[SOLVED] Wireless fails after suspending (Realtek 8192se)

This problem is already solved on the first post: I spent so long trying to solve it that I thought people should know the solution.
I have a Lenovo X100e with a Realtek 8192SE wireless card. I'm running kernel 3.0. The machine has, since upgrading to the 3.0 kernel had the annoying problem of failing wireless connections after suspending: I'll have a running wireless connection, then suspend the machine, and then wake the machine up and the machine cannot connect to any wireless network (perhaps the same one I was connected to before, in the same place).
Things that did not work:
Installing the Realtek drivers from their website
Downgrading the kernel from 3.1 to 3.0
Using wicd instead of networkmanager
Walking around
Other distributions
The solution was to put an entry in /etc/pm/config.d/config:
SUSPEND_MODULES="rtl8192se rtlwifi mac80211 cfg80211"
Now the machine reconnects with no problems.
This may be the solution to the other big problem I was having with the 3.1 kernel: I would suspend the machine by any means and the screen goes black and the machine becomes non-responsive without actually suspending. I may try upgrading to the 3.1 kernel and adding radeon to the SUSPEND_MODULES list above.

Found out more which might be significant for madwifi users:
According to the wiki I loaded the following modules in rc.conf: ath-hal, ath9k, wlan
Beside this one line in the modprobe.conf should be added: alias ath0 ath_pci. This way wicd as well as networkmanager used ath0 for connecting to wireless.
After the update I noticed that there is another wifi device in ifconfig listed: wlan0. So I suspected that 2 devices pointing at the same hardware may cause the instability, but de-activating one by ifconfig didn't help. Now I noticed by loading the modules one by one that the new ath9k is already defining wlan0 and the wireless starts working without loading the module wlan. It looks stable so far, but if I should be right I'm impossibly the only one having this trouble.
Confirmation would be nice, but I will mark this thread "solved" now.

[Solved] Atheros Wireless Fails after Update

After the update to kernel 3.6.37 the wireless on my Macbook pro is close to useless, but used to work very well before. Madwifi was upgraded as well but I suspect another problem.
Using WICD there is no wireless at all! With networkmanager the available networks are visible and sometimes logs on. However, the network fails quickly and starts asking for the password - most of the time it is useless typing in the password again. So the wireless is basically working but very unstable with networkmanager and non-existent anymore with WICD.
Any ideas?

I got mine working!
First I commented out the module parameter from my /etc/modprobe.d//intel-hda-audio.conf:
#options snd-hda-intel model=dell-eq
Since it works without that now, I will probably remove the file.
Next, I went into alsamixer, and noticed a couple items not there before, turned down low:
"Speaker", and two "HeadPhone" mixers, both turned down almost off. I turned up the volume on the speaker, and was able to get sound from the speakers. The same worked for the headphone entries (I have two headphone jacks).
After I did this, it works better than before because I used to only have one working headphone jack.
Also, I confirmed sound is still working after suspend/resume for me.
Hopefully this will help one of you.
Thanks,the problem has been resolved by downgrade.
Sound is absolutely normal before I suspend/resume my system, volume is normal, not too large,not too little. But there's no sound at all after resume it . I guess it's probably to have something to do with our audio card - HDA intel, my computer is also a dell laptop( dell 1420 , 2007/2008, really old ).
My advice is : don't upgrade to kernel 3.9.2 ,it's an odd version( odd version is not stable).

[SOLVED] Xfce4 Lock after suspend

Hello everyone,
I know that there was it already asked, but in my question is something different. Is there any option to lock screen with LightDM in Xfce4 when is system going to suspend ? I already edited /usr/bin/xflock4 and it locks screen when is executed from terminal or simply locked from xfce panel, but it doesn't lock screen when i suspend computer. In power manager and in session settings is option already ticked to lock the screen after suspend.
PS: I know that "dm-tool lock" doesn't really lock the screen only redirect you to tty2.
EDIT: Now it works so here is solution:
1. Install light-locker
pacman -S light-locker
2. Create systemd service
nano /etc/systemd/system/lock.service
[Unit]
Description=Lock X session
Before=suspend.target
[Service]
Type=oneshot
ExecStart=/usr/bin/xflock4
[Install]
WantedBy=suspend.target
3. Enable systemd service
systemctl enable lock
4. Add light-locker to xflock4 script
nano /usr/bin/xflock4
#!/bin/sh
light-locker-command -l

Unreliable wireless connection after suspend

I just did a fresh install of Arch on my netbook. I installed Openbox, tint2 and the network-manager-applet. All works fine, but when I run pm-suspend and then resume from suspend the wireless is dead >50% of the time (I cannot ping anything). Sometimes some websites work fine but others don't! If I reconnect to the wireless network manually everything is back to normal.
Any advice for a more reliable connection after suspend?
Thanks

