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:  

1. 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.  

2. 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.
