[SOLVED] I dont know how to install the broadcom driver

Hi, recently i damaged grub so now im cant boot into arch, so i reinstalled arch linux because i dont know how to reinstall grub. Reinstalling the system means that i would have to reinstall all the programs that i use, the problem is that when i first-time installed arch linux in my pc almost all the drivers installed automatically except for the Broadcom one, i dont use ethernet so im forced to use wifi but i cant connect to any wireless network because the wlan0 device is not showing, because the kernel driver is not installed that is what i think. But in the archiso (Live CD) wlan0 shows in iwctl and when i use $ lspci -k or -u? I forget that, the kernel driver for my broadcom pci shows as "wl" but that not the case when i boot from installed arch in my hdd. I alredy installed broadcom-wl package but nothing happens .

Sorry for any gramatical errors or any bad spelling.

PD: I just installed the latest broadcom-wl package on the AUR, but really i dont know what i did but it works now!

I think you want broadcom-wl 6.30.223.271-716. 700 is not going to match that system's running kernel.

And what that means?

The current broadcom-wl broadcom-wl 6.30.223.271-716 where the 716 is the package release number while the output you posted showed package release 700,  sixteen releases out of date meaning it was built for a much older kernel and that is why your system's running kernel will not load it.

Note that partial upgrades are not supported you are using Arch incorrectly if you don't do full system updates and there might be much worse potential fallout if you routinely operate updates this way.
