Which one shoud do DHCP; Airport Express or Wired DSL Modem?

I have a wired DSL modem for my internet connection, and just purchased the Apple Airport Express to provide wireless to all 3 computers on the network (2 Mac, 1 PC). Which piece of hardware do I want to do the DHCP? I think right now it's set up on both, but I'm not sure. Any advise?

DHCP server is responsible for allocating IP addresses to the computers on your private network. In order to avoid duplicating addresses, you can only setup one DHCP server per subnet. It makes sense to set up the DHCP on the router that's also running the NAT (Network Address Translation), this will ensure both functions are going to use the same private IP address range. It will also simplify IP address reservation, and port mapping.

  • @ Airport Express and BEWAN DSL MODEM : no internet ..why ?

    Hello,
    I connect a BEWAN ADSL Modem to my Airport Express and create a Airport network to have internet access for my Ibook.
    I have choose "Ethernet" for Internet access with DHCP parameter.
    Here's what i see : the Bewan ADSL modem give to the airport a public IP for the ip address (that comes from my Internet Provider), a netmask and a router ip that is 192.168.1.1.
    On my Ibook, i could connect to the airport (printing is ok) but I couldn't have internet access : blank page under Safari...
    My Airport Express has the last Firmware....
    I think is a trouble between the BEwan ADSL modem and the Airport because I have Internet access when i directly connect the Bewan Modem to the Ibook.. a routing trouble ?
    Do i have to manually enter IP parameter of my Airport ?
    Have you the same configuration ?
    Thanks for helping me fast.

    ouba john,
    I'd recomend trying a reset and reconfigure. Your setup sounds pretty simple. Hold in the reset button on your AE until the light blinks, let it restart, and choose your unmodified Airport express from the drop down menu. Run Airport Setup assistant from the Utilitiies menu and try to let that program do all the tweaking for you. Once it's up and running, you can go into the wireless settings with Airport admin and reconfigure security if you wish.
    This is "just give this a try" advice. It seems I've heard odd things about ADSL modems, so good luck

  • Airport Express to Verizon DSL Modem - Connectivity issue

    I have Verizon DSL at home. I have an iMac G4 1.2GHZ w/o internal wireless. I'm trying to use the AX to join the DSL Wireless, and use the Ethernet on the AX to provide internet access to the iMac.
    Setup:
    Verizon DSL modem w/ build in Wireless G
    MAC address authentication
    AX MAC added to the MAC list
    AX Sucessfully added to DSL Wireless (I can see it connected at the DSL modem web page
    AX Status light is green (confirmed its getting an IP from the DSL Wireless)
    iMac plugged into the AX via ethernet (confirmed its getting an IP from the AX)
    No internet access on the iMac however.
    I did notice in the Airport Utility that sometimes the AX is logging:
    Connected to: <insert mac address here>
    Disconnected from: <insert mac address here>
    over and over at times....
    The AX and the Wireless router are approx 15ft from each other.
    I've also powered everything down, fired up DSL Router 1st, then AX, then Computer. Still no dice on internet to the iMac.
    Any suggestions? I shouldn't have to add the iMac MAC address to the filtering...but maybe....didn't have time to try that lastnight/thismorning.
    Thanks for any help!

    Welcome to the discussions!
    Couple of thoughts here:
    Check AirPort Utility - Manual Setup
    Click the Wireless tab just below the icons
    Make sure there is a check mark next to "Enable ethernet clients"
    You are trying to use the AirPort Express in a configuration known as a ProxySTA.
    The modem/router will need to be compatible with this function, so you should check with your ISP to see how this could be enabled on your modem/router.

  • Can I use the Airport Express as a cable modem?

    I am trying to set up wireless internet in my home, and I am planning to purchase an Airport Express. Can I use the Airport Express as a cable modem, or do I have to purchase a modem from the ISP and then connect the AE to the output of the cable modem?
    Thanks,
    Adrian

    No, the AirPort base stations do not perform the functions of a DSL or cable modem, so you will still need to acquire one.

  • Epson printer using airport express connect wired to PC

    Hi,
    I have a problem with my epson printer C41 series.
    It is connected using USB to Airport express then wired using ethernet cable to my existing router in order to share to 3 computer (2 PC, 1 PowerbookG4).
    Firstly, I used bonjour to detect the printer, and it was working perfect unfortunately under my PowerbookG4. So I unplug the powerbook, just want to use airport as printer server. I ran bonjour again, it detect the printer under my airport, but it doesn't work when printing.
    Perhaps you could help my problem.
    Thanks in advance.

