Hi@mukhtarco791,

To change the Wi-Fi settings on your TP-Link access point like wireless name or password, follow these steps:
1. Connect your computer, phone, or tablet to the access point's wireless network, and visit http://tplinkap.net/. 
2. For newer models, the wireless settings can be altered under Wireless > Wireless Settings.  
3. For older models, go to Wireless > Wireless Settings to modify its Wi-Fi name(Wireless Network Name). 
The wireless password can be customized under Wireless > Wireless Security > WPA/WPA2 - Personal(Recommended). 
You may also go through the Quick Setup to change them both at the same time. 
4. For the models: AP500, AP300 and AP200, go to Advanced > Wireless > Basic Settings. Click 2.4GHz or 5GHz to change their Wi-Fi name & password separately.

When you first log in to the web interface of the access point, you need to create a login/Local password to manager the device. If you forget the login/admin password you created before, you need to reset the access point back to default settings.
How to reset: Press and hold the reset button until the Power LED blinks.
If you want to change the admin password, please visit http://tplinkap.net, log in to the access point with the old admin password, and go to System > Administration > Change Password.
