Settings Spontaneously Changed Without Warning

[dumbWaiter]

I have two VDSL lines, each serviced by a DM200.

Yesterday, my internet connection went down.

I subsequently discovered the settings on each had somehow become changed:

• One DM200 had reverted to factory default.
• The other had lost its VLANID.
• The region on each was erroneously set as 'Switzerland'.

How could this even be possible?

Has anyone else experienced similar?

After ruling-out 'black magic' the ONLY answer must be third-party interference i.e. I've been hacked.

The modem fully 'reset' has a static IP address; from there the second modem 'partially reset; is listed in 'attached devices' identifiable by its given name prefix 'DM200'.

I believe there is a weakness on the modem's public-facing side, which has been exploited.

Is there a way to bring this to Netgear's attention?

Good Luck.
