WI-FI Sleeps

[KevHead]

When my PC sleeps so does my WI-FI.

Some of my apps need WI-FI to updated, do backups etc. even when my PC sleeps. How do I keep the WI-FI awke.

KevHead — in normal Windows Sleep, the PC deliberately powers down most hardware, and Wi‑Fi/network activity stops by design, so apps can’t keep backing up/updating while the PC is truly asleep. epends on what sleep mode your PC supports:

1) Check which sleep mode you have (this decides everything)​

Open Command Prompt (Admin) and run:
powercfg /a

If you see Standby (S3) (classic sleep)​

You cannot keep Wi‑Fi active during sleep.
Use one of these a
Option A — Keep the PC awake, but turn the screen off (best for backups/updates)

1. Settings → System → Power & battery
2. Under Screen and sleep:
   • Set Put my device to sleep = Never (at least “When plugged in”)
   • Set Turn off my screen to a short time (like 5–10 minutes)

Option B — Let it sleep, but have it wake up to do backups/updates

1. Control Panel → Power Options → Change plan settings → Change advanced power settings
2. Sleep → Allow wake timers = Enable (Plugged in)
3. In Task Scheduler, set your backup/update task:
   • Conditions tab → check Wake the computer to run this task

This way it sleeps most of the time, wakes to run the job, then can go back to sleep.

If you see Standby (S0 Low Power Idle) (Modern/Connected Standby)​

Your PC may support staying connected in “sleep-like” idle. On some systems you can enable it here:

1. Control Panel → Power Options
2. Change plan settings → Change advanced power settings
3. Expand Sleep
4. Look for something like Network connectivity in Standby / Allow network connectivity during connected-standby
   • Set it to Enabled (Plugged in)

If that setting doesn’t exist, it’s usually because the hardware/driver/OEM doesn’t support it (or the OEM has locked it down).

2) Also do this (helps prevent Wi‑Fi from powering down too aggressively)​

This won’t make S3 sleep “stay online,” but it can help stability while awake/idle:

1. Device Manager → Network adapters
2. Double-click your Wi‑Fi adapter
3. Power Management tab:
   • Uncheck Allow the computer to turn off this device to save power

3) Tell me these 2 things and I’ll give the exact best setup​

1. What does powercfg /a show (paste it)?
2. Are you on Windows 10 or Windows 11, and is this a laptop or desktop?

Once I know S3 vs S0, I can tell you the best “sleep-but-still-updates” approach for your machine (usually: don’t use S3 sleep, or use scheduled wake for backups).
