Internet Connection sharing AirPort over Ethernet - DHCP not starting

I am trying to share my internet connectoin form my PB17 with OSX 10.4.5. The problem is the ethernet interface is not getting set to 192.168.2.1 when I start the sharing. Also, the client I have connected to the ethernet port is not getting an IP address (yes, is is set to automatically recevice an IP). This is leading me to believe the DHCP server is not starting on the PB.
Internet sharing is enabled
Personal Web sharing enabled
Both enabled in the Firewall settings
The ethernet port is set to DHCP (but I'm assuming that once I turn on sharing it should assign itself an IP address correct?)
CLient set to automatically get an address
Any ideas?

Disregard the msg above. Below is the text I need help with, for some reason I kept getting a message saying I could not edit the above post...

oh yea, if I use my wife's PB15 w/ OS X 10.2.8 it works fine.
Any ideas?

Internet connection via Airport Extreme/router thats not working, why?

I have been having problems with the internet connection via Airport Extreme which I find it a bit unusual and its still driving me nuts! This is what happened:
I have lost my internet connection last Sunday evening upon my return from a weekend away from home. The last time I have used the internet connection on my macbook was the previous Friday morning. Prior to the apparent disconnection on Sunday, I have always used my internet connection wirelessly through Airport Extreme (that is connected via ethernet cable to the NETGEAR DG834v2 ADSL modem which had worked beautifully until the problem arose on my return). This wireless internet connection allowed me to surf the internet anywhere in my home.
However, upon the successful re-connection to the internet via the modem router, I have discovered several new problems. I have tried to set up the internet connection wirelessly again but instead the following happened:
1. Router (Netgear) drops ADSL connection and cannot reconnect when connected to airport via Ethernet. (which is the case when using airport wireless).
2. Router connects to ADSL fine when computer is connected to it via Ethernet. (However, router disconnects when magsafe power adapter is taken out for some inexplicable reason!)
3. Router connects to ADSL fine when nothing is connected to the router (ie. No Ethernet connections)
4. Router connects to ADSL fine when connected to airport via Ethernet and computer is connected to airport via Ethernet.
So from the above, I cannot connect to the internet properly whether wirelessly or not so I suspect it could be faulty router or could it be airport extreme? I have asked my ISP for an explanation and all they have said is that it cannot be the mis-configuration but could be to do with the power adaptors or the way plugs are set up and suggested I take out all the power plugs (and power surge protector) out to switch everything off, the macbook, router, printer and airport extreme. However, when I have re-plugged them all back in, the problems I have described above still persists!
Would appreciate any help if anyone here recognises why this is the case and what seems to be the cause of this. If so, what should I do? Though I have written back to my ISP again yesterday for more help so im waiting to hear from them...
Thanks

Can't connect to Airport over ethernet with XP Home SP3

I can't connect to Airport Base station dual ethernet over ethernet with XP Home SP3. The XP lan connection said Windows could not complete : Renewing your IP address, when i try to repair the connection. the apple Extreme Admin utility shows Base Station Information but can't configure it and said:
The Base station has been reset and is not configured, make sure your computer is configured for a 192.42.249.X-compatible IP address so the base station can be reset to its default configuration. Can any one help with this? I want to set up the airport so I can provide wifi to an IPod but i cant get XP to connect properly it said i have limited or no connectivity.

Its working now but the windows computer still cant get the aiprort base station to start a dialup connection. I dont wnat to usr the ipod for this all the time. Any ideas how to get XP to force the Airport Base Station to open a dial up connection.

Sharing AirPort over Computer-to-Computer Ethernet

As the title says I am trying to share my 17" iMac G4's internet connection (over AirPort) with a 15" iMac G4 over ethernet. I followed the directions over here: http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh914.html but the computers still do seem to be able to see each other. I also enabled Internet Connection Sharing.
I really do not want to shell over $150 for an airport card for the aging iMac. Why is this not working? Could someone give me some specific step-by-step instructions please?
Also it is a normal networking cable not a crossover but I thought the iMac was supposed to auto-detect, does it not?
I hope all of this is clear and I would really appreciate it if someone would be kind enough to help me out.
Thanks

Hy Dylan,
There are 2 different things here :
1. Connect the 2 Macs and verify they see each other (via the Finder's "Connect to server..." for instance)
2. Once they see each other, share the Airport Internet connection from one to the other
Fort step #1, once they are connected by a cable, you need to verify they have an IP address (Network pane in the System Preferences) belonging to the same network. Either you enter it manually (because you have already set up a small home network) or you start the "Internet sharing" and the 2nd Mac will automatically get its address from the first one (the one having the Airport connection). You should the allow "Mac file sharing" (I am not in front of my Mac right now so it is probably not the precise name) in the System preferences Sharing pane.
Shortly after you have done this, the Macs should see each other in the Network view of the Finder.
Once this is achieved, it means you have a working network, you should activate Internet sharing on your 1st Mac and check that you are sharing your Airport Internet connection through your Ethernet network. You can then test it is working by using your favorite web browser and surfing wherever you want.
If this works, then you only have to allow POP (port 110) and SMTP (port 25) traffic on Mac #1 firewall so that Mac #2 cat get and send mail as well.
If you cannot surf from Mac #2, then something is still wrong and I suggest you come back here with some more detailed information about the network addresses and firewalls setup.

