NetworkManager does not detect the nearest network

[ian848uig]

I have the problem that NetworkManager does not detect the name of the closest network, NetworkManager only detects the Router that is about 7 or 8 meters away (Approximately) and is unable to connect to it or in some cases it does not appear.
The Wireless Adapter that my PC does not detect, as I said previously, the extender's Wifi network.
I connected through USB Tethering on my Galaxy S20 FE 5G but on Sunday I switched from the official firmware to an unofficial LineageOS 20 build that is stable and Open Source, but the "USB Tethering" does not work. It is not detected by Gentoo nor by a Debian installation that I have. (I came to the conclusion that the problem may be some LineageOS configuration). I was also compiling the gentoo kernel several times, selecting Qualcomm/Atheros drivers, but it didn't work.
so I no longer have the means to have internet. On my main PC, I also haven't finished installing gentoo, I still need to get KDE Plasma to work, which with the Nvidia driver. Proprietary does not start and I am left with the SDDM black screen after logging in with it. (I would have Try the Nvidia Open driver (https://github.com/NVIDIA/open-gpu-kernel-modules). but the driver is another separate issue.

CONCLUSION: I have problems with my wireless adapter and NetworkManager and it does not detect the nearest network/extender. and only the one from the router that is further away and cannot be connected to it.
Note: I don't know how to extract logs from the screen so a little help wouldn't hurt on that topic.
Extra: also to include, I disconnected the PC for 2 to 3 minutes but it didn't work.

ian848uig,

You can save logs to a file, put the file onto USB and move it to somewhere you can post from.

Asa worked example,

Thank you for the answer, but I will take it to implement it, then the PC keyboard is no longer detected in the POST (Power-on Self-Test), and I am trying to restore the BIOS, because I do not have access to the CR2032 battery because the Crystal is sealed and they are not screws that hold the lid glass, so this inconvenience will delay in publishing the log (since the keyboard is no longer detected by the UEFI firmware). This happened after disconnecting it 4 hours ago and connecting it after 2 minutes.

UPDATE: After figuring out how to remove the cover and access the battery, I put it back in and the keyboard was detected, although I will be configuring the bios right now, I decided to disable fast boot to avoid future problems.
I will continue with capturing the log and uploading it.

I hope it helps, also without being able to connect as I will do to update, if as I said before, USB Tethering no longer works for me.

I tried what was suggested, I set the USE wep tkip variable and it detects the extender network, and I was able to connect

ian848uig,

That means that your WiFi tetwork offers WPA security, which is no longer secure.
It should be changed to WPA2 or WPA3 if possible, then you can disable USE=tkip.

It is a TP-Link Extender, it is not possible for me to change it in the short term. Also with USE wep I detected the extender, here are some specifications:
Model/Hardware Version: TL-WA850RE v4.0
Firmware Version: 1.0.0 Build 20171218 Rel. 59722.
I also updated the Firmware a long time ago to the latest version available. (You could try OpenWRT as a replacement for the Firmware, but according to the Wiki, its RAM and storage are low)(https://openwrt.org/toh/tp-link/tl-wa850re). so I'll leave it as it is.
And about WPA, I don't have that much concern. In the future I will surely change the extender. (I think it started to have errors a while ago, because sometimes when it is downloading for a long period it disconnects by itself.)

ian848uig,

As long as you are aware of the security situation and you make an informed decision. Thats all that matters.

In the meantime I will try to use some security measure like firewalld and configure Firefox.

I only have to make KDE Plasma and SDDM work, which with my Nvidia GTX 1050 TI refuses to start KDE Plasma.
I will have to open another post to solve the KDE Plasma problem.
