Trying to connect two computers to Airport express

Hi, i have two mac minis which i am trying to connect to the internet via airport express to a modem. No problems with one of them, very reliable but i can't get the other to connect. It staes there is no ip address . This is when using the "configure ipv4 using dhcp" When i tried manually and copied the same address it appeared to work except it said that another computer was using that i.p address. (which is the one that always is working) Question is, cause i am a newbie, what ip address should i use? Thanks.....

How is your Express configured? In AirPort Utility select the Express and click "Manual Setup". In the Internet panel, Internet Connection tab, "Connection Sharing" should probably be set to "Share a public IP address". As you mention, each of your Macs should be set with "Configure IPv4" to "Using DHCP".
If all those settings look good, you might try resetting your connection settings on the problematic Mac using the steps listed in this message:

They're not guaranteed to solve the problem, but they'll only take a minute or so to try.

While trying to connect / configurate a second airport express it has suddenly can´t be found by the computer/ airport express manager. Any suggestions to how I can "find" it again?

I have tried to connect a second airport express to my Mac. But the configuration was interrupted and now I can´t find the second airport on the Airport Express manager display. Although I find it on network/ system settings. I appriciate any suggestions!

Hold in the reset button on the AirPort Express for 7-8 seconds, then release and allow 40-45 seconds for a restart to a slow, blinking amber light. Then reconfigure the device again.
You can also temporarily connect an Ethernet cable from your computer to the Express to establish a direct connection for the setup, rather than using wireless. Once you have the Express configured, you can disconnect the Ethernet cable.

Settings in OsX to hook up two computers trough Airport Express

I want to get access to a external harddrive with Mp3s that is connected to my iMac mini through my G5 that are both connected to my Airport netwoork at home. What would be the best way to set it up? What should the settings be on the computers?

You will need to use Sharepoints in order to share the hard drive.

You're welcome.
Voicemail is left at your carrier's server. That will continue to work unless you report your iPhone as lost or stolen with your carrier.
You may never find it again and you can't if the iPhone remains offline or out of service which means the iPhone is powered off or doesn't have cellular reception.

Connecting computers via Airport Express

I have a problem that I've been trying to solve, but so far nothing has worked.
I have three Macs, 2 G4 PowerBooks and an iMac (Core 2 Duo) which are all connected via an Airport Express. All of the computers can access the net and my printer just fine. The iMac can connect to both of the G4s, and one of the G4s can connect to both the iMac and the other G4. The problem is that one of the G4s can only connect to the other G4, not the iMac. It's as though the iMac does not exist for it's purposes. Yet I can connect to that G4 from the iMac, just not the other way around.
Any clues as to a fix for this would be greatly appreciated.

That is what you want to select.
You jumped into the middle of this thread. What
problem do you have?
More to the point - what is YOUR problem...I think your response was a little rude...
One who has common sense can see what issue I am having simply by looking at the subject of the original post - and reading my entire post.
For your benefit, the subject is: Problems Connecting Two Computers to Cable Modem via AirPort Express.
If you read my post again, you will see that after following the advice given by Rj, I am still having problems. I will not re-post my question. Simply restating things in this post has been a waste of time.

Can't connect to an extended Airport Express?

My network is set up in the following way (see photo) 1 Time Capsule + 2 Airport Express to extend the network.
No computers or devices can connect to the Airport Express named "AE02"? They all ONLY connect to the middle Airport Express called "AE01" even though they are like 20 cm from AE02??
What am I doing wrong? Anyone else has this problem?
Thanks

Thanks, Huge bummer... How come the Airport Expresses connect that way if not allowed?!
I found the answer just like 'Tesserax' pointed out.

Cannot connect two computers to the same game server HELP!

I have a Linksys WRT54G Router. I have two computers and I want to be able to use them on the same gaming server. Unfortunately, the game only have one port, so I can only port forward one of my computers. How can I configure my router to have two external IP addresses to the server so it won't kick one of my computers out. Thanks!

Hi,
I am in a gaming community and many members have a Linksys at home (but I don't know which kind exactly). Many of us try to connect two computers to the same server (many have a family). It seems it is a common problem that no one can connect two computers to the same game server.
I have a BEFSR41 V3 Firmware version 1.04.8
I use fixed IP address and no connectivity problem on Internet.
I have win XP SP2 on both computer.
I am using a DSL modem
I can connect the two computers to two different game servers at same time, but not the same server. Default port for this game is the same for all servers I use. I tried with both port forwarding enabled (in that case one PCs can connect the other not) or not (in the second case, whenever the second PC connects, the first one lose his connection to the server, no mater the order I try to connect my PCs).
Now the weird thing is that one member in my community just decided to throw away his Linksys router and he bought another brand (which I won't name to remains politically correct). Now, without changing anything in his PCs or his connection type, he can now play with two PC on the same server.
I am seriously thinking doing the same move. Since more and more game are now using Internet (and servers that controls piracy, $$) and family want to play together, not being able to connect two PCs on the same game server makes Linksys in bad situation from marketing point of view.
For example, in my gaming communtity, we now all know that Linksys can't handle two PC on same server, but other brand can...
Thank you in advance for your help.

