Wireless not working after reboot

I am new to Arch. I recently installed it on my system and everything was working find until I rebooted. My wireless driver just seemed to have stopped working, yet it can detect the networks in my area. I just can not connect to them.
When I use an external wireless card I can connect just fine though.
I have done a lot of research, looked at a lot of posts, but I can not figure out how to fix this problem. It makes no sense.
I tried using wicd, and like everything else it picks up the network but I can not connect to it.
Here is the output of
ip link
Not sure if it is of any help or not, but meh...

Welcome to the Arch forums max00355!
So you are having wireless issues. Typically when you find you have a problem with a particular piece of hardware, it is probably good to take a look at what kind of hardware you have and provide that information. In this case, it sounds like it is your internal wireless card, so presumably a pci device. So you should use the command below to find information about what kind of card you have.
$ lspci -vnn
Ideally, it would be good if you didn't post the whole output, as there is a lot of irrelevant info there. So just paste the part that relates to your wireless card.
Then, it also would probably help if you provided some detailed information about the network to which you are trying to connect. We don't need your ESSID or passkey or anything. But it is probably important to at least give an indication of what type of security is at play here (ie. wep, wpa2, etc.).
Also, when you have wireless issues, it is often very good to go back to the most basic of tools to see if you can get those working. Then you can at least get an idea of either what step is going wrong, or if it might happen to be an issue with the network management tool you are using. So see if you can get wpa_supplicant/wpa_passphrase and dhcpcd working (or iw/iwconfig instead of wpa_supplicant if you are using wep).
Finally, I would like to commend your use of code tags. That is certainly very impressive for a brand new forum member!

Wireless not working after VMware kit installation

After installing VMWare kit, my wireless network card is not working - any clues?

there is something very wierd here. Let me recap what I KNOW is happening.
1) I can connect to WAP at boot no problem. This is true 100%
2) After sleep systems fails 100% time from 5:30 AM to 10:00PM (not sure why)
3) There have been no changes to WAP (confirmed using checksums)
4) This started immediately after 10.4.10 install.
What I have done that does NOT work
1) Repair disk perms (no errors)
2) Repair keychain (no errors)
3) Remove Parallels (expired Demo)
4) Remove/recreate network
5) Run commands indicated in other replies
What I have done that showed hope
1) If I create a new location I can use that location to recover from exactly 1 sleep. Subsequent sleeps fail for that location. once all locations are used a reboot is required.
2) Issued ipconfig setverbose 1 and watched logs. It seems that the Mac never Sees the incoming packets. I can rule out WAP issues as the Dell d620 sitting right next to the Mac is indicating packet reception at 100% (and I am only 10ft from WAP with direct line of sight).
3) issued ipconfig getpacket en1 in both working and non-working states. Woring stated returns expecte DHCP response from server. non-working state returns nothing. as in not even a blank line.
So as I see it the Mac does not appear to be reenabling the reciever post sleep. Changing locations seems to re-init the airport card but only once (why once?) enough to get it working. What I don't understand is where in software land I would even start to look. I find it hard to believe that there is a coincidental sync between an OS update and a hardware failure on a 4 week old machine.

[SOLVED] Printer not working after reboots

I recently built my won desktop running Arch. Every thing works fine except for printer. Printer is Brother MFC-290c. It is a Multinational printer (i.e Scanner and printer together).
Once I configure the printer it works fine until the next reboot. After reboot printer user/group changes to root:scanner.
# ls -l /dev/bus/usb/005/002
crw-rw-r-- 1 root scanner 189, 513 Jun 9 07:17 /dev/bus/usb/005/002
So after every reboot I need to do "lsusb" to look for Bus and Device ID for the printer and change its owner/group to root:lp. After this step is performed Printer works fine until next reboot.
$ lsusb
Bus 005 Device 002: ID 04f9:01fd Brother Industries, Ltd
Bus 005 Device 004: ID 045e:00f9 Microsoft Corp. Wireless Desktop Receiver 3.1

Bus 010 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 011 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
How can I make sure that whenever I plugin this printer its user and group is root:lp instead of root:scanner

SOLVED :D:D:D
Thanks Strike0. That was a push in right direction. After reading your reply, I decided to take a look at my udev rules. There was not one for my printer but there was one for the Scanner. I do not yet know how to read udev file, but sure enough it looked as if it was causing all problems . Renamed the rules file for the scanner to see if everything works fine in its absence. Rebooted, Printer and scanner are both working fine now.

