First of all, I'm new to Fedora and Linux generally. So, I can only provide you with iwconfig log because I don't know what else I should post. If needed, tell me please which logs should I post and I'll do it.

I've been using Mint for about a week and had problems with my WiFi connection so I switched to Fedora just to find out it hasn't changed and I have the same problem on Fedora.

Now to the problem: I'm connected to WiFi, everything works just fine and after some time (few minutes to several hours, randomly) sites stop loading and ping command says "Name or service not known" but network manager says I'm still connected. After disconnecting and connecting again it works normally (till it happens again).

P.S.: I'm running dualboot. Never had any problem with WiFi on windows.

Thank you.

Did you examine your logs? Any errors from journalctl --unit=NetworkManager? Maybe journalctl -u wpa_supplicant. Check for known issues with your wifi adapter and respective kernel module -- look at the output of lspci -k and dmesg for clues. You might need additional firmware, do a dnf search firmware and look for your wifi chipset. Is it installed and up to date?

Ok, so I checked my logs and there was no error to find.

BUT, I looked up which wifi adapter am I using and found out that it is rtl8723be . I checked for known issues and found this thread on ubuntu forums:

That problem looked pretty similar to that one I've been experiencing. So I executed the following command and everything works fine now.

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

Well, look at you. All new to Linux and you figure out your own problems with a little time. You’re gonna be an expert in no time at all. Prepare to add “troubleshooting”, “problemsolving”, and “Linux” to your resumé.
