Network disabled after resuming from suspend (not a driver issue)

[danmarycap]

What's working for me currently involved three changes. I'm not sure what the minimal set of changes is, but it works.

1. /etc/pm/config.d/00sleep_module

SUSPEND_MODULES="ath_pci"

2. /etc/pm/config.d/local

SUSPEND_MODULES="ath_pci"

3. a resume script:

# 2009-03-01: below are some things I tried that helped somehow
sudo /etc/init.d/networking restart
sudo modprobe wlan_scan_sta
sudo ifconfig eth0 down
sudo modprobe ath_pci

A very similar fix worked for me:

1) sudo gedit /etc/pm/config.d/00sleep_module

added this text as the last line in the file and saved:

SUSPEND_MODULES="wl0"
(note: it's a Dell mini9 with a Broadcom 43xx wireless adapter)

2) sudo gedit /etc/pm/config.d/bcmwifi
(note: this file does not exist, but I created it)

added same text (SUSPEND_MODULES="wl0") as only entry in this file and saved.

Now when I resume from suspend, I don't need to go to terminal to issue any commands...if my wireless was connected before suspend, it automatically reconnects afterwards.

Thanks to gib2800 at this post (http://ubuntuforums.org/showthread.p...resume+network) as well as a few other posts where these solutions are suggested. I don't know which of these actions (or both?) did the trick, but it works.

I have an Edimax 7318usg wireless card, with a ralink chipset and rt73 driver.
I`m new to Linux. What would I need to do to get mine working after suspend?
Thanx in advance.

The same fix worked for me on my Dell Optiplex gx620.

I only needed the first step, as outlined here:

I had the same problem with my Intel PRO/Wireless 2200BG card. In order to turn the wireless radio on after a boot I have to run a script:

#!/bin/bash
sudo modprobe fsam7400 radio=1
exit

I finally figured out what was needed to keep my wireless going after a suspend -- just unload and reload the driver fsam7400 via modprobe after resuming from a suspend:

#!/bin/bash
sudo modprobe -r fsam7400
sudo modprobe fsam7400 radio=1
exit

This seems to work well for this particular driver.

Cheers!

actually, it seems to be sufficient to simply use

#!/bin/bash
sudo modprobe -r fsam7400
sudo modprobe fsam7400 radio=1
exit

for a wireless-load script, irrespective if after booting or resuming suspend.

Is there any feature request on the bug tracking for this workaround?
