Wireless Link is Dormant [Solved]

I am having problems with my wireless link, because it continuously switches to mode Dormant.

# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 2c:60:0c:0e:6e:89 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 10:08:b1:57:35:61 brd ff:ff:ff:ff:ff:ff

When I try to connect to an access point it seems to connect without a problem:

# iwconfig
enp3s0    no wireless extensions.

wlp2s0    IEEE 802.11abgn  ESSID:"Lantech" 
          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:E0:20:22:67:2C   
          Bit Rate=26 Mb/s   Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=64/70  Signal level=-46 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:4   Missed beacon:0

lo        no wireless extensions.

but, I presume because the mode is DORMANT, the connection is not recognised, so I am not actually on the network.

The hardware is

product: AR9462 Wireless Network Adapter [168C:34]
vendor: Qualcomm Atheros [168C][
using
driver: ath9k
driverversion: 4.5.1-1-ARCH

Arch has been updated today.

Any help would be very much appreciated.

PS When I was googling the problem I found this which I tried without success

# ip link set wlp2s0 up
# wifi-menu
# dhcpcd wlp2s0
# iw wlp2s0 link

but wifi-menu returns an error:

Re: Wireless Link is Dormant [Solved]

So it seems that the problem had nothing to do with the DORMANT/DEFAULT issue after all. It was the DHCP server on the router which has stopped working correctly.

I would still be interested in understanding the difference between the modes DORMANT and DEFAULT, if anyone knows?
