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. https://github.com/morrownr/USB-WiFi/blob/main/home/USB_WiFi_Chipsets.md Edited January 6 by freeworld 1 1 Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

The mint installation may not have installed the driver for your type of laptop. sudo apt install bcmwl-kernel-source Good luck. Link to comment Share on other sites More sharing options...

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 Edited January 6 by norbra Link to comment Share on other sites More sharing options...

The wifi adapter 8811CU is a realtek chipset. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
