Have any of you had any experience debugging  Raspberry Pi WiFi connection?

Never needed to. It just worked. But I started on linux long before wifi was even around, so what's the issue?

One problem I've found with it connecting to wifi is it can't connect to hidden ssid.

What problem you got?

I bought a pi 3 with a 7" touch screen for my nephew, and when we assembled it the screen worked but the wifi stopped working. I Googled the issue and updated the OS but no luck yet.

When I do an "lsmod" I see the name of the wifi chip, but when I do "iwconfig" the adapter is not listed. I rebooted a couple of times after the "apt-get update" but no luck.

So you had the wifi working before you attached the screen?  And this is the built in wifi?

[Jim Owens]

yes, and yes.

My Pi3 did this when I use a wireless bridge chip in the GPIO for wireless temperature/sensors.    For me, my wireless device name was changed and thus my wlan configs were looking for the wrong device name.   This happened every time I had a power outage or did an improper shutdown.      For me it was a problem because I ran my Pi headless.   I ended up using the Ethernet connection and reloading Raspbian from scratch and recompiling code.
