Internet Connection Issues between Airport & Cable Modem

I'm posting this because I couldn't find a similar answered question here, and I hope to save someone else the grief I went through trying to get my wireless network working.
Bought an Airport Extreme to connect to my non-wifi cable modem. The Airport had no difficulty setting up the network, and all of our computers and wireless devices were able to connect to the network. Unfortunately, none of them could connect to the internet.
The problem turned out to be that you need to edit the default network configuration to add the DNS server addresses of your cable provider. As soon as I did that, all the devices had internet. As far as I can tell, the settings live on the modem, but are not picked up by the Airport in quick setup process.
I hope this saves someone else a trip to the Apple store or a long support call.

Bypass the router and connect your computer directly to the modem.
Make sure that you can access the Internet when you connect the computer directly to the modem.
If you can access the Internet through the modem then try to configure the router manually.
Connect the modem to the Internet port and computer to Ethernet port on the router. Press and hold the reset button on the router for 30 seconds. Release the reset button and wait for 30 seconds. Now try to reconfigure the router manually.

E2000 keeps losing internet connection on Motorola SBV5121 Cable Modem

I bought a E2000 last week. Used my wired PC to setup which failed as it said internet connection not detected.
tried reinstalling after powercycling the modem and routers but still it could not detect the internet.
I used my friends macbook pro to setup router wirelessless and the E2000 + internet connected successfully.
I connected my PC using ethernet and it worked bingo! Shortlived as in 2 days again no internet was detected. Now i have tried everything but no avail. My friend out of town so cannot try reinstalling it using Mac book.
Any known issues with the cable modem and Linksys E2000?
Thanks

Macbook crashes when internet connection is lost from cable modem

for the last couple of weeks Comcast internet has been failing at almost the same time every day - around 10am. i have spoken with them and they know they have a major problem in the area. the issue i have is that my MacBook Pro, when the internet goes down, completely crashes shutting itself down & restarting with that multi-language message that my 'computer has had a problem.' i have run every diagnostic, Disk Utility Repair, deleted applications, used Wifi, used ethernet, on and on and on...
most of the time, i cannot even restart the MacBook. if i disconnect ethernet or turn off WiFi - no problem. it goes through the startup flawlessly.
one other strange thing happening is i have two websites that will never completely load. no problem on the iPad or iPhone 6, only the MacBook. but these websites don't have to be open when the crash happens.
any ideas? i am running Yosemite 10.10.1. oh, and it happens when i am running Safari, Chrome or Foxfire, though it seems to happen a lot more since the last Safari update. thanks...

OK, for sake of argument:
1. Quit Safari
2. Check the ownership and permissions of Home -> Library -> Safari folder and write those down (click once on the folder and select Get Info from the File menu, and make sure the triangle is dropped down on Ownership and Permissions so all the privileges are shown).
3. Drag Home -> Library -> Safari to the desktop
4. Reopen Safari
See if the issue reproduces itself. If the issue doesn't reproduce itself, then it is something corrupt in the Safari info for your user. If it does reproduce itself, something is wrong with your user level internet settings or possibly Corefoundation settings which Safari is sensitive to.
You can always quit Safari and move back that folder to where it came from and make sure the permissions are retained.

My airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

my airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Airport Extreme Base Station Internet Connection issue

I have a connection question for Airport Extreme Base Station.
I have Comcast cable broadband. I connect that to a Linksys router for
use with my Vonage phone, and then from the Linksys router I connect
via Ethernet to my iMac. I like the direct Ethernet connection for
performance reasons.
In order to set up a home network to connect my Tivo's (and eventually
my PC and printer), I have set up an Airport Extreme Base station and
connected it to the Linksys router from it's ethernet connection to the
WAN (cable modem) input on the Extreme.
I have connected to the Airport network with my iMac, but since I am
connected to the Internet via Ethernet, I cannot tell if my Airport is
connected to the Internet so that I can use it for my Tivo. My PC is
still in storage from a move, so I can't check with that.
My question: How can I tell if my Airport is connected to the Internet
without disabling my Ethernet connection on my iMac?
A few more info points/questions in case it helps answer:
1) I previously used this Airport to connect this iMac wirelessly.
2) Should I be connecting it to the LAN port since it's coming out of
the router?
3) If the connection issue is because I am going through the Linksys
first, can I connect the modem to the airport and then use the LAN port
to connect to the Linksys router?
4) If I have to disable the ethernet connection to test the Airport,
how do I do it? Just unplug it?
I appreciate any help as the online and manual help from Apple is not
quite up to par with such a complex configuration.
Regards
Bill

