After upgrade to 42.3 I lost my wifi my only means to the internet

Same old problem but I can’t use a snapshot to go back. My TPLink adapter does not see my network after upgrading to 42.3 I did the upgrade from 42.2 to 42.3 following the example of HTTP:// When I rebooted I had the same problem as in my last post Is there no way to prevent this from happening when I upgrade? This is disheartening. I backed up data before I did the upgrade. Can this help me get my settings back so I can go on-line? The backup file is named Archive_Local Folders_inbox_2015-12-19.tar.bz2 It is located in my Home folder. Thanks for any help. I feared this would happen but I cannot refuse to upgrade because of this problem.

Did I make the error following the advice of kamarada by deleting the TP link related repositories? Is this where I made my fatal error?

I got it straightened out by going back to my old rlt8187 adapter. I got connected and got my repositories back. Is this something that I will have to live with when I upgrade?

Does this mean that, you usually have another WiFi interface device for your system?
And, if so, what?

The Realtek rtl818x driver is part of the Linux kernel for quite a few years now. We need to know which WiFi interface device is “normally” used by your system.

Thank you for responding.

Yes, I have an older spare adapter a RTL8187. It is probably 8 years old or older? I do not normally have this one connected. However, the kernel seems to recognize it better. I also have the higher performing TP-link (Archer T4U) that supports the high performing 802.11ac wifi. This is the one that I use on a regular basis. At the end of the upgrade, the system went dead (stopped responding) and I rebooted. I waited about 5 minutes before I rebooted. Maybe if I had waited longer I would have been OK and the system would have latched on to it? What do you think?

Again, I thank you for your help.

If the device is supported by a kernel driver it should have been available during boot.

I also have the higher performing TP-link (Archer T4U) that supports the high performing 802.11ac wifi.

Can you provide the chipset details for this device?

As far as I can tell, it’s a RTL8812au

Bus 002 Device 002: ID 2357:010d

This chipset is supported by the rtl8812au driver, supplied by a third-party package eg✓&q=rtl8812au&search_devel=false&search_unsupported=false&baseproject=openSUSE%3ALeap%3A42.2

I am sorry for not being clear. I am now using the 8812au adapter. But it did not initiate by itself after the upgrade. I had to get online with the old 8187 to get it working. Could it be that it just takes a super long time to be recognized and that I was too impatient? Is that a possibility?

The 8812au adapter requires a driver that is available from a thrid-party repo, or built from source as you said you’d originally done. So after upgrading to openSUSE 42.3, you need to subscribe to the repo (see link post #9) and install ‘rtl8812au’ and ‘rtl8812au-kmp-default’ packages, or build again by hand as you did for your prior kernel.

So what you are telling me is that after an upgrade I will lose access to the internet with that adapter and I will have to use my old adapter to access the internet so that I can install the third party driver. (This is what I did). Why not integrate that third party software into Opensuse so I won’t have to go through this ****? Am I missing something here? Thank you for your help. I admit to being on the opensuse learning curve. It is just that the average computer user simply would find it hard to deal with these problems.

The driver is proprietary and openSUSE is only open source software. Note the name :wink:

You could download the RPM and run it from your machine. Then only need to download for the next OS version since it would have to be rebuilt for the next kernel

At least one package mentioned earlier has “License: GPL-2.0”. Do you imply that packager intentionally cheated and added OSS license to proprietary software?

  1. If you install openSUSE, you have to install the driver from this Repo, because the driver is build for the Kernel shipped with openSUSE Installation Media (also the OSS Repo):

  2. If you have installed the driver as shown in 1. (before updating your System, because the driver in 1. will not work) or you have made an Upgrade from an earlier openSUSE Version, you have to enable this Repo, because the driver in this Repo will build against the latest Kernel in the Update-OSS Repo.
    After that, only zypper up is required…

Thank you all for helping me understand a bit more about the Linux system. I am still on the learning curve. I have to admit that when I have every thing working the way it is suppose to, I love the Linux system. Nothing like beating Microsoft at its own game!! LOL. But if it were not for this forum I would be in deep do do. I hope it is always here for hacks like me!! LOL.