Problem with not getting Internet Connect on AirPort Express

Problem with not getting Internet Connect on AirPort Express (version7.6.4). Error says cannot get valid IP address. Have reset Siemens SpeedStream 4100 several time, even with tech support from the big "A" DSL provider. Plug MacBook Pro directly into modem and works fine. Unplugged AirPort, even reset it, still no luck. A bad Express?? or am not looking in the right place to make connection. Was working fine up until Sunday.

Connect the AirPort Express (AX) to the cable modem via Ethernet cable.
In configuring the AX using AirPort Utility:
Under Internet, set the connection to be Ethernet using DHCP.
Under Connection Sharing, set it to distribute a range of IP addresses.
Under AirPort>Wireless, set the Wireless Mode to Create a wireless network, and fill in the remaining settings in the same window. Until you get it working, you might want to set Wireless Security to None.

Problems sharing internet connection through Airport with a PS3

Does anybody know how to share an internet connection wirelessly with a PS3? I've tried everything including following directions from the tech support people from both Sony and my ISP (Verizon) and nothing works. Last time I've talked to Verizon I've obtained a IP number from them as Sony recommended and that did not work either. Is anybody out there with a PS3 sharing the internet connection through Airport successfully? I'd really appreciate any help. Thanks.!!

Internet connection sharing, network printer: not at the same time

Here's the setup:
Mac+airport connected to wireless router connected via ethernet to network printer on wireless network "One".
I want to share my internet connection via airport/"One" with my iPod Touch.
I set up internet sharing, using "One" as the acceptable route. iPod works. Network printer doesn't.
If I turn off sharing, network printer works, iPod (obviously) doesn't.
How do I set it up so I can 1) print to my network AND b) share my internet connection with the iPod?
TIA

Network Configuration Window Freezes When USB NDIS Internet Connection Sharing and Ethernet Port Are Used Simultaneously

Current Setup:
Asrock Extreme 4 Z77 mobo with built-in Broadcom NetLink (TM) Gigabit Ethernet. Windows 8 Pro. Intel i5-3570k (using onboard Intel 4000 HD Graphics). RAID0- 2 OCZ Vertex 4's.
I will refer to this setup as my tower.
The Ethernet port works fine by itself. When I use wired tethering with my Android phone (Droid 4 running on 4.0.4 Ice Cream Sandwich), it works fine when nothing is connected into the Ethernet port in the mobo.
The issue arises when I try to connect both simultaneously. The network configuration window in windows basically freezes and I cannot really navigate it without a ~60 second delay at best.
I would like to be able to accept the internet from my Android via a USB tether and either bridge the connection or use the internet connection sharing service to route traffic through the unused Ethernet port on the mobo (either to another computer/xbox
or more desirably a switch/router to spread to the entire home network). I have extensively researched the issue of Windows 8 become slow and unresponsive when I attempt to do this and I have not found anyone with the exact problem. I am able to
do both the MAC bridge miniport (bridge 2 connections) and Internet Connection Sharing though a Windows Vista (home premium) Laptop I have. The difference between the laptop and the tower I am try to do this on is the laptop has a WIFI and Ethernet connection
while the tower only has the on-board Ethernet.
Do I have all the necessary equipment to accomplish this, or do I need to buy a PCIe WIFI card? If so could I get away with just getting a USB WIFI dongle?
Any help would be very appreciated.

I had the same problem and came here by searching.
Per Rosengren's method solved the problem, but he didn't say how to do it, so I'll try to explain step-by-step for anyone that may venture here.
Open Device Manager (right click on Computer > Manage > on the left side, under System Tools choose Device Manager)
Choose the problematic device in Network Adapters (for me it's called HTC Remote NDIS based device)
Right click on it and choose Update Driver Software...
Click Browse my computer for driver software
Click Let me pick from a list of device drivers
Uncheck the box Show compatible hardware
For the manufacturer, choose Microsoft Corporation
Now you will have two options:
- Remote NDIS based Internet Sharing Device
- Remote NDIS Compatible Device
I chose the second one and it solved the problem, but if it doesn't work you could try the other one. In my case, the driver that was being used was neither of these, but a special driver from Android SDK ADT bundle.
Pick one and click Next. If a dialog comes up, confirm by clicking Yes.
Wait a few seconds for the connection to restart. If it doesn't work, try disabling and reenabling USB tethering on the phone, or reconnect the USB cable.
I should also note that I'm using a custom Android ROM on HTC Wildfire S (unofficial Cyanogenmod). If you have a stock ROM with HTC Sense, maybe this method may not work and you'll need a proprietary HTC driver.

