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 are not always ideal. If you have spent hours researching which router to buy, you should definitely spend a few more minutes optimizing it. The following six adjustments are essential for unlocking the full potential of your new router, ensuring faster speeds, more stable connections, and stronger security.

Turn off WPS

The outdated feature isn't worth the risk

You may have noticed a WPS (Wi-Fi Protected Setup) button on your router and never known what it is for. Its main purpose is to let you connect devices to the network without entering that complex Wi-Fi password you have set. Yes, WPS sounds useful, which is also why it comes pre-enabled on most routers. But there is 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 is better to turn it off entirely. The process is usually simple: log into your router's web interface, navigate to the wireless settings, and disable WPS. Some routers even give you the option to disable just the PIN method while keeping the push-button method. Disabling WPS entirely is the safest choice.

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. To enable QoS, look for the QoS settings in your router's advanced configuration. You can often assign bandwidth limits or priority levels by device MAC address or by traffic type. This is particularly useful in households with multiple users who engage in bandwidth-intensive activities simultaneously.

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. This simple step can dramatically improve your wireless performance, especially in apartments or densely populated neighborhoods.

Set up a DNS

Ditch your ISP's DNS

DNS is what is 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 is nothing wrong with that, ISP-provided DNS servers are not 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. To change your DNS, log into your router, find the DNS settings (usually under WAN or Internet settings), and enter the preferred and alternate DNS addresses of your chosen provider. Cloudflare's primary DNS is 1.1.1.1, and Google's is 8.8.8.8.

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 is 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 are 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 is always best to change the default login password to something strong. Look for the administration or management section in your router settings. Create a complex password that includes a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using common words or phrases. This simple step adds a crucial layer of security to your network.

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 is a good chance it is 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 is not something you should skip. To update your router's firmware, log into the administration interface, look for a firmware update or system update section, and check for new versions. If available, follow the on-screen instructions to download and install the update. Make sure not to interrupt the power during the update process, as that could brick the router. Keeping your router's firmware up to date is one of the most effective ways to ensure long-term security and performance.
