16.04 New Install won't connect to wifi

Question

Did a fresh install of 16.04 and can see my wifi router as well as my neighbors'. When I put in the password, it won't connect and asks for the password again. Searched the web for answers:

Tried the fix to stop the mac address changes,
Restarted network-manager a bunch of times,
Made sure the wireless driver was updated.
Tried a usb install of 12.04; it wouldn't connect either.

Output of lspci command:

Added a post where I linked to the output file for the wireless-info script.

Tried to start the wifi using nmtui but it did the same thing.

Tried to copy and paste the password into network-manager, no difference.

See my comments below on the stuff I tried tonight.

What happens when you type (from a command terminal) nmcli con wifi con [name of wifi network], replacing "[name of wifi network]" with the name of the network you want to connect to. (They may only work on 16.04.) Do you get any error messages? — TSJNachos117, Oct 13 '17 at 01:07
Comes back and says at the bottom 'wifi' is not valid 'connection' command — Jim Snider, Oct 13 '17 at 01:18
@AmrAyman where is this network log? Jim Snider, we most likely need hardware information. Run the wireless info script and [edit] your question to post the results, please — Zanna, Oct 13 '17 at 03:51
Please [edit] your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. — Pilot6, Oct 13 '17 at 08:42

Tried reinstalling the bcmwl-kernel-source and same results.....still keeps asking for the password. — Jim Snider, Oct 26 '17 at 10:58

Re-installed 16.04 last night with one big change. Found out that my router was set for 802.11n only. Reset it to allow older connections and wifi worked just fine.
