Internet sharing using AirPort...

Hi,
I have an iMac and a MacBook... I share the internet connection from my iMac's built in ethernet adapter to AirPort so i can connect my MacBook...
DHCP server on OS X gives to my MacBook an IP address like 10.0.2.X and the other settings.
After some random time period, the MacBook get disconnected and next second connected again but, the IP address change to something like 169.254.XX.XX, the bullet comes yellow and status is writed the it have a self assigned IP address... The connection to the my iMac is reported to work (the AirPort status in menu bar reports that is connected) but i actualy have no conectivity at all...
Trying to set manual IP address and DNS and GW gives no result...
I use WEP encription (40 bit) right now...
On iMac i have Leopard and on MacBook i have Tiger...
Any one can give a clue about what is wrong? Can be a problem with my AirPort module in any of my computer?
Thanks

There is a ethernet connection on my mac pro which is being shared over the airport card in the mac pro with wep 128 encryption. The mbp is four feet away on my desk, getting 5 signal bars for the network and using DHCP to connect (10.0.2.2 is the usual IP address assigned by the mac pro since this is the only other computer connecting to the airport) but periodically just jumps to some weird self-assigned ip address (as reported by the first poster on this thread). This does not seem to happen at my home where I have a different wireless router. I have installed the 802.11n updater for the wireless card on the mbp and other than the EFI firmware updates (which the mbp refuses to install), all the software on the mbp is totally up to date.

  • Internet sharing via airport doesn´t work

    Hello to everybody,
    my problem is, when I do internet sharing via Airport on my imac (OSX 10.6.8) so I can use my ipad for surfing. The connection establishes for a short time and then it breaks down. Once in a while I can reconnect, but it´s constantly breaking.
    I know, this problem is posted a million times, but it still seems not to be solved (or I didn´t find the right thread with the solution).
    Bthw. I phoned the apple support. They wanted to charge € 49,--. Now I´m quite mad at apple. This *****. They are having a problem with their software and they want to charge me? That´s incredible. I can´t understand what´s the hype about apple. Such an awfull bad support they´re giving (or not giving at all).

    OK. To your information. Today I tried the following: I switched off and on internet sharing twice after boot and voila, wifi seems to work fine. Yeah, that´s what I call a sophisticated computer system. Really crappy stuff!

    I've not set up a Bluetooth PAN; a Personal Area Network. Modems and keyboards and such, yes.
    My usual approach here would be a WiFi USB widget, or an embedded WiFi card or a PCMCIA / PC Card or a CardBus WiFi or wired network adapter, or a wired Ethernet connection for the Windows Vista laptop.
    This to connect from the Windows Vista laptop to the AirPort, or into a wireline Ethernet (if there is one). And from there to the Mac Mini server running Mac OS X or Mac OS X Server software.
    As for the PAN, I don't know. I don't have Mac OS X Server running on a box with Bluetooth hardware, either.

  • Trying to share internet connection using Airport Express

    I have an internet connection via a Verizon Wireless broadband card in the Express Card slot in my MacBookPro. I share this connection to my iMac via Airport and I have an Airport Express card connected to a printer & stereo. However, when I establish the Airport internet connection (internet sharing in System prefrences) it establishes a wireless network in the MacBook (I think) as evedinced by the Airport signal (fan) logo changing to a vertical arrow. This precludes connecting to the Airport Express (the Airport Express network is not shown in the Airport pull down menu, only the MacBook network). My question is: can I somehow share the internet connection using the Airport Express network???

    ejagnut, Welcome to the discussion area!
    Configure the AirPort Express (AX) to join the wireless network created by your MacBook Pro. The directions can be found in KB 302153, AirPort Express: How to join an existing wireless network in client mode.

