Trouble bridging to wifi

[John Regennitter]

I am having trouble getting over to my home network.  Process :

1. BOOT  rpi

2. Connect to digipi hotspot

3. Key info into web browser for 10.0.0.5/wifi.php

4. Chrome responds with home wifi ssid/pw screen

5.  Keying ssid=wirelessjr and it's alphanumeric pw

6. Press save.  Unit comes back with restart direction and reference to "in the next few moments......      I press restart

7. Wait forever

My hw=rpi zero 2.   Network is google mesh network.  Config is digipi 1.9.4

I tried:

1.  Turn on guest network ssid=guest.  No luck

2.  Loaded rpi image new card and boots okay.  Joined same network as 6 above easily

3.  Created phone hotspot and tried the process again.  Failed as above

Any help would be appreciated.  Tks.  JR

does the "DigiPi" wifi hotspot reappear after you [restart]?  If so, it didn't
connect to home wifi.

if you have the little screen it will display the current IP addres and/or hotspot status

If DigiPi hotspot doesn't reappear, then it's on your home wifi and you might interrogate
your router as to what IP was assigned to DigiPi and visit that.


not sure if it helps,

Tks.  Digipi hot spot returns to both 1.3 inch screen and available for login on tablet a 2nd time.  I also noticed that the small screen showed online for several seconds and then dropped back to hotspot.  

Small screen displays 10.0.0.5

So trouble connecting.....

[Craig]

yah, that fully indicates it's not connecting to home wifi

5G?  2.4Ghz?   5G may not work on all Pi's

Wired connection?  if so, you can always edit /etc/NetworkManager/system-connections/wlan0.nmconnection

then it's between raspberry Pi OS and your router

2.4 I thought was rpi zero restriction.   That was freq it used on rpi Linux boot. 

Router does both.   

Any possibility of residual address in rpi?  I have played with several option for ssid.   Could recut using etcher tool...

Also didn't see wlan0.nmconnection when I looked at digipi image.  Can only find .dtb, overlays, and .elf

What about trying 1.9.3?

I think you're right about Zero being 2.4 ... I only use 2.4 here at home, goes farther.

I'm not sure what a residual address is.   Etcher/imager should not modify the image in any way,
as they still assume RpiOS still uses wpa-supplicant for wifi.

wlan0.nmconnection is on the Linux filesystem on the SD card, but Microsoft hasn't
innovated the Linux filesystem yet, so it's not visible.  You'd need a hard-wired ethernet
setup, and ssh in, or get ext4 filesystem tools to mount the linux (second partition).
You could use putty/ssh on your pc to get a login prompt on digipi also.  you could
even hookup a keyboard/monitor to digipi.

... or figure out why Raspberry Pi OS doesn't like your router -- it's not just you either.

It's a zero 2 W, right? Because that would matter, is the W was missing.

I ordered zero 2 w via Amazon.  Looks like the board pic of zero 2 w seen on rpi.org site.  

Thanks for help.   Is there any logging available to diagnose reason for failure to join?

When booting on standard rpi os image where i put login and pw in during cut of SD card, I am able to join network easily and can download updates etc

Not sure of next steps to try

Thanks all for help

Hi John,

You could connect with a pc (DigiPi hotspot), visit http://10.0.0.5/, click Shell, login:pi, password:raspberry and directly edit
the Raspberry Pi Wifi configuration file:

sudo remount
sudo nano   /etc/NetworkManager/system-connections/wlan0.nmconnection

The ssid password are both in that file, that's how Raspberry Pi does wifi.  DigiPi just
pokes your info in there.

I am having exactly the same issue. I can connect to the Pi direct, but not through my home wifi. The Pi is a Zero 2w. I have tried the card in a Pi 4B and have the same issue. Although I can us Ethernet on that.

The password is only letters and numbers so no issue there. Another observation is I have three SD cards:

One with Pi OS, connects no issues at all. 

One With DigiPi. Direct connection fine, but not through Home Wifi.

Pi-Star, same issue as DigiPi

Any help would be appreciated.

Thanks

I solved my problem with a 2.4 wifi extender that limits signal to 2.4.   Apparently Google mesh network was interfering with connection to digipi and network.

So now fixing config issue.   Info on YouTube is helpful to operate unit.

Same issue here, and I’m sure quite a few more people have this problem.  I’ve gone through the same process as John to get this on my home wifi and experienced the same results.  I’m trying to make this work with an Rpi 4, Xfinity Home wi-fi and an iPad to start.  Anyone else have those variables in common?  My end goal is to take this portable and run it off my iPhone hotspot.  So, if anyone has suggestions there, that would help, too.    

Full Disclosure:  I don’t have the programming kung-fu that many others have, so be gentle.  I’m lucky to find the on switch most days.  

Thanks

You guys might try setting your regulatory region/country,

Shell,  login:pi, password:raspberry

sudo remount
sudo raspi-config

Localisation[sic]-Options -> WLAN Country


It's "unset" by default, but this really limits channels/power and might cause these types issues.


you can also use "iw reg set" or "iw reg get"


pi@digipi:~ $ iw reg get
