Two network connections simultaneously?

Hi,
I want to do screen sharing with presenters, so I can use SnapzPro on my MacBook to record their screens on their Mac. Can the Mac that is presenting be connected to my Mac via a crossover cable, and to the wireless network via AirPort so they can access the internet? The reason for this suggestion is that when I tried to use a wireless network with ARD, it was far too slow (screen redraw once every minute or two), so I'm wondering if I can use a crossover cable between my Mac and the presenter's Mac and then use ARD 2.2 to do the screen capture, while the presenter's Mac is also connected and they can use regular internet access via AirPort.
Can a Mac have two simultaneous network connections like this?
Any ideas/comments?
Thanks,
Russ Conte

Yes, the Mac can be connected simultaneously to both ethernet and Airport. And, as C.Moser indicated, any G4 class or newer machine will auto sense the direct connection.

  • How to establish two ethernet connections simultaneously?

    Hi!
    I have a two-ports router. The first port via ordinary RG-45, and the second port via usb interface.
    I want to have both of them to be connected simultaneously. I done this at Gentoo, but can't to do at Arch.
    So, what I done exactly:
    I found and loaded usbnet module: modprobe usbnet. After that I written appropriate values for new interface (eth1) in /etc/conf.d/network
    interface=eth0
    address=192.168.1.7
    netmask=255.255.255.0
    broadcast=192.168.1.255
    gateway=192.168.1.1
    interface=eth1
    address=192.168.1.70
    netmask=255.255.255.0
    broadcast=192.168.1.255
    gateway=192.168.1.1
    At this point I restarted networking: systemctl stop/start network and checked for new interface:
    ip addr | sed '/^[0-9]/!d;s/: <.*$//'
    and got output:
    1. lo
    2. eth0
    3. eth1
    OK, I decided to test new interface:
    ip link set eth0 down
    ip link set eth1 up
    eth1 started succesfully. But I can't to start eth0 back: 'ip link set eth0 up' does nothing, even I stopping eth1
    I tried to reboot and checked eth0 again: eth0 gone. No more eth0...
    ip addr | sed '/^[0-9]/!d;s/: <.*$//'
    1. lo
    3. eth1
    Second interface that was eth0 is missing. And I can't get it back.
    Where is eth0 and how to connect both interfaces simultaneously?
    Thanks in advance for any help.

    I'm assuming the "two devices" are actually the 1 router (via Cat5 and USB), and that the router is also acting as a bridge between those 2 interfaces.
    That's my understanding of the OP's situation anyway.
    That will not cause a switching loop. STP is enabled by defualt on a bridge device and will take care of that. The packets will only use one inteface, until one link is down. Then the packets will use the other interface.
    EDIT: Hum, really the OP didn't really give us enough info.
    The way I read it was that the Arch computer is a Router with 2 interfaces 1 RJ-45 and one USB-to-RJ-45. Then that's it. He didn't say anything more about his network. So, origonaly thought that he must be wanting to connect to other computer to this "Arch Router"

  • Using two network connections at the same time?

    Dears,
    I have two available Internet connections:
    1- a DSL connection which I'm connected with AirPort to,
    2- and a 3G USB modem connection (Huawei E156G if you need to know) which I setup through Network Preferences.
    Can I specify anywhere which connection an application should use at a given time, or all the time?
    For instance,
    a- Safari and Mail should use exclusively (or at first try) the AirPort connection,
    b- and iGetter (for faster downloads) should use the 3G connection
    Let me point out that I setup the 3G modem in Network Preferences (and that's the way I connect to it).
    By the way, if someone has trouble (which I had) setting up the Huwaei E156G on Snow Leopard, I can help.
    Thanks in advance for any help.
    Abdelaziz

    By default, the top-most service in the Network preferences gets the internet connection. All internet related traffic is sent on that interface.
    As far as using both for internet at same time, I'm not sure how to do that. You might search for setting up routes. Routes in the network tell it to send certain things to a certain interface, but I don't know how to differentiate a download from web surfing, etc.
    You might also want to try posting that question on the [Unix|http://discussions.apple.com/forum.jspa?forumID=735] forum.

  • Routing Applications through two network connections

    I have a network wireless card which I use for internet and at the same time I use the airport to access the network printers in the LAN. When I try to make a remote desktop connection it goes through the wireless card and I need it to go through the airport.
    I tried making airport the first one in the list, which solves the problem of connecting to the remote desktop, but then I cannot not access internet.
    Is there any way one can route a certain IP address to go through an exact connection?
    Thanks in advance for your help.
    Maria

    Network routing is based on destination IP address, not per-application.
    Therefore it is not possible to tell Application A to use one connection while Application B uses another.
    It is, however, possible to send all traffic for a specific IP address over one connection or another, but it won't matter which application tries to access that address, they'll all go the same way.
    However, for the most part, this happens automatically. Since you only have one default gateway address on your system, the interface that gateway is associated with will be used for all non-local traffic, while each interface will handle the traffic for its own subnet.
    What this means is that if your wired ethernet port is configured for 192.168.1.x/24 with a router address of 192.168.1.1 while your AirPort link is set for 10.1.1.x/24 then any traffic for anything in 10.1.1.x will go over the AirPort and anything else will go over the wired port.
    The only reason to override this would be if you had a different router on the 10.1.1.x network that you want to use to get to specific addresses. For example, if you wanted to route to 123.45.67.89 via a wireless router at 10.1.1.1 you'd run the command:
    route add 123.45.67.89 10.1.1.1
    now all traffic destined for 123.45.67.89 will go over the wireless link to the router at 10.1.1.1 rather than the default router on en0.

