Need help with assigning priority to wifi network
Hello Community,
I’m trying to configure multiple wifi networks to my wlan0 using vintage_net.
I want understand more about assigning priority to the networks. I was able to set priority and observed that network with higher priority is selected. Sharing an example i used
VintageNet.configure("wlan0", %{
type: VintageNetWiFi,
vintage_net_wifi: %{
networks: [
%{
ssid: "TestWifi1",
psk: "Test1234567",
key_mgmt: :wpa_psk,
priority: 2
},
%{
ssid: "TestWifi2",
psk: "Test1234567@sor",
key_mgmt: :wpa_psk,
priority: 1
}
]
},
ipv4: %{method: :dhcp}
})
Referring to above example, I observed wlan0 get connected to TestWifi1
I do have few question related to this
- Is there any limit to priority
- Is there any other method to assign priority
priorityshould always be integer? or it can be string?- I was not able to find any documentation related to this, if someone can point me to any documentation
Thanks & Regards

VintageNetWiFi’s parameters translate pretty much verbatim to those used by wpa_supplicant, so the example wpa_supplicant.conf usually has the best information.
Here’s the relevant section about priority:
# priority: priority group (integer)
# By default, all networks will get same priority group (0). If some of the
# networks are more desirable, this field can be used to change the order in
# which wpa_supplicant goes through the networks when selecting a BSS. The
# priority groups will be iterated in decreasing priority (i.e., the larger the
# priority value, the sooner the network is matched against the scan results).
# Within each priority group, networks will be selected based on security
# policy, signal strength, etc.
# Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not
# using this priority to select the order for scanning. Instead, they try the
# networks in the order that used in the configuration file.
