If you’re wondering why is the BGW320 Ethernet not working? Stay with us here in this guide!
If none of the Ethernet ports on your BGW320 gateway seem to be working, there could be an issue with the LAN configuration or the firmware network protocols.
This guide will help you uncover the exact cause of the inactive LAN installment and help you learn how to resolve this.
Whenever the Ethernet port on your BGW320 gateways is not working, you must check if the Ethernet/patch cable is functional and restart the service connection.
Why Are the BGW320-505 Ethernet Ports Not Working?
The BGW320-505 Ethernet ports may suddenly stop working if:
How to Run AT&T Ethernet Test?
There’s a tool designed by AT&T that allows users to inspect all service aspects of the gateway, including the BGW320.
After running the checker, all issues with the LAN ports on the gateway will be reflected underneath the “Ethernet” status on the results table.
Here’s how to access AT&T’s network test:
- Connect a device to your AT&T network over Wi-Fi.
- Next, paste down the default gateway in a browser.
- Sign in to the online web GUI of the BGW gateway.
- Access the “Network” tab and press on “Run Test”.
- Finally, check the “Ethernet” line on the results table.
If all test results came out positive, except for the “Ethernet” line, then there’s an issue with your LAN configuration.
Before proceeding any further, ensure you’ve tested the Ethernet cable on all available ports, except for the “ONT” port, meant for service connection.
BGW320 Ethernet Not Working – Effective Solutions
Tip: Follow all subsequent solutions in consecutive order!
1. Reseat the Ethernet Cable
There’s a chance that the Ethernet connection is loose or unsecured, preventing the receiving device from recognizing the LAN connection.
Hence, the first and best-working solution would be to reseat the Ethernet cable and refresh the LAN connectivity of the receiving device.
Follow these steps to reseat the Ethernet cable in easy steps properly:
- Disconnect the Ethernet cable from the back of the BGW gateway.
- Unplug the other end of the cable from the receiving device port.
- Wait for 30 seconds while the Ethernet service cable is unplugged.
- Next, reattach the cable to one of the yellow ports on the gateway.
- Reconnect the other end of the cable to the receiving device’s port.
How to Recognize the BGW320 Service Port?
The service port on the BGW320 is labeled with an “ONT” sticker to help all users identify the service connection quickly.
So, if you’re attempting to connect a third-party device that isn’t an ONT to the service port, the Ethernet connection’s data packets will not be transferred entirely.
Note: Always connect third-party devices to your BGW via one of the yellow Ethernet ports!
2. Power Reset the AT&T BGW320
There’s a chance that the LAN configuration has been temporarily put out of order due to an issue with the power supply.
To address fluctuations in the A/C equipment, it is strongly advised to power circulate the BGW gateway by disconnecting the supplying power cord from the A/C.
Follow these steps to perform a power reset on the AT&T BGW320 gateway:
- Unplug the power cord of the gateway from power.
- Unplug the other end of the cable from the gateway.
- Wait for 60 seconds while the BGW is disconnected.
- Secure the cord of the network device on both ends.
- Wait until the AT&T gateway reboots, and then test.
If the problem continues, keep reading!
3. Reinstall the ONT Service Cable
A loose or fluctuating service connection with the network ONT (fiber switch) can impact the functionality of the LAN installment on your gateway.
If the fiber connectivity protocols cannot be decoded correctly by the BGW320, none of the Ethernet ports will function for other devices.
Here’s how to reinstall the ONT service cable on your BGW320 gateway:
- Identify the service cable plugged into the “ONT” port on the BGW.
- Disconnect the service Ethernet cable from the back of the device.
- Next, unplug the other end of the AT&T service cable on the wall.
- Wait for 60 seconds while the BGW320 is not receiving service.
- Reinstall the service cable into the AT&T service box and gateway.
Potential issues with the service connection of the BGW320 will heavily impact the protocol transferring and decoding between devices in your local network.
Hence, verify that the service cable is in proper condition and reduce the number of devices plugged into the same switch.
Alert: Contact AT&T customer support for defective service equipment, box, or cable!
4. Inspect the Receiving Ethernet Device
It is possible that the third-party device you’re attempting to connect isn’t compatible with the local area network of the BGW320 or simply hasn’t been set up.
It is necessary to determine whether your device requires manual network setup or decoding protocols are automatic.
Most devices must undergo a “Wired Setup” procedure, typically found within the connectivity settings of the unit, to recognize a connected Ethernet cable.
How to Setup Device for Wired Connection?
You must manually set up the wired connection with most third-party devices that can be added to a LAN network, such as TVs, computers, laptops, and smart speakers.
- So, open the settings tab of the device and navigate to Settings > Network > “Wired Connection.”
Note: You may be prompted to input network information during wired connection setup!
5. Replace the Ethernet/Patch Cable!
It is possible that the Ethernet cable used for connecting third-party devices is simply defective or isn’t transferring the data packets reliably.
To determine if a defective cable causes the issue with the BGW320’s Ethernet ports, installing a new (working) Ethernet cable is recommended.
We advise using a CAT5e or CAT6 Ethernet for the best compatibility with the local area network connectivity requirements of the BGW320.
If possible, round up some old cables you have lying around at home and test each of the wires with the yellow ports on the BGW320.
Alert: You can connect the Ethernet/patch cable to a service wall outlet for testing purposes!
How to Test a Patch Cable with an Ethernet Tester?
With the assistance of a patch cable tester, you can check all 8 transmission lines of your CAT or RJ Ethernet cable.
Connect one of the Ethernet cable’s ends to the “TX+” port on the tester, plug the other end into the “PR 2/3/4” port, and check whether the results on the tester match.
Note: Each successfully connected transmission line will ding on a sound-enabled tester!
6. Request a Firmware Downgrade!
The abnormal behavior of the LAN ports on your BGW320 device is most often associated with discrepancies with the latest firmware.
As long as the BGW gateway is connected to service and power, it updates automatically whenever newer firmware is detected.
Since AT&T does not allow users to self-downgrade the firmware version of service gateways, you must request it via customer support.
If the BGW320’s LAN configuration has recently stopped working, the newest firmware might have stopped detecting the Ethernet configuration.
How to Request BGW320 Firmware Downgrade?
To talk with a customer support representative, dial AT&T at 800.288.2020 and request to talk with a technician from the user support.
Thus, provide them with the necessary information for identifying your setup via the client credentials and talk them through the details of the issue.
You may have to provide the current firmware version of the BGW320, found on the web GUI configuration of the gateway, to receive licensed troubleshooting.
Finally, request a downgrade of the firmware version if the gateway system has been updated recently.
Hence, whenever the BGW320 Ethernet is not working, first check if the connection of the Ethernet is secure and test the cable on all available ports.
If the issue persists, factory reset the BGW320 gateway and request a firmware downgrade from AT&T support!
