Raspberry Pi 4B not connecting to wifi. No IP address

[NewGradRN]

Hi all, I am now in the software installation part of my build. Using Mac, I followed the raspberry pi and LDO setup procedures including assigning host name, user name, password, internet SSID and password, Time zone, etc. Then I inserted the SD card into the raspberry and turn on power. The boards lit up but it does not connect to wifi. Looked up the devices connected to my wifi and it is not listed. Has anyone experienced the same issue? Can you share how you solved the problem ? Thanks

Hi there,

Just did a bit of research and came across this. Hope it helps. This is from the files on the boot section of the raspi's boot disk.

 

WiFi-README.txt

Thanks, I tried it in several ways still did not work... 

LDO instruction says choose raspberry pi Other, Raspberry Pi OS lite 32 bit did that and also tried 64 bit. Enabled SSH in service... no luck.

Tried the wpa_supplicant.. no go. Below is what I put in...

 

          ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
          country=US
          update_config=1

          network={
                         scan_ssid=1
                         ssid=MySSIDname
                         psk=Mywifipassword
                         key_mgmt=WPA2-PSK. (this line I tried WPA or WP2)

 

For some reason, it just won't connect to wifi. Could it be that I got a bad raspberry board?

Found 1 entry with the same problem and Raspi board except his is wired, and his problem was having MAC filtering on. Checked mine and they were disabled. Checked and double checked SSID and password is correct.

Additionally, is it normal for the 4.3 TFT screen to be not on when power is on? Thanks

If it were me, I would grab a blank SD card and using the official Pi imager...

Select your Pi (Pi4B)

Select Pi OS (Lite 32 bit)

Select Pi OS (other)

Then select "Raspberry Pi OS Lite (32-bit)"

 

Now choose "NEXT" and then "EDIT SETTINGS"

 

Enter in all of your WIFI and other info.

 

Save, Flash, Insert and power up.

You should 100% be connected to your WIFI.

If it doesn't then the hunt continues.

I know this is like 5th grade level explanation, but I want to make sure you install the version of Pi OS that "WORKS BEST WITH KLIPPER".

Because the best way to install Klipper is using KIAUH and the best Pi OS to start with is the Lite 32-bit version.

Couple other things... If you bought a Pi4B with 16gig RAM... you will have memory leak problems, if you have an SD card larger than 64gig... you may have problems.

If the screen doesn't turn on with the Pi then the cable is probably inverted on either the Pi end or display end or both.

[NewGradRN]

That is exactly how I downloaded the raspberry OS. Followed the LDO V2 kit wiring guide for 2.4 revD. Also looked into the article about using SSH. Only after several tries did I venture to trying in choosing pi OS lite (64 bit). 

I am using the 32gig micro SD that came with the kit.

Thank you, thank you, thank you... the ribbon cable connected to the display is indeed reversed and it is now on. And, it seems that the problem not connecting to wifi is related to the inverted ribbon. I did not see any green light on the raspberry before I inverted the cable. I guess the raspberry never booted so it never tried to connect to wifi. Just to make sure, I ping it on my Mac and it is connected. Thank you again... Now to KIAUH...

Programming question please.. I am installing Klipper and it is asking "add user to group now y/n" not quite sure what group I am being added to.. do I need to say yes? Thanks

Cannot recall being asked this as I normally just flash with Mainsail OS, which installs klipper. Answering "yes" would be the best option. Cannot see that that would cause an issue.

That question comes up when you want to run multiple machines to run on the same system (Pi, PC, etc.). I haven't encountered that question installing Klipper but then again, I haven't done a full on install from scratch in close to a year, so things have probably changed.

FYI, it's best to stick to one thread when asking a question. That way the discussion stays in one place.  

[NewGradRN]

Thanks, and yes my bad... I'll stick to one post. I found that the MCU problem was because I have not added the ID for the boards ie Leviathan, Nighthawk, and the Beacon on the printer.cfg. Right now it made it through MCU then Z something error, then it is now bed mesh min error. I have been looking at available Voron printer.cfg I can find and trying out what they have. For the Beacon, I copied and pasted a generic beacon config in their documentation and is now combing through it. One error at a time and I'll get there sooner or later.

[Penatr8tor]

Funny... I'm doing the same setup on my 2.4 currently...

@NewGradRN you'll need to do a... 

ls /dev/serial/by-id/*

...to get your MCU, Nighthawk and Beacon ID's.

I was just on the beacon site running thru the quick start and they don't have that in their instructions. They just say... Input your ID here...

And believe it or not... I'm setting up a Leviathan with a Pi 5B, Orbitool V2 and a Beacon RevH

I started with the Leviathan printer.cfg and making alterations based on the Orbitool and Beacon.

[NewGradRN]

Thanks, yes I already found the device IDs and plugged them in to the printer.cfg. I uploaded the premade printer.cfg for the 2.4 RevD but can't fully use it because of the mods I made including the Beacon and placement of the endstops. I am trying to figure out what to do to fix one errors.
