Airport express in bridge mode and wrong IP

Hi all,
my airport express is driving me nuts!! I'm trying to set it up in bridge mode, just to share the printer and to use airplay, bridging the network of my ISP router, that works fine in wifi mode with all my devices (tested with: 2 MacBookPro, 3 iphone, 1 ipad).
The issue is that I configure the AE to join my network (using airport utility), it restarts and works just for few minutes and then it drops the IP, and it turns out to not be visible even for airport utility.
I've noticed that in the summary configuration page of airport utility the IP assigned to the AE is kind of 169.254.X.X that means that the AE is not reciving a valid IP from the router. But, if I press "manual setup" and load the internal configution, in the TCP/IP pannel there is a righ IP number.
But it stops working anyway :-(
I've already tried to configure it with a static IP num (in my IP range), but it did not work as well.
Last thing: my AE is the old one, 802.11g.
Any suggestion?
thanks in advance and happy new year ;-)

When the AirPort is setup to operate in Bridge Mode, all ports behave as if they were LAN <--> ports, so it would not make any difference which port is used. As a personal preference, and also to aid in troubleshooting, I use the WAN "O" port when configuring a network, if only to know at a glance which cable is which.
The settings on the AirPort are interactive, so when/if you change the Network Mode to "create a wireless network", that will throw the AirPort back into router mode, so always check to make sure that the AirPort is in Bridge Mode as the last step before you click update to save the settings.

How to set up Airport Express in Bridge mode for hotel use

Please provide step by step instructions on how to set up Airport Express in Bridge mode for hotel use. I do not have a computer with me, only an iPhone and AEX 802.11n.

+"Please provide step by step instructions on how to set up Airport Express in Bridge mode for hotel use. I do not have a computer with me, only an iPhone and AEX 802.11n."+
AirPort Utility is the application that must be used to setup and make any configuration changes to the AirPort Express. I'm not aware of an "App" for this.
If you could borrow a computer from someone there for 30 minutes or maybe use the computer in the lobby, you could download AirPort Utility and reconfigure your Express. To help with setup, use an ethernet cable from the computer to the Express to help AirPort Utility "see" the Express.

Airport Express in Bridge Mode.. No AirTunes, limited functionality

I can only get my internet connection working through my Airport Express (AE) in bridge mode (i.e. the AE connects using 'Ethernet' as opposed to PPoE or WDV).
My computer is then able to connect to the internet using PPPoE.
Interestingly, the amber light is flashing although the internet connection is working fine.
Also, I cannot use AirTunes, and Airport Admin Utility cannot see the Airport Express.
Now, if I go into System Preferences>Network and disable PPPoE and check DHCP instead, I can see the Airport Express in Airport Admin Utility, the light becomes solid green and AirTunes starts working... BUT... my internet connection stops working!
Alternatively, I can now go into Airport Admin Utility and configure the AE to connect using PPPoE. However, no matter what settings I input in System Preferences>Network, the internet connection does not work. However AirTunes does work, the light is green and I can find the Airport in Airport Admin Utility.
It wasn't always like this. Sometime in late November / early December my Airport Express suddenly stopped connecting to the internet. Since then I've been trying very hard to get it working again, with numerous resets etc but its just not happening!
Can anyone tell me what I'm doing wrong or what I should do?
Thanks in advance (from a recent Apple convert)

Thanks for the very quick and helpful reply.
However I've tried on numerous occasions to configure the AX to connect to my ISP using PPPoE but it's always "looking for a PPPoE host". In addition, my ISP tells me that when I try and connect through the AX they dont see any requests coming in.
Was there a firmware or similar upgrade sometime in late November or early December of this year? I'm asking because all was fine prior to this period, after which internet through the AX only works in bridge mode, with the amber light flashing and no AirTunes functionality. Perhaps if i roll back the driver/firmware then it will start working again?
Also, is it a limitation of the AX that you cannot use AirTunes or even Airport Admin Utility to configure the AX when the AX is in bridge mode and the computer is not using DHCP to communicate with the AX? That doesnt seem to make much sense to me.

[Porblem] Airport express in bridge mode

Hello all,
It's my first post
I've got a problem using my all new airport express 802.11n...I explain, I've got a airport extreme base station(Fast ethernet) in mode n (channel 36) and I would like to connect my xbox(not a 360) using wireless...
I bought the airport extreme(so also in 802.11n) and I setup it as "extend my network" enter the passphrase etc and finally connect through a regular RJ45 my xbox and my airport express
The result is that I can connect my private network using my xbox but with very slow speed...2 MByte/sec...
I expect better speeds using n mode...normally it's 130Mbit/sec ...I'm really far from this speed...but very close from a 802.11g ...maybe that's normal..
Maybe someone can explain my how to increase the speed...
I'm using 7.3.1 for both of my airports (express and extreme)
Also, someone know where to find the older firmware???
Thanks all in advance.
Ed

Hmmm... I would say that this should work. I've got a Dual-Band network, and my sons' 360 is connected to my AEBS-g network via an AX-g and a Gigabit ethernet switch. The 360, 2 ReplayTVs and a DIRECTV HR20 all run fine on the g network.
One thing I've done is to run my AEBS-n at 5 GHz, n only to minimize any interference between the two networks.
Now that Apple finally upgraded the AX to n, I'm seriously considering upgrading my AX-g's to n and I would expect that the 360 should work.