I had a look but felt my issue wasn't identical. I've just found if I wait long enough (some minutes) it all works again (yet to confirm this is always the case).
EDIT
Switched to using wpa_supplicant and dhcpd and all works well
Couldn't see anything relevant in the logs

[SOLVED]No keyboard after suspend (xfce)

I have a problem similar but not identical to this: https://bbs.archlinux.org/viewtopic.php?id=155722
When I resume after suspending, the keyboard doesn't work. Unlike the cited thread, this only happens after suspend but happens either every time or nearly every time I resume after suspending. This is quite annoying because I prefer to suspend when the laptop is closed. The touchpad is also disabled after suspend, although I use a USB mouse anyway.
My specs (everything is up to date as of yesterday [1/15/15]):
Xfce on a Toshiba Satellite p55t-a5116 (specs here)
it's dual-partitioned (with Windows 8.1) as well, if that matters, and this install exists on a logical partition rather than a primary one.

I solved this on my own, so I'm posting the solution here in case anyone else has the same problem. Apparently xfce4-power-manager and systemd were both creating suspend events at the same time, causing problems loading modules like keyboard drivers upon resuming. The solution is in a small section of the wiki in the article on xfce, reproduced here:
Multiple suspend events
If using xfce4-power-manager to control ACPI events, and not systemd, edit /etc/systemd/logind.conf:
HandlePowerKey=ignore
HandleSuspendKey=ignore
HandleHibernateKey=ignore
HandleLidSwitch=ignore
After I did this, the problem disappeared.

Help with bash script that fails after suspend to RAM

I have a very simple reminder script that uses an endless loop, sleep and zenity to pop up a reminder every twenty minutes:
#!/bin/bash
while true;
do
sleep 20m
zenity --warning --title="Ergonomics Reminder" --text="Check Posture or Have a Stretch!"
done
However, it does not work as it should after suspending to RAM. I am thinking I need to kill the process and restart it after every suspend, using a "thaw" notice in /etc/pm but if there is an easier way to do it please let me know!

I'm doing this for 2 reasons:
- as a scripting exercise
- because the local repo is a shared wordpress mess and people forget to make commits so I'd like a local backup that includes all changes that may not be in github (sadly).
Anyhow, thanks for the input about trap, I'm definitely confused by it's use at this point but have reworked the script without it.
#!/bin/sh
set -e #Exit on any error.
TIME=`date +"%m.%d.%Y@%H:%M:%S"` # Define the TIME variable as today's date and time.
MONTH=`date +"%b"` # Define MONTH as today's month.
FILENAME="backup-$TIME.tar.gz" # Define the filename structure.
SRCDIR="/stuff" # Define folder to backup.
DESDIR="/Backup/$MONTH/" # Define the backup folder location.
LOGFILE="$DESDIR/backup-$TIME.log" # Store the output in a log.
REMOTE=$(git ls-remote -h origin master | awk '{print $1}') # Get commit hash from head of remote master repo (github)
LOCAL=$(git rev-parse HEAD) # Get commit hash from head of server repo (dev/test)
if [[ $LOCAL == $REMOTE ]]; then # If the hashes match
echo "No update required." >> $LOGFILE # Then no pull is needed
else # If the hashes don't match then prepare to run our backup
mkdir -p $DESDIR # Create our directory if it doesn't exist.
echo "Backup started for "$TIME >> $LOGFILE # Make it log what it's doing.
tar -cpzf $DESDIR/$FILENAME $SRCDIR >> $LOGFILE 2>&1 # Perform the backup.
echo "Backup Finished for "$TIME >> $LOGFILE # Log that it's finished.
echo "Preparing for git pull " >> $LOGFILE #Log what we're doing.
cd /stuff >> $LOGFILE 2>&1 # Make sure we're in our repo directory
git pull >> $LOGFILE 2>&1
echo "Git pull completed successfully. " >> $LOGFILE

