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] 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.

Printer loses wireless connection after some hours

Hello to all!
Printer is connected and I can see on the screen correct IP. Desktops with Win7 and Ubuntu are used. After switching on printer works properly, but several hours later its unreachable from both systems. Printer shows connection, I can see it in router web access tool, but it is unreachable. I have to switch off printer, reboot the router, then switch on printer - and it works. Not very comfort.
Does anybody know how to fix this bug?
This question was solved.

Hi @varspb,
Welcome to the HP Forums!
I noticed that your HP Deskjet Ink Advantage 6525 printer is losing wireless connection after some hours with Windows 7 and Ubuntu. I am happy to look into this connection issue for you!

Tips for preventing wireless connection issues
The following tips can help prevent wireless connection issues:
Move the printer and the computer or access point (router) closer together.
Remove any metal objects between the printer and the computer or access point (router). Objects such as refrigerators or metal bookcases can interfere with wireless transmission.
Move any device that emits radio signals farther away from the printer. Devices such as microwaves and cordless telephones can interfere with wireless transmission.
Consult the router manufacturer for updates and configuration of your router.
Make sure that your computer is not connected through a VPN. You cannot access your printer on your wireless network while connected to a VPN.
Also, please take a look at this website, HP Wireless Printing Center - Troubleshooting Issues.
Hope this helps, and have a good day!

No wireless connections after upgrading to leopard!

Lost all wireless connection after upgrading to 10.5 osx. Getting frustrated with the upgrade after spending two hours on the phone with apple tech and was told that it was a third party issue! Able to access wireless with security turned off, but once I set sec password (WAP) no connection. What is strange is that I can receive and send email but no browser. All other Mac's/PC's connect fine. Other mac's have not been upgrade! Does anyone have any answers???

see my post here: http://discussions.apple.com/thread.jspa?threadID=1244216&tstart=0

My macbook, OS 6.7, drops my wireless connection after about 10 minutes - help?

My macbook, OS 6.7, drops my wireless connection after about 10 minutes - help? The lynksys signal works on other computers/iphone but not on my older macbook.

Same problem, IMac with OSX. Everything else in the house is fine - Netfilx, pc's, radios - Mac drops the wireless after a few minutes. It sits closest to the router. Imac will be OutMac soon if no solution comes along.

[SOLVED] Losing network connection after suspend

Lately I'm having this peculiar problem. When resuming after suspend (specifically, pm-suspend), I have no network connection. I first noticed this on March 31st. The only thing that changed was that I upgraded these packages:
openssl-1.0.1-2-x86_64.pkg.tar.xz
xf86-video-ati-6.14.4-2-x86_64.pkg.tar.xz
lib32-libdrm-2.4.33-1-x86_64.pkg.tar.xz
libnotify-0.7.5-1-x86_64.pkg.tar.xz
xz-5.0.3-2-x86_64.pkg.tar.xz
vim-taglist-45-5-any.pkg.tar.xz
But I'm pretty sure I would have suspended and resumed successfully at least once after that upgrade.
Can anyone suggest what I should look at to try to diagnose this?
Thanks

Same issue here. Looks like dhcpcd crashes during or after running /usr/lib/dhcpcd/dhcpcd-run-hooks on resume from suspend. I'll try downgrading until this is fixed.

Wireless Connection after 10.4.8 Update

I want to try and update again to 10.4.8. Has the wireless connection issue been resolved yet? The problem I was having before was when my mac went into sleep mode or I would reboot the wireless connection would be dropped. I tried just about everything I found on this board, but nothing worked. I had to archive and restore my mac back to 10.4.4. Is it safe to update, if not is there a fix for after I update?
Any help would be great!.

If I had an IntelMac I'd wait, or certainly not go past 10.4.7, and at that I'd surely use the bigger Combo Updates, not any of the Deltas.
Yet if I did try 10.4.8... it'd be installed on a seperate FW drive for testing... without messing with the working install.
All that being said... I still am at 10.3.9 or less on all my important work machines... only have Tiger on 2 machines to help sort out/test all the 10.4 problems!

No wireless connection after pacman -Syu

Hi,
I'm almost new in this forum. Recently I did a system upgrade (or update?). After that the wireless connection didn't work again. I used the search function but I didn't find a solution so I reinstalled networkmanager and the wireless card driver (from AUR). Then I did everything mentioned in these wikis:
http://wiki.archlinux.org/index.php/Wireless
http://wiki.archlinux.org/index.php/Broadcom_BCM4312
http://wiki.archlinux.org/index.php/NetworkManager
But no success
The output to lspci | grep BCM43 is:
04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
The output of iwconfig is:
lo no wireless extensions.
eth0 no wireless extensions.
These are the relevant lines of rc.conf:
MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated

#eth1="dhcp"
eth0="dhcp"

#gateway="default gw 192.168.0.1"
#ROUTES=(!gateway)
# DAEMONS
DAEMONS=(syslog-ng hal !network networkmanager !netfs !wicd crond fam gdm)
I really appreciate any help, thank you very much in advance,
Luis Pablo

