I am unable to join my existing wireless network with new AirPort Express

I am unable to join my existing wireless network with new AirPort Express.
I am using a DLink DI-524 Router, Windows 7 (64), and the AirPort Express.
AirPort Utility will not recognize the AEX wirelessly, it will only recognize it when it is connected by Ethernet. I can then configure the AEX and verify that the settings stick once disconnected and then reconnected. However, even after that, it will not recognize the AEX once disconnected from the Ethernet cable.
I followed the suggestions of several other threads on these forums. But I am unable to get the AEX to work.
Any suggestions? Thanks in advance.

Welcome to the discussion area!
It's almost always a security setting that causes problems when the Airport Express (AX) tries to join a third party wireless network. The AX usually does not "join" correctly and that's why you can't see it on your wireless network using AirPort Utility.
Using an ethernet cable is still the more reliable way to configure and adjust the AX, but if you are want to try to configure it using wireless, you must return the AX back to factory defaults as follows:
Power down the AX
Hold in the reset button +and keep holding it in+ as you plug the AX back in to power
Release the reset button after 10 seconds
When it is set to factory defaults, the AX broadcasts a wireless signal with a network name like "apple network xxxxxx" where the "x's" are either letters or numbers. You must look for this network by clicking on the fan shaped Airport icon at the top of the screen. If you don't see this network, then click Join Other Network to search that way. Unless you connect to this network, you will not be able to configure the AX using wireless.
Do you know the exact security type that your D-Link router is using? That is the key element in the process.
Open AirPort utility, click Manual Setup
Click the Base Station tab to establish a name for the AX, device password and adjust time zone settings
Click the Wireless tab
Wireless Mode....Join a wireless network
Wireless Network Name...must exactly match your D-Link wireless network name
Enable ethernet clients if you want the port to be active (your D-Link must be compatible with ProxySTA for this to work)
Wireless Security...exact setting of the D-Link network. WEP security causes a lot of issues. Try to use WPA/WPA2 Personal, which is far more secure.
Wireless Password...must match the D-Link network
Click the Music icon to enable AirTunes
Click Update to save settings
Any luck?

The Game Center is "unable to load data due to network connectivity issues or errors".

The Game Center is "unable to load data due to network connectivity issues or errors".
My internet is fine: all other apps that do not rely on the Game Center work, as does my browser and other online functions; additionally, a friend's iPhone connects to his Game Center perfectly while he is sitting next to me.
Closing the Game Center app and then reopening it is ineffective. Opening the options for the Game Center in the settings, logging out of my Apple ID, then logging back in, and then reopening the Game Center is ineffective. Opening the options for the Game Center in the settings, logging out of my Apple ID, then reopening the Game Center app and logging back in from there is ineffective.
This issue has gone on for more than a month, and so the phone has gone through all variations of "turn it off then back on again, refresh the system, etc etc" that are the basic first suggestions for trouble shooting.
One game app, which required a Game Center profile to launch, stopped working entirely, and would return a message saying something like "connect to the Game Center". I eventually deleted it to free up space. Other games which can be linked to the Game Center to connect with friends simply fail to link, returning "Game Center unavailable". This is the aspect that is currently bothering me the most: I cannot play games with friends unless the app can also link to Facebook and connect to friends from there.
When I open the Game Center, I see the following screen. The bubbles float gently, and it seems as if I had the ability to update my "status". However doing so results in a message that has vanished once the app is reopened.
Upon tapping Games, either the bubble from the main screen or the option on the ribbon at the bottom, the following screen appears. Clicking on Challenges shows a message that achievements must be viewed to issue a challenge. Clicking achievements results in a message that games must be connected (and from my friend's phone I know I have several apps that should appear).
Upon tapping friends, it does show me a list of suggested friends pulled from Facebook, but attempting to send a friend request results in the following screen. After accepting the error box, the "send" button for the request is grayed out and unavailable regardless of adding or deleting friends and/or an accompanying message.
In short, the Game Center is completely unresponsive for no discernible reason, and this problem began with no warning and is now long term. Though my iPhone is older (a 4s), my friend's is even older (a regular 4) and works fine.

I am having the very same problem on my iPad running ios 7. All is fine on my iPhone it opens no problem - this is running on ios 8. I wish they would fix it.

Macbooks unable to get DHCP from Wireless Network

Our PC Laptops can connect to our Cisco Wireless Network (using wireless controllers and lightweight AP's) without issue.
However Macbooks and several other devices are able to connect and get an IP address via DHCP. If I manually put an IP in the Macbooks wireless configuration it can connect without issue, if I don't do this the Macbooks timeout and say using self assigned ip address and will not get on the network.
Any thoughts on what is causing this and how to fix?
Jim

Make sure you don't have client load balancing enabled on the WLAN advanced tab.