Wireless fails after 1 minute

MSI Wind with rtl8187se (name of module and wireless hardware) and using wpa-psk. New installation of arch. Wireless works fine for 1-2 minutes then fails (can't get any response pinging google or pointing elinks to google, etc).
What I'm doing:
bash-4.0# ifconfig wlan0 up
bash-4.0# iwconfig wlan0 essid PrivateNetwork
bash-4.0# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
bash-4.0# dhcpcd wlan0
dhcpcd: version 5.0.6 starting
dhcpcd: wlan0: broadcasting for a lease
dhcpcd: wlan0: offered 192.168.2.2 from 192.168.2.1
dhcpcd: wlan0: acknowledged 192.168.2.2 from 192.168.2.1
dhcpcd: wlan0: checking for 192.168.2.2
dhcpcd: wlan0: leased 192.168.2.2 for infinity
dhcpcd: forking to background
If I pkill dhcpcd and start it again, still no connection.
If I kill dhcpcd, wpa_supplicant, and do "ifconfig wlan0 down", and start over, connection comes back for 1 minute & quits again.
I tried "iwconfig wlan0 rate 11M fixed" (to lower bit-rate from 54) but "fixed" seems not to work-- bit-rate creeps back up to 54 in 30 seconds.
And something weird with dhcpcd:
bash-4.0# dhcpcd -k
dhcpcd: dhcpcd not running
bash-4.0# dhcpcd wlan0
dhcpcd: dhcpcd already running on pid 2100 (/var/run/dhcpcd-wlan0.pid)
Please can someone help me understand what's going on? I've heard of problems with rtl8187se module but apparently its working for some people.

Thankyou, yes, I'm not even running a script yet, just running ifconfig/iwconfig/wpa_supplicant/dhcpcd on the command line. I've tried waiting a while before starting dhcpcd. Doesn't seem to make a difference.

S10e (4187XB5) wireless fails after a few seconds

The wireless thinks it is connected. It connects to the home (or office) wireless without trouble, acquires valid IP address, etc., but behaves as if unconnected after a few seconds.
I have tried:
Uninstalling and reinstalling the network adapter via Device Manager (after this, I can browse the web for a few seconds, then nothing will load again)
Installing all updates to the system (there were no significant pending updates)
Updating the driver for the Broadcom network adapter
Reverting to the earlier driver for the Broadcom network adapter
Updating the BIOS.
Firewall is disabled. Ethernet works without issues, but it is not practical to use the netbook on ethernet.
Assistance would be appreciated.
Solved!
Go to Solution.

Thank you for the suggestions. I do not have the Readycomm application. I did check the power management settings, and it was set to allow the computer to turn off the wireless to save power, so I unchecked and applied that. Still no luck.
I tried running the included PC Doctor 5 software and checking the network card. The Wireless Connectivity Test, Wireless Signal Strength Test and PCI Express Status Test all run without trouble. The TCP/IP Network Communication Test yields "Cannot Run," however. When I check the log, it says that the firewall may be blocking pings to the router, but the firewall is off. I double checked.
Edit: I am considering buying a replacement WiFi card, but I know this will only work if the problem is hardware. I'm still not sure; it seems counterintuitive that I it would be a hardware problem, since I can connect to wireless networks and browse the internet even for a few seconds. I can always see wireless networks and connect to them. It seems to be a TCP/IP problem.

Try downgrading wpa_supplicant. Sounds like a similar problem to this:

Wireless fails after pacman update

I had my wireless functional but after the latest set of updates it somehow broke.
It's a Broadcom wireless that uses the b43 driver.
I wrote myself a little cheater list when I first set up the wireless. The commands appear okay but when I attempt to get to the net I get a network unreachable error when I attempt to ping anything.
sudo ip link set wlan0 up
sudo iwlist wlan0 scan | grep ESSID
I see the available wireless. 2WIRE824 is my router.
ESSID:"2WIRE824"
ESSID:"Enforcer24GHz"
ESSID:"2WIRE409"
ESSID:"2WIRE907"
ESSID:"BAMFs"
I submit my key and attempt to connect to my router
sudo iwconfig wlan0 essid "2WIRE824" key **mykey**
sudo dhcpcd wlan0
returns --> dhcpcd[797]: sending commands to master dhcpcd process
now when I try to ping anything I get network unreachable.
What has changed (or what am I missing) that broke the wireless?
I have all my wireless profiles that haven't changed and they are still listed in /etc/rc.conf
I've even tried
sudo iwconfig wlan0 channel auto
despite my cheatsheet stating to use that only if the dhcpcd times out.

I feel like the above output has something to do with it. Is wlan0 still down? Why didn't it go up? And why no error message that it didn't successfully go up?

Any thoughts/ideas/ or add'l info to help debug?
Thanks!

I had asked about systemd because I have noticed it sometimes starts things that have been installed and are lying around dormant if they were not in the DAEMONS array. I have been bitten...
So, you said...

