Can’t Log Into D-Link Router, What to Do?

The Basics

Caps Lock Check: It sounds silly, but double-check that Caps Lock isn’t on, as router passwords are case-sensitive.

Right Address: Verify you’re entering the router’s IP address correctly in the browser’s address bar. Find it using the “Default Gateway” method explained here. Before you do, to save time just try entering or in your browser’s address bar. That’s the default D-Link router IP Address.

Cable Check: Make sure that you are using an Ethernet cable connection between your computer and the router. Trying to do anything directly over WiFi will crash the connection when you click save to make the changes because the D-Link router will reboot when saving any new settings.

Forgotten Password?

Default Credentials: Check the router itself for a sticker listing the default username and password. It’s usually “admin” for both. If those don’t work try remembering whether you changed these yourself at a certain point back in the past.

Password Change: If you remember changing the password but can’t recall it, the hard reset option is your best way in (see below).

Still Locked Out? Deeper Troubleshooting

Browser Issues:

  • Clear your browser’s cache and cookies.
  • Use a different web browser to see if your current one just doesn’t want to make the connection to the router’s web interface.
  • Firewall Interference: Disable your firewall to rule out it blocking access to the router’s web interface. Enable it back afterwards if this didn’t fix it.

IP Conflict: In rare cases, another device on your network will be using the same IP address as your router. You can check your router’s DHCP settings to see the assigned range and check for conflicts. See how to change the D-Link Router IP address here.

The Nuclear Option: Hard Reset

Warning: This erases ALL custom settings on your router. Do this only as a last resort.

Locate the Reset Button on the D-Link WiFi Router: It’s a tiny, recessed button on the back of the router labeled “Reset.”

Press and Hold: Use a paperclip or sharp object and press and hold the reset button for about 30 seconds. You will see the router’s lights flash in a specific pattern.

Wait: Give the router a minute or two to fully reboot.

Default Login: Now, the default username and password (that we explained earlier) will work.

If all of this still didn’t work, you’re likely dealing with more complex issues.

Scenario 1: Browser Hijacking

Symptoms: When you type your router’s IP, you’re redirected to a strange website, search engine or a page full of ads.

Cause: Malware on your computer might be intercepting your traffic and redirecting you. But in this scenario you have bigger issues than connecting to your D-Link router.


Run Antivirus/Anti-Malware: Perform a thorough scan with your security software. Delete or quarantine all the infections it finds. Malwarebytes coupled with Windows Defender works pretty well.

Browser Reset: Sometimes malware embeds itself into the browser. Reset your browser to its default settings or uninstall it and reinstall it again.

Alternative Network Scan: Scan your computer from a different device or a bootable antivirus disk for a deeper cleaning.

Scenario 2: Accidental Router Settings Change

Symptoms: The default login works, but your custom settings are gone or the router acts like it’s fresh out of the box.


  • Someone else on your network performed a reset without telling you.
  • Power surges or glitches caused the corruption of some of the D-Link router’s settings.
  • Failing firmware on an older D-Link WiFi router will lead to spontaneous settings wipes.


Backup and Restore: If you had a recent backup configuration file saved, you will be able to restore it through your router’s settings interface.

Starting From Scratch: Unfortunately, you will have to reconfigure your router settings manually.

Firmware Update: You can download the firmware for the D-Link router you own and update it either in the browser interface after you factory reset it or by downloading it from the website and uploading it yourself.

Scenario 3: Advanced Network Configuration Issues

Symptoms: You’re reasonably sure of the IP and login, but they only seem to work intermittently.

Possible Causes:

  • Custom network configurations involving VLANs or subnets that are misbehaving.
  • Static IP settings on your computer that are wrong for the network.
  • More obscure things like corrupt routing tables on your PC.


Review Networks Settings: Double-check your computer’s network settings. If you use static IP, make sure it’s in the right range. Temporarily switch to DHCP (automatic) to test.

Windows Network Reset: (Windows 10/11): Settings –> Network & Internet –> Advanced network settings –> Network reset. (This resets various Windows network components.)

Router Logs: Your router’s logs will help you see what went wrong with the connection attempts.

Document Your Settings

To prevent frustration down the road, take screenshots or make a note of your key router settings (Wi-Fi names, passwords, security, etc.). This helps a lot if you ever need to reset or reconfigure the D-Link WiFi Router.
