[frankdugan3]

Creating a bug report/issue:

Required Information:

• DietPi version | 6.16
• Distro version | stretch
• Kernel version | Linux DietPi 3.16.57+ #1 SMP PREEMPT Sun Aug 19 15:27:56 CEST 2018 aarch64 GNU/Linux
• SBC device | Odroid C2 (aarch64)

Additional Information (if applicable):

• Locale for WiFi (and everything else) is US (english)
• Latest updates and firmware applied

Steps to reproduce:

1. Enable WiFi, add SSID configurations, and eneable autoreconnect

Expected behaviour:

• It should be able to connect to the saved SSID configurations

Actual behaviour:

• No connection

Extra details:

• WiFi was successfully connected until turning on autoreconnect
• systemctl status dietpi-wifi-monitor reports the following:

@frankdugan3
Thanks for your report.

Hui took a while to even find this service in the code, as I never use WiFi with DietPi 😄.

#!/bin/bash
{
URL_PING="$WIFI_GATEWAY"
ADAPTER="wlan$WIFI_DEV_INDEX"
TICKRATE=10
while true
do
G_DIETPI-NOTIFY 2 "Checking connnection for: \$ADAPTER"
ping -I \$ADAPTER -c 1 \$URL_PING
if (( \$? != 0 )); then
G_DIETPI-NOTIFY 2 "Detected connection loss: \$ADAPTER. Reconnecting"
ifdown "\$ADAPTER"
sleep 1
ifup "\$ADAPTER"
G_DIETPI-NOTIFY 0 'Completed'
else
G_DIETPI-NOTIFY 0 "Connection \$ADAPTER"
fi
sleep \$TICKRATE
done

/var/lib/dietpi/dietpi-wifi-monitor.sh: line 16: G_DIETPI-NOTIFY: command not found

As we do not source DietPi-Globals, we cannot use G_DIETPI-NOTIFY here. Error our side. Either we need to source globals or use simple echo. As output should just go to journal, I would just do echo, also to reduce init time and RAM usage of the service.

Also currently it looks quite spammy, producing output on every tick. I would just create output, if connection was actually lost and after successful reconnection.
@Fourdee
What do you think?

So but the errors should no break the script. Also your status output shows it is active and running.

Other topic when checking the code:
https://github.com/Fourdee/DietPi/blob/testing/dietpi/dietpi-config#L3451

• Shouldn't this be $WIFI_DEV_INDEX here?

https://github.com/Fourdee/DietPi/blob/testing/dietpi/dietpi-config#L2434

• Network_Restart() should include stop/start the wifi monitor service, so it does not interfere.
• Perhaps best is to stop the service on every network adapter access and start it again when closing the menu? Also assure that service is recreated every time, WiFi adapter settings are changed, in case gateway and/or adapter has changed.

But besides that I do not find a reason WiFi should break and have no DietPi with WiFi device here to test. I hope Fourdee finds time to check.

[frankdugan3]

@MichaIng Not sure where it breaks, but in the end something in the re-connection script ends up dropping the connection. ip link reports wlan0 as down, and I can't ping anything outside localhost.

[MichaIng]

@frankdugan3
Strange, it should only drop WiFi interface, if it could not ping the gateway. Then it should bring up the same interface. So if $ADAPTER should somehow be wrong, it should not affect the right interface.

But if $WIFI_GATEWAY was wrong, it would be in a connection loop, perhaps breaking after some time.

Can you please do the following:

• Disable WiFi monitor, and make WiFi work.
• Get gateway via: ip r | grep -m1 'default' | awk '{ print $3 }'
• Ping that gateway: ping -I wlan0 -c 1 "$(ip r | grep -m1 'default' | awk '{ print $3 }')"
• Do you use DHCP or static IP? In case of static IP? In this case try to ping this static IP that you configured: cat -n /tmp/net_interfaces | grep 'gateway ' | sed -n 2p | awk '{print $3}'

[frankdugan3]

OK, here's the full log from the time of login until getting a successful connection. It's long, so I'll comment up here.

I'm using DHCP. The reason my previous log shows connection is because I had it running for a long time before I checked the logs, and it apparently connected eventually.

When I have autoreconnect off, the WiFi connects immediately both on changing the settings via dietpi-config and on boot.

The more I dig, the behavior is very strange. It becomes a very long connection process with a lot of false starts and stops when the reconnect script is starting the WiFi connection. It also times out WiFi during boot. Also, if I manually run ifdown wlan0 and ifup wlan0, the behaves the same way as the reconnect script. Perhaps this comes down to my particular WiFi module (Edimax EW-7811Un), but something is different about connecting during boot or dietpi-config and simply running ifup.

If I wait long enough, it does seem to randomly connect successfully. The issue is that it's so flaky it randomly drops the connection, and then randomly picks it back up after many false starts.

line 20: G_DIETPI-NOTIFY: command not found

Yep, needs globals loaded in.

If I wait long enough, it does seem to randomly connect successfully. The issue is that it's so flaky it randomly drops the connection, and then randomly picks it back up after many false starts.

This appears to be working as intended? If no ping result, the service will drop and restart the WiFi adapter.
Its then down to the adapter to achieve a stable connection, which it has 10 seconds to achieve before next check.

Looks more like a slow DHCP + possible signal strength issue.
Try using a static IP, under flaky connections it removes the need for DHCP lease/ack.

Also, whats the signal strength (dietpi-config)?

I'll setup my C2 with same adapter and run tests.

[frankdugan3]

@Fourdee The signal should be pretty strong given that it's 3 ft away from the AP. I haven't had issues with slow DHCP with any other devices, and there's only a few things connecting to the AP. The same image is also being testing in a completely different location with a different brand of AP with another C2 and WiFi module (same model), and it's behaving exactly the same way. An older image with an older version of DietPi does not have this issue on the same hardware and network.

I'm starting to think this is coming down to a WiFi driver issue. @Fourdee are you using the same WiFi adapter as me (Edimax EW-7811Un)?

[Fourdee]

@frankdugan3

Yep, testing now.

🈯️ Confirmed, dmesg full of constant reconnects.

Actually, the above is due to connecting on a hotspot, where the gateway scraped from active (eth0) is not available for ping on wlan.

[Fourdee]

So the issue appears to be, when both eth and wlan are enabled/active, with the wifi connection script, and, connections are on different subnetworks:

• Ping from wlan fails:

root@DietPi:~# ping -I wlan0 -c 1 google.com

Causing the re-connection script to constantly reconnect.

---

Also fails to ping the gateway of wlan0, when on different subnetworks:

root@DietPi:~# ip route show 0.0.0.0/0 dev wlan0 | awk '{print $3}'
192.168.43.1
root@DietPi:~# ping -I wlan0 -c 1 192.168.43.1
PING 192.168.43.1 (192.168.43.1) from 192.168.43.65 wlan0: 56(84) bytes of data.

@frankdugan3

• Are both eth and wlan connections on the same networks? eg: 192.168.0.*
• Do the problems still occur when eth is disabled and system rebooted?

[frankdugan3]

@Fourdee They are on the same networks. By disabled, do you mean configuration or just pull the plug? It definitely has the issue when eth is unplugged.
