Error 777 :The Connection Attempt failed due to Remote Computer Out of Order

For the last few weeks, I have been getting an error message "Error 777: The Connection attempt failed because the modem (or other connecting devices) on the remote computer is out of order" while connecting to the Internet. I use Huawei Access Manager to connect to the Internet because the modem provided by Tata Photon Plus is from Huawei. Mainly the issue occurs in the evening (that means the peak time) and the error message prompt me to either redial to connect to the Internet or cancel. Here I would like to share the major reasons of "Error 777: The Connection attempt failed" and its possible solutions. After a few attempts, I would be able to go online but in some worse cases, I waited hours to get rid of the error.

If you are not sure how this error message looks like, have a look at the screenshot provided below.



The possible reasons for "Error 777: The Connection attempt failed because the modem (or other connecting devices) on the remote computer is out of order" are:

1. Usage of the incorrect driver for your modem
   
   
2. The number dialed by your modem is blacklisted
   
   
3. Outdated modem driver

In addition to the above-mentioned reasons, I am getting this error message only in peak time. So I assume, the network users can also be a factor but I am not sure.

1. Configure Airtel Broadband Modem
2. Idea 4G APN Settings
3. Destination host unreachable

The major reason for "Error 777: The Connection attempt failed because the modem (or other connecting device) on the remote computer is out of order" is faulty modem driver. However, in my experience just restarting the computer itself fixed this issue. So here I would like to share a practical guide to fix this error message.

1. Unplug the modem and reconnect (If you are using a USB modem or external modem )
   
   
2. Restart your computer
   
   
3. Update the driver
   
   
4. Uninstall the current modem and reinstall it with the latest driver available.
