Stream 7 Sleep Mode Kills WiFi

Ok, This is going to sound Strange but here it goes.
Got a new stream 7, connected it to my wifi (802.11 g/n). When the tablet is awake and running it works great, wireless works great, etc. When it goes to sleep however, my wifi in the house for all the other devices (Phones, other computers, wireless bridge - that were working fine when tablet was awake) all loose the wireless connection, and ability to go to the internet, and so does the tablet. When the tablet is reconnected to the wireless everything seems to work again. About the only thing i can think of is its 802.11 Power Save, but theres no way to turn that off. Furthermore, if i disable Wake on pattern match on the NIC, i loose the ability to go into sleep mode. The only hypothisis i have, is the Stream 7 is sending an 802.11 power save sleep packet (constently?) which the router dosent know what to do with and freezes the whole thing. Turning off the Wi-Fi or disconnecting the network makes the problem immedatly go away.
I have updated the BIOS on the tablet, updated the firmware on my router, Router is a Linksys E900 running DDWRT (which has no problems with any other devices), Any idea WTH is going on here? I have never seen a device do this before.

i think i got my problem figured out. It seems that it was my router - kind of. I had upgraded my router with DD-WRT, however it appears that DD-WRT does not support the "sleep" mode this tablet uses. After much troubleshooting, I was able to verify this by buying a new router; upgrading it to DD-WRT and the problem persisted. I downgraded it to the stock firmware and the problem went away. For me, this problem was especally irritating because it would bring down my wireless bridge. The bridge still occasionally drops, but it no longer appears to be related to the tablet's operation. I forgot to add that my other wi-fi devices no longer disconnect as well and their operation appears to be normal.

When in sleep mode my wifi connection keeps dropping out

Since updating to iOS 6 on my iPad 3 when I but my pad into sleep mode I loss wifi connection. When I wake the pad the wifi connection comes back.
Any help would be appreciated.

Not likely an infection at all.
Wake from sleep is usually some problematic USB or FW device.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for Sleep/Wake problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport in 10.4 & below, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Problems after sleep mode with wifi connection

I got my first iMac the other week but i keep having problems after it has gone into Sleep Mode.
Once i log back in to use my iMac again i can't seem to go online =and have lost connectivity with emails etc. Its showing that i'm still connected to my wifi and the only way to fix it is to restart.
I have already connect chat support about this and the made me reset my PRAM and reset the systems management controller (SMC)
Does anyone have any ideas??

Personally I don't let the computer sleep, I set the display to sleep. This has the same net effect and in the 8+ years I have been using OS X I have never had a problem. Set the Computer's sleep setting to Never and set the display sleep to the amount of time you had the computer sleep set at.
However if you want to try with computer sleep instead of display sleep check if the wake for network access box is checked. If it already is they your issue is likely somewhere else.

Mountain Lion sleep mode kills lan / internet connection - how to fix?

How do I fix Mountain Lion Sleep mode that cuts my Lan and nternet connection?

The problem is all the error messages on waking about lost connections - the machine re-stablishes all connections quickly and automatically but you are clicking off the error messages continually.
This never happened with Lion or earlier versions - it is unique to Mountain Lion.
There is something else going on because when I wake the computer I get no end of error messages that the connection was lost to the LAN or to the internet - obviously - in sleep mode or as it was going into sleep mode, the computor or a program like Aperature which has Facebook links was trying to stay connected.
Apple Care gave me a solution that lasted about one sleep cycle before the problem came back - they had me shut off the router/modem for about 60 seconds, had me shutdown the computor and do a System Controller reset while the computor was down. We then restarted the computor and all was fine when we put the machine into SLEEP mode and woke it up again - no error messages.
However, overnight, the machine went into sleep mode and when it woke up I had over twenty error messages about lost connections.
I get a new iMac later this week - we will see what happens with new machine.

Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.

I am Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode. I am using the Optical Out from the Apple TV to my receiver, the Apple TV is hard Wired to the Network, the IPAD is Wirelessly attached to the network (it continues to play the Audio Stream). When the Apple TV is turned back on it resumes playing once I manual select it for output from the IPAD. All device are on current releases of software. I have no Video hooked up to the Apple TV. How do I correct this?

Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

Is there any way to log off automatically from a WIFI connection every time the device is turned off or goes into sleep mode.

I have a bunch of Apple devices in my house (kids) and don't like the idea of all these devices (iPads, iPod touches, iPhones) always being connected to my home WIFI. Ideally, I would prefer the devices connect automatically when they are in use by a human and log off the network when they (the devices) go to sleep mode or are turned off.

This is not an answer, more of a question. I know that when a pad goes to sleep, it drops the connection. We all remember the thousands of posts from folks who had trouble re establishing the connection after waking up in the early days. What is different now is the use of push, and notifications. If you have these enabled, doesn't that mean that the wifi needs to stay active?
I notice that I have notifications on the screen that came in while asleep, and I can only believe that the wifi saw them. This is different from the old behavior or re grabbing the wifi.
So, to Pam, on one the devices you are concerned about, turn off notifications, fetch and push, put it to sleep, and see if it drops off the network. I am kind of curious.
By the way, having the wifi active has not shown me any battery usage. The router certainly does not care. Security is at the router end, so if somebody wants to hijack my signal, it does not matter if the pad is active or not. So I guess I am not clear either on what your issue might be.

