One moment you’re dominating the latest online game while streaming a movie, but the next you can barely load a simple website. Maybe the connection is worse on one device or in a particular part of the house.

You can’t seem to get full internet speed through your router. If you rely on Wi-Fi for your home network, then it’s important to optimize it as much as possible and make your Wi-Fi faster.

1. Test Your Internet Connection

Before investigating your Wi-Fi network, you should rule out whether the problem lies with your Internet Service Provider (ISP).

If you have a laptop, computer, or games console, test your internet connection by plugging your device directly into the router with an Ethernet cable.

Using this setup, if the internet still doesn’t work, then it’s likely a problem with your ISP. Many providers can perform remote diagnostics, so it’s worth contacting their support team to try and get to the bottom of the issue. However, if the internet works then, you may have a problem with your Wi-Fi network.

If you were trying to access a particular website, use a site like IsUp.me to see if the website is down for everyone or just you. While still connected via an ethernet cable, run a speed test How to Test Your Wi-Fi Speed (And 7 Mistakes You Should Avoid) How to Test Your Wi-Fi Speed (And 7 Mistakes You Should Avoid) Wi-Fi speed tests can tell you how fast your wireless speed is. These tips will help you check Wi-Fi speed accurately. Read More .

This will help you get an idea of the average Wi-Fi download speeds you should be getting on your network. Keep in mind that cabled connections will have higher speeds, so you should expect a small drop on Wi-Fi connected devices.

2. Update Your Firmware

As with other areas of your digital life, you should ensure that your router’s firmware is up-to-date. Along with essential security patches, these updates often come with many bug fixes which can make your Wi-Fi speed faster solve all connection issues.

Make sure to update your firmware before diving into any further troubleshooting, as it may save you hours of fruitless work. If you were already running the latest firmware, then reboot the router to clear the cache and reset the software.

3. Switch Wi-Fi Channels

Wi-Fi networks broadcast on many different channels and two separate frequency bands. In the US, there are 11 standard Wi-Fi channels, while worldwide there are usually 13. In the early days of wireless networking, routers only broadcast on at 2.4 GHz.

However, as more of us have come to have home Wi-Fi networks the amount of channels has needed to expand. Many modern routers can now broadcast at either 2.4GHz or 5GHz.

While this gives you more options, it’s always possible that another nearby Wi-Fi network or other electrical equipment is already broadcasting at your network’s frequency. Overcrowding a particular frequency may cause your network to slow down, and could be the root of your Wi-Fi problems.

To rule this out, make sure you pick the best Wi-FI channel for your router.

4. Check Bandwidth Consumption

If you find that your Wi-Fi speeds drop periodically or at certain times of day, then it’s possible software or other devices are eating away at your bandwidth. Large downloads, video streaming, or online gaming can be bandwidth-hogs so check for these first.

Check and troubleshoot what is using your bandwidth with these tips. Read More directly from the router or a third party program. Delving into your router’s settings should let you find out which devices are connected to your network. If there are any you don’t recognize, then you should remove them.

Malware could also be to blame for your slow speeds, so be sure enable protection and run an antivirus scan.

5. Optimize Wi-Fi Router Placement

When first setting up your network, the position of your router is probably one of the last things on your mind. However, the environment around your router can cause a significant impact on the quality of your Wi-Fi network.

Although we can’t see them, wireless signals are passing all around us, but they can get slowed down or, in some cases, blocked entirely. Concrete and metal are so effective at blocking wireless signals that they are even used in Faraday cages.

So, if your router is in your concrete-walled basement, you should move it elsewhere in the house. You should also try to position the router in the center your home. Wi-Fi signals broadcast in 360 degrees, so it doesn’t need to be at one end of the house to get the best coverage.

6. Tighten Your Network’s Security

During your investigations, you may have found suspicious devices connected to your network. Although you’ll have removed them, they suggest that someone has gained unauthorized access to your Wi-Fi network.

This could be something an innocuous as a neighbor leeching off your network, down to something far more threatening.

There are plenty of ways to configure your router to make your home network really secure How to Configure Your Router to Make Your Home Network Really Secure How to Configure Your Router to Make Your Home Network Really Secure Default router settings put your network at risk, allowing freeloading strangers to squeeze nadwidth and potentially commit crimes. Use our summary to configure your standard router settings to prevent unauthorized access to your network. Read More . However, at a minimum, you should change your router’s default admin login. This is often set to user: admin and password: password. Because nearly every router uses these default credentials, they are easy to exploit.

