Want to check local wifi hotspots with network card

I've been told that my new MacBook Pro comes with a wireless network card and that I can use it to check whether there are wifi networks around.  Is there a way find out info on local networks with my Mac?

Well, it's not technically a card, it's built in, but it's easy.  First go to System Preferences (it's under your Apple Menu, top right corner), then click on Network.  Along the right side is an icon that says "Airport".  Click on that.  Then check off "Show AirPort status in menu bar".  On your menu bar, then you should see something that looks like a signal (which shows strength).  If you click on that, you will see all the hotspots near you.

  • How to create adhoc Wifi Hotspot with iPhone to connect Apple TV for Mirroring and Airplay?

    I don't want to use my iPhone to share or tether my iPad or laptop etc. with my cellular data plan.
    What I want is to create a hotspot with my iPhone (or iPad) so that I may connect my Apple TV to the adhoc network so I am able to stream video and music from my iPhone to the Apple TV.
    I do presentations in front of live audiences and want the ability to mirror my iPad or use Airplay to stream video and photos to the Apple TV without connecting to a public WiFi network.
    The apple TV is so small, I just tuck it into my bag with an HDMI cable and I am able to tap into LCD projectors and flat screens and use keynote or video from my iPad so my audiences can see my presentations.
    Seems pretty simple. But I cannot activate a hot spot on my iPhone without signing up for AT&T's service. Fact is, I have no need to tether my iPhone or iPad, I just want to create an adhoc Wifi network solely for the use of my Apple TV.
    I posted this question to the iPhone discussions as well, but thought someone here has wanted to do the same thing.
    Someone suggested just bringing any WiFi router and connecting devices to that. But that's not a solution. It's about mobility and simplicity and not creating a larger footprint.
    Thoughts?

    I am a presenter and I do what you want to do.  I use an apple tv as the presentation device that connects to the projector. The thing that makes it all work together is the Apple Airport Express $99 and looks just like the APple TV but white:  http://store.apple.com/us/product/MC414LL/A?fnode=MTY1NDA0Mg
    Basically you define a wireless network ahead of time (using your iPad or iPhone and the Airport Config App) and let your iDevices connect to it and know the details ahead of time (so they will auto connect later).
    You have a couple of options of connecting the airport express to the apple tv.  I basically stacked them and used an ethernet cable but you can define the wireless connection also.  I then strapped them to the projector (which I travel with) and used an HDMI cable from the apple TV to the projector.
    Sometimes I present from my iPad...sometimes I present from my iPhone.  Sometimes I present from my iPad but use the remote app on the iPhone to see the next screen.  Now with Mountain Lion you could even present with a Macbook Pro (not needed though)
    Wanna hear the coolest thing?  When I want to demo something on the iPad instead of just showing the screen remotely using Airplay I use an App on the iPhone called Air Camera directed down at my iPad screen.  The Air Camera sends the video to the Apple TV using Airplay and people are able to see my taps by seeing my fingers.
    Another cool thing in a classroom setting with other iPads you are able to let people know your Wifi password and then display their iPad screen up on a projector to ask a question about something or demo something.
    So for the extra $99 dolars for the Airport Express and a few minutes setting it up, wammo you have it!
    One last note.  If you actually do have wired internet at the podium you can connect it to the WAN port of the Airport express and all your iDevices would in addition have internet access.  If you need internet access for all the devices and you are presenting in a place without internet then you have to bring a wireless hotspot in place of the airport express.  This works equally well (again just setup the connection from the iDevices to the wireless hotspot ahead of time)
    Have fun and good luck!

  • Issues with creating a wifi hotspot with Macbook Pro

    Hello. I am staying in a hotel with others for an extended period of time. There is only one ethernet port. I have previously used the ethernet via internet sharing to turn my macbook pro into a wifi hotspot. I went through the steps this time (checked, double-checked, and triple-checked via various websites), and though my computer says that it is broadcasting, AND all the other devices (iPhones, other laptops) can see and connect to the network, no internet seems to be coming through the broadcasted connection.
    What I mean is, the network exists, and when others connect it shows full signal in their airports, etc, but they still can't connect to the internet. Pages won't load, my iphone tells me that it's "not connected to the internet" even though it has full wifi bars. Is there some important step that I'm missing? I am running Snow Leopard.
    When I did this before, I feel like there was some other strange option I either had to enable or disable, but that was a long time ago and I can't recall. Right now, I just go into internet sharing, set "ethernet" as broadcasted from, and "airport" as broadcasted to, then I name the network and click "Start" and everything seems to work, except for the not actually being connected. Can anybody explain this?

