What if TP-Link Router Disconnects from Internet?

This Article Applies to:

TP-Link Routers

Issue Description/Phenomenon:

Some customers may find that the router keeps disconnecting from the internet/modem, the internet LED on the router changes to red/orange, and it will recover automatically after minutes. Manually powering off and then powering on the router can also get the connection back. This article aims to provide solutions to the issue.

Troubleshooting Suggestions:

1. Check and ensure the internet line or ISP modem is stable, bypassing the TP-Link router. Connect the PC directly to the ISP modem (or internet cable from the wall), test and monitor the internet connectivity, and ensure you have a stable connection.

2. If the modem internet is stable, please connect the router back to the network, and ensure the Ethernet cable going from the ISP modem to the WAN port of the router is securely connected. Try with another Cat5e/6 cable or change the port of your ISP modem, to where you're connecting the TP-Link router (if possible).

3. Check and ensure the router firmware is up-to-date.

4. Login to the router web interface when there is no internet, and check if there is still a WAN IP address on the Status page. If yes, go to Advanced > Network > Internet, change the DNS server as follows, then Save and reboot the router to confirm:

5. It's also suggested to clone the MAC address of the computer (or the MAC of the old router) to the TP-Link router if the internet is stable when the computer (or old router) is plugged into the ISP modem directly. Guidance is as follows:
How do I configure MAC Address Clone on my TP-Link Archer Router?

If the disconnect issue persists after checking all the above, it is suggested to comment below and be sure to provide the following information:

1. Model number, hardware, and firmware version of your TP-Link Router.

2. Who is your ISP? What's the model of the modem?

3. What is the WAN connection type on the TP-Link router?

4. What troubleshooting have you done, and what are the results? Send us the screenshots of the Network > Internet page. You can mask the WAN IP and gateway info for security concerns

@Kevin_Z

I am experiencing this issue on an Archer A8 (latest firmware) with Spectrum as my ISP. I don't appear to have DOS Protections in the settings to disable. I have been having a brief disconnect from the internet on all devices once or twice an hour since I got the router.

Here are my logs any thoughts on what is going on here?

Re:[Troubleshooting] Router Disconnects from Internet

2021-09-16 06:36:31

@nicbr

Hello, please check the logs that I highlighted, you can see that the WAN connection between the modem and the A8 is not good, try with another cat 5e/6 cable if the cable is not good.

You can also confirm if you can get a stable internet connection by inserting the cable into the computer directly bypassing the A8.

Re:[Troubleshooting] Router Disconnects from Internet

2021-09-16 15:50:05

@Kevin_Z
I swapped out the modem->router cable but still experiencing the occasional network drops. I will try direct into the modem when I get the opportunity just need to find a time when no one else is on the network.

Here are my logs from the last 24 hours, still about the same.

Re:[Troubleshooting] Router Disconnects from Internet

@nicbr

Since this issue could be caused by the ISP line or modem, please confirm if you can connect to the internet stably by connecting the computer directly to the modem and test for some time when that is possible.

Or you can contact Spectrum to ask them to help check the line and modem logs, they may find some abnormal disconnects if the line is not good.

Tried this above mentioned stuff but still no luck. My router model is TP-link wr820n V2 and my ISP is BSNL fiber. Router is connected to ONU modem. Internet on ONU Modem works as i have tried connecting directly to it with Ethernet cable.

@Serious_joker09

When did you purchase the router, and when did the disconnect issue happen?

What's the WAN connection type on the WR820N? Dynamic IP or PPPoE? Please send us the whole system log on the router, including that before and after the disconnects, don't reboot the router, you may just wait for the internet to come back automatically, or you can login to the web GUI of the router to connect it back.

@Kevin_Z Following is the system log for last 24 hours.

I don't think any disconnection happened when i was asleep. Electricity didn't go off i guess.

Also that issue only happened once yesterday. I tried setting channels manually. Don't know how much longer it will be stable.
