The Phoenix has 2 different WIFI adapters to enable high quality network.
After the scan, it will display the found networks with their respective names, for example: "M2000 / wlan0 / 54 / 64".
Here M2000 is the name of the network, wlan0 indicates the WIFI adapter, 54 is the signal strength and 64 is the channel of the network. If you see your network twice (once with wlan0 and once with wlan1), then please select the one that indicates the highest signal strength. The signal strength should be at least 50, otherwise the network is too weak. If you don't reach this value, you have to place the chess computer closer to the network router.
If the WIFI adapter displays a "-" instead of the signal strength, this does not mean that no connection is possible.
