Internet connection dies once DLINK 502 modem is attached to Airport, why?

I'm recently bought a DLINK 502T to get online. It's working - just - as long as the modem is plugged
into the Macbook via ethernet. But as soon as I plug the ethernet cable into the Airport Express the internet connection dies. I have reset, restarted, done the usual but to no joy. The airport connection is fine, the green light is on and according to the modem the ADSL connection is fine - so does anyone know where the fault could be? Used the airport recently on another set up and all was fine... Could this be a modem issue?

Figured it out, well, after a couple of hours googling anyhow.
Basically my DLINK modem/router was competing with the Airport Express - which is also a router, if not a modem.
So I needed to put the DLINK into 'Bridge' mode. So it dealt with the modem side of things and the Airport the routing side - and as soon as I set it to Bridge mode the airport did the rest. As ever a simple solution to an at times maddening problem. All is now wi-fi and sweeet - the 10.5.2 has done not time either apart from the 'airport scanning' GUI oddity.

My airport express frequently drops the internet connection. Once I unplug it and re-plug it in, everything is fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

My airport express frequently drops the internet connection. Once I unplug it, and re-plug it in, my Macbook Pro17,IMac 24, iPad air and my wife's Acer 15 works fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

It is tricky..
But yes it can be done as long as you use a different IP subnet to what is being used for the internet..
So I need to know what modem router you have?? Does it have wireless as that would make it very easy?
What IP is the computer getting?
Then I can give you the details to setup wireless statically on a different subnet.

Internet Connection Lost Once 2nd Router Added to Network

I am at a point of complete loss and frustration and absolutely cannot figure this out.
About 4 months ago, I decided to add a 2nd router to my home network. I have a large house and was having connection issues in certain spots. My set up is:
Cable Modem ---(ethernet)--> Airport Extreme --(ethernet)--> Time Capsule
I have the network set up as a single network (Time Capsule extends the network). I followed all the Apple instructions and everything set up with ease and worked flawlessly. I was able to confirm that devices would switch from the Extreme to the Time Capsule depending on location. It was wonderful. Wifi bliss in my home!
Yesterday morning, I showed that I was connected to my wifi network but I could not get any data. Airport Utility showed Green Lights next to my 2 devices but an Orange light next to "Internet" with a status of Disconnected. I assumed it was an issue on my ISP side and went through a modem reboot and some other steps before confirming that I did in fact have an internet connection (hard wired ethernet from modem to MBP). I went through the same steps as before (after restores through the Airport Utility menu) and my wifi network comes back when the Airport Extreme is connected but as soon as the Time Capsule is connected, the Airport Utility shows that I am disconnected from the internet and I have no data transfer.
After hours of soft resets, hard resets, and factory resets including changing the name of the network and resetting/unplugging the cable modem I became convinced that the Airport Extreme was the culprit (I bought it "new" open box on ebay). So I bought a brand new Airport Extreme and the same thing happened. I tried various configurations including taking the Time Capsule out of the equation and going Airport Extreme to Airport Extreme and absolutely nothing works. Bottom line: Once I add a 2nd hard wired router to extend my network, I lose my connection to the internet and it says "Disconnected" at the top point of the Airport Utility. When I have a single router connected, everything works fine (I am using it right now).
Does anyone have any idea what would be causing this? I did not do any updates or anything odd. I just woke up one morning and something that worked for 4 months flawlessly is completely impossible to use.

I figured out the issue and resolved the problem. The Airport Extreme had WAN in from the Cable Modem and LAN out to the Time Capsule and to my DirecTV Home Cinema kit. I re-set up everything with all unnecessary LAN connections disconnected and it worked. I plug in the DirecTV LAN line and it all goes down again. It looks like the DirecTV Cinema device was frozen and causing the issue. Once I pulled the plug and rebooted it, everything went back online.
I have no idea why a frozen DirecTV Cinema device would cause this problem but it was definitely the culprit. Now I have an extra Airport Extreme. Sigh.

