My iPad loses connection after waking away from router even in the next room over.

I know it's just my iPad, as when other people with iPads are here (or even just with my iPhone), they still have their connection and mine is lost. Or when I go places, people will have their connection pretty far away from their router and my connection is lost. I have rebooted the iPad and nothing. My iPad screen cracked previously so I took it someplace to get it fixed, so I don't know if that has anything to deal with it? Help please!?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Apple TV loses WiFi Connectively After waking up from sleep

My Apple TV, software version 3.0.2 (which gives us 1080P btw), works fine, until I put it to "sleep." Later, when I use the Apple TV, it says: "Not connected to the Internet." In effect, my wifi has disappeared from the memory of the Apple TV, and I have to enter the wifi network's password again on the Apple TV.
I have had this Apple TV for about a year; the problem appeared maybe one month ago.
I took it to the Apple Store after Apple Care Telephone Support consulted with engineers. The Apple engineers said it could be a hardware problem, and for me to bring my Apple TV to the Apple Store so they could diagnose it. But at the Genius bar, they put it to sleep and woke it up and it never lost connectivity every time. I suggested that as the Apple Engineers wanted the hardware looked at, why doesn't the Apple Store keep my unit, put it to sleep, and wake it the next business day? The genius bar refused, as the problem did not replicate itself at the genius bar. I told them that trying after 10 minutes wasn't enough. They should try it overnight, as I do (go to bed, try it the next day, only to discover that the Apple TV lost it's connection to the WiFi.
So for now, my work-a-round is that after a few hours, I have to reenter the password for the wifi. I've been reading threads about similar issues with the iPad, but I don't know if the problems are related (technology wise).
Bottom line: My Apple TV loses its connectivity after being in sleep mode for awhile. Nothing to do with the iTunes store or 3.0.2 as far as I can determine; if I don't put it to sleep I don't lose connectivity.

Thank you, Jamie Cox1. However, after rebooting the Apple TV, I lose my 1080P; it goes to 720P and takes about 5 minutes or so to reboot. Then I have to set the 1080P again. The good news is that the wifi returns But it is quicker merely to re-enter my password.
The problem remains: After a while of having the Apple TV in sleep mode, I lose connectivity to my wifi And while I have a complicated password (upper and lower case letters, numbers, and not a dictionary word), it still is quicker to re-enter my password than to wait for the Apple TV to reboot and re-enter the settings for 1080P.
Thanks anyway; if I only had 720P perhaps this solution might be enough - but I have 1080P.
I am working with Apple Care; I have reconfigured my wifi twice with Airport Utility, removed all interference (microwaves, cordless phones), and still the problem remains. Apple Care hasn't solved the problem. The Genius Bar at the Apple Store hasn't solved the problem. Re-booting does find the wifi again, but it takes a long time, and then I still have to re-set the resolution to 1080P. So I just re-enter my password each time.
And that's my update! I appreciate everyone's suggestions. However, the problem remains: after putting the Apple TV in sleep mode, and then later when I want to use the Apple TV, the Apple TV forgets that it is connected to wifi and I have to re-enter my password, or I can take some time and reboot the Apple TV but then while the wifi returns, the 1080P disappears.
Thank you everyone for all your suggestions
But the problem remains

Problems with wi-fi connection after waking up from sleep

Hey,
I have MacBook Pro 13 (early 2011), MacOsX 10.7.2.
I've got a problem - when I wake up after sleep my internet connection doesn't work for half a minute, may be more. I do diagnostics and it says that connection is ok, but still don't work. I've tried to do something with energy saving settings, but i didn't success.
What is important: I didn't have such a problem previously. I think it appeared after one of software updates. I can even remember, there was an updated with description, saying that t fixes the problem of internet connections after Mac wakes up after sleep...
How can I solve this problem?

I have the same exact problem and it is caused by the latest ETI or whatever update it is. - the one that required restart of my computer. For me it takes multiple times to turn wifi on and off on my macbook pro before the internet starts working. Someone please help. Apparently reinstalling Mac Os X 10.7.2. should help but I'm not sure if I want to drop my mbp at apple store for 2 days yet again.

AirPort drops connection after waking up from sleep?