Sharing my internet connection via Airport

I have an Intel MacPro with an Airport card. It is connnected to the internet via one of its ethernet ports. I am trying to share that internet connection via the Airport card with my Windows XP machine. I was able set up the wireless connection using 128-bit encryption, and successully access websites from my Windows XP laptop. However, it seems that neither AIM nor Yahoo Messenger nor MSN IM on my Windows machine can connect via the MacPro internet sharing. I can only use a web browser on the Windows machine successfully. Is there some additional configuration I need to do get the internet connection sharing to handle other kinds of connectsions, rather than just web pages?

I'll admit that I'm merely guessing here. Are you running the firewall on your Mac? It is possible the firewall is blocking the ports that the messaging software is using. If your firewall is on turn it off and try using the Yahoo and/or MSN messaging software. If it now works see if you can determine what ports are being used and edit your firewall to keep those ports open.

Internet connection sharing between Mac Mini and Imac G3- how?

Ok, I'm trying to connect my G3 Imac (running 10.4.8) to my Mac Mini (also running 10.4.8) but it just wont work.
I've turned Internet Connection sharing on on my Mac Mini, and set it to share the airport connection to computers connected using Built in ethernet.
Network (on the M Mini) shows
Built-In Ethernet is currently active. Built-In Ethernet has a self assigned IP address and may not be able to connect to the Internet.
Network (on the G3) shows
Built-In Ethernet is currently active and has the IP address 192.168.2.7. You are connected to the Internet via Built-In Ethernet.
When i try to go to a webpage on the G3 it fails stating, 'You are not connected to the Internet'.
I'm using a standard straight through ethernet cable, as I was told a while ago from apple support that it doesn't matter which u use, straight through or crossover.
Any help would be really appreciated
Macbook 2.0Ghz 2GB 80GB/Mac Mini 1.42Ghz 1GB 80GB/Imac G3 450Mhz 640MB 80GB Mac OS X (10.4.8)

OK after some playing about I can now manage to connect to the mac mini and vice versa to share files.
The iMac G3 now says it has an IP address of 192.168.2.18, and that it's connected to the internet via built-in ethernet. I've set configure IPV4 to Using DHCP.
Except it's not connected to the net.
If i select Using DHCP on the Mini it doesn't obtain an IP address, not even a self set one. So i've set a manual IP address on that, and everything shows up green. Airpot connected to the internet and Ethernet has an IP address of 192.168.2.30.
After reading some forums I set up firewall logging. The result is what happens on the Mac Mini when I use network diagnostics on the G3:
Feb 11 16:43:52 richard-xxxxx-mac-mini natd[394]: failed to write packet back (Host is down)
So I opened port 394 (not really knowing what i'm trying) but it had no effect.

UML290 Internet Connection Sharing

Once upon a time a Verizon Tech helped me set up ICS on my WinXP machines... And, I promptly forgot some of the details. So, I am sharing them here.
Basically, what you will be doing is sharing the UML290 Internet Connection while using the Host Computers Ethernet as the Default Gateway.
BTW, You can rename your Network Connections so that they are easier to keep straight in your head. Right-Click on a Network Connections Line Entry and rename.
On The Host Computer (The one that *HAS* the 4G lte Modem Connected to it.)
On your 4G lte properties, under the 'Advanced' tab, in the Internet Connection Sharing block, check both boxes.
Under the 'General' tab make sure both 'Automatically' check boxes are checked.
On The Host Computer Ethernet Properties, under the 'General' Tab, Use the following IP Address: 192.168.0.1 with a mask (automatically set when you tab out) set to: 255.255.255.0
To set up the Client Computer (The one that the USB Modem is *NOT* connected to) you will need to know the Primary and Alternate DNS servers IP addresses. To do so...
1. Open Network Connections
2. Right-Click on the Modem entry
3. Click on 'Status'
4. Select the 'Support' tab
5. Select the 'Details' button
Copy down the DNS Servers IP Addresses... Then close everrything out.
On the Client Computer select the Ethernet Connection being used to interconnect the two Computers.
You may need a Cross-Over Cable if either or both Computers have any age ont them.
Some newer computers automatically detect and switch over, not needing a cross-over cable.
*IF* your computers can't see each other at all, you need to obtain a Cross-Over Cable.
OK, moving on... Under the General Tab: Select Use the following IP Address:
IP Address: 192.168.0.2
Mask: 255.255.255.0
Default gateway: 192.168.0.1
Close out of all property boxes...
Bring up your Browser and see if it can find Google or any other site you need to get to.
Hope This Helps...

VZAM sometimes does not unload properly, so it's running even if you don't see it. You may see one (or even two) instances of the process in the Task Mgr. You can kill it and restart it. One reason it takes time to start and stop is that it has to wait for Wireless Zero Config service to stop so it can take control of WiFi connections. When it exits, is usually restarts WZC service.
You can also set yoru VZAM prefs for manual startup of the program and connections. In this case if a connection is lost, you may have to manually re-connect.

Slow internet connection via AirPort on MacBook running 10.5.7

The internet connection via AirPort on my MacBook is frustratingly slow, and I have no idea why.
I have an AirPort Extreme connected to a Virgin Media cable modem, a new iMac and a two year-old MacBook, both running 10.5.7. No problems at all with the wireless connection on the iMac - I get the full near-10Mbps download speed I'm paying for, despite the fact it's at the other end of the house. Not so on the MacBook, where I get barely 2Mb, even if I'm sat next to the router.
I've had other AirPort problems since the 10.5.6 update - notably one common to a lot of people on here, it seems, of the AirPort dropping the wireless connection every 2 mins. This was only 'fixed' by the fairly drastic workaround of essentially abandoning my user account and connecting via a different one.
For the slow internet problem, I've tried resetting the PRAM, turning off my cordless landline phone, changing the wireless channel - to no avail. I can't test the wired connection as my MacBook doesn't recognise my Ethernet port, it would seem, and hasn't for a long time.
Can anyone help? Thanks in advance.

I assume that you meant NVRAM as PRAM is not used with Intel-based Macs. Regardless, network settings are not stored here and resetting it won't really help. The fact that your MacBook is not recognizing the built-in Ethernet port is telling me that may have an issue with the system board ... that may be showing up as poor performance with the AirPort as well. I suggest that you take your MacBook in to your local Apple Store to have them take a look.

My computer keeps switching its internet setting from Airport to Ethernet without me doing anything. How can I fix this??

My computer keeps switching its internet type from "Airport" to "Ethernet." As my computer is not connected to an Ethernet cable, the ethernet does not work, and so I lose internet connection every time it does this. And it does this two or three times a minute (no exaggeration). This means that, by the time I've changed the setting and refreshed my page, the internet type has changed again, and I'm back to square one.
So far, I've tried the following:
-Reordering the list of priorities on the "Network Preferences" page
-Going to the Ethernet "advanced" options and switching everything to either "off" or from "automatically" to "manually"
-Rendering the Ethernet inactive
-Finally, I created a new location with only airport on
Usually, doing these things makes the problem go away for a day or two, and then it just comes back again.
It's not a problem with the internet itself, as this has been an ongoing issue for the past few months, and I've switched locations three times since then.
Does anyone know how to make my computer stay on Airport, and NOT switch to the Ethernet setting all the time?

Hi samanthaspunt,
I would first try these steps:
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/HT1430
If that does not help, I would try un-syncing and resyncing the music via this article:
iTunes: Syncing media content to iPod

Internet Connection - Your Apple wireless device does not have a valid IP.

I just bought an Apple TimeCapsule and set it up normally, following instructions to my Arris cable network on the Videotron provider here in Quebec, Canada. The TimeCapsule did appear as a wireless device on my MacBook Pro (after updating the AirPort software from the provided CD - as was instructed). I went through the whole installation process to obtain at the end this error:
Internet Connection - Your Apple wireless device does not have a valid IP.
The only provided instructions were to check the cable and then contact your Internet provider. Well it seems clear to me that if I contact my provider and say that the internet connection works fine directly on my computer, also fine through my "normal" wireless router but not with my new TimeCapsule, I won't get much of a response.
After a lot of research, a friend indicated the solution in my case.
You have to really reset the cable modem to convince it to start giving out IPs again.
To do this:
1. Unplug your TimeCapsule (possibly you might have to reset to factory defaults - see the documentation)
2. Unplug your cable modem
3. Reset your cable modem by pressing the reset button with a pen (or something) for several seconds.
4. Plug your cable modem back in and let it reboot/restart - until the lights are back on.
5. Plug in your TimeCapsule
Everything should now work and you can restart your AirPort set-up on your Mac.
Good luck!

My ISP is AOL. The service is DSL via a broadband modem. Somewhere during the setup process there appears to be a communicatiosn issue between the Airport Extreme Base Station and the DSL modem. When I hook the DSL modem directly to my iMac I can connect to the internet without any issues.
I tried the factory reset and the DSL modem reboot process described in other posts and seemed very close to success...until the internet setup step. That is where this issue first presented itself.
