If you’re having trouble logging in to your ISP account or getting online, it may be because your authentication failure is preventing you from accessing the internet. Here are a few tips to help fix the issue:

  1. Check your ISP’s website for troubleshooting instructions. If you can’t find them, ask your ISP how to fix authentication failure on their own site.
  2. Reset your router’s password if it hasn’t been done in a while. Resetting the password can help fix any issues that may have arisen from the authentication failure.
  3. Try using another browser or device instead of your ISP’s login page. This could include using a different computer or device, checking online resources for solutions, or even trying out different login methods until you find one that works for you.
