MBA Loses connectivity

I have a 2011 MBA which has connectivity issues. At first I thought it was a known problem with the wifi that I saw on the net quite extensively. But Im beginning to think my problem is different. The reason is that I have the same ISP at home, office, parents, inlaws and best friends house. The problem only occurs at home.
The problem is not with the wifi really. I never lose connection between my MBA & the wifi router. The problem is that the internet connectivity is temporarily lost for stretches of 1-3 minutes at a time. Then i have to either change the DNS or renew my IP from the router or refresh the page or a combination of all of them for a simple page like Facebook.com or Yahoo.com to continue loading. The page begins loading and stops, keeps loading and stops, continues and stops intermittently.
My ISP is sending a tech next week to look at the problem but they almost never know what to do. What parameters on the wifi/router can I have him test to see if it fixes the issue?

Ok I have access to my ISP wifi/router. I can change whatever I want. What do you guys suggest I change?
My MBA is 2011.
I have the same ISP at home, office, in laws and parents house and friends house.
I connect wifi in every location without issues. Navigation is fine.
Only at home I have the issue. I'm permanently connected to the wifi network.
The issue is that I lose Internet connectivity on and off. Pages start to load and stall. All of a sudden they load again and so it repeats.
My iPhone and iPad navigate fine.

MacBook Air loses connection to internet but not LAN

Hi, I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here http://www.tp-link.com/en/article/?faqid=417), which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem).
I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection.
My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes:
1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets
2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).
3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.
4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets.
The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.
Any suggestions for what I can do to stop this problem?
Thanks
John

No. If connected to WiFI served by Technicolor, the problem does not occur (even if the other AP is connected to the network).

Unfortunately, Technicolor in router mode is required by my ISP.

Yes.

Yes. A Windows machine and several iOS mobile devices work flawlesly for me.

No. The problem occurs only if connected through additional AP.

Not yet. I will not have a chance to do it for the next few days though :/

Macbook Air loses connectivity every time it sleeps.

For about a month now my Macbook Air loses connectivity to wifi whenever it goes to sleep. I have it connected to my personal wifi and when I leave the MBA idle it goes to sleep after 15 mins. When I wake the computer it is still connected to my wifi, but the connectivity is gone. I have to turn airport off and then turn it back on. It regains connectivity immediately after that every time. However, it obviously shouldn't do that and it is annoying because it interrupts my downloads. I have tried playing around with the settings and reading the discussion boards. While people have had similar issues, none have been exactly the same and none of the troubleshooting has worked. Wanted to see if anyone had any suggestions or fixes for this. Thanks in advance!

Hello BrettG81,
I know that can be frustrating when your MacBook Air does not maintain a Wi-Fi connection. There are a few things that you can try to get it working again. I know you have done some looking at your settings and possibly some adjustments, but go over the first article as some of the troubleshooting for OS X Snow Leopard and Lion can be helpful. Another troubleshooting option is to create a new network location and test it out to see if you still have the same issue. All the steps are linked below.

Client Macs lose connection to server after Sleep

Ok, so my previous issues with disk I/O erroros with contacts/Mail etc appears to be resolved after I re-installed ML Server and ML clients on all my macs -- not entirely sure why but now I have new problem where client macs lose connection to the server after sleep
So my current setup is as follows:
Server Mac
Mac Mini Server running ML 10.8.2 Server
Client Macs
2 x MBAs with 10.8.2 (Core2Duo & iCore5)
1 x Mac Mini running 10.8.2 (Core2Due, 4GB 2.4 Ghz etc)
Issue:
If I leave the client Mini logged in say, as me and either the mini goes to sleep (or if I put it to sleep) and then I wake the mini up, I appear to lose connection to the server - so whilst I am still logged in as me, I've lost my connection to my home directory e.g. Doc/Music/Pics (I can see instantly my desktop picture defaults to ML galaxy picture, opposed to something I've chosen) folders are no longer present. So obviously as mailbox,iphoto & itunes libraries are missing, Mail, iPhoto & iTunes fail to operate and I my only course of action is to log out and log back in and everything is fine.
I get the same issue - although not as frequent - on MBA's when you close it and results in having to log out and in again to resolve the issue. I also saw the same problem when it was running Lion as well.
A couple of things to note:
- Server Mini is never asleep and is running 24x7 (as its a media streamer as well)
- Its only occured when in deep sleep - so if I wake the mac up after a few seconds of sleep, its just fine but if say I leave it overnight and wake it in the morning, its no longer connected.
Any pointers will be welcome and given that it appear to have occured on a client Mac with Lion as well, it would imply its an issue with the server rather the individual client Macs. Also note, I don;t recall the problem when running Lion Server.
Thanks
Rob

