Upgrading via dietpi-update appears to wipe existing wi-fi settings out.

Using the network configurator shows the (correct) entered settings for SSID and Password, but the default IP is assigned, despite DietPi claiming to be connected to the corrct SSID.

Mounting the card on MacOS, this is the dietpi.txt file that is extant (after the upgrade and after setting the SSID and password via the configurator:

"#Modifications to /boot/* files, will not be saved when powered on.
#Please ensure you edit from the DietPi-RamDisk location /DietPi/*

#NB: This is intended for advanced users, unless you know what you are doing, do not edit this file. Please use the DietPi programs instead.
#NB: Do not remove uncommented lines, as the items are scraped by DietPi programs, on demand.

@GrahamGIGA

Hi Graham,

Many thanks for the report 👍

In dietpi-config under WiFi options, please can you toggle:

• Change Mode: DHCP
• Save changes

Once completed, WiFi should now be connected to network, at which point please can you send me a bugreport:

Also, can you remember which version of DietPi you were running, prior to the update?

---

The dietpi.txt options are only used on 1st run, after which point dietpi-config must be used to make any changes.

Very strange this has switched to STATIC IP during the update. I can only suspect $G_DIETPI_INSTALL_STAGE was not updated to 1 during your 1st run, however AUTO_SETUP_NET_USESTATIC=0 and only triggered during 1st run in pre-boot. Regardless, i'll do some local testing and see if we can replicate.

[MichaIng]

@GrahamGIGA
Thanks for your detailed report.

€: Lol same time answer :smile:

Note that we changed where to set WiFi SSID and credentials to dietpi-wifi.txt on first boot. I have to check whether we correctly port existing settings from dietpi.txt on update.

If you set WiFi settings afterwards and you don't choose DHCP, but static IP, use the "copy" option to copy currently applied IP and such into static settings. Usually DHCP is what you want (first) to get correct IP range, mask, gateway and DNS server from AP (router), then copy the applied settings to static IP, if you don't want the DHCP server from then on.

[GrahamGIGA]

Hi Dan,

I had missed the change to static - thanks.

There is something very odd going on here. I now have the Pi working again, with an assigned IP of .252, which is fine EXCEPT that the DHCP server [should] allocates a predefined IP based on the device. The setting in the server appeared to be correct, but was ignored.

I'll run the pi as is for a couple of days.

You have bug report: Bug report sent, reference code: a1fceb05-eda7-4eaf-9b99-38e5d4cfc4ad

To your question of prior version, I am unsure but THINK it was .14. I have two that updated fine (from .16) and two that have not - they are both older versions.

I do find that the wifi setup and settings (UI) are poorer than they used to be and it is much easier to make a change that is not intended.

One final thing: during the changing of wireless ettings, after one reboot the system insisted that I must Sudo dietpi-config. Only the once, the next time it worked as expected, i.e. from the command line.

Cheers

[GrahamGIGA]

One final, final (?) comment on wireless. On the 3B there is an on card wireless and I have a Rosewill USB dongle plugged in. This is for reliability, the onboard was (is?) poor in earleir versions. When I diasble onboard wifi what am I disabling - the built in or all?

The dongle isn't distnguished in the setup menu.

Cheers

@GrahamGIGA

Hi,

IP of .252, which is fine EXCEPT that the DHCP server [should] allocates a predefined IP based on the device

You'll need to verify the MAC address of the USB WiFi device matches .252 in the router control panel. Failing that, i'am unsure as router setup varies.

One final thing: during the changing of wireless ettings, after one reboot the system insisted that I must Sudo dietpi-config.

Sudo is only required if logged in with the dietpi user dietpi. If you login as root, sudo is not required.

This is for reliability, the onboard was (is?) poor in earleir versions.

Onboard WiFi on the RPi is not as good as some USB dongles, however, as long as the range is acceptable, onboard WiFi is stable.

When you disable onboard WiFi in dietpi-config, this will disable the onboard RPi brcm module from loading. Essentially preventing it from being available.
Once disabled, you will need to re-setup WiFi in dietpi-config as the USB wlan adapter will change to wlan0.

I believe the main issue here is confusion in the dietpi-config UI for WiFi network setup, as I'am unable to see any bugs our end at the moment.

[Fourdee]

Current image is v6.17 and that is all I have on backup at the moment, so unable to test v6.14 or lower images with this.

However, I did extensive testing with the wifi-db switch prior to release and everything passed. RPi image was then updated at v6.17 and includes the new wifi-db system.

The v6.15 patch to wifi-db only sets the db, not static IP. And it does appear to have worked as existing WiFi creds are visible in this image:

[GrahamGIGA]

Hi Dan,

Well the system definitely changed the DHCP setting to "static" AND headless during the update :-)

[Fourdee]

@GrahamGIGA

Is this the same system, PSU and SD card as: https://github.com/Fourdee/DietPi/issues/2353?

If not, please can you list the above for this system also?

[GrahamGIGA]

No, this is a differemt system. Now working fine after the "fix" to the static IP and headless settings.

[Fourdee]

@GrahamGIGA

Unable to replicate this in our local testing.

I believe this is now resolved? I'll mark as closed. If problems persist, please reopen.