2) Should I be connecting it to the LAN port since it's coming out of
the router?
No, connecting to the WAN port is fine.
3) If the connection issue is because I am going through the Linksys
first, can I connect the modem to the airport and then use the LAN port
to connect to the Linksys router?
The issue is that you have two routers which effectively creates two networks. Unless this was your original intent, you will want to setup the AEBS as a bridge.
To set up the AirPort Extreme Base Station (AEBS) as a bridge, using the AirPort Admin Utility, connect your computer directly (using an Ethernet cable) to the LAN port of the AEBS, and then, make these settings:
Network tab
- Distribute IP addresses (unchecked)
- Apply the new settings.
- Wait at least 5 minutes.
4) If I have to disable the ethernet connection to test the Airport,
how do I do it? Just unplug it?
Well, that's certainly one way, but an easier way is to temporarily disable the "Built-in Ethernet" in your network configuration.

EA6900 Internet Connection Issue - Desktop connected via ethernet cable

Hi there,
I have an HP p6837c, 64-bit OS with Windows 7 Home Premium. It is directly connected to the EA6900 via ethernet cable. My internet connection constantly drops (as in variably every 5 seconds to 5 minutes) then re-establishes itself. I have no internet connection issues when directly connected to the modem. All of the wirelss devices that are connected via the EA6900 are working without any issue. My husband's laptop, which has Windows 8.1, functions with no problem when directly connected to the EA6900 via ethernet cable. We've tried swapping out the cable. We've tried adjusting the MTUs per Support's suggestion. Nothing has solved the issue
Any thoughts on what the issues might be? Settings? The version of Windows? Any help would be much appreciated!

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router and PC, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
Router and Wired Configurations
Setup DHCP reserved IP addresses for all devices ON the router. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Ensure devices are set to auto obtain an IP address.
If http://en.wikipedia.org/wiki/Ipv6 is an option on the router, select Local Connection Only.
PC 3rd Party Security Software Configurations
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router.

What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router. Its a VoIPo device. The cable modem is connected to the VoIP WAN port and the LAN port on the device feeds the Airport Extreme. The VOIP is working fine, and my Mac are getting 10. addresses from the Airport Extreme. But I do get confict messages and lose my connection periodicaly. Looking for help.

Its a VoIPo device.
Per chance, is this device the Grandstream HT502?

Internet connectivity issues on Mac

I was wondering if there was any solution to an internet connectivity issue I'm having on a mac. It seemed to start when I purchased a new modem: an iPrimus AudioCodes MP252 wireless router. Basically the internet connection will either drop out or become stagnant/very slow. There have been no connection/speed issues on any Windows PC or laptop, but often when you try to use the internet on the mac it precipitates a network dropout, thus affecting the connection on Windows computers as well.
I'm trying to see if there's anything else that can be done besides taking it in to be serviced. ISP support hasn't been able to fix the issue, so perhaps it is some sort of compatibility issue between that particular modem and Apple Macs. Obviously the last resort is buying a new modem.
Modem: AudioCodes MP252 Series wireless router
Mac: Mac OS X Version 10.6.8

If that doesn't work try changing channels on your Router.

Random, frequent connection drops between Airport Extreme and MBP

I've had my Airport Extreme (on 7.6.1) and MacBook Pro (on 10.5.8) for a bit over a year.
Never experienced any connection issues.
4 days ago, connectivity issues started out of nowhere (no updates etc). MBP would sometimes not find the Airport at all in Airport Utility (and then of course also can't find the network), and the connection will just break up intermittently - sometimes every 5 minutes, sometimes every half an hour.
Interestingly, other devices work flawlessly, particularly Xbox and PS3, without connection issues. My DSL modem is just fine, so the issue must be somewhere between the MBP and the Airport Extreme.
WHAT DID HELP (so far)
- Turning WPA/WPA2 security off entirely, but I cannot have my WPA off forever as neighbours will use my connection and we don't have flatrates in Australia
WHAT DID NOT HELP (so far)
- Switching from WPA/WPA2 to just WPA
- Changing the radio mode
- Switching Connection Sharing from "Share a Public IP Address" to "Off (Bridge Mode)"

