Mini-UPS solution for Airport Express

Hello Airport community! This is my first post.
I'm wondering if anyone has had any luck with a battery backup (UPS) for Airport Express'. I have a larger UPS for my Time Capsule which is the main access point. I've hardwired this one into the network to broadcast the same network but extend the range. If the power goes off, since a number of devices are connected to the second, I'd like to have it on back up as well. However, it's installed very in a tidier manner in a smaller area – no room here for a big APC UPS.
I've been able to find 12 V battery backups, but nothing for the Airport since it's a 120/240 V input.
Anyone have any ideas of how this might be accomplished?
Cheers,
David

As a completely different kind of solution.. Although John's battery and car inverter idea is creative.. and will work..
Use an extreme or something else that is dc powered.. You can buy a cheap second hand extreme for $30-50 on ebay or whoever has your second hand market. It can even be a different brand.. tp-link, edimax etc.. most are 12v which is excellent.. then power it down the ethernet. So you don't even need a power point.
I'm wondering if anyone has had any luck with a battery backup (UPS) for Airport Express'. I have a larger UPS for my Time Capsule which is the main access point.
Plug the 12v power supply into your UPS.. with the TC.. and buy a set of injectors for ethernet..
They look like this.

Just a few dollars.. they passively use the extra pairs to carry power over the ethernet wiring.. you can also buy active sets but they are more expensive but keep the line at gigabit.

I have not hunted for cheapest but I have tried to keep price in mind.
There was a time when Apple used POE in the old domed Extreme.. and that was very handy.. the Express should have always had it.. it is a natural to power over ethernet rather than require power outlet next to it.

Mac Mini Server setup with airport express

I have had issues trying to setting up mac mini server on my network. I wonder if my current hardware is the problem? At present I have a Thomson Router plugged into an airport express which broadcasts wifi for my house. I have been connecting to my wifi with my mac mini server. Despite running server assistant and setting up a DNS server in Mac Mini server no clients are able to connect to the DNS server (i.e. dig command works on server but not on clients). I found reference somewhere on the internet to the fact that the mac mini server must be plugged into the router via ethernet for it to be setup properly.
Could this be the cause of my problems? Is it true?

Just to clarify this is an airport express and not airport extreme therefore I am reliant on a wireless connection between my mac mini server and the airport express.
The model of the Airport device here is largely irrelevant.
Currently my Thomson router serves out an address of 192.168.1.67 to airport express router.
Do you have any control over the gateway router?
The airport express is configured to share out a single IP address
Double NAT (which is what you have here) will cause you problems. Get rid of one layer of NAT.
The airport express gives out addresses in range of 10.0.1.2-10.0.1.202 with 10.0.1.1 being the address for the airport express and 10.0,1.201 being assigned via DHCP to the mac mini server (using its MAC address to reserve the address)
Within the private blocks, the IP addressing organization is your decision.
The DNS server is set on the airport express to 10.0.1.201 (i.e. my server).
OK. (I usually pick smaller numbers for more important boxes, because I tend to type addresses for those boxes more than the addresses of the boxes over in DHCP-land. But again, this is your call.)
I guess I wondered if something funky was going on with server assistant during the setup. A post I read somewhere (I've lost the link) was someone in an identical situation who had issues and said that apple had stated that he need to be directly connected to the router by ethernet cable to get things working. I wondered if this is the issue. An airport express does not have a spare ethernet port to plug into so I wonder if I need to buy a wireless router with built-in ports i.e. airport extreme (expense+) or something similar.
I'd probably switch the box to access point, but that presumes you can get (more) control over the gateway router.
I can access by Thomson router but I able unable to change the DNS servers that it provides (set by my ISP) from the GUI. I'm sure you could probably do it from the commandline but I think this is beyond me. I did wonder if that is what is causing problems
Talk with the ISP. You'd prefer to have the device switched to a bridge, if that's feasible. If not, then you're going to have to work within the confines of the particular model.

PIN-based guest access for airport express

how do I setup PIN-based guest access for airport express?
I have a 2010 iMac OS X 10.6.8 and an Airport Express of the same era.
Thanx in advanced...
Siegfried

Hello Bob,
Thank you for your time on this. I apologize for not giving you a more complete picture of what was going on.
I should have included that I had already performed the steps that you shared and had gotten to the place where I would enter the PIN.
The problem was that, after entering a PIN that I had come up with, the "continue" button never became active. I called Apple Care and ended up talking to 3 different people before I found someone that knew the answer. The answer is that the guest computer (client) MUST be present inorder for me to complete the setup. So, problem is now solved. Thanx...
Siegfried

Is there any antenna for airport express?

