Lost internet connection randomly and after sleep

Hey guys,
So I bought my apple TV2 refurb a couple weeks ago, and I've had a recurring problem since. I've restored multiple times to no avail.
So I'll be streaming something, Netflix mainly, and then at random time intervals (sometimes its 5 mins, sometimes 15 or more) I'll lose internet connectivity, the stream will stop. When I go to settings->network it still says that it is connected to my router with full signal strength (but there's no connectivity if I click on the itunes store or netflix).
The same symptoms happen whenever I wake from sleep. Then if I reboot the apple TV2 (hold menu and down) and it restarts it will be connected to the internet until it loses it again.
It is VERY frustrating.
Any help guys?
Using a Netgear WR2000 N-router that works flawlessly with my iMac, 4 MacBooks, PC netbook and PC laptop all over my house.

Try another wifi channel or two to eliminate the possibility of interference.

Loss of Internet connection through TC after sleep.

I have a Netgear ADSL Wireless modem which is connected to a TC in bridge mode.
So here is what happens, I am connected wirelessly to the TC and can access the internet no problem. I then put the MacBook Pro to sleep, then on waking the MacBook I have no internet connection. But if I select the wireless network of the Netgear I do have an internet connection. The MacBook then at some point reverts back to the TC wireless network and all works OK. I think it reverts back to the TC network after a sleep period.
It does not do this every time but it does it enough to have become annoying.
I presume that on those occasions that I have no internet connection through the TC that this is because the TC is otherwise occupied?
Is there a way to cure this problem?

Hi Larry,
If you go to Control Panel -> Network Connections (For Vista and Windows 7: Network and Sharing Center) -> Double click on your Network Adaptor (Vista and 7: Top left hand corner of the Network and Sharing Center, click on 'Change Adaptor Settings' and double click on your adaptor. Click Properties and scroll down to 'Internet Protocol Version 4 (TCP /IPv4), click Properties and make sure that 'Obtain an IP Address automatically' and Obtain DNS server address automatically' are ticked. Click Ok, then OK, then finally close. Check to see if you have connectivity. If you don't, go to start, in Run (Or in the search bar) type 'cmd'. Once Command Prompt opens, type 'ipconfig /flushdns'. Close Command Prompt and check again. If you still don't have Internet connectivity, go to Internet explorer and click Tools -> Internet Options (If you have Internet Explorer 7 or 8, press Alt before looking for tools. This will make the bar appear). Go to the Connections Tab and click on 'Lan Settings'. Make sure that you do not have 'Use a proxy server for your LAN' ticked. Also make sure that you have 'Automatically Detect Settings' ticked. Once you have done this, click Ok, Apply and Ok and check again for connectivity. If this didn't resolve your problem please post back
Sorry for the long answer
Cheers

Lost internet connection on desktop after installing windows 10

Updated from windows 7 to windows 10 and I lost my internet connection. My connection is good, wires, router all good. Windows 10 seems to be working great except for no internet. It say's "not connected-no connections are available". So is it not reconizing the broadban card builted into the board or what. I tried reloading drivers. I can use any help I can get. I have a hp compaq dc5100 sff with 3ghz, 2gb ram desktop. I updated my laptop and it works great. If I can't get it figured out, I guess I'll go back to windows 7. Any ideals, let me know................

Unfortunately the Acer support site does not list Windows 10 drivers for this model. So you'll need to determine what brand/model of WIFI hardware is inside. You could give the Acer vendor detection tool a try: http://global-download.acer.com/SupportFiles/Files/HWID/APP/HWVendorDetection.exe#_ga=1.118719882.244183942.1440066583If you can find brand/model of the WIFI hardware, you could do a Google search (or check the manufacturer site directly) for an updated device driver for Windows 10. If you can find one, uninstall the old device driver from the device manager and install the new one. Hope this helps, good luck.

Just purchased Airport Extreme ac and lost internet connection 3X. Reset to factory settings and worked for 2 days then lost connection and remedied by unplugging power supply. Anyone else having problems?

