  • Rf interference. Similar to having multiple microwaves running near your router, or those old rf based baby monitors.

    Congested the 2.4 or 5gz spectrum with noise causing noise and retransmits or outright stopping the wifi from working.

    If you have an old radio that does AM find a AM channel that isn’t broadcasting and bring it near your router. You can actually “hear” the noise those things are putting out.










  • I think Secure boot is intended to check that the boot loader itself is signed.

    This is a way to mitigate viruses and malware that infects the boot loader so it can reinstall itself if it’s removed by AV, or something else.

    If you can create a boot loader that is signed in such a way that secure boot can’t tell it’s invalid then you can do some nasty stuff.

    Closest analogy I can think of is verisigns private key being leaked and there’s no fast and easy way to revoke and replace it without wreaking havoc on currently installed OS’s machines.
