No wifi on hp stream 11 after kubuntu installation

[daniel.knight97]

I installed kubuntu on a hp stream 11 laptop. I open the driver manager and the proprietary driver comes up which is a broadcom device. I can set the driver on and the manager and the computers wifi does not work. The only connection that i can make is a wired connection from my cell phone due to this computer not having a ethernet port.

I have not had to deal with a broadcom chip in ages, butr have you rebooted after enabling the driver?

If it still is not working, please post the output of this command so we can see device info:

I'm also really new to the forum and still learning how to use.

Oh, yeah, what version of Kubuntu?

[jglen490]

If you can connect to the internet via your phone, then you might try this

sudo apt-get install wireless-bcm43142-dkms

.

No guarantees, and I don't have that wifi chip, and Broadcom has been traditionally difficult. But it might work ...

[daniel.knight97]

It is kubuntu 19.04 i just downloaded it today claydoh

[daniel.knight97]

I tried to see what it would do. it couldn't locate the package.

[claydoh]

there are now two different ones now, with different names. Each one takes a different version of broadcom's driver code and build it for your specific kernel, and automatically rebuilds it whenever there is a kernel update. What I do not know is which one the driver manager has installed for you.

one is called bcmwl-kernel-source and the other is broadcom-sta-dkms

I think the first one is the likely one used, so you can look for it in Muon package manager, or from a terminal:

apt policy bcmwl-kernel-source

If it shows as installed, you will want to purge it, which you can do using Muon, else:

sudo apt purge bcmwl-kernel-source

Reboot, and try installing the other, using Muon, else:

sudo apt install broadcom-sta-dkms

and reboot

No idea if it will work or not, and there are other issues that could be in play. There are tons of reports about this particular card, and it seems to be hit or miss as to what works for each individual chip.

Also, it may help to disable secure boot in your bios before you try anything else

[daniel.knight97]

Thank you for all your help I disabled secure boot in the BIOS. i went to muon and installed both and rebooted the system the wifi is working properly at this time. thanks again for all the help i am new to the operating system. hopefully ill learn it quick and enjoy it.
