Windows 10: "No Internet, Secured" when waking up from sleep/hibernate mode of ThinkPad P14s Windows 11

Why do I often encounter the following problem when I wake up from sleep/hibernate mode of Windows 11 on my ThinkPad P14s? My wifi connection shows "No Internet, Secured". I switch off and switch on the Wifi or disconnect and connect the network but none of the solution works. I have to restart my computer in order to get back internet connection. This is very irritating. Is there a way to solve this issue besides restarting the Windows 11?

Waking from sleep by keyboard

Windows 11 with last updates. Lenovo ThinkPad laptop does not wake up from the keyboard or mouse if hibernation is enabled. When hibernation is turned off, waking up from sleep via the keyboard or mouse works. However, when hibernation is turned off, the hotkey on the Logitech K860 keyboard that sends the laptop to sleep stops working. How to make both the keyboard and mouse work in sleep mode, and the sleep hotkey in work mode at the same time?

As if that "sleep" function actually send laptop to the hibernation. But on the old laptop it worked properly

 

Hibernate mode Vs Sleep Vs Hybrid sleep.

I'm starting to lose track of what we're disagreeing on. I can't say what was on the mind of whoever designed the technique in the past, but today it is a tool available to any supporting platform where the users need it. Hybrid sleep is functionally a suspension to disk without clearing the ram, at its core it is a hibernation. Arguing which method is for which platform is -with all due respect- a waste of time. I would agree to the argument that Hybrid sleep is more versatile than simple hibernation, though, but that doesn't make hibernation a non valid method of suspension on desktops. And if someone intended for long down-times or expected power loss, the differences between hibernation and hybrid sleep become inexistent.

For the frequent blackouts part, we have to consider the scope of the issue here: whoever opts to use any suspension method, hibernation, sleep or hybrid sleep, does so explicitly to avoid shutting down the computer (for whichever reason they wanted). Anecdotal example: I'm off to work in the morning, but I do not want to close all the software and web pages I have open (and they can be many) and restart them later, so I have the choice of either sleep or hibernate (or hybrid methods), but with any S state less than 4, I run the risk of a blackout forcing me to what I avoided shutting down for, so I elect to use hibernation (or hybrid sleep, of which the hibernation part is what's needed).

A UPS is indeed a must have, but alas, not all of us live in the first world!

VRAM isn't wiped post-wake up, per se. The only way to wipe the entire memory is relieving if of power. Hibernation does have that effect in the suspension process (going into hibernation), upon waking up it repopulates the memory with what was occupying it before turning off (though I don't know if it was actually this simple).
What was I referring to in my previous post is Windows' memory manager's functionality. When a process is closed (eg: Alt+F4ed the main window, killed in task manager, etc), all its memory heap is then freed up for other processes to use. So, any memory that is used when a computer wakes is for actually running processes, waking up won't reserve memory for anything else (other than hardware, I guess?)

Computers can be weird. I once had a recurring issue with Microsoft's Security Essential where it starts eating up all my ram after waking up from sleep. And I'm talking about 20GB of physical memory! Still don't know what caused that bug though. Couldn't reproduce it in later Windows installations on the same hardware either.
And don't get me even started on those cheap Chinese hardware!

 

No internet when computer wakes from sleep mode

No Internet when computer wakes from sleep mode or from cold start until I disable the Local area connection and then enable it.

When I run the diagnostic after it fixes the connection it says this: Local Area connection doesn't have a valid IP configuration - Fixed

But its not fixed. Every time I wake my computer up from sleep mode after its been in sleep mode for a few hours I have to disable and then enable the Local area connection.

When the computer wakes up it has a yellow triangle warning of limited or no internet access. So I have to do the above every time I wake it up.

Things I've done so far: Update drivers, No fix.
