Archer C6 2.4G band stops working, disable then enable restores
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Recently purchased Archer C6 Router running the latest firmware. On 4 occasions the 2.4G WiFi band has stopped working, devices can connect to it but get no network access. Disabling and enabling the 2.4G band on the admin interface restores the connectivity, the 5G band is not affected, a device connected to it is used to reset the 2.4G band.
I used the chat support service to discuss the issue and the suggestion was to change from automatic to a fixed channel for the 2.4G band, this appeared to resolve the issue but it has happened again today, a phone which only works on 2.4G was showing the WIFI as access denied.
is there anything else I can do to resolve this issue.

Hello, thanks a lot for your detailed info, and thanks again for all of your efforts struggling with this issue on the Archer C6.
May I know how many wireless devices are connected to the 2.4GHz network out of 22? Are all 2.4GHz wireless devices experiencing the same dropout or just some special or old clients? When they got disconnected, is the 2.4GHz wireless network of the Archer C6 still broadcasting or the wireless network is no longer available on all other devices as well?
What kind of "heavy" use do you have on the local clients?
Thanks.
Hi Kevin, thank you for your fast reply!
I have 20 to 22 clients connected to the 2.4Ghz netwerk, at the same time. Security camera's, smart lights, smart switches, android phones and android tablet and a couple of chromecasts. Two google nest mini's are on the 5Ghz network or switch to the 5Ghz if they are connected to the 2.4Ghz netwerk when it goes down.
Yes all clients, newer and older, on the 2.4 Ghz disconnect when it goes down.
The router completely stops broadcasting on the 2.4 Ghz, transmitter is down, no RF signal, it goes off air. Comes back on air after some time but clients can not reconnect.
When trying to watch more than one camera at a time and streaming music, youtube or watch Netflix at the same time the 2.4 Ghz network works approximately 10 minutes without issues before it goes down.
When the 4.2Ghz is not used that heavy it stays on air without problems much longer.

I have never connected the heavy use with the problem so far, interesting thought.
I will do some penetration testing later this week to see if i can force a disconnect.
Ill report soon.
Is there a way to get a system logfile?
Maybe we can find something in there...

Hi Kevin
Sorry to let you know nothing changed. Exactly same behaviour. 2.4Ghz down within ten minutes.

I'm not using my C6 V2 for a month, and I'm using the router provided by my fibre ISP (slow, but 100% stable), waiting for a real solution to these problems. But I can confirm that I think the problem was caused by a chinese unknown brand tablet of my children. That tablet "talks" without problems with all routers for a year, but C6 doesn't like it, and after some time streaming, 2'4 band stop responding.

I have already packed mine C6 to send it back to retailer but then I received a TP-LINK message:
"To better assist you, this case is escalated to our senior engineer who will help you solve the problem more efficiently. Please be aware that our senior engineer will contact you via email within 1 business day, then they may ask your agreement for calling back or remote assistance to solve the problem in an effective way."
Today they sent me this:
"Now our RD has found one issue may cause the 2.4G connection issue, and releases a new firmware, would you mind trying it?"
And the download link to: ArcherC6v2_eu-up-ver1-3-6-P1[20200804-rel59384].bin
Lets start it all again then :)
