- Open the Firefox Developer Tools panel (right click anywhere and select "Inspect Element")
- Go to the Debugger tab in the Developer Tools panel
- Find and open the "ui.min.js" file, normally in the path: Main Thread > 192.168.1.1 > js > ui.min.js
- Click the "{}" or eyeball symbol, normally in the bottom left corner of the file, to make it easier to read
- Find the "validateSsid" function (on my router as of 23 March 2020, on line 9827), it should resemble:
a.validateSsid = function (b, c) {
(1 > b.length || 32 < b.length || !/^[0-9a-zA-Z\!\"\#\$\%\&\u2019\'\(\)\*\+\,\-\.\/\:\;\<\=\>\?\@\[\\\]\^\_\`\{\|\}\~\ ]+$/i.test(b)) && a.errorMessages.push(c + ' Service Set Identifier must consist of 1 to 32 printable ASCII characters.')
};- Set a breakpoint on the line of code inside the function (by clicking the line number on the left side)
- Click "Apply" on the Verizon Fios webpage and the breakpoint should pause to show you the value of the SSID name you're trying to save (above where you set the breakpoint in the "ui.min.js" file)
- When the SSID name you're trying to save (2.4 or 5 GHz) shows up as the value, normally for the variable "b", open the Console (normally at the bottom of the Firefox window, but also available as its own tab next to the Debugger tab)
- Change the value of "b" to any normal SSID name for the Router to accept it (this will not change the actual naem its saved as), for example:
b = "Chicken"- Now you can remove the breakpoint and click the "play" button, normally at the top of the panel on the right side of the Debugger, and the Router should save the settings!
