Issues with DHCP on install media with wifi-menu on 6/1/2016 iso

I have a work around for this but I'm reporting this now for visibility and to help others who may come across this issue.

EDIT: After several more attempts it looks like there is a chance it will connect, but more often it will not.  There is also a known issue with 5G crashing firmware for this particular card that appears to have been fixed in the most recent Arch from pacman.  I did still get this crash on the install media for 6/1/2016.

My network interfaces:

lspci -nnk | grep -iA2 net
3c:00.0 Ethernet controller [0200]: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] (rev 10)
	Subsystem: Micro-Star International Co., Ltd. [MSI] Device [1462:1155]
	Kernel driver in use: alx
--
3d:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 20)
	Subsystem: Bigfoot Networks, Inc. Killer N1525 Wireless-AC [1a56:1525]
	Kernel driver in use: ath10k_pci
	Kernel modules: ath10k_pci

firmware:

dmesg | grep firmware
ath10k_pci 0000:3d:00.0: firmware ver SW_RM.1.1.1-00157-QCARMSWPZ-1 api 5 features ignore-otp,no-4addr-pad crc32 10bf8e08

I noticed in the previous month's iso (archlinux-2016.05.01-dual.iso) I was able to use wifi-menu from the install media just fine but this month's (archlinux-2016.06.01-dual.iso) version fails to connect without intervention.  (it is also interesting to note that in both the previous month's and this month's the installed arch would also fail and require the dhcp configuration).  NOTE: for those of you interested in why I am installing again this month on a rolling release distro, it is because I am testing the install process on my MSI GS40 so I can write up a tutorial on getting it (mostly) working with Arch.

The error is simply "CONNECTING FAILED" in the wifi-menu UI but when you run systemctl status on the failed interface:

systemctl status "netctl@wlp61s0\\x2dMY_WIRELESS_NETWORK.service"

I get a little more information such as the following:

...
archiso dhcpcd[1025]: timed out
archiso network[808]: DHCP IPv4 lease attempt failed on interface 'wlp61s0'
archiso network[808]: Failed to bring the network up for profile 'wlp61s0-MY_WIRELESS_NETWORK'
...

In order to get this working I have to configure the wireless profiles manually in /etc/netctl.  I basically generate the profile with wifi-menu by allowing it to save the profile even when there is an error.  Then I add the following two lines:

ForceConnect=yes
DHCPClient="dhclient"

When I install I also need to make sure and download the dhclient package as this is already available on the install media but not in the installed system:

pacman -S dhclient

If anyone who is more familiar with what exactly is going on here would like to comment I would be curious to know why.
