So far as I can see, the RT3072 chipset in your dongle needs the RT2800USB driver, and it might not be there. If it is, you have to make sure any other Ralink drivers are blacklisted.

As supported wifi dongles are pretty cheap, you might think it is easier to bin the EDUP.

Hi R101:
My EDUP WIFI-key in pi3b & pi3b + is currently working properly.

But I don't understand why it happens all the time during boot-up:
A start job is running for sys-subsy-wlan1.device..
Whether you plug in EDUP WiFi or not, it will appear. And it will take nearly two minutes to turn it on. It bothers me.

Hi andre_chang,

...My EDUP WIFI-key in pi3b & pi3b + is currently working properly...

This is good news.
I notice that I made a typo in my previous post concerning the pacman -Sy linux-firmware error, the correct command is:

Code: Select all

rm /var/lib/pacman/db.lck

You should run this, but there is no need to install the upgrade for linux-firmware since your WiFi dongle is already working.

…A start job is running for sys-subsy-wlan1.device...

I don't think this is a problem.

...And it will take nearly two minutes to turn it on...

I will take a look at this and get back to you if it can be fixed.

Hi janui:
Rm/var/lib/pacman/db.lck< -- This command has been run.
Although my EDUP EP-MS1558 300M dongle is working properly, I still upgrade for linux-firmware. Success. Hope to solve the problem that A start job is running for sys-subsy-wlan 1. device.. But unfortunately.. I still have to wait 1 minute and 30 seconds during boot...

I'm trying to pick up the boot process for your reference. I hope you can help me find a solution. Thank you for your help.

Hi andre_chang,

...But unfortunately.. I still have to wait 1 minute and 30 seconds during boot...

Could you try something for me? In the directory '/etc/netctl' there is a file which has the same name as your (hidden) WiFi SSID. Could you edit this file using:

Code: Select all

nano <filename>

And add this line:

Code: Select all

Hidden=yes

Add it after the line starting with 'IP=' (Exit nano with <ctrl>o then <ctrl>x).
Then reboot.
Could you post the new connect time for WiFi.

Hi janui:
I've added it as directed by you, but there's still a screen waiting for 1 minute 30 seconds when I turn on.

This screen prompt needs to be waited for:
A start job is running for sys-subsy WLAN 1.device (1min 30s)
The display is "wlan1"
My current EDUP EP-MS1558 300M dongle shows WLAN 0<-
My
Look at my screenshot.

Hi andre_chang,
Looks like a wlan1 was defined as some point in the past, maybe by plugging in the WiFi dongle before the on board WiFi was disabled. The wlan1 device is now no longer available, but the job to start it is still starting up, this runs until it times out.
Try this command via SSH:

Code: Select all

netctl list

if wlan1 is shown in the output then use the following commands:

Code: Select all

netctl stop wlan1
netctl disable wlan1

Then reboot. Then use the following command:

Code: Select all

find /etc/netctl/* -maxdepth 0 -type f

If wlan1 is shown in the output then delete it with the command:

Code: Select all

rm /etc/netctl/wlan1

Hi janui:
It seems that wlan1 does not exist.

********************************************************
I spent 2-3 hours searching again: a start job is running for sys-subsy WLAN 1. device (1 minute 30s)...

Tools:
1. PI3B+
2. Brush in SD card for 20180903_runeaudio_rpiB2.img
3. Local Area Network Connected to the Internet
Only these three samples are not inserted into EDUP EP-MS1558 300M-wifi dog..

4. Turn on the power-on
5. SSH logs in to Rune keyin:
Chown root.root/srv/http/command/lyric.sh
Chown root.root/srv/http/command/artist_info.sh
Chmod 600/srv/http/command/lyric.sh
Chmod 600/srv/http/command/artist_info.sh

6. SSH key-in reboot
7. SSH login key-in:
Rm-f/var/www/command/mpd-watchdog
Cd/srv/http/
Git config user.email "any@body.com"
Git config user.name "anybody"
Git stash
Git add.
Git pull
Git stash
CD /home
/ srv/http/command/rune_shutdown
Reboot

8. Open the browser http://runeaudio/dev/on dev-mode
9. gitpull -- Displays "Already up to date"
Step 1-9 The switch function is normal.... No a start job is running for sys-subsy WLAN 1. device (1min 30s)

10. Disable onboard WiFi Bluetooth:
SSH logoin:
Nano/boot/config.txt
join
Dtoverlay = pi3-disable-wifi
Dtoverlay = pi3-disable-bt
Save - Exit nano...
11. Reboot: a start job is running for sys-subsy WLAN 1. device (1min 30s) problem.

12. SSH logoin:
Nano/boot/config.txt
# dtoverlay = pi3-disable-wifi
# dtoverlay = pi3-disable-bt
Save - Exit nano...
13. Reboot... a start job is running for sys-subsy WLAN 1. device (1min 30s) This problem... Disappears

Obviously (1 minute 30s) this problem has already arisen when off-board WiFi and Bluetooth are turned off.
You can try to replicate the problem by testing it on your device in my way.

PS I tried another way to shield board WiFi and bluetooth:

Step-a: nano/etc/modprobe.d/disable_rpi3_wifi_bt.conf
##wifi
# blacklist brcmfmac
# blacklist brcmutil
##bt
# blacklist btbcm
# blacklist hci_uart
*********** becomes ************
##wifi
Blacklist brcmfmac
Blacklist brcmutil
##bt
# blacklist btbcm
# blacklist hci_uart

Step b: Save Exit - Restart

(1 min 30s) The problem still arises.

Hi andre_chang,
Please post the output of:

Code: Select all

find / -name *wlan1.service

And

Code: Select all

dir -l /etc/systemd/system/multi-user.target.wants/
