Public bug reported:
Binary package hint: network-manager
I have a U.S.Robotics ADSL router here, with both wired and wireless
connection to my laptop. They both work when booted with the cable
plugged in, nm applet shows both, route -n shows:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
It seems that the wired connection is actually used to transmit packets.
When I unplug the cable, the wireless connection is used.
When I plug the cable again, the network is put in a weird state: some
connections succeed, some do not. A typical ping loses the first 5–7
packets but all the following ones return; sometimes the first packet
returns and all the following ones do not, or none return. route -n is
very similar, only the first two entries are swapped. DNS does not work;
/etc/resolv.conf contains:
# Generated by NetworkManager
nameserver 192.168.1.1
nameserver 192.168.1.1
while normally the router IP is listed only once. The nm applet has the
same display in either case, with both wired and wireless connection up.
Clicking on the wireless connection to reconnect it brings the state
back to normal where everything works. Clicking on the wired connection
does the opposite: it changes the state from working to the anomalous
one. So it seems that the bad thing happens when the wired connection is
getting enabled while the wireless connection was up.
This is network-manager
