Error 797: A Connection to the Remote Access Server was not Made because the Modem was not Found

Yesterday, I received an error message while trying to connect to the internet on my laptop: "Error 797: A connection to the Remote Access Server was not made because the modem was not found."

Let me share the screenshot of the error message here.

A regular reader of CoreNetworkZ Tech Solutions, Rajeev Jose, asked when I saw this error.

It occurred when I connected a USB modem from one of my Internet Service Providers and mistakenly clicked the connection shortcut for another provider.

In this instance, I had plugged in the Photon modem but clicked the Netconnect connection wizard.

However, after publishing this tutorial, I received multiple responses from the readers of CoreNetworkZ Tech Solutions about the same error message for different reasons.

The main reason behind the error code: “Error 797: A Connection to the Remote Access Server was not made because the modem was not found” is that the computer failed to detect the modem. So, it could not establish a connection to the Internet Service Provider (ISP).

According to Ashish Mudgal, a senior Network Engineer at CoreNetworkZ Tech Solutions, this error occurs if the modem has not been installed properly on your system.

Another common cause involves port-related issues, such as a non-responsive or faulty port. Anupama Thomas, a Software Engineer from Bengaluru, mentioned it in our support forum.

She said, "My ISP modem had a port issue. When I connected the modem to my Dell Windows 11 laptop, it showed the error 797: modem not found."

Connection problems (e.g., loose connections, damaged Ethernet cables, etc.) can result in error 797: modem not found.

If your system is not detecting the modem, follow these steps:

1. Use the Correct Connection Shortcut

   Let me share the first step from my experience. I clicked the wrong connection shortcut and received error 797. So, ensure you have clicked the connection shortcut that matches the connected modem.

2. Power Cycle the Modem

   It is the most effective solution to fix error 797. Power cycling the modem and computer network solved this problem on my clients' computers. Let me explain how to do it.

   1. For USB modems: Unplug the modem from your computer, wait a few seconds, and then replug it. Melvin Joseph, a client of CoreNetworkZ Tech Solutions, once asked exactly how long he should wait until replugging the USB modem. I recommended 30 seconds.

   2. For non-USB modems: Turn off the device, wait about one minute, then turn it back on. Wait until the power indicator light becomes steady.

   Now, check whether the same alert still appears.

3. Disable and Re-enable the Network Adapter

   If the issue is related to the Network Interface Card (NIC), try disabling and then re-enabling the adapter. For detailed instructions, visit the link:

4. Update the Modem Driver

   Driver-related compatibility problems may trigger this error. While many internal modem models use generic drivers, some require a specific version.

   

   If your internal modem runs on an outdated driver, update it through Device Manager.
