Windows 10: Why does my PCIe wifi card disconnect every time I shut down my pc?

I have searched for months to find the answer to this and nothing has worked. I've also never found someone with the exact same problem as me. I've looked on forums, youtube, reddit, etc and nothing. I tried buying a new PCIe adapter and a usb adapter, I've tried uninstalling the device multiple times, resetting the network, rolling back drivers, updating drivers, and ensuring the the computer cannot turn off the device to save energy. None of this has fixed the problem. I'm genuinely getting frustrating because I know the way I turn off my pc cannot be healthy for it in the long run. In order

Reliable plug-and-play Mini PCIE WiFi card for laptops?

Hi all - I own 2 older Acer laptops with Broadcom WiFi cards that all have issues with WiFi randomly disconnecting, or NOT automatically reconnecting upon wake-from-sleep or on boot. I've seen several family member's laptops with the same issue...also with older Broadcom cards.

The only way to fix the random disconnections when they happen is by running the WiFi troubleshooter, disabling and re-enabling the WiFi adapter, or sometimes restarting the whole machine. I've tried every single driver I can find, and tried various suggestions for settings changes (turning off 'allow Windows to turn this device off to save power', for example) and they all still do this. They are all older laptops (Win7 or Win8-era) that have been upgraded to Win10.

So....to work around this as it's driving me crazy, are there any suggestions for a good plug-and-play Mini PCIE WiFi card I could put into those laptops that isn't going to break the bank? Hopefully replacing the card with one with a completely different chipset would do the trick?

Any decent Realtek/Ralink/Intel/Atheros Mini PCIE cards out there that could solve the issue? Thanks for any suggestions!

 

Recommendation for WiFi usb / card

If you have a desktop computer I would STRONGLY suggest a PCIe adapter rather than a USB adapter if you go with WiFi 6. The only USB WiFi adapters that I have seen thus far use a Realtek chipset which is reported to have some serious flaws. In my own personal experience, I have tried 2 of these and returned both, getting performance worse than other WiFi 5 adapters and constant disconnects even 10 feet from my WiFi router. If you go with a USB adapter, I would suggest a quality WiFi 5 adapter. One more note: Should you decide to go with a WiFi 6 PCIe adapter, I would suggest a WiFi 6e model. They actually cost no more, and they are one step up just in case you ever go to a WiFi 6e router.

 

Windows update: one PCIe slot and one GPU kaput

Memtest86 is good, but no RAM tester can detect all possible RAM failures. I would suggest that you adopt a slow and careful step-by-step approach to troubleshooting this clear hardware issue. I would suggest that you strip the PC to the bare minimum. Unplug all external devices except monitor, mouse, and keyboard. You've already removed the GPU, so remove all but one RAM stick (and try other RAM sticks too). Remove unnecessary PCIe cards (extra USB ports cards, WiFi cards, for example). If it fails in as stripped-down version as you can achieve then I'd look at the PSU, and then the motherboard. This isn't a software issue though.