Just purchased Airport Extreme ac and lost internet connection 3X in less than one week. Fisrt time, reset to factory settings and fixed problem. Has occurred 2 additional times and connection re-established by unplugging AP extreme. Anyone else having these problems? Do I have a bad router? Thanks.

I definitely think this is a Mavericks issue. My iMac running Mavericks is the ONLY system in the house that drops the network randomly while all other systems never lose the network. No idea how to resolve this, but here is the workaround I'm posting:
I've had the 'network drop' issue with my Airport Extreme for the last 2 months. It reconnects when I pull the ethernet cable and plug it back in. I've tried downgrading the AE firmware, resetting to factory, etc. Nothing worked. I finally threw in the towel and created a script that monitors my network connectivity and restarts my interface if it senses it has dropped:
#!/bin/ksh
while true
do
yup=`ping -c1 -t2 www.google.com|grep from`
if [[ -n $yup ]]
     then echo "Internet is connected!"
else
        ifconfig en0 down; ifconfig en0 up
        echo "Down at `date +%m%d%Y%H%M%S`">>./dropped.out
fi
sleep 5
clear
done
I know its a workaround, but its saving me the headache of constantly pulling my cable and putting it back in!
Good luck!

Lost internet connection while restoring iphone 4S from backup after iOS 6

Hi everyone..
I have just updated my iPhone 4S to iOS6 yesterday. It was iOS5.1.1 and was in jailbreak mode before the update.
I did sync my iphone and did the 'Backup' as well before the update by using my latest iTunes via my laptop.
The iOS6 update was successful.
However, the 'Restore from backup' failed.. many times!! Everytime I tried to Restore from backup, i lost internet connection towards the end of the 'restore in progress' process so it was never complete. I had to pull out the iphone cable or restart my pc every single time that happened. Because i cannot get an internet connection after that happened. I cannot connect to any wireless network, so I had to restart the pc!
(the iPhone says 'Restore complete' as soon as I pulled out the cable. But phone stays as NEW phone, none of my backup data was restored).
During the 'restore from backup' attempts (via iTunes 10.7 on laptop), I have tried:
- Restoring to factory settings first and then restore from backup = tried many times and still failed.
- Uninstalled Apple mobile device and iTunes and re-installed them = still failed.
- Switched OFF the phone and hold the Home button while connecting to the laptop. Restored to factory settings, then tried to restore from backup = still failed!!
- switching to different USB ports on my laptop including USB 2.0 and USB 3.0 = no luck, still failed.
NOTES:
-Laptop is on Windows 7 and have had NO such problems so far. I have been using iPhone since 3GS.
-Internet connection is via wireless router, steady connection.
-My 3GS was on jailbreak mode before. I bought iPhone 4S and successfully restored from my '3GS backup' without any problem.
-iTunes 10.7 installed/updated.

Nevermind.. I just found the solution to my problem.
I copied the Backup folder into my mate's laptop and did the 'Restore from backup'.
All is good now.. Only need to re-install my apps, soon after all will be back as per normal!

I've lost internet connection after a power outage; how do I restore?

Check with your internet provider for help. Your modem or router could have been damaged if they did not come on after the outage. If your modem and router look OK all you should have to do is restart your iMac.

Resolve specific iTunes update and restore errors - Support - Apple
Configure your security software
Related errors: 2, 4, 6, 9, 1000, 1611, 9006, 9807, 9844. Sometimes as a result of this issue, a device might stop responding during the restore process.
Check your security software and settings, which can block ports and prevent connection to Apple servers during update and restore.

