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!

If the signal is not stable, you can try to modify the wireless settings on the MR6400 first, you can refer to this article to eliminate the interference that may affect the wireless signal:

Hi. I upgraded my Archer C6 EU with beta firmware, but issue with 2.4GHz network still exists. It is on both networks: normal and for guests. After couple hours I am unable to connect to those networks, after router reboot it starts working again for couple hours. I am trying with my laptop, phones (android and iPhone). Also my smart home devices using 2.4GHz network and they become disconnected. 5GHz network working without issues.
Router is broadcasting 2.4GHz networks all they time, just I can't connect.
I tried changing 2.4GHz network settings as described in FAQ, but it didn't help.

Hello, if the 2.4G wireless connection is not stable on the C5400, please try some basic modifications and see if any helps:
1. Can you confirm if the 2.4G signal is disappearing, or it just drops, but you can still see it? How many devices need to be connected to the 2.4G network, are they dropping at the same time?
2. How did you recover the connection? Do you need to restart the C5400 by powering it off then on?
3. Please check and try to change the 2.4G wireless settings on the C5400 web page, run a Wi-Fi analyzer to verify which 2.4G channel is clearer, then try the channel on the C5400 to that one. You can also change channel width to 20MHz, change security to WPA/WPA2-Personal, WPA2-PSK/AES, then reboot it and confirm.

How many devices are connected to the C6 2.4G network? Are they disconnecting at the same time? Are they any error message when they failed to reconnect?
After upgraded to the beta firmware that we provided previously, have you disabled the Onemesh feature on it? You can also disable the NAT boost on the web interface (Advanced-System Tools-System Parameters).

At the beginning Archer C6 was used as access point, because I used my ISP router. At that time there were just few devices connected to device via WIFI.
Currently I resigned from ISP router and using my TP-Link Archer C6 as the only router and WiFi device. There are 22 devices connected via WiFi, 18 are using 2.4 GHz network (9 using normal WiFi and 9 using guest one). All devices disconnects at the same time. When I am trying to connect via phone, then it says Connecting and just drops without any error message (I don't get message, that it tries to get IP address from router, etc.). I disabled Onemesh after upgrade. After your post I disabled NAT Boost.

I am experiencing the same problem an my Archer C60. Installed the latest firmware today but the problem persists. It seems the 2.4GHz network just 'disappears' at times. I have about 10 clients, mostly home automation switches, connected all the time, but they are all very low bandwidth devices. Usually I can fix the problem by disabling and the re-enabling the 2.4Ghz radio then all the clients connect again. I have tried changing the channel, bandwidth to no avail.
I have a suspicion the problem may be related to the number of clients since it seems to be getting worse as I add more clients. I am at the point now where I am seriously considering just dumping this router, or maybe try reflashing with openwrt
Any help wil be appreciated
