Can I block non-account owners from modifying the Advanced Wireless Settings?
On the wireless network that I completely pay for but share with my roommates, they've been logging into the Management Console (Advanced Settings) to lower our network from 5G to 2.4G and block my smart devices from connecting (unknowingly and without my permission). I've mostly secured the account now, but there's 2 remaining problems:
* I've set a custom Device Access Code. But this can be reset to factory default using a physical Reset on the modem. Can I block this physical reset (unwise, I know) or rather secure my current, custom Device Access Code?
* When talking to Customer Support, they ask for my name and phone number (both easily known by others...). Can I add additional security when identifying myself, such as my AT&T passcode?
Thank you in advance for any hints and help. Stay well!
