Missing wifi

[udidwht]

Just noticed that my wifi option down in the taskbar lower right if I left click on volume/network icon is gone. It was there the other day but not now. Nothing showing in device manager as well for wifi. I'm connected currently via LAN and that is seen within device manager as Realtek Gaming 2.5Gbe Family Controller.Take that back... Just noticed if I select in device manager (show hidden devices) the wifi is listed but grayed out....

Motherboard is an MSI Pro B760-VC-Wifi II

Bluetooth works great. Just bought this system less than 1 month ago. Rebooted several times but same results.

maybe windows update borked some stuff...
if nothing works back up files and do a format and reinstall windows
something clashed in the registry...

its only a month old should be easy...
if it doesnt work.. maybe send back to the place you bought
will be under warranty

Update:

Opened the case cleared the CMOS then rebooted PC. Wifi is now showing in device manager and also down in the taskbar if I left click on vol/network.

Not sure as to why it suddenly disappeared.

@udidwht
are you using standby/hibernation/fast boot/ErP?
sometimes those things "disable" the wifi chips, but havent seen it on MSI/AM5

@Hyderz
not sure why you would recommend a fresh install before even trying other/easier things, heard of rollback?
i do tweak/change/install many things in just a week, than i would ever care to do a clean install, let alone after a month is gone.

for me it wont matter, as i image the sys regularly, but assuming that ppl have a "naked" system just because its only a month old?!
...
and thats ignoring its a prebuild rig, so shipping a whole pc isnt that cheap or fast.

well its the one of the fastest way i know if something is not working properly in windows... a fresh install of windows allows me to see if windows is the culprit...
of course rollback could work... but in all my experiences... it never worked for me... and ive wasted time ...

as for sending it back to manufacturer, sure that was my bad... i should have asked more if op bought it locally or online...

Could be windows put the device in power saving mode. Should check in device manager.

The other place to check is Control Panel->Power Options. Select the current power plan and then Change plan settings->Change advanced power settings. There are options for Wireless Adapter Settings->Power Savings Mode. Select Maximum Performance, the wifi will then not turn off at any time.

All that is off and/or disabled.

All off and/or disables. So is the selective suspend within power options. One of the first things I did when I got the system up and running.

I just blame Windows.

Sometimes the network is connected icon in the taskbar shows I'm offline on a laptop that I use from time to time, even though I can connect to a website without any issues.

I wouldn't really worry about it. If you're on the internet without any issues, just blame Windows and move on. If it really bugs you, generally just a restart of Windows should fix it.

In my case the wifi was not shown and/or listed anywhere. Several reboots did not resolve the issue. Only resetting the CMOS worked.

Uninstall the NIC and let Windows redownload fresh drivers or Reset the Network stack.

How to Reset the TCP/IP Stack on Windows 10 and Windows 11

"Reset it to default" isn't a cliche like "Have you tried turning it off and back on again," but it works nearly as often.

A CMOS reset resolved the issue.

A CMOS reset resolved the issue.

It's very odd that device manager showed it greyed out even if it was called by the generic name prior to reinstall of the named driver.
Sometimes a reinstall of an updated brand name driver will correct things and sometimes just clearing the driver stack will do it.
You should keep that driver updated and keep it on hand.
Sounds like a Windows update was to blame. (seeing that you have the most recent bios)

The solution worked but it's still an odd one.
I'm wondering if you took the adapter out, rebooted, then shutdown, and put it back in would have accomplished the same thing as the bios reset?
It could be wifi 7 is buggy and needs development?

No way to remove wifi on this board it is incorporated into the motherboard.

@jsfitz54
not odd, had in on Gb boards using intels wifi/bt, which would stay off,
unless the cmos was cleared, not even flashing it bring it back.

Here's another odd one...

The system is an MSI pre built R2 B14NUC7-095US (MS-7D98) which uses the MSI Pro B760 VC Wifi II motherboard. After purchasing it I figured I'll check to see if the BIOS was to date...it wasn't. Or so I thought... I downloaded the following BIOS and installed it. Process went flawless using M-Flash. Used the following BIOS...https://www.msi.com/Motherboard/PRO-B760-VC-WIFI/support#bios

Only to find out the correct BIOS is the following....

https://us.msi.com/Desktop/Codex-R2-14th/support?sku_id=94270

System is running beautiful. And thinking back I attribute the wifi issue to not clearing the CMOS after updating the BIOS. The system information shows BIOS as AMI B.A0 02/28/2024
