 1. Using the Router’s Configuration Web Page:
As mentioned In This Post , you can connect to router’s configuration page by typing the router’s default IP address in an explorer (such as Google Chrome, Firefox, Internet explorer …). “If you don’t know the default router’s IP address , take a look to the router’s label “
When you enter the router’s default IP address, a page similar to the following page will be appears and asking you to enter the router’s user name and password for login to the configuration’s page:
If you have not changed the default configurations, you must use the default username and password to login, which is usually written in the router’s label:
Usually,the default username and password is “admin“
Now that you can get access to the device settings, just navigate to the “Credential Settings “ or ” Maintenance –>Administration” and change the Router’s Login Password. (Note that the default username in most routers is “Admin” and there is usually no need to change that).
 2. Using the Router’s Management Mobile Application:
In this method, the user just needs to install the router’s management application introduced by the manufacturer on his mobile phone or tablet. Then connect to the WiFi router. (All routers have a default network name whose specifications are written on the label on the back of the router.
If the router has not been configured, connect to it using this default information). After connecting to the WiFi network, run the router’s management application and proceed according to the steps mentioned in the router’s manual.
       For example, the method of configuring an Asus router ( for the first time ) using the official program of this router is as follows :
First download official App from Google Play or App Store. and follow the steps below :
1. Turn on the phone’s WiFi connection and connect to Router’s default network name (SSID). the default network name starts with “ASUS_XX“.

2. Tap on the ASUS Router app.
3. Tap “Setup”.
4. Tap “ASUS Router”.
5. Choose “Allow” to start the setup.
