I know the username and password of my Cisco 2500 series wireless & ethernet controller and its IP address, but when I enter the IP address into a web browser (Firefox and Chrome) it states the location cannot be reached / connection cannot be established. The admin GUI showed up when I connected the router/controller to my laptop for the first time and I set up the admin username/password and IP address that way, but when I hit Enter/exited the GUI it sort of froze and didn't seem to close properly, so I am worried something may be broken now.

My laptop uses Ubuntu 18.04 linux and I have it connected via ethernet to the router, as well as a console cable from the laptop's USB to the router's Console port. I am able to communicate with the router through the linux software called "minicom" (see https://help.ubuntu.com/community/Minicom & https://help.ubuntu.com/community/CiscoConsole) and the enable command works, the debug command works, the config command works, but I am new to programming Cisco routers so I don't know what series of commands I need to "fix it".

Here is the system output:

    Could you paste the output of show run from your Cisco, and the IP address details of your laptop? Are you able to ping the Cisco but the web GUI doesn't work; or does ping also fail? – Jeff Wheeler Jul 5 at 13:47