IOS 4.2 killing iPad battery in sleep mode

I noticed the battery in my Touch was dropping overnight after upgrading to 4.0. I have been turning off the Wi-Fi when I am not using it and it has been holding a charge.
I just upgraded both my wife's and my iPads to 4.2. We are both experiencing problems with battery drain while in sleep mode. I charged my iPad to 100% then let it sleep for four hours. When I powered it back on it was at 96%. Without using it, I checked again in two hours and it was at 94%. My wife's iPad is the same. I turned off the Wi-Fi and will check again in a couple of hours to see if it is still falling. It's obvious that something in the new iOS is continuing to draw a lot of power while in sleep mode. That would suck if I had to remember to turn off the Wi-Fi and 3G every time I stop using my iPad. Anyone else seeing the same problems with their iPad's and iPod Touch's?

I have experienced the same problem. Since I have upgraded my iPhone and iPad two days ago the battery in both devices drains rapidly. Last night at 10 p.m. The iPad was fully loaded with all applications shut down. I didn't touch it until 10 a.m.the next morning and the battery was down to 62%. Before the update it would have been still out 100%. It's practically the same with my iPhone. It takes just a little bit more than half a day for the battery to be below 20%. In addition the navigation system on the iPhone shuts down frequently and it is does not take new calendar entries. A lesser problem is the fact that opening the calendar takes very much longer than usual. All these problems coincide with the update and as it happens to be on different devices I am most certain that the new software is the problem. I can only hope that Apple will very quickly solve these problems.

Wifi disconnects when waking from sleep mode; running Mountain Lion

Had this same issue with Lion as well,, wifi disconnects when waking from sleep mode,,,any ideas how to fix this pesky issue?

Hi Sky,
This has worked for a few...
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
10.7…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
208.67.222.222
208.67.220.220
Click OK.
Also, turn off IPv6:
System Preferences » Network » AirPort » TCP/IP tab » Configure IPv6
Or whatever Interface you use.

Wifi problems in Mountain Lion when resuming from sleep mode.

I have recently upgraded my Macbook Pro to OS X Mountain Lion. I have been noticing that everytime my computer enters sleep mode and I wake it back up to use again the wifi connection is lost or frozen. If I roll over the wifi bars at the top of my desktop the rainbow wheel appears over my toolbar and I cannot access the internet. The only way I have found to fix this problem is to restart my computer and connect to the internet or use a program or set the energy settings to prevent the computer from falling asleep. This problem has really been agravating me for the past couple of weeks. Has anyone experienced a similar problem or found a permanent solution?

Ok, so it's certainly a Broadcom wifi adapter. The Lenovo nomenclature refers to it as "1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter (43142)". But why are you trying to install Realtek drivers?
The only driver I could find is this one, for Windows 8. Please uninstall all other drivers, reboot and install this one, or let Windows find a suitable driver and see if that works. Also please read the document from the link, it gives detailed instructions on installation and uninstallation, how to check version number etc.
It might be the case that you have to wait a bit for an updated driver for win 8.1 to resolve the problem, but It doesn't hurt if we try to find a solution.

Wifi/System Preferences Freezes After Waking From Sleep Mode.

Every since I installed Mountain Lion, I've had the issue of my MacBook Pro freezing up while it checks for Wifi after waking up from sleep mode. I have to constantly restart my computer. I'm wondering if Apple is aware of this happening on other computers and not just mine.
Also, my laptop is considerably slower since installing the OS update, especially when I turn on my computer.
- Rog

!!!!!!!!!!!So far only this has worked for me!!!!!!!!!!!!!!!!
Go to System Preferences -> Energy Saver -> and UNcheck the box that says "Put hard disk(s) to sleep when possible on BOTH the Battery and Power Adaptor tabs.
I had this issue when I first installed Mountion Lion on my Aluminum MB 2008. Thought it was 10.8 so I down graded to 10.7 Lion, issue still happened. But after I applied this setting the issue seemed to go away. Before this I also deleted the old wifi settings in Network Utilities and added the Wifi device, ssid, and wep key again (not using WPA2). I will continue testing through the night and will update once I can determine the issue is gone.
Hopefully this works for others too.

OS X Mavericks v10.9.4 Update still does not fix the wifi shut off in sleep mode problem

OS X Mavericks v10.9.4 Update was supposed to fix the wifi connectivity problem with my iMac. Wifi disconnects in sleep mode and does not connect when awakened. Must reconnect manually every time. PITA.

Your observation is correct about wifi disconnection in sleep mode. That is normal, you may want to check to see if your Mac supports Power Nap/is enabled- OS X: About Power Nap
The reconnect should be automatic within a few seconds.
Does it happen with multiple wifi networks or just one?
Have you tried deleting and re-adding the wifi network?

I have an iMac (Mid 2010) and am running 0sx 10.8.5 and the WiFi always loses connection during sleep mode. I have seen numerous different solutions none of which seem to work. Can anyone help?

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
          Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
          Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. This step shouldn't be necessary, but has been advised by Apple Support in some cases, apparently as a workaround for a bug. Open the Energy Saver pane in System Preferences. If applicable, click the padlock icon in the lower left corner to unlock the settings. Enter your administrator login password when prompted.
Select the Power Adapter tab and uncheck the boxes marked
          Wake for Wi-Fi network access
and
          Enable Power Nap...
if present. Then, if the computer is a MacBook, select the Battery tab and uncheck
          Enable Power Nap...
11. Reinstall OS X.
