But I’m noticing that I lose my WiFi 5G connection sometimes. Last night my 5G connect just get disabled and I need to enabled if again on LuCi Dashboard. Sometimes I notice that the 5G connection just drop for some minutes.
I didn’t notice any problems with my WiFi 4G or the ethernet.
So, my question is: How can I debug to find where is the problem? There are some log files that I can check?
I was thinking about power issues with my cable and charger, but is the same that I used before in another project. And my lan and 4G connection don’t show any problems… So I’m kind of lost here.
To find system logs, visit 192.168.3.14 in your browser whilst connected to PiFi then:
Sign in with whichever password you set in the app during setup
Then tap Status > System Log
Couple of quick things that would be handy to know:
When you say WiFi 5G - does this mean the 5Ghz access point from your Raspberry Pi (by default, PiFi 4 Setup but possible renamed)?
When you say WiFi 4G - what is that network? (2.4Ghz network? Is this on Raspberry Pi or TP-Link?)
Are you using PiFi USB also or just the software-only version?

Pro Tip: You mentioned power, and that is a good place to start, Pi 4 without any accessories - such as USB peripherals or HATs, needs a minimum of 5v3a adapter or higher. With accessories, higher is better. And networks dropping due to insufficient power can certainly happen.
I believe that your HAT is being confused for a USB adapter which has led to the app offering you to turn on 2.4G network.
Here’s why:
Raspberry Pi only has one wireless radio, it can broadcast either 2.4Ghz or 5Ghz (by defaults it’s 5Ghz which I’d recommend)
If PiFi App showed/allowed you to try and enable a 2.4Ghz network, and you have no USB adapter I assume it’s mistaking your HAT as an adapter and that’s why that option is showing
If you’re stuck on 2.4Ghz or it’s unstable I’d recommend doing a quick factory reset and sticking with the default 5Ghz network (of course you can name it whatever you’d like)
But it can’t broadcast both 2.4Ghz + 5Ghz at the same time with no additional wireless hardware. It can do that only with PiFi Kit - I assume the app may have mistaken the HAT as an adapter.