  • Internet sharing via airport woes

    Hi,
    apparantly an thunderstorm fried my ethernet-card in my MBP this morning. Now I am struggling to get internet-access via my iBook G3 which has DSL-boradband via ethernet (pPOE) (either via firewire or airport) but don't succeed:
    1) file-sharing eithert via airport or ip over firewire works
    2) I have set up my iBook to share internet via airport, enabled web sharing as HELP recommends.
    Internet sharing nevertheless doesn't work for me: error message (in network-status) says (translated from German):
    …Airport has self-assigned IP-Address and is maybe not able to connect to the internet.
    I have used the built in settings, changed nithing manually. Any ideas?
    Greetings,

  • Connecting my Powerbook to my iMac for internet sharing via airport

    Thanks in advance for any help.
    I have given up trying to get an answer to my Airport problem and NTL Virgin.
    I now have my iMac connected to web via ethernet all okay for a week now so it can't be my connection that was the problem.
    I need to connect my PowerBook to the internet now at the same time. I would obviously like to do this using wireless technology. I was hoping to web share my iMacs connection via the airport cards on both macs but seem to be struggling.
    I can set up a new network on the iMac and get the PowerBook to see it but it won't connect to the internet.
    Any advice would be great thanks

  • Turning on Internet Sharing via Airport disrupts internet connection!

    I have a very strange problem.
    My iMac G5 (10.4.10) is connected to broadband via an Ethernet cable. Everything works perfectly, Google Earth works, emails come through, internet downloads are perfect...
    BUT!!
    When I turn on my Internet Sharing to share my Ethernet connection via my Airport connection (to let my husband surf the net on his PC) all **** breaks loose on my Mac.
    Google Earth does not function properly, all internet downloads (.dmg) come up with "codec overrun errors", all images sent via email downloaded through Entourage are corrupted, the list is endless. I have to turn off my Internet Sharing, turn off Airport, and then everything returns to normal again.
    Why is this, and can someone help stop the fights my Husband and I are having when it comes to sharing the Broadband connection through my Mac - I don't want to because my Mac goes crazy!
    Ta muchly!!!

    Sorry but an Ethernet hub will NOT properly share the ISP connection. The ISP only gives you a single IP address. If you use a hub (or Ethernet switch), the first computer you turn on will win and get the only IP address. The other computer will not be able to connect.
    To properly share the connection, you need to get a router. The router uses the single public IP address provided by your ISP and creates multiple local IP addresses for your computers.

  • MBP C2D internet sharing over Airport

    I have DSL connected to my MBP C2D over ethernet and want share this connection over the MBP Airport so other computers can wirelessly access the internet. While other computers can see and connect to the shared Airport connection on the MBP, however there is no internet available. I suspect this is because the MBP C2D is using 802.11N frequency and my other computers are G. How can I force the MBP to transmit in G?
    Thanks

    Whatever the problem is, it is certainly not related to the G or N standard.
    Do you have "Personal Web Sharing" enabled under System Preferences-Sharing-Services? If not - try it.
    Under System Preferences - Sharing - Internet review the "Airport Options...", some network names (containing special characters) and encryption settings (40-bit WEP with 5 char password or 128-bit WEP with 13 char password are normally most compatible) can cause problems. On some Windows systems you will need to set the Gateway and DNS IP addresses for the connection manually to point to the shared computer's IP address for Internet functionality to work flawlessly).

  • Re : Apple TV doesn't connect to a Wi-Fi Broadband Internet Service using Airport Extreme

    Hi, using Airport Extreme (Airport Utility version 6.3.2, Internet :DHCP, Router mode : Off (Bridge)) with a Wi-Fi Broadband Internet service. My Desktop (iMac), Macbook,iPhone,iPad join the Airport Extreme Wirelessi network (WPA/WPA2 Personal) easily and Broadband ISP Login-page pops up with username & password options. However, in case of Apple TV (2nd Generation Software : 6.0.2 (6646.81.1)), it connects the Airport Extreme W-Fi network easily but no Broadband ISP Login-page pops up with username & password options. Even using the Ethernet connection of the said Wi-Fi Broadband Internet Service directly to the Apple TV, no internet network connects. Please help.

