{SOLVED]Updated system now Wi-Fi adapter won't turn on?

Hello,
I upgraded my system last night. But now my Wi-Fi adapter won't turn on at all. NetworkManager isn't even seeing the adapter. I think it might have to due systemd or maybe the drivers I got from the AUR are broken. I was wondering if any of you guys know what might be going on. My laptop is a Gateway LT2030u.
Thanks,
Jonathan

I am not really an advanced user, but I do have a little experience with wifi issues, and I am currently running the TP-LINK TL-WN821N USB without issues.

First, probably would help if you noted what adaptor chipset you have. Also is this internal or external? Probably internal...

You said you updated last night. I am curious when your previous update was? Were there any unusual messages during your update?

Next, did you check dmesg to see any info about card recognition? I also grep through the journalctl output.

Then, I would check the wiki https://wiki.archlinux.org/index.php/Wifi and follow the manual setup steps there, so you can get more of a hint as to  what is causing your problem. From a prior life, I believe the utility rfkill helped with wifi internal adaptors.

For me, I run a simple set of scripts, for open and encrypted wifi access points. I don't use any netcfg or networkmanager type automation tools. My scripts work well for me under systemd. I don't use any AUR stuff. Mostly, I think the Atheros chipsets work well.

Hope this helps and have a good day.
Steve.

Internal sound card. My last update was about a month ago.  Nothing unusual happened during update. I see a message about loading a module for my adapter when I boot up but it goes to fast for me to read. rfkill shows that the soft-block turns on and off if i flick the switch back and forth.

OK. start up screen says it's missing the b43 fireware. I'll try installing that and seeing if that makes a difference.

Without ethernet cable plugged in: [jon@localhost ~]$ ip link

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT qlen 1000
    link/ether 00:26:22:6f:57:2d brd ff:ff:ff:ff:ff:ff

Fixed it. I was missing the b43-firmware from AUR. Installed it with yaourt and it worked fine.
