Keep losing internet connection

The solution that worked for me was to turn off ALL my wireless devices, (game consoles, PC's, laptops, mobile phones, ipads, wireless routers, Apple TV. I even powered off my cable modem. I then powered them back up starting with cable modem, wireless router (airport), macbook pro and then the remainder of the devices. I have been told that the culprit was my APPLE TV device. Some people have simply recycled the APPLE TV device and resolved the issue. In any case, I have not had the problem since and it's been a few weeks... I'm not suggesting this is the "silver bullet", but it is one more thing to try...

Bubba, I've stated this somewhere else in the forum but I tried literally everything then broke down and called Apple support. This individuall knew exactly what to do and led me throught the steps (sorry, I've forgotten) but it involved clickind certain preference on or off, etc. It took about 3 mintues and I have never had the problem again. I'd try and hope you get someone as knowledgable as the person who fixed my problem. Good Luck

This is pretty much what has been happening to my iMac lately. It will randomly drop connections every 30 seconds or so, and the only way to get it back online is to either stop and restart the wifi, and / or switch locations in network settings if it's hard wired.

Very frustrating .. it only started doing it after we set my airport to act as a bridge with my new Century Link C200)T router, it never did it with my old 600 series modem from CL. And, it is primarily just this one computer.

I've tried editing my airport settings and changing the channel and haven't had this issue since. It seems the problem was that I was somehow getting interferance from the other networks near me (the last years 20 new have shown up!). So try this and it might fix it.

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!

The wireless on the imac27" works intermittently,actually very little. With an ethernet connection it works fine.

Called Apple care and they went through their gyrations, but never got it to work. Took it to an Apple store, and the

wireless connection kicked in immediately. Took it to a friends house, and it kicked in immediately as well. We have an xbox, a roku box, HP laptops, macPro laptops, and ipads. Everything works on wireless except the imac.

The apple care expert told me that I had a problem with Comcast my internet suppler, which is hardly the problem, since their responsible to supply the modem connection, and it appears that if there is a problem, it's with the router. I can't imagine the router causing the problem, since everything else works just fine. I wish the apple people would address this problem, and not make you feel that you're at fault. No doubt that the solution lies with them.

Incredibly frustrating...this issue started a few days ago and continues to get worse...every 10 seconds my MacBook drops Internet connection. Unbelievable that Apple hasn't addressed these concerns yet.

So...I rebooted our Comcast router, even though NO other computer, iPad, iPhone or otherwise dropped Internet connection, but it seemed to help keep my MacBook connected. Hmmm, that tells me there must be something with the MacBook...not my MacBook only however, as the others posting on this thread are not using MY MacBook. I'm grateful I can stay connected, but will be looking to see how Apple addresses this issue which appears to be Apple related.

I have a Roadrunner Surfboard modem with 2 Airport Extremes and a Time Capsule connected via ethernet and all set on bridge mode with multiple devices wirelessly connected to each AE and the TC. I lose internet connectivity on my MB Pro on the TC (although on Airport I can still see all the AExtremes and the TC) multiple times each hour. The problem appears to be the TC and not the MBPro since I lose phone wifi internet and iPad internet through the TC at the same time). WHen I lose internet, the other devices on the Airport Extremes are working fine. The Airport Extremes and the TC are set up exactly the same way, so it appears to me that the fault is in the TC. This is a relatively new problem for me (recently upgraded to modem with multiple ethernet connections) and it is annoying as ****.

Upon further review, non MBP devices (iPhone and iPad) are still connected and working when the 'internet goes down for the laptop. The laptop has not gone down when on the Airport Extremes.

So it appears to be the combination of the Time Capsule and the MacBookPro.

Hi all, firstly sorry I didnt read all posts as there are quite few, maybe someone else posted something similar. I just noticed internet going out (literally every few minutes) and "fixed" by turn off wifi and turning on again, buying myself a few minutes.

I just bought my Mbp a few weeks ago (a mac newbie), using it daily without problems....

UNTIL I went ahead and allowed keychain to save a password on a website login.

I believe this was the culprit as I have literally made no changes to macbook other than keychain password save. My fix (so far so good 30 minutes later) was to open keychain (finder, click applications and search "keychain"), on top left click "local items" and I deleted all. My mbp is still new so not much to delete, plus I still remember my passwords. ;-)

This worked for me and possibly for you.

I'm not "making the connection" of how the Keychain password save solved your problem (by deleting local items).

Is it still working for you?

The problem I am having is only with my iMac. (late 2009)

My iPod Touch, iPad 2 and Macbook all connect without incident to my wireless network, but the iMac keeps dropping.

I think it's definitely Mavericks causing the problem, for me, anyway.

Hi, I had read somewhere that there was something wrong with keychain and it could cause the problem.

IT DID NOT. It seemed to help (initially)but the problem persisted. I contacted Apple again and in the end they suggested a reinstall of Mavericks (hold command and r when starting up). I did a full reinstall and deleted everything (nothing to delete really as I did not migrate to new mbp yet). STILL HAD PROBLEM! Interestingly only had problem with apple apps (chrome seemed to work just fine)! ITunes wouldn't connect and safari was sporadic connection. Contacted apple again and they asked if I had installed java since doing full reinstall, I had not yet. So I installed java and it seems to be working. Very strange problem. :-/

Thanks for letting me know that the Keychain didn't work.

Interesting about Java. Which version of Java did you install?

I just spotlight searched JAVA and nothing comes up. Where did you download from? Could you include a link?

Thanks🙂

I just googled "java download" and went from there. Sorry am on holiday and didn't bring with. I assume it was latest version. Hope it helps.
