Internet connection loss...

Hi there... I'll try and explain this as best as I can, I don't think this is exactly a Mac problem but we don't seem to have the issue with the PC's in the house.
Basically, for one reason or another I seem to get 'interruptions' of some sort in my internet connection which seem to cause very brief losses in my internet connection resulting in my computer thinking that there is no internet, even though as soon as you go back to something it's working again.
For example, I'll be downloading something and the downloads will suddenly display 'no internet connection' and as soon as you hit resume it's fine again. Or in YouTube the video will stop playing halfway through even though the red line has reached the end (if that makes sense), it's as if it got a signal saying 'you've got the whole video now' even when it hasn't.
This makes life difficult for lots of reasons, but the main one being that certain updates or large files I can't download because they don't let you 'resume' from the amount it's already downloaded. Subsequently I have to start again and you can guarantee that it won't get up to the 130mb (or whatever) before it seems to lose the connection again.
I hope this makes sense! I've just lived with it ever since I moved here but I'm getting continually fed up with it. I do live in a small village at the very end of a phone line and I do get very slow broadband as a result (they told me that on the phone), but how I check for what's going on here I don't know.
The strange thing is 2 PC's in the house don't seem to suffer from the same problem. You can always download anything on them and no interruptions (at least I think that's true, I don't actually use them much but I did recently download a 450mb file that the Mac just wouldn't do).
I will happily provide more info if it's useful, I'm just trying to get the general idea across here. If anyone knows where to point me or what I should do I'd be very grateful.
Cheers! Sidx

Hi, I've only just read the 'Intermittent WIFI' thread here, and wonder if this is the problem I'm experiencing? I do get what is being described in that thread (and will add to it later), but I experience drop outs even when airport doesn't visibly start scanning, i.e. the dropouts happen when I appear to have full connectivity to my router. I only get the 'airport scanning' issue every now and then, maybe once a week, maybe less. But then I'm nearly always plugged in if that makes a difference..?

Internet connection loss using Airport Extreme and Netgear DG843

Hello,
I am accessing internet via a Netgear DG834 router (not wifi), connected to an Airport Extreme base station. Most of the time, I can access internet through the Wifi network of the AEB without any problem. But around once a day I am experiencing connection loss and the only way I found to restore it is to reset the Netgear Router by physically unplungging it.
Both the Netgear and the AEB have up to date firmware, so I suspect some kind of problem in my setup, as I am not an expert in setting up networks.
Is it possible that using a Netgear Router connected to the AE (which is also a router if I understand correctly) could cause connection problems ?
I am at a loss, and do not even know how to describe the relevant informations of my current setup. If a kind soul could help me nonetheless, I would be very gratefull.

Is it possible that using a Netgear Router connected
to the AE (which is also a router if I understand
correctly) could cause connection problems ?
Yes.
Ensure that that the AEBS is configured to not distribute IP addresses.
Also ensure that the AEBS is on a different channel to the DG834G.

Airport + WDS: Internet connection losses

Good morning all!
I have a WDS network with
- one Airport Express (Called "A") used to ditribute an Internet connection. This is the WDS main station.
- one Airport Express (Called "B") that extends the initial network AND that streams audio with Airtunes. It is a WDS remote station.
When I surf the net (via "A") during a song is streamed on "b", I loose my IP address, the audio stream is down, the Internet connection too, and I must ask a new IP address (via the "repair" button) to restart a new stream on "B".
Each time I click on a link the same problem repeats!
Could somebody tell me how I could solve this problem please?
Thank you so much and best regards,
Geoffrey

I am going under the pretense you have seen this set-up diagram.
http://docs.info.apple.com/article.html?artnum=107454
Be sure to take special care to read this set-up thoroughly. As another point of interest sometimes Interference can cause a loss of or interuption in the signal. Sometimes a simple relocation of the main can do the trick, while at other times it may require you to find and eliminate this issue such as.

