I installed Elementary v5 on a Dell Latitude E6410. The program indicates that it recognizes the wireless network and is connected, but when I attempt to access any site it displays the message "unable to display this website" Also, when I search for networks in my area my network is listed twice as "network name." and "network name 1".
Welcome to the Elementary OS forums!
What happens if you go to Applications -> Terminal and issue the command
nmcli d wifi list
If the result of that command has the data you expect in the following areas: SSID, CHAN, BARS, SECURITY that is the first step. For the second step, what are the results of this command (also in terminal).
ping -c 3 18.104.22.168
Please let us know.
