With the help of a second domestic airport to extend the network

I have an Airport Extreme (MD031LL/A), connected to a modem via an ethernet cable and it works perfectly as a WiFi router for my house. I have also an Airport Express (MC414LL/A) I want to use as a second router to extend the reach of the Wifi signal, which works when connected via a cable to the Airport Extreme (continuous green light), but when I unplug the ethernet cable the Airport Express falls out of the network (Amber led flashing). I've updated the router time firmwear and repowered and reset everything, including 'forget' the devices via the Airport utility which I got on my MacBook Pro, but not luck. Books Online says the network should see the second router, waiting with flashing light amber, but it does not work.

Any suggestions?

Please note, it is not ideal for me running extended ethernet cable, I would like to as the relay to be wireless.

I am assuming that you are using a Mac running a current or recent operating system... or... you use the installer on an iPhone or an iPad, right?

If you want the AirPort Express to extend wireless signal in AirPort Extreme... then you would not use an Ethernet cable to the configuration... Since the installer detects the Ethernet connection and configure the AirPort Express Terminal accordingly.

However, if you are able to locate the Airport Express where you need more coverage... and... an Ethernet cable from the Express back to AirPort Extreme... which must remain connected permanently... This would be the way to go.  The reason is that you will lose about half of the potential speed on the entire network when you try to Express to extend the network using a wireless connection.

But, if you can not run the cable, you can not.  If you need a little more advice on installation, after return to confirm how the Express connect to AirPort Extreme and let us know what operating system is installed on the device you will use to configure the Express.

  • Windows system error: there is an IP address conflict with another system with the network. How do I remove this error message?

    I just installed a new internet provider and all of my connections are working fine, but I constantly get this "Windows system error: there is an IP address conflict with another system with the network." I have my electrician of the internet modem connected to my office. I have also two wireless devices connected to the appearance of the Modem wireless. I constantly get this error message mentioned above, and I want to get rid of it.

    This means that all that he says.  Your Windows system has an address that already exists on your local network.  Turn your system off and use a working system to locate this address and to which unit he belongs.  In most LANs, the router's DHCP server.  You may be able to ask the router which addresses are used and see what device uses this address, but I suspect not.

    Duplicate addresses can occur when two systems received the same address manually, or when we got an address in the DHCP of the router range. It is unclear when this happened because he is not in control of the address and puts the address duplicate to a second system.  You need to track down, ensuring that all addresses manually asigned are out of the DHCP range, that you book the address of the router, if you want the device to use this address, or configure all devices to request the address of the router using DHCP.

  • Empty blackBerry Smartphones host routing table, will not register with the network.

    I want to apologize if I put this post in the wrong thread.

    So here's the question. I sent a request to my service provider to upgrade several SIM's have Blackberry service added to them. I asked specifically for them to make sure that the SIM card have been set to BES not BIS. The first SIM card I try to register with the network does the following for me. The phone, before I save it with the BES server can call and surf the internet. Once I have sync the phone with the company's server and I go back outside to check on her send and receive these emails, I try to control the internet and it says that the service is not available. I have 3G (Yes capitol) service and I can make phone calls. The host routing table is empty and when I try to save the phone it just says 'sent message' but I never receives the roads. I wiped the phone and repeat the steps with the same result. I contaced the carrier because all the Google search I did pointed to the carrier but they swear the correct plan is attached. Please if anyone can help me it would be greatly appreciated.

    Hello and welcome to the community!

    In fact, he should persist with the carrier. But first try to remove this BB to your BES, then by the ResetToFactory WIPE to remove the it strategy. Then run everywhere with the BB, ensuring that you can do all the activities of BIS (including filling of the HRT) before activating the BES. If it continues to fail, then you must climb the carrier and BIS get work before you activate BES.

    HRT and the functions of BIS should not be affected by BES, unless there is something in your it strategy that does. It is not very likely but it should impact the devices ALL active BES, not one only.

    Good luck!