Airport Express in bridge mode: has a green light but..

But it's not showing up as a connection on my iPad, or any device for that matter.
I have a linksys e1000 as a wireless router, which is connected to a little black black via Ethernet.
I plugged in my airport express and set it up through my iPad as an addition to a current network(extend the range). I named it 'xxxxx extended' and set a password for it.
Then it says it's complete and the light is green. So all should be fine but it's not letting me connect, it's not even showing up as an option in the wifi settings.

First, an Airport can NOT "extend" the WiFi created by a non-Apple device. Period.
An Express can "extend" the WiFi created by another Airport. You need TWO Airport units, one to function as the main radio and the other to function as an extender. I used two Express units.
Configuration is simple if you start from a factory default condition. Connect the main Airport to AC power and finally to the Internet modem (or modem/router). Open Airport Utility on your Mac or other computer and accept all of the recommendations. After confirming that it works, insert your desired administrative and WiFi passwords.
Then connect the extender to AC power. As before, open Airport Express on your Mac or other computer and accept all of the recommendations. No need to add password info.
Do not expect the Airport to respond instantly to the configuration commands. BE PATIENT!

TC connected PPPoE, Ethernet TC to wired router wired router to two A express in bridge mode other Ethernet from TC to Mac mini

Network not connecting o internet randomly?
Could anybody help? Need some info about what's happening with my internet connection sometimes.
My setup:
Time Capsule connected to Internet via PPPoE, one TC Ethernet port wired to a Mac Mini. Other TC Ethernet port connected to a wired type router. From this wired router, two of its ports connected to two Airport Express in bridge mode so, extending same network name as TC.
Mac mini is connected to Internet via network cable and to the wireless network in order to print or use airplay in the rest of the house's floors.
Problem seems to be random. Sometimes we 'are unable to connect to internet wireless in either of the rooms.
I don't know if it has something to do with the problem but I think that, when Mac Mini is accessing internet (I suppose via wire), the wireless network is not able to connect to internet.
However if we try to connect via the wireless "guest" network from the TC (Airport Express guest networks disabled), we are able to connect.
Does any body has any idea why is this happening? Appreciate any help on this!

A couple of things to check......
PPPoE connections are tricky. What works well for one user may not work for another.
Leave the Service Name area completely blank on the main PPPoE setup page in AirPort Utility.
Experiment by trying the "Always On" and "Automatic" settings in AirPort Utility for the PPPoE setup of the AirPort Extreme to see if one setting might be more reliable than the other.
Other TC Ethernet port connected to a wired type router. From this wired router, two of its ports connected to two Airport Express in bridge mode so, extending same network name as TC.
Make sure that the wired router has been configured to operate in Bridge Mode, not in router mode, since you only want one device.....the AirPort Extreme.....providing DHCP and NAT routing services for the network.

THe Disk of the Time Capsule cannot be written by Time Machine when an Airport Express is bridged to it by Ethernet

Whenever I add an Airport Express in Bridging Mode to the existing WiFi network of the Time Capsule (both connecting to the same GigaBit Ethernet ADSL modem router, Time Machine (and Finder) cannot backup to the Time Capsule Disk.
(Why do I need to add another Airport Express to the same WiFi network? Because I want to use the AirPlay jack on the Airport Express to output audio signals.)
If I unplug the power of the Airport Express, everything back to normal.
What's the problem?

Hello Ivan H
Try using the setup process in the Connecting to an existing Wi-Fi network, exclusively for iTunes music section of the article below and set it up wirelessly as opposed to a wired connection between the two base stations.

Using an airport extreme in both bridged mode and guest network with DHCP

I currently use a third-generation airport extreme in bridge mode to connect my various Mac servers To the Internet. I'm using bridge mode on the AirPort Extreme because I have up to five static IP address (only using three now) I am currently not using the wireless network, and none of the servers are serving DHCP. I am looking at the Newer airport extreme with guest network Wi-Fi. My question is, does the new airport extreme base station support bridge- mode for any devices and host DHCP for the guest network connecting wirelessly to the base station?

