Description Konstantin Svist 2012-12-12 01:51:42 UTC
Description of problem:
If, while connected over wifi, ethernet connection is made, routing table is not properly updated

Version-Release number of selected component (if applicable):


How reproducible:
Every time


Steps to Reproduce:
1. Boot a laptop without ethernet, have it connected to a wifi network
2. Connect ethernet cable (same network)
3. Browse pages/check email/etc.
  
Actual results:
Wifi route is stuck as the default in the routing table, so network connection is not working right.


Expected results:
routing table should become exactly same as it would've been if laptop was booted up with wifi and ethernet enabled and plugged in, respectively.


Additional info:
Turning wifi off and then back on seems to work around the problem because the wifi interface gateway is removed when wifi is disabled. When re-added, wifi doesn't override ethernet gateway (correct behavior)

Comment 1 Jirka Klimes 2012-12-14 10:58:52 UTC
It works for me. 
What NM version do you use?

Make sure "Use this connection only for resources on its networks" is not checked in the editor (IPv4 Settings, Routes...).

Would you, please, collect more information for us?
1. your connections data
nmcli -f connection,ipv4 con l id "your ethernet connection name"
nmcli -f connection,ipv4 con l id "your Wi-Fi connection name"

'never-default' option should be 'no'.

2. /var/log/messages

Comment 3 Peter Oliver 2013-01-26 15:45:29 UTC
The issue seems to be that a metric is no-longer set for the routes:

Fedora 16:
$ ip route
default via 192.168.1.1 dev em1  proto static
192.168.1.0/24 dev em1  proto kernel  scope link  src 192.168.1.147  metric 1
192.168.1.0/24 dev wlan0  proto kernel  scope link  src 192.168.1.146  metric 9

Fedora 18 on the same hardware:
$ ip route
default via 192.168.1.1 dev em1  proto static 
192.168.1.0/24 dev wlan0  proto kernel  scope link  src 192.168.1.146 
192.168.1.0/24 dev em1  proto kernel  scope link  src 192.168.1.147

Comment 4 Fedora End Of Life 2013-07-03 22:05:16 UTC
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Konstantin Svist 2013-07-03 22:30:09 UTC
Issue is still present on Fedora 18 (all updates applied)
Didn't test F19 yet, but probably same thing

Comment 7 Peter Oliver 2013-12-21 17:09:42 UTC
Work for me in Fedora 19.

Comment 8 Konstantin Svist 2014-01-07 23:38:37 UTC
I'm in Fedora 20 now, pretty sure the bug is still present
Let me know if additional info is necessary

Comment 9 Fedora End Of Life 2014-02-05 23:18:21 UTC
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Comment 10 Konstantin Svist 2014-02-05 23:38:40 UTC
Present in F20

Comment 11 Thomas Haller 2014-02-06 10:43:51 UTC
This *was* a problem, got fixed and reappeared.

The original problem was fixed, for the regression please comment on bug 1050546 for F20, rawhide. Also see upstream bug at https://bugzilla.gnome.org/show_bug.cgi?id=723178