You should also ensure that your Wi-Fi network is secured with a wireless password. Most routers have this enabled by default with the password stuck somewhere on the device itself.

However, if you want to change this, log in to your router with your newly created credentials, and you can manually set a new wireless password.

7. Upgrade Old Router Hardware

If you’ve had the same router for more than a few years, it may be time to consider an upgrade to boost your Wi-Fi signal. Fortunately, you don’t have to spend considerable sums to see a dramatic improvement.

One of the easiest is to upgrade your router’s antenna. Most routers come fitted with standard antennas that only have a limited range. You can buy an aftermarket antenna for as low as $10, so it doesn’t have to put a strain on your bank balance either.

    I wish I could figure out why our laptop is suddenly losing internet connection. I've done allowed the updates and still it drops Internet, while remaining connected to the router. We have to physically walk the laptop to the router where it connects again and is usable back in the family room for awhile, until it drops again. It is connected to the 2.4ghz band and the only device on it. All other devices are on the 5ghz and work well, with no internet loss. The laptop has only 2.4 capability. I've used a wifi analyzer and there really seems to be very little drop in signal throughout the house. I've done speed tests. With the desktop connected via Ethernet to the router, I get good ping and speeds. With the iPad on 5ghz wifi, it is slower and jerky, showing drops to nothing and then back up several times during the test.
    Does this sound like a router issue? It's just over a year old. Belkin N600. Thanks.

    went though many of the step in you article and thanks for all the info. However, even though working with all the info I jumped my wifi from 1meg dn to 4meg dn. I was thinking I needed to replace my old router. But decided to try one last thing, I blew the router out with canned air.
    The down load speed jumped to 25megs down. So don't forget cleaning, sometimes it works wonders!

    My question is how can I set my router so that it gets closer to the 105 mbps download speed I am paying for. With a direct connection to the modem, it pulls 105+. Once I switch to Wi Fi only, it only gets around 25 to 26 mbps. Is there a setting which will allow a faster speed?

      Could be your wireless card or wireless adapter you're using. Might be slow or old. Try purchasing a gigabit network adapter and using it. I max out my connection

    We used to have bad wifi signals because our wifi setup was far from where the room we usually do the wireless internet surfing and all the walls blocking. But we recently changed the place of our wifi and did a DIY windsurfer from youtube tutorials cantenna is also effective but my mom preferred the windsurfer and it did a good job we get the maximize wifi full bar signals. Another thing we used a name of a virus for our wifi so neighbors wouldnt even dare do piggybacking or leeching. Our internet connection problem though is our provider themselves because of the poor service they give not the wifi router's fault. But I would do the checking of wth is eating my bandwidth. XD

    "Of course, MAC address filtering is time consuming and therefore not ideal if you have guests visiting regularly."
    If by "guests visiting regularly" you mean the same guests repeatedly, then you should add them to your white list. That's what I do. I have added the two or three people who visit us regularly to my white list.

    If by "guests visiting regularly" you mean a steady stream of different guests, such as the student body of the nearby state university, then maybe you should set up a separate network for their use. /grin/

    Modem connected to router, WiFi works
    Modem connected to desktop, connection works
    But when modem is connected to router which is connected to desktop, no connection. Earlier it used to be fine. Why is it happening so?

      If you have Tomato or DD-WRT it's not too difficult to setup a guest wireless network that's isolated from your regular network. You setup a VLAN for guests and one for your regular network and ensure both have internet access and can't communicate. There are guides online and one should theoretically work for both firmwares if it's based off cli commands.

      How do you know that WiFi works when the router is connected to the modem? Wouldn't that be connecting your desktop to the router? Because otherwise you might have some strange issue with your Ethernet.

      Hi Danny S, I will explain: I have a modem- connected to router- router connected to desktop; with this set up my home was Wifi and the desktop had the wired connection. It used to work well until recently when "ethernet" light on the modem stopped glowing with this connection and both wifi and wired connection was disrupted. I tried giving a direct connection from modem to desktop, the wired connection worked well. Then I disconnected the desktop and tried with the modem connected to router and my home was wifi again. But when I try to establish both wifi and wired connection as I was doing all this time, the ethernet light wont glow and both wifi and wired connections are lost.

    • Oron J

      If the ethernet light on your router has stopped shining, there's a problem in wired connection between the router and the modem. It could be a fault with the modem or router, but most often it is the cable. Get a cable that you have tested elsewhere and know to be working, and use it. If everything works, problem solved. If not, test the router and the modem separately (against the PC), and identify the culprit.

      Thanks Oron J, checked the cable, its working fine...have to test both the modem and the router now.
