Some Missing SSIDs in Linux, but all available in windows

[jook]

I have a new issue on my laptop with it not showing all SSIDs available, when I click the WiFi icon on the system tray. (Some neighbours SSIDs do show) This has happened to me in two locations now, when I wanted to connect. I booted into windows and the SSID I wanted was there and I used it fine. Seems it is not a hardware issue. I also booted with a live USB with Kubuntu 24.04 and had the same issue.

I am currently running Kubuntu 24.04 and am up to date.

Are there settings in KDE that say not to display certain SSIDs for a specific reason? Anyone got any idea where I can start to troubleshoot this?

Thanks for any help.

Here is my WiFi hardware:

03:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)

DeviceName: Intel Wireless LAN + BT

Subsystem: Intel Corporation Wi-Fi 6 AX200NGW

Flags: bus master, fast devsel, latency 0, IRQ 77, IOMMU group 13

Memory at fc800000 (64-bit, non-prefetchable) [size=16K]

Capabilities: <access denied>

Kernel driver in use: iwlwifi

Kernel modules: iwlwifi

Generally, if you don’t see a SSID you know to exist, it’s because it is marked (on the host network) as hidden.

When I log into the router wireless settings, it is labeled as shown. I can also see it with my phone and windows on the same PC.

if dual booting, you might try disabling Windows fast-restart. it can mess with firmware, which might not be loading properly when booting back to Linux.

it won't be something set in a KDE setting , it will be a hardware/driver specific setting or bug. Which ones, I don't know.

One area might be the chip's power saving modes, perhaps. But it likley will involve some digging and trial and error. However, I suspect that this might already be disabled by default
