wlan0: invalid UDP packet from 10.0.0.1

Okay...
After installing the b43 driver and firmware (I think), I cannot get dhcp to work.

This used to work sporadically with the wl driver, but that was really unacceptable behavior. 

# lspci -vnn |grep 14e4
0b:00.0 Network controller [0280]: Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 05)

So, I found a table on the broadcom page that said I could use the b43 driver. So I went ahead  and installed it, blacklisted the b43-legacy driver and the wl driver, and rebooted. b43 won't start on boot and I have to manually load it. I don't really care about that though.

Once the b43 driver is loaded, I can run the wpa_supplicant in the background from a configuration that I know worked in the past. After that, dhcpcd returns this:

[root@myhost rules.d]# dhcpcd wlan0
dhcpcd[2206]: open_control: Connection refused
dhcpcd[2206]: version 5.2.12 starting
dhcpcd[2206]: wlan0: broadcasting for a lease

dhcpcd[2206]: wlan0: invalid UDP packet from 10.0.0.1
dhcpcd[2206]: timed out
[root@myhost rules.d]#

or dhclient -v wlan0:

[root@myhost rules.d]# dhclient -v wlan0

I have no idea what else to do. Static IP is not an option in my situation, not that it works anyways. The wired connection does not exhibit these issues.

Re: wlan0: invalid UDP packet from 10.0.0.1

Before issueing the dhcp, is your card associated to the correct wifi-router?  (check with iwconfig)
If yes, how do you call wpa_supplicant?
Also if you have access to the router, you might want to test the connection by turning off encryption first and see if it works then.

EDIT: Another suggestion in the wiki https://wiki.archlinux.org/index.php/WP … HCP_Server
