Fixed: Getting Routerlogin.net Certificate Not Trusted Error

Many users encounter the "routerlogin.net's certificate is not trusted" error when accessing their router's admin page. This prevents you from logging into your router to manage settings and troubleshoot connection issues. Fortunately, you can take a few simple steps to fix this routerlogin.net certificate error.

What Causes the Routerlogin.net Certificate Error?

Routerlogin.net is the default web address to access the admin console on many router brands, including Netgear, Linksys, and Asus. When you attempt to navigate to routerlogin.net, your browser checks the website's security certificate to verify its authenticity. You will get an error if the certificate is invalid, expired, or not trusted.

Some common reasons for the invalid certificate error include:

• An expired certificate - Certificates have an expiration date set by the issuer. The error will appear if the router cert is past its expiry date.
• Self-signed certificate - Many routers use a generic, self-signed cert not issued by a trusted authority. Your browser sees this as untrustworthy.
• Certificate doesn't match address - A mismatch error will occur if the domain name on the cert doesn't match what you entered.
• Connection interception - Public Wi-Fi networks often intercept traffic, triggering specific errors when you visit any HTTPS site.

How to Fix the Routerlogin.net Certificate Error

Here are five tips to resolve the routerlogin.net certificate error depending on the cause:

1. Check the Date and Time Settings

An expired certificate error means your router's clock needs to be revised. This causes the valid cert to appear expired to your browser. To fix this:

• Log into your router and navigate to the Date and Time settings.
• Select your time zone and check the box to sync the time with an NTP server. This will retrieve the correct date/time over the Internet.
• Save your settings and restart the router. The certificate should now appear valid.

1. Remove any Security Software Temporarily.

Antivirus software and firewalls can sometimes intercept traffic and trigger certificate warnings. Try turning off any security programs on your computer, then reaccess routerlogin.net. If the error goes away, you can re-enable the software afterward.

1. Renew the Certificate

Some routers let you generate a new security certificate through the admin interface. Log into your router, go to the certificate settings, and renew or reissue the certificate. This will provide an updated, valid certificate for routerlogin.net.

1. Install a Signed Certificate

Install a signed certificate from a trusted Certificate Authority (CA) like Comodo or Digicert for a permanent fix. You can then access routerlogin.net without any certificate errors. Here's how:

• Purchase a signed SSL certificate for your routerlogin.net domain from a CA.
• Log into your router and navigate to the certificate settings.
• Upload the new signed certificate files.
• Restart the router to apply the certificate.

1. Bypass the Warning

If your connection is safe, you can bypass the invalid certificate warnings. In Chrome or Firefox, click "Advanced" and then "Proceed to routerlogin.net." In Safari, click "Show Details" and then visit the site. This temporary workaround lets you access the admin console until you resolve the certificate issue.

Preventing Future Routerlogin.net Certificate Problems

To avoid recurring certificate errors in the future, follow these tips:

• Set your router to sync time with an NTP server automatically.
• Renew or replace the default certificate annually before it expires.
• Use a static WAN IP address and register it with a DNS for a consistent routerlogin.net address.
• Only access routerlogin.net over private, password-protected Wi-Fi networks to avoid interception.

Router manufacturers could simplify things by providing a permanent signed certificate pre-installed on new routers. Until then, users should periodically check the admin console certificate to ensure it remains up-to-date and trusted by browsers. Taking proactive steps to maintain a valid router certificate will prevent frustrating login errors.