Hi
Having said internet is not routing via MPLS, Even i think to be a DNS issues,
Try to check the below
Ensure all the client DNS is set to AD DNS server
In AD DNS server ensure its not forwarding DNS query to Other site
During outage check any client PC manually changing the DNS IP to 4.2.2.2
- all client DNS are set to AD DNS server
- I checked the properties for the AD DNS and found there are 3 forwarders listed.
The first IP is at Site A which is resolved.
The second IP I am not sure about since it is not even in our subnet (not resolved)
The 3rd IP seemed to be for an old DC that is no longer operational (not resolved).
- During outage if I change client machine DNS to 8.8.8.8 or 4.2.2.2 they can access the internet.
I guess my issue is with the forwarders. Would the right step be remove all 3 forwarded and add 8.8.8.8 and 4.2.2.2?
Thanks.

Internet Connection loss after losing connection between 2 sites

Hello,
I have started working for a company over a year ago and recently we are running into an issue with losing internet after a loss of connection between companies site. Below is a summary of setup.
Company has 2 locations, Site A and Site B..both same domain
Site A has DC and other servers such as ERP, Document Control Software.
Site B has DC, Printer Server, File Server and other essentials servers.
Each site has own independed 20 MB connection.
Site A and B are linked via MPLS and only used for ERP, Document Control software, and DC traffic.
Recently we started to have frequent connection issues with the MPLS and as a result I started to notice none of the users at Site B can access the internet such as google.com, msn.com...etc. As soon as MPLS connection is restored interent works.
The DC at Site B was setup before I started working for company.
I have been trying for the past few days to figure out why Site B is losing connection when MPLS Tunnel is not operational...but so far no luck.
I am very sure that internet traffic is not routed via MPLS because when internet is working the IP lookup such as "whatismyipaddress.com" points to ISP IP address for site B. Also when doing tracert to external website the route is via ISP for
Site B.
I think this issue is related to DNS but cannot tell the cause or how to fix?
Thanks for assistance in advance.

Internet Connection Loss Repeatedly

So for past two days my modem(the internet light) keeps turning off every 20-50 mins. I've turned the whole thing off and tried reseting it and still this problem persists. I came on the forum looking for similar problems, and I'm wondering if this rain has caused an outage near York, PA which is causing my connection to drop so often. I;ve had this problem in the past and it eventually got to point where it dropped every other 3 mins.

Johnvolt, is it only the Internet light going out? Or the DSL light as well? As suggested posting some tranceiver stats would help a lot.
@Bk_Bridge Both your dowload and upload speeds aren't running at full bit rate. You are also on a range extender card for the DSL. A loop length (length from the Central Office to you) would also tell you a lot about your service. Based on the attenuation numbers though you seem to be close enough the office to support your service. Also creating your own post will help draw attention to the issue you are experiencing.
@Josieedvl Tranceiver stats would be a great start to your problem. Also as suggested above creating your own thread would help generate responses.

Time Capsule crashing daily: internet connection loss

I recently bought a 1 TB Time Capsule and started using it as the primary router in the house. My wife and I have laptops (2006 MacBook Pro Core 2 Duo, MacBook Pro Unibody, Windows laptop) that use the connection.
What would happen is that my laptop (2006 MacBook Pro) and my Windows laptop would lose connection to the internet, but my wife's (Unibody MacBook Pro) would stay connected for awhile before losing the connection.
The Time Capsule, when it would get into this state, would show a green light. I can connect to the Time Capsule's wireless network ok, but I wouldn't be able to connect to the internet. When I try using the AirPort Utility, it can detect the Time Capsule, but it wouldn't be able to fetch the settings (the progress circle would spin endlessly).
If I unplug and plug the power cord back in, it works again, but I've had to do this once/twice a day. I shouldn't have to do this, though - does anyone have this problem? Any solutions?
I'm on the latest firmware (7.4.1).

Same problem here. Had to restart (tearing out the powercord...) the time capsule and my Airport Express everyday.
Just went back to 7.3.2. Apple has released major ******** with 7.4.1...

Internet connection loss when not in use

Hi, earlier this week I picked up a Mac Mini G4 running Mac OS X 10.4.11. I have it plugged into the interwebs through it's Ethernet port. The cable runs straight into a DSL modem. The modem seems to be working fine. All lights are on as they're supposed to be. When the internet is in use, the computer browses the web just fine. When left alone for a bit, the computer loses it's connection to the internet. The connection is also lost when the computer is in use but the internet is not being used (tying in Word, fiddling with Garageband for a long time etc). In the system preferences, under network, the status of the Ethernet flashes between "Built in ethernet is currently active and has the IP address ..... You are connected to the internet via built-in-Ethernet." and "The cable for built in Ethernet is not connected." Halp!

