dhcp problems after upgrade for wlan0

Hi there.

After upgrade of the system I am not able to connect to my android wifi hotspot. These are the logs I get from systemctl and jorunalctl:

 systemctl status netctl@s1.service

Also I tried to downgrade dhcpcp and netcl but the problem is still here:

[2014-07-21 18:49] [PACMAN] Running 'pacman -U dhcpcd-6.3.2-1-x86_64.pkg.tar.xz'
[2014-07-21 18:49] [PACMAN] downgraded dhcpcd (6.4.0-1 -> 6.3.2-1)
[2014-07-21 19:00] [PACMAN] Running 'pacman -U netctl-1.7-1-any.pkg.tar.xz'
[2014-07-21 19:00] [PACMAN] downgraded netctl (1.8-1 -> 1.7-1)

Complete log file can be found here: http://sprunge.us/ZKPf

I then tried to manually connect to with wpa_supplicant but I got failed to open error:

sudo wpa_supplicant -B -i wlan0 -D nl80211 -c <(wpa_passphrase s1 hidden123pass)
Successfully initialized wpa_supplicant
Failed to open config file '/dev/fd/63', error: No such file or directory
Failed to read or parse configuration '/dev/fd/63'.

Any help would be appreciated.

Note: dhcpcd works if I try to connect with usb0

Re: dhcp problems after upgrade for wlan0

Re: dhcp problems after upgrade for wlan0

Okay, thanks.  I was making sure that network names did not change on you.  Are we sure that the wireless is associating with the access point?   Can you post your service file?

Re: dhcp problems after upgrade for wlan0

Thank you for your help ewaller.

I'm not quite sure if Wireless is associating with AP as AP is in my case android phone:
- When I try to connect with wifi-menu I see my AP and I select it and then try to connect. I tried to look at /data/misc/dhcp/dnsmasq.leases to see if connection is made with android phone but obviously this file only shows connection that were successfully made in last n minutes/seconds?

If by service file you mean netcl file then this is it:

Description='Automatically generated profile by wifi-menu'
Interface=wlan0
Connection=wireless
Security=wpa
ESSID=s1
IP=dhcp
Key=hidden123pass

Re: dhcp problems after upgrade for wlan0

Any chance that anything has changed on the phone?
The next step would be to try it by hand.  That would mean using wpa_supplicant to connect to the phone and to see if you can associate with the phone.  Then, after associating, we can try to obtain an address.

Re: dhcp problems after upgrade for wlan0

Nothing changed on the phone. I tried with 2 different android phones.

I tried by hand as statedn in the first step:

sudo wpa_supplicant -B -i wlan0 -D nl80211 -c <(wpa_passphrase s1 hidden123pass)

But I get following:

Successfully initialized wpa_supplicant
Failed to open config file '/dev/fd/63', error: No such file or directory
Failed to read or parse configuration '/dev/fd/63'.
