Wifi client does not reconnect automatically

[nextcloudfan]

Hi,

I have eth0, wlan0 which connects to the internet and wlan1 which is the hotspot.

After a shutdoen or a reboot, the only way to access the RaspAP Gui is to use a cable connection on eth0. So you allways need a PC or Laptop.

No connection to the already setup Hotspot possible at this stage.
I have to enter the Gui via cable connection, go to Wifi client, connect to a network, even if it is already know and saved, there is no automatic reconnection. After reconnectiong in Wifi client, the Hotspot Wifi Network is available and can be accessed by clients.

Any ways of auto reconnecting to a know network in wifi client, or at least a possibility to enter the Hotspot network?
There are situations, where no PC/ Laptop is available and then there is no way to use RaspAp

Hi, This is not working for v3.4.5

When running the command: (Note: I have swapped wlan0 & wlan1);

sudo /sbin/wpa_supplicant -B -Dnl80211 -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan1

I get the following result:

Successfully initialized wpa_supplicant
nl80211: kernel reports: Match already configured
[ snip ]
ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/wlan1' manually if it is not used anymore
Failed to initialize control interface 'DIR=/var/run/wpa_supplicant GROUP=netdev'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

wlan1: CTRL-EVENT-DSCP-POLICY clear_all
wlan1: CTRL-EVENT-DSCP-POLICY clear_all
nl80211: deinit ifname=wlan1 disabled_11b_rates=0

However, if I go to the "Wifi Client" web page, it automatically does a Scan, which populates list_networks, visible by:

sudo wpa_cli -i wlan1 list_networks

& can then use:

sudo wpa_cli -i wlan1 reconfigure
sudo wpa_cli -i wlan1 select_network 1

and it will reconnect.

Question, what can I do to manually trigger the "Scan" on the Wifi Clients page in a Crontab script which includes the last 2 statements?

Hello everyone,

I also struggled for a while to establish an automatic reconnection after a reboot (or after losing the Wi-Fi signal) to a known Wi-Fi network. For me, the following solution worked:

(Note: WLAN0: Client Wi-Fi, WLAN1: Connection to the external AP)

• sudo ln -s /etc/wpa_supplicant/wpa_supplicant.conf@wlan1 /etc/wpa_supplicant/wpa_supplicant.conf
• sudo systemctl enable wpa_supplicant@wlan1.service
• sudo systemctl start wpa_supplicant@wlan1.service

RaspAP writes the known Wi-Fi networks to the file /etc/wpa_supplicant/wpa_supplicant.conf. The custom wpa_supplicant process for WLAN1 accesses the same file through the symbolic link.
This has been working without issues for me for some time.

Cheers - Michael

Thanks Michael,

I think you meant to write:

• sudo ln -s /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant.conf@wlan1
• sudo systemctl enable wpa_supplicant@wlan1.service
• sudo systemctl start wpa_supplicant@wlan1.service

However when I did this, it didn't work, so I ran:

• sudo systemctl status wpa_supplicant@wlan1.service

as part of the "Fail" message it noted:
wpa_supplicant[916]: Failed to open config file '/etc/wpa_supplicant/wpa_supplicant-wlan1.conf', error: No such file or directory

I ran:

• sudo mv wpa_supplicant.conf@wlan1 wpa_supplicant-wlan1.conf

And it Worked!!!

So for others running V3.4.5

• sudo ln -s /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant-wlan1.conf
• sudo systemctl enable wpa_supplicant@wlan1.service
• sudo systemctl start wpa_supplicant@wlan1.service

Works a charm! thanks for your help!