Have you tried looking at the server logs, particularly the 'System' & 'Open Directory' log sets?
Anything seen in there?
Also logs on the client machines using the Console app. It's a bit tedious going though logs but they can be very illuminating.

Windows 7 Pro Client loses connectivity to internal Win2k8 web server

1. affected workstation are Optiplex 380 running Win 7 pro sp1 with broadcom NICs.
2. Internal users use a internal webserver for customer invoicing application. Users lose connectivity to this internal web server, all other networking works, network shares, internet, etc. If I try to ping the webserver IP I get no reply. XP
machines are not affected. Not a DHCP issue as there are plenty of IPs.
3. I have tried different internal NICs (3com) but still had issue. I have upgraded BIOS, nic drivers. etc.
4. I rebuilt one of the machines using Windows XP pro sp3 and have had no issue with that workstation.
the problem started a few months or so ago. I have not been able to determine the source. I tried running wireshark but nothing stuck out. I have changed the session settings on the IIS server from 15 minutes to 6 hours but did not make a difference.
5. Today when client lost connectivity to the server I tried pinging from the server back to the client and the connection was restored. This issue really has me confused as I cannot find anything in the logs that sticks out.

Hello,
Thank you for your question.
I am trying to involve someone familiar with this topic to further look at this issue. There might be some time delay. Appreciate your patience.
Thank you for your understanding and support.

Remote app on iPad connects to iTunes but then loses connection.

Hi,
Basically, I can get the app on my iPad to connect to iTunes, but if I then start doing something else on my iPad, or my computer goes to sleep, then the remote won't connect again. Even if I wake my macbook and try to connect it again.
If I press 'add an iTunes library' in the remote app, nothing appears on iTunes.
To solve the problem, I have to restart my computer.
I just checked to see if my iPhone connects and it worked straight away. Maybe its a problem with my iPad?
Can anyone suggest anything?
Oscar

I too have this problem and made it worse. Under Mavericks and iOS7 everything set up very easily and worked beautifully like Apple stuff usually does. Then a couple of weeks ago I took the dive and updated to Yosemite, iTunes 12 and iOS8 and then I would occasionally lose connection with my iTunes library as described by the second poster. Very aggravating. So I made a bigger mistake and deleted the library from my iPad Remote app and whenever I started it up again it would say 'Add a device'. I clicked and a randomly generated 4 digit number appears with the exact instructions: 'To add an iTunes library, open iTunes on your computer and choose Remote from the tab bar'. I went to iTunes and searched EVERYWHERE for this Remote tab bar and could not find it. I then went to iTunes Preferences: Devices and clicked the button 'Forget All Remotes' thinking this may reset something in iTunes and make the Remote tab appear somehow to start from scratch. Wrong! Now there is absolutely no connection between the Remote app on my devices and iTunes on my computer.
Can anyone point me to this Remote tab in iTunes?? If I can find that then I think I should be able to fix this.
Geez, talk about effing up what should be (and was) a very simple app.

