wifi fails to connect - no DHCP4 address
Sep 17th 2012, 08:49

This is a continuation of thread http://forums.opensuse.org/english/g...ml#post2486770 The original problem appears to be solved in that dmesg shows that association and authentication now holds. ifstatus wlan0 also shows this to be the case:

wlan0 name: 802.11n WLAN Adapter
DHCP4 client (dhcpcd) is running
. . . but is still waiting for data
DHCP6 client (dhclient6) is running
. . . but is still waiting for data
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
link/ether 00:1f:1f:e4:4f:66 brd ff:ff:ff:ff:ff:ff
inet6 fe80::21f:1fff:fee4:4f66/64 scope link

wlan0 is up
bssid=00:81:d8:42:1e:9a
ssid=BTHub3-TZM5
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=TKIP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED

However, there is still no internet connection and ifconfig wlan0 produces:

wlan0 Link encap:Ethernet HWaddr 00:1F:1F:E4:4F:66
inet6 addr: fe80::21f:1fff:fee4:4f66/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:34 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:306 (306.0 b) TX bytes:8986 (8.7 Kb)

As I understand it, there should be a line inet addr:, which indicates to me that DHCP has not done what I expected it to although there is an inet6 addr: line. As far as I can see from YAST there is nothing wrong with my DHCP settings. I may be barking up the wrong tree - can anyone help? Are there other tests/commands I should run to shed light on this?
