Latest Updates [Week of 5/4] causes wifi to disappear

General Help
1

On two different occasions I have attempted to update my 18.1 core version with the latest updates, but after installing and restarting my wifi no longer works.

When I attempts to list my networks nearby, nothing will show up. Looking at the logs, I do see something about a power profile unable to start, I don't have the exact messaging right now. I do have virtualBox installed on the machine, so I don't know if there might be a conflict with the network stack that comes in with virtualBox causing the Wi-Fi drivers to fail to load or run properly.

I'm really new to Linux, not afraid of tech, as I'm a software developer, but I have no idea where to start troubleshooting or how to make sure that I can do the update properly so that the latest security updates are in play, without killing my Wi-Fi every time.

I do use time shift, which is what allowed me to bring the computer back up. Each time I run in the older version I don't have issues; but I do remember the last update having a similar issue causing my Wi-Fi to disconnect and stop working entirely after about 30 to 45 minutes. One tutorial took me through turning off the power standby, and I followed that which resolve the issue. This might also be part of the issue but I'm not sure how to even check.

Any tips on where to go or how to begin troubleshooting. Remember I'm not afraid of the terminal, and I'm not afraid of potentially messing it up. This is a new venture for me and I'm excited to start using open source software and the power that Linux now brings to the world of computing. Especially for those of us who are tired of paying to be monitored.

Hi and welcome.

Based on the information you have given about booting in advanced mode and choosing an earlier kernel might be the issue. What I mean is, when new Linux kernels get released, sometimes hardware drivers become deprecated and don't work as they should. I would stick with the kernel that works with your wifi. @Aravisian has helped others in the past on how to prevent newer kernels from being installed and prevent upsetting your system.

Thanks for the quick reply! Yeah I've turned off automatic updating for the short-term. I just need to know how to make sure the kernel doesn't update I guess. I'll do a little investigation on my own as well, so maybe I can be a little proactive in learning this new world.

You can set the older kernel as default boot, so that your updates can run normally.

Unfortunately that didn't work. I see both, but the WiFi driver remains inoperable. When the system is back up I'll grab logs if I can.

Ok, looks like my issue might be with the fact that my laptop is using Realtec Wifi drivers.

   description: Wireless interface
   product: RTL8822BE 802.11a/b/g/n/ac WiFi adapter
   vendor: Realtek Semiconductor Co., Ltd.

I saw a suggestion to install a different driver. Any ideas if this is the correct path forward?

Yes, proceed with installing the RTW88 DKMS driver now, before applying the kernel update.

The search results confirm that installing a DKMS driver (like the one from lwfinger/rtw88 ) is the standard solution to prevent WiFi breakage after kernel updates on Zorin OS for your RTL8822BE chip.

Hola chicos si asi es olvide crear un tema similar a esto de echo en una actualizacion en vez de navegar a maxima velocidad iba a 300 mbps pero yo realmente tengo 10Gbps de velocidad pero por WIFI 7 BE6500 alcanso puros velocidades 2.2 Gbps en ciertas horas cuando la red est amas libre y si puso una controladora nueva pero no puso velocidad maxima asi que tuve que reinstalar todo y desacerme del driver de dicha actualizacion y le dije al sistema que a mi wifi no me lo toque mas ia que un ChatGPT mejor dicho KIMI AI en google y me ayudo a reinstalar todo al sitio y recupere digamos el control de mi zorin ..

Ok, I tried something different last night and everything is now working just fine. Basically, I went into the settings for the Software Updater and turned on the Sources repos. I applied all the updates and rebooted -- the wifi is up and stable, working perfectly like it was before.

Not entirely sure if it is 100% related, but might have just been the fix.

yo diria lo siguente mejor bloquear asi el actualizador no estropeara lo que tenias en wifi es como una medida de protecion es como decir al sistema entero "Oye eso ni se te ocurra actualizar , funcciona bien " el systema dice val vale perdon jajajaja y ya no actualiza mas tu red y se la salta esa protecion es buena preguntalo a KIMI te explique como acceder y hablar con el y puedes hacer con muchas programas algo similar .como siempre yo usoa a KIM como profesor de linux :smiley:
