Back in 2016, 2Wire was acquired by Arris for providing DSL routers to the users. In fact, they are still used in many households for personal and professional applications.
However, it becomes frustrating when you face problems with a 2Wire router and ultimately it stops working. Typically, you can fix most of the problems with a 2Wire router just by troubleshooting the specific case individually.
1. Power Light Issues
One of the commonly occurring issues with a 2Wire router is when the router turns into Power Cycling mode. As this situation occurs, the power light starts flashing green. Moreover, the internet connectivity is lost when power cycling starts. So, isn't that becomes inconvenient for you? Usually, this 2Wire router should end up the power cycle within a few minutes.
But if it does stop blinking, then try performing a soft reset function for your 2Wire router by unplugging the power cable from the backside of the router and the outlet that it's plugged into. Let it stay unplugged for about a minute and then plug it back into some other outlet. With this, you can analyze that your previous outlet isn't problematic. Further, wait for some time to check whether the 2Wire router's power light glows solid green or not. If so, then your router is working again.
Sometimes, your 2Wire router may flash an orange light which means that the router is upgrading its software. Let the software download and install the update in the next 10 to 15 minutes. If the power light glows red, then your 2Wire router or the power adapter has failed. Note that 2Wire power adapters aren't sold separately. Try replacing the 2Wire router until its blinking red.
2. DSL Failure
DSL failure is also one of the problems with a 2Wire router. When this occurs, there's a problem with the DSL connection, maybe because of a faulty cable or problems with your DSL company. As an issue occurs with the DSL connection, your 2Wire router's DSL light blinks green or red light. To troubleshoot this, you can check your phone lines and ensure that they have a dial tone.
If they have, then it means the problem is most likely with your cable or phone jack in which the modem and router are plugged into. So, try using another phone jack to check if the DSL light stops blinking. But it doesn't, then simply contact your DSL provider and get the signal repaired.
3. Authentication Failure
In some scenarios, the internet light on your 2Wire router turns into red or just not be lit up at all when there's an issue with your internet service provider's (ISP) servers. This can be fixed if you know about your connection as DHCP or PPPoE. If it's PPPoE, then you should know your username and password for your ISP account.
Visit the 2Wire router page on your computer at 192.168.1.254 and then log in to the router using the router username and password. Enter the username and password that were given to your ISP account in the PPPoE section. However, if you are still getting problems with a 2Wire router, then contact your ISP directly.
4. Enable UPnP on AT&T Router
Once you enable UPnP on your AT&T 2Wire router, then the ports are automatically forwarded for your devices. You don't need to manually set up port forwarding for online gaming devices like Xbox and PS4.
You can easily enable UPnP on your 2Wire router by logging in to your router settings at 192.168.1.254 and under the "Advanced" tab. Next, click on "Advanced Setup" and then select the "UPnP" option. You can check the box corresponding to "Turn UPnP" option and then click "Apply" to enable it.
Hope this guide fixes all the problems with a 2Wire router.