    I can indeed get on with just my Mac, as can my roommate (he also has a Macbook Pro). I have not tried turning off my firewall. That may do it. However, I do not know how to turn off my firewall. I could just google it, but I figure I'll ask y'all anyway.

  • Need help setting up WiFi - Xfinity with Network Switch, Time Capsule, Airport Express and Apple TV

    Hello - I recently got Comcast Xfinity service.  We had switched from a different service.  Our wifi service was never great, but prior to Xfinity, it worked decently.  But now that we have Xfinity, our wifi is much worse and very unreliable.  I am seeking advice on how to setup my various Apple wifi devices in my home.   I have attached a diagram that illustrates what I am dealing with.  We have a large old house with stone walls.  Comcast does not support this issue. 
    To explain the attached diagram, we have a total of 4 levels in our house - an unfinished basement, 1st floor, 2nd floor, and 3rd floor.  The Xfinity router is in the basement and it is connected to a NetGear 10/100 network switch.  I already have ethernet cables running from the network switch in the basement to various locations throughout the house.  So I have ethernet connected to my time capsule and ethernet connected to each of my 3 Airport express devices.  The dark lines running from the network switch to the various devices represents ethernet cable.
    The immediate problem that we are having is that we are unable to connect to our wifi networks.  The networks show on my mac laptop and my iPhone, for example, but I am unable to connect.  I know that I am inputting the correct password, but most of the time, we cannot get in.  Sometimes we can..... Very frustrating!  Also, due to the fact that I setup what I have over several years, I have multiple network names.  I once tried to fix that issue, but was unable to tackle it due to my lack of understanding.
    Here is what I am looking to accomplish:
    1. Seamless wifi access throughout our house.
    2. One name for our wifi network.  Right now we have multiple names for multiple networks.  Just want to simplify and have only one network.  (I guess that an additional "guest network" would be ok, but not absolutely necessary.
    Also, if you think I should disable the Xfinity wifi, and just rely on my mac wifi devices, I am perfectly fine with this.  Just tell me how to do so.
    I have no idea how where to start or how to set this up.  I imagine that I would need to disconnect everything and reset and start from scratch?  Can someone tell me what I should do?  Even general advice would be helpful, but the more specific, the better, given my limited understanding.  Any help or advice would be greatly appreciated.
    Thanks in advance!

  • Connect iPad 2 wifi to wifi hotspot with joikuspot

    I installed joikuspot light in my nokia E71, and my iPad recognized the wifi hotspot but I still can't access Internet. Pls help

    I also had the same problem, but I realized this person (Baltax) who shared in this forum how to resolve this issue. He is a god-send.

    Had the same problem; I connected with the device but couldn´t browse internet. Turned out to be an encryption issue; to make it work I used (in the settings for Joikuspot) WEP open, ascii, 128 bit, and let Joikuspot create the password for me. Using this it worked flawlessly.

  • Create WiFi Hotspot with Command Prompt?

    I was trying to create WiFi Hotspot on my Windows 7-32bit running laptop using the command promt method after followinng the instructions from here >> http://www.techswatch.com/2014/11/create-wifi-hotspot-windows-87-command-prompt.html However, the problem is, after creating the hostpot, when I enter the password it does get connected but I cannot access the internet. I am sure that I have entered the correct password else it wouldn't have got connected. Any idea what could have gone wrong or if I need to follow anything else? Any help would be apprecited. 

    I think it is better to use Wi-Fi creator to create WiFi in laptop. Search 160 WiFi in Google!

  • Can you get wifi hotspot with iphone 5

    i would really like wifi hotspots but the problem is i cant find it on my setting menu, how can i get it and also i am on tesco mobile uk lol

    You mean "Personal Hotspot" ?
    If you do not have the setting menu then the Hotspot is probably not supported by your Telephone company or by your Data Plan.
    Or your phone does not connect to WiFi ?