I am having an identical problem. When I go to the network settings - choose built in Ethernet - then connect - it processes and connects using the PPPoE password settings. I can then surf on safari or firefox. If I log off either or put the computer to sleep, when I log back on all settings are lost and I have to go thru the whole process again. Vianet said not their problem. Belkin said not router problem as Internet lights are all active. But if I use the airport utility I get zero Internet. What can I do? Mac mini is from 2005. Also 10.4.11.

New FIOS customer with dropped VOIP calls and Internet connection

I am a new FIOS customer. Got my 50/25 connection a week ago, switching from a TWC 6/1 connection. Ever since the new connection, I've had numerous issues.
My VOIP (Ooma) connection constantly drops and re-connects during conversations
I've had random Internet connection losses, which picks up again after a few minutes
My home alarm starts chirping every once in a while
I've contacted Verizon several times due to these problems and have received varying answers with no resolution of the problem.
The first time I spoke with support, the tech logged into my router and changed the WiFi channel saying that would fix the problem. It didn’t.
The second time I contacted them, the tech ran a bunch of diagnostics and said everything looked fine so it must be an IP address conflict with my devices, because I had a couple devices using static IP addresses. He said everythinf should be DHCP and the last two digits could not be higher than 99 (192.168.1.99). He said FIOS does not support 3-digit numbers at the end.
So I changed all my devices to DHCP and ran some online VOIP tests. It showed a packet loss of 2-5% and MOS score of 1 (which is bad). I was still getting dropped connections, so I disconnected all devices and connected just one computer to the router and tested again. I was still getting packet loss.
Then I called support a third time, this time the tech said there were no 2-digit IP restrictions and that he was detecting there was no UPS baterry backup for the ONT which was probably causing the problem, so he dispatched a field tech to my house.
Today the field tech came (same guy as before), he took one look at the box and said it was too close to my Electric meter and the RF from the meter was causing interference to the FIOS connection and resulting in dropped connection.
He moved the ONT to another location and said that should fix it.
Well, I'm still seeing packet loss and low MOS score when I run the VOIP test.
I don't know how much of what the techs are saying is true and how much is made up stuff.
Has anyone had similar issues and have thoughts on solutions or likely causes for dropped VOIP calls and connections? Could RF be causing this?
I thought going from a 6/1 Cable connection to a 50/25 FIOS connection would be awesome, but this has turned out to be a nightmare, and I may have to switch back to cable if the problem is not resolved.
I would appreciate any help.
Thanks!

Don't know where the packet loss is happening. I ran the VOIP test on myspeed.visualware.com and it shows a packet loss of 2-5% at different times and a MOS score of 1.
The report says MOS should be around 4 for good VOIP calls.
The Verizon tech who came to the house just blamed the electric meter box for RF interference and move the ONT farther away.
My concern is that I'm getting different answers from different techs at Verizon.
Regarding IP addresses. The Router shows a DHCP range from 192.162.1.2 to 192.168.1.254 as available for devices on the network. So, if I need to assign a static IP to a device should I use a number below 99 or above 151?
Thanks!

Why does my macbook intermittently lose internet connection when I have internet service?

Hello,
I have checked around on Apple forums as well as the wider internet. My situation is just a bit different than the other solutions I read about.
I have a MacBook, 10.6.8. I have an internet antenna that plugs into the modem, that I plug into my computer. What I have not found in the forums are solutions to an internet connection loss that happens with a hardwired internet connection, ie ethernet wire, not wireless.
I contacted my isp and I was told there is a very strong connection. The internet will cut out when I open another window or just at random times, maybe for 20 seconds. This is very irritating.
Skype and itunes run just fine even when the internet cuts out. I feel there is a problem with one or my of settings. Any help is greatly appreciated.