Hi, this situation only occurs on my university campus. My university has a 802.11b wireless network. It makes up about 28 hotspots blanketing the entire main campus, it has a 128bit WEP encryption 26hex and a proxy.
If I attempt to connect the first time, I would get connected. Once I put it to sleep then wake it up, it loses the connection and I would not be able to reconnect (while being bombarded with the error message, "There was an error joining the AirPort name 'xxxxx'") until approximately one hour has passed.
All troubleshooting steps have been tried (deleting p.list files, caches, keychains, reseting AirPort, reseting PMU and PRAM, reformatting HD, you name it, it's been done by my university's computer staff and by a Genius).
I'm currently frustrated not only I can't resolve this issue, but there's finger-pointing from both sides (Apple Genius blaming my Temple Univ wireless network, then Temple blaming on my AirPort's drivers/hardware) and there's nothing conclusive I can prove to both sides (not to mention my MacBook is only 1 week old and only 2 people including me have reported this issue at Temple). I have done one experiment to show that my home Linksys router with 128bit WEP encryption works flawlessly and to testify saying that the previous Core Duo MacBook I had work flawlessly with the Temple wireless network.
Any suggestions?

Welcome to the Apple Discussions!
This may not actually "solve" the problem, but it may help you bypass it. On my MacBook, I have a network location called "No Networking". I use this location in between some other networks when I have trouble switching (for example, I can switch from my home AirPort network location to my work Ethernet location without any problems, but I can't seem to go the other direction). The "No Networking" location has ALL of the network ports disabled. This is also helpful if you're on an airplane or somewhere you know you won't be using the network because the AirPort card and the Ethernet port actually use battery power to run if you're not plugged into the AC power. So, turning off the ports saves you a few minutes on battery power. So, when I arrive at home, I switch from my "Work Ethernet" location to my "No Networking" location, pause for a couple of seconds and then select my "Home AirPort" location and everything seems to be fine.
To do this, open the Network System Preferences and use the "Location" pop-up menu to create a "New Location". Give your new location a name like "No Networking". Then select "Network Port Configuration" from the "Show" pop-up menu. Uncheck every port and click the "Apply Now" button.
I have a different network location for each of my possible networking options I encounter. When I have trouble moving between two, I just select the "No Networking" location from the Apple menu and then I select the right network. See if that doesn't help some.

IMac OSX Lion 10.7.4 loses Wifi after waking up from sleep

So basically just like my title states, when my computer wakes up from sleep about 70% of the time the internet will not work. My mac does see and connect to my network, but something isn't being sent as I have no connection when trying to surf the web. I then reset my modem and router, and it still doesn't work. What fixes my problem is a reboot or Logging out and back in. I don't know why that does the trick but it does. I have looked at http://support.apple.com/kb/DL1501, however this update is only for 10.7.3. Is there something I can do to fix this problem?
As a side note, if I have Parallels Desktop running my iMac's wifi after sleep will not work, but it will work in the Windows 7 parallel. Why is this?

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.

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.

Lose connection to external USB hard drive after waking up from sleep

My Mac lost connection to the external USB hard drive after waking up from sleep. I can still see the folders in the hard drive in Finders, but when I double clip a folder no file within the folder is displayed. I have to reconnect the hard drive with iMac to read its contents.
May I ask how this happens and is there a solution?
I'm using Paragon NTFS for Mac OS X to read from and write to NTFS format of USB external hard drive.
Thanks!

... I un-ticked the "put hard disks to sleep when possible" option in the Energy Saver panel in the System Preferences, and it seems the problem is solved. will have to sleep and wake up my iMac to further verify if this is the solution ...
Alternative advices are always greatly appreciated!

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..

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.

Ethernet interface disappears after waking up from sleep

Hi guys,
I've been trying to debug a networking problem without any luck and I think it's about time I ask the forum for help.
My ethernet interface no longer works after I wake up my computer from sleep. I have no idea why.
Before sleep:
# ls /sys/class/net
lo wlp2s0 enp3s0f2
After waking up from sleep,
ls /sys/class/net
lo wlp2s0
Here are the list of services I have running.

Furthermore, plugging in the ethernet cord after the computer has started doesn't connect to the internet, even when I have the ifplugd service running. I am forced to run:
sudo ip link set enp3s0f2 up
sudo dhcpcd enp3s0f2
However, I can't run these commands after the laptop wakes up from sleep since it no longer sees the ethernet interface.
I am thoroughly confused. Please help me.

It seems to be fixed after the kernel update. On an related note, I've switched from using dhcpcd to netctl. I've enabled netctl to automatically connect to the network using:
# systemctl enable [email protected]
# systemctl enable [email protected]
So when I check for the status of the ethernet profile, I get told that's it's inactive.
#netctl status ethernet-dhcp
netctl@ethernet\x2ddhcp.service - Networking for netctl profile ethernet-dhcp
Loaded: loaded (/usr/lib/systemd/system/[email protected]; static)
Active: inactive (dead)
Docs: man:netctl.profile(5)
But I turned off the wireless, so I must be connected to the ethernet, So how do I know which profile I'm connected to?

