HP Pavilion Dv5 won't connect to Wi-Fi

So, i've got this laptop from a friend.

it was running perfectly on Windows 7 but since it is a relatively old system, i figured it was better to install Zorin OS 15.3.

The installation process went smoothly except for one part. it wouldn't connect to any wifi network even though it was recognizing them. Since it was the installation process, i hooked an ethernet cable and it worked so the installation process could proceed.

At the desktop, the same thing happens - it is able to recognize all nearby networks, but it won't connect to any of them. I've even tried creating a wifi hotspot with an android phone, but no success at all. When i input the password, it tries to connect for a few seconds and then give up, outputting no errors.

I've read other posts here, but it really didn't helped much because the fixes were pretty hardware specific.

I saw people asking for the output from these command lines:

lspci -nn | grep 0280
lsusb
sudo lshw -c network
sudo rfkill list all

that was the result:

In terminal, can you run

sudo nmcli networking off

Followed with turning it back on:

sudo nmcli networking on

Then open your network connections from Settings > Wifi and try to connect.

Just tried that, no results :slightly_frowning_face:

It just keeps trying to connect and then gives up.

Ok, maybe the kernel is not assigning the module:
In terminal:

echo "options rt2800pci nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf

sudo modprobe -rfv rt2800pci

sudo modprobe -v rt2800pci

Log out and in or reboot and test...

Hey thanks for the quick response :smiley:

Anyways, i've tried turning the laptop on and now it won't even start the boot process, probably there's something wrong in its MoBo. So the fix would have to wait :sweat_smile:

Thanks anyways :smiley:

Hopefully it is not something serious.

unfortunately it was quite serious haha - i've dissasembled it with quite difficulty, it feels like HP notebooks designs were meant to be puzzles :sweat_smile:

but i tried cleaning everything - and there was a lot of broken plastic and dirt inside of it (maybe that was what wrecked the mobo). I also wasted some thermal paste on it, hoping it would work after the cleaning, and that i wouldn't have to open that ever again - but it changed nothing, the notebook still turns on, but won't even start the bios.

at least i was able to harvest some cool components: 2 DDR3L RAM sticks, the Ralink wi-fi/bluetooth module, a 300gb HDD, the screen and a DVD drive

Anyways, thank you for your help! I guess this thread could be closed.
