What do you want it to do - internet access but anything else?

If it's just the internet, then try these instructions:

start up you Pi, and log in.
start up the LXDE GUI ("startx") if it's not configured to start automatically
double click LXTerminal and type ifconfig - is wlan0 listed there are one of the network devices alognside "lo" and possibly "eth0"? If so - good
double click "WiFi Config" - there are 3 tabs - click the middle one "Manage Networks" - can you see your WiFi network listed? If so, move on, if not click the scan button.
Once your home network is listed, double click it, and enter your WiFi password in the "PSK" line. Press save.
Now go back to the main view of "WiFi config" and click the "Current Status" tab.
Click the "Network" dropdown, and hopefully that will show your home network - if so click it, and after a few seconds, it should all be working, and you should be able to access the internet

Obviously this assumes you have WiFi access to the internet already provided by your broadband hub.

If any of the above steps go wrong, let me know which one did, and what the problem looked like.

It keeps dropping the network every time I set it up then it drops again. I've rebooted it twice still no luck, any suggestions?

Are you plugging and unplugging either ethernet or the wifi dongle? I've had similar problems due to ifplugd which manages hot pluggable interfaces. If the ethernet and wifi will be connected all the time, then you can disable ifplugd for these by editing /etc/defaults/ifplugd, changing what you see to the following:

Code: Select all

# This file may be changed either manually or by running dpkg-reconfigure.
#
# N.B.: dpkg-reconfigure deletes everything from this file except for
# the assignments to variables INTERFACES, HOTPLUG_INTERFACES, ARGS and
# SUSPEND_ACTION.  When run it uses the current values of those variables
# as their default values, thus preserving the administrator's changes.
#
# This file is sourced by both the init script /etc/init.d/ifplugd and
# the udev script /lib/udev/ifplugd.agent to give default values.
# The init script starts ifplugd for all interfaces listed in
# INTERFACES, and the udev script starts ifplugd for all interfaces
# listed in HOTPLUG_INTERFACES. The special value all starts one
# ifplugd for all interfaces being present.
INTERFACES=""
HOTPLUG_INTERFACES=""
ARGS="-q -f -u0 -d10 -w -I"
SUSPEND_ACTION="stop"

I assume you are in the GUI (startx) and you are using the WIFI configuration utility.
Be sure your pass phrase is typed correctly and be sure to click save.
Make sure the WIFI encryption matches in the router and the RPi setup. TKIP or CCMP(AES).
Note if your router is set up for AES encryption then make sure the encryption field on the RPi is set to CCMP.

Either one of the above will make the WIFI attempt to connect over and over with no indication of what's wrong.
Unless specified otherwise my response is based on the latest and fully updated Raspbian Buster w/ Desktop OS.
