Welcome to LQ!
If the wired connection is working use that to get the updates for now.
About your wireless, if you could post the details of your adapter that is going to help us to help you fix the problem,
so in the terminal/console type:
$ dmesg | grep -i wlan
$sudo lspci -v | grep -i wlan
Post the results inside the code