    I have a cable modem (Comcast) connected (WAN) to my
    Airport Extreme Base Station. Question: Can I us an
    AirPort Express to "join" this network (plug it in in
    another room) and use the LAN port to connect an
    Ethernet cable to a computer's Ethernet port?
    If you "Join an Existing Wireless Network" the ethernet port on the AX is DISABLED. If you set up a WDS network using the AX to extend the range of your AEBS, the ethernet port will be ENABLED.
    Will
    the AE LAN port have a local IP address ( i.e.
    10.0.1.5) available for a wired Laptop to connect to
    the internet (or even attach a non-wireless internet
    web camera)?
    Properly configured as a WDS network, the device connected to the AX ethernet port will pull an IP address from the AEBS, just like any other connected device. You can also configure this connected device with a static IP address, outside the range of the dynamic DHCP addresses.
    I hope this is not too basic......

  • Can u run Airport Express and a wireless modem together?

    Can u run Airport Express and a wireless modem together at the same time?
    I'm using AE purely for music distribution and have just bought a wireless modem for the internet (not a AE). However I can now only select either the AE network, OR the wireless internet network (it's BT HomeHub). Hence I can either play music or use the internet, but not together!
    Any ideas anyone..??
    Thanx
    David

    You should configure your AirPort Express (AX) to join the wireless network provided by the modem. The instructions are in KB 302153, AirPort Express: How to join an existing wireless network in client mode.

  • How do I set up my Airport Express to my Viasat modem, which requires a DHCP connection, without getting a double NAT connection error?

    I have an Airport Express connected to a Viasat 4100 satellite modem. This requires a DHCP connection and is connected to my Airport Express by Ethernet. I then have three computers (two running Mavericks and one running Lion) and two IPhone 5s and an Apple Tv on the network. If the Airport Express is set to DHCP and NAT then the network works and I have internet, but the amber light flashes and I have a double NAT error. If I use it in Bridge mode the airport express goes green but I have no internet. How can I set it up so it works properly? If anyone knows could they please give all the settings I shoud use on the Airport Express as I may have left incorrect setting on it whilst trying to fix the problem. I have checked and it has been confirmed that I cannot change any settings on the satellite modem.

    Go into AirPort Utility, click on the AirPort Express, and click on the "Double-NAT" error. Click Ignore. There's nothing that can be done about the Double-Nat unless you ignore it (no harm) or contact your ISP and get them to change your Modem/Router into Bridge Mode, and even then can't guarantee that you won't get that error.
    Again, best thing to do: Ignore the Double-Nat Error.

  • The internet coming from my AirPort Extreme, which is extended by an AirPort Express and my Time Capsule, is being very flaky. It is dropping and I have to reconnect every few minutes. Any solutions?

    To be more detailed, my AirPort Extreme needs to be extended by an AirPort Express, which then is extended to my personal Time Capsule. The internet drops on my MacBook Pro and other MacBook Pros randomly. We then reconnect with no problem and go on with what we were doing. The internet is fine. Always able to connect. We have Open DNS set up as well. But the flaky internet is annoying. Any ideas how to fix this?

    The primary issue that you will need to contend with is the distance between routers. 300' would be at the fringe of the signal coming from the base station located in the house which, most likely, make it too "weak" to extend/repeat with the second base station at the shop.
    There is a method to configure a relay base station between them in a Wireless Distribution System (WDS), but a WDS has two major drawbacks: 1) It can only operate in the 802.11g Radio Mode, and 2) For every base station participating in the WDS, the overall bandwidth will be cut in half .., so with a total of three (main, relay, & remote), the maximum of 54 Mbps (for 802.11g) would be more like 15-17 Mbps. If you plan on streaming HD video (either 720p or 1080p), your local wireless network may not have enough bandwidth to do so successfully.
    You proposal to run the DSL line to the shop does offer another option. Instead of running a DSL line, run an Ethernet cable between the house and the shop. You would connect one end to any of the available LAN ports on the AirPort Extreme to the Ethernet port on the AirPort Express. You can then configure both base stations into a roaming network and not have bandwidth loss of the WDS.

  • One Time Capsule & Two Airport Express for Range Extension but will my time capsule hard drive be accessible to all the user on network ?