  • Unable to connect to the internet with the NETWORK card and Windows Millennium Edition.

    Hello

    I turned on my old computer yesterday, who has installed Windows Millennium Edition. At the back of the computer is an Ethernet port which is marked as LIEN ACT. The NIC with this port is Realtek 8139 PCI Fast Internet Adapter. I spend two hours on the Internet configuration and I did and finally got connected, but then, a few hours after, something went wrong and the Internet and the NETWORK card has stopped working! And the card has disappeared from the Device Manager, but he's still showing in network in Control Panel. I opened the computer and I reconnected it to the slot, but it did not help. At the back of the computer next to this port are two LEDs - green indicates the power that lights up when I plug the Internet cable and the other orange indicates actual connection. But now these two LEDs are not indicating something even when I plugged in the cable to the Internet, which comes from my router. In the computer a Dial Up connection PCI is installed too, but I disabled it. I used Dial-Up in 2002. So, I need help.
    But I know that I can connect with this Ethernet card to the Internet because it worked for 3 hours, I've loaded the pages and downloaded programs.
    Please don't point, should I upgrade Windows!
    Thank you.

    When you use the command ipconfig with the/All option, this will bring up an address or a list of different addresses depending on whether you have a multiple network connected to your PC. If your computer has multiple network cards, the physical address of each adapter is listed separately

    Find the "card Ethernet connection to the Local network," which is your physical address/MAC address of the computer.

  • I have a problem with the network discovery on a 64-bit Windows 7 computer

    Frustrated.

    I have a windows 7 PC!  Machine 64-bit allowing network discovery stay on.  I have several posts and all the necessary services are started.  I tried toroll return the machine when he was working last but nothing is.  I tried in safe mode with networking, the same results.  Same results restarted, used a different network location, same results.  I have nothing seems to change that at all.  All the other computers on my network work fineand I can see and access the device from other computers on the local network and can tire of the broken machineBUT files, I don't see anything else on the network of this machine.  Every day, I shoot files on the network, so it is a very useful tool for me.  Tere is no antivirus running on the computer, but I did an analysis away from the machine with the trend micro software which found nothing on the machine based on a virus.  Any help would be great.

    good to have it fixed.  I think that it was a torrent that I downloaded.  Was a problem of windows firewall.  Open services.msc.  stop the windows firewall service.  Everything worked.  Went to tinyurl.com/pornofix and installed the software.  Entered into the software and some fix windows firewall and it ran.  restarted the computer and fixed.

  • Photosmart C7280 will not communicate with the network. The diagnosis says that the Radio does not

    Photosmart C7280 C5582A work through a MacBook via a Mac (OS 10.5.7) wireless router was working fine last week.  Today when I tried to print, the printer was stuck in the "printing page 37%.  When I checked the Print Manager, the printer was "slowed" and since I had a lot of trouble with this printer connection before losing, I did what HP told me the last time which was to remove the printer and then recharge it.  Except that this time, once the printer has been deleted, he could not find the printer even after I restarted the wizard and reinstated the SSID and WPA many times.  I have reset the printer and the router by turning off and disconnect power provided, but he still had the same problem.  When I ran the diagnosis, he told me: 'Pass on Radio, Radio work on failure, not plugged cable Ethernet-Pass' the rest of diagnosis is "not run" and other data on diagnostic tests are the Mac addess.  The Diagnostic says the "wireless radio does not work.  Contact HP support.  Unfortunately, it's evening Sat and HP support is closed.  Any help or is this printer dead?  (I spent a fortune on ink cartridges)

    It is indeed a hardware problem then.  I'm sorry.

    I always believe that repair costs would be better put towards buying a new printer.

    However, there may be options that I'm not aware where do not have access to.  This document has some support listed options.

    However, I recommend you contact HP support at the 1-800-474-6836 (to the United States and Canada).  Phone support can provide that more than an estimate on the repair or replacement of the printer with HP and you could compare this with the cost of a new printer.

    A new printer is under warranty and most likely to be an improvement on an older printer.
