If your Adroid cannot detect a WiFi network, first of all you have to find out which is causing the problem: the device that shares the wireless network (modem/ router) or your Android phone/ tablet. Show Finding the Source of TroubleFirst of all, you have to check if Android can see other WiFi networks. Try to share Internet connection from a laptop or go to a public place with a free WiFi hotspot. If there are no problems with detecting other access points, the issue is definitely in the network which is not found by Android. However, if the device is not able to detect any access points while other phones show they are available, you have to look for defects in the system and hardware. Android does not Detect any Wi-Fi NetworksIf the device cannot find any wireless access points although it used to see them, make sure that there are no errors in the system and that the module operates properly.
There is a resetting network parameters option in the settings of the most recent Android versions. You can use it to rectify some system failures without resetting the device or deleting any data from the memory.
If the problems with Wi-Fi connection have occurred after updating or reflashing, you have to roll back to the latest steadily operating Android version. Use official or reliable custom assemblies for flashing, then system failures will arise much less frequently. The worse thing that can happen to your phone or tablet is a hardware failure. If you suspect that the wireless connection module might be out of order, take it to a service center to have it troubleshooted and the faulty component replaced. TroubleshootingBefore commencing any serious equipment diagnostics, take some simple steps:
That is all you can do at your Android device. If you still cannot see the network after taking all the above actions, start checking and setting the signal source. Setting the RouterIf you have access to the router, check its settings. The following may help:

The described methods are also viable for other devices that share Wi-Fi. If you are using some third-party software to create a wireless connection from your laptop or phone, make sure that the mobile access point is adjusted correctly. Try to connect to it from another phone and if you cannot establish the connection, create the access point once again. |
