Network connection after waking from sleep

Hi... More or less any time I allow my MacBook Pro to go to sleep, when I wake it up I am nearly always disconnected from my Airport connection (I connect to a NetGear wireless router via my internal Airport card). I go up to the menu bar and click on the now grey airport icon and I do still see my network in the list of available networks. I click on it, after several seconds a message comes up that says "there was an error joining the Airport network "network name""... But I then simply click on OK (rather than Try Again, I've learned that by trial and error) and the network reconnects just fine... Then when I let the machine sleep again at some later time, I do that all again... Any suggestions of what might be going on??? I do have "Use Interference Robustness" turned on (not that I know why exactly) but I've also had it off before and that seems not to matter... Any suggestions??? thanks... bob..

I have "join preferred networks" selected, and mine os the only one on the list, and it still does not connect after waking from sleep. It is WEP security, not WPA2. I checked out the following article, but it was of no help:

IMac loses WiFi connection after waking from sleep on OSX 10.8.2

Bought a new mid-2011 21.5 inch IMac this week. It is not re-establishing WiFi connection after waking from sleep. Was happening on OSX 10.7 that it came with, so updated to 10.8.2 and same problem exists.
I am running a mid 2012 MacBook Pro with Retina Display alongside, on OSX 10.8.2 and no problems at all. Cannot work out what is causing the IMac to fail and neither can Apple!
Could it be the Netgear Wireless Router 3 years old? Full signal strength!

Me too!
I am on a MAC Pro desktop and I am having the same issues. I go to system preferences and just click the network icon. Then I close mail and when it opens it now sees the network. This is getting very annnoying.

No connection after waking from sleep using Express as base station

I find it difficult to re-establish my Internet connection after waking from sleep.
The Airport Express is connected to a wired Linksys router. I am using the Airport Express as my main base station. The Powerbook is joining my preferred network, but I am unable to get any in- or outbound Internet traffic.
I am, however, able to connect to my Linkys and login to to its admin area. When I run Ping and Traceroute diagnostics from the Linksys web interface, everything seems to be fine-- I am able to see outside servers. So the problem is this-- I am losing my Internet connection somewhere between the Linksys router and my Powerbook. Only after I fiddle I reset the Airport Express and fiddle with the Airport menu (Turn Airport On/Off) am I finally able to get out to the Internet.
I have the channel switching set to Automatic, but I've also tried running the Airport Express at different channels to no avail.
Has anyone experienced similar problems?

Since you have an Airport Express connected to a separate router, start by disabling the router built into the Airport Express. To do this - run the Airport Admin Utility, select your Airport Express, click Configure, click the Network tab, and uncheck the setting to "Distribute IP addresses". Update settings to the Airport Express. Then - very important - restart all wireless computers.

MBA loses internet connection after waking from sleep

I have a new Macbook Air running Mavericks and new 802.11ac Airport Extreme router.
My problem is that the MBA drops the internet connection after waking from sleep. I tried the solution offered by the OP, but it didn't work.
In my case, here's what I have to do to get a connection again. I open the Network preference pane, and then choose "Assist me..." and then "Diagnostics". Invariably it will show a green light beside Wi-Fi, Wi-Fi Settings and Network Settings. I have 5 bars showing in the WiFi menu bar icon. But ISP, Internet and Server will be yellow.
When I go through the steps prompted by the wizard, the ISP/Internet/Server lights turn green on the third screen where I select the wireless network I want to join.
It seems as if it's connecting to the WiFi network when it wakes from sleep, but losing the internet connection?
Note: I have a new iMac as well running Mavericks and don't have this problem with it.

Ethernet slow to connect after waking from sleep

Since installing Lion (and updating to 10.7.1) on my 2008 24" iMac I have noticed that after waking from sleep the internet connection takes about 10 seconds to restore. I have reset the SMC and PRAM and performed a safe boot (in case this helped) but to no avail. The slow conenction can be observed if after waking from sleep the Network System Preference is clicked and the ethernet status "light" is red, changes briefly to amber and then green indcating a connection. The iMac is connected via an ethernet cable to a Linksys 802.11n 4 port wireless router.
I also have a 2010 13" MacBook Pro, with the same OS, and version, conencted in the same way to the same Linksys router and it does not exhibit this problem.
This slow internet connection access after waking from sleep is an annoyance and I'd appreciate any input on how to elimnate it.
Thanks to those wiser than I, who might read this note.

SOLUTION FOUND!
I've found a list of possible solutions here's the link:

I solved my problem moving the Ethernet and WiFi adapters in the top of the list and Bluetooth at the end.

