Imac losing internet connection

Hi my imac keep losing its internet connection, it does this twice in a couple of hours and everytime I put the mac to sleep, I have been into the network settings and put my wifi to the top of the list, but this has not helped. I have Mac OS X version 10.7.5 2.8 GHz intel core i5 and 4GB if that helps. Thank you

I have been having having a similar problem for the last several months. When I turn on my Imac about 70% of the time it does not connect to the network. I have to click on the Airport icon on the menu bar and wait about 5 seconds before my network shows up. Then I can manually connect to the network. Very frustrating.
One thing that has helped others but not myself is changing the multicast rate to the lowest possible setting. (Utilities, Airport Utility, manual, wireless, wireless options).

My iMac keeps on losing internet connection. Webpages get stuck after a minute or so. If I check the internet connection via diagnostics it seems to work just fine. Others, like the iPad use the same wifi connection and never fail. What can I do?

Running 10.6.8 on Intel dual core iMac, it keeps on losing internet connection. Webpages get stuck after a minute or so. If I check the internet connection via diagnostics it seems to work just fine. Others, like the iPad use the same wifi connection and never fail. What can I do?

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Why is my macbook pro running so slow and losing internet connection?

Why is my Macbook Pro downloading so slowly and losing internet connection frequently?

Write off the MS stuff as indicators for now--starting with Office 2008, they developed very long launch times. The time to launch 2008 on my old 1.25Ghz G4 and my MBP 2.2G are virtually the same. Even document opens/saves are slow compared to Office 2004 and earlier.
1) You have adequate hard drive space so that eliminates one of the usual suspects.
2) Check for runaway background processes. Quit all running user applications so the computer is at normal idle. Find Activity Monitor in Applications > Utilities and launch it. If you've not run it before, change the "Show" pulldown at the top of the AM window from its default of "User Processes" to "All Processes." There is a column for "%CPU." Click that column header to sort by CPU usage. Watch the processes "bubble" for about a minute to get a better picture of the usage.
If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated. My MBP shows nothing using more that about 5 percent on any given test run as long as I close all my user apps.
3) If you have never done any sort of maintenance procedures, taht can slow you down. Simply restarting the computer a few times a week clear a lot of temporary files. You also may wish to review this article on the Mac OSX periodic maintenance scripts, which, if run, also do a lot of cleanup:
http://thexlab.com/faqs/maintscripts.html
There are other useful articles on file maintenance associated with the one. Here's the index:
http://thexlab.com/faqs/faqs.html
Check out articles with "Maintain" and "Tuning" in the titles.
4) Use Disk Utility to check the SMART Status of your hard drive. A failing drive can make things slow before it makes things stop.

Airport time capsule losing Internet connection?

My airport time capsule is losing Internet connection but I still have wifi? Any suggestions?

It could be your modem, or other problem on the ISP's end. Try resetting your modem - power it down and let it rest for a few minutes, then power it back up again.
If it is a cable modem, also disconnect its coaxial cable - literally unscrew it and leave it detached while the modem is powered down.
Leave the TC powered up during that time.
After a sufficient amount of time has elapsed reconnect the cable and power up the cable modem. If you're still having trouble contact your ISP.
The possibility of a TC problem exists but the sort of failure you describe is not common. If all else fails perform a "hard reset" followed by reconfiguring the TC. Your Time Machine backups will not be affected.

My MacBook Air which is only 3 months old, keeps on losing internet connection. To reconnect I have to click on the internet icon on the top bar and click turn wi-fi off. I then have to click turn wi-fi on and it reconnects after a few seconds.

My MacBook Air which is only just over 3 months old, keeps on losing internet connection.. To resolve it I have to click on the internet icon at the top of the page and then click turn wi-fi off. I then click turn wi-fi on and it reconnects. This resolves it for a while, and then it disconnects and I have to go through the same procedure again. My BT Home hub is fine because my wife's i pad and our phones are all ok. What can the problem be?

Can I share my iMac's internet connection with my Touch?

I have a DSL modem and do not have a wifi network setup. Using Lion, can I still share my iMac's internet connection with my Touch?
If so can you give me step by steps? Will this be something that I can turn off and on without interfering with my regular ethernet internet connection?
Thanks. Asking this for a friend who is scared that she will somehow mess up her existing internet connection if she tries to set this up. She
called AppleCare to get them to walk her through this and they denied any knowledge of the ability to do this. Huh?

OK. Remember this is just a form of texting, so it's not easy to discern whether a question is explicit or rhetorical. Sometimes you have to give the reader a clue.

WRT160N losing internet connection

Hello,
I have a router WRT160N and is randomly losing internet connection. I should reset at every 5-50 seconds but is unlikely to do this. I prefer to insert the internet in network card, instead reset it every minute.
I've reset the router, I've restore it to factory settings with no result.
Internet is OK, cable is OK, MTU is OK, routing table is OK. What isn't OK?

Click here and select the correct version of your router, download the firmware and upgrade it...It should help you get a stable connection...Change the MTU to 1400...

