Wifi on linux mint disconnects and vanishes are 30 secs off booting.

[Apemanonline]

I have 8 linux mint systems 4 of them use the same wifi usb dongle normally all i have to do is update to the latest kernel and its all systems go. But this unit ............ I tried rolling back the kernel to below. I tried swapping ports as some ports are controlled by the cpu and others by chipset swapping works until you reboot. I tried a different wifi dongle from a working system doesnt help other one works fine in the other system.

 

Mint 22.1 cinnamon 6.4.8 kernel 6.8.0-60-generic

 

i7 3770

 

16gig ddr3 (2*8)

 

128 gig sata ssd

 

So they another retired friend can get online and learn things.

 

Works fine on wired and everything tests out ok.

 

Just cant get the dam usb wifi and not vanish to stay connected.

 

Still got a lot to learn and im outa my depth here any help?

 

Update after finding and using 100000000 no idea wtf they terminal commands i finally got this

 

inxi -nn

 

realtek 802.11n Wlan adapter driver: rtl8xxxu type: usb

 

so we know its plugged in just disconnects and wont work. I checked its the same info on 3 off machines i was able to get friends to type that command in for me (YES THAT WAS REAL FUN TRUST ME)

I'm not sure what to make out of the above as, no offence, your post is a bit all over the place.

 

Let's start with the make and model of your USB dongle - if you could share this, it would be great.

 

Please also share the line containing the dongle from the output of the "lsusb" command. From your post we already know it's a Realtek chipset but that's not enough. The USB IDs should hopefully tell us a bit more about the exact device.

 

Finally, please also share the output of:

sudo dmesg | grep -E "rtl|realtek"

which will look at the kernel logs since the last boot and filter for messages containing "rtl" or "realtek" and might help us see any possible errors regarding Realtek devices.

 

From the symptoms, a few possible avenues are - driver/firmware issue, power management (e.g. USB port being powered down), or faulty dongle. Have you checked if the dongle works on another system? If it does, it could rule out the latter.

Found a post on another forum that suggested using a different set of realtek drivers so i used 

 

sudo add-apt-repository ppa:kelebek333/kablosuz

 

The used driver manager and selected the new driver so far so good. No idea if its safe to do this but the amount off commands i enter into this thing with no clue wtf they are LOL.

 

Many thanks Noleafclover. Looks like it solved but thanks again for trying.