Wireless not working after suspend (madwifi)

Hi there
I successfully converted from Vista to Archlinux! Everything's working fine (yep, I'm a bit proud as this my second try at linux ) except that after I suspend with powersave my wlan is not working anymore. I've also tried to unload the ath_pci module and restart the network in /etc/powersave/sleep but that doesn't seem to work.
I guess it has something to do with the network deamon because when I try to restart my network manually it says that dhcpcd is already running for ath0... Oh, and also the iwconfig for ath0 seems to be perfectly correct after suspend...
Here's the network part of my rc.conf:
lo="lo 127.0.0.1"
eth0="dhcp"
ath0="dhcp"
wlan_ath0="ath0 essid FeelGood key s:******"
WLAN_INTERFACES=(ath0)
INTERFACES=(lo !eth0 ath0)
Any ideas? Help would be appreciated

Well, maybe you already know this, but: ath_pci (the madwifi driver) is among blacklisted modules (/etc/hibernate/blacklisted-modules), so it gets unloaded during the suspend process. That screws up whatever wireless connection you might have had before suspending. Now if you have the option LoadModules auto in /etc/hibernate/common.conf, it should get loaded after resuming - but that of course doesn't renew the connection. So that I do is I have a short script that calls /etc/rc.d/network restart, and I run it manually after suspending to renew the connections.
BTW, I have this in /etc/hibernate/common.conf:
UnloadBlacklistedModules yes
LoadModules auto
EDIT: Eh, B managed to post before I finished writing this :)

Disabling E-mail notifications not working after reboot

Hello. It seems that the mail notification and the mail count still persist even if I have it disabled on the settings after rebooting. I've checked the settings after reboot and it is still set as disabled (after following the guide), but the notifications still appear. Is this an bug on the on the app that needs to be fixed? Or am I missing something? Thanks.

I've had a number of problems with the Playbook not recognising the settings I've chosen. In this case, with disabling email notifications, it resets after each reboot.
I've found that if I go into my the Messages app, and then into Message Settings, it shows that alerts are set to be off (display message count, and display new message indicator). The fix for me is to enable alerts, go back to main app screen, then go back into settings and disable alerts once more. At that point the settings seem to stick. So whenever I reboot the playbook, I just have to do that and notifications will remain off until the next reboot.
Let us know if that works for you too. Maybe it will help the engineers figure out what's wrong.

WRT54G wireless not working after upgrading to windows vista, please help

Hello everyone....
I have a few problems. I upgraded to Windows Vista and cant seem to get my wireless internet working. My router is WRT54G wireless-g broadband router. Ever since I upgraded Vista my xbox 360 will not connect.
I just bought a new wireless web camera and that does not work either because the wireless is not working.
Any suggestions on what I should do to solve this issue?
I noticed when I goto 192.168.1.1 my firmware version is Firmware Version: v3.03.9 does that have anything to do with it? Is there a more up-to-date version that will help?
Hope to hear from someone.

I have the same problem, and so does my son, he has a toshiba satellite new laptop and I have an acer new laptop, both have Vista on them, and my wife has XP and has no problem getting on teh router, but i have this problem everyday.
Eventually it will all of a sudden show up and connect and start working, then if you laeave your computer in standby movde overnight, it will still work in the morning, but if you shut down comeplety you will lose the connection for who knows how long. what is the fix Linksys?
(Edited post for guideline compliance. Thanks!)

My ipad2 wireless not working after the update to ios 6.1.3, what can I do?

