I recently tried installing Linux Mint Cinnamon 22.2 on a new machine, but I've been running into issues connecting to my Wifi network. It works for Bluetooth tethering, which helped me get updates, but I'm having no luck with Wifi. The network shows up, but I can't connect to it. I've tried using the terminal to connect, but it says the connection can't be found. Here are my specs: I'm using the MT7922 card with the mt7921e driver, and my Linux kernel version is 6.14.0-35-generic. Any suggestions?

Oh man, that driver has been a real pain for a lot of users. Some are even saying it's one of the worst supported chipsets on Linux. My best recommendation is to replace it with an Intel AX200 or AX210 module. They're pretty affordable and replacing them is usually straightforward if you're familiar with upgrading RAM or NVMe drives. Just make sure to check for interference or power management settings in your OS as well.
Here are some links that might help with your MT7922 driver issues. They contain information about firmware upgrades and troubleshooting: [Ask Ubuntu link](https://askubuntu.com/questions/1456981/ubuntu-22-10-mt7622-wireless-device-doesnt-work) and [Discourse page](https://discourse.ubuntu.com/t/firmware-upgrade-for-mediatek-mt7922-wifi-chip/56912).
Quick tip: it may be worth rebooting your router and checking for any power management settings in your OS that could be affecting your connection. If your system can see the card but can't connect, sometimes a simple reboot helps.
It sounds like you've run into some common issues with that driver. Many users have faced similar problems with the MT7922 chipset. While I can't provide a fix, here are a few alternatives you might consider: try a different distribution like Fedora; you can test Wifi without a full install. If that doesn't work, you could swap your Mediatek card for an Intel AX200 or AX210, which are known for better compatibility. Another option is to get a USB Wifi adapter that's Linux compatible, though that's definitely more of a hassle since it needs to stay plugged in.
Glad to hear you figured out the antenna issue! Sometimes the simplest things can trip us up. If others have similar problems, make sure to double-check that all components, especially antennas, are properly installed.
