Hello, I use this router at home. I have 3 EAP 650 access points. It worked well for 8 months. Then, it stopped working. We restarted it, and it only worked for a few hours. We replaced it with a new, identical one. We reprogrammed it completely to the same settings as the old one, i.e., the default settings. The new one does the same thing. It works fine for a few hours, then stops working. The router sees the Internet since we have access to Omada online via the cellular application. However, the Internet network no longer works, nor does the LAN. We are connected to a 400 MByte Technicolor modem, on the Videotron Internet network. To help out, we use an Asus router. With this router, everything works well. However, I want to use the Omada, which has much better performance. Do you have any idea of ​​the problem and the solution?

 

Bonjour, j'utilise ce routeur à la maison. J'ai 3 points d'accès EAP 650. Il a bien fonctionné durant 8 mois. Par la suite, il a cessé de fonctionné. On le redémarrait, et il ne fonctionnait que quelques heures. On l'a remplacé pour un neuf identique. On l'a reprogrammé au complet selon les mêmes paramètres que l'ancien, soit les paramètres par défaut. Le nouveau fait la même chose. Il fonctionne très bien pour quelques heures, puis cesse de fonctionner. Le routeur voit Internet puisqu'on a accès a Omada en ligne via l'application cellulaire. Toutefois, le réseau Internet ne fonctionne plus, ni le LAN. Nous sommes brancé sur un modem Technicolor de 400 Moctets, sur le réseau Internet de Vidéotron. Pour se dépanner, on utilise un routeur Asus. Avec ce routeur, tout fonctionne bien. Toutefois, je veux utiliser l,Omada qui a de bien meilleures performances. Avez-vous une idée du problème et de la solution?

Based on the description, it appears to be a problem residing in your LAN. I need more information on how it loses the Internet. 

For example, do they still get an IP from the router?

Yes, the local network receives an IP address from the router. For example, my PC receives the address 192.168.0.2. Each device receives an IP address, but not an Internet connection.

 

In the default configuration, the DHCP range is 192.168.0.1 to 192.168.0.254. I modified everything to obtain a range between 192.168.0.2 and 192.168.0.254, since 192.168.0.1 is used by the router. Do you think this could be the cause of the problem?

I've attached a screenshot of my configuration.

Everything worked longer than usual, for six hours. We kept our Wi-Fi, but without an internet connection. However, our wireless Tapo cameras continued to work. We had to reboot the router. The devices retained their IP addresses, but without an internet connection.
