dietpi-config error

Troubleshooting
#1

Using NanoPi NEO with v140 dietpi

Trying to set up static IP for wireless through dietpi-config.

Seems to be a few issues. The static IP was not applied on first setting. After reboot it got applied.

I tried turning off IPv6 as I don’t need it. Dietpi-config says it is turned off, but netdata monitor shows there is IPv6 activity (errors) and it hasn’t been disabled.

During trying to set IP things up, this error would flash across the screen before returning to the menu.
/DietPi/dietpi/dietpi-config: line 2292: ((: < 0 : syntax error: operand expected (error token is "< 0 ")

#2

One other observation on networking on NanoPi.

The ethernet lights (green and yellow on connector) stay lit regardless of whether anything is connected.

With rpi these are off unless there is a live ethernet connection.

Hi Gordon,

Thanks for the report, i’ll take a look: https://github.com/Fourdee/DietPi/issues/681

In regards to the LED lights. I’ll pass this over to ARMbian as its most likely down to the dtb/fex that needs modifying.

#4

Hi Gordon,

I believe the IPv6 issue is a bug in NetData. IPv6 is disabled at system level, yet it pulls in invalid stats. i’ve created a ticket for NetData devs:
https://github.com/firehol/netdata/issues/1510

As for the:

/DietPi/dietpi/dietpi-config: line 2292: ((: < 0 : syntax error: operand expected (error token is "< 0 ")

Looks like its failing to pull in the Wifi Signal strength stats:

WIFI_SIGNALSTRENGTH=$(iwconfig wlan0 | grep -m1 'Signal level=' | awk '{ print $4 }' | sed 's/level=//g' | cut -f1 -d "/")

Could you please run the following command and paste results, should help us debug this:

iwconfig wlan0
#5

A lot has happened since I posted.
I downloaded a fresh copy V140 for NanoPi NEO and put it on the SD card.

Attached ethernet cable and usb power. Wifi dongle plugged in.

Booted and it went through the update and reboot.

Went through startup screens and selected dieti-config from menu.

In Network Options Adapters
Ethernet was available/Enabled and Connected
Wifi was available/ disabled and Disconnected

Clicked on Wifi and it said that it had to enable.
Automatic download of iproute and netplug **** IF you don’t have an internet connection how would you get these?? ****

[Info] Please wait, enabling WiFi Modules…
[Ok] wifi enable | Completed

In dietpi-config

turned of IPv6

reboot

ssh in - back in setup menu :cry:

Hoping that if I click install (with no software selected that I won’t get the menu system again)

It went through a whole bunch of stuff (although I didn’t select anything!) then it rebooted on me.

wireless still connected

IPv6 doesn’t show up. Good.
So, after all that, I think that I’ve got to the place that I want to be with ethernet and wifi

Hi Gordon,

Thanks for the report and feedback. I’ll go through those and see if we can make improvements.

You can pre-define WiFi options in dietpi.txt, after writing the image and before powering on. This would save you having to do lengthy process you posted above.

  • Write DietPi Image to SD
  • Make the changes in /boot/dietpi.txt:
Wifi_Enabled=1

#Enter your Wifi details below, if applicable (Case Sensitive).
Wifi_SSID=changeme
Wifi_KEY=changeme
  • Plug in WiFi dongle (no need for eth) and power on.

Wifi stopped working. This is the second time it has happened. I don’t know when as I wasn’t watching it. NanoPi was idle with the following running (no ssh or top):

When I got up this morning the wifi had become disassociated again with the access point.

dmesg (I don’t know if this coincided with the wifi dongle going down)
[ 212.086569] ieee80211 phy0: rt2800usb_txdone: Warning - Data pending for entry 1 in queue 2

This time there is no dmesg so I guess that was a red herring.

The wifi dongle is a WiPi

Gordon Williams

Edit:
I’ve tested with another wifi dongle and it works OK :slight_smile: No disassociation after 12 hrs of running.
Bus 004 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
So it looks like it is only a problem with the wipi dongle.
