    Is it possible to share my internet from Wifi to wifi. Act as a wireless router but getting internet from wifi too?

    No, that's sharing from Ethernet to Wifi. I need Wifi to Wifi.

    I am not positive but I believe it you would be able to do what you are wanting it will either be through the internet share, but you might require another dongle to make it happen. I would think that an airport express or another similar device would be the better and more efficient design and for rather cheap as well.

    I don't believe this will be possible as the wifi radio can only connect to one wifi at a time and I doubt it can connect to one and create it's own at the same time either.

    What use case do you have? there may be a better solution.

    I'm sure you have a good reason but right now I'm hard pressed to think of one... It seems to me that any time your mac could connect to wifi, the other devices could too.

    Hmm well I suppose you're right, I think you can share wifi via bluetooth though.

    Yeah, I'm trying to think of a reason why he could sign on the Mac but not the other device and I'm not coming up with anything.

    A computer can sometimes pick up a wifi signal that a small device like a phone can't pick up at all.

    If the wifi available is of poor strength - but enough for the Mac to pick it up - the Mac could potentially re-broadcast the wifi to the phone, acting as a wireless repeater. To rebroadcast the wifi using wifi would require the Mac to have a USB wifi dongle in addition to it's internal wifi. It appears it can be done with Bluetooth but I've never tried this.

    It's actually for my 3DS. It can't understand my schools security for the wifi, so I have to repeat it from my mac.

    As others have pointed out, and I can confirm, it's not possible using only the built-in wifi. You do have some options, however.

    1) Connect to the school's wifi using your Mac, then share the connection over ethernet. Plug a wifi access point (or router set to access point mode) into the ethernet port. Connect your DS to that.

    2) Buy a USB wifi card. Share wifi from your internal card to your USB card. Connect the DS to the USB card.

    EDIT: Note that both of these methods can be detected by your school's IT department, and both are usually against your terms of service. If the school decides to crack down on this, it is entirely possible that you will be caught, and some schools have been known to disable a student's internet access for a semester (or longer) as punishment for TOS violations.

    some clarifications

    Hi,

    The conditions to share "WIFI over WIFI" are:
    1. Your WIFI chip can open more than one channel.
    2. you have a software router that will work in Access Point Mode.
    3. the operating system must be capable of handling the above 2

    I have a MBP from 2010 with bootcamp running windows 7 and I can share my WIFI (provided by the hotel) to create my own WIFI hotspot that I use with my tablet and phone (and even my colleague in the next room). We save a lot of money with this.
    so condition 1 is fine with "recent" mac computers.
    I fulfil condition 2 with a software router called "Connectify" (sorry not mac version)
    Condition 3 is fulfilled as I use windows 7 (previous version of windows won't support it)

    But I haven't been able to find an equivalent mac os setup or separate software to do the same on mac os.

    This will do it. But as an IT guy in a school, I can say your school's tech probably won't be too fond of this setup if he finds out. Not only are you intending to run a rogue AP (which can cause interference for other wireless clients), but you're also connecting an unapproved device to the network.

    I have been searching for about a half an hour trying to figure out how to use my MacBook Pro as a "WiFi repeater—" i.e. it receives a WiFi signal and subsequently allows me to wirelessly connect my smaller devices to the internet. The reason I need to do this is because my laptop can receive WiFi signals at greater distances than my other devices.

    WiFi to WiFi cannot be done as far as I have seen (I would be curious to know why, as it seems Macs are capable of this on the hardware side).

    Behold, the answer: WiFi to Bluetooth. Go to System Preferences —> Sharing —> Internet Sharing. Share from WiFi to Bluetooth PAN. You can now receive a weak WiFi signal with your Mac and hook your iPad, etc. up to the internet via Bluetooth.
