[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.

Satellite Pro U400 - Lost network connection after suspend

I have a Toshiba Dynadock. My network is connect directly in dynadock.
When suspend my Satellite Pro U400 and after restart for continue working I lost my network connection. Then I shutdown my computer and disconnect/connect Dynadock I can continue working.
What's the problem?
Version software Dynadock is 2.0

Hi
I see you have switched from Vista to XP.
First of all I recommend updating the BIOS.
As Im not mistaken you should find a newer BIOS version on the Toshiba European driver page.
Then you have to update the Win XP to the latest state!
The XP should be up to date and all service packs, patches and MS fixes should be installed in your notebook.
Then access the device manager and mark in every USB root hub you have to disable the option called Allow the computer to turn off this device to save power
You can find this option in properties -> Power management tab

Randomly losing network connection over wireless

Shortly after installing the 10.4.5 software update, my G4 iBook with built-in Airport Extreme card has been losing connection with increasing frequency. Built-in Ethernet use is unaffected. I'm calling this problem thrash-and-drop.
1. When it's losing signal, processor activity goes through the roof. I had Activity Monitor running during a thrash-and-drop. kernel_task CPU consumption goes from under 1% before the event, to over 80% during the thrashing, and back under 1% after the thrashing stops. The activity is so bad the cursor can't be controlled: using the track pad sends the pointer all over the screen or nowhere at all.
2. This has been observed to occur with two different wireless base stations: A Linksys WRT54G and an older SMC 802.11b router. Either router is within 10 feet of the computer. Only one is running at a time. There are no other base stations in range.
3. Another iBook G4 (OS 10.3, Airport Extreme card (not built-in)), sitting next to it, shows no change and its wireless behavior is unaffected.
Initially, this seemed more likely to happen when Safari was loading Flash-heavy pages. And after thrashing and dropping a connection, it was able to reconnect after either a reboot or a five minute sleep. Currently, it can't connect to a base station for more than a minute. Most recently, it thrashed and dropped while I was selecting the base station to use. This is true regardless of the application running. In fact, it will thrash-and-drop when there are no user applications running at all, after a fresh reboot.
I've tried the following things to address the problem. None have affected the thrash-and-drop problem. Admittedly, most of this is random:
1. Back up and delete network preferences in /Library/Preferences/SystemConfiguration
2. Turn off IPv6 in System Preferences/Network
3. Back up and delete network preferences in ~/Library/Preferences (com.apple.NetInfoManager.plist and com.apple.NetworkUtility.plist)
Has anybody else seen this problem? I want to blame it on the 10.4.5 upgrade but I haven't seen anybody else complaining about 10.4.5 doing this to them. If there's something I can do to fix this in a software setting, I'd much prefer that to yet another roadtrip to the Apple store.
1.33 GHz G4 iBook Mac OS X (10.4.5)

Hi!
I have the same problem of randomly losing network connection over wireless, though mine is hardly related to surfing.
I have an external storage drive in which I use for backup of my stuff, and I access the drive via my modem, using the airport. Of late, I noticed that when copying files from my iBook to the external drive, the connection would suddenly drop before the transfer is completed. This began to occur with increasing frequency, particularly when transferring large files.
I have since abandoned wireless connection, and reverted to my trusty cable. Still, I admit that I'm really curious about the cause of the apparent lack of reliability with my wireless connection. Has it something to do with the airport?

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

FP1600 loses network connection after a few hours

My FP1600 loses its network connection after a few hours. It is part number 185690C-01, with firmware 4.11. I am running FieldPoint Explorer version 3.0.1 and LabView 6.1 from Windows XP Professional. I set it up, and everything runs fine for 4 hours or more. I do not have the network watchdog enabled, and the FP1600 is in constant communication with the host computer in any case. Sometime in the middle of the night the communication is lost. The FP1600 link light
is on, and it is still receiving packets, but it will not respond to a ping or any other communications. Only a power cycle brings it back. The FP1600 is sitting right next to the host computer, both attached to the same network switch. There is no interruptio
n of network services to the two.

Hi Heinz,
We are also trying to troubleshoot this same problem (Intermitten network connection loss with FP1600 Ethernet Module - Error code "33163", Error Message - "FP1600 Connection to module has been lost."). We have checked other possible causes for this sort of behaviour. Including independent assessment of netowork availability at the time of error reporting, connecting dedicated power supply to the FP1600 module, temperature of cabinet housing the module (which is between 10 and 50 deg C), disconnecting sensors connected to various I/O modules connected to this module, increasing duration of parameter "time out" (the time module will wait before reporting an error if it can not access network). However, none of the above resolved the intermittent and random network loss errors.
The MAX version is 3.0.2, and the firmware on the module is 4.17, Labview version is 7.0 and the Operating System is windows NT.
I was wondering is there any information about this problem from any user or NI recently. The only solution looking in to this discussion forum seems to be replacing the module.

