When you can power up the WiFi socket/switch normally but fail to control it, the first thing you should do is to check the blinking status of green indicator LED blinking status. Usually, there are two kinds of blinking statuses:
1. Green LED quickly blinks one time and repeats, which means the device has failed to connect to the router.
2. Green LED quickly blinks twice and repeats, which means the device has connected to the router but fail to connect to the server.
After judging the problem, you can troubleshoot the problems accordingly with below solutions.
8 Solutions to Failed to Connect to the Router
1. Wrong WiFi Name or PWD:
You may have entered wrong WiFi name and password in pairing process. Please make sure you have entered them exactly and select remember password.
2. Weak WiFi Signal
Your device may be too far away from the router, which causes a weak WiFi signal. Please try again with strong WiFi signal.
3. Phone Unable to Connect to WiFi
Your router or phone may come across some error, which causes a connection failure. Please make sure your phone can access to the WiFi router and works normally. If your phone has WiFi network in the Access Point but the device still fails to connect to the router, please refer to below solutions.
4. Too many devices connect to the AP
There might be too many devices connect to the AP which connects with the router, please turn off the devices or turn off the AP and try again
5. Too Many Connections to One Router
You may have too many devices connecting to one router. Please disconnect other devices and try again.
6. Router Error
Router error. Please restart your router and try again.
7. MAC Address Prohibited
For some security reason, your MAC address may be filtered and prohibited. Under such a condition, you should remove it from the prohibited address list.
8. MAC Address Conflict
Close all other connected devices to this router and try again.
9. DHCP tenancy term problem
Prohibit DHCP or extending DHCP tenancy term when DHCP is open.
10. Under the condition of disabled DHCP or open DHCP, you can extend the lease.
7 Solutions to Failed to Connect to Server
1. Unable to Visit Internet
If the whole outer network cannot be accessed, then use your phone or PC to visit Internet. If successful, try to connect your device again.
You may have downloaded too many files at the same time, which occupied most of the bandwidth, thus your device did not have enough bandwidth to connect to the server. If so, please stop downloading and try again.
3.More than one router with the same name
You may have more than one router with the same name, and your device may have connected to the non-networked one. In this case, you should reset your router name and choose the networked one to connect. Then try to connect your device again.
4.More than one DHCP server under one network
There may be errors existing between router topology. In this case, please check the connection way between routers, then try again.
If you have checked all above and found them no problems, maybe some terminal of the local area network you are locating has affected ARP virus. We suggest you to manually bind gateway and MAC address, then try again.
You may have opened firewall or some security software. In this case, please temporarily close them and try to connect the device again.
7.DNS Server Inaccessible
After making all above checks and finding them no problems, the possible problem should be DNS error. Please manually change DNS server address and try again.

Changing DNS for me did not help. My Pow device cannot connect to the Amazon IP 22.214.171.124.
