Loosing internet conncection

I keep loosing my connection to the internet. I am using a DSL modem and I think the problem is probably with the ISP (as the dsl light periodically starts blinking when connection is lost). When the light stops blinking, I simply have to re-connect and away I go. Sometimes the light isn't blinking and the mac shows a connection but there is none (in which case, I disconnect the internet connection in the menu bar and then re-connect and away I go). I was wondering if I could set up my Intel Imac to simply reconnect periodically.

I got the same problem!
My Imac core 2 duo - 2,4Gz looses connection to the internet from time to time for about 2 weeks now (everything worked fine before), ( Time-capsule with airport extreme). Can´t do anything about it...after a few minutes it works again for a while.
I have even recognized 2 freezes when beeing in sleep-modus.
Seems to be connected with one of the last security updates...

Loosing internet connection and wireless

I Intermittently loose internet connection using a wired port and the wireless icons will drop from both of my computer and PS3.
Some times internet and wireless will come back after a few seconds and other times I have to reset router. I play a lot of games online on both game systems, I usally loose connection once a night. Fiance says she looses connection on her laptop 0-3 times during the day.
Equipment:
-WRT54G v8 (just updated firmware)
-Sony laptop w/ built in wireless
-Desktop w/ linksys wirles card (dont know model #)
-PS3 running wireless
-Xbox 360 hard wired

Reflash the firmware and reset the router for 3 mins in a row.
hope that helps

RE1000 keeps loosing internet connection

I recently bought the RE1000 extender to improve our network at home.
I'm using the Linksys WRT610N router and Linksys WUSB600N adapters to connect, no encryption or mac filter.
My problem is that the RE1000 extender keeps loosing internet connection, the computers are still connected to the extender with full signal strength but no internet (Network magic icon with red X).
If I disconnect/connect to the wireless network when this happens the computer will connect to the router with only one bar strength.
To fix the problem I must restart the extender, then it works for a couple of days again before internet is lost again.

As you mentioned in your post that if you connect the computer with the router's network it connects with one bar but does it go online? If yes then connect the RE1000 from the Router and check the DHCP client table it will show the RE1000 IP address and then configure the RE1000 again… Here is the link for the configuration of the RE1000…
http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&login=1&vw=1&app=search&articleid=3760&userrole=Linksy...
Wireless settings in RE1000 will be same as router… In order to get the best performance from an RE1000 you need to place the extender in an area where you still have at least 50% signal strength to your router when you place it in the final location where the RE1000 will be used. Once after the configuration of the RE1000 try to connect the wireless laptop and check the connectivity…
Secondly in the DHCP client table the client name shows up with the Device name and not the Wireless Network Name…

Runninig 10.6.8 on new iMac. The last wo weeks I keep loosing internet and have to turn airport off and on to restore service. It is not the router as my two laptops do not have this problem. I read that in 2008 MMP's had a similar issue.Any thoughts?

Runninig 10.6.8 on new iMac. The last two weeks I keep loosing internet and have to turn airport off and on to restore service. This happens every time it goes into sleep mode. It is not the router as my two laptops do not have this problem. I read that in 2008 MMP's had a similar issues .Any thoughts?

Go to /Library/Preferences/System Configuration
Move all the files from the System Configuration folder to the Trash.
Restart your Mac. See if that made a difference.

Loosing internet when in DHCP and NAT mode

Hello and thank you for your help. I am a novice.
I am using a 2009 macbook pro 10.7.5 with Mountain Lion
Originally my airport extreme setup was for " DHCP and NAT ".
Since yesterday, I am only able to get internet via Bridge mode, but I have to sign in to my server network first, like a hotspot
This means that my internet timing is limited and the finder shows other personal computers that does not belong to my personal network. My iphone cannot connect to my personal network without signing in the internet service provider website first as well
What happens when I try to update and restart AE to DHCP and NAT, is that I loose internet and get the following message in the airport extreme icon :
"DOUBLE NAT:
This airport base station has a private IP address on its Ethernet WAN port.
It is connected to a device or network that is using NAT to provide IP addresses.
Change your Airport base station from using DHCO and NAT to bridge mode."
Now, I do not want bridge mode
My attempt to solve the problem was resetting AE to factory. This created a new network. The new network appears in the network icon and it is WPA2 personal protected, like the previous one.
I appreciate your time and look foreward to solve my problem with some help in here - thank you again

