Hi, I downloaded this driver

https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
and separately compiled it for each Xenial64 and Bionic64. The Xenial works like a champ.

The Bionic does work but it throws a error when trying to associate with the router via wpa_supplicant.

Even though it does this, I can still DHCP successfully.

And I get a usable internet connection.

Because this is happening, I have to manually go through network setup each boot. Not Fun! Sad

So what am I doing wrong here?

What logs will you need me to post?

Thanks in advance!

Have you done Bionicpup64 8.0 updates? Quickpet>Info>Bionicpup updates.
This will bring Bionicpup64 8.0 up to date with all the bug fixes at the time you do this.

What WPA setting are you using?

Is this a USB wifi device?
If yes.
Tried it plugged into a USB 2 port or different USB 3?

I know, you may have it plugged into the port that works with Xenialpup, but this is troubleshooting.
Xenialpup and Bionicpup are different OS.

OK, Found a workaround.

TL;DR: Use Frisbee network setup if you compile a wifi driver.

Detailed answer:

Well after trying to figure how to get the driver to work with network wizard which has been my favorite net setup utility since it's inception as I have found it to be quite versatile at anything I would throw at it over the years.

I dug into the source code and discovered that the Bionic64 version testInterface() function starting at line 1011 of /user/local/network-wizard/net-setup.sh has some substantial differences from the zenial64 version. Specifically, I noticed the removal of "ifplugstatus" in the test function. I am thinking those differences are what is tripping up the utility from working correctly. BTW, RTL8821cu compiled driver also failed on the utility.

Not wanting to hack a custom version for this laptop as my bash/shell scripting skills are not well developed. I decided to try the other two options: Simple Network Setup (SNS) and Frisbee.

Well SNS *did* setup correctly without errors but would not activate correctly after a reboot.

Frisbee did. Yay!

So I am considering this solved (Well, sort of solved) and hoping the Devs will look into making the network-wizard testInterface() function more robust in the future as it really is my favorite net setup utility.

Warm Regards
Overdrive

P.S. Thank you bigpup for your prompt and thoughtful response! I *did* try them all before digging into the source code.

Now you know why there are 3 network connection programs in most Puppies.
Never have been able to get one to work 100% for every possible computer/hardware.

I use Network Wizard for the reasons you stated.
So, far it has worked for me.

If you think you may have found a bug in the latest version of Network Wizard.
We the users help and work on Puppy code.
Start a topic offering your fix.
Others will test and offer help.

Could also post a pull request at Woof-CE
