1:According to your description, the 2.4 and 5G signals or is just disable or the radio signal is damaged, so this is why you cannot see the SSID/Wi-Fi signal and connect to Wi-Fi, but wired must work.
2:What you need to confirm is if your ISP is working fine, so you can follow up the next steps to gain access to enable back the 2.4 and 5G signal for your Access Points.
A:Connect your computer with an Ethernet cable to your Ruckus ICX7150 Switch:
In this example, the Switch is the White box, that can have 8 or 12 Ethernet ports, use any of them to connect your computer.
As alternative, you can connect your computer to your ISP router too.
B:After you connect your computer, this one will be online, search for the next website, which is the equivalent to the APP, but for web browser.(use the same credential that you have for the APP)
C:If you gain access, let's check if the SSID/Wi-Fi is created and check if the 2.4 and 5G signal are enable for that SSID.
Enable the Radios Signal
Select the WLAN you want to configure from the Wi-Fi Networks component and click Edit> Advanced Options > Radio Control>Enable WLAN on>choose all to enable both radios in the SSID/Wi-Fi you choose.
D:We need to also confirm if the Access Points have enabled the 2.4 and 5G signal because can be that the SSID/Wi-Fi is enabled but the Access Points it have it disable, please follow up the next steps.(one is for 2.4 and the other for 5G)
Access Points>click the AP you want to configure> Edit>Radio B/G/N (2.4G)>Enable
Access Points>click the AP you want to configure> Edit>Radio A/N/AC (5G)>Enable
Note: you can use the summary option, which is to made changes in all the Access Points.
