Freshly installed, ip link does not detect wlan0

I had no issues to connecting to wifi when working from the archiso, but now when I reboot and log into the new system ip link does not list wlan0 as it did before. I have no idea what packages I might be missing.

Re: Freshly installed, ip link does not detect wlan0

Did you install the linux-firmware package?
If so then please post the outputs of lsusb and lspci.


No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: Freshly installed, ip link does not detect wlan0

Are you having the same problem as the person in this post here?

If so, I'm guessing you need to have the brcm80211 package installed but not broadcom-wl. See Broadcom Wireless in the wiki.