I'm making some progress. I realized I forgot to blacklist ssb and ndiswrapper. I compiled the driver from the Broadcom website. This is the new modules array in rc.conf:
MODULES=(lib80211_crypt_tkip wl !ndiswrapper !b43 !ssb fuse snd-hda-intel)
Now "sudo iwconfig" output is

Printer keeps dropping wireless connection after working for a while

My computer stops being able to communicate with the printer wirelessly even thought the printer says it is connected to the network and both the printer and computer are on the same network. What happens is I connect the printer to the network and print something from my computer. Then, after a short while, half an hour maybe, when the printer shows it is connected to the network, I try to print but my computer can't find the printer. The message say the printer cannot be found. If I go to the printer, and reconnect with the wireless connection wizard I can print. But after a short time, I won't be able to print again and have to do the wireless connection wizard again. Wireless direct is off. Don't know if that matters.

These settings are for setting up your wireless printer to stay connected to your router, keep wireless devices better connected and makes your router secure and hack proof.
Set a static IP in the printer (click here) outside the DHCP range of the router (check your manual). This is for Linksys routers but can be used for all routers. Verify your DHCP range and change this first if needed. More Wireless Printing help is here (Windows solution 4, static IP).
Verify in the printer that 'Auto Off/Sleep' is disabled. Use the Embedded Web Server (EWS) by going to the printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer Assistant, Printer Home Page (EWS). Also check your Printers Properties.
If the printer supports and has IPv6 enabled, turn off IPv6 in the printer.
If needed and you assigned a static IP address, try using 8.8.8.8 for the Preferred DNS server and 8.8.4.4 at the Alternate DNS server.
In the router: (Refer to your router manual for information)
Use a fixed wireless channel like 1, 6 or 11, never 'auto', try channel 1 first then the rest.
Set router to 20Mhz only, or 145Mbps depending on router.
Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your system now and helps with wireless connectivity (if you want to know why, search the web).
If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same, they must be different for all bands, even for any Guest networks.
SSID broadcast must be enabled.
Save all settings. Power off both, wait 2 mins. Power on router wait 2 mins.
Power on printer and verify it reconnects to router.
Windows 7/8/8.1 Is Network Discovery on or off?
Control Panel/Network and Internet/Network and Sharing Center/Advanced sharing settings.
Under Home or Work (current profile) / Network Discovery.
Select "Turn on network discovery" and save changes.

Problems with Wireless connection AFTER 10.4.2 update

I have read several topics on wireless problems AFTER the 10.4.2 update and wondering if anyone (or Apple) has found a fix to this problem. I cant get to my network or the internet via airport. I have tried zapping the pram, resetting the permissions, rebooting, checking for more update on a wired connection, reinstalling both 10.4.2 combo and 4.2 update and still nothing. This happened RIGHT after the reboot upon completion of the update. Im stuck and wondering if anyone has a solution or has any one SUCCESSFULLY contacted Apple and have they got a solution to fix the problem??

I'm having the same problems with accessing my airport base station (first generation snow at 4.0.9) after loading the airport admin 4.2 patch. I loaded the 4.2 patch on my g5 and G4 running 10.3.9. The response/across of the wifi connection is very poor. I can't use chicken of the VNC to manage the G4 from the G5 anymore at all due to the slow response and accessing the internet via either the G4 or the G5 is like a dial up connection. The broadband speed test results are 192mb to 274mb up and similar down.
I have a 12"powerbook (DVI 1gig version) with 10.3.9 that I have not loaded the 4.2 patch on and I am not having any issues with wifi access to the base station or the internet. broadband logs in right at 2.8mb via DSL. I also have a Dell laptop that I access the internet through the airport base station and I have no issues with speed and the same 2.8mb broadband speed test results.
Conclusion something in the airport 4.2 patch has changed the airport cards ability to see the base station.
With all that said, my question is - How do I back out of the 4.2 airport admin patch provided by apple or how do I resolve the slow response times between the airport cards in the G4 and G5 and the base station?
Any help?

[Solved] No wireless connection after reboot.

I installed through a wireless connection. I installed inside of VirtualBox, and I installed wireless_tools, wpa_supplicant, and wpa_actiond dialog. So I had wireless internet on the live cd, but not after the install. Is there some driver that I am missing? Is there some VirtualBox special feature I am missing?
lspci | grep -i net = intel corporation 82540em gigabit ethernet controller
I don't think I need to install any additional firmware for this driver.
iwconfig = enp0s3 no wireless extensions
lo no wireless extensions
I tried adding manually loading iwl3945 and iwl4965, one of which I think is my driver.
Any help would be appreciated. Thanks.
The fix was typing "systemctl enable dhcpcd".