I have tried a billion more things since, but the one that seems to have at least improved the situation is to downgrade Airport Extreme to 7.5.1 and change the channel from #1 to #7

Multiple Internet Connection Issues

Hi there, long time reader first time poster.
I figured I should post this as, while having read through hundreds of similar posts I still can't figure out how to solve my connectivity issues.
I just bought a new iMac 21.5 inch 3.2Ghz i3 model and while I am happy with the machine overall, it is the second one in a month - the first had a faulty ethernet port and refused to connect to the internet out of the box. Apple replaced it without question - almost as if they knew.
The replacement has now seemingly developed the same issue.
Some background info. The computer was connected both through ethernet and through the TC I bought to back it up until yesterday. So I was getting both a wireless signal from the TC and one through ethernet.
I have a hub that has 5 devices connected to it ( Printer, Cable TV, iMac and TC - now a PS3 ) That hub is served a signal by a simple NTT modem connected to a phone line. That modem is now nearly 5 years old but has always given great net speeds so I don't believe the problem to be the modem - I could be wrong though.
I just bought a PS3 and tried connecting it yesterday but had multiple problems. Despite me entering the correct PPPoE information to the letter, the PS3 refused to connect, saying the password and username was incorrect. I could connect it via a Bluetooth signal but no hard wired connection would work.
So I unplugged everything from the hub, shut down all the machines, turned off the modem and let it sit for 10 minutes and then plugged the ethernet cable from the PS3 straight into the modem, giving it a direct line. Switched on modem, rebooted PS3 and tried again - this time it connected through ethernet. I still don't know how or why. I can guess but I'm sure you guys know much more about this than I do.
So then I tried connecting the iMac back to the net, reconnected all the hub, followed the same procedure. Off, sit for a bit, on etc. This time the PS3 has no connection and now the iMac has no connection either!
The TC gave a green light though so I was able to get wireless. I tried removing all net locations from the iMac, installing new ones, renewed the DHCP lease, but no matter what I did (PPPoE info 100% correct) it just refused to establish a connection.
The the bloody TC light flashed amber and I couldn't get wireless either despite being plugged into the hub and getting a signal! The PS3 is now working and the cable is fine so I am starting to think either I have cluster ****** the whole setup or something is wrong with the iMac.
I go away for an hour then come back and the stupid TC has somehow picked up a connection! The light is green again?! But now the time connected display is scrolling repeatedly. I've got net but what the **** is wrong with all this?
Bottom line - not ethernet connection for the iMac but TC seems to be working and all other devices have a connection.
Please help me if you can! I just can't figure any of this out.

Your description is a bit confusing, but I use English as a second language, so it may be just me.
1. How is the hub connecting to your modem, by ethernet cable or wirelessly?
2. Which device is negotiating the internet connection with your ISP, the modem?
3. Does the device that negotiates the connection use PPPoE?
4. How are the other devices being handed their internet connection? DHCP only?
Only one device should be connecting directly to your ISP using the PPPoE protocol and configured with your account username and password. This device is preferably the modem. This device should be configured to hand out internal IP addresses to the other devices on your LAN using DHCP. All of the other devices should be configured to request an IP from that device, whether by ethernet or wi-fi, just with DHCP.

TS1317 Internet Connectivity Issue - specifically with the DNS settings

Hi there,
I'm wondering if someone can help me resolve an internet connectivity issue on my MacBook Pro.
It appears to be a problem specifically with the DNS settings. I am connected to the internet but can only reach a website by typing in the IP address, not the domain name. The error messahe says: "Unable to resolve server's DNS address."
Regardless of whether I use Wifi, 3G modem or cable, i get the same error.
Operating System is Mac OSX Version 10.6.7
Please help!
Thanks

It sounds like your MacBook Pro has either incorrect or missing DNS IP address information in it network profile. Let's start with your wireless connection. You would find these in System Preferences > Network > Wi-Fi > Advanced > DNS tab
If your main Internet router is performing as the DHCP server, it would provide the DNS IP addresses (typically from your ISP) on this tab. You may have two or more addresses listed. If they are grayed, that means that the addresses are coming from the DHCP server.
In the following example screen shot, I am using DNS servers provided by OpenDNS. Notice that they are grayed as they are being provided by my main Internet router. Again, these should be either ones provided by your ISP or ones you purposely set up, like my OpenDNS ones.