    There is no way you can handle login details with the ATV and there is probably no way you can do it with extreme in router mode either.. If you need to use a login name and password via a html screen then that is impossible in a device without html.
    But your newest addition confuses me.
    A slight correction in the question : the Broadband Internet Service isn't Wireless, but having Ethernet connection to the Airport Extreme.
    So how do your iphones pop up a login page.
    easily and Broadband ISP Login-page pops up with username & password options.
    The alternative method is to use a computer .. login to your service and use ICS through the computer to the ATV..
    See http://www.youtube.com/watch?v=0jJe_BkQMRc
    Or any site that shows how to route internet through a computer.

  • Can't do Internet Sharing via Airport, laptop PC to iMac

    Help! I'm trying to connect a Windows laptop to my Mac via AirPort to do Internet Sharing. I have Internet Sharing turned on and AirPort is on.
    The laptop PC can see the Mac, but it has a red X and the following message:
    "The settings saved on this computer for the network do not match the requirements of the network."

    I'm finding, after working at it for a while, that "Frank's Computer" shows up as an ad hoc network on the laptop PC and the wireless connection is solid, but Internet Sharing still isn't working. Is there a distinction between ad hoc networks and Internet Sharing? Could it not be working because an ad hoc setting has been made and Airport can't do two things at once?

  • HP3330 Multi Funtion Laser/copier/fax/scanner shared using Airport Express

  • IPhone 3Gs, Mac Pro Internet sharing via Airport connection problems

    Hi, I have internet sharing turned on in my Mac Pro for the Airport connection and it works very well with laptops, but I have trouble getting my iphone 3gs to connect to it sometimes.
    restarting the iphones does not help
    stopping and starting the airport does not help
    I can restart the Mac Pro, but that can be a pain, but does usually allow be to connect again for awhile...

    I've been having the same problems as everyone else here. Trying to share internet connection from my ethernet wired iMac to my MacBook and my iPhone. Tried all the workarounds, but nothing works, or lasts very long.
    Yesterday, I finally talked with AppleCare for over an hour. All their suggestions (trashing preferences, changing settings, etc.) failed, as well. The AppleCare person then put me on hold to speak to an engineer, who told her that Snow Leopard no longer supports Internet Sharing as of 10.6.1.
    Not willing to accept that answer, I had them set up an appointment at the Apple Store Genius Bar for me, and after chatting with the Genius for a while, he also confirmed that Internet Sharing is no longer supported under Snow Leopard. Apparently, there were many hardware issues that the engineers decided to circumvent, and so did not include support for Internet Sharing with the internal airport in Macs. They said that the Airport it is intended to receive, not to send a signals! Yet, it worked fine, doing just that, under Tiger and Leopard! The only fix he could offer was to wipe my drive and take me back to 10.5, which I declined.
    However both the guy at the Genius Bar and the lady at AppleCare inferred that Apple "may" release another update to fix this issue, if they get enough complaints and bug reports.
    So, there you have it. Apple no longer officially supports Internet Sharing in Snow Leopard.

  • Can't find hard drive shared using Airport Extreme

    Hi,
    I just bought a Airport Extreme and set it up to access the internet. However I am having trouble sharing my external hard drive. I followed the instructions in the manuals but can't see or find my "shared" hard drive on my Mac Air or PC?? I have open Finder but there is now shared drop down menu?
    I am fairly new at this so I am sure it is something small I am doing wrong. Hope some one can help me!!

