Your router controls how every device in your home connects to the internet, but most default settings are built for convenience rather than security or performance. A few quick changes inside the router admin page can close obvious security gaps, reduce interference, and help your network run more smoothly.
Getting Started: How to Access Your Router Admin Page
Before you can improve router settings, you need to log into the router’s admin interface. Open a web browser and enter the router’s local IP address, which is usually something like 192.168.1.1 or 192.168.0.1. If those do not work, check the sticker on the router itself or search the exact model number with “admin login page.”
This login is not the same as your WiFi password. The WiFi password connects phones, laptops, and consoles to the network. The admin password controls the router itself. If the admin login still uses a default credential like admin or password, that should be changed immediately.
1. Change the Default Admin Password
Changing the router’s admin password is the most important first step. If the default login is still active, anyone who gains access to your network or a malicious program on one of your devices may be able to change DNS settings, open ports, or redirect traffic.
Log into the router, go to the Administration, Management, or Advanced section, and look for an option such as Set Password, Admin Password, or Router Login. Use a unique password that is different from your WiFi password.
Why this matters
Many users protect the wireless network but forget the router itself. That leaves the gateway open. Securing the admin login prevents unwanted changes to the settings that control your whole home network.
2. Disable UPnP to Close an Easy Security Hole
UPnP, or Universal Plug and Play, allows apps and devices to automatically open ports through your router’s firewall. It is convenient for games, peer-to-peer software, and some smart devices, but it also creates a risk because any approved program can request firewall changes without you manually reviewing them.
Think of your internet connection like a highway with thousands of lanes, and your router firewall as the toll booth controlling which traffic gets through. UPnP removes some of that manual control. Security professionals generally prefer it disabled unless there is a specific reason to keep it on.

What to do instead
Go to the router’s Advanced, LAN, or NAT settings and disable UPnP. If a game, console, or application stops working properly afterward, manually forward only the ports that device or app actually needs instead of leaving automatic access wide open.
3. Switch to Better DNS Servers
Your router usually uses your internet provider’s default DNS servers, but you are not locked into them. DNS is the system that translates domain names like youtube.com into IP addresses, and changing it can improve lookup speed, reliability, and sometimes privacy.
In your router’s Internet Settings, WAN, or Network Settings page, look for Primary DNS and Secondary DNS. Common alternatives include Google DNS at 8.8.8.8 and 8.8.4.4, or Cloudflare DNS at 1.1.1.1 and 1.0.0.1.
Speed and privacy benefits
A better DNS provider can make the network feel more responsive, especially when websites or services are slow to resolve. Some DNS services also offer filtering options for malware or family-safe browsing, which adds another layer of control beyond raw speed.
4. Optimise WiFi Channel Width for Your Environment
Wider WiFi channels can increase throughput, but they are not always the best choice. In crowded environments such as flats or apartment blocks, overly wide channels often create more interference and instability than real-world speed gains.
The 2.4GHz band is especially crowded because it only has a small number of non-overlapping 20MHz channels. On that band, 20MHz is usually the safest and most stable option. For 5GHz, 40MHz or 80MHz can work well, depending on how many nearby networks are competing for space.
Why Your Wi-Fi Is Slow (Even With a Fast Plan)
Practical channel width advice
Open Wireless Settings on your router, choose the band you want to edit, and set the channel width manually. For 2.4GHz, use 20MHz in most homes. For 5GHz, try 40MHz or 80MHz and test stability. Very wide 160MHz channels can look appealing on paper, but they are often a bad fit in busy areas and may run into DFS channel issues.
DFS, or Dynamic Frequency Selection, means the router must move off certain channels if it detects radar activity. In practice, this can lead to sudden drops, instability, or the network temporarily changing behavior when using very wide channel bonding.
5. Disable WPS
WPS, or Wi-Fi Protected Setup, is the feature that lets devices connect using a button press or PIN instead of entering the WiFi password. It was designed for convenience, but it is widely considered outdated and insecure, especially on routers that still expose PIN-based pairing.
In most homes, WPS is unnecessary because modern devices connect normally with a standard wireless password. Look in the Wireless or Advanced Wireless section and disable any WPS toggle, PIN pairing option, or Enable Router’s PIN setting.
Why WPS is no longer worth keeping
If you already know your WiFi password, WPS adds very little value and increases attack surface. Removing legacy convenience features like WPS is one of the easiest ways to tighten router security without affecting daily use.
Bonus Setting: Disable Remote Administration
Remote administration allows router management from outside your home network over the internet. For most users, this is an unnecessary risk. Unless you specifically need it for a managed setup, it should be turned off.
Check the router’s Administration, Remote Access, or Management section and make sure remote management is disabled. If attackers can reach the admin page from the internet, the router becomes a much higher-value target.
A Simple Router Optimisation Checklist
Once you are inside the admin interface, focus on the settings that make the biggest difference first. Do not try to change everything at once. Apply the essentials, test the network, and only then move on to advanced tuning.
- Change the default router admin password
- Disable UPnP unless you specifically need it
- Set a custom DNS provider such as Cloudflare or Google
- Use 20MHz on 2.4GHz to reduce interference
- Test 40MHz or 80MHz on 5GHz based on nearby congestion
- Disable WPS and router PIN pairing
- Turn off remote administration from the internet
Final Thoughts
Router settings have a direct effect on both home network security and WiFi performance. Leaving everything on default usually means living with avoidable risks and less consistent speeds. A few targeted changes can make the network harder to abuse, easier to manage, and better suited to your environment.
Start with the admin password, UPnP, WPS, and remote management. Then tune DNS and channel width based on how your home actually uses the network. That gives you a safer setup without making the router harder to live with.

FAQ
No. The WiFi password is used by devices joining your wireless network. The admin password is used to log into the router settings page and manage the network itself.
UPnP is convenient, but it can open ports automatically without much user oversight. That makes it a security risk for many home networks. Disabling it and using manual port forwarding only when needed is usually safer.
There is no single best DNS for every location, but Cloudflare and Google DNS are common choices because they are widely available and often faster than ISP defaults. The best option depends on your region and provider routing.
On 2.4GHz, 20MHz is usually the better choice because it reduces overlap and interference. On 5GHz, 40MHz or 80MHz can improve speed if your area is not too congested.
In most cases, you will need to factory reset the router and set it up again from scratch. That is why it is worth storing the new admin password in a password manager.
