I have Manjoro gnome version dual boot with windows 11. Wifi wasn’t working so I ran
sudo sed -i ‘s/3/2’ /etc/NetworkManger/conf.d/default-wifi-powersave-on.conf
Now the wifi button is gone on linux and windows and I dont know what to do
You changed some value in that file (presumably)
Undo that change.
Why did you not use some visual editor to alter that file?
What do the contents of that file look like now?
cat /etc/NetworkManger/conf.d/default-wifi-powersave-on.conf
mine is:
[connection]
wifi.powersave = 3
and it works that way and always has
You set it to “2” instead of “3” - revert that if you think that that was the reason for your problem.
What was the reasoning behind that change?
(possible XY problem)
Edit the file. The content should be like this:
[connection]
wifi.powersave = 2
You can also run nmtui from Terminal to edit or activate the connection.
This might suggest you have inadvertantly broken your wifi fuctionality. Configuration made in Linux typically has no effect on Windows, however, the reverse is possible, if Windows Fast Startup happens to be enabled, for example.
If you expect help with this issue, more information may be needed. Please provide your system information as described (below) to allow others to help further.

Work with us, not against us
It is important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem. Please also be prepared to provide output from commands if/when asked.
Simply waiting for others to ask you questions is counter-productive – typically, nobody has a 
at their disposal – and your clear, concise and accurate input is often relied upon in order to help you.
Please help others to make informed suggestions based on information you provide.
System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; 
Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:
Suggested inxi command (use either):
inxi -zv8 |
(short-form) |
inxi --filter --verbosity=8 |
(long-form) |
inxi man pages |
(manual) |
Running `inxi` within a `chroot` environment
- Add
--color=0to the long-form command, or… - Change the short-form command to
inxi -zv8c0