Losing WiFi connection after waking from sleep

I've iMac 27 in. with recently upgraded OS X Lion to 10.7.4. After this was done the problems strated with connecting to Wi-Fi through my Time Capsule (2TB, 802.11n 4th Gen) after waking from sleep. Everything works fine when iMac is started after shutdown. My internet router is connected through ethernet cable to Time Capsule and iMac is using Wi-Fi connection with Time Capsule.
I've tried to install iMac Wi-Fi update v1.0 but it I cann't do it because my OS X is 10.7.4 and the update installer is stopping the installation after the check of my OS version.
Could anybody help to solve this problem, please?

but when the
computer goes to sleep and is then awakened, there
are no wireless networks listed in chooser... like
there are no wireless networks available...
Hi greaser5!
That is definitely NOT typical operation. Yes, your Core Duo iMac must restart after sleep, but It should reconnect to a working network instantaneously (less than a second), although it will probably take longer than that for your iMac to fully restart after sleep and actually be able to use the network.
Delete all prior wireless configurations that you have saved on the "Location:" selector of the Network panel of System Preferences. On the Network>AirPort>AirPort panel also delete all your preferred wireless networks. Click the "Apply Now" button.
Restart your Mac. Turn on AirPort. Use the Network panel's "Assist me..." button and the following blue "Assistant..." button to configure a fresh wireless connection to your working wireless network. This will be fresh and total, just as you did when your iMac was new. There is no need to give your network either a new name or a new password, as the old ones will work just fine in the new configuration, since as you know, the current network is working fine, the iMac simply can no longer connect to it correctly using its current configuration.
I have not been able to test the above on a Core 2 Duo, so do not know first hand if it will make any difference on those iMacs, but that or some similar fiddling should resolve the issue.

No Wi-Fi Connection after waking from sleep.

I keep having a problem of my MBP not reconnecting to Wi-Fi if my computer come out of sleep. The network connection shows up in my list, and when attempting to connect I recieve an error.
The only remedy is to reboot OS X, and then the computer automatically logins into the Wi-Fi connection.
Why is this?
It is very annoying if I leave my computer for a few minutes and return to continue using the internet and such, and I have to reboot my computer.
Thanks

If your using WPA try setting your WPA Timeout to 365 days. Seems to have stopped my disconnects waking from sleep.

MBA not connecting to network drives after waking from sleep

I have been having this problem over the past few days. When my lat 2010 MBA wakes from sleep it will not connect to my NAS. If I try to force it too connect finder will crash and I get the cannot find finder.app error -10801. The only way I have been able to get the MBA working is a hard reset. Then all is well until I close the lid and wake it up at some point.
I was thinking about re-loading SL, but thought I would check here for any thoughts on this problem.
Thanks

Hi Carl,
This will fix many problems AND clean up a lot of useless stuff.
Get Applejack...

After installing, boot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
One other "Wake" problem... ignore the HW and other symptims because it works in many other situations...

Mail won't connect after waking from sleep

5K display iMac running Yosemite 10.2.2: When I first boot my iMac mail works perfectly as does the rest of my internet connection. I am using Ethernet directly connected to the router, but the same thing will happen if I use the wifi connection. Router is directly connected to the cable modem.
If I put the iMac to sleep and come back the next morning: I will see new messages available in my gmail and other accounts that have loaded during the night. If I hit the "get new messages" button, sometimes it will get the initial group of messages (IMAP) and move them into the POP gmail account, but most of the time mail will just fail to make a connection. The connection doctor will tell me that I'm not connecting to the internet. However, if I go to Safari or any other internet app, I have no trouble connecting.
Then, somewhere between 30 minutes and 2 hours after waking the iMac it magically connects - until the next time I put the iMac to sleep. Quitting and restarting Mail makes no difference. I have already deleted Sophos and anything else that others seemed to suggest would cause a problem. I have no trouble seeing anything in the mbox messages stored on the iMac. I just can't send or receive mail until it comes back to life.
Suggestions are gratefully appreciated.

I don't yet have Q2007, waiting for first patch to show up, but I would look for a conflict with other programs or background processes, lack of RAM, or whether you migrated some PPC application or libraries.
I see that Quicken 2006 got an update Sept. 9th.
One of the fixes in the Q2006 R5 patch:
Stability improvements were made to prevent Quicken from quitting unexpectedly when launching with certain internal files corrupted.
I would reinstall Quicken.
Rosetta:
I know it runs PPC, but if someone didn't tell me that PPC apps run under Rosetta, I would not know it was there (it isn't a listed process, and you can't choose whether to use Rosetta or not, like choosing between Preview and Acrobat). Only because under Get Info: Kind: Application (PPC) - and you would have to know that equates to Rosetta.
So you're sure it is working fine in Rosetta... I read 10.4.8 is suppose to improve Rosetta...
The best way to improve Rosetta is to have 2GB RAM.

