tp-link WiFi Router(s) and Heat Related Issue
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Dear tp-link Support & Engineer:
There are many users reporting tp-link WiFi routers with heat issue along with WiFi reliability. Please investigate the WiFi Transmit Power feature. Perhaps by setting this parameter to high, the router is consuming too much power, causing the router heat issue. The increase in power consumption and heat possibly causes the router and WiFi to be unstable, i.e. router reboot and WiFi dropping.
Thank you for your attention in this matter.
The below is what I normally posted for users to test, perhaps engineering can perform and observe the power consumption.
Attempt the below, one at a time, to observe the outcome:
- Feel the router, if the router is hot or lots of heat coming out, use a fan to cool the router, regular or USB fan.
- Set the WiFi Transmit Power to low (if the current setting is set to high), and see if this helps with the reboot.
- Observe the heat output from the router when Transmit Power is set to low versus setting of high.
- Turn the WiFi off completely and feel the difference of the heat output and observe router stability.
Place the router on a USB fan like the below:

Hello, thanks for reporting the heat issue.
Please attempt the below to observe the outcome as suggested by Godzilla:
1. Put the router in a well-ventilated location or mount it vertically on a stand that permits the free flow of air, and use a fan to cool the router, a regular fan or USB fan is fine.
2. Set the Wi-Fi Transmit Power to low (if the setting is currently set to high), and see if this helps with the reboot.
3. Turn the Wi-Fi off completely and feel the difference of the heat output.

@Kevin_Z it doesn't matter if router is with wi-fi off or on, it is hot all the time, before I have installed it on the wall, i have tested it for 2-3 days to see if that heat is somewhat caused by the high power wi-fi or wi-fi at all. Router is hot no matter there was no active connections to it, i even tried with just 1 client on it, without lan connections etc..

I too tested AC1200. Which had the latest firmware from the tp-link site. As per the mail company sent. I kept in (more) ventilated area, but as I start watching hi-res video via stream it(router) starts heating up. I even checked my wall socket connection, but all same result. All the while keeping my transmitting range too low. The heat issue remained. Until I shelled some more bucks for the cooling pad, now the heat is in check but occasionally it rises as per my usage. The mail suggested to bring it to the tp-link center, with growing Covid cases in my province, I am keeping that option later. I tried your option too.
Either there is some firmware problem or device issue which passed their testing case. Just waiting for the pandemic to end before something happens to the router.

Bought this router last week and was about to plug in a network drive.
The amount of heat scared me and I immediately unplugged the device to prevent causing it a fire.
I liked the router but sending it back. Not about to have my house being burned to a crisp.

Hi, thanks for reporting the issue you are experiencing. May I have the exact model number of the AC1200? Is it Archer C6 or Archer C1200? It is suggested to try the previous suggestions that given by Godzilla, and you can also power off the router when there is no need for the internet.

Thanks for your reply. Here are my details for the deice below :
Firmware version : 2.0.2 Build 20180118 rel.38979 (EU)
Hardware version: Archer C1200 v2.0
Model name in box is same above (i.e Archer C1200) with name <AC1200 Wireless Router>
Hope the above information helps.
I have applied the advice by Godzilla . The router stays off at least 2 -3 hrs in a day excluding the night off. As per advice I lowered the transmit power, now we all have to use the router and get the internet in close proximity to each other 
. It will be very helpful if the solution came as a software update. Although I am managing it with a Laptop cool pad I am hoping for a permanent solution.

@Solla-topee This is an expensive router and could be a fire hazard. it is not appropriate to tell your customers to be patient when you know your product is flawed. Please advise where to send the unit back to as this is dangerous.
