It appears, the for me, NetworkManager is not working correctly,
so I used network instead.  I am able to get access to all local lans
and FireFox works only for local connections - not for Internet
(outside) connections. I found a real quirk with the network tool,
it messes up the settings badly, like placing Default router into
Netmask.  Very odd, so I had to edit /etc/sysconfig/network-scripts/ifcfg-*
(and checked Networking) and manually enter the correct values.  I have
had to do this before in F8 and in F9.  Seems like a reoccurring theme.

Clearly, I am unable to get the F10 to reach the default router
(or so it seems), so I checked the routing tables:

# route
Kernel IP routing table
Destination     Gateway         Genmask          Flags  Metric   Ref    
Use   Iface
10.1.0.0                *                255.255.255.0   U          
0           0        0      eth0
link-local             *                255.255.0.0       U          
0           0        0      eth0
default               sonic            0.0.0.0               UG       
0           0        0      eth0

Which matches my F9 routing tables.

I cannot figure out why I cannot reach the Internet (default router)
as I am able to access the entire local LAN system...  What am I
missing here?

       Update: Samba was blocked by Firewall by default.  Checking
       Samba in Firewall tool enables the Places->Network to appear.