DHCP Failover, one DHCP Server Partners Supnet is deactivated, Clients losing network connectivity for 3 sec. after renewing they IP Adress

Hello,
currently we are using two W2K12R2 DHCP server configured in "load balance Mode". On DHCP1 the IP-scope with failover partnership to DHCP2 is deactivated. DHCP2 is working fine. Now we register that 50 percent of our clients (W2K8R2 application
server) losing the network connectivity for 3 sec. after rereleasing they IP-Address. On DHCP2 servers eventlog we receive a lot of
BINDING ACK reject events 20291 and 20292 for these IP addresses entries.
These 3 sec. of loosing they Network connectivity is our big Problem because the Client application (W2K8R2 application server) cannot handle these timeout. It looks like a
DISCOVER-OFFER-REQUEST-NAK cycle that are described here:
http://blogs.technet.com/b/teamdhcp/archive/2014/02/26/dhcp-failover-patch-to-address-a-reservation-issue-and-another-issue-related-to-failover-partner-not-accepting-state-transition-from-bad-address-gt-active-has-been-released.aspx#pi47623=2
there is a solution to prevent the 3 sec network failure?
Rgds

Hi Steffen,
Have you applied KB2919355 in the server?
If issue persists, please check the detailed information about the event. It will tell us why does the server send the NAK.
Best Regards.

Keep losing network connection, especially after waking from sleep, but...

For a while now, my G5 would have intermittent problems not finding the network after it has been asleep for a bit. I used to resolve this by resetting the router, or sometimes putting the Mac back to sleep and resetting the router.
Lately, I discovered another fix: wake up my MacBook. The MacBook wakes up, connects wirelessly, and sees the network, and shortly thereafter, the G5 sees it too.
I cannot interpret this. Why would it be that the G5 would fail to see the router until after the MacBook is awake (and sees the router)? I never could figure out which component was at fault before, and this further confuses me. I mean, it seems that it has to be the G5, since if another computer can see the net on the same network, it would rule out the router and the cable modem. Right?
So what do I do about the G5, then? Yesterday, it was getting to the point where every time I woke up the G5, it wouldn't find the network (until after I woke up the MacBook).

Hi, Brent:
I would not be too quick to start swapping things out (esp. expensive things!) without letting the discussion flow. I have never seen an answer that worked except updates and not all do... see below.
My Dual 2.5GHz G5 has been doing this on and off for years. It has been networked wirelessly since I got it and I am on my third router now for other reasons. I run two other Macs (G4 mini and early IMac/Intel) as well as two laptop PCs, all wireless. None of the other machines ever has this intermittent connectivity issue - just the G5. The symptom is a stalled browser (Safari or FireFox) with the wireless symbol almost always at four bars. Once in a while (like today), the bars will fade down to two for a while, but rarely. Absolutely the only temporary fix I have found successful is to switch airport on and off. Cure may hold for a while or it may not. Have noticed some apps using airport still seem to work (an old MacStumbler utility) even when Safari locks up. Thought it might be a Safari bug, but FireFox does the same thing.
IMHO, this is fundamentally related to a G5 software issue or interaction with the airport or network card. As I noted above, code evolution is a strong factor in my experience. My problems come and go tightly linked to software updates. It is usually a night-and-day change. I am at 10.4.11 on all Macs here; problem had not been around until I ran the last big update to 4.11. Interestingly, my daughter owns a very new iMac with Leopard and has seen the same type of behavior since Day One. I have also seen this problem mentioned about Leopard and iMacs in the lay press.
Wish I could offer a solution, but I am just waiting it out again.

All in One Printer, losing network connection

I have an HP Photosmart, 5510. It's only about a year old but is now always losing the network connection. I have it set up properly (it has actually worked!) to the wireless router. Most times now when I need to print, it tells me the printer won't communicate with the computer. I have taken it off the network, put it back on, and it says it is all connected. I have printed out the network status page, all is okay, no problems found. Why then am I still unable to print? This is very frustrating.
I have it set up to my Macbook Pro and my iPad. It has previously worked on both devices, but I can't seem to get it back to working order now.
I have looked at the forum here and have seen many many people with the same problem, but most seem to be using a Windows operating system. Any ideas on what to do? I really need to print!!
This question was solved.
View Solution.

