Most routers ship with “safe” default settings, and that makes sense. Manufacturers want the whole setup process to be as simple and plug-and-play as possible. But those default settings aren’t always ideal. If you’ve spent hours researching which router to buy, you should definitely spend a few more minutes optimizing it.
Before you even plug in your new router, it’s crucial to understand that the default configuration is designed for mass-market compatibility, not for your specific needs. Every home network is different, and the one-size-fits-all approach can leave your network vulnerable or slow. Over the years, networking technology has evolved significantly, but many routers still ship with outdated defaults. By taking a few minutes to adjust these six settings, you can dramatically improve your online experience.
Turn off WPS
The outdated feature isn’t worth the risk
You may have noticed a WPS (or Wi-Fi Protected Setup) button on your router and never known what it’s for. Its main purpose is to let you connect devices to the network without entering that complex Wi-Fi password you’ve set. Yes, WPS sounds useful, which is also why it comes pre-enabled on most routers. But there’s one problem. WPS PIN authentication is vulnerable to brute-force attacks, which means attackers can also gain access to the network without knowing the Wi-Fi password. So if you never plan to use the WPS button to connect devices, it’s better to turn it off entirely.
The WPS protocol has been known to be insecure for years. In 2011, security researcher Stefan Viehböck demonstrated that the PIN-based method could be cracked in a matter of hours using brute-force techniques. Despite this, many router manufacturers continued to enable it by default. Even the push-button method, while more secure than the PIN, can be exploited if an attacker has physical access to the router. Disabling WPS in your router’s admin panel is a simple step that closes a significant security hole.
Use QoS to prioritize important devices
Make sure your gaming PC gets first dibs
By default, your router treats every device on the network equally. That seems fair, but it can also be a problem when one of your devices starts downloading large updates or backing up thousands of photos to the cloud and leaves other devices competing for bandwidth. Quality of Service (or QoS) helps you fix this. It basically lets you tell the router which devices should get priority, so your gaming PC or your phone never has to fight for bandwidth. Some routers can even prioritize certain types of traffic with QoS. For instance, you can set high priority for gaming and streaming while setting low or medium priority for web browsing and messaging.
QoS has been a feature on routers for years, but many users overlook it because they don’t understand how it works. Modern routers often include intuitive interfaces that let you drag and drop devices into priority tiers. If you have a mix of high-bandwidth activities like 4K streaming, video conferencing, and online gaming, QoS ensures that lag-sensitive applications get the resources they need. Without QoS, a background download on one device can cause buffering on another. By configuring QoS, you can maintain a smooth experience for everyone in the household, even during peak usage times.
Change Wi-Fi channel
Your neighbors could be slowing down your Wi-Fi
Most routers are configured to choose a Wi-Fi channel automatically, which usually works fine. But if you live in a congested area where a lot of your neighbors’ routers are doing the same, it can be a problem. When too many routers end up broadcasting on the same channel, it slows everything down. An easy way to avoid this is to pick a less crowded channel manually. The 2.4GHz band is where this matters the most, because the interference is more common there. The 5GHz and 6GHz bands usually have more channels available, but yes, they can also become congested.
In your router settings, set the Wi-Fi channel selection to manual and choose channels 1, 6, or 11 for the 2.4GHz band. For the 5GHz band, channels 36, 40, 44, or 48 are often good starting points. If you need to see which channels your neighbors are using and want to avoid them, you can use a Wi-Fi analyzer app and run a quick scan. Understanding radio frequency interference can make a huge difference in your wireless performance. The 2.4GHz band is particularly crowded because it shares spectrum with Bluetooth devices, microwaves, and cordless phones. By selecting a non-overlapping channel, you reduce co-channel interference and improve signal quality. For the 5GHz band, which offers more channels and less interference, it’s still worth checking for congestion, especially in apartment buildings.
Set up a DNS
Ditch your ISP’s DNS
DNS is what’s responsible for converting those website names you type in your browser into IP addresses that your device can understand. By default, your router uses the DNS provider provided by your ISP. While there’s nothing wrong with that, ISP-provided DNS servers aren’t always the fastest or the most reliable option. Switching to a third-party DNS service, like Cloudflare or Google DNS, can make website load a little faster by reducing the time it takes to convert website names into IP addresses. Beyond speeds, these DNS servers often offer better protection against malicious domains and stronger privacy than ISP-run alternatives.
Another major benefit of changing the DNS at the router level is that it applies to every device that connects to the network. That can save you the hassle of changing the DNS settings on your phone, tablet, PC, and TV manually. Historically, ISPs have used DNS as a way to collect user data or redirect users to their own advertising pages. By switching to a reputable third-party DNS like Cloudflare (1.1.1.1) or Google (8.8.8.8), you not only improve speed but also enhance your privacy. Many of these services also support DNS-over-HTTPS or DNS-over-TLS, adding an extra layer of encryption to your queries. This prevents your ISP from seeing which websites you visit, and it also reduces the risk of DNS spoofing attacks.
Some routers allow you to configure multiple DNS servers as fallbacks. For maximum reliability, you can set both primary and secondary DNS addresses from different providers. For example, use Cloudflare as primary and Google as secondary. This ensures that if one service goes down, your network still works seamlessly. The configuration process usually takes less than a minute and is one of the most impactful changes you can make.
Change the router password
Secure your router before someone else does
Most people never bother to change their router’s default login credentials. That also means anyone who’s connected to the network can easily access the router's settings page using the default credentials printed on the router or listed on the manufacturer’s support website. And once they’re in, they can change the Wi-Fi password, disable security settings, prioritize their own devices, and even lock specific users out. To be fair, some new routers now ask you to change the default credentials during the setup process. But not all of them do. In any case, it’s always best to change the default login password to something strong.
The default credentials for routers are often well-known, such as 'admin/admin' or 'admin/password'. Attackers can easily find these online. Changing the router admin password is your first line of defense against unauthorized access to your network configuration. When creating a new password, use a mix of uppercase and lowercase letters, numbers, and special characters. Avoid common words or easily guessable information. Some routers also allow you to change the username, which adds an extra layer of security. If your router supports two-factor authentication, enable that as well. Even a simple password change can thwart most casual attacks.
Update to the latest firmware
New router, old software? Fix that first
A new router might not always be running the latest firmware. If it was sitting in a warehouse or on a store shelf for months before you bought it, there’s a good chance it’s running an old version. Much like software updates on a phone or PC, router firmware updates can patch security vulnerabilities, improve stability, fix bugs, and sometimes even improve performance. On newer router models, checking for updates and installing them is as easy as clicking a button. But on an older one, you may need to download the update file and install it manually. Either way, it’s not something you should skip.
Firmware updates are often released by manufacturers to address newly discovered security flaws. Without these updates, your router could be vulnerable to exploits that allow attackers to hijack your network or steal your data. For example, in 2020, a critical vulnerability in certain Netgear routers allowed remote attackers to execute commands without authentication. The fix was only available via a firmware update. By regularly checking for updates, you ensure that your router has the latest security patches. Many modern routers have automatic update options, but not all enable them by default. Make sure to enable automatic updates if available, or set a monthly reminder to check manually. Updating firmware is one of the most important steps you can take to protect your home network.
Changing the default router settings isn't the most exciting thing to do, but it's just as important as choosing the right location for the router. And you only need to do it once, so there's no good reason to skip it.