  • Connectivity to two networks simultaneously?

    Hello!
    A co-worker has a new 27" (early December) iMac (10.8.5) with one Ethernet port, two Thunderbolt Ports, and four USB ports. This replaced a G5 tower (10.6.8) with two Ethernet ports, etc.
    While on the G5, she had no problem maintaining connection to the company network (for file-sharing and internet connection) and to a local plate-writing station (for printing purposes) that was set up as a second network. (IT staff didn't want it on the company network.)
    The set-up we have going for the iMac now is to use a Thunderbolt-to-GigaEthernet adapter for access to the company network/internet and the Ethernet cable to the second networkl/plate-writing station. Thus, in the Network Preferences > Location: Automatic,  we've pointed the Thunderbolt port using Automatic DHCP to the company network and the Ethernet port with Manual settings for the IP, Subnet, and Router to the separate plate-writing station.
    Our problem is that when she works with one, she loses connection to the other!
    Our solution at present is to set up two separate Locations in the Network Preferences so she can toggle back and forth between the company network and the plate-writing station as needed. But she uses both frequently and running to the Network Preferences all the time is a bit of a hassle—especially since she had simultaneous access to both as needed on the old Mac.
    Is it possible with the equipment have to maintain two simultaneous connections between the two networks without toggling between one or the other? How would we do that? Or is there a better way to set up the preferences? Or have we maximized our available options?
    Let me know if there are parts to the puzzle I seem to have left out. Thanks for looking in!

    Hi,
    I have, in Mavericks, had the need to maintain an Airport/wifi Connection to another Mac whilst using Ethernet (instead of Wifi) on this Mac.
    We had a power cut and the router suddenly stopped doing WiFi.
    The MacBook Pro I have was further away from the Ethernet hub so I Shared the Internet using Ethernet to Wifi.
    I had not tried it but I am sure I could "Share" from the MacBook Pro over Ethernet ( direct cable) and maintain the WiFi the iMac normally uses.
    Thunderbolt can do many things.
    It can support hard Drive and Displays as well as "Bridge" connection to a network.

  • Is there a way to connect to two networks simultaneously?

    Here is my scenario:
    I am an audio technician who travels from venue to venue for work have to constantly switch between two networks to do my job.  I use MAC OS w/ the most current version 10.9
    Example:
    99% of the time, there is venue provided wireless internet via DHCP, w/ no wired option available.  I log onto it for all my internet related productivity.  At the same time, I need to stay connected to a manual/static ip local network to remote & monitor audio hardware (wireless mic's, dsp drives, mixing consoles, etc).  I have the ability to use either a wired or wireless connection for the local manual network (new airport express, or wired line). 
    I go to my network preferences in my system prefs and can see a green confirmation indicator that both networks are indeed connected.  However, depending on which network i give priority to by "setting service order", the other network drops.  For example, today Im using a wired line to remote/monitor my audio systems on my manual/static ip network and can stay connected as long as i set my ethernet connection at the top of the 'service order' list.  As soon as I go to launch my Safari browser it says I am no longer connected to the internet, eventhough my network system preferences show I am still connected.  The only way I can get the internet to connect is to reset the 'service order' and put wi-fi back on top.  As soon as I do this though, my manual wired audio network loses it's connection.
    I should note some settings.  Today's networks:
    wireless (internet):
    ip: 10.100.1.159
    sm: 255.255.0.0
    router: 10.100.255.254
    wired (audio network):
    ip: 192.168.0.128
    sm: 255.255.255.0
    router: 192.168.0.1
    Is there a way to stay connected to both, regardless of the 'service order'?  I have a brand new airport express if putting something like that in-line helps in anyway.
    Best,
    Brian

    There can only be one active connection at any given time, no matter how many networks you may be connected to.

