Guidelines to Purchasing and Updating Your Home Router: Scambusters #1,244
Your router may be one of the most overlooked devices in your home. It connects your phones, computers, cameras, and other devices to the internet, but if it is not properly secured, it can also create a security risk.
Knowing what to look for when buying a router and keeping it updated can help protect your home network and the devices connected to it.
Router Safety: Is Your Home Network at Risk?
Your router can easily become a target for cybercriminals. Keeping your router safe depends on where it’s made, how you set it up, and how often you update it. Common risks include outdated software, default passwords, and routers from untrusted manufacturers.
Many people plug in their routers, connect to Wi-Fi, and then forget about them. This is a problem because routers connect every device in your home, yet they are often the least secure devices you own.
This article explains what a router does, why its origin is important, and what warning signs indicate that your network might be at risk.
What is a Router?
A router connects your home network to the internet. It directs data between your devices, like phones, laptops, smart TVs, and security cameras. You can think of it as a traffic controller: Every time you load a webpage, stream a video, or sync a smart device, your request goes through the router first.
Since routers handle a lot of data, they also serve as a gateway. If someone hacks a router, they can see, redirect, or intercept everything that passes through it.
Are Routers Used Only at Home?
Routers are used in many places, including homes, offices, schools, hospitals, and public spaces like coffee shops and airports. Business routers often have better security features and more oversight from IT staff. In contrast, home routers usually keep their factory settings and are rarely updated.
Public routers can be risky. Open Wi-Fi networks in cafes or airports are often unsecured, making it easier for someone on the same network to intercept unencrypted data.
Where Are Routers Manufactured? And Does It Matter?
Routers are made by companies from many countries, including the United States, China, Taiwan, and South Korea. Many well-known brands are manufactured in these countries. Most components, no matter the brand, come from global supply chains that involve multiple countries.
The country where a router is made is less important than how the company secures its products, communicates with users, and provides updates. Some routers, especially those from manufacturers connected to foreign governments, have raised concerns. People worry about possible backdoors or laws that require them to share data.
Choose a router from a company known for quickly fixing security issues if ongoing support is more important to you than price. Only pick a budget option if you’re willing to keep an eye on firmware updates yourself, as cheaper or less-known brands may stop providing support after a year or two.
What Guidelines Should Be Followed When Buying a Router?
Before purchasing a router, check for the following:
- Regular firmware updates – Check the manufacturer’s update history. If a router hasn’t received a security patch in over a year, it is a warning sign.
- WPA3 encryption support – The current standard for securing Wi-Fi is called WPA3. Older routers may only support WPA2, which is not as secure.
- Built-in firewall – Most modern routers have a firewall but make sure it is turned on by default.
- Reputable brand with public vulnerability disclosures – Companies that share their security problems and fix them are usually more trustworthy than those that do not publicly share their security issues.
- Support timeline – Find out how long the manufacturer will provide updates for this model.
How Does a Router Protect Me?
A properly configured router protects your network in several ways:
- Firewall protection – Stops any unauthorized connections from the internet.
- Network Address Translation (NAT) – It hides the individual IP addresses of devices on your network. This makes it harder for someone to target them directly.
- Encryption – It keeps data safe as it moves between your devices and the router by using protocols like WPA3.
- Guest network isolation – Keeps guest devices on a separate network from your main one. This reduces the risk if a guest device gets hacked.
These protections only work if you update and set up your router correctly. If your router has old firmware, it will not provide much protection, no matter how good its original features are.
Red Flags of an Unsafe Router
Watch for these warning signs:
- Default username and password still in use – Most router models are listed online, making them easy to access.
- No recent firmware updates – If the manufacturer has not provided a patch in over a year, security issues may remain unresolved.
- Unusual network activity – Slow performance, unknown devices on your network, or changes to your settings that you didn’t make.
- Remote management enabled without your knowledge – This lets you access your router’s settings from outside your home network.
- No WPA3 or WPA2 encryption option – Older encryption methods like WEP can be easily broken.
Can My Personal Information Be Taken?
A compromised router can expose your browsing history, login details, and data from smart devices connected to it. If attackers gain access to your router, they can redirect your internet traffic to fake websites that steal your passwords or financial information. This tactic is called DNS hijacking. They can also directly monitor any unencrypted traffic.
Smart home devices, like cameras, thermostats, and baby monitors, are at a higher risk when connected to a weak router. These devices often have less security than computers or phones.
How Can I Protect Myself From Any Potential Harm?
Take these steps to reduce your risk:
- Change the default login credentials immediately after setup.
- Update firmware regularly or enable automatic updates if available.
- Enable WPA3 encryption (or WPA2 if WPA3 isn’t supported).
- Disable remote management unless you specifically need it.
- Set up a guest network for visitors and smart home devices.
- Check connected devices periodically to confirm you recognize everything on your network.
- Replace routers older than 5 years, since older hardware often stops receiving security updates entirely.
The Bottom Line
A router is easy to overlook once it’s plugged in, but it is essential for internet access in your home. To keep your personal information secure, choose a trusted brand, keep the firmware updated, and look out for warning signs like default passwords or unusual network activity.
Understanding how a router works and its importance can be intimidating. There are many acronyms and details that make it hard to grasp.
This week, take ten minutes to log into your router’s settings. Make sure the firmware is up to date and change any default passwords that are still in place. This simple step can help protect you from common security risks.
Remember, Stay Alert and Stay Informed!
