USB wifi adaptor for linux

[norbra]

I have installed Mint alongside windows,all went well but when I boot from mint, no wifi.

Help with finding a suitable adaptor would be appreciated as my current one worked perfectly in windows.

Thanks for any suggestions.

Is it a dual band adapter realtek chipset (can check this in windows device manager and which driver version it is)? if so linux mint kernel 5.15 does not contain realtek chipset dual band wifi kernel drivers and the drivers need to be installed or update mint with a later kernel (min kernel 6.2 version)which contains the realtek dual band drivers (I think the latest kernel update for Mint is version 6.6)

 

You can use a single realtek 2.4G usb adapter or a lan connection to connect the network and then either install the realtek dual band out of kernel drivers or update the kernel (min 6.2) and then you can use your dual band wifi adapter.

 

Wifi adapters with Mediatek chipsets single and dual band wifi are supported quite well in linux.

 

This github site has lots of info on the adapters chipsets for linux.

To update the linux kernel this explains quite easy

I have kernal 5.4.

Please be gentle as I haven't looked at Unix for 30 years,did an HP operators course.

My current adaptor is. Realtek 8811CU

OK kernel is old, the wifi chipset 8811CU is supported in the kernel now (after 6.2)

 

Need to connect to the internet, do you have access to a 2.4g adapter or a lan connection?

 

I think the easiest is just update the kernel from software update kernels in mint.

Try using the following from the command line as a sudo user.  The mint installation may not have installed the driver for your type of laptop.

 

sudo apt install bcmwl-kernel-source

 

Good luck.

Open Linux and update your software. I also have Mint and no problem with WiFi. Once updated try your WiFi again

Many failures connecting to server.

Have found an old DLink adaptor which works fine but has wifi signal issues,poor weak connection. I have just tried to install Ubuntu kernel Sudo add-apt-repository PPA:canonical-kernel-team/PPA with no luck

That is for broadcom chipsets. The wifi adapter 8811CU is a realtek chipset.

You have linux mint, need to install mint kernels.

 

Available from update manager in linux mint.

 

-Need an internet connection

-Click start and open update manager in mint

-Go to ''view'' tab at top

-Select the kernels option

-Chose the kernel (6.5 or 6.6) in the left column and click update.

 

Let it run its course install and then reboot.

 

In a terminal type uname -r and it should show you what kernel is being used.

All good, once installed plug in your usb wifi 8811cu and reboot that should be working in dual (2.4 and 5G) band then.

Thanks for your time and great guidance,now that I have a stable network connection as an 86 year old I have many new challenges to master mint.

Wife will be happy router is out of sight again