The AirPort Extreme cannot be in Bridge Mode and support a Guest Network.
The AirPort must be configured to provide DHCP and NAT services if you want to enable the Guest Network function.
If you really do have a 3rd Gen AirPort Extreme, it will support the Guest Network feature if you connect the AirPort directly to a simple modem.....not a modem/router or gateway type of devices.......and configure the AirPort to provide DHCP and NAT services for the network.

AirPort Time Capsule. Read everything and tried everything. Can't get a guest network to work. Switched from bridge mode and still doesn't work. Anyone able to set up a guest network?

I had a bright house cable modem that also had built-in wi-fi.
Don't mean to be picky here, but if the "modem" had built in Wi-Fi, it was not a modem. It was a modem/router, also known as a gateway type of device.
A device like this combines the functions of a separate modem and separate router in one package. Turning off the wireless on a device like this does not make a it modem.....it is still a modem/router or gateway with the WiFi turned off.
I think that if I have them replace the current "complicated" modem with a "simple" one I should be able to get the guest network up and running.
That would be correct. Hopefully, they offer this type of option for their customers.

How do I put AirPort Extreme in bridging mode from iOS app?

I need to put my AirPort Extreme into bridging mode. I've searched here and the Net and can only find how to do it from a Mac. Can someone please tell me how to do it from the iOS AirPort Utility? This is a Windows and iOS device only network. I do not have any Macs and the Windows version of the utility so far only supports the Express.

Thanks for the response, although I was a bit crestfallen at first, since I had already got that far but could not change the Router Mode. Your response did let me know I was indeed on the right path so I started thinking about what else might need to be changed. I finally figured out that before selecting "Advanced" you need to:
Select Internet Connection
Change from PPPoE to DHCP in the top group of three buttons
Then continue as you described
At that point I could change the Router Mode to Off and I'm happily WiFi-ing with my spiff new Apple router. Ah well, that's what I get for not having any Macs

AirPort Express in Client mode

If you configure a current (summer 2012) simultaneous dual band AirPort Express in client mode:
1) are both the LAN and WAN ethernet ports available or only one of them, the LAN port presumeably?
2) If you unplug the ethernet cable momentarily to connect a different device, does the AX drop the wireless connection or is it maintained?

1) are both the LAN and WAN ethernet ports available or only one of them, the LAN port presumeably?
Both ports operate as LAN ports in this type of setup, since the Express will be configured in Bridge Mode automatically.
2) If you unplug the ethernet cable momentarily to connect a different device, does the AX drop the wireless connection or is it maintained?
Wireless will be maintained, but you may need to power off and restart the Express.
Better practice would be to power off the Express before you disconnect the cable(s), connect the cable(s) again, then power up the AirPort Express.

Trying to use Airport Express (2012) in Hotel and it is not working

Hey folks, the title pretty much says it all. I picked up a new AE last week, and wanted to use while I travel to share out my hotels wired connection to my computers, iPhone and iPad. I am pretty good with networking, so I can't seem to figure out how to get around the double NAT error that I am getting from the Airport utility. It appears that the hotels network is blocking me from connecting. If I use my back up travel router (Zuni Connect) everything works fine. It appears the AE is not getting along with the hotel. Any ideas on how to get around this?

I traveled for years with an AirPort Express and have had virtually no problems connecting to the hotel networks if an Ethernet port is provided in the room.
Up until a few years ago, configuring the Express in Bridge Mode worked just fine, as hotels would allow several devices to connect without problems.
Unfortunately, hotels have become a lot smarter as they look for ways to generate more revenue. Many hotels now will only allow one connection if the Express is configured in Bridge Mode, so I started using the Express in router mode about 3 years ago to get around this.
Security wise, this is actually a bettter arrangement as Tesserax notes, because other users at the hotel cannot "see" your devices.
The Double NAT "error" can be ignored with an option in AirPort Utility if you wish, and the Express will display a nice, green light.
I have no trouble connecting 3-4 devices this way and the hotel only "sees" one device, so they only charge for one connection.
When the hotel only has wireless, that is when I bring out the second Express that I travel with, so I can use one Express to "join" the hotel network and provide an Ethernet signal to the second Express, which is configured as a router to allow multiple devices to connect. The hotel only "sees" one connection this way.

Question about TC setup, bridge mode and security...