I think i´m having problemas with the signal of my airport express and all the readings i made always refer antennas for airport extreme base station.
My question is, if there is any antenna for airport express that don´t needs an extreme base station.
Thanks
Ricardo
Pentium IV Windows XP Pro

Two quick things to check using AirPort Utility on both devices:
On your "main" base station
Open AirPort Utility - click Manual Setup
Click the Wireless tab/label located just below the row of icons
There must be a check mark next to "Allow this network to be extended"
Click Update to save your changes.
If you don't see this option, you likely have an older AirPort Extreme that does not support the "extend" feature. Please clarify on the version that you have
On your AirPort Express
Open AirPort Utility - click Manual Setup
Click the Wireless tab
Wireless Mode = Extend a wireless network
Wireless Name = Same name as your main network
Check mark next to "Allow wireless clients"
Wireless Security = Same setting as your main router
Wireless Password = Same password as your main network
Confirm Password
Click Update to save settings
If you do not see the "Extend a wireless network setting", you may have an older AirPort Express, or if you are sure that you have a newer 802.11n model, try holding down the option key while you click on the selection box to see if the "Extend" setting will appear.
Assuming no major obstructions between the main router and area that needs more wireless coverage, a good starting location for the Express would be a point that is approximately half the distance between the main router and the area that needs more coverage.
As I said, this feature works very well if major obstructions do not come into play.

How to find MAC address for WAN port for Airport Express 2nd Gen.

The New Airport Express has a LAN and a WAN ethernet ports. How can I find the MAC address for the WAN ethernet port as my Service Provider needs it for provisioning....I can fid MAC address for Ethernet and for two wireless 2.4 & 5GHz but not for WAN ethernet port using Airport Utility 6.1

Many thanks for the swift response. However, there is no WAN MAC address on the box or on the device anywhere. I even used magnifying glass to find one .
The airport utility shows only three mac addresses. One for 2.4GHz, one for 5GHz and one fo the ethernet (LAN port) whereas there is another ethernet port in the device mentioned as WAN port and I am still not able to find the MAC address for the WAN ehternet port for Airport Express (2nd Generation).
Will appreciate a response to make th device work wiht my service provider as providing them the WAN mac address is a must. Had there been an option for cloning mac address, the issue would have not been there.
Many thanks again - in advance.

ITunes 11 hangs up on iMac looking for airport express.

Any help is appreciated, struggling with Apple issues. I have 3 airport express units set up to act as individual zones for a multi-channel amplifier in my home. The main iTunes library is housed both on my iMac running OSX Snow Leopard as well as an external network hard drive. With the latest upgrade to iTunes 11 i have noticed while directly using iTunes and through my iPad using Remote that iTunes gets lost and stops working. The screen will show that the program is trying to locate the airport express zone and you cannot close the dialogue box or close iTunes. When i view the airport utility it shows all of the airport express units functioning properly. The only way out is to manually shut down the computer and re-start. Is this an iTunes issue or possible setup issue with the airport express units. The 3 devices are in close proximity to each other feeding the amp but, functioned properly prior to the new iTunes release. Not as familiar with Apple networking and appreciate any ideas to remedy. Nothing worse than rocking out to a great tune only to have it stop mid-song with the only solution to shut down the iMac.

The same goes for iTunes 11.2.1 on 10.9.3. And it's not the first time, either. In fact, I've lost count of the number of times a software update has broken Airplay. It's immensely frustrating. If past experience is anything to go by, they'll fix it in a few months' time but until then there's nothing we can do about it. Unless someone can tell me I'm wrong?

Multiple speakers for airport express

I'm trying to connect multiple speakers from my Itunes but I can't get it to work. I can get one or the other to work but I can't get both to work at the same time. I updated the software for A-express, still doesn't seem to work. Anyone else have this problem? Is there a solution?
thanks

Hi
I have been having the same problem since I purchased an Airport Express. You can select one or the other speakers, but an error message comes up if you try and select both.
It is rather more annoying given that I have 'remote' on my iPod Touch which completely locks up if you try and change the speakers.
I have had no luck getting Apple to understand the issue - despite several emails and phone conversations with support. Ultimately I consider it to be a software development issue.
Hopefully they are reading these posts!!

How do I keep my 2006 mac mini from "disconnecting" with airport express?

how do I connect my airport express to my mac mini and keep it connected?

Thanks! I upgraded the firmware on my Medialink Wireless N router, and connected it to my Airport Express via an ethernet cable. The Epson Artisan 835 printer is connected via USB to my Airport Express. Everything seems more stable since updating the firmware (from late 2010 to late 2011 version). I did this at 8:30pm and at 10:25pm am still able to print. I'll give you an update in the morning. Thanks for your help!

How do I know if my mac is compatable for airport express?

Stupid question I know but I have a minimac osx 10.3.9 when checking
under system profile this is the info I get: hardware: airport card: no information found.
I take it this means I cannot use airport express

Not sure about your question... The AirPort Express (AX) is a 802.11b/g wireless router.
...I have a minimac osx 10.3.9 when checking
under system profile this is the info I get: hardware: airport card: no information found.
I take it this means I cannot use airport express
That indicates that your Mac mini does not have a wireless card installed. Therefore you would not be able to make a wireless link to an AirPort Express (AX).
However... you could connect your Mac mini via Ethernet to a LAN port on a wireless router. Then configure an AX to join the wireless network as a wireless client. The Mac mini would then be able to stream music through the wireless router to the AX.

