Wi-Fi adapter not powered up after sleep

Modern laptops Have just S0 state with no ability to change it to anything else.

What about turning power save off in the network adapter settings?

Do you have a home network? If so, can your desktop still see the laptop whilst the laptop is in S0 Modern standby? If so, you have set up Connected standby as you say.
Enable or Disable Network Connectivity in Modern Standby - TenForumsTutorials

I assume that the command

Code:

PowerCfg -a

confirms that
- your Desktop has S3 Sleep but not S0 Modern standby [S0 Low Power Idle]
- your Laptop has S0 Modern standby [S0 Low Power Idle] but not S3 Sleep

I'm amazed that your Desktop ever had S0 Modern standby. I have not heard of a Desktop having that before.

Just to be pedantic for a moment to avoid confusion & misinterpretation, S0 Modern standby [S0 Low Power Idle] is not "Sleep". It is a glorified idle condition even though Windows confuses the issue by using the word Sleep in some S0 articles & system reports [S0 progresses in stages and later ones are sometimes called Sleep but they are not S3 Sleep].

I regard S0 as a curse [I have one computer afflicted by it]. Perhaps it might become attractive in a decade if hardware components' idle power consumption become so low that a computer can be left on all day using battery power. But at the moment, that is not the case..

The relevant MS article is Disabling modern standby - MSDocs but I had severe side-effects from that. That procedure suppressed S0 without, in my case, enabling S3 and it stopped my network adapters working correctly. It seems to me that your problem description [with S0 still enabled] matches my experience after disabling S0.

I have also seen the Reddit articles. They have undergone several changes over the years so the author must certainly be putting continuing effort into the subject. My afflicted computer's CPU is apparently unsuitable but I still look up the Reddit articles every so often to see if there is anything new. The latest version is significantly different from earlier ones and, if I have understood it correctly, it now just mimics the MS article. This is the latest Reddit article I have kept a link to
Getting back S3 sleep and disabling modern standby

My only potentially useful suggestions

1 I suspect that your network adapter[s] do not have drivers suitable for use with S0 but I would have expected that to cause them to remain fully on & using a lot of power during S0 rather than stop functioning at all afterwards.
- Do the network adapter makers provide alternative drivers?
- Might they have tech support contacts or user forums you could use to ask about the problem?
- They might not have written their drivers to cope with S0. Whilst that would not give you a solution at least you'd know the situation a bit better.

2 When I had a problem with network adapters not working correctly after S3 Sleep, I disabled them then re-enabled them because that was quicker & less disruptive than rebooting. If doing that manually works for you then perhaps using a variant of the batch script I wrote then would also help you.

Get the adapter name[s] from

Control panel,
Network & sharing centre,
Change adapter settings.

[For the manual procedure, I just right-clicked on the adapter, selected Disable, right-clicked on the adapter again, selected Enable.]

I then put the adapter name in this batch script:-

Code:

netsh interface set interface "%AdapterName%" disabled
netsh interface set interface "%AdapterName%" enabled

and ran it 'as Admin'.
- I found this to be less inconvenient that going through disabling-enabling the adapter manually.
- I only had a single WiFi adapter to worry about but I see no reason why the same approach would not work for multiple network adapters.


I wish you the best of luck,
Denis

The newer Mobile CPU’s and Bios’s do not care since they do not even look at that setting.

OMG I don't want a new laptop.

Yep.

Lemme guess ....... if I downgrade to W11, it solves the problem

That would be a upgrade.
