Archer C7 v5 is emitting a hidden network
Hello,
my Archer C7 v5 is emitting a hidden wifi network that I can't explain.
According to a wifi network analyzer, it's MAC address is identical to the MAC addresses of the 2.4 and 5 GHz network, except that the first 6 entries are AA:DA:C4 instead of the TP-link associated 98:DA:C4. The hidden network has same maxium speed of 216.7 Mbps as the 2.4 Ghz network and allows authentication via WPA2 PSK-CCMP.
The hidden network exists independent of the operation mode (Acess Point or Router) and also if both the 2.4 GHz and 5 GHz networks are disabled.
Any ideas what that is?
Best,
Frederik

Thanks for asking again. The official firmware to disable the Onemesh option is still on the way, you may need to wait it with patience. While if you do need it right now, we can provide you a beta version. Please confirm.

Please send me the link to the beta firmware
My current version
1.1.7 Build 20201010 rel.49458(5553)
Archer A6 v2.0
my main concern is to stop the hidden ssid because of it i lose connection to couple of the mobile devices.
regards,

Thank you for this. I did get the file and I can confirm I was able to successfully upgrade A6 v2 to:
1.1.8 Build 20201110 rel.52599(5553)
I also can confirm that the ghost/One Mesh hidden SSID is gone now when in AP mode for both 2.4ghz and 5ghz. I did not revert to routed mode to try to manually toggle the One Mesh option.
Do you want me to test routed One Mesh toggle? Do you have an ETA for this release to the general public?

Please check my below post, you can try the beta firmware for your Archer A6US 2.0.

Hello, thank you both for sharing your opinions on this issue and thanks @Aquafox a lot for summarizing this feedback, really appreciate that.
Update on 2020-12-24:
For those Onemesh routers, there is currently no switch on/off feature for the hidden SSID, we will soon release a new official firmware to add this option to allow you to disable/enable the Onemesh. The good news is this feature has been available for the Archer A7 and Archer C7, you can update your router firmware to the latest then confirm.
For others models, such as Archer C6/A6, if you don't want to have the hidden SSID as well, the current workaround is upgrading to the below beta firmware:
For Archer C6EU V2: https://static.tp-link.com/2020/202010/20201030/ArcherC6v2_eu-up-ver1-3-6-P1[20201030-rel60104].zip
For Archer A6EU V2: https://static.tp-link.com/2020/202010/20201030/ArcherA6v2_eu-up-ver1-3-6-P1[20201030-rel60104].zip
For Archer C6/A6US V2: https://static.tp-link.com/2020/202011/20201110/ArcherA6v2_us_tw_c6us-up-ver1-1-8-P1[20201110-rel52599].zip
For other models, we will add this feature in the near future. This will take some time, however, we hope you could wait patiently.
Note: We as always strongly recommend our customer upgrade their TP-Link devices to the latest official firmware, you can try the beta firmware posted by our TP-Link Admins/Officials unless the official firmware doesn't resolve the issue you experience.
Thanks a lot.

With wifi analyzer, we can find that Archer A7 v5 / Archer C7 v5 (both with latest firmware) has 2 SSIDs on each band. Actually, one of them is the normal SSID, which can be detected and connected by the wireless devices; The other is the hidden SSID, which is used to build up the one mesh wireless network system

@Aquafox I have no idea
I worry whether this will have effect on network performance (or maybe hardware life) or not, especially because it's intermittent.
If the Hidden SSID just stays there without disappearing every few seconds, I would have less doubt.

I noticed on the beta software, the A6 v2 is creating unnecessary DHCP requests, like every 30 seconds.
Not only are they too numerous, but they should be not happening as the interface is set to a static IP on the A6 v2. DHCP Server is set to (auto). If I turn DCHP Server fully off, then this goes away, but it breaks DNS across the A6 v2 :(
The A6 is set to AP mode and it not the main router. Please forward this to the development team. Thanks.
The main router is reporting the excessive DHCP in it's own logs:
