Problem 1: Unable to Connect to the Wireless Network

Follow the below-given steps to eliminate this issue:

Step 1: Make sure that you have plugged in the Wi-Fi router to a working outlet and the LED of your wireless (displayed on the front panel of the Wi-Fi) is on:

  • Solid blue light indicates the wireless radio is properly operating.
  • ‘Off’ indicates the wireless radio is not on.

Step 2: If the LED is off, press the wireless button, given at the back of the router, and hold it for about 5 seconds. Again, check the LED light.

If the LED is not solid blue, you need to unplug the wireless router and wait for about 10 seconds before plugging it back. After connecting to the power source, turn on your wireless. In case the LED is still not blue, you need to replace your device.

Step 3: Make sure the SSID is on the list of the available networks.

  • In case the SSID is not listed on your device, make sure you are within the range of your Wi-Fi router.
  • If you are within your wireless router's range, refresh the Wi-Fi manager.
  • If it is still not displaying SSID on the available wireless networks list, try to connect to a different device. If your another device is displaying the SSID, there is some issue with your device and therefore, needs to be replaced.
  • In case your another device is also not displaying the SSID in the available network, log in to the Router Genie to make sure the SSID is configured to broadcast.
  • In case the SSID is configured to broadcast, check whether you have connected other devices to the network or not. If other units are connected to your Wi-Fi network, there is some issue with your device.
  • In case no devices are connected to the Wi-Fi network, power-cycle your Netgear router and Gateway modem. Refresh the Wi-Fi manager as well. 
  • If the SSID is not broadcasting, you need to ‘factory reset’ your wireless router.

Note: Attempting a ‘factory reset’ will remove all the settings configured to your router, including AP mode. After this, change the SSID name, admin password, passphrase, and also, configure the AP mode and enable the SSID broadcasting.

  • Check whether the SSID is broadcasting or not. If not, you need to replace your device.

Step 4: Try to reconnect to SSID and don’t forget to fill in the security passphrase. Contact your router administrator if you are unaware of your security passphrase. If you are the admin, log in to your device to get the security passphrase.

Step 5: In case you are not able to connect, try to connect to a different device. If it is connecting, then you need to change your device.

Step 6: Open a web browser from your computer system or a wireless device, which is connected to your router.

Step 7: Check if other devices are also connected to the network. If they are connected, there is some issue with your device.

  • If other devices are also not connected to the Wi-Fi network, power-cycle your Netgear router and the Gateway modem. Also, refresh the Wi-Fi manager.
  • Once again try to connect to the network. If you are unable to do so, you need to ‘factory reset’ your Netgear wireless router.

Note: Attempting a ‘factory reset’ will remove all the settings configured to your router, including AP mode.

Step 8: After the factory reset, change the SSID name, admin password, passphrase as well as configure the AP mode and enable the SSID broadcasting. Check whether you are able to connect or not. If not, you need to replace your device.

Problem 2: Unable to Surf When Connected to the Wireless Networks

Assess whether you are having the issue with a single device or on all the devices.

When the issue is with a single device

Step 1: Make sure you are connected to the right wireless network and connected to the Internet.

Step 2: Refresh the Wi-Fi manager. If the issue still persists, you are having the problem with your device.

When the issue is with all the devices

Step 1: Connect to your Netgear router directly

If you are able to surf while connected to your Netgear router directly, refresh the Wi-Fi manager and try to surf wirelessly. In case you are not able to surf wirelessly, reset your router to the ‘factory default.’

Note: Attempting a ‘factory reset’ will remove all the settings configured to your router, including AP mode.

In case you are unable to surf while connected to the Netgear router directly, connect to Comcast Gateway. Unplug the Ethernet cable from your router and connect it directly to the computer. If you are still not able to surf while being directly connected to the Comcast Gateway, get in touch with Comcast Business Customer Support for further assistance.

If you are able to surf while being directly connected to the Comcast gateway, follow the below-given instructions:

  • Turn your Gateway modem off and unplug it.
  • Turn off your computer and the router.
  • Plug the Gateway modem back in and turn it on. Now, wait for about 2 minutes.
  • Then, turn your router on and wait for about 2 minutes.
  • Turn on your computer, smartphone or laptop.
  • Try to surf while being directly connected to the Netgear Wireless Gateway.

In case you are not able to surf while being directly connected, reset your router to factory default.

Note: Attempting a ‘factory reset’ will eliminate all the settings configured to your router, including AP mode.

If you can surf while being directly connected to your Netgear router, refresh the Wi-Fi manager and try to connect wirelessly. In case with all the connected devices, you are not able to surf wirelessly, call Comcast for additional assistance.

Problem 3: Not Able to Access the Network Drivers

If you are not able to access the network drivers, there are chances that your Netgear router is set to NAT over NAT. This allows users to gain Internet access but does not grant access to the internal network. To get the access to the internal network, they have to configure their router to the AP mode.

Step 1: Connect to the router directly.

Step 2: Open a web browser on your computer.

Step 3: In the address bar, either type: http://www.routerlogin.com or http://www.routerlogin.net

Step 4: Enter your credentials, i.e., the username and password.

Step 5: If you don't remember your password and have set up the password recovery previously, follow:

  • Select the 'Cancel' option when the sign-in window appears to begin the password recovery procedure.
  • Fill in the correct answer to the security questions. In case you are not able to answer your security answers, or you have not enabled the password recovery, you need to reset your router to the factory default settings.

Note: Attempting a ‘factory reset’ will remove all the settings configured to your router, including AP mode.

Step 6: Follow: Advanced > Advanced Setup > Wireless AP

Step 7: Select the checkbox, available next to 'Enable the Access point Mode' and choose the 'Apply' option.

By following the above-discussed, stepwise troubleshooting instructions, you will be able to resolve issues with your Comcast Business Private Wi-Fi. In case you need additional information or support, contact Comcast Business Support number [icustomerservice.net/comcast-customer-service] right away.