Originally my airport extreme setup was for " DHCP and NAT ".
If it was, and you had a modem/router or gateway type of device "upstream" on the network, then you created a Double NAT error on the network.
Sometimes, you can get away with this on a simple network, and AirPort Utility does provide the option to "ignore" the error on the network, so the AirPort Extreme will display a green status light.....instead of blinking amber, which signals that something is amiss.
"DOUBLE NAT:
This airport base station has a private IP address on its Ethernet WAN port.
It is connected to a device or network that is using NAT to provide IP addresses.
Change your Airport base station from using DHCO and NAT to bridge mode."
If you want to run in DHCP and NAT mode, you will have a Double NAT error on the network. Click the option to "ignore" the error.
Then, power cycle the entire network. That means powering everything off, waiting a minute, then starting the modem first and let it run a minute or two, then start the next device the same way. Keep starting devices one at a time about a minute apart until the entire network is back up.

EA6500 Loosing internet connection

Hi there
Last try before I send this piece of junk back to the dealer, and NEVER recommend Linksys again...
I have what appears to be a EA6500 model 1, it often looses internet connection. Sometimes there will be days in between, sometimes not. I usually cycle the power and leave it be for 10 minutes, and then it works againg. Also sometimes I need to reapply the latest patch - which is very old by now...
Any ideas, or should I just give up? I have tried most things now, except writing here, so you guys are my last resort!
Jacob

Hi pkk888. Have you checked your internet connection directly to your modem? If yes, what IP address are your getting behind the modem?

Why am I repeatedly loosing internet connection minutes after connecting to a wireless network?

Macbook pro retina display repeatedly loosing internet connection while it's connected to a wifi network. It always regains access after turning wifi off and back on, or by selecting another wireless network.
Already attempted:
Using another browser
Turning firewall off

Just reseted the SMC http://support.apple.com/kb/ht3964, it seems to have worked.

