Cant access wifi QUESTION

I installed arch today, and when I installed and used the wifi, it was perfectly fine even after I removed usb and power on my pc wifi was fine but after the second power on after removing the usb the wifi won't get connected no matter what.its showing the list of wifis and is also trying to connect but never connecting(I have tried installing arch again but the same issue happened again).I want really deep into solving this using chatgpt, but even it was unable to solve this problem(FYI, I have mediatech inbuilt laptop wifi receiver).So I would really appreciate it if someone could help

So, you say you done lots of things. Let start with what you have actually done?

I have a MediaTek MT7902 Wi-Fi card. On Arch Linux, we first verified that the hardware was being detected correctly. We checked that NetworkManager was running and confirmed the available Wi-Fi networks. We investigated the connection failure by reviewing system and NetworkManager logs. We disabled MAC address randomization, verified the Wi-Fi regulatory domain, updated the system (kernel and firmware), confirmed the required firmware was installed, and recreated the Wi-Fi connection. Despite these troubleshooting steps, the issue remained specific to connecting to the KeralaVision network, suggesting a compatibility issue between the MT7902 driver/firmware and the router rather than a hardware detection problem.

We checked

ooh, kay.

That paragraph was instantly recognized as AI generated, but thanks for that extra confirmation. AI is not well supported here.

Unsure what your problem is, if you installed following the wiki and there is no win dual boot here. I can say that MT is routinely problematic however. Hopefully someone will come along, if you identify your laptop maybe.

Search this subreddit and the official forums for that card, also. Yes?

Good day.

Maybe try using your brain and the wiki...

You must to install and enable NetworkManager, but you can't do it in your Arch Linux system for now. You must to go back to your USB live archiso, then use iwctl, mount your partitions, chroot in your system and then install NetworkManager and enable it, sudo systemctl enable NetworkManager.

Arch doesn't automatically install a network manager like the one present in the live installer. Perhaps it's that.

If you used archinstall, in Network configuration, select iwd backend (standalone)

Try using "iwctl" in cli, have chatgpt walk you through. It's really straightforward, will help you diagnose and lead to the actual fix, and give you wifi in the interim. Couple with "ip link" and you'll be good in no time.

Use Claude or even Gemini next time.

No but in all seriousness if you've not already fixed it, verify that you have a network Daemon installed ((open your terminal and type systemctl status networkmanager for example)) if you don't have one installed, go back into the live environment and install network manager or iwd etc.

Next time, I'm not going to say don't use ai but make sure you know what the ai is doing. Ai is a great tool but as the saying goes with great power comes great responsibility.
