Network connection issues can be caused by physical interference or the Wi-Fi access point configuration. In this article, we will first try to reduce physical interference and then suggest some simple steps to troubleshoot the Wi-Fi access point. Reduce Interference Check the distance between the router and the Classe 300EOS with Netatmo (3 m is the ideal distance). Walls and some surfaces can absorb the Wi-Fi signal. If the connectivity problem is not resolved, you should install a Wi-Fi repeater in the room where you want to install the product. It is best if the Classe 300EOS with Netatmo and the router are not: Behind a TV. Near a fish tank. In/under a metal object. Located in a closed cabinet. Near lots of cables and wires. Near any wireless devices. If you have any of these devices in your home, temporarily turn them off and see if the problem is resolved: Laptops, tablets, etc. Wireless printers, speakers, and any other wireless devices. Cameras IP. Microwave (in use). Cordless phones. Basic access point English: setup Restart the Wi-Fi router. If there are multiple Wi-Fi access points (repeater/amplifier/extender) in the network, make sure to set different names (SSID) for each access point. Next, make sure that the Classe 300EOS with Netatmo is configured to connect to the access point with the strongest signal. To do this, go to the device settings menu (wheel at the top left) / Network. Advanced Access Point Configuration For the following steps, you will need to log in to the router's configuration page. Check the router's user manual. Try updating the router to the latest software version. Try setting a simpler Wi-Fi password without special characters. Make sure no MAC filter is enabled on the router (or check that the Classe 300EOS with Netatmo is whitelisted). Make sure access restriction (parental control, etc.) is disabled. Check if the router has a sleep function. If so, disable the function Disable Wi-Fi channel restriction (enable automatic selection) or select channels 1, 6 or 11. If your router is 5 GHz compatible, check that 2.4 GHz is also enabled (Legrand Netatmo Bticino products can only connect to 2.4 GHz networks). Try disabling 5 GHz. Check if UPnP is enabled. It is recommended to use it. Try changing the current DNS servers to Google's (primary: 8.8.8.8 / secondary: 8.8.4.4).
