Red Hat Bugzilla – Bug 150293
Same static IP network on both wired and wireless prevents routing on wireless.
Last modified: 2008-02-06 19:23:27 EST
Description of problem:
When both wired and wireless networks have static IP, and both IP
networks are the same number, and wired is not connected, system
attempts to route all gateway traffic via the wired adapter (eth0). If
wired adapter is down (ifdown eth0) then no external networks are
reachable -- the wireless connection is then useless except for local
traffic, even though the static IP config for the wireless adapter
clearly shows the default gateway listed correctly.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Starting with a fresh FC3 install on a laptop with centrino
wireless, configure the wired network card eth0 with a static IP
address, DNS, and gateway.
2. Verify connection to internet on wired interface (download wireless
drivers/firmware if needed). Then disconnect the wire and reboot.
3. Then install wireless centrino drivers and configure that interface
(eth1) as a static address on the same network (e.g. if the IP for
eth0 was 192.168.1.3/24 then make this one 192.168.1.4/24). Enter the
same gateway and DNS info as for the wired interface. Activate eth1,
reboot if necessary.
4. At this point you will not be able to ping the router unless eth0
is down. Entering ifdown eth0 and then a ping will respond, but now
there is no route to other networks.
Actual results: Can connect to all local systems, no routing through
Expected results: Expected normal routing.
Additional info: Type "route" in a terminal and you will see there is
no route to other networks.
