No way, sorry. I've never had this problem with other brands, I don't want to write their names here, you can guess. it's not acceptable at all a router gets to defaults for a power outage, thsi is not an hardware failure, it's a corruption of internal settings and for reaction it goes to deafault. It looks that cases happened already, I not the only one, and I'm under shock. Zyxtel is not a reliable company to entrust your businness

Any router, or other equipment, can suffer from power problems

I guess it happened to my friend too, on the mornng he suffered 2 main power outages and after that the problem appeared. This is horrible!! I'll nnever buy a tecnology that lost its settings cause a power outage

Hi Vadym, Please write to the support team, who will help you investigate the issue. support@keenetic.de

Good Morning Ilker, We apologize for the delay in responding. That said, this is a forum, not a support platform. Thanks for reporting the issue and the configurations to resolve it. In my previous tests, it was not necessary to explicitly send the “ip nat Chilli0” command, but we have not yet performed tests in an environment similar to yours, with the UAM server in another LAN segment. As for the firewall rule, the behavior is expected. Traffic between different segments is denied by default, so if you need to reach a resource in another segment, you must add a rule that accepts the traffic.

Unfortunately, there is a bug in the Alpha 3, related to the firmware update process. I suggest that you use the recovery utility described here: https://support.keenetic.com/sprinter/kn-3710/en/21740.html#21740-keeneticos-recovery And then you should be able to update to Alpha 4, where this issue is fixed. The link above is for KN-3710, you can find the recovery utility relevant to your particular model, by entering it's name here: https://support.keenetic.com/ and then searching for "Restore".

The problem occurs periodically. Usually it either connects to all or none. I can provide you with service numbers, but there are a lot of routers, do I need to list them all? The problem usually occurs from a mobile phone on the road, from home, from the office at a certain time.

I had 2 cases, when the KN-1111 router reset to factory settings, 90% of the time it was during power outages.

Hi! Could you please provide screenshots of the errors and service tag of the device (send me in DM)? if the issue is still relevant

Maintenance Notice Dear Keenetic RMM Users, Scheduled maintenance will take place on 10 March 2026 (8:45–9:45 AM UTC). Keenetic RMM may be unavailable for up to one hour during this time. You can continue managing your nodes via the web interface or mobile app. We apologize for any inconvenience.

After installing the Alpha 3 version, I started experiencing issues with firmware updates. On the Hopper, Sprinter, and Viva models, I am unable to install either the main (stable) or the dev versions.

I don't understand you completely, you mean that if often happens that the power goes down the router can itself reset to the factory settings? I guess I got you wrong, this is a no sense. Both router turn on regulary, the only proble is that I can't aquire the extender on the main one

And the power doesn't turn on? If this happens often, the router may be reset to factory settings.

ip nat Chilli0 is not required in usual scenario when traffic goes from LAN to WAN. In your setup UAM is placed on another LAN interface.

Thanks for your reply, I wish you good luck, but I don't thin this will help. I've updated the extender to 5.0.7 but didn't help, I'm afraid to remotely update the maim if it can cause again the reset of all settings, I'll create a big problem. This is really bad for a technology that the user is afraid this happens again, unacceptable

Yes. Today, similarly, 1 of the 2 extenders stopped being seen by the controller. I reset the extender settings. It didn't help. I'll reboot the main router in the evening.

Hi mates, thanks for reading and support. Honestly I'm shocked about this brand, in the middle of the day my friend's restaurant was disconnected from internet, when I came I've noticed the router lost its configuration, it kept only password to log in, WAN IP lost, as well as WiFi SSID, DHCP etc. I've set all back but it doesn't want now to acquire the extension, I've reset it to the factory setting, I press the button but after 2 seconds it goes back doing nothing. I'm really annoyed about that, I don't know the reasons of this problem, what can I do now? Should I reset to factory the main router too? Can be the router's settings got corrupted from the update? I've to go there again.. I guess this is beacause of this damned new 5.0.4 version, why it updated in the middle of the day, I'll for sure disable any future update in this router once this is fixed

Vorrei suggerire l'implementazione di una funzionalità software per migliorare la stabilità e la gestione del Wi-Fi a 5GHz, simile a quanto già presente in apparati professionali (come Ubiquiti per esempio). Attualmente, quando la selezione del canale 5GHz è impostata su "Auto", i router Keenetic scansionano l'intero spettro, includendo e preferendo da come vedo i canali DFS (52-144), soprattutto quelli superiori al 100. Sebbene questi canali offrano più larghezza di banda, a volte la frequenza viene disattivata troppe volte. Il router è costretto a interrompere le trasmissioni per 10 o 1 minuto (come da manuale) a seconda se è canale 100 e superiore o 52 e superiore, causando instabilità. Al momento, l'unica soluzione per l'utente è bloccare manualmente un canale specifico (36, 40, 44 o 48), perdendo però i vantaggi della selezione automatica in caso di interferenze. Soluzione proposta: Aggiungere un semplice interruttore (Toggle) nelle impostazioni Wi-Fi 5GHz: "Consenti l'uso dei canali DFS" (Sì/No). Se impostato su SÌ (default): Il router continua a funzionare come ora, scegliendo tra tutti i canali disponibili. Se impostato su NO: L'algoritmo di selezione automatica viene limitato esclusivamente ai canali non-DFS (dal 36 al 48).

The problem occurs when upgrading the device in the mesh system. The main device receives the update, but update checks cannot be performed for the devices in the mesh. Additionally, the devices in the mesh cannot be reached Keendns.

-Google Translate: Hello, I recently received help from AI while troubleshooting some issues with my router, and it was very helpful. I had an idea about how to integrate this into the system, and I'd like to share this model with you. Adding such a feature would be beneficial. The visual is roughly prepared to help understand the logic. It could be a similar model.

funny. nobody answers here