IMac Keeps Wi-Fi but looses Internet

Can anyone help with this as it's driving me crazy. my new iMac keeps loosing it's Internet connection even though it remains connected to the Modem Router and reports great signal strength with the Wi-Fi signal.
A Bit of Background Info
3 days ago I bought a new 27" iMac this is the 3.1GHz Quad-Core Intel Core i5 model and currently has 4GB of RAM which I'll be updating to 16GB in a couple fo days. This machine came pre-installed with Lion.
I bought this to replace my older iMac a 2006 model which is running Snow Leopard. I also have a MBP which is around 6 months old (I bought it just before Lion was released) and this also has Snow Leopard on it. On top of this I have an iPhone 4 and my wife has an iPhone 3G.
All of these computers and phones connect to my Wi-Fi network which uses a Belkin N300 Wireless Modem Router. This router itself is only about 3 weeks old and replaced a much older Netgear one that just failed one day.
When I was setting up the new iMac I used Migration Assistant to move accounts, documents, settings, everything from the old Snow Leopard iMac to the new Lion iMac.There were a few problems at first in doing this which may or may not be the cause of the problem I'm now experiencing. I'm going from memory here so I'm not 100% sure of the precise details but I'm pretty sure it went something like this:
1. Turned on new iMac for the first time and was prompted to add it to my Wireless Network which I did.
2. Connected a CAT5 cable between both Macs
3. Ran Migration Assistant but it failed to detect the old iMac
4. Disconnected the CAT5 cable and tried again, still failed to detect the old iMac
5. Reconnected the CAT5 but ran Migration Assitant first on the old iMac before running it on the new one. The new iMac then found the old one and the transfer began.
6. After an hour or so noticed that the transfer time was HUGE, like around 22hrs and realised that it must be trying to send it over Wi-Fi and not CAT5.
7. Aborted the migration but then both iMacs completely crashed and had to be rebooted by holding down the power button.
8. Rebooted new iMac but chose not to set-up Wi-Fi first and re-ran migration assistant with CAT5 cable attached. Transfer then worked taking around 3hrs.
9. On completion got a report saying that two programs hadn't been copied because they weren't compatible with Lion but both of these were programs I had previously uninstalled on the old iMac and this message was just referring to left over folders that hadn't been deleted.
10. Added the new iMac to my Wi-Fi network.
The Problem
The Modem Router is in the same room as the iMac (and all the other computers and phones for that matter) and is around 3 meters away from it with just a TV in between them and as such the Wi-Fi signal strength is always very strong on the new iMac (and all devices). However several times a day the new iMac just stops being able to access the Internet yet it remains connected to the Wi-Fi network. This happens whether I'm using the Internet on the new iMac at that time like surfing the web or downloading files or if I've just left the iMac on but am not using it. The cure is always the same and that is to right click on the Wi-Fi signal icon at the top of the screen, select Turn Off Wi-Fi and then turn it back on again. The length of time that I have working Interent on the new iMac can be a few minutes or a few hours it just seems pretty random.
When I do loose the Internet on the new iMac all the other computers and phones can still access the Internet and if I can still log into the router ON the new iMac and the routers status shows that it is still connected to the Internet. So the new iMac is connected to the router via Wi-Fi, the router is connected to the Internet but for some reason the new iMac just isn't getting the Internet anymore but if I turn Wi-Fi off and back on again on the new iMac it starts working again!
Things I've Tried
All the following are things I've tried without success.
1. Reboot the new iMac
2. Reboot the router
3. Turned of Wi-Fi on the new iMac, deleted my network from it's preferred network list, deleted all Airport passwords from my Keychain
I did notice the first time I did this that I had two Airport passwords listed under both Login and System (possibly caused when I first added the new iMac to the network before the successful migration?) but I deleted all of them and when I connected the iMac back to the network I now have one listed under Login and one under System
4. Added a new Network Location
5. Turned off Firewall on the router
6. Turned off Firewall on the iMac
7. I tried to use a Manual IP address but could not get this to work at all. If I used "DHCP with manual IP address” in Network > Advanced > TCP/IP settings and entered the same IP address that was automatically assigned to the iMac, 192.168.2.7, then it wouldn't even connect to the router at all. Setting it back to auto would make things work again but obviously still resulting in the dropped Internet connection.
Have I got a dud iMac, is there something I've missed, something else I can try?

Loosing internet connection

i have a mac os x 10.4.7 and i am using the apple internet. the airport is turned on and my question is why do i constantly loose connection and if there is anything i can do to fix this problem. thanks <3 kerri

Welcome to discussion Kerri, now I may not be able to help here, but if you could give a bit more information as to how you aactually connect to the internet, ISP, Airport Base Station? Airport Express, Ethernet, hopefully armed with more information our more learned friends here may be able to help you. Regards Jed

Loosing internet connection every 15 minutes

I am "loosing" my internet connection every 15 minutes. The cable box was replaced. Internet sharing is off. The firewall is on and no ports are checked. But, every 15 minutes, I get a message (using Safari) that there is no connection. I select network diagnostics and after I go through a few steps, all the buttons are green and then the connection works. This is very problematic, though, since I am loosing work while working online. Any suggestions?

Hi otobinchicago,
The fact is you can delete the .plist (com.apple.networkConfig.plist) and re-enter your setting and you will find out if this is the problem, but as I can assure you I have been through the same process. Reconfiguring the computer, the modem, etc, and it was the hardware.
You could try taking your computer to a friends house linking it to their modem and testing it that way. As long as the post-computer to ISP link is nothing to do with your hardware, you will see that it could be hardware or software.
My bet is that it is hardware. It sounds too similar to what I had.