  • PCI USB2 Controller card conflicts with network card

    I've installed a PCI USB2 controller card since my motherboard (IWill K266-R) only has support for USB1. However, the card seems to conflict with one of my network cards, because traffic on the internet-connected NIC is very slow, and often drops completely. Traffic to and from the other (local) NIC seems to work fine, though.
    I have tried moving around all three cards in different PCI slots, I think I've tested almost every possible combination by now. I've also tried disabling as much as possible in BIOS, such as onboard sound, serial and parallel ports etc. I've tried lowering the FSB.
    For now, I've removed the controller card, and is using the USB1 ports on the motherboard instead. This is very frustrating, though.
    Does anyone have any suggestion on what I can try next? I've browsed forums, both this and others, but I haven't found any more hints on what to try. Could there be some setting in Arch that could affect these sorts of things?

    "I guess the ATA100 card will work fine correct?"
    If you mean large drive support, it may provide that or may require a firmware update to do so. You should check the manufacturer's web site for specifics. All ATA-133 cards do provide 48-bit LBA for large drive support. I'd return the Ultra ATA-66 card to the eBay seller, although many refuse to pay for return shipping, even when the mistake is their own, either through ignorance or deliberate misrepresentation. In cases such as this, it's sometimes more cost-effective to swallow the loss and keep the incorrect part.
    "Will adding a jumper apply for a ATA100 card as well? I'll need a blue and gray ribbon correct?"
    If you use an 80-conductor ribbon cable with color-keyed connectors, set the drive configuration jumper to CS and connect the drives to the cable as you wish (in terms of physical placement in the computer). If the ribbon cable doesn't have color-keyed connectors, set the jumper for the device connected to the end connector as Master and the drive (if any) connected to the middle connector as Slave.

  • Solaris9 x86 problem with network cards, ACPI, IRQs

    Hello!
    For the last two days I've been trying to solve the problem of Solaris9 x86 not being able to use my network card. I have tried with 3c905CX-TX-M, RealTek 8139 and Realtek 8029 and none of them works. The problem is the following:
    Everything is properly configured, networking etc., but the cards can only send and cannot receive packets. When trying to ping, the packets leave the NIC but none of the reponses are detected by NIC. When I check with 'kstat elxl' I can see that 'intr' is zero, and out_packets is increasing as it's sending packets.
    From the discussion forum I can see that this same problem has been known for several years. One of the conclusions is that Solaris x86 sucks at dealing with IRQ setup and that the best thing is to disable ACPI and 'PnP OS' option in BIOS. However, I've tried all releases of AMI bios and none them has neither of those options. I have played with various priority levels in BIOS but all that has accomplished is that the card, when first started, captures a few interrupts/packets but then stops again. This is usually just enough to finish the ARP exchange (arp -a shows the remote host).
    And of course, all the cards work just fine in WindowsXP and Linux. And all the cards work nice in another PC which runs the same Solaris 9 x86.
    My motherboard is Gigabyte 7VTXE. (The other one in which it works is ASUS P2B-DS).
    I would really appreciate help!

    I had almost identical problem today on an HP Kayak - which happened to be dual CPU one. The fix
    set pcplusmp:apic_forceload = -1
    in /etc/system worked for me. The only drawback is that it also leaves the machine single CPU. AFAIK this (downloadable) S9x86 kit is licensed only for one CPU anyway, so I wonder if something has been fixed in the code to make sure it is not run on multi-CPU systems. Before the fix, mpstat showed thousands of interrupts on CPU0, both CPUs were constantly busy at about 70% and there was no network connection on a number of cards I tried (3Com 90x - elxl, Intel iprb, another one with Realtek 8139 was never recognized, so I did not bother too much to find if there is a fix for this); pinging out resulted in the hub port light blinking, nothing comes back.
    Anyway, the fix is good enough to test s9 for now; everything else seemed to be OK. If it may be of some use for somebody, don't go into the disk option of the Solaris Management Console; the machine in question had Windows 2003 server (RC2) installed before Solaris9, the disk tool decided that there was no label on the disk and asked to write it on; I clicked the 'cancel' button, but the partition table was irreversibly damaged, so I had to start from installing W2k3. My guess is that tool has been tested only with Sparc, so there is no issue with BIOS level partitioning there. BTW, system info of the SMC insists that the CPUs are Sparcs...