No airport connection after waking from sleep

Hi,
I recently upgraded to 10.4.11 from 10.3.9 and now whenever I wake my Powerbook from sleep I lose my wireless connection. I can restore the connection by going up to the menu bar and turning Airport Off and then back on. However, I am looking for a permanent fix.
I have searched this forum and found no solutions which fix this problem.
JP

Okay. I found a solution and thought I would share.
I needed to go into the Network Preference pane and select "Edit Locations" from the "Location" pop-up menu. I then deleted the "Automatic" location and made a new location I named "Home" and all is well again!
So again, if you experience the problem I originally posted about after upgrading or updating your OS, try creating a new "location" in the Network Preference pane. I found it was pretty easy and I didn't even need to re-enter the Airport network info or password. I just double-clicked my home network from a list of networks which appeared when creating the new location.
Cheers!

13"w/ext display loses WiFi connection after waking from sleep

I have my 13" macbook pro (mid-2009) connected to an external monitor. When the system goes to sleep and wakes up, the wifi is disconnected and an error window pops up saying something to the effect of another computer is using the IP address assigned to my computer.
If I reset the modem it usually works, otherwise I must wait about 15 minutes for system to connect again.
It does not happen if there is no monitor connected to the notebook.
Is there something I can do to stop this from happening?

I have a strong suspicion that I am getting wifi interference from my neighbors. Several new wifi signals have appeared in the last month coinciding with new neighbors moving in and some old ones getting wifi. Upstairs, I can pull up 6 or 7 networks, some broadcasting on the same channel. Downstairs, where my MacPro resides, I do not see those networks. My problem seems to manifest itself on my MacBook Pro when I move upstairs and can pick up the extra networks.
When I power cycled my router this morning, I noticed it changed channels from 11 to 6, indicating that the Auto setting is determining a better channel. Also, this problem seems worse after 5 pm. So, I'm chalking this one up to neighbor interference. If my iPhones could use the 5 GHz band, I'd use that exclusively... or maybe it's time for a simultaneous dual band router.
I wish I had a dollar for every time I've advised a customer that interference was the cause of his wireless connectivity issue.

Network problem after waking from sleep

I have a home network. All of the computers are Win XP except this Macbook. I have them all networked through a Workgroup which works just fine. The mac has no problems finding and connecting to the Windows computers but frequently after putting the Mac to sleep and then waking it up it no longer connects to the windows work stations unless I turn Airport off and then turn it back on..
It shouldnt be like this..any way of fixing it?

Same here on an older iMac since Lion. Thanks for the uncheck wake for network access tip though, it doesn't do it either in that case, I will leave it that way.

Lose broadband connection after waking from sleep

I use Power Mac G5 OSX10.3.9 to connect to the internet, via Sky Broadband (in the UK) and Netgear DG834GT modem with ethernet cable (not wireless). I can connect with no problem and everything is fine, as long as I keep my G5 on or shut it down completely and turn it back on again later. However, if I put it to sleep for more than half an hour, then, when I wake it up, I lose broadband connection. The connection is still alive for a few seconds after I wake up, and other computers connected to the same modem can connect AS LONG AS THE G5 IS STILL ASLEEP. But it appears that the act of G5 trying to connect back to the internet kills the connection. Rebooting G5 doesn't help. The only thing I can do to reconnect once I lose it is to reboot the modem (by turning it off and turning it back on).
I cannot determine whether this is a problem with the modem or with the G5. Any idea? Thanks.

I quite serendipitously discovered what was causing the problem and how to stop it, although it's not a solution per se. I am explaining what I discovered in detail below in the hope that it might help future users who might encounter the same problem.
When you log on to http://192.168.0.1, you are connected to the Netgear DG834GT router itself (after typing in the username and password). On the "router status" page, there is a button called "show statistics." If you click on this, you open a window with a running display of statistics on the phone line, like upstream and downstream noise margins and line attenuation. The line is scanned every 10 seconds to give updated information in real time.
I always had this page open on my desktop, because I was having problems with line noise and wanted to know the current status of the line and its noise margin at all times. When the noise margin was low, my connection speed was incredibly slow.
I discovered that it was the "show statistics" page open that cause the loss of connection when I wake up the computer. If I don't have the "show statistics" page open, I don't lose the connection when I put G5 to sleep and then wake it up.
I tried it with different browsers and discovered that Safari and Netscape do not have the same problem. I do not lose connection even if I have the "show statistics" page open in Safari or Netscape. It only happens with Firefox (which I usually use) and Mozilla. If I have the "show statistics" page open either in Firefox or Mozilla, then I ALWAYS lose the internet connection when I wake up the computer.
This is not a true solution in the sense that I don't know why this happens or how not to lose connection when the "show statistics" page is open. But at least now I know not to have the window open.