Loosing internet when using 11n

Hello
I own a MacBook Pro (Late 2008), and just bought a Airport Extreme. I found in Network utility that I always connected to the b/g network and never to the n. I then manually changed the AP Extreme to divide it into two separate channels (airport and airport 5 GHz).
If I then swap to the 5 GHz, I always loose my internet connectibility and have large difficulties connecting to the basestation.
The network assistant has the connection as Active, speed 300, and I got an IP-address.
Can the problem be that I bought the basestation in USA and my computer in Sweden?
Grateful for all answers
Daniel Westin, VDM

Can the problem be that I bought the basestation in USA and my computer in Sweden?
Possibly, because although both countries use a number of common channels, each has access to a number of them that are unique for each country. In addition, the AirPorts do not necessarily have a complete set of channels available in any specific country it was designed to be used in.
The following is the list of available 5 GHz channels in Sweden: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, & 140
The US AirPort has the following 5 GHz channels available: 36, 40, 44, 48, 149, 153, 157 & 163.
As you can see, using the US AirPort in Sweden only gives you four channels (36, 40, 44, & 48) to work with.
To use this AirPort, you should change the Radio Channel selection from Automatic to one of the four listed above.

PLz help! loosing internet connection reapeatedly, I have a msi GT683 DXR

Hi everyone!

Doesnt matter if Im close to the router or far from it. have problems when trying to skype for example. Have never been able to make a skype call without connection problems. I get connection problems and get disconnected alot. Have 4 different computers both laptops and desktops/stationary working just fine. I have only had it for about two months, and havent installed much more than what comes with it. Drivers are updated using the MSI live update 5.
Even have the problem when connecting the network cable directly. Have a Net gear CG3100 router. Using encryption WPA2 AES. Anybody has any ideas? Or do you think its a warranty issue?
Many thanks!!

try downloading the driver from Intel i had the same issue and that corrected it

Keep loosing internet connection

I apologise if this isn't the right place ask this, but it I don't know where else to ask. We have a pretty regular problem with our internet. Most days (and sometimes a few time a day) we loose our internet connection completely and the only way to get it back is to unplug our router (a D-Link G604T wireless router) and then after at least 30 seconds plug it back in again. I've spoken to D-Link and they have said that the problem is with our internet provider (TalkTalk). I've also spoken to TalkTalk and they say they haven't got any problems and that it could be the router which they don't support, but it could also be the weather or that other people in the area are using the at the same time.
I just wondered what other people thought and it anybody else had experienced similar problems.
Thanks

do you have time machine set up?
if yes, observe to see if the internet drop out occurs EXACTLY when the time machine is backing up... if so, you've got the same problem as me.
solve issue, by turning off time machine or moving to ethernet.
here's a thread that helps

Loosing internet connection after Mountain Lion update

Hi,
I'm working with a MBP 2012 model.
After the update to Mountain Lion, the MBP is loosing the internet connection now and then.
I've did a PRAM reset, but the issue is still present.
Are there any tips oder way to solve the issue?
Thank so far

I'm having the same problem on my brand new 2012 Macbook Pro with Mountain Loin. After being online for a while, Safari or Chrome will just stop connecting to the interent, even though everything says it's connected. I don't have this problem with other computers on the same network that are not upgraded to Mountain Lion yet.
If I restart the computer, it works again for a while.
Very frustrating.

2014 mac mini loosing internet connection

Hi, my relatively new mac mini with most current system suddenly started to loose it's internet connection. WiFi or wired makes no difference. It works for a bit then I get time outs, spinning balls and nothing works anymore. All other devices on the same wifi (iphone, ipad, macbook pro, chrom book, windows laptop, apple TV) work just fine, so it's not comcast or a modem issue.
I'm mostly connected with wifi, I moved wifi up in the priority list. I also deleted that particular wifi account and entered everything again, it's a comcast router with wifi built in. Nothing helps. If I run the network diagnostics all things come back with a green light, but even if I try to ping some site via terminal nothing happens. All other devices run great, but I need this compuer on the net. I might take it to the genius bar, but I can't bring my wifi with me, not sure how much that would help.
Any other ideas?
It started sporadically, just a hickup in a video file or a minute to refresh a page, I had comcast test everything too. Now - regardless of what browser I use) I mostly get nothing, if I'm lucky I get a connection for a couple minutes before it's over again. Wifi is connected, I did not change anything or install anything (though some things might have done so automatically) and I know nothing about networking, so I never touched any of those settings, since everything worked anyway.
Any help is greatly appreciated, I can't work without internet on that machine :-(
Thanks!
