Have you tried iwconfig with the wifi turned off? I am not familiar with the network manager in xfce. Using Gnome, I keep wifi turned off all the time and use the Ethernet port for networking. I replaced the original wifi card so that I don't need non-free software if I should choose to use it, and I chose a card without Bluetooth simple because it was less expensive and I don't use Bluetooth on this computer.

Steve, I've considered you a calm and level-headed person. The amount of patronizing sarcasm seen here really surprised me. No matter, we all have triggers, don't we?
Those sources are too random, obscure and irrelevant when compared to the energy radiated by the Sun.


I was going more for the funny side than the sarcastic, but the radiation from radon gas that accumulates in basements presents a clear risk of cancer if not cleared out by good ventilation. I doubt that any one that contracted lung cancer from it would consider it obscure and irrelevant.

I would also argue that the inescapable radiation from K40 and C12 in our bodies can be more of an influence than the sun, which is not shooting beta radiation at us, but only UV rays that can be avoided or minimized with sunscreen and clothing. Potassium and carbon is pretty tough to remove from your body... https://en.wikipedia.org/wiki/Backgroun ... _and_water

You may also laugh off cosmic rays, but many authorities do not: https://en.wikipedia.org/wiki/Backgroun ... _radiation

And before we cherry pick one country to represent all with so-called plummeting life expectancies, somebody concerned with facts instead of fear-mongering would look at other countries before making such claims...how about Japan? They're much more concentrated in urban centers awash with radio signals than US citizens, so they must be dying much earlier as the signals increased, right. Right?

"fitness"? i'm sure you mean "health"?

i wouldn't have the bed right next to the router.
mine is in the kitchen and there's a (not very solid) wall between it and my bedroom.
i would even consider switching it off at night, or when you don't use it.
same with mobile phones.

and the IP address has nothing to do with emissions.

As long as you wrap yourself in tinfoil at night when you sleep you don't need to worry.

First reply said it all. You can confirm objectively that you aren't sensitive to the radio signals. You likely should speak to a doctor. Though the technical problem remains, if OP wants to set his system up to reduce emissions, why should we stop him? Shame on you.

Well I don't know about you, but I can get my steps in on my fitbit only when I've locked myself in a Faraday cage.

Probable mistranslations aside, has the op tried a tin foil shield between him and his wifi card? Shouldn't be a problem so long as you don't go out in public (although, in today's day and age, with all the wifi infrastructures, there's probably no way to avoid the issue). Or, just using ethernet?

Also hoping you see a doctor. (Is there a medical term for this condition yet?)

I blacklist the bluetooth modules to disable that "feature" on my machines:
Code: Select all
empty@buster:~ $ cat /etc/modprobe.d/blacklist.conf
btusb
bluetooth
uvcvideo
empty@buster:~ $

The uvcvideo module is for the camera but I don't suppose you need that :)

The transmission power can be knocked down at boot with a udev rule, see this example on the ArchWiki:

I'd be equally concerned about what it's doing to the nutritional value of your food. I remember when this study came out and was first published in acresusa.com. I've never owned a microwave and never will. Don't have any wireless devices either.

Because the next step these people always take is to try and ban wireless in the workplace and in schools for everyone without a shred of evidence that it affects them, that's why. Shame on you for not keeping up with current events!

I would be 100% on their side if they can provide peer-reviewed, non p-hacked studies to show that it is harmful...but am still waiting.

Disabling bluetooth and reducing wireless power seem to be fairly reasonable things to do even if the OP's reasoning is specious, IMO.

EDIT: damn it, just read the OP again...

@OP: no, the wireless card does not transmit if you don't use it.

If the card uses non-free firmware (most do) then uninstall the firmware to render the card non-functional.

Alternatively, remove or replace the card. (I've noticed a lot of wifi-bluetooth combo cards have pretty terrible bluetooth reception, so a non-bluetooth replacement might not be the worst option.) Also, don't some bluetooth modules on cards like those use wifi antennae? Maybe it would help to just unplug those and see what happens. 1dBm sounds intensely low anyway.

Just in case I should clarify. My statement was that the op can easily confirm that they have no actual sensitivity to the radio waves and their problem is psychological.
