can't associate with wifi access point after update

hello. i did an update yesterday(pacman -Syu) and after the update my wireless card can't associate with my access point. my wireless card is intel pro 2200bg, and my wifi is open without any encryption. i manually turn on wifi with the following commands:

ip link set wlp2s2 up
iwconfig wlp2s2 essid anyname mode managed channel 3
dhcpcd wlp2s2

any ideas?

Welcome to the forums.
If a kernel update was involved, you may just have to reboot.
If that does not help. post the output of

iwconfig 
ip a

after trying to connect, plus any errors you get from above commands.

Re: can't associate with wifi access point after update

Too bad. Does it scan for networks?
Also try to connect without further options

iw wlp2s2 connect anyname

. One way I like to troubleshoot is to open another session and let

journalctl -f

it follow the log.