Most often BitTorrent, iCloud or some other cloud-data application is involved in cases of mysterious bandwidth use by a Mac. If you use iCloud, uncheck at least Photo Stream and Documents & Data in its preference pane and see whether there's any change. If you use third-party network backup software, disable that. If you use a torrent client, remove it.
Otherwise, there's no easy way to monitor network usage per process using built-in tools. If you're an advanced user and you want to try, see the manual page for the nettop(1) shell command. It may or may not provide the information you're looking for.
The third-party products Rubbernet and Little Snitch are supposed to record network usage by processes. I can't vouch for them. Both were available as free trials, the last time I checked. I suggest you uninstall either one when the question has been answered.

TM Backup to TC, Internet Connectivity breaks during backup,

Prior to the Snow Leopard Time Machine would backup, wirelessly to my Time Capsule without issue.
Since Snow Leopard, many times when Time Machine is backing up, I lose Internet Connectivity. If I stop the TM backup, I immediately regain connectivity. I connect to the TC wirelessly and it is my ONLY access point. I have a different Internet Router, the TC is just a bridge.
I do not lose the Airport connection, the Time Machine backup will finish to success. It seems to mostly happen when TM starts after waking from sleep. If I manually start a TM backup, the problem does not occur. Again, this presented after upgrading to SL.
My Wife's MBP which is still on Leopard, backs up to the TC without issues (no internet connectivity loss).
I did not think to ping other devices on my network during the occurrence of this anomaly. Next time it happens... I will try to ping other devices to see if I have any visibility past the TC (access point). I will report back the results.
Any ideas would be greatly appreciated.

Internet Connectivity Issues, 511 CPU Fan not detected

Hello,
I have been experiencing some issues with my HP ENVY Pohenix 800-060 (running Windows 8.1) PC lately.
My internet connectivity has been acting crazy. Pages won't load fully. For example, when I am on Facebook I can't scroll down and have more posts load. I have to hit refresh and sometimes it will let me scroll down further than before. To load sites sometimes I have to hit refresh. If I am using just the wifi I am constantly connecting and disconnecting at totally random intervals but it's stable if I use an ethernet cable (however the other issues still persist). Images won't load fully as seen here
Also, starting yesterday when I restart my computer I get an error message that says 511 CPU fan not detected. I have opened my computer and dusted the fan and I have also unplugged it and plugged it back in to the motherboard to make sure it's securely connected. What's strange is that this only happens about 8 out of 10 times when I start my computer, and if it does happen I can simply touch the fan to get it started and it will work just fine until I turn my computer off.
I noticed in the HP Support Assistant that if you update to Windows 8.1 it says that you may experience internet connectivity loss and hardware problems so I don't know if these problems are related or not. I have checked and my drivers are up to date according to the HP website that searches for updates for you.
I am currently backing up my computer and plan on resetting it to factory default if I can't find the source of these problems.

Eldrscrolls, welcome to the forum.
Please check the CPU fan thoroughly before using the computer futher. If it has failed you could fry the components. I don't know if it has liquid cooling, but if so, be extremely careful.
A System Recovery is a very good idea. After updating Win 8.0 to 8.1 on my HP Split, I had several problems, such as, wireless connectivity. I did the Recovery back to Win 8.0. It solved my problems. After a few days I gave Win 8.1 another chance. It has performed admirably. If the system is overheating because the CPU fan failed this could cause your problems, also.

Loss of internet connectivity after upgrading to windows 8.1

Hi, After upgrading to windows 8.1 from windows 8 i am experiencing major problems , loss of internet connectivity for no reason both I.E. and G/CHROME are now taking an age to open there are no virus issues as far as i can see.
I have uninstalled and re-installed windows 8.1 about four times over the past 9 months or so and the same thing happens after all the updates are in it runs like a dream for say 6weeks or so then i get the same faults as described above then i uninstall/ re-install ok for 6 weeks .
I would apprieate any help or advice thanks

Hi @BMATH
Thank you your query.
I understand that after updating to Windows 8.1 about every 6 weeks you loose wireless connectivity for no reason and the web pages are very slow to open. If you uninstall and reinstall Windows 8.1 it works fine again for about the same amount of time. You have done this about 4 times with the same result each time.
Do you know if there is any changes at that time , perhaps an update?
You stated you do not believe you have any viruses. Just to be sure here are two links that will help confirm that.
Microsoft Malicious Software Removal Tool
Microsoft Safety Scanner
After updating to Windows 8.1 have you checked for Windows updates?
Have you ran HP Support Assistant ?
Here is a link to Troubleshooting Wireless Network and Internet (Windows 8) that may also help.
If the issue should remain please contact HP support for assistance.