W510 eSATA/USB2.0 combo port does not respond after waking up from sleep mode

Has anyone tried to connect external DVD/CD player or burner to the eSATA/USB combo port and experienced very slow system performance after waking up from sleep mode? It might takes minutes to launch an application program that usually takes just few seconds. My W510 can not even restart. It will just stop at the Thinkpad logo if I tried to restart after waking up from sleep.
The funny thing is if I moved the external DVD/CD player to the USB2.0 port in the back, everything went back to normal. I don't know if this has anything to do with the fact that the combo port has something to do with eSATA.
Thanks

It seems that this problem is unique to my system. I am hoping that one of the Mac Guru's will have at least a pointer in the right direction.
Thanks.

Hi,
I have almost the same problem with my T540p, except that there is no internet connection not only after waking up from the sleep mode, but also when starting windows and sometimes the internet connection will get suddenly lost during normal windows run.
I tried installing all kinds of drivers - latest from intel, latest from lenovo update (which is always different version from the one from intel), some older versions. Nothing helps.
Re-enabling the WiFi device like Aaziz1982 suggested, doesn't help.
Here is a more detailed description of my problem: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T540p-WiFi-Connected-no-internet/m-p/177818...

Hello, I have a macbook pro late 2011 15 inch with 4 gb ram. My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Is there a fix?

My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

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 the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
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. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
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? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Bridge loses connection after a few minutes

Hi at all,
my name is Daniel and i have a problem with two AIR-SAP1532E-E-K9 with the software version 15.2(4)JB3b.
The situation: Our customer want to connect two buildings with a wireless bridge, so he bought two 1532 with two AIR-ANT5114P2M-N= antennas.
Over the wireless connection should go traffic from different VLANs.
The root bridge is configured as follows:
dot11 ssid [SSID]
   vlan 212
   authentication open
   authentication key-management wpa
   infrastructure-ssid
   wpa-psk ascii 7 [KEY]
interface Dot11Radio1
no ip address
no ip route-cache
encryption vlan 212 mode ciphers aes-ccm
ssid [SSID]
antenna gain 14
peakdetect
no dfs band block
power local 15
packet retries 64 drop-packet
channel dfs
station-role root bridge
interface Dot11Radio1.204
encapsulation dot1Q 204
no ip route-cache
logging event subif-link-status
bridge-group 2
bridge-group 2 spanning-disabled
interface Dot11Radio1.212
encapsulation dot1Q 212 native
no ip route-cache
logging event subif-link-status
bridge-group 1
bridge-group 1 spanning-disabled
interface Dot11Radio1.463
encapsulation dot1Q 463
no ip route-cache
logging event subif-link-status
bridge-group 3
bridge-group 3 spanning-disabled
The GigabitEthernet is configured like the dot11radio 1 with the Sub interfaces for each VLAN.
The non-root bridge is configured as follows:
dot11 ssid [SSID]
   vlan 212
   authentication open
   authentication key-management wpa
   infrastructure-ssid
   wpa-psk ascii 7 [Key]
interface Dot11Radio1
no ip address
no ip route-cache
encryption vlan 212 mode ciphers aes-ccm
ssid [SSID]
antenna gain 14
peakdetect
power local 11
packet retries 64 drop-packet
station-role non-root bridge
interface Dot11Radio1.204
encapsulation dot1Q 204
no ip route-cache
logging event subif-link-status
bridge-group 2
bridge-group 2 spanning-disabled
interface Dot11Radio1.212
encapsulation dot1Q 212 native
no ip route-cache
logging event subif-link-status
bridge-group 1
bridge-group 1 spanning-disabled
The GigabitEthernet is configured like the dot11radio 1 with one subinterface for each VLAN.
At the moment the non-root bridge connects to the root. All is fine and each subinterface comes up. After 3-4 minutes the non-root logs the message that there is no response from the root and shut down the interfaces and after a short moment the non-root connect to the root again.
The root shows with the command sh dot11 associations:
802.11 Client Stations on Dot11Radio1:

So it looks like the root bridge shuts the interfaces and then activate them after a short time.
What i want to do next is to upgrade the software version and to set the channel of the 5 GHz interface manually.
I hope somebady have another idea and would share it with us.

Daniel

Hi Daniel,
Thanks for your brief explanation, the configuration looks good and from the logs I see that the radios are going up and down.
Kindly, make sure that the antennas are installed and mounted in the right direction.
Change the channels manually, you are using Radio 1 for bridging make sure there is enough coverage to cover Radio 1.
You can also test with Radio 0 for bridging and i also understand that there are some of the known issues with the version you are running for bridging and WGB connectivity.
Once after doing all these tests it's good for you to upgrade the APs to 15.2(4)JB5 and above.