I feel that perhaps either my post was in haste or in error since I did not see the above solution you provided when I posted this. I do not mind helping you out with router and network problems either way, but since you do not know the name of your router, it will be hard for me to assist with that. I will say, you can always contact your internet service provider and have them check for a firmware update if you have to reset the router that often. If you look on the back of the router you will see little numbers (specifically a model number).
Is that IP address that of the router or the printer?
Either way, I am very happy to hear you were able to get it working again. If you need any more assistance let me know which device has that IP address and at least a model number so I can look up your type of router and let you know if a firmware is available. I'm happy to help!
Don't forgot to say thanks by giving "Kudos" if I helped solve your problem.

WRT120N losing network connection

Hello
Just after some help with my home network. I have a Dynalink RTA 1320 DSL connected to my WRT120N which is wired to my PC which is running Vista. I have a new HP laptop running Windows 7 which is connected wireless to my home network.
I have no issues with my internet connection, both PC and laptop can access the internet at all times.
The problem I have is that for some reason, maybe after 5 mins or so, my laptop drops its network connection with my PC, and vice versa, so I cannot access their shared folders(either from my laptop to pc, or pc to laptop). I have checked firewalls etc and everything else in between. After reading some posts I see that others may have the same problem.
Any help would be much appreciated. Thanks
Solved!

If you have security firewall or anti-virus on your computers then,try disabling them and check.Also,check for the latest driver for the adapters on your computer and update them.

Losing network connection (phone, text, data)

For the past couple of weeks I have had problems losing my network connection affecting phone calls, text messages and data access. The problems seem to be occurring more frequently, and have not been able to identify a consistent pattern yet.
Phone: On 2-3 occasions recently, I have had calls dropped. I see that I have no [phone] network connection. In each case I've been in a location where I frequently make calls. Twice this was while on a major freeway in the SF Bay Area. In each case I do get a signal back, but it takes several minutes until I re-acquire a signal.
Text: On multiple occasions (3-4 in the past week), I have tried to send text messages from my office (in San Jose), where I have not had problems in the past. After waiting for several minutes to re-acquire a signal, I re-booted my phone and my text messages were sent as soon as the phone re-booted. Note: changing the phone to airplane mode and then off, did not resolve the problem.
Data: On multiple occasions (8-10 times in the past couple of weeks), I noticed that my phone shows "4G", but no arrows and I have no data access (i.e. no access via web browser, can't use any email apps, can't use any apps that use data access). Once I lose the data connection, it never re-acquires the network even after moving and/or waiting in excess of an hour. The only way to re-acquire data is to re-boot my phone.
This seem to have started 2-3 weeks ago, but definitely getting worse over the past week - very, very frustrating!
Using Samsung S4, running Android 4.4.2. I don't recall installing any new apps or new O/S versions in the past couple of weeks, though many updates auto-installed.

I tried removing/replace the Sim card. Still have the problem.
I got really frustrated with this and after spending over an hour on the phone with technical support and then with Assurion, I got them to replace my phone, with a replacement S4.   Spent another couple of hours getting my phone reconfigured, including having to spend another half an hour on the phone with technical support because the new phone wasn’t activating on the network.   And, still have the same problem on two consecutive days where the phone hangs when I try to make a call at the end of the day. (Though I had been able to make a couple of calls during the day).
So:
·         It fails in safe mode
·         It fails if I set the network to LTE/CDMA rather than Global
·         It fails after re-seating the Sim card
·         It fails with a replacement device

After installing gnome 3 I can't connect to my wireless network any more. I start gnome using 'xinit gnome-session' after loggin in at a command line. Here are some relavent ouptuts:
$ ifconfig

Hello,
I'm having problems with my wireless network connections, too. I did a fresh arch install with gnome3 some days ago to avoid any issues when upgrading, but i just can't access any wireless networks now. Everything else works like a charm, though. I followed the usual steps to set up my network/wifi with all the required modules and packages (broadcom-wl from the AUR, etc.) but it doesn't work like it did with gnome2 and xfce4.
My iwconfig/ifconfig output looks like dave1022's. Don't know if this is of any help...
The nm-applet in the gnome3 "panel" actually lists nearby wireless networks, but once I click on one of them, gnome asks me for authentification with my root password (user password does not work). I don't think it should be this way. If I enter my root password here, nothing happens whenever I click on the concerned network to connect to it. I deleted the /etc/NetworkManager/system-connections/<SSID> file to reset the authentification process.
I tried to consult the gnome3 pages in the wiki, but couldn't find any valueable hints either...does anyone have any idea what I might have done wrong or forgotten?
It's exactly the same for me and it's driving me nuts. I'm using iwl3945
[EDIT]
Well... actually installing the applet solved it for me. Is the applet actually needed for Gnome 3 or is a workaround?