HP Officejet 4620 All-in-One Loses Connection to Wireless Network When It Goes Into Sleep Mode

My HP 4620 All-In-One wireless printer works fine until it goes into sleep mode. Once it goes into sleep mode, it doesn't wake up if a print job is sent to it. If I wake it up manually by pressing the blinking on/off button, it still doesn't print. If I completely turn it off and then on again, the print job that was queued on my computer will start printing, but that's a huge pain and waste of time nearly every time I want to print. I've installed all available updates. I also assigned a static IP address in an effort to correct this but nothing helps. I see that others have complained about this problem, but I do not see that anyone has had success resolving this. My operating system is Windows Vista. I use a Link-Sys Wireless G Router. Thanks.
This question was solved.
View Solution.

so I have called HP tech support 12 times over the last 6 weeks and still my HP Officejet 4620 loses connection overnight. Of course becasue it was a birthday present I spent more time than I normally would have on this issue. While the tech are very polite they have not fixed my problem and now it is too late to return printer to store. This is a lot of money wasted and I think they need to admit this is a bug in this printer and resolve the problem!!!!!

Officejet Pro l7580 Constantly loses connection to wireless laptop!!

Hi and thanks for helping.
I have an Offiecejet Pro L7580 and use it on my network, servicing a desktop and a laptop. The desktop is wired to the router while the laptop is wireless. Concerning my desktop, the printer connection is solid. It is 100% dependable. My laptop is a completely different story. I noticed that it would connect just fine and print, scan, etc... But after about 10-15 minutes it tells me that it is disconnected. This has been a continuous problem. Both systems use win.7 Ultimate 64 bit.
I found out that if I go into my D-Link DI-524 wireless router and change my wireless channel from one to another, it automatically reconnects. This means that my printer... or laptop is losing a connection due to channel activity. I have tried multiple channels in case of wireless interference from other devices. It happens all the same. This either sounds like a printer firmware problem that loses connection when the router channel cycles, or my laptops network card (even though I never lose connection to the internet). My laptop uses a buffalo mini usb wifi adapter (thanks to a widely known problem of DV series factory defects).
Please help me find out what the problem is.
Thanks,
Jason

Here are a few things to try:
1. Update the firmware on your router.
2. Set a static IP address for your printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). Yours is 192.168.0.100 to .199 Enter 192.168.0 220 for the IP address.
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Leave the gateway and DNS blank. Click 'Apply'
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

IPad3 loses connection to home network and same happens to laptops.

I purchased the new IPad a week ago. Since then, I often lose connection to home network. Cannot join network unless I power off and on the modem/router. This also hapens every morning. The same is now happening with our wireless laptops. Never had any problems all these years until the iPad was introduced to our network. Our Internet provider confirmed that modem/router protocols were set per advice from Apple Support and they did additional tweaking but problem persists. I am thinking of getting a new modem and router but wonder if it is worth it. Has anyone had similar problems where their other devices are having the same connection issues as the iPad? Thanks.

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

Apple remote app loses connection

I am using the remote app to control my Itune on my computer on Vista. I am able to initiate the connection. But when I close the remote and re-open I still see the library but I am not able to open it.
I able to reconnect if disable and re-enable home sharing.
*I have no firewall activated
*WiFi conection working perfectly
*Same problem from my Ipad and my Ipod.
I did all recommend troubleshooting from apple with no success. I read a lot of post on web about that problem but it seems that it should had been fix in the latest version.
Any idea
Thanks.

I have the same / similar problem.
Just after starting iTunes (10.1.2) I can see the library in remote (2.1), can connect and control iTunes.
This works fine for a couple of minutes, then the remote app loses connection to iTunes. The library turns from black to grey in settings, can nor be found nor added.
I have tried this on two different Vista PCs and three different routers with all firewalls turn off.
Looks like a straight forward bug to me. Any ideas please?

MacBook Pro loses connectivity to netgear router every few weeks. All other wifi devices in my home work (iPad, iPhone, tv,). If I go near the router, I can reconnect, but maybe only for a few hours. So every few weeks I reinstall Netgear software. NG.

Every few weeks I lose connectivity to my Netgear N router. Its becoming more frequent. All other devices in my home work fine (ipad, PC's, iphone, etc..). In order to work for a few more weeks, I reinstall the Netgear software (using Ethernet cable to router) . This is a hassle. I use WPA-2. Every once in a while I can reconnect without reinstalling the software if I go NEAR the router. But this connection doesn't last too long (a few hours).
What do I do?

My wifi loses connection to my phone and laptop at the same time every 30 mins or so.

