    Just ordered and received Huawei P30 Lite from Amazon.

    Power up and log in WiFi but only detect 2.4GHz Wifi. No 5GHz wifi SSID servers are shown.

    Verify with other Nokia and Motorola and Apple mobile phones, all showing 5GHz wifi SSID servers and log in operating fine.

    scan the internet and found many other Huawei P30 and other model mobile phone has 5GHz wifi problems.

    Is this common defective hardware in these Huawei phones?

    I had the same issue with all my devices, guess what the cause was.. apperantly apple devices in my case XS Max and iPad Pro 11 have some weird interference which caused my P30 Pro and all others to disconnect from 5g. Try turning off all Apple devices and it will work again.

    Is there an option in the advanced wi-fi settings to select 2.4 Ghz, 5 GHz, or Automatic?

    Yeah, I remember this setting on some older phones, but I'm not sure it's still available for Pie (or even Oreo).

    You can scan the Wifi and show the SSID. But when you access WiFi, it scan the WiFi and list the SSID. It does not show which is 2.4 or 5GHz.
    Looking at Huawei P30 Lite spec, it show the WiFi standard is IEEE standard 802.11a/d/g/m/ac. I assume "ac" is 5GHz, right?

    The Brazil variant doesn't have 5GHz wifi (https://consumer.huawei.com/br/phones/p30-lite/specs/).
    Also you can check the FCC approval for LX3A (FCCID:"QISMAR-LX3A"). Every phone needs to be tested for radio emission safety (SAR, DTS tests). LX3A did not list 5GHz wlan, and so it cannot have that antenna built in (even if it would be disabled by software).

    My P30 pro was the same but there is a setting in you modem/router called 'Band Steering' or similar which I unchecked and YES my P30 immediately recognised both 2.4Ghz and 5Ghz signal, so that was my solution, it's not the phone it's the modem/router.