    I am planning to buy 2TB time capsule which is [2TB hard drive + Airport Extreme] and two Airport Express to extend the range of my wifi network. we have a large family & because of that we have 1 macbook, 2 laptops , 2 desktops, 4 iphones, 2 ipads, 3 android phones, 2 apple tvs, 2 ps3's. all of these devices are on my Wifi network but some of them are off usually ps3, apple tv and desktops computers r off but still their is alot of traffic. Now i am buying this 2TB time capsule instead of Airport Extreme so that i can save money by getting 2TB hard drive for me only & not the whole family so i want to know if i can keep the hard drive private & at the same time i want to share my internet connection with all of these devices which belongs to my family members, will this be okay ? and they wont be able to access my hard drive ? & will i be able to access my hard drive if i m connected to any of those two airport express & not the main time capsule. indirectly i will be connected to time capsule by using airport expresses in client mode correct me if i am wrong 

    You can use TC with whatever wireless you currently have.. if it works you should not need to buy a pair of express as well. The best method is to bridge the TC and plug it into the main router.
    You can certainly keep it private for your own access only.. simply set a disk password only you know. Easy.
    As long as you have a single network, then wherever you connect in the network will be able to access the TC.. but also note file speeds to the TC with multiple wireless hops will be terrible slow.
    Also note all security on the TC is an illusion. It is a home device.. press reset and anybody can then access it. You can even get past disk password. If you want security keep the device off the network.. use an external hard disk plugged directly into the computer.

  • Best All-In-One Printer for MacBookPro & Airport Express

    I want to buy an all-in-one color printer for my office. My main computer is a new MacBook Pro with the latest OS, and my network runs on an Airport Express. I want all of the computers on the Express network to be able to print, scan, fax. etc. through the wireless network. I want a work-horse printer that has a low cost-per-page to print, I don't need a photo-quality printer. Any suggestions? I can't get my current HP LaserJet 1320tn to work at all through the Express.

    Read the reviews & system requirements of all the printers you are interested in purchasing.  My personal preference is Epson. 

  • Audio drops only on one of my two airport express

    I recently added another airport express to my network and the audio drops randomly while the first airport express never does that...
    The one that works well is next to my cpu and the one that does not work well is about 30 feet away. Moved the cpu closer but no luck.
    What to do ???

    If your Airport Express devices are configured to "join" an existing wireless network, what is important is the distance (and type of obstacles) between your Mac and the main base station, as well as the distance (and type of obstacles) between the Airport Express and the main base station - not the distance between the Mac and the Airport Express.
    Another factor influencing the quality of the connection is radiofrequency inteference - yes, even if one Airport Express works just fine.

  • Only one speaker working with Airport Express

    Hi,
    Hoping for some help. I just connected an Airport Express to my stereo but only one speaker (left) is working. I plugged in headphones to the jack in the AExpress as suggested in other postings and both left and right work there. I have checked and updated Airport Extreme base station and Airport Express firmware software.
    I have an older amp (connecting the RCA cables to the TAPE ports since there is no AUX) but both speakers work for everything but the AirTunes.
    I am hoping there is a fix since I would really like this to work.
    Thanks for any suggestions.

    Thanks for your response and sorry for the delay in
    responding. I did take the first set of cables we got
    (Y-adapter 2-male to 1-mini) back because we thought
    that was the problem. However after I exchanged for a
    new cable we have the same problem. I am thinking
    that the chances are that we would get 2 sets of bad
    cables are pretty slim.
    In both cases only the red cable worked for both
    speakers but if we only plug in the black cable into
    either speaker channel in the amp you can faintly
    hear the music and some static.

    Did you ever get the problem with airtunes just playing through the one speaker? I have the same problem...reckon it is a faulty input port on the express. Did you try an optical cable? It might work as it works differently.

  • How does one recover a lost Airport Express password?

    Both on my iPhone and iPad I can use the wifi signal at my friend's house, so they both have stored the password for her Airport Express. My friend, however, needs to re-enter her forgotten AE password to use her own AE. Me not good with technology, so how can I get my iPhone and/or iPad to display the password so that I can provide it to her?
    Thanks,

  • Hello, is it possible to have airplay play one album on my airport express and to listen to another album on the local mac?

    No.

  • Need Help with 5 Port Switch, Airport Express, and wired iMac

    I recently purchased an airport express to accomodate my laptop's wireless capabilities. However, the airport express has only one ethernet port, as does my parents' modem. Thus, I could either hook up the airport or my parent's iMac. I chose the airport, which resulted in a few weeks worth of fights. To alleviate the problem, I purchased a linksys 5 port group switch, after someone told me I could use that to hook up both at the same time. Initially, the iMac wouldn't work. It registered what I was told was an invalid IP address. Then a cable technician came by, reset the modem (unplugged the battery), and now the airport does not work; it flashes yellow and says that it cannot detect the ethernet signal. 
    The iMac is running OSX 10.3 and the laptop OSX 10.4.  I am not sure if the modem can only accomodate one IP address or if there is any way to share IP addresses. Do I need to change something with the DHCP on my laptop? Do I need to manually enter an IP? Any help would be greatly appreciated. I'm completely lost....and without wireless internet.

    Instead of a switch you need a wireless router, because your modem will only assign one public ip address to the switch and that ip address will be forwarded to any one computer at a given time...You should replace the switch with a wireless router and it should resolve your concern...
