Удалось добиться следующего:
wlan0 IEEE 802.11g ESSID:"dlink"
Mode:Managed Frequency:2.437 GHz Access Point: 00:1E:58:81:C2:C1
Tx-Power=15 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Encryption key:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

dhcpcd выдаёт:
err, wlan0: timed out
warn, wlan0: using IPV4LL address 169.254.53.192

Если вручную ставить 192.168.0.2 или 192.168.0.100, то ping до т.д. не проходит:
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
From 192.168.0.100: icmp_seq=1 Destination Host Unreachable
From 192.168.0.100 icmp_seq=1 Destination Host Unreachable
From 192.168.0.100 icmp_seq=2 Destination Host Unreachable
From 192.168.0.100 icmp_seq=3 Destination Host Unreachable

Дальнейшие действия?
