Unable to Connect to Internet

I called Roku support and after an agonizing 49 minutes for the agents and myself, the solution finally was found.  The agents recognized the error code (password) but could have done a better job with how to present the solution. This will sound like denial but if it can help someone else, I'm willing to share.  The password was still correctly logged into the Roku TV, it had not changed. The solution to change the password to the wifi and then enter the new password into the Roku TV was the solution. However, it was simply a weird work around for the TV to accept the password. The rest of the devices in the home, which had the same old password were working correctly. Some update to the Roku TV or to the Internet Provider software created a disconnect to the old password for just the Roku TV. Oddest thing I ever saw and I've been in IT customer support for over 20 years. I was initially unwilling to accept the solution because the agents assumed the password was entered incorrectly. Repeatedly entering it in over and over was painfully humbling as I knew all other devices were working with the wifi and the password was working great for the tv for 4 months. Letting the customer know that the password itself is the problem and has to be updated rather than blaming the customer for entering the wrong password would have helped the solution go a lot faster.