I would like to see the output of a second iwconfig without any switches or parameters performed a few seconds after that first one, just as you wrote it. I want to establish if you are actually associating with the AP. You should see the MAC of the AP in that output.
Then, you said
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:ff:ff:ff:8b:78 brd ff:ff:ff:ff:ff:ff

link/ether 00:14:a5:0d:64:e5 brd ff:ff:ff:ff:ff:ff
Okay, the wlan has no address, as expected. The carrier, however should be up.
[arch-nicky@arch-nicky ~]$ ip link set wlan0 up
RTNETLINK answers: Operation not permitted
But you have to run that as root
So, put the interface up as root.
Try to associate with sudo iwconfig wlan0 essid "2WIRE824" key **mykey**
Pause. Run iwconfig
If it associates, then run dhcpcd wlan0 . Don't waste your time if it does not associate.
If you are still having trouble, look at the output of rfkill list
One last thought. Are you trying to connect to the same router as you are wired to? You should be able to associate, but you may have routing issues later.

[SOLVED] X dies after suspend+resume, dropping me into LXDM

If I do a sudo systemctl suspend and then resume, the computer comes back to life with LXDM, suggesting to me that it failed to bring up X properly and everything in that session died with it.
I'm not quite sure where to start looking with this one, any ideas?
Last edited by linduxed (2015-04-12 12:58:46)

I waited a couple of days, tried suspending again and now things work as they should, or at least they appear to.
I have no idea what has changed.

[solved] boot fails after recent update

After updating a load of packages today my system fails to boot with the following message:
Checking Filesystems [Fail]
********************Reboot Required*********************
* The System will be rebooted automatically in 15 seconds *
Then it just reboots. I can't get past this message.
I did not upgrade the kernel26-firmware package since I run kernel26-ice 2.6.29.
I can't find any logfiles for hints. What could be wrong?
[Edit 2009-07-06]
I checked the filesystems from a rescue system to no avail.
Last edited by mykey (2009-07-07 09:54:15)

Oh well - took me a while to figure things out this time maybe the solution helps somebody else.
Since I use reiser4 as a filesystem I had to recompile reiser4progs against the new libreadline in order to allow a proper fsck during boot

Wireless fails after Lenovo driver update (X40 23718EU; Atheros 11b/g Mini PCI)

I use Windows XP SP2. My wireless LAN adaptor driver was old (ver 3.1.102.23) and did not support WPA2 protocol so I updated it from the Lenovo site using this driver download: Windows XP, 2000 06 Oct 2009 v7.6.1.260b
Immediately afterward on IBM Access Connections screen, the "Enable wireless radio" menu item no longer would turn the radio on. (I did manage to turn the radio on using Device Manager properties Advanced tab Radio On/Off setting.) Also on that screen, I could no longer see any wireless networks in the "Find wireless networks" button.
So, before I do more damage, any thoughts? Some questions occur to me, not sure if any of them is useful?
1. Since I went directly to Lenovo to download the driver, is the Windows driver Rollback feature likely to work or just to make things worse? (I never heard of Rollback before today.)
2. I could find no good help poking around Lenovo documentation. Atheros seems even less helpful.
3. Has anyone successfully installed a driver lately on Thinkpad X series for this Atheros WLAN adaptor for Win XP?
4. Although I think it's a waste of time, I did try the Windows setup a wireless network wizard for the device. No luck there yet, either.
Have to reboot now, will update if anything new shows up afterward...

Thank you so much for this posting! I had the same problem until I followed your instructions.
The radio is still listed as being "off" on the "show status window", but hey, I'm connected to my wireless network with a wpa-psk password, I can access the internet and use the printer, so all is well. Or will be when I get System Manager to work right - how many hours does a virus scan take, anyway?
Hi and welcome to the forum!
The radio should say "off", but the status should say "on". The button is just like electricity's switch, "Radio off" literally means to turn off device.
As for virus scan, it depends on which one you're using and the amount of data your drive contains.
Hope this helps.

[SOLVED] X fails after pacman -Syu

After a year or so without upgrading (not recommended) I did a pacman -Syu; it took like ages 'cause I was on kernel 2.26, and now my arch is a complete mess: user modules don't load at boot, dhcpcd is not working so I don't have internet access and the X server is erratic too. Now I have to repair it step by step, and I think I should start with X.
Here is the startx/ xinit output:

I guess the gnome-session error with libdevkit-powe-gobject.so.1 is what causes the x server to close. And this is the complete X log:

So you updated everything except gnome-stuff? Update the gnome-stuff.
But I'm all for gnome 2 , and X should work despite of the gnome version or the desktop environment. Shouldn't it?
No, not if you're using gdm or autoboot into gnome or something similar.
gnome-session: error while loading shared libraries: libdevkit-power-gobject.so.1: cannot open shared object file: No such file

This sounds like one of gnome-sessions dependencies have been updated and isn't compatible with gnome-session anymore.