Ethernet connection only after reseting cable modem

Hello,
Can anyone help me? Today at work, I plugged an ethernet cable into my my mac air and got a connected green light, but no internet access. The same happened when I took my laptop home. Here, I just reset my cablem modem, and it worked. I would feel very awkward reseting the cable modem at work because everyone shares it and that would put everyone's work on hold. What can I do tomorrow at work to make the ethernet connection access the internet without reseting the work cable modem?
Thanks so much for your time,
Kavaitri

Internet Connection lost between AEBS and Mac through LAN

For the last year I have had no problems with my AEBS. I have it configured like this: My Modem is connected via ethernet cable to my AEBS and then out to my G3. I have no airport card in my G3. All of a sudden I get no outgoing signal from my AEBS to my laptops, nor can my G3 get an internet connection unless I plug the modem directly into the G3 and bypass the AEBS. I am frustrated beyond words and my teenagers are impossible to bear without their wireless connections. Ideas? Thanks

Welcome to Apple Discussions!
Do you have a cable or DSL connection? If you have a DSL connection, you may need to reset your PPOE settings.

My brand new mac pro always had Internet connection issues at school. WHY is that? I see the school's Internet working perfectly fine on other PC's, but there is never a day where my mac doesn't have Internet connection issues at school. How do I fix it?

I got my mac pro in the middle of August. School started the week after. Internet was working perfectly fine at home. But at school, I never had a good connection. Sometimes on the good days I get a connection when I'm sitting at the exact spot in class I always sit at. It's ridiculous and it's frustrating. I invested my money into this laptop and I'm beginning to regret it. I thought it was the school's Internet, but I don't see Internet issues with other PC users. It's most frustrating on registration days and I'm trying to register for my classes before it gets taken, but again... Internet connection issues. It's random. Majority of the time, it doesn't work at all. I've done Network Diagnosis and turning WiFi off then turning it on again. I've done everything I could. I put my money on this laptop and it was a lot of money. I could have bought an 800 dollars laptop and I would have Internet connection anywhere on campus. So, I don't want to continue everyday to regret on buying this laptop every time I try to connect to the Internet at school or Starbucks or anywhere else. How do I fix this? What's the problem ?
At school, I heard this guy had a problem with Internet connections too and he owned a new mac book pro. He said something like Apple messed up on something, but he fixed it. If I knew mac book pro's had these issues I wouldn't have bought it in the first place. It's freezing on me every other day. It's ridiculous. But what concerns me the most is the Internet connection. So someone please tell me what can I do next to prevent the problem? Am I doing something wrong maybe?

Hi Kevin,
I'm using an XLR input mic which is connected to the phantom power enabled XLR mic socket on a USB M-Audio M-Track. The M-Track is connected by USB to the Mac Pro - so effectively I've got an M-Audio USB soundcard with a mic input. I've also tried a microphone that is a straight XLR to USB cable (guessing with some soundcard chip buried in the usb plug) but that also yields the same effect of bad latency, intermittent quality, stuttering and repeating and echoing (without the speakers on during record so its not feedback).
The mic works absolutely fine with other recording applications I have on the mac at the moment - albeit non-adobe ones (tested it on the EasyAudioRecorder - and it lives up to its name. it's easy)
I will try with Audition and report back, but sitting here right now I can imagine it would work fine with audition too - it just seems to be the way premiere is set up for recording into the timeline is a bit sketchy. I'm willing to accept it might well be a quirk with the new Mac Pro trashcan - I'm not weighting all the woes on premiere.
Any thoughts or am I out of luck to sit with my fingers crossed for a fix in the next round of updates?
Nathan.