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

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.
Follow this link to configure the router with CABLE Internet service.
Follow this link to configure the router with DSL Internet service.

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.

Cannot connect Windows 7 laptop to USB HDD attached to Airport Extreme

I would appreciate anyone's help regarding the following issue. The situation is as follows:
Laptop with Windows 7 installed
Laptop connects to Airport Extreme (5th generation) through Wifi
An external HDD (WD Elements 1TB) is attached to the Airport Extreme's USB
The external HDD is visible in Airport Utility and should work fine, as far as the Airport Utility is concerned
The external HDD is also visible in Windows Explorer and works fine when I attach it directly to the laptop's USB
However, I cannot access the HDD from my laptop when it's connected to the Airport Extreme's USB
I've followed all the steps described in http://support.apple.com/kb/ht1331 for mapping a network drive, so I've done the following:
I opened "Map Network Drive"
I selected an unused drive letter
I checked the Airport Extreme for the correct IP address (in my case: 10.0.1.1) and the HDD for its correct name (in my case called: "Backup")
I entered the correct path to the drive, using the above IP address and HDD's name
After doing all this, I keep receiving the following error message: "Windows cannot access \\10.0.1.1\Backup. Check the spelling of the name. Otherwise, there might be a problem with your network. To try and identify and resolve network problems, click Diagnose."
Details of the error message are as follows: "Error code: 0x80070035. The network path was not found."
When I select "Diagnose", Windows indicates that the external device or the external source does not accept the connection.
Access to the Airport Extreme is password protected. Same for the HDD. However, Windows does not prompt me to give the username and password, which might be causing the problem.
Does anyone have any idea how to solve this?
Thanks,
Paul

If you are connected by wireless.. it is actually wireless that is the problem.
30MB file (please try and use b for bits and B for Bytes.. )
that works out around 300Mb (with overheads).
That is 60Mbit/s average speed.. and for wireless I would say that is pretty good. (Real world transfer speed you can expect 1/2-1/4 of link speed.. and tending to the lower end of that. )
Plug the computer in by ethernet and get a speed for transfer of a single large file.. try something of the 1GB sort of size. A movie file for instance works fine.
Ethernet should be faster than any other step in the process.. assuming gigabit of course.. and that will then give you the upper limit speed.. but I would expect around 10MB/s max speed and maybe a bit less than that. USB on a router is choked because it is processor intensive. Most routers only manage that speed and sometimes a lot less.
Wireless on 5ghz band is faster than 2.4ghz if you are up close. It is worthwhile forcing the 5ghz connection if you want better wireless speed.

I have changed my internet connection to Huawei e586 modem 3g 4g wireless modem my Air Play not working any more

I have apple TV 3rd generation it use to work fine through the previous modem(THOMSON TG585 v7)
I have changed my internet connection now using Huawei e586 modem 3g 4g wireless modem
At the moment There is internet connection in the apple TV I can manage only through the apple remote. But I can’t AIR PLAY or mirroring from iphone
I can see the AIR Play but I can’t play any music or video in the apple TV. Also I am sure I have activated the home sharing in I tunes/Remote app/apple TV
Personally I think because the connection setting,but I do not know how to fix it can someone advise please?

MOG,
I have a similar problem with this HG8245, but I can't even see the airplay icon in my iOS devices nor my MB Pro. However, I discover by accident that it works very well if I connect the ATV through the wifi interface (tested with my iPhone 4 and iPad 3Gen both w/iOS 6.0.1, and my MB Pro w/OS X 10.8.2). But as soon as I connect the ATV through the ethernet port, it disappears from all my devices.
So my guess is that there is some issue (i.e. undocumented filtering) between the wifi and the ethernet interfaces. I have reviewed the HG8245 configuration but I haven't found how to solve this. Have you figured out how to solve it? I will try to use some port scanner to see if there is some difference im using the wifi and the ethernet ports and will post the findings.

