I did a fresh install of Ubuntu 18.04 on a Dell Inspiron 5448 (previously I had Windows 10 on this computer). The wifi (Intel Wireless 7265) does not work with the live disk neither does after installation. I also tried two USB-Wifi Adaptors, one from Cisco (Linksys WUSB100 Range Plus) and one from TP-LINK (Realtek RTL8188EUS). The adaptors do not work either, but both work plug and play on my Manjaro XFCE installation at home (Kernel 14.04).

In the top right drop down menu of the Ubuntu Desktop I get PCI Wi-Fi OFF and/or USB Wi-Fi OFF, but clicking on the option Turn on does not have any effect. The Wi-FI settings shows No Wi-Fi Adaptor Found, although on the top of the window it is written Wireless 7265 (Dual Band Wireless-AC 7265). Both show as disabled (see below).

I already a attempted several instruction from several forums without success. I appreciate any help. Thanks!

The output of the wireless script is available here (with the TP-Link adaptor also plugged in).

After examining the output of your wireless script linked in your question, I believe you need to blacklist the dell-rbtn module:

sudo nano /etc/modprobe.d/blacklist.conf

Add the following line:

blacklist dell_rbtn

Also, make sure secure boot is disabled in BIOS.
