When connected directly to another non-AirPort router via Ethernet the only way to "extend" that other router's wireless network is via a roaming network configuration. Since the ISP's router has changed, I would start all over again with establishing this type of network.
Do you want this wireless network to also have Internet access? If so, the AirPort Express MUST be connected back to the other router via an Ethernet connection. If not, then you can just use the Express in its default configuration which broadcasts an unsecured wireless network with a network name of something like: Apple Network NNNNNN ... but it will not have Internet access.
Yes, I want to create my own wireless network with full Internet access, and I am currently connecting my Airport Expresss to the other router with an Ethernet cable. The current situation is that if I want to create a new network, the Internet disconnected. What have I done wrong with the configuration?
What have I done wrong with the configuration?
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Express icon
Look for the Status of the connection to see if there are any amber dots that you see
Report back with any errors that are listed next to an amber dot
Here is the situation on my Airport Express.
If I choose to extend the existing wireless network, the Airport Utility shows like this:
If I set up a wireless network of my own, what I get in the Airport Utility is this:
See my problems here? The Airport Express does not show anything in amble, but the Internet complains that there is no connection.
This problem did not occur before the broadband was renewed and the rounter was replaced.
Thanks for posting the screenshots. I cannot duplicate this when I try to create a new network, but I am using an Apple router, so I cannot test with another brand of router.
Please try to reconfigure the Express to "extend a wireless network" If you can do that, we may be able to go back in using AirPort Utility and change the name of the wireless network. Then you will have your own network.
Post back when you have the Express set up to "extend".
Another reason I don't want to extend the existing network is that, sometimes the Airport Express is lost in the Airport Utility. A warning symble appears next to the Airport Express icon. Clicking the Airport Express icon displays a message saying that the Airport Express cannot be found, and there is a button 'Forget' on the bottom of the message. When this button is clicked, the Airport Express icon is gone.
I bought an Airport Express, connected it to the shared router with an ethernet cable and set up a wireless network of my own in my room.
Sorry, but the screenshots that you posted indicate that the Express is connecting using wireless only.....not Ethernet. I understood from your information just above that you have an Ethernet connection established between the router and the AirPort Express.
If Ethernet was active, there would be a solid line between the connection and Express.....not a dotted line.
Did you see my first four screenshots? When I chose to create my own network, the Airport Express was connected to the rounter using the Ethernet cable. When I switched to extend the existing network, the Airport Express authmatically switched to wireless connection, even if the Ethernet net cable still connects it to the router.
You cannot have a wireless connection while an Ethernet cable is connected at the same time. This creates "looping" Things will never work this way.
When I said "extend", I meant the original setup of the device. Reset the Express back to factory defaults, connect the Express using Ethernet and accept the option to "extend" the network.
If this works, you will be connected using Ethernet and you will have the same wireless network name as the main network.
Then, you can go back in using AirPort Utility and manually edit the wireless network name to anything that you want. Then you have your own network.
I just tried this with my AirPort Express connecting to a Netgear router at my neighbor's.
Start from a Factory Default Reset
Connect using Ethernet
Start AirPort Setup and let it analyze the network and announce that the Express will be setup to "extend"
Follow the steps
Now the Express will be broadcasting a signal with the same wireless network name.
Now it is easy to to change the name of the wireless network and password using AirPort Utility...so you have a new network with a new password.
It works fine. I am using it right now to type this.
