Wifi card not recognized, please help..

[moldypastaman]

My wifi card, Herald BE Wifi 7 Max, is completely hidden in my system. I tried the lspci grep command and it didn't even show my card, it only showed my ethernet adapter. Please help.

Welcome to KFN.

How did you install Kubuntu? What version? Without Wifi, you would have had to have a wired Ethernet connection. Is that the case?

I used usb tethering from my phone to install it. I am using kubuntu 26.04 lts.

Which specific command?

Try using lspci without using grep, it isn't necessary for basic info, and your exact command for the grep side might just be incorrect or doesn't filter for the correct wording used.


That device is a Qualcomm NCM865, and it should be detected, unless it isn't seated correctly or otherwise has been disabled in the BIOS or something. Even if it did not work, it would show up in lspci.
Qualcomm wifi is often a big pita, but I don't see any strong info on it related to *buntu, but enough from other distros in the past couple of years that it does seem to work, with possible issues

Which specific command?

I used the lspci -nn | grep -i network command, which only showed a Broadcom ethernet controller.

I used the lspci -nn | grep -i network command, which only showed a Broadcom Ethernet controller.

And for me, it is the exact opposite; I see my wifi card but not the Ethernet. It depends on how the device labels itself, and maybe this card does not use the word "network" for this at all.

If you are worried about the possibly long output from running lspci -nn without any text filters, try subbing different text strings in place of "network". Say "wi-fi" or just "wi"

But even running it without the grep part, it should be very obvious which line refers to your Wi-Fi card.

Always remember too, Linux is case sensitive. network isn't the same as Network. When using grep it is 'better' IMO, to be as unspecific as possible while still being relevant to what you are looking for. I would use lspci -nn | grep work (which I just did on my laptop) and it produced a single match:

grep -i makes is case-insesnitive. On my small PC, "net" shopws both, network shows one.

I have fixed the problem. I tried all listed commands and they showed nothing, so I determined it was a hardware issue and reset my network controller. Thank you for the help.

that happens ...sometimes the simplest little things is the cause of headaches
