2.4Ghz network stops working, but the 5Ghz network works
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Since I bought this Router I have connection problems with the 2.4Ghz network, it is like it is disabled by itself, but the 5Ghz network still works in perfect conditions. I have consulted and changed the device for warranty, I have updated, but the firmware has not worked, nor has the rollback either. I really don't know what to do to make it work, the only way to take it again is to restart the router 2 times a day. I have even tried to do it without a password or security, but even so the 2.4Ghz network does not work. Could you tell me if there is any update error of this model?
Please help me!

Hi, what is the region version of your Archer C6, is it an EU version or a US version? The beta firmware I posted was for the EU version, please confirm.
If your router had been bricked, please try to refer to the below stories to confirm if you can make it alive again:

Is your router model Archer AX50? The beta firmware was provided only for Archer C6 EU v2.0, so it definitely not workable for your device.
Can you describe what is the exact issue that you experience with the Archer AX50? What have you done trying to resolve it? Thans a lot.

@Kevin_Z It's the EU version. I installed your beta build and it bricked the router. I was able to recover it. The current version is 1.3.6 Build 20200902 rel.65591(4555). Hardware version is Archer C6 V2.0.
You think i should try to install the beta build again?

May I know how did you upgrade the router? The beta file should be good, as others can upgrade successfully. If you still experience the disconnect issue with the 2.4G network, you can upgrade the router firmware one more time carefully by following this guide.

Was a solution for this ever found?
I just Googled on issues surrounding 2.4 GHZ not working on TP-LINK. I live in Italy and have to use a modem/router. I have been using the TP-LINK model TD-W8970 which works on the 2.4GHZ and has been very reliable. I wanted to upgrade my system mainly to increase the signal strength in the house with WiFi extenders. So I bought the TP-LINK AC 1200 (model Archer VR400) and bought two extenders AC 1200. The AC 1200 has both the 2.4 GHZ and the 5 GHZ. The 5 GHZ works fine, no issues. On the initial set up, it took me forever to get the 2.4 GHZ to transmit, even though it shows on the router that it is broadcasting and it has been enabled on the setup. So once I got it working, the extenders synced and it was reliable. Had the power in the building go off and I have not been able to get the 2.4 GHZ back - no matter how much resetting/rebooting and messing around with it I do. Again, no issues with the 5 GHZ. So I thought I must have a defective unit, so I bought another AC 1200 modem/router and same issue, cannot get the 2.4 GHZ to work. The replacement one that I bought, the box had been open, but the salesman told me I could bring it back if there is a problem. My feeling is that who had it before me had issues with the 2.4 GHZ also. So I am back on the old TD-W8970 where the 2.4 GHZ (does not have 5 GHZ) works fines, and will be taking back the two AC 1200 modem/routers and the two AC 1200 WiFi extenders unless there is a solution out there. Any help?

I have the same issue. 2.4 ghz network drops out. But my device is the TP-Link Archer C5400 v2.0. I'm in the process of doing an exchange. Someone might want to think about applying the fix for the AX6000 or whatever to the C5400 as well. This just all of a sudden started happening even worse a couple days ago - January 21, 2021. Not good for a 1.5 year old wireless router. It also concerns me that its not for sale anymore on your website, that I could tell.