Printer recommendations for airport express

Hi all,
I posted a question regarding printer compatibility with airport express. I already bought two and both were glitchy. I am trialing a canon s520 with the view of buying the new model. I put up a post, and got a lot of answers. Unfortunately some say one thing and some say the other. I have noticed that when there is a serious issue with apple equipment, the answers become garbled like this. BTW the s520 hangs a lot. So canon is out. Best advice i got from a couple of posts was dont both with wireless printing via AE. Buy a printer with its own wireless set up.
Dont get me wrong, i love the discussion groups and the advice i get.
My question is this..
Does airport express really work PROPERLY for wireless printing. I thought is was great feature. Would love to continue using it. But since tiger, i seem to have had a lot of time wasting problems. Is apple losing it... And surely they must have a list of recommended printers to work with AE.

My question is this..
Does airport express really work PROPERLY for
wireless printing.
Yes I have managed to get various printers working PROPERLY with my Airport base stations.
And surely they must have a list
of recommended printers to work with AE.
There is the unofficial list.
The iFelix unofficial Airport Extreme and Airport Express Printer Compatibility List
http://www.ifelix.co.uk/tech/1013.html
This is an unofficial list of USB printers which are are compatible with the AirPort Extreme Base Station and Airport Express. Printers in bold have been added to the original list that Apple provided. Printers in dark red are in fact the only printers I have personally tested.
Please also note that due to changes in the firmware of both the Airport Extreme base station and the introduction of the Airport Express some printers which are in this list may no longer in fact be compatible.

Mac mini unable to locate airport express

Since getting new modem from Comcast Xfinity, Mac mini (Airport Utility) has been unable to locate Airport Extreme and Airport Express. Can anyone help?

OK, you have a choice you cannot use the Extreme as an extender, you can use it as your primary router or use the Comcast device as your primary router. If you choose to use the Extreme as your primary router then you need to call Comcast and ask them how to turn off the router abillities on their device. If you want to use the Comcast's router then you need to remove the Extreme from the equation and use the Express as an extender.

Can't set up security for Airport Express?

Hello, we are tearing our hair out trying to set up Airport Express.
We have installed and are using the Airport Utility. We plug in the AX and it is a slow flash amber. It s being registered by our mac so we join the default "Apple Network XXX" then open Airport Utility. Checking the base station status it lists 4 items that need attention, we can work thru all of them but keep getting stuck on "Wireless Security".
We get to the point where it says select "WPA2" or "no security", we select WPA2, hit continue it then gives us the message "wireless network name is required to continue" but there is no where to select a name or enter one, the base station is also selected in the LH panel? We can't get past this point.
We have also previously in other screens already put in a password for the base station and again for the airport express - is this a 3rd password?
Any help would be greatly appreciated.
Many Thanks! - Danielle

Danielle, welcome to the discussion area!
Try the following: Open AirPort Utility and click Manual Setup
Click the Base Station tab just below the row of icons to assign a name to your device, a device password (write that down) and adjust time settings as needed.
Click the Wireless tab and work your way down the page
Wireless Mode = Create a wireless network
wireless Network Name = Your choice
Check mark next to "Allow to be extended"
Radio Mode = 802.11n (802.11b/g compatible) is a good choice
Radio Channel = Automatic
Wireless Security = WPA2 Personal or WPA/WPA2 Personal
Wireless Password = backspace to clear out anything here and re-enter your desired password
Confirm Password = Same as above
Click Update to save your settings. See if that will help.

Need Help With Download For Airport Express

Ok, computer dummy here needing help with airport express. We were given airport express last night from a friend who recently purchased a newer gadget. He told us we would need to come here to download the operating system. I see lots of links to updates but no links for someone like me who has never had anything like this on my computer before. Does anyone know what link I would need to use? We have a pc with windows XP. Thanks so much for your help!

Hello jesschambers. Welcome to the Apple Discussions!
The AirPort Express Base Station (AX) doesn't have an "operating system" per se, but it does have built-in firmware which pretty much is the same thing. In addition, in order to administer the AX, you will need the AirPort Admin Utility for your Windows PC.
Here are the links for the latest versions of both:
o AirPort Express Firmware Update 6.3 for Windows
o AirPort 4.2 for Windows

Best wifi hardware for airport express

Hi
m looking for ideas for buying the best wifi hardware (accespoint) good for running the airport express.
I have an asus wifi-onboard card right now, but the card looses connection after aprox one hour - then I have to reassosiate with the airport express.
thanks

With regards to wireless interface adapters for PCs - any make/model should work just fine. If you want to try an alternative, stick with a product from one of the big names in the business of making these adapters like Linksys, Netgear, D-Link, or Intel.
That being said - there are common causes for "dropped connections" other than a "bad card". Interference from neighboring wireless networks and 2.4 GHz portable phones, for example, will also cause problems exactly like you describe. Before replacing the card, you might experiment with changing the wireless channel of the Airport Express (try 1 or 11) - a setting found under the Airport tab of the Airport Admin Utility.