    This set up was suggested to me by an Apple Store employee when I was shopping for my AirPort Extreme and that same employee seemed to indicate that this was how they actually performed their backups at the Apple Store, so obviosuly I was surprised to find information online that states it is not officially supported.
    Yes, unfortunately we've had a number of reports of similar statements by folks at the Apple stores.
    As Tesserax says, sometimes it works, sometimes it doesn't. That's probably why Apple doesn't support it. See Using Time Machine with an Airport Extreme Air Disk (or use the link in *User Tips* at the top of this forum).
    In my case, it worked flawlessly for about 3 months, then every couple of days the backups would come up corrupted. Once, +Disk Utility+ was able to fix it; another time, +Disk Warrior+ could. The other times, the only solution was to erase and start over. Since then, it's worked well, although very slowly on occasion. And that's all with exactly the same hardware, in exactly the same locations. (And the disk is a Seagate Free Agent Pro, too.)
    This forum, and the Time Machine forums, have any number of similar reports.
    I'd strongly suggest you either:
    Return the Airport (and perhaps the disk) to the store. Insist on a full refund because of bad advice, and refer them to the Apple article.
    Take your chances, but by all means keep some sort of secondary backups. See #27 in Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of the +Time Machine+ forum), for some recommendations.

  • File and printer sharing using Airport Express, usb HP Deskjet 3620 printer

    I have a general question, and other forum users might have a good resolution for it - but if not, here's what i'm dealing with..
    I have an Airport Express that I bought a couple of years back, it has all the necessary firmware upgrades, i'm running 2 Windows XP boxes going through a combination of Ethernet on 1 directly to the 2 Wire Home Portal 2701HG-B, and I also have an additional Netgear WGR614 v7. All firmware upgrades on all devices is installed and functioning after reset.. I've tried using a combination of the Windows XP built-in networking software, Apple Airport Utility, as well as Bonjour to get things configured and working right over the network. I've also installed the AT&T software, one is running the Mcafee security suite, and mine (the Etnernet box) is running the diagnostic utility.
    I've tried defaulting all the firewall settings in either/or/all routers i've tried setting the Airport up with, and there still seems to be problems getting file and printer sharing to work right on all computers, and still remain safe behind the firewall. All the network hardware is set up with wpa2/psk authentication, and appears to be configured correctly.
    The only version of the Apple Airport Utility that will run successfully on the systems, is the original version that came on the CD with the Airport. Both systems are completely up-to-date from Windows update, and are both running XP service pack 3.
    I know for a fact, that the Airport is working just fine, as I've troubleshot all possible known hardware issues with it individually, hooked up to 1 pc (with current updates installed and running). Wireless works fine, i'm actually running the Airport utility on my main system in the living room, that's hooked up hardwired to the router. Both systems get online and surf without a problem going through either/or router as well. I've also tried dissabling the Windows firewall on both systems, and trying to set up file and printer sharing manually using the wizard, and that don't seem to resolve the issues either. However, both systems (wheather hooked up networked, OR individually), have both been experiencing some odd "quirks". The Ethernet box i'm on, has overwritten my primary HD, as "Athena" and made it unusable. The wireless box, has been giving simular "boot-up" related errors as well. I've checked the Cmos/DOS settings on both, and performed the suggested "boot-up" priority related tasks, and both systems are still experiencing problems. The Mcafee suite is up-to-date, and has caught several potentially dangrous programs running on the wireless box, hooked up to the Airport Express, INCLUDING the bundled HP diagnostic software.. However file and printer sharing still remains elusive...
    Are there any suggestions about settings to check on the devices, or in the computers, to make sure it's all configured correctly?

    ...Also file/printer sharing just flat out over the network is NOT a problem, as it's been configured before over ethernet through my Netgear router and file/printer sharing worked just fine.
    The main problem seems to be in the Airport Express' settings, it will "get configured" and then lock me out of the utility to where I can't get back in..
    The main Airport password has not been changed, and the wireless network encryption is the same for all wireless devices running on the network.
    The main problem, just seems to be with the Airport.
    Even the Home Portal has detected the Netgear router (unless it having my Netgear router saved in it's settings might be causing a conflict)... Suggestions?
    I've contacted AT&T Home Networking for help already about the Home Portal, unfortunately they can not help me with other network related issues, since i'm not using the 2 wire wireless adapters offered by AT&T...
