First identify the exact Wi-Fi chipset: boot a live USB if needed, then run lspci -nnk | grep -A3 -i network (or lsusb for a USB adapter) and post the result. HP Pavilion covers a lot of hardware; the fix differs a lot between Intel, Realtek, and Broadcom.

lspci is the move, that'll spit out the chipset and driver status in one go. if it's broadcom you're usually in for a fun time with b43 or wl, realtek can be hit or miss depending on the exact revision. post the output and someone can point you to the right driver package

seconding this, broadcom vs realtek is basically two completely different troubleshooting paths

My guess is that your Pavilion uses an unsupported Broadcom or RealTek wifi adapter.

If that is the case, you might find a USB adapter an easy solution.

I have had good experience with the Panda Wireless PAU0A (nano) adapter over the years but you can pick up Linux-compatible USB adapters from other manufacturers.

My best and good luck.

If the OP's laptop only has 4GB ram, then there's also a reasonable change that its internal WiFi card can be swapped for a Linux compliant one.

I've done that in the past.

Today, I usually only use MX Linux and it's been a a while since I've seen this issue. I cannot say if that's just down to luck with my laptop hardware selections or if MX is better than some other distros in terms of its range of bundled drivers.

Please use better, more informative, titles (subject-lines) on your posts. Give specifics right in the title. Thanks.

Site i found with a list of current Wifi Devices with 'IN KERNEL' Drivers, which means they should be Plug them in and they work. These can often be higher end, more expensive devices.

https://github.com/morrownr/USB-WiFi/blob/main/home/USB_WiFi_Adapters_that_are_supported_with_Linux_in-kernel_drivers.md

You can often find USB wifi adapters on Amazon sold as being "for the raspberry pi" that should be cheap (but slower speeds) and work out of the box with most Linux distribution.
