Look in the additional drivers app. There should be a driver there. If not give full details of your wifi chipset.

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list

Thanks.

Also do you dual boot the system?

Thanks

Additional drivers should have lock sign on it. You use your user password to open it. Or don't you have an admin account?

Your wifi has an IP. If you run:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

Does the web work ok?