Photosmart 6180 All-in-One Wireless Connection After Windows 7 Laptop Added to Network

I replaced a broken Vista laptop with a new Windows 7 64-bit laptop. After I installed my Photosmart 6180 All-in-One, the printer stopped working correctly when we try to connect to it wirelessly.
I followed all the directions HP provides for updating the printer software and drivers for Windows 7.
We've tried all the suggestions for resetting the printer that we can find on the HP forums.
The printer works properly when connected via USB cable to a Vista laptop.
I was not able to get the printer to work via USB cable connected to the Windows 7 laptop.
When we try to connect via the wireless signal, regardless of Vista or Windows 7, the printer goes into an endless initialization loop.
We need to determine whether achieving a wireless connection is hopeless. If it is not, we need step-by-step instructions on how to resolve the issue.
The security system for the printer is WEP. We connect through a wireless router provided by Verizon FIOS.
Many thanks in advance for your help.

Some of HP's printers do not support WEP shared. If you are using WEP shared this could be the problem. I would suggest turning off the WEP security temporarily to see if that fixes the issue. If it does then you can look at changing the security to WEP Open system authentication.

WRT300N V1.1 - Firmw v1.51.2 - Problems to get wireless connection after long idle time

Hello,
I have a WRT300N, v1.1 with latest firmware available (v1.51.2).
I've been experiencing a strange problem:
1. After long idle time (router is on, no devices are using it wirelessly), no device can get a wireless connection;
2. I have tried using different OSes (Windows XP SP2, Windows Vista, and Symbian OS);
3. Wireline connection to a FE port works (if I plug a device using the cable, I can get an IP address and navigate to the internet).
4. If power reset it (WRT300N), I can get wireless connections working again.
Is this a known issue?
Thanks, Gustavo

Well as you are able to go online from your Hardwired Computer, then i think you need to make some changes on the Wireless Part of your Router. Follow this settings on your Router, i think this might solve the problem.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Wide-40MHz and change the Wide channel to 9 and Standard Channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on save settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select AES...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone.
NOTE : Passphrase should be more that 8 characters...
Click on Advanced Wireless Settings
Change the Beacon Interval to 50 >>Change the Fragmentation Threshold to 2304 Change the RTS Threshold to 2307 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

Printer drops wireless connection after some time

Have HP Laserjet P1102w printer. (Serial# edited Serial Number by Moderator) (Firmware 20130703)
Windows 7(64bit)
Printer on wireless home network.
For a period of time the printer prints wirelessly and prints from EPRINT EMail address OK.
Normally Wakes itself when print received.
After some period of time,however,the printer quits responding.
It did not wake when print received.Normally wakes itself when print received.
I manually turn it back on (front panel power button) and observe the following:
The blue wireless light is on.
The blue error light is on indicating no error.
the green light also is on.
Open Control Panel(View devices and printers) on computer and it shows printer error.
Can restore normal operation by unplugging for a few seconds and turning back on.
Can also restore normal operation by turning off and back on.
Will quit responding again after some period of time when trying to print.
Tried Windows troubleshooting and HP "Print and Scan Doctor".Tells me to reboot.
How can I fix this problem?
Can't reboot by unplugging or powering off when away from home so can't use ePrint email address to print.
Can't print when away from printer when it quits responding.
Thanks for any help.

These settings are for setting up your wireless printer to stay connected to your router, keep wireless devices better connected and makes your router secure and hack proof.
1. Set a static IP in the printer (click here) outside the DHCP range of the router (check your manual).
   This is for Linksys routers but can be used for all routers. Verify your DHCP range and change this
   first if needed. More Wireless Printing help is here.
2. Verify in the printer that 'Auto Off' is disabled. Use the Embedded Web Server (EWS) by going to the
   printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer
   Assistant, Printer Home Page (EWS).
3. If the printer supports and has IPv6 enabled, turn off IPv6 in the printer.
4. Assign the printer a static IP address, try using 8.8.8.8 for the Manual DNS server and 8.8.4.4 for the
   Alternate preferred DNS server.
In the router: (Refer to your router manual for information)
5. Use a fixed wireless channel like 1, 6 or 11, never 'auto', try channel 1 first then the rest.
6. Set router to 20Mhz only, or 145Mbps depending on router.
7. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
8. Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your
   system now and helps with wireless connectivity (if you want to know why, search the web).
9. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same,
   they must be different for all bands, even for any Guest networks.
10. SSID broadcast must be enabled.
11. Save all settings. Power off both, wait 2 mins. Power on router wait 2 mins.
12. Power on printer and verify it reconnects to router.
Windows 7/8/8.1   Is Network Discovery on or off?
Control Panel/Network and Internet/Network and Sharing Center/Advanced sharing settings.
Under Home or Work (current profile) / Network Discovery.
Select "Turn on network discovery" and save changes.

Error message on wireless connect after latest netcfg update

The connection works, but I since the latest update from this morning I get the following message when connecting to the wireless
network:
nl80211: 'nl80211' generic netlink not found
This is my connection profile:
CONNECTION='wireless'
DESCRIPTION='A simple WPA encrypted wireless connection'

Gusar's answer is correct, you can remove this error (temporary solution) and marginally speed up connecting to wireless by running this patch:
