1 year ago Hi @DC072012
I really need you to read and follow the pinned issue called Problem Reporting Guidelines.
Also, ifconfig has been depreciated and is no longer supported. Please use iw and ip instead.

1 year ago Sorry - I didn't see the pinned post. I am now following pinned post to the best of my ability - please advise if I am still doing something wrong. I appended my original post to the end of this. Thank you.
Here is info in order requested, some of which is redundant with my first post I think.
NOTE: I tried ipconfig and got this: ipconfig -bash: ipconfig: command not found It does not work on my Pi

There is no ipconfig as far as I know. ip and iw are what I am talking about.
Example:
$ ip link $ iw dev
Those replace iwconfig.
I'm seeing a lot of problems with the RasPiOS lately. It is not obvious what is going on here. I'll look at doing some testing here lately this week. Tell me exactly which iso of the RasPiOS you are using and tell me which RasPi is booting it?
You could try:
$ sudo apt update $ sudo apt upgrade $ sudo reboot in the driver directory: $ sudo ./remove-driver.sh $ sudo reboot sudo ./install-driver.sh

Okay, there we go. That is the wifi interface for your usb wifi adapter. All looks well.
I also see that your internal wifi is connected to an AP on channel 9. Your wifi router/AP should really only be set to 1, 6, or 11 for the 2.4 GH band. You may want to disconnect that connection. In the README I have instructions for how to get rid of wifi connections on a RasPi. Once that connection is gone, try connecting with to a 5 GHz channel as that would have to be from the adapter.
FYI: I have a RasPi3B as well. I use the following version of RasPiOS with good success:
https://www.raspberrypi.com/software/operating-systems/
Raspberry Pi OS (64-bit) Raspberry Pi OS with desktop
Also, FYI: The Main Menu for this site is:
https://github.com/morrownr/USB-WiFi
It has a lot of info.

1 year ago Thanks again. I did follow the remove / reinstall process. I also changed the wifi channel on my router to channel 11.
USB adapter is seen but still is not connecting (see new ip and iw below)
I'll look at your website also and see if there is anything I can pick up there.
Updating to a new operating system is problematic unless it can be done remotely in headless operation. The Pi is installed in a remote location and has a bunch of wires attached to the device it is monitoring.
If I try to connect with the 5 ghz channel and it doesn't work then I'm in a big problem and would have to drive to the remote site and hard reboot the Pi. Doesn't that Pi also support 5GHZ without the dongle?

I understand. So that I can more fully understand, tell what your goal is? Is it to make wifi more reliable or to increase range?
Doesn't that Pi also support 5GHZ without the dongle?
Let me ask my RasPi3B... it said, nope, I can only do 2.4 GHz band. I think dual band started with the RasPi3B+ but I would have to check on that.
The status as I see it right now is that the driver here has done its job. You have a wifi interface for the usb adapter. If it were me, I would probably leave things along until I am going to make a trip to that location anyway. Then I would put the correct line in the config.txt to shut down the internal wifi and then I would reboot and as you are using wpa_supplicant to connect, the new adapter should use your connection information and connect.

1 year ago Thank you again. I do have the RasPi3B+.
My goal is to increase the signal strength to get it more reliable. Using the onboard wifi the signal is around -70db. I'm expecting the USB would come in around -40 which would be less sensitive to other interference.
Next time I'm going to be near the remote site I will test your idea of turning off the internal wifi and see if it will cause the USB to start working.
In the meantime if you do any further testing or have more suggestions please let me know.

1 year ago I was able to get to the remote site. I connected to the onboard wifi and added the "dtoverlay=disable-wifi" to the /boot/config.txt file. Power cycled the Pi, and the USB would not connect to wifi. Tried this repeatedly.
I also unplugged the wifi adapter, tried a different USB port, and power cycled the Pi. Still the USB wifi would not connect.
Then watching my router monitor the USB connected briefly, then was gone again and never reconnected.
I couldn't connect to the Pi without going through a bunch of hoops since the onboard wifi was turned off. It was 30 degrees and raining so I swapped out the SD card with a backup so the Pi is working again on the onboard wifi. I have a cron job to restart the onboard wifi when it goes down and that has run 3 times today. So I still need to solve this.
If you have an opportunity to do some testing with my setup please let me know what you find.
Thanks for your help.
I searched all of the issues and don't see how to fix this. The USB dongle is wlan1 in the following. Any help will be greatly appreciated.
