I recently upgraded my HP DV7 to 11.2.
I did the install with wired network connection, my WiFi is always on as well.
Install went fine, ran updates via YAST.
I am running KNetworkManager, it loadeded, configured eth0 and wlan0, prompted me for WEP keys and showed both connections working OK.
I later found that when eth0 was disconnected, wlan0 was still connected but I could not reach internet sites. My router address was set as the gateway address and the DNS server address.
Following several items on the forum, I tried ‘dig’ and ‘route’ commands.
I found that
HPDV7-Linux:/etc # dig www.comcast.com
; <<>> DiG 9.6.1-P3 <<>> www.comcast.com

returned a valid URL for that server - DNS seemed to me working properly via my router.
I found that
route
returned:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.10.0 * 255.255.255.0 U 2 0 0 wlan0
loopback * 255.0.0.0 U 0 0 0 lo
Hmmm, no default route showing.
I then opened the Network Manager connection editor, went to edit for the wireless connection and found under the IP_Address tab, Routes option box that both
Ignore automatically obtained routes
and
Use only for resources on this connection
were enabled, I believe by the install process. Unchecking these yielded
HPDV7-Linux:/etc # route

and internet connectivity now working.