Do they have plans to fix the bugs with Yosemite. I keep losing internet connection on my Mac Book

Ever since i installed Yosemite on my Mac Book pro i keep losing internet connection. Should I go back to mavericks because I just hate this Yosemite or do they plan to fix the bugs soon? I did a complete clean install and I am still having problems. I see a lot of complicated solutions and I am not that tech savvy to go into my settings. Thanks

All software has bugs. The first release (which you have) will be the worst.
Many advocate not upgrading to a new operating system until it's been out for 3 months or longer. In the Windows world many recommend not upgrading until a full year has passed.
So yes, most / some bugs and glitches will get fixed over time. If you wish to reduce your difficulties in the future wait a while before installing ANY new OS.
I suggest you post specific details on your Internet problems. How are you connected etc.

This subject has been talked/written about a lot, after Lion was introduced. A solution from Apple has not yet been published, everybody is waiting.
Try for instance https://discussions.apple.com/thread/3734081?start=15&tstart=0, but there are more discussion groups with the same subject: frequently lost WiFi-connections in newer Macs running Lion or up.

***Time Capsule intermittently losing internet connection***

Hello, Here's the story:
My Time Capsule intermittently is losing internet connection. The light is green for 5-10 minutes at a time, then turns amber for 2 minutes and loses internet connection.
At first,..I thought it was the TC going bad. Went to my local Apple store and had it replaced under warranty.
Still,, the same situation was happening.
Then talked to AT&T (DSL) and they checked the connection. They deemed it was OK and possibly the modem going bad.
Went to Best Buy and purchased a new modem. Installed, put into Bridge Mode,...interenet working OK.
Still,...the same situation that it stays on for 5-10 minutes, then loses it for 2 minutes.
Any ideas? Could it still be the ISP (AT&T)?
Last thought,...my neighbor uses Uverse (AT&T) for his cable/ISP and he is expierincing cable/ISP outages ramdomly. I am using DSL (AT&T) too but through my phone line. Are the two possibly related?

You need to run the modem in router mode..
I would either bridge the TC or remove it completely because you need to get exact log info from the modem.
Do isolation test.. ie remove all phones and filters and other devices from your phone line. Reboot the modem.. and wait for restart to complete.
Copy out of the modem the full line stats, sync info and even better if you can get cli access and do some deeper level stuff.. (most of the tools I use are PC only.. ie dmt tools).
Then make sure the log is turned on and giving max info and watch your connection.. if it drops without anything happening on the modem,, then the ISP is having issues.. which is possible although connection of cable and adsl is loose or non-existent.
If it drops sync keep track of how often and the line stats, Particularly the SNR..
See if you have an rf noise source in the house.. more if you are interested.

I Fixed my iMac slow internet connection

I will share with you how I fixed my iMac slow internet connection and frequently lost connection. At first, I thought it was the Airport but then it wasn't the case. I also had a Dell laptop in the same basement and it was running as fast as I expected. Here are the steps:
1/ Open Airport link on the top right window > Open Network Preferences
2/
Click + to create new Network Name and Security, I chose WPA personal - less security than the WPA2- that is why it runs faster.
3/ Go mack to step 1 and select your new network name > Apply.
May iMac is now connecting to internet as fast as I would expected.
Good luck

My iMac internet connection is not faster but as fast as it used to be. I was using WPA2 and it was really good for a year and then I got disconnected or very slow. So I created the new network bearing the same old name but use WPA and did not delete the old one, some how everything is back to normal.

Losing internet connection every hour

Hi Guys
I replaced my Linksys router with an Airport Extreme 4th Gen about 2 weeks ago
I keep on losing Internet Connection when connected through a Wireless connection. This happens with my Windows 7 PC's, with my iPhone4 and with my iPad2. The connection with the AE is kept alive but the passthrough to the Internet does not work anymore. I have to reset my wireless adapter to reconnect and rebuild my internet connection.
Fyi,

I really hope someone can help me out here.
I do not want to go back to my good old Linksys...

I have a similar problem with a new TC 2TB unit. I have ATT ADSL service using a Speedstream modem. PPPoE is setup on the TC and it works and connects. All features of the TC are working (wi-fi, Back to My Mac, Time Machine, etc...) and the light is solid green on the TC.
Periodically, the LED blinks amber and I've lost Internet access. The Speedstream modem shows all green lights. I have found that power cycling the Speedstream modem brings the TC back to solid green after about 2 minutes.
I am seeing this happen about once a day and it can happen overnight when there is no network activity. I am thinking that the lease on the IP address given by ATT expires and the TC does not know enough to reinitiate a connection. I have set the PPPoE Connection to Always On and experienced the problem. I have also tried setting the Connection to Automatic and set the Disconnect if Idle setting to Never.

IMac keeps losing internet connection

Hi I have just bought an iMac. Unpacked, set up, and away I go.
Problem. Every 30 secs or so, the internet connection stops! Only on the iMac. I have an iPhone 4 and iPad 2 and they are both connected to the internet using the same WIFI in my house.
Is there a known problem here your help would be very appreciated.
Thanks.

Well... I found something that did work for me... and I have the wifi continously working for more than 48 h now.
(to be done as admin)
1. Turn Off wifi
2. Open terminal
3. Type "sudo open /Library/Keychains/System.Keychains"
4. Search and delete the network passwords
5. Close the window
6. Reboot the iMac
7. Turn on Wifi and put your passwords again for your network
Hope that helps for you too
Cheers
