Why Bother Writing This
Recently, I have noticed that a lot of users have problems connecting their Android-based smartphones and tablets to a wireless network. Seeing the “Authentication Problem Occurred” message or just the eternal “Authenticating” is never pleasurable. Well, I hate watching people struggling with their high-end mobile devices, and that’s why I’ve decided to write this article. So, let’s fix your connectivity problems.
Ensure that the cause of the connectivity problem is really the Android Phone
First things first. Before attempting any of the Android troubleshooting methods that are listed further below, you must make sure that the wireless network that you are trying to connect to is ok. Thus, you should try to connect to the wireless network through another device (preferably not another Android device). If the alternative device is also unable to connect to the wireless network, you should stop blaming and cursing your android smartphone and start troubleshooting the Wi-Fi hardware, software, and network settings. The first thing that you should try in this situation is to simply restart the wireless router (switch it off, wait ten seconds, and then switch it back on). Next, you should check the network settings, making sure that no ports, channels, or connectivity standards are disabled. Please also check the logs of your router for any recent attacks, such as synfloods. A successful network attack can limit the wireless functionality of your router. You should also try to solve the problem by disabling the MAC address authentication on the router and restart or reset the Comcast protocol. If the connectivity problem is still present, you should consider updating the firmware of the router and also making a hard reset (also known as factory defaults). Switching your wireless router from multi-protocol support to b/g or just n-standard could be another possible solution in your situation. Please also note that some old wireless routers do not support the wireless connectivity standards required by newer devices such as your android phone. Replace your wireless router if the above actions do not help.
Things to do when you are absolutely certain that the one to blame is the Android device
Reset the settings for the problematic wireless network
To reset the settings for the wireless network, you should navigate to the Wireless/Wi-Fi menu of your Android device, and then touch the name of the network until the settings menu appears. After that, you should select “Forget”, and then switch the Wireless of your device off. Now, you must switch the Wi-Fi back on, wait until the device finds the wireless network that you want to connect to, and then enter the shared network key. Congratulations if you have wireless internet now. If not, keep reading.
Disable All ANT and ANT+ apps
ANT is an extended android networking SDK that enables some really awesome connectivity and networking features. However, it can misfire in some situations, which inevitably leads to connectivity problems. Thus, you can try solving your Android Wi-Fi connectivity problems by disabling (Force Stop) all running ANT and ANT+ apps and processes. This is not a very graceful solution, but apparently it works.
Try using a Static IP
Fortunately, there are more troubleshooting solutions that you can try, such as the usage of a static IP. The static IP feature is available under the “Advance Options” sub-menu of the “Wi-Fi settings” menu. Please note that you will also have to enter additional info, such as subnet mask, gateway, netmask, and dns servers, in order to establish a connection using a static IP.
Airplane Mode, WPS (Push ‘n’ Connect), and Access Control
Another troubleshooting method that you should try is to switch the android device to an airplane mode, and then switch it back to normal mode. The success rate of this solution is relatively low, but yet you won’t lose anything by trying it. Alternatively, you can enable WPS, enter the required WPS pin, and connect your android device via WPS (Push ‘n’ Connect). Please, please, please also make sure that the Access control feature of your Android device is switched off.
