[Solved]HP Laptop Wifi-Broadcom and Realtek not working.

[wnmc]

Hello, I am having problems getting my wifi working. I am running Linux Mint 17.3 Cinnamon 64 bit.
Network: Card-1: Broadcom BCM4318 [AirForce 54g] 802.11a/b/g PCI Express Transceiver
driver: wl
IF: N/A state: N/A mac: N/A
I have been reading through posts in this section and cannot find a fix.
I also have a usb wireless adapter.
Card-3: Realtek RTL8192CU 802.11n WLAN Adapter driver: rtl8192cu
IF: wlan0 state: N/A mac: N/A
I don't know which one is more compatible if compatible at all. Any help would be greatly appreciated.

Thank You wnmc

Welcome at the LinuxMint forum Wnmc,

Difficulties with wife are common on this forum. 3 (easy to difficult) solutions.

1. Buy a LinuxMint compatible wifi adapter for about 20 dollars. Check out this forum post for good tips.

2. If it is not too much of a hassle, try installing LM18.3 or LM19. LM17 isnt supported for updates anymore pretty soon, so you'll have to update to another Linux version anyway. This could be the moment. Maybe a newer Linux version will solve your problems automatically with a bit of luck.

3. Try tweaking and finding difficult ways to make your wifi work anyway. I cant help you with that personally, but maybe some more experienced forummember can. It can be very timeconsuming though.

Ok, I will upgrade to 19.

Thank you

For the internal wifi do

Code: Select all

sudo apt-get purge bcmwl-kernel-source && sudo apt-get install firmware-b43-installer

Reboot

JeremyB, I have noticed you help a lot of people on this forum and I want to say thank you for that. I have just installed Linux Mint 19 and am currently using my usb wifi adapter and it seems to be working just fine. I don't even see the light on for my laptops wifi, I am ok with that as long as the usb adapter is working. I noticed when I booted for the first time in LM 19 it said the Cinnamon desktop has crashed, so I tried to restart it and it failed so I went to the fallback mode. I will post in the appropriate topic for help with cinnamon. I am going to look at some updates first and see if that fixes it.

Thank You

If you have issues with that USB adapter in LM 19 check

Code: Select all

lsmod | grep rtl

If you see rtl8192cu and rtl8xxxu in the results do

Code: Select all

echo "blacklist rtl8192cu" | sudo tee /etc/modprobe.d/rtl8192cu.conf

Reboot

The solution for the internal adapter is the same

Ok, thank you very much.

JeremyB, My usb adapter was working fine and I got confused and ran that command thinking it was for my laptops card:

echo "blacklist rtl8192cu" | sudo tee /etc/modprobe.d/rtl8192cu.conf
Now my usb adapter isnt working at all. Please help

Thank You

[JeremyB]

Just do

Code: Select all

sudo rm  /etc/modprobe.d/rtl8192cu.conf
sudo modprobe rtl8192cu