  • Connecting to two networks at the same time

    Hi Kadin,
    I am looking for the same answer for a long time. I have two situations that requires to connect to two different metworks and that is when I travel with my portable Linksys router WRT54GC .
    1. I stay at a hotel with a wireless Internet network connection and I try to use the network to access the Internet and then (2) I also need to access my external Maxtor harddrive to which I am connected through my portable router WRT54GC .
    2. I have an almost identical situation but instead of the hotel network now I have a brand new T-Mobil cell phone made by ITC, which is called Wings and it uses a new way to connect my laptop to the Internet by using a Windows Mobile 6 Internet-share connection, which basically connects my laptop to the T-Mobile network and assigns it a IP address.
    The problem that I have is that in both cases I can connect to each one of the networks separately but not simultaneously.
    Any advise as to how this can be done. I also tried the Wireless WET54G as a bridge with similar negative results.
    Thanks,
    Pole

    Ok not real clear on your setup, but here is the "networking answer" why you can not connect to two networks.
    A device must have an IP address on the same subnet of the device you want to establish a connection or an IP route must be known to the network routers, since your internal address are most likely in the reserved private range, no internet router is not going to know how to deliver the packets to the correct hosts.
    the simple answer is assign a secondary IP address to the network adapter on your laptop.
    In the windows IP address properties for secondary address you can not set a default gateway. Windows only has 1 default gateway.
    good luck

  • Connecting two networks.

    I am trying to connect two similar networks. I am not sure if this is possible or not.
    My network has cable internet access through a Airport Extreme wireless router to a hub that connects to all of my devices (iMac, Xbox 360, TiVo, Win XP computer). The other network also connects to the internet through a cable modem and has a linksys wireless router. My iMac connects to my network through ethernet and the second network wirelessly.
    I can connect to either network separately. I would like to be able to transfer files and print to the other network while simultaneously logged on my network and accessing the internet through my modem.
    Is this possible? If so what do I need to do?
    Thanks,

    It is possible, but what would really be the point? For the possibility, you could simply have one network connected via ethernet cord, and the other network be strictly wireless. The only reason to even have two networks would be bandwidth issues, which you would want to have your non-computer (but internet reliant) on one network, and then have your computers connect through the other network. Transferring files between two networks at the same time wouldn't be the most efficiant method, simply having both computers connected via ethernet would be by far more effeciant.
    Airport Extreme/Express is limited to 54 MBps realitivly. You would get much better speeds via ethernet. If your trying to get more data faster by transferring via ehternet and airport, then you may want to keep in mind that speeds are also limited to hard drive speeds.
    In short, its pretty over-kill.

  • Connect to two networks, ethernet(LAN w/o internet), wireless(w/ internet)

    so i'm trying to connect to two networks, a wireless and a wired one
    the wireless(which connect to an access point) is a network which allows me to connect to internet, and the wired(regular router) one is a small home local network, which does not connect to internet.
    if i just have the wireless one on, unplug/disable wired one, i can connect to internet just fine, but if i do plug in ethernet cable, then all of the sudden i can't connect to internet anymore.
    in my Network Coonections window, it does show that the wireless one has "Access to Network and Internet" while the wired one has "Access to Network only". I'd assume that the computer is smart enough to find its way to internet, but apparently not.
    is there a way to set a preference, so vista tries to find internet conncetion thru wireless first, before go on to the wired network?
    I konw this is technically possible, because on my mac, i can set in such way that it takes certain connection first
    thanks in advance

    I think I am getting it but still no joy.
    On the WiFi connection to FIOS Router I have manually set metric to 1.
    On Same PC in Ethernet I have removed gateway and set a metric to 10.
    Before I did this connection to Internet was very slow when the Ethernet cable plugged in and Interface Enabled. After removing gateway and setting metrics access to Internet AOK.
    I have working Homegroup, network printer but no Internet access from Hardwired PC.
    Cannot ping FIOS router @ 192.168.1.1 from hardwired PC. Destination host unreachable.
    NMAP Quick Scan 192.168.1.* never sees 192.168.1.1
    So, I'm still not routing properly.

    Hello ianbroste. Welcome to the Apple Discussions!
    In order to "combine" networks, your 802.11n AirPort Extreme Base Station (AEBSn) would have to be configured to extend the wireless range of your neighbor's router. This would (potentially) only work if his router is also another 802.11n AirPort.

    Just go to the wireless network preferences and empty out all the stored wireless networks.. then scan and connect to the local wireless.
    Select them and tap the - button below it.
    Once they are emptied out.. it might be good to reboot the computer with the remember networks unchecked.

    I have purchased two movies on the store that at the time were unable to download, due to a full start up disc. I have now freed up the space and the remainder of the movies won't download. It gives me the error code 8003. I have a good network connection and the space for the movies, but cant seem to get it to work. Anysuggestions? It doesnt even let me delete the downloads and start again.

    1. iTunes won't offer cloud downloads for songs that it "thinks" are in your library, even if it "knows" the files are missing. If you've exhaustively searched for the missing files and there is no prospect of repair by restoring to them to their original locations, or connecting to new ones, then delete that tracks that display both the missing exclamation mark and are of media kind Purchased/Protected AAC audio file. Don't hide from iTunes in the cloud when asked, close iTunes, then reopen. You can download from the cloud links or iTunes Store > Quicklinks > Purchased > Music > Not on this computer > All songs > Download all.
    2. Why? Not sure, perhaps 3rd party tools or accidental key presses combined with previously hidden warning messages when trying to organize the library. There is a hint that using the feature to downsample media as it is synced to a device may also be involved, though I've not replicated it. Whatever the reason a backup would protect your media.