  • Want to use my mac as wifi hotspot with 3G USB connection

    Howdy Folks,
    I'd like to try an alternative to my local internet provider, which has now increased to $240/mo for less than 2mb/sec service. (I live in a remote place with just one provider)
    The local cellular company offers 3G USB internet "sticks", and I would like to see if I can use that to tether my MacBook Pro as a hot spot.
    And, better yet, is there a way to expand that to my Airport Extreme?
    Or, use the USB connection on an Airport Express directly?
    Anyone know a solution(s)?
    I have a small cafe, so the purpose beyond personal use, would be to provide WiFi access for up to about 6 additional users.
    Thanks in advance!

    Ok, thanks. I'm still confused. So I turn Wi-Fi off and I try to select "personal hotspot" under "cellular data" and I get the following message: "wifi is off - personal hotspot will only be available over Bluetooth and USB. Do you also want to enable it over wifi?" Then it gives me two choices 1) Turn on Wifi  or 2) Bluetooth and USB Only. If I choose 1 like I did today the bluebar appears but it's connected over a crappy wifi network...if I choose #2 the blue bar never appears and the ipad isn't a hotspot???

  • Public WiFI Hotspot with Terms of Service and Stats?

    c1114 wrote:
    Check out this company. Several years ago i set up a small switch at a garage that wanted their customers to have wifi and of course separate from their network. The actual wifi signal was provided by a Linksys wrt54g plugged into the switch.
    http://www.guest-internet.com/
    Hmmm I'm looking at some of those. The main drawback would be that they limit the bandwidth on most models. We have a 100 Mbps fiber line, and I would have no problem with WiFi using up to 50% of that, so we would be looking at one of the pricier models.

    So two questions really.First one:I'm curious, those of you that provide wifi to either the public or employees, do you have a "terms of service / usage agreement" page that users have to agree to before they are given access? Why / why not? What are the legal implications of not having one? Let's say citizen Jim gets on my free wifi at our library and downloads a virus. Can he sue us if we don't have some kind of disclaimer and terms of use that he had to agree to?Second:Those of you that use a captive portal with usage terms and that do stat counting, what provider do you use? We're thinking about switching next year, because our current one has been very spotty. Being a public library (that means we are POOR), cost is obviously the biggest issue. We just need to be able to log how many total sessions on the wifi, length of sessions,...

  • How can i create wifi hotspot with WPA for windows laptops?

    No, not unless Apple introduce it for the iPad 2 in a future iOS update - but until if/when that happens you won't be able to use it as a personal hotspot.

  • HT2589 I want to check on purchases made with my credit card

    I want to know how to check purchases made on my credit card

    You can check the purchase history on your account via the Store > View Account menu option on your computer's iTunes (though I'm not sure if that shows auto-renewing subscriptions) - there should be a Purchase History section with a 'see all' link to the right of it. That will list free and paid-for downloads, and if you've use gift cards to purchase items then it won't distinguish between how they were paid for.

  • Some wifi hotspots are invisible for nokia 5800

    my problem is that some wifi hotspot are not visible for my nokia 5800.
    I know the wifi hotspot is there because I can connect to it with mij laptop.
    Also, a friend of mijn can connect to the wifi hotspot with an HTC telefon.
    I can easily connect to my home wifi and other hotspots without any problems,
    but some hotspots just won't connect.
    For one particular hotspot, I know it doesn't use mac-filtering and doesn't
    require fixed ip adresses. And I was able to connect to it in the past, but
    it is invisible now.
    what could be the problem and how can it be solved?

    checked the filtering list, no networks are filtered.
    the problem must be something else.
    as I said, laptop sees hotspot, my friends HTC sees the hotspot, Nokia 5800
    sees the hotspot sometimes, can connect sometimes, but when connected
    gets error message (gateway can not be found - something like that).
