[Hardy] ipw2200: No Wireless Network after suspend resume

[Liken Otsoa]

After suspend to ram / resume, wireless network cannot establish connection. Although Interface eth1 is up.
This has only shown up after updates to Hardy in the last few weeks.
It requires a long time suspend/resume.

Trying to connect:

/etc/init.d/network restart
ifdown and ifup eth1
rmmod and modprobe ipw2200
Physically off and on laptop wireless.

All Fails. I need to reboot system.

System:
IBM Thinkpad X41 Tablet.
ipw2200 wireless module
Hardy Uptodate

Please attach the output of the dmesg command. Ideally attach one from immediately after a complete boot, and then a second from after you have suspended and resumed and wireless is no longer working.

[Liken Otsoa (liken)]

Well... This was finally related to same bug of _rename stuff.
Then I did the workaround rm /etc/udev/rules.d/70-persistent-net.rules,
but problem is not totally solved. After resume wireless network cannot connect.
I need to do a ifdown eth1 ifup eth1.
I attatch a fresh dmesg and dmesg inmediatelly after resume.

This may be a duplicate of Bug #183968, which was just marked as 'Fix Released'. Try upgrading to udev (117-6) and see if the problem persists.

[Liken Otsoa (liken)]

Problem persists.

After resume iwconfig shows this extrange result:
_____________________________________________

lo no wireless extensions.

eth1 no wireless extensions.

Normally eth0 is wired and eth1 is wireless. After resume eth1 is missing as wireless and there is a new interface eth0_rename.

it is done workaround: rm 70-persistent-net.rules

This problem persists.

These three above files are when system is OK. Before Suspend/Resume.

[Scott James Remnant (Canonical) (canonical-scott)]

Ok, could you attach the same three files from _after_ the resume?

Thanks

[Liken Otsoa (liken)]

After Resume, When network is down:

[Scott James Remnant (Canonical) (canonical-scott)]

Could you run "sudo udevmonitor -e > udev.log" and then suspend and resume your machine, leaving 30s between suspending and ressuming.

Attach the resulting log file to this bug

[Liken Otsoa (liken)]

First time:

udevmonitor -e > udev0.log

30 seconds. Network is OK at resume.

[Liken Otsoa (liken)]

Second time:

udevmonitor -e > udev.log

30 seconds. The problem appears. Network is Down at resume. iwconfig shows _rename stuff.

[Liken Otsoa (liken)]

Sorry. The first file would be this:

Liken: I'm curious, does Network Manager dispaly the eth0_rename as a wired connection?

I've always been able to get a connection without restarting through some combination of disabling networking via Network Manager and enabling, modprobe -r iwl3945 (and reload), and/or iwlist wlan0 scan.

Sometimes, if/when it finally reconnects, Network Manager displays it as a wired connection, which it most certainly is not. Disabling and re-enabling networking seems to correct the issue temporarily, and network manager displays the network as wireless.

[Liken Otsoa (liken)]

I use Wicd, not Network Manager, but this is not a high level bug, it is low level, udev or something.
I have tryed: modprobe -r ipw2200, network restart, ifup and ifdown all interfaces, and nothing.

[Liken Otsoa (liken)]

This bug persists. Frecuently after resume there is not network. And iwconfig shows eth0_rename as wireless, normally is eth1.

Also affects my Thinkpad T40, using a Cardbus wireless device (Broadcom) via ndiswrapper.

[Liken Otsoa (liken)]

For weeks I didn't get this bug, but after last updates (Kernel v18 included) to Hardy this days it is here again.

[Liken Otsoa (liken)]

This bug persists. After resume, frecuently an interface is eth_resume and no wireless without reboot.

[eqskcr (skullmug)]

This happens to me also

The problem happens 1 out of 2 suspends when my network is in "roaming" mode

If i set it to a manual connection I see the problem 1 out of 5-8 suspends

Once the connection goes i have to reboot

I have a Dell Inspiron 6000

Hey there,

I am no sure if the bug I am experiencing is this one, as it could also be <A href="https://launchpad.net/ubuntu/+source/network-manager/+bug/69892">bug 69892</A> or <A href="https://bugs.launchpad.net/ubuntu/+bug/69426">bug 68426</A>.

But in essence, I cannot reconnect to the internet through Network Manager after the system resumes from suspend or hibernation. It shows all the networks and I can try to connect to them, but even with both the lights green it won't eventually establish a connection.

I am running Xubuntu 8.10 on my IBM x41 and the problem first showed up when I upgraded from 8.04. I had issues with the Network Manager not being able to make a connection in the past, but I solved this by adding the following line to acpi-support:

# Add services to this list to stop them before suspend and restart them in
# the resume process.
STOP_SERVICES="networking"

However, this solution doesn't work in the current situation. And what is different, is that it still tries to establish a connection and almost succeeds in this, but it hangs after both lights turn green.

This could be bug #1052227, but I'm not sure.
