No internet connection using wifi

I just downloaded the latest edition of Ubuntu Mate and it look great but I cannot seem to get a stable internet connection via wifi. I have tried everything and now I hope someone can help me. At first when I chose my router from the list and entered the password, nothing happened. I tried this several times. Then I deleted all connections and made a new wifi connection, entering the SSID manually and entered the password again. Now I see the connected wifi symbol but I still have no connection. I tried the ping command to google and I started FF. I also tried to connect via bluetooth from my phone. Now I don’t know what else to do.

Now I see that I was asked to enter details about my wireless card. I don’t know exactly what info is necessary but the name of the card is Qualcomm Atheros. Product: QCA9565 / AR9565 wireless network adapter.

Edit: I posted this on askubuntu.com but i can’t seem to get any help there so I’m trying here instead.

Hi
Please post the output of the command:

inxi -NZ

Cheers

Network: Card-1: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter
driver: ath9k
Card-2: Qualcomm Atheros QCA8172 Fast Ethernet driver: all

Thanks for your help. Cheers

Okay, I'm sorry to say google was less helpful than usual.
I've no idea if this will work but try and enter the following commands in a a terminal:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

Then:

sudo modprobe -r ath9k && sudo modprobe ath9k

Cheers

Okay, I will try that but can you please just explain what these commands actually do? Is this supposed to edit a file called ath9k.conf?
I want to understand what I’m doing.

Cheers

First: It’s creating a file which holds the configuration options for the driver ath9k used by your wifi card, telling it not to do hardware crypto (I guess)
Second: it reloads the driver

Great, I will try that. Thank you very much :slight_smile:
