Won't reconnect to network when awoken from sleep

What would cause my G5 to not be able to connect to my network when awoken from Sleep? The only way to resolve this is with a complete re-boot of the system - too much like a PC, IMHO.
The G5 will not automatically re-connect nor is it possible to connect manually by typing in the name of the network as well as the password. Again, only a re-boot of the G5 will allow me to re-connect. iBook G4 has never had a problem with this (which is on the same network).
Any ideas?
TIA

X220 very slow reconnecting to WiFi when resuming from sleep

So my X220 with the Intel 6205 card is having issues reconnecting to WiFi when resuming from sleep or hibernation. It takes about a minute for it to do so, though occasionally it will reconnect right away. Maybe 1 out of 20. When doing a cold boot or restart, it connects immediately upon the desktop showing up.
This was not always the case, in fact when I first got my X220 in June, I have not had this issue.... In fact, I don't know when it started happening, but it was maybe a couple months ago. I just thought it was my old router going bad. Well I got a new router, and it still happens. I have the latest Intel WiFi drivers from Lenovo, and I even tried downgrading to the previous driver from Intel's site. Still the same problem. I tried setting a default profile in access connections, and that does not help. In fact, it behaves the same way if I totally uninstall access connections as well. In fact I tried this on three different brand routers, and I can reproduce it on all of them (Asus, Netgear & TP-Link) so I think this is not a router issue. Other devices in the house reconnect right away with no issues (iPhone 4, PS3, Mac desktop, Dell laptop).
I currently have BIOS 1.24, but this was happening with 1.21 and 1.23 as well. My X220 originally came with 1.16, and I haven't updated it until 1.21. Unfortunately I don't remember that far back, if the problem started occuring then.
There was a brief discussion about this in another thread, but it went nowhere so perhaps this will get more attention. At least one other user reported the same issue.
Here's a clip of exactly what happens. When i press the button or open the lid from sleep, the windows wifi icon will start spinning for a few seconds, then turn into an X. then only about a minute later, does it quickly connect to the wifi and I have full signal. Manually clicking on the icon and selecting the access point does not speed up the process. It will only connect when it wants to, about a minute after resuming from sleep/hibernation.

Solved!

Normally when a laptop running windows tries to connect to a network, it may also seek to identify certain components on the network, for example, asking the router "Who are you?". In your case, maybe the config are corrupted because the network address entries are messed up. Queries send out to the network come back with no replies, and the computer waited for the default time till timeout and it gives up.

My MBP doesn't remember my Time Capsule wireless network when waking from sleep

My MBP (OS 10.5.8) doesn't remember my Time Capsule wireless network when waking from sleep. Thus, every time my MBP wakes from sleep, I need to select the Airport icon in the upper menu bar, select "Join other network", enter SSID and password. This is very cumbersome. And, I never had this problem when I was using the ISP's provided wireless router/gateway/DSL modem. Adding the Time Capsule and using it to generate the wireless network has introduced this problem.
It appears that this problem has to do with the hidden SSID. I don't need the lecture on how hidden SSID provides no serious security benefit. That's why I have the WPA2 encryption. I'm interested in a solution that will allow the Time Capsule to generate the wireless network, maintain a hidden SSID, continue to use WPA2 encryption, but have my MBP recognzie and autoconnect to this network.
Solutions I've alread tried:
1. Open Network Preferences
2. Select Airport from left hand column (and ensure Airport is at top of that list)
3. Select Advanced
4. Delete all Preferred Networks.
5. Apply settings.
6. Restart computer
7. Return to Network Preferences and from Advanced page, manually add my network with hidden SSID and WPA2 password
This solution works fine as long as I don't take my computer elsewhere and connect to another network. As soon as my preferred networks list gets another network, my MBP stops finding my TC network. Since I take my laptop to a lot of places (it's a laptop, after all...) this is a problem.
As I say, prior to adding the TC on my network (and using it to generate the wireless network), my MBP had no problem keeping 50+ preferred network names/passwords in the Preferred Network list, but always automatically finding/connecting to my home network without the need to "Join other network." Thus, I assume the problem lies with the Time Capsule.
Any ideas?

LaPastenague, thanks for weighing in. Didn't know that the hidden SSID capability was not IEEE standardized, and thus different devices will handle hidden SSID differently. With my admittedly limited knowledge of how SSID/hidden SSID works, I'm still a little confused as to why my MBP would remember the generic router/gateway's hidden network, but struggle with the TC's hidden network.
To my knowledge, when an SSID is broadcast by a base station (Airport, wireless gateway, etc.), a connecting device (like a laptop, iPad, etc.) detects this broadcast--this would be a passive reception of this SSID signal.
When an SSID is hidden, the base station does not broadcast its identification. Rather, a connecting device must transmit the name, and when the base station recognizes the broadcast, the connection is made. That's what you do when you select "Join another network" and manually enter the SSID.
The idea with OS X's Network Preferences is that these steps, whether for hidden networks or broadcast SSIDs, become automated.
Where is the potential for a different chipset between the TC and the previously used wireless router/gateway to alter this functionality? Shouldn't the selection of an SSID by the MBP to broadcast to seek for a base station be a function solely on the MBP? And once broadcast by the MBP, the TC should detect and reply?
Basically, the MBP can connect to the hidden TC manually just fine. The MBP can connect to the old setup automatically just fine. The MBP cannot connect to the TC automatically. Aren't these automatic connection functions solely on the MBP?
I'll try un-hiding the network and re-verifying that the problem is exclusively with the hidden network.

IMac loses connection to network when waking from sleep

Hi There,
We are a small mixed environment of Macs and PCs running on a Windows 2008 domain. One of 2 iMacs that now run Mountain Lion 10.8.5 is having problems when waking from sleep. One of our designers will go for lunch and the machine will sleep for about 30 to 40 minutes. Upon her return the iMac will kick her off of the 3 shares she usually logs into (2 are on Win2008 machines, and 1 is a MacPro running 10.6.8 Server).
If she has files open in any of the Creative Suite Apps, the app will crash and she will have to restart the whole machine. If no files are open then she can usually reconnect to the shares after a short while. Obviously I told her not to leave any files open, but its causing her some headaches.
Its also creating srv errors (id 2012) on our domain controllers, when she tries to wake her machine.
This Imac is a late 2009, and we have a 2011 model that has no issues at all. Both are set exactly the same.
I have reset SMC, Pram, and rebinded to the domain, and searched through these forums quite a bit to no avail.
Any thoughts or suggestions would be much appreciated.

I am continuing to work on this issue, and have tried a number of things based on searching here and elsewhere.
And Lucky Me, I have been able to replicate this behavior on one of other Macs (imac 2011, on 10.8.5). I also see errors on 2 separate Windows file servers on the domain (Event ID: srv 2012).
Below I am posting what seems to be the relevant area of the log.

Any help would be appreciated.

Imac keeps losing wireless network connection when awoken from sleep mode

I recently did a archive and install on my Imac and I am still trying to get the kinks out.
Since I did the archive and install, my Imac loses it connection to our wireless router. I assume it isn't renewing its DHCP lease. In order to get a connection again, I have to restart my cable modem and my wireless router.
My network settings are set to join preferred networks by default. My default preferred network is listed and the security parameters have been fulfilled. I am set up to use DHCP in Imac preferences.
Any help would be greatly appreciated.

Hi, See if this helps...
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point.
Remove your access point with the little minus sign. Launch your keychain access in Utilities and delete your access point keychain entry.
Add it in again after a reboot.

MacBook Pro airport doesn't choose 5 GHz network when waking from sleep

Hi,
I recently set up a Time Capsule [TC] 802.11n (4th Gen) as my airport base station catering for my MacBook Pro [MBP], iPad (1st Gen), iPod (3rd Gen) and BlackBerry 9900. I have it set up in dual-band mode (2.4/5 GHz) with the same SSID, mainly hoping to take advantage of the increased speed of the 5GHz band during Time Machine backups - I get a Transmit Rate of 300 Mbit/s when connected at 5 GHz and 145 MBit/s at 2.4 GHz. Aside from that I don't really care which it chooses to be honest - my internet connection is only 12 Mbit/s. When I start up my MBP from a full shut down within an 'appropriate' distance from the TC, AirPort automatically selects the 5 GHz band and falls back to 2.4 GHz if I stray too far.
The problem arises when I wake my MBP from a sleep (which is pretty much always having closed the lid each time I'm done using it) and AirPort ALWAYS selects the 2.4 GHz band and will never change to the 5 GHz band unless I fully disconnect from the network and then reconnect.
The iPad and BlackBerry both switch happily between the two bands as I move around the house, opting for the 5 GHz when possible and always without intervention so the set-up obviously works.
I think it's a problem in Snow Leopard having read problems around the internet from users who have upgraded from Leopard to SL, most of whom seem to do what I'm thinking, i.e. setting up a different name for the 5 GHz network and putting it higher in the priority list that the 2.4 GHz one, however the solution isn't ideal/elegant and certainly not how it's supposed to work, but I've yet to find a definitive solution from Apple anywhere.
Anyone else having this problem? Anyone found a solution? Anyone heard anything from Apple?
Thanks!

Yes. I'm having a very similar problem. I don't have TC, but I have a netgear wndr4000. I'm always bring my MBP out of sleep and having to manually select the 5GHz band. Even when I know it should. I have different SSID's on each band, and I have tried setting the priority order, but that has another set of problems. When I get a little farther away, it will hook to the 5GHz band at 54Mb, but the 2.4GHz will be at 130Mb at the same distance. I thought it would make some type of smart choice about it.
I had been thinking about moving to a Airport Extreme because I've been told by others that their machines make the correct choice with the SSIDs set the same.
I too am on Snow Leopard, but I'll be upgrading soon.

Intel 3160 in 15t-k000 cannot reconnect to networks after resume from OS sleep/standby

Quite often the Intel Wireless-AC 3160 will be unable to reconnect to a network after Windows resumes from standby/sleep (or perhaps it's Windows' deeper hibernation). The only fix (other than restarting Windows) is to disable the 3160 in the device manager and then re-enable it. Upon re-enable, it immediately reconnects. This happens sporadically, not every resume.
Attempted resoluions (besides disable/re-enable workaround):
Tried multiple networks on both 2.4 GHz and 5.2 GHz bands. Updated the Intel drivers, the issue persists.
Ran Intel PROSet/Wireless "Manual Diagnostic Tool", which passes tests until "Association Test", which fails. Even "Scan Test" passes, but it just can't associate (connect?) with a network.
Windows automatic troubleshooting tool. No resolutions, useless.
EDIT: The issue looks a lot like this one on the AC 7260. No resolutions on that forum, unfortunately.
Windows 8.1Pro 64-bit
Intel Dual Band Wireless-AC 3160 driver version 17.1.0.19
As an aside question, what network cards are usable with the 15t-k###? For example, like the list here for the 15t-j###. Is there a simultaneous dual band card that can be used instead of the 3160? Thanks!

Hi @chappjc ,
Thank you for your inquiry, I am happy to try and help!
I understand that you are unable to connect to the network when resuming from sleep or hibernation in Windows 8 Pro.
If is possible that you card is not set to connect when waking from sleep mode.
Here are links to documents that I believe will help.

Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

Won't accept password when waking from sleep.

a client of mine is having an issue where her mac won't accept her password after waking from sleep. The same password works when she restarts. She has confirmed that caps lock is off. Any Ideas?
I left her a message trying to find out more details about her computer like OS version and stuff. Will update this when i hear from her.

She still hasn't returned my call, but i know that she is able to type. Whether its wifi keyboard or not I do not know.

GT70 internet very slow and sluggish when waking from sleep

My GT70 sometimes is very slow and sluggish to respond when it is awoken from sleep mode. Browsers become unresponsive (hyperlinks don't register as links and require multiple clicks to respond) and internet gets very slow. Speedtest.net reports .50-3mb/s when it is usually 24mb/s and above. The hdd also thrashes about and won't calm down for what seems like an eternity.
This only happens when opening the lid after the machine sits idle for several hours. This is fixed by restarting the machine.
Does anyone know why this laptop would be behaving like this? it is very frustrating and makes sleep mode pretty much useless.
cheers,
-deluxxe

First thing I would do is get CPU-Z and open that after wake-up and seeing if the CPU is running at the speed expected, or if it's stuck at some lower speed.
thanks for the reply. will try that next time it happens.

Whatever service order you have set, drag Wi-Fi either to the top (assuming it's not already there) or someplace else in the list. Click OK and then Apply. Sleep the system then wake it again to observe any changes.
2. Click Wi-Fi in the above then click Advanced. Select all the networks your computer has ever joined and delete them with the "-" button. OK then Apply again. Select your network under the AirPort icon to re-join it. Sleep and wake again to see if that did anything.
3. Try creating a new, temporary user account. Log in under that account to see if its behavior is any different.
You may have done all of these already but perhaps there is something you have not thought of. If nothing helps we may just have to wait a bit longer for Apple to release a fix.

When waking from "sleep" screen turns grey under the pointer and the computer is effectively dead. Have to hold power 'off' for five seconds to regain computer.

When waking from "sleep" the screen appears normal but, the pointer leaves a trail of grey as it moves and the whole screen will turn grey if I keep moving the pointer. The computer is effectively dead. Have to shut down by using power off for six seconds and then re-starting. I know little about computers!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

MacPro takes 1 minute+ to reconnect to LAN on wake from sleep

Hi - I am having issues with my MacPro when waking from sleep. When the machine wakes, it restarts very quickly, less than a couple of seconds. But I then get loads of error messages from open apps (mail/safari etc) that they have lost their network connection. It takes at least a minute for it to regain network connectivity.
I have other macs on the network and they reconnect immediately on wake from sleep so it can't be anything on the network itself.
The Mac pro has a mnually assigned IP address so its not waiting for ever to find the dhcp server and I have also trid connecting into a different port on the switch to make sure it is not a defective port.
Any suggestions for where I can look to resolve this?

I know for a fact, for me, that Vista and Intel Macs, and Mac Pro in particular, and from reading of the problems reported - in general on most Intel Mac owners (MacIntouch etc) that routers and modems were the cause of trouble.
Some newer cable modems included.
In some cases firmware updates helped. Some brands seemed to be "avoid if at all possible."
Maybe it is the Intel LAN - for Windows there were a lot of updates for my Mac Pro that reduced high latency and improved things somewhat.
... but I was seeing wake from sleep problems and having to use "network diagnostic" or just power cycle the modem and switches, which did work. I have NOT had to ONCE do so SINCE investing in new modem and switch. Zilch, nada, trouble-free.
Trial and error.
And yes, other Intel Macs are going to behave differently. They don't have the same Intel LAN chipset. Our hands are tied and I doubt Apple has done any real update.

[SOLVED] Problems restoring network on wake from sleep - Zbox AD04

I have some issues with restoring the wired ethernet connection when waking from sleep. Sometimes it takes 1 or 2 minutes before it comes back up and sometimes it won't work at all unless I restart (usually when it has been in sleep for hours).
The network is configured to a static IP address in rc.conf. Hardware is a Zotac Zbox AD04 (AMD Fusion E450 system) using the r8169 driver. I guess this is probably a driver issue, but I wondered if there's anything else which I could do to solve the issue. I've tried adding r8169 to SUSPEND_MODULES, but that seems to make no difference.
Another issue is that the network is "unreachable" for about 30s to a minute after booting.
Could it be a problem with my router?

I haven't really found anything much in my logs. From the kernel message log:

[ 3.457146] r8169 0000:02:00.0: eth0: link down

[ 88.123403] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 98.483350] eth0: no IPv6 routers present
It seems it took 84 seconds after initial setup for the network to come up...
Something a bit odd in errors.log:

Resolve a Wi-Fi connection issue when waking from sleep

Hi,
In the recent release for Mac OS X Lion 10.7.3 "Resolving a Wi-Fi connection issue when waking from sleep" was supposed to be resolved, not so at my end. Has anyone else encountered the same issue and if so will there be a resolve.
Thank you

Hello BGreg and thank you for your answer,
I have alreadty read about this solution, and tried it.
I downloaded the 1.2 Go file, and applied it. And repaired permissions.
Everything went fine.
Unfortunately, it didn't solve the problem.
Meaning that when iMac wakes up, it doen't join my WiFi network.
I have to do it manually.
I don't know what to do : it is very strange because I never had that problem with OS 10.7.2 !
And my network setup has never changed.
another info :
I noticed that in the network setup screen, when I want to close the little lock to restrain further modifications, it won't close. Weird !
Do you think I should call Apple Assistance ?

Won't reconnect to network when awoken from sleep
