I'm not experienced in WiFi troubleshooting. This is the first time I have this kind of connectivity issues. So far I've discovered that every time the connection gets interrupted, this blue circle/loading thing appears in networks tab:

I ran a network stability test for 1 minute, this is the result:

Wifi works fine on windows and all other devices in our home.
I can't test the wired connection as the router is too far away.
I know there are commands and log files that would help, but I have no idea where to start and what to look for.
Any help will be appreciated.
 


My first thoughts are
Have you installed it to your machine as
1]direct to harddrive [multiboot] in which case I would suspect wrong wi-fi drivers... or
2] in a VM/VB in which case you will not have direct access to the wi-fi, only via a bridge to the main OS

I'm dualbooting. Windows is on one ssd, linux and grub on another. If you are right about wifi drivers, how do I fix them?

first we need to find which chipset is in the wi-fi,
first install inxi Im not up on Nobara but I think it's fedora, in which case [you will need an alternative methos of internet connection]

sudo dnf install -y epel-release

sudo dnf install -y inxi

then run inxi -Nn copy and past the report back

when trying to install epel-release:
Code: 
No match for argument: epel-release
Error: Unable to find a match: epel-release

inxi -Nn:
Code: 
Network:
  Device-1: Qualcomm Atheros AR9462 Wireless Network Adapter driver: ath9k
  IF: wlp8s0 state: up
  Device-2: Realtek RTL8125 2.5GbE driver: r8169

What is the output of...

nmcli dev wifi list
and
ip add

You don't want the epel stuff for Fedora/Nobara, just install the rpmfusion packages.

Click to expand...
Code: 
Package rpmfusion-free-release-39-1.noarch is already installed.

nmcli dev wifi list shows a list of networks around me. There are 14 but all of them including mine are listed there twice.
Code: 
IN-USE  BSSID              SSID            MODE   CHAN  RATE        SIGNAL  BARS  SECURITY
        (bssid)            (my_network)    Infra  36    405 Mbit/s  77      ▂▄▆_  WPA2
*       (bssid)            (my_network)    Infra  6     130 Mbit/s  39      ▂▄__  WPA2
First one was orange, second was purple in the command prompt.
bssid of both is nearly identical but the first one ends in :AD, second ends with :AA

ip add:
Code:

update: I ran the command again few seconds later and now the first network in the list is IN-USE.

That's OK. They will usually have different bssid's, and they will always be on different channels.

Obviously higher bars mean you'll have better connection.
I see that channel 36 has twice the signal strength as channel 6.
I do see you are getting an IP address on your wlp8s0 connection.

To connect to a specific BSSID, use the following command:

sudo nmcli dev wifi connect network-ssid bssid BSSID

Replace network-ssid with the actual SSID and BSSID with the desired BSSID.

Use the following command to connect to a specific channel:

sudo nmcli dev wifi connect network-ssid channel CHANNEL

Replace network-ssid with the SSID and CHANNEL with the desired channel number.