My i-Pad2 won't charge after I downloaded some new stuff from i-Tunes. A note appears on the screen "Charging is not supported with this accessory". I have tried charging through two computers and with the wall socket plug (with another cable). I have

My i-Pad won't charge after I downloaded some stuff from i-Tunes. I have tried charging through two computers and using the wall socket,, with different cables. I have turned the i-Pad off & on a couple of times but it still won't charge. Any ideas will be gratefully received.

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Can I connect two computers to one device?

Can I connect two computers to one device? I am trying to have them control different aspects of the experiment that I'm running.

That depends upon the device. If it's GPIB, you could
use the E-NET card to convert it to LAN. That would
allow control by many computers. The only problem with
that might be sychronization. That is, Computer 1 does
its setup. Then Computer 2 does a reset. Compuer 1's
setup is now gone.
As another poster suggested, you could always network
between the two computers.

Can I extend my network by connecting one of my airport express devices to my airport extreme via an ethernet cable? I have CAT5 cable throughout my house but have a wireless network w/ 3 airport expresses

Can I extend my wireless network by connecting one of my airport express devices to my airport extreme via an ethernet cable? I have a wireless network with 3 airport expresses and 1 airport extreme functioning as the base station. I have CAT5 throughout my house.

Welcome to the discussions, mib88!
Can I extend the network a second time with another Airport Express...
The short answer would be no. If you want more details, please continue to the next paragraph.
Apple's "extend a wireless network" works just like the hub and spokes of a wheel. Your main hub is either the Time Capsule or the AirPort Extreme and the AirPort Express is at the end of a spoke. You can add more devices at the ends of other spokes, but these devices will communicate directly to the hub, not to another device at the end of a spoke.
Apple does offer an option which is is known as a "static WDS", which can consist of a "main", "relay" and "remote" device. The problem here is that this type of setup has two huge drawbacks:
1) All of your faster "n" devices will drop down to much slower "g" speeds
2) The bandwidth or speed capability on the network will drop down to only 25% of the original bandwidth with a "main", "relay" and "remote" on the network.
Don't think you want this on your network. Your best option is to connect the new AirPort Express to the "hub" using an ethernet connection. If you can't run the ethernet cable, take a look at a pair of ethernet powerline adapters to accomplish the same task by sending the ethernet signal over the AC powerline in your home.

Connecting to Comcast using airport express

My wife bumped the Airport express router that connects to our comcast modem. I unplugged both, reset the comcast modem, waited 3-4 minutes, then plugged the airport express router back in the socket. Went downstairs, couldnt connect to the internet according to the airport express utility application. Green light on airport express, orange light on the "Internet" in the utility. Called Comcast, total waste of time after 1.5 hrs of "tech support" was told to call Apple . Computer is 4 years old, has been working fine up to this point. Apple wants me to pay $49 for support. nothing guaranteed.
Any suggestions? I've tried turning off IMAC, running upstairs, unplug airport express, unplug modem, push reset on modem, wait 4 minutes for modem to fire back up, plug airport express back in, run downstairs, turn on IMAC, run airport express utility and same result, green for airport express router, orange for internet.
Opened up Safari, tried network diagnostics troubleshooting, it eventually asks me if we are DHC? or PPPoE. I choose PPPoE and enter comcast for service provider, enter username and password (as verified by Comcast) during my 1.5 hour session. trys to connect. goes back to same screen of do we have DHCP or PPPoE.
Frustrating!
Neighbor told me to plug IMAC directly into Modem and see what happens using an Ethernet hard connection. Will try tonight.
Any assistance is appreciated.

Bob,
I plugged the Ethernet directly into my Imac, clicked on DHCP, and I was connected. Plugged my airport express back in, unplugged cord from computer back to airport express, waited for green light on airport, tried to connect to my network, unable to get to the Internet. Wifi was on, just not able to connect to the internet.
So, I unplugged again, plugged ethernet cord into computer, back on the internet.
Puzzled. Airport seems to be working fine, amber light when first plugged in, green light after a few minutes.
Tried plugging in airport to comcast modem, reset modem, waited 5 minutes, tried to connect to internet, not able to do so.
Airport utility says airport express is fine.
needless to say, Im at a high level of frustration. Never ever had a problem this bad.
wondered if I unplugged airport express for 24 hours, then tried again, hoping it would clear out any memory on board and start the whole process of creating a new network over again.
Suggestions?
Thanks by the way.
George

Can I set up to connect 2 or 3 airport expresses to have a stronger wifi signal for a larger area?

Theoretically yes. It will really depend on your situation. Please review the following Apple Support article to understand what is possible with the AirPort base stations and post back with any questions or help in setting up your extended network.
