Troubleshooting

Unstable connection on the TP-Link router
There are multiple factors that cause your internet connection to randomly disconnect. Please read possible solutions below which may fix an internet unstable.

Symptoms:
Both the wired connection and wireless connection are unstable
If this issue occurs with a wireless connection, please refer to Troubleshooting: Unstable wireless connection on TP-Link router
For possible solutions, please see the following:

Disconnecting the TP-Link router from the modem (the piece of hardware supplied by your Internet company), then only connect your computer to the modem directly. If your computer cannot get a stable connection from your modem, it indicates the issue is on your modem or Internet Service.
If there is no problem with the modem, please try the following tips:
Check that the Ethernet cable is connected securely to the WAN port on your router and that the cable is not loose or attached poorly. To check if there is any problem with the Ethernet cable, replace it with another Ethernet cable and see if the issue persists.
Try to change DNS servers on your router. (You may refer to How to Change the DNS servers on the wireless router and DSL modem router (New UI)?)
Upgrade your router to the latest version. (You may refer to How to Upgrade the Firmware on the TP-Link Wi-Fi Routers?)

Troubleshooting Guide of DDNS function on TP-Link Wi-Fi Router, LTE Gateway Router or Deco Router
DDNS, most commonly known as Dynamic DNS, is an automatic method of refreshing a name server. It can dynamically update DNS records without the need for human interaction. It is extremely useful for updating IP address records when the public IP address changes.
If you have any problem using the DDNS function on TP-Link Wi-Fi Router/LTE Gateway Router or Deco Router(we will just call it Router in this article), before troubleshooting, please refer to the following tips to confirm if it is really DDNS issue.

Tip 1. Will the DDNS domain name always be bound to my Router WAN IP address?
Please note that the DDNS domain name is bound to the real public IP address, if your router’s WAN IP address is a private address or CGNAT address, the IP address bound to the DDNS will be different from your Router WAN IP address.

In that case, the remote access to the router or local server will not work even after you configure port forwarding on the Router, because it means there is another one or more NATs in the front of your router, you will need to open related ports on the front NAT products as well.

Note: For LTE Gateway Routers working on 3G/4G Router mode, it uses SIM card to get internet access, if the WAN IP is not public IP address, it means the front NAT is on your ISP side, so you are unable to open related ports on front NAT product, please contact your ISP to see if they could assign you a public IP address directly.

Tip 2. Methods to tell whether it is a public IP address or not

Private IPv4 addresses have the following class configurations:
Class A IP addresses: from 10.0.0.0 to 10.255.255.255
Class B IP addresses: from 172.16.0.0 to 172.31.255.255
Class C IP addresses: from 192.168.0.0 to 192.168.255.255
Apart from the private IP addresses in the above 3 classes, there is another range of IP addresses, which looks like public IP address, but Carrier Grade NAT (CGNAT) address. They are from 100.64.0.0 to 100.127.255.255, which are usually not real public IP address either.
Or you could also google your public IP address on a client device connected to the Router, then compare it with the Router WAN IP address. If they are the same, it means the Router WAN IP is a real public IP address, if not, it means it is private IP address or the CGNAT address.

Tip 3. How to tell whether my DDNS is working or not
Via nslookup command For example, if your DDNS domain name is xxxxx.tplinkdns.com, then you could input “nslookup xxxxx.tplinkdns.com”, and then press enter to check if the correct IP address can be resolved, if so, it means the DDNS is working now.

Note : correct IP address is your public IP address, it might be different from your Router WAN IP address, which depends on whether your Router WAN IP is a public IP or not.

Troubleshooting steps if you are unable to access the local server remotely via the DDNS domain name
Step 1. Check if your Router WAN IP address is public IP address or not.
For example, you could check Deco router WAN IP address via Deco App: More->Internet Connection->IPv4

Step 2. Check if the port forwarding rules are configured correctly on the Router for a local server.
Note: If you are trying to access the router web interface remotely instead of local servers, you should check if remote web management is configured correctly on the Router.
Step 3. Check if the DDNS is bound to the correct IP address via nslookup command mentioned in Tip 3 above.
Step 4. Check if you could access the local server via the current public IP address instead of the DDNS, which could confirm whether port forwarding really works or not.
If it cannot be accessed remotely via a public IP address either, please troubleshoot the port forwarding feature first: Why port forwarding feature is not working on my Wi-Fi router or Deco

Step 5. Contact TP-Link Technical Support and provide us with the following details:

How to set up Wake-on-LAN on wireless router

What is Wake-on-LAN?
Wake-on-LAN (WoL) is an Ethernet or Token ring computer networking standard that allows a computer to be turned on or awakened by a network message. The message is usually sent by a program executed on other devices. It is also possible to initiate the message from another network by using subnet directed broadcasts or a WOL gateway service.

Hardware requirements
The mainboard and wired network adapter must support Wake-on-LAN feature.

Software requirements
WakeOnLanGui,LanHelper for Windows or RemoteBoot for IOS.
Here we take RemoteBoot as an example.

Set up steps

Enter BIOS when start up the computer. Then enable ‘Resume by PCI Device’ and ‘Resume by PCI-E Device’. Usually this option is in power management menu.
Turn on the computer and go to Control Panel–Network and Internet–Network and Sharing Center–Local area connection–Properties–Configure–Advanced. Then Enable ShutDown Wake-On-Lan, Wake on Magic Packet and Wake on pattem match.

After the settings are done on the computer, we need to do some setting on our Router.

Wake up a PC on WAN side

Check MAC address and IP address of the computer need Wake-on-LAN. We call it PC 1 here.
Set IP&MAC binding of PC 1 on our router and enable IP&MAC binding function.
Set Address reservation for PC 1 on our router.
Open a port for PC 1 by port forwarding function such as virtual server. Here we open port number 3000.
Now we check the WAN IP address of the Router PC 1 connected. Here the WAN IP is 113.88.198.136 .
Note: The WAN IP address is a dynamic IP usually and it may change at any time. In this case, you may try to set up the DDNS (Dynamic Domain Name Server) on the router following the FAQ. On the RemoteBoot app, the IP will be a domain name you registered with DDNS instead of the WAN IP.
Run RemoteBoot app on iPhone from the WAN side. Then fill in the information like below and click BOOT. You can see PC 1 will start up after you click it.
