I'm on fibre so perhaps it's different. If I put in a wrong password, then factory reset with the long button hold, the password comes back along with resetting all other settings like WiFi SSIDs etc... My router isn't connected to the web, just my test machine so there is no communication externally. However, I will do some more extensive tests, I believe it's flashed in to the firmware.
Well I never, you are right ScottHelme the Bright Box 1 router after reset to factory default, it is hard coded with the customer registered username and password and is all setup for connection to EE broadband with MTU: 1492 - I like to use MTU: 1500
Also Under
Status it has my Broadband Username: surnamenumber.orangehome.co.uk@fs
Also after factory default found this odd DNS reading... I did Reverse DNS Lookup = DNS-28.orangehomedsl.co.uk
My Bright Box router has the Orange logo on it not EE.
Primary DNS 87.237.17.200
Secondary DNS 87.237.17.168
First I used the router settings software configuration backup at,
Advanced Set-Up > Accept > Tools > Configuration.
Backup
Use the button above to save the routers current configuration to a file on your device.
Restore
Use the button above to restore your router to the original factory settings.
I did the hardware factory default reset with a pin at the back of router and used the router software Factory Default at,
Advanced Set-Up > Accept > Tools > Factory Default.
Do not turn off your router, please wait until default configuration has been applied.
