the same channel. Most routers automatically select a channel with the least congestion, but older routers will use a predetermined channel, rarely the best option.
Check if your router may be competing with other networks for the same channel. If this is the case, change the channel to a less congested one. Your signal should improve significantly.
You can find out which channels are being used by going to your command prompt and entering “netsh wlan show all.” This command will list out all wireless networks in your area and the channels they’re using. Alternatively, you can use a Wi-Fi analyzer to survey your existing Wi-Fi network and other nearby networks in an easier-to-read graphical format.
Channel congestion can change over time, so you want to manually check to see if your channel is more congested than before. If so, you can switch to a different channel and see a noticeable spike in Wi-Fi network performance.
QoS (Quality of Service) services, supported by most modern routers, will let you prioritize certain apps over others.
Here’s how to change your router’s QoS settings:
Some settings may differ depending on your router. Consult your manufacturer with any questions you have about accessing your QoS settings.
Wi-Fi routers generally support two bands (2.4GHz and 5GHz.) The 2.4GHz band is slower, but it can pass through obstructions much better than the 5GHz band. If you’re in a smaller home, such as an apartment, a 5GHz band should work perfectly. If you live in a large home or are trying to get a Wi-Fi signal outdoors, you may want to switch to the 2.4GHz band. You will sacrifice some speed, but you’ll get a much more stable connection with a signal that can more readily pass through obstacles.
Most routers manufactured today off the option to use both bands on the same network name (also known as an SSID.) Look at your router’s admin interface and look for the 5GHz option. Give the 5GHz network the same SSID and password as your 2.4GHz network. The router should automatically choose the best signal.
If your router doesn’t have this option, give your 5GHz network another SSID and password, then connect to that one manually.
If you have an open network, or if your network uses a weak password, you are almost guaranteed to have some uninvited guests taking up bandwidth on your network.
If you’re running Windows, you can use a free tool called Wireless Network Watcher to download a list of all devices on your network. There are some advanced items on the list you get back, like IP address, MAC address, etc. You can safely ignore those items and pay attention to the “Device Name” and “Network Adapter Company” columns to see which devices don’t belong on your network.
If you spot intruders and need to kick them off your network, you can go to your router’s web interface and change your network’s password. Keep in mind that once you change your network’s password, this will boot ALL of your devices from the network. If you have many smart devices you use around the house, you’ll need to update the password on every device. However, keeping your network secure is worth the relatively minor inconvenience.
Like all tech that relies on software, sometimes rebooting the device may solve whatever problems you’re experiencing. Rebooting will clear out the router’s memory and allow it to install necessary updates. The simplest way to reboot your Wi-Fi router is to unplug it, wait about one minute, then plug it back in. Rebooting your router can take a long time, so you need to be patient. If your router installs an update during its reboot cycle, the entire process can take up to 10 minutes or more.
The Domain Name System (or DNS) converts domain names into numbered IP addresses. Your service provider will set up your modem to use its DNS server by default, which may not give you the best performance. However, most modems will let you change your DNS address to one that is much faster. This method is the easiest way to boost Wi-Fi performance. You have many public DNS servers to choose from, including heavy hitters like Google and Cloudflare.
To find the best DNS server in your, download and run a free Windows app called Domain Name Speed Benchmark. Once you open the app, switch over to the “Nameservers” tab, then click “Run Benchmark” Once the app finishes its process, click on the “Conclusions” tab to get your results. Once you see the best DNS server for your area, go to your modem’s settings and replace the default DNS address with the new server’s DNS address.
Technology can glitch out at many points, and some of them won’t originate in your home. It can be frustrating to experience a signal loss or even have your network shut down entirely. Still, downtime could result from a planned maintenance period, some software that glitched on the ISP’s end and similar tech issues plaguing home networks.
Before you potentially waste your time tearing your network apart to find a problem that might not be there, contact your ISP to see if any issues are popping up on their end. Your ISP will be able to see what’s happening on your Wi-Fi network and troubleshoot on their end. They can also send over a technician if they can’t solve your connectivity issues over the phone.
Even with the methods above, you will inevitably run into a situation where you will need to get rid of your current router and purchase new equipment to boost your Wi-Fi range and use newer technology to improve its stability and speeds. Get these tools to get seamless Wi-Fi coverage in ways you can’t do with software alone.
Many Wi-Fi routers don’t have enough antennas to provide Wi-Fi coverage for large homes, making your home’s Wi-Fi signal weak. Depending on the existing router type, you may not be able to adjust the router’s settings.
Some routers don’t have antennas, so you may need to add an external Wi-Fi antenna to your router. An external Wi-Fi antenna could be as simple as a Wi-Fi repeater or as complex as a MIMO (Multiple-In Multiple-Out) system.
Many routers come with USB Wi-Fi adapters that you can use to extend the router’s signal indoors. These adapters will help provide faster internet to floors and rooms that your router may not be able to reach.
Make sure you’re also using a router that supports the latest technologies. As of this writing, IEEE 802.11ac offers the fastest download and upload speeds compared to older technologies like IEEE 802.11b.
When grabbing a new modem, you don’t want to get the cheapest router available, even if it does support the latest technologies. Ensure the new router you’re buying has the range you need and all your required features. Make sure the devices you use to access your Wi-Fi network also support these updated technologies.
Using an additional wireless router, a Wi-Fi extender, or a Wi-Fi repeater, extends the reach of the original signal. A Wi-Fi range extender can be easier to set up and solve the signal reach problem for you just as quickly. However, if you need to cover a large area, you may need a different type of Wi-Fi extender, such as mesh Wi-Fi networks.
Wi-Fi range extenders come in different styles. With some of these Wi-Fi extenders or Wi-Fi repeaters, all you need to do is plug them into an electrical outlet to extend the reach of your existing Wi-Fi signal.
The best places to employ a mesh network system are areas of up to 1,000 square feet in a single- or multi-floor building. A mesh network will easily be your best option if a typical Wi-Fi extender or Wi-Fi repeater doesn’t provide the coverage you need. A mesh network is simple to set up and will significantly extend your wireless signal in no time.
With how many new connected devices we have in our homes nowadays, your current internet plan may not be able to cope with each of them consuming your bandwidth. If you’ve recently purchased smart devices over the years, you may need to upgrade your internet plan. Contact your internet provider and see what plans they have available.