Hey all.
I have a WRT160 V2 router with firmware v2.0.02. I have had the router for years without any problems. A few months ago I have started to see an issue where I lose connection to my internet on my laptop, and wifi on my phone at the same time. I have wifi calling on my phone and it disconnects also at the same time. All of a sudden, everything will stop working, then about 40 seconds later, it all works again. I lost the connection maybe every 30 to 60 mins
Does anyone have an idea what can be causing this issue? Thank you.
It is really annoying because I rely on wifi calling for my primary phone, and I end up getting cut off when talking to people. BTW wifi calling is for all tmobile phones, but also normal wifi to surf the web on my laptop and phone drops too at the same time.

I would suggest that you isolate the problem. You may start the isolation by connecting a computer directly to the router (hard wired connection). Observe the connection for couple of hours. If the connection is stable, problem might be on the wireless settings of the rotuer. If the connection is not stable, do further isolation. Connect the computer directly to your modem. Observe the connection for couple of hours. If the connection is not stable, call your internet service provider. If the connection is stable, problem might be on the router itself. Upgrade the firmware first (firmware available in the website: Ver.2.0.03 Build 9). After the upgrade, reset and reconfigure your router.

SSAS loses connection to local workspace

I seem to be running into this quite regularly these days. I'm editing an SSAS tabular model, filtering data in the views in VS 2012 to verify that calculations are working, and I get this:
The result is that any work you've done since you last saved is lost, because you won't be able to save. It's really getting quite frustrating.
I did find a post online that went over how you could recover your work from your local workspace SSAS install by reverse engineering/scripting the cube out of it, but that's really not an option in my case since I'm using source control and can't dump my
project history every time this happens (and it happens multiple times a day now).
Does anyone know of a workaround for this issue before I open a support incident? Thanks.
Edit: Seems that screenshots don't get persisted to the messages in MSDN forums anymore. Here's the text of what would have been in the screenshot:
"cannot complete the operation because there is no connection to the workspace database that contains the model currently being edited"
Specific steps to re-create. Filter any column in the tabular designer, and when you go to clear the filter if you hit clear before the list of available values populates in the box below, it'll lose connection to the workspace server, and everything will
be lost. Any attempt to save will result in:
"Unable to save the file Model.bim. Reason: The file cannot be saved because it is marked as readonly"
Some posted elsewhere about getting past this issue by un-setting the Model.bim file as read-only, or unsetting the entire project directory and it's contents as read-only, but that has not worked on any workstation I have ran into this problem with.
I suspect this is only one of several ways to cause the issue - I know about this one, I try and avoid it, and I still run into problems occasionally.

Hi K Dahl,
According to your decsription, you can't save the bim file and it throw the above error. Right?
In Analysis Services Tabular mode, this error occurs if the tabular designer has lost the connection to the workspace database server at some point during the editing session. However, there is a way to recover the work you did since the last save of the
model. Please refer to a blog below:
Recovering your model when you can’t save the BIM file
If you have any question, please feel free to ask.
Best Regards,
Simon Hou

Airport express loses connection and blinks amber until restarted many times a day.

I have an AirPort Extreme as my,main router with a gen 1 airport express and 2 gen 2 express as range extenders to cover all 3 floors and outdoor area. I have an Insteon HUB connected to one 2nd generation express and an Insteon IP camera that is on the far edge of the WiFi coverage area. About 3-5 times daily, the express will blink amber and lose connection. I need to either restart the network from airport utility or just unplug and restart the specific express. This fixes the problem but only temporarily. Why does this occur? Is it due to the wireless camera losing connection? It seems to occur when I try to access the camera or devices thru the Insteon App. I have purchased the additional express thinking it was a poor connection to the other range extender but this has made no difference. I have been on tech support with Insteon for many hours,and they are unable to help. Any suggestions?

Hello Daniel Epps. Welcome to the Apple Discussions!
Every few minutes, it seems to temporarily lose its connection to the internet and start flashing amber until it reconnects. It's extremely annoying. Does anyone know why this is happening? Is it an airport problem, or a cable modem problem?
It could be either or neither ...
It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing you from getting a good clean signal, and what I would check for first.
I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:
o MacStumbler, or
o iStumbler
