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).
HTH,

  • Internet sharing over wireless

    Didn't see anyone post this but is anyone else having problems with Internet Sharing over wireless?
    Trying to have the macbook connect to the iMac over wireless and use the iMac's wired internet connection. On the iMac, the Airport card is on, and in network preferences, internet sharing is turned on. However, the options for sharing over wireless is grayed out and I can't get into those options to customize it. On the macbook, it doesn't see it in the available networks list to connect.
    Am I missing something? Do I need to "create a network" on the imac now? I didn't have to do this in 10.4.10

    After much consternation and countless trials I finally have everything back up and working. Here is what I did finally to get it to work. (Note that I am not a network configuration expert - I am only reporting exactly how I have it configured and it works without complaint).
    1. I trashed my \Library\Preferences\System Preferences folder and restarted my Mac since I had updated from 10.4 and I wanted to start from a fresh set of preferences. ( I backed up that folder separately)
    2. I opened the Network Preference pane and configured my Ethernet connection (connected to my external AirPort Express which I am using as a wireless router to my other computers) as follows:
    -Configure: Using DHCP
    -IP Address: 192.168.0.197
    -Subnet Mask: 255.255.255.0
    -Router: 192.168.0.1
    DNS Server: 192.168.0.1 (grayed out and so I am not sure what this means)
    I set these settings by clicking on the Advanced button.
    Under the TCP/IP tab I had chosen:
    - Configure IPv4: Using DHCP
    (This set the IPv4 Address, Subnet mask and Router)
    - Configure IPv6: Automatically
    3. On the Sharing Preference pane, I configured the following:
    -Share your connection from: Novatel Wireless EXPD (because I have a 3G wireless connection; otherwise I would have chosen the standard Internet connection)
    -To computers using: "Ethernet"
    And then I turned on the Internet Sharing Service and confirmed in the pop-up dialog that I wanted to share my Internet connection.
    4. Using Airport Utility, I configured the Airport Express by first clicking the Internet button to show the Internet Connection page and set the following:
    - Connect Using: Ethernet
    - Configure IPv4: Manually
    - IP Address: 192.168.0.179
    - Subnet Mask: 255.255.255.0
    - Router Address: 192.168.0.1
    - DNS Server: 192.168.0.1
    - Ethernet Wan Port: Automatic (Default)
    - Connection Sharing: Off (Bridge)
    I also configured my Base Station and Wireless with names and Passwords.
    I then clicked Update in AirPort Utility and after it restarted everything magically worked!
    I think that the problem lay with my original IPv4 settings where I had chosen DHCP rather than Manually hoping that everything would automatically be set as it had worked previously. The clue was that on my MacBook Pro I noticed that the DHCP was not enabled when connected to the AirPort Express. Even my iPod Touch is now connected to the Internet!
    If anyone can explain all of this I would appreciate it.

  • How to Internet sharing from AirPort throuhg Ethernet

    Hi! How to Internet sharing from AirPort throuhg Ethernet?

    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.

  • 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!

  • Problems sharing internet connection over airport

    Hi everyone-
    I've researched the heck out of the forums and still cant figure out what's happening with my system. I've got a MacBook Pro with OS 10.5.2. In previous OS versions (10.4) when I was successfully sharing my ethernet internet connection, the airport icon in the status bar showed a vertical "up" arrow, indicating that my connection was being shared.
    I'm trying to do the same thing in OS 10.5.2 but not succeeding in getting the same notification. I'm finding that when I access the "Sharing" folder under "System Preferences" and select "Share your internet connection from: ethernet" and "To computers using: Airport" that both settings grey out, the "Internet Sharing" button turns green and the status says "On", but no sharing occurs. I've checked using other wireless laptops and a wifi finder, but no signal from my MacBook is ever found.
    I've deleted my preferences folder to start fresh, no help. I've tried sharing from different ethernet sources, no help. It just feels like the problem is in the OS somewhere, not with the internet connection.
    Any insight or help would be greatly appreciated! Thanks!

    seems like i got the same issue as u and i just posted it:

  • 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,

  • 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.

  • Trying to connect a replay to my MBP using internet sharing-need help

    i'm trying to get my replay system connected to the internet thru my MBP. the replay has a nic and of course, the MBP has the airport card. i've turned on internet sharing from my airport to the ethernet. however, the replay can't seem to connect to the net. i do not have access to the router to get any settings. i do the routers ip address, the MBP's ip address, and i think i have the correct dns servers for the isp here. i can manually enter the above info but i'm not entirely sure what goes where. do i treat the MBP as the router in this situation? does anyone have any experience with this? thx.

  • Internet sharing over ethernet

    My iMac here is sharing my dialup internet connection over ethernet.
    my iBook is set to Configure IPv4 using DHCP but it's getting an IP of 192.168.2.12 and the subnet 255.255.255.0 and the Router 192.168.2.1.
    But the iMac isn't even connected to the internet yet? o.O it's a crossover cable directly between the two computers so there is no other computer on the network. Airport is off on the laptop and I don't own a base station yet.

    The computer gets its IP address from the router not from the Internet. If you have Internet Sharing turned on, then your iMac is acting as a router and providing an IP address to the laptop via the Ethernet cable connection.

  • 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 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?

  • Printer/Internet sharing over ethernet not working

    Due to unsolvable problems with Airport and 10.5.2, I've decided to set up an ethernet network between my Mac Pro and MacBook. I have an ethernet cable going from the ethernet 2 port on my MP to the MacBook. I am able to establish a file sharing connection, so I know that the cable is working.
    However, I cannot get printer sharing or Internet sharing to work.
    I have enabled printer sharing in Print & Fax preferences, and selected the USB printers I want to share. But when I go to Print & Fax preferences on my MacBook, although I do see my printer when I attempt to add it the preferred driver does not show up and it selects "generic postscript" instead. This is completely strange, because when I go through the same process when the MacBook is connected to my Airport network (when it isn't dropped out), I am able to add the printer with the correct driver without a problem.
    As far as Internet sharing goes, there's nothing happening at all. On the MacBook when I open Network preferences it says "Built-in ethernet isn't connected". I don't know what I'm supposed to do to get this going. I already have enabled Internet Sharing on the Mac Pro ("share built-in ethernet 1 connection with computers connected to ethernet 2"), but I don't know what to do beyond that.
    Do I need a switch?

    sure, there are workarounds. I was trying not to spend any money!
    Mostly I am curious what caused it to stop working.
    Thanks for the input!!

  • 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.

  • Poor internet speed over airport

    my daughters 20 in ch 1.8 Ghz iMac G5 is incredibly slow over airport.  It has the built in aircard and is running off a Linksys B/G router.  it is the only machine pulling from that router most of time, sometimes the Wii runs off that router.  The connection is usually 3-4 bars, but the speed is miserable.  The aircard only sees 3 networks, however sitting my MacBook next to it, I can pick up 7-8 networks (3 are in our house.)
    Is the reception just generally this bad on an iMac? Anything I can do to help it?  wrap it in aluminum foil...
