The website tplinkwifi.net is the management address of the TP-Link router. If you can not open tplinkwifi.net, there are several reasons.
1. Check if your computer or mobile device have been connected to the router.
2. Set your computer to dynamic IP. If you can not get dynamic IP, you try to set your ip as 192.168.1.2.
3. CMD: ping 192.168.1.1 or ping 192.168.0.1, check the network.
4. Your TP-Link wireless router’s light is not green. If the light is red, there is a problem connecting to router.
5. Have you entered correctly? Don’t enter tplinkwifi.com or tp-linkwifi.net, they are wrong.