Sporadic Rotating Loss of Internet Connection for Just Some Devices

Hi,
We've been having a problem where one or two of our devices (phones, laptops, iPads, Apple TV) lose internet connection for 10-30 sec at a time, while the others are fine.
As best as I can tell it's a full loss of connection, not just something running very slowly due to us pushing the bandwidth limits. I've experienced the latter elsewhere and this manifests very differently. It will instantly and fully disconnect a person from an online game or drop a skype call without the accompanying prolonged lag or distortion of bottlenecked bandwidth.
It happens at all times of day, and does not seem related to our peak times of bandwidth usage, nor the general public's peak times of usage.
We should have enough bandwidh for our usage, and usually we do. Our system is 25/25 Mbps and during our peak use at most we would probably have 1 laptop gaming, 1 HD video stream, and 2 non-HD streams. However, like I said before, the problem seems unrelated to overall bandwidth usage. The same problem occurs even at midnight when our local usage is minimal.
Overall we have 6 laptops, 5 phones, an iPad, 2 microcell signal boosters, and Apple TV, in total connected to the FiOS. We have a property with tenants where the signal is distributed via 3 WiFi routers and one direct ethernet cable to my laptop, and one to the Apple TV.
It happens on devices that are both connected through the WiFi (wife's laptop, phones, iPad) and ethernet (my laptop, Apple TV). It can happen with devices that are a few unobstructed feet from the WiFi router. However, it anecdotely seems to happen more on our phones than laptops.
My hunch is it is something outside our local network. This is because our equipment and usage has basically remained unchanged over the last couple months. (We got one new microcell tower for a different carrier, one new wifi router, but overall same # of people and patterns of usage.) And yet the problem seems to be getting worse. Back in probably early November I don't remember this problem occuring at all.
My second best guess is there are more devices connected to the network than it can handle simultaneously, and it rotates which gets kicked off. Maybe this was occuring before but we didnt realize it.
My third guess is it has to due with signal interference with the various WiFi routers and microcell boosters. However, this seems less likely since it also affects devices connected via ethernet cables.
Any thoughts or advice is much appreciated! Thanks!
-Ned

Ok, so in the mean time we decided to upgrade our service so I've only tried this solution now.
My problem though now is I can log into 192.168.1.1, then give my verizon admin password, and then set my channel preference. That seems fine for changing the main network input and wifi router (call it A).
However, we have another wifi router (call it B) which is fed from A via a cable. I cannot figure out how to change B's wifi channel. Therefore I worry if we have only switched A, since A feeds B (as well as the 2 microcells) they will all still be on the same channel and therefore still interfering with each other.
I have tried www.routerlogin.net (and .com) as written on my netgear router and I get "http://searchassist.verizon.com/" telling me "Sorry, We could not find www.routerlogin.net". I have also tried logging into wifi router B via all the 192.168.1.X addresses I see listed on the Verzion account when I log in via 192.168.1.1 (in total I tried all the 192.168.1.[1-24] options).
Thanks for the help!

Unexpected shutdowns and loss of internet connectivity on brand new 420t

Hi,
I was experiencing unexpected shutdowns (would see safe mode choices when turned PC back on) and also intermittent internet connectivity issues.
To Fix:
In device manager, I turned off the option in the Realtek Network Controller Power management tab to allow the computer to turn off this device to save power.
It's been working like a charm so far (2 days). I'm not so sure HP should be building PCs with this option set. There are no updates that I haven't installed either. PC still sleeps (can see nic lights go off) and wakes up just fine.
Other that that we really like this PC...Beats Audio wasn't impressive with only the internal speakers, then I tried a good set of external tweeters and a subwoofer and then it was realized.
Hope this helps someone.

Troy,
Thanks for the suggestion. It sounds like you've heard that others have had this problem. Is that right?
And are you suggesting that the kernel panics and the loss of Internet connection are related? They often happen independently of one another.
Claire