Hi, My Ipad2 could not connect again with the wireless after updated to ios 6.1.3. Pls what can I do?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Well, the above two links have the problem similar to mine but not exactly. In first one there is a problem with network manager - that it is unable to restart after coming from sleep mode while that is not a problem in my case and I tried all the solutions provided in the second link, but didn't work.
What I figured is when I execute '#pm-suspend' and then close the lid. Then, after I open the lid I wireless works fine. 'pm-suspend' is not invoked if I close the lid. So I needed to invoke the above command when an acpi event is generated when I close the lid. So here is what I added in the /etc/acpi/handler.sh file
button/lid)
case "$3" in
close)
(sudo /usr/sbin/pm-suspend) #added
open)
This works fine for now. Still, I don't know why this solution works - Why executing pm-suspend solves my problem?

Himachi not working after reboot windows 10

2 of my cleints decided to upgrade their pc's to windows 10. After doing so they can no longer browse the remote server at their office location. If I uninstall himachi and reinstall it works but as soon as i reboot it goes back to being unable to ping or browe file shares. I was able to get ping working again by going onto the server and changing allowed connections in himachi details to all from these 2 clients but i still cant browse. Everyone running windows 7, 8 or 8.1 can still browse the file shares without a problem. any ideas?

SB wow wireless not working after firmware upgrade

Hello,
In the beginning of this year I bougth a pair of Sound Blaster World of warcraft wireless headset. And there have been alot of trouble with them, I've been using the latest software but not the latest firmware ever since then.
And every now and then my mic stop to work, I could hear sound but the mic was totally dead, and all of a sudden, of no logical reason the mic started to work agian.
So I thought a firmware upgrade could make them work better, but no, i upgrade firmware from .9.x to .0.x.
And guess what happens? Nothing works no, not the sound, not the mic, the USB trasmitter cant even sync with the headset anymore.
Ive tried a million things now, some of them are:
. Just tried to reinstall it, didnt work
2. Tried to install it in winxpsp3 compability mode, didnt work.
3. Tried to clear all temp-folder (the temp-folder under c:\windows\temp and the user-temp) after Ive uninstalled it, didnt work.
Im running on Windows 7 Professional x64 edition.
What could cause this? I havnt tried to install them on a XP-computer yet tho. But I have to get them work in Win7, since i cant downgrade just because of a headset, huh?
Thanks,
Johan

Ok, please redirect me to a tecnical supportpage where I can find potential solutions,
- and instructions how I do for example a downgrade of firmware?

[SOLVED] wireless not working after -Syu upgrade

Hi everyone,
after an upgrade today (though it's been awhile so unfortunately it was a lot of upgrades), Arch doesn't even seem to recognize my wireless card exists anymore. If I type ifconfig, it only shows
eth0 Ethernet ...
lo ...
whereas before eth1 existed as my wireless.
Thanks for any help!
Edit: I should mention that I normally used wicd. I couldn't seem to get the standard network or networkmanager to work either, though, as no wireless device exists.

I had a similar problem after the kernel upgrade with my Broadcom BCM4312 wireless card (on a Lenovo S10-2 netbook). What worked for me was recompiling and reinstalling the driver in AUR: http://aur.archlinux.org/packages.php?ID=19514, using the little hack suggested in the comments at the AUR package: in the file include/linuxver.h I changed the line
#include <linux/autoconf.h>
to
#include <generated/autoconf.h>
(If you just try to build the package without this change it won't work).
It worked perfectly afterwards (I'm using networkmanager, not wicd, but this shouldn't be a problem).
Of course, the solution depends on your own wireless card, so more details might help.

HP C6180 Wireless Not Working After Upgrade to Mavericks

I've a Macrbook Pro running Mavericks. My printer is an HP C6180. Prior to upgrading to Mavericks from Lion, I had no issues printing wirelessly. I upgraded to Mavericks and I'm unable to print to the printer through wireless. If I connect the printer to the Macbook via USB it works fine. I connected it through USB and ran Software Update. An update for the HP driver was found and installed. I'm still unable to print wirelessly. Both Macbook Pro and printer are on the same wireless network. Nothing has changed with the wireless network. The only thing new is the upgrade to Mavericks from Lion.
I found a similar post Unable to Connect to Printer HP Photosmart C6180 which indicated deleting the /Library/Printers/hp folder, restarting, and then reinstalling the the drivers using software update helped. I did that as well with no luck.
When I try to add the printer it's just not in the list of printers available.
I appreciate any feedback someone might have.

2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