MacBook Pro's wireless connectivity with ZTE 531 ADSL modem using BSNL broadband

I have tried to connect macbook pro with BSNL broadband internet connection using ZTE 531 ADSL modem. The connection using both wireless mode and ethernet mode failed repeatedly. Using the same modem, I am able to connect to internet through my Sony Viao running Windows 8 and HP630 running ubuntu (both in wireless mode and ethernet mode). I have tried the 'assist me->diagnostics' option in Macbook's network diagnostics. The first 4 indicators are green, but the remaining 2 (ISP and server) remains yellow. Repeated attempts were made by restarting the modem.
Surprisingly, the Macbook works fine with a newly purchased Dlink N150 ADSL2 modem. I have used the same WIFI settings ( as in the ZTE modem) in Dlink modem also. What could be the reason for this ?

Hello jayan_a_r,
From what you are talking about, it seems like you have done some good troubleshooting to attempt to sort it out. Try using a different Network Location as sometimes that could be an issue when trying to access the internet. Also make sure that modem is using the recommended settings for the wireless access.

Does Leopard server work without an internet connection?

Topic says it all. What a noob question but it seems like it doesn't. I didn't have a network cable plugged to the modem during installation of the Standard Server configuration and it wouldn't continue without an internet connection. Once I plugged it in everything was fine... until my internet connection was out for several hours. None of the services worked during that time and nothing was working right at all.
Joshua.

Hi,
I guess here you may also ask what services the server will host. My experience since Tiger (and Leopard) is that most things involving OD and Kerberos works better (or works at all) if you have a +network with existing DNS+ set up correct before you set up the server. No need of an Internet connection thou.
Have newer tried to set up either Tiger or Leopard as OD master and the first DNS on the network, but I guess (read right: guess) that setting it up as Standalone first, activate DNS and promote to OD master may be the way to go.
But if it will be standalone file server - well. Should work fine with camelots configuration of network.
And why else have a server? If you only have one computer in your configuration? But that may be a totally different story...

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.

WINDOWS ON IMAC NOT DETECTING INTERNET CONNECTION

I RECENTLY LOADED WINDOWS XP ON MY IMAC AND THE INTERNET CONNECTION IS NOT WORKING, MY MODEM IS ON WITH ALL CORRESPONDING LIGHTS ON, BUT IN XP NO DEAL, WHEN IN MAC OS X EVERYTHING IS FINE
PLS ADVISE

Are you using bootcamp or a VM? If you are using Bootcamp did you install the drivers? If you are using VM did you connect the NIC in the VM interface?

Mac, PC, Internet connections, etc... I may be in the wrong place...

Does anyone have an awful time maintaining their internet connection? Please direct me to another forum if there is one on this topic. My settings with Verizon, my ISP, are to the letter.
I need to run Network Diagnostics 6-8 times an hour (sometimes more) in order to reestablish my internet connection. This never happened when I was using a Windows based product.
I thought that it might be the fact that I have a Mac and my husband has a PC, and that maybe there was some peculiar compatibility thing happening, but unfortunately it happens when he is not even here. I'm not eager to call a "geek squad" because I've hear they've done more harm than good.
Has anyone else experienced this? The Genius Bar guy couldn't help me, and my settings with Verizon are what is expected.
Thanks for any help...
Best,
Sheila

The router (if you have one) is the box connected to the modem, which is connected to the internet line-in.
This is the basic setup: Internet connection (like a cable line) -> Modem -> Router -> Computer
If it's only going to one computer, though, you may have something like this: Internet Connection -> Modem -> Computer.
Your problem is almost certainly hardware. Make sure all cords are plugged in (or screwed in, as the case may be) tightly and securely. Check to see if any of them look frayed or blackened at all (which would indicate they aren't working properly). Also, try resetting the connection by unplugging modem (and router if applicable).
The modem will be directly connected to your internet connection. The router will be connected to the modem. The router most likely also has things connected to it (computers, wireless base, or both) unless it is a wireless router.
It's hard to diagnose without being able to see it, but it sounds like a hardware issue.