Lost internet connection when macbook wakes up

I didn't have any problem with this before until recently. The day before yesterday, when I woke up in the morning and I found out that I have lost the internet connection. I've always set my macbook to sleep after it idles for 1 hour (with that in mind, I never sign off AIM/ICHAT) but never (ever!) lost internet connection. Since then, this always happen everyday.
What happened here? Can somebody help me? Perhaps you could give e a step-by-step trick to make my macbook setting back to normal
Thank you so much

Map Loader Bug Re. Lost Internet Connection

Don't really know how to alert the programmers behind the Map Loader software to a fairly major software bug.
If the internet connection is - even very briefly - interrupted for even a second, the Map Loader software gives an error message.
BUT - big problem - the map selection CLEARS so you can't resume from where you left. Nor can you see which maps had successfully downloaded while the connection was active, so you have to download the WHOLE list again.
Please update for the next release.

D-Park,
Welcome to the HP Forum.
If you were using MAC filtering on your router, you would know how to fix this. If you do not know what it is, you do have have MAC filtering enabled on the router -- or you are not the router administrator. So -- don't worry about MAC filtering or go find the router administrator and ask to be let in (you will need the MAC address of the printer -- get a print out of the network page from the printer).
===========================================================================
Loss of network connection
Ordinarily I would suggest you reinstall the Full Feature Software for the printer because the installation can resolve a variety of ills associated with a disconnected wireless printer.
Install Full Feature Software - Printer
You did say the printer lost Internet connection -- this is a bit different from losing connection from your home network. You seem to be implying that your printer has lost its ePrint connection without actually saying you have lost ePrint.
The following document can help with both a disconnected wireless printer that is not cooperating -- even after you have tried reinstalling the Full Feature Software, for example -- and the document has a link to the ePrint Help and Tips documents that might help you if the issue is just one of ePrint and an Internet connection having to do with the printer and its connection to that service.
Wireless Printing Center
Take a look around at the sections -- you might start at the Troubleshooting steps and see what jumps out at you -- you might find your "issue" is right there and you can find the steps to fix it right away.

Lost internet connection..."A connection time out occurred"

I've read a number of recent threads blaming Lion for lost wireless internet connections. I wish my problem was that simple.
I have an AT&T furnished Siemens SpeedStream 4100 modem connected via ethernet cable to a Netgear 3500 router providing a wireless network. This configuration worked without problem for over six months serving an iBook G4 (OS X 10.4) replaced by an iMac (OS X 10.7) in mid August, Lenovo Thinkpad (Windows 7), iPhone 3GS, and occasionally a MacBook (OS X 10.5) and a MacBook Pro (OS X 10.6). Then last week my iMac lost internet connectivity and displayed a dialog box saying:
"Could not join NETWORK NAME. A connection timeout occurred."
At the same time, my iPhone lost its WiFi connection to my network, and could not reconnect; and the Thinkpad could no longer find my wireless network.
Thinking the problem was with the Netgear router, I substituted my 6 year old Apple Airport Express in the same configuration, but with a different wireless network name. (I had used this network setup successfully for over five years before replacing the Airport Express with the Netgear router in February.) The Airport Express network worked on both computers and my iPhone for a couple of days before I again lost internet connectivity exactly as I had with the Netgear router.
I called AT&T, thinking the Siemens modem must be at fault, since a problem with that one device seemed more likely than successive failures of two different routers within a few days of each other, or a simultaneous problem with a Mac, PC and iPhone. AT&T said their modem checked out problem free. I have now connected my iMac directly to the Siemens modem with an ethernet cable and have a problem free wired internet connection.
I need my wireless network. Any thoughts on what happened to my WiFi?

AppleSince86 ... we have this same problem with a wired version of 802.1x
It appears if a user updates their password (perhaps their login screen prompts this to do this)... the underlying eapolclient will still use the old outdated password to reauthenticate upon the next x min refresh interval.
This will basically kick the user off line.
Two things could really improve this process:
1) When the operating system reauthenticates for network access... use the absolute most current version of a users password
2) Timeout handling seems much more wonky in 10.7 / 10.8 ... could probably shorten all of the timeouts up a great deal... no need to wait 30 seconds error out... in reality... if you haven't heard back in 5 seconds, you're not going to.
Unfortunately, I haven't found any configuration files to control this from our end... it appears to be the compiled behavior of the apple code
