Specific WiFi network not found

[StarmanF]

Fresh install and the wifi configuration seems to be detecting a bunch of devices, just not my router, which it's right next to. I tried setting it up as a hidden device, it could not connect. My phone can use the wifi fine, so the signal is strong theoretically. I also looked up the firmware vs adapter in my laptop in this list, it's a Intel Centrino Advanced-N 6235. The firmware for it seems right. And it's not dysfunctional, it just seems to not want to see my router specifically, for seemingly no reason.

Any suggestions as to what I should try to fix it?

What about doing it manually? You'd have to disable NetworkManager, and, assuming it's using wpa, create a wpa_supplicant.conf file.

gives some steps to test to see if it's NetworkManager that's the problem.

What do you see with the following command:

# nmcli dev wifi

What do you see with the following command:

Same list, missing my router

Does your router have the option to not respond to a "Are you there" type of message". Some routers allow not responding to the SSID.

Second Question. Does another device that uses the router see the name?

Most wireless routers offer the option to disable SSID broadcasting as a means to ostensibly improve Wi-Fi network security since it basically requires the clients to know two "passwords," the SSID and the network password. However, the effectiveness of this technique is limited since it's fairly easy to "sniff out" the SSID from the header of data packets flowing through the router.

My phone can see it, I installed the same version of Fedora on another device, that too can see the router. Also my family uses it and this is an isolated issue.

Can you make the SSID visible and try to connect.

There maybe a mismatch with the Region settings between your router and your comp.
Are you trying a 5G network ?
If so, some computer WiFi cards won't see past channel 140, so lower your channel in your router to say 48 (the first one below DFS), and see if that works.
EDIT: I know the Ubiquity Antennae (cuz I use them) like to sit at channel 149+1 , which makes the 5G invisible to most older 5G capable comps.
