In Topic: Can I stomp on neighbours wifi?

My UniFi AP AC has all the channel/frequency stuff on auto and doesn't miss a beat, and I can see 3-5 other AP's with 1-2 bars at most times during the day.

If your AP isn't smart enough to do channel hopping seamlessly and transparently to your end devices, it's time for a new AP.

I'd have thought being an Amiga guy you'd have that well covered.


I do, I meant because of like questions like MS's about disabling DMA for the network card.

The article says "has DMA access to the system" without really explaining what that means.


from the following lines:

- it can arbitrarily read and write to any memory or storage on the system
- bypass disk encryption once it is unlocked
- read and write to the screen
- do all of this completely unlogged
- send whatever it finds out to wherever it wants, encrypted or not.

i took that for an explanation. what is misleading/incorrect/missing?


I just meant it would've just helped to talk briefly about what DMA is.

I wonder if there's just a way to disable DMA for your network card. That should solve it, from reading the semiacurate news article (thats a bad business name in hind sight, lol)


The article says "has DMA access to the system" without really explaining what that means.

Presumably, it means the management engine can tell the 8237 to initiate arbitrary DMA transfers, which obviously opens a can of worms.

You can't "disable DMA for your network card" because it won't work without it. In fact, you can't really use PCI or PCIe without DMA.

DOSBox is not the right choice for non-game applications. It is geared towards games, and does not fully implement file/record locking and other features used by productivity software.

Instead, try vDOS, it's geared towards non-gaming applications, supports copy-paste, and other stuff like that.