Unable to Find Address Without Wireless Network Co...

Nokia Maps v.2 on my phone attempts to search for an address on-line every time I enter a destination point. 99% of time it works great but only when I have wireless network coverage (I am using AT&T Wireless). However, we just went to Maine, where ATT's wireless coverage stinks. In the area where we had no wireless coverage the phone was attempting to find the address on-line and after a minute or so would return a message "unable to find the address."
Since I had Maine maps downloaded on the phone, how do I get the phone to use the databased stored on the phone instead?

Yup, an IP of 169.254....is self-assigned when it cannot get one from the router. The WPS button does not reset the router.
Do this on the printer: Setup > Network > Wireless Setup WIzard. Follow the instructions.

Cannot Maintain Stable Screen Share Connection New MacBook Pro

I am having some difficulty maintaining a stable screen share connection. It just keeps disconnecting and reconnecting. It has nothing to do with my network as I have tested it from 5 machines and it's only this one.
Has anyone else experienced this with the new MacBook/ MacBook Pro's?
I have  MacBook Pro - 15" 2.53Ghz/4GB RAM/320GB @ 5400RPM
Thanks,
Dean

A little update. I have found what caused this.
When my MacBook Pro was trying to Screen Share to my iMac it would ONLY drop out when connected to this particular machine. The iMac is a 24" Aluminum 2.4Ghz it is running @ 1920 x 1200 with a 23" Apple Cinema Display connected to it @ 1920 x1200.
When I mirror the display the screen-share connection stays stable. Only when I change it to Extended does this issue occur. I am wondering if any other users have experienced this? Possibly it could be a bug in the OS as it doesn't like multiple displays during screen share.

Unable to reconnect to wireless network after closing lid on macbook pro

After installing recent software updates, I am unable to reconnect to my wireless network when I close the lid on my macbook. It says that it is "connected", but I can't access any website, check e-mail or ping any external server.
I've never had a problem before, but now that I've installed software updates in the past few weeks I noticed the problem.
Anyone have any ideas?
MacBook Pro (Intel) Mac OS X (10.4.9)

which ultimately means apple didn't do enough testing before releasing the last patch
This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
However, I do agree with you in that Apple should put more work into their Airport software.

The password for wireless network was changed. Airport keeps trying to sign in automatically with old password and won't let me put in new password. Any ideas?

You really should change both the wireless network name and password to avoid potential conflicts with the old and new settings.
Suggest you give that a try.

Ora-30926 : unable to get a stable set of rows in source table

Dear All
When I try to load my cube I get the error "ora-30926 : unable to get a stable set of rows in source table".
Any idea? Googling for this error did not return any solutions.
My env:
source: Oracle 10g (10.2.x)
Target: Oracle 11g (11.1.0.7)
I am using warehouse builder 11.1.0.7 on Linux
thank you

Carsten / neashton
Thanks for your help. Duplicate rows were the issue.
I finally debugged the problem to my time dimension.
The OWB wizard generated time dimension contains only date, but no time.
Unfortunately, for me to uniquely identify my data, I need to include time also (detailed in how do I include 'Time' in a time dimension? .
Since Carsten was the first one to answer this, I am awarding the points to him.
thanks a lot both of you

Idea Tab a2109a wont connect to wifi without ssid broadcast

I have Idea Tab a2109a that connects to my wifi just fine, until i shut off the ssid broadcast from the router. At that point it stops connecting and says out of range. Laptops and a KindleFire have no problems maintaining a connection without the broadcast.
Running Android version 4.1.1
Kernel version 3.1.10
Model number IdeaTab A2109A
How do i maintain a connection on this tablet WITHOUT the ssid broadcast?

I tried your suggestions as much as I could at the corner coffee shop, but they didn't help.
I didn't follow them exactly because I misinterpreted turn WiFi on as turn it off. But when I sort of made up for that, I could not access it.
I realized my mistake when I came back home, went back to the coffee shop and tried again. Unfortunately, the signal was now one bar, and so I'm not sure that I've proved anything.
As I came back home, I searched for my network. I found it almost at my front door and with a strong signal. I walked around the outside and the access would come and go. Every time I could get access again it was always strong, even as neighbors' networks varied in signal strength. So, I couldn't double check if I would have gotten through with a weak signal.
So, I can access the web on my iPod touch on a closed network but not an open network.
I can access it at home with an ActionTec GT701-WG DSL modem. I can access it with a coffee shop provided access to ClearWire, a wireless Internet provider. This latter requires registration at hotspots.
I have software version 2.0.2 (5C1).

I am unable to get my iPhone 4s to connect with my JBL Flip speaker via bluetooth anymore. I have been using it for 2 months and now it just wont find device. Any ideas?

Where exactly did you buy this phone?
Have you tried contacting your phone carrier to activate the phone?
Do you have a sim card?