Hello All
I need some help...
Have bought a 1 Tb TC to use with my existing ethernet/wireless all-Mac home network but have some specific queries.
The system is set-up as follows:
Cable modem > connected by ethernet cable to > 8-way Ethernet switch
Connected via ethernet cable to the 8-way switch are: one MacBook (in another part of the house) and the TC (via its WAN socket).
Elsewhere in the house, and _all connected wirelessly_ are:
iMac G5
Powerbook G4
hi-fi (connected via an Airport Express)
Airport Extreme basestation to which a HP Laserjet is connected via ethernet.
Question:
Before buying the TC, I used a spare Airport Express basestation in its place to act as the 'main' basestation and the IP addresses of each device on the network were 10.0.0.1, 2, 3, etc. I had the impression that my home network was not "seen" by the outside world as a consequence of this.
Now, the TC seems only to work when in 'bridge' mode and it seems that the IP addresses are 196.xxx.x.100, 101, 102 etc. Does this mean that these devices are now visible to the outside world. Have I compromised my network security? I am worried that the outside world may have access to the contents of my TC, although my TC is password protected and the wireless network is 'closed'. What else should I be doing?
Finally, should I have set up the network so that the cable modem feeds to TC directly, with the 8-way ethernet switch coming off one of the ethernet sockets on the TC?
In all honestly, the instructions in the manual and the help guide are less than clear.
Can anyone help?
Thanks
Daniel

Section 4, here are my thoughts.
1. Since you are currently seeing individual IP addresses like 196.xxx.xxx.100, etc., it sounds like your modem is also acting as a router. This also seems to be the case since the Time Capsule is only working in bridged mode (it wouldn't work in Share a Public IP address if another device is assigning private DHCP addresses). Now, you could still allow the Time Capsule to act as a DHCP server on your private network by enabling Connection Sharing as Distribute a range of IP addresses. This will create a private network within your private network where all the devices that are connected to your Time Capsule can see each other. If you leave it in bridged mode then you allow your cable modem to assign DHCP addresses and all devices that are connected to the Time Capsule or to your ethernet switch are on the same network.
2. Assuming your cable modem is acting as a router you shouldn't have to worry about security, although you will have to access your modem's settings to make sure port forwarding isn't enabled and that the firewall is turned on (although I'm sure it is). I personally would plug the ethernet switch into the LAN port of the Time Capsule and allow the WAN port of the Time Capsule to be plugged into the cable modem. I also would just leave the Time Capsule in bridged mode as well, that's what I do for my own personal network.

New Airport Extreme in Bridge mode -- some devices have no internet access

I just bought a new Airport Extreme as my old one which was probably 7 years old required restarting every day. My setup is as follows: DSL cable modem to Linksys Router (for a long set of convoluted reasons, I can't remove this layer) and then Airport Extreme. This is how I had it set up with my old one. The only difference is I recently started looking into using "Back to the Mac" on MobileMe and in order for it to work, I set my new Airport Extreme to Bridge mode due to dual NAT. I have an iMac, PC, MBP, MBA, iphone 4, AppleTV and ipad. All was working fine last night when I set it up. 24 hours later, for some odd reasons, I can't have my PC accessing the wireless network at the same time. If I did, it would knock my iMac off the network and says some other device is using the same IP address. For a while, only my iMac (my main computer) can access it and even my iphone can't. At this very moment, my iphone, imac and MBP all have access to the wireless network. My MBA and iPad has no internet connection. I've restarted Airport Extreme, Linksys, and modem more than once... If I switch back to "Use Public IP Address" instead of Bridge mode, everything works except for "Back to the Mac"... Help!

Hey Bob, Thanks...I have already repeated that multiple times yesterday and today but to no avail. I tried to get into the Linksys router control panel but unfortunately we can't remember the username and password (the router is not mine). The make things even more complicated, the router is actually part of the internet package provided by the ISP and they use a PPPoE to log in. Theoretically, we could do a hard reset but the problem is the ISP will not release the PPPoE information unless we sign a long and complicated form saying we want to bypass their Linksys router. We can do that but this process will take days and weeks... Our ISP confirmed that the Linksys router is set to max out at 5 DHCP but we can only connect 3 machines at a time. They are coming out to take a look tomorrow but in the meantime I have reset the Airport Extreme to "Distribute a Public IP Address" mode which will allow access to all computers/devices. What's even more weird is that if I did the Bridge mode, it messes up the Linksys router's own network as well. We can't even just sign into that network... Any ideas why?

Airport Express 801.11b/g and the neverending, unconfigurable blinking amber light

Gather round and let me tell you a tale. Once upon a time I bought an airport express 801.11b/g and I was very happy to use it for airtunes, extending a wi-fi network and the wireless printing capabilities. One day, it beagn flashing a scaaaary amber light. The base station stopped showing up in my airport utility 5.6 as well. The only way to get it to show up, was to hard reset it, and lose all the configurations I once enjoyed happily. After the hard reset, It would show up in the utility, and I would reconfigure it to do all its cool things it once did, and it would restart. But sadly, after restarting the blinking amber light came on a again. It would also not show up in the utility unless I hard reset it again, and the same thing happened over and over and over until I felt like pulling my hair out.
I decided to get another airport express a few months later, ultimately deciding that the unit must have just been defective. Bad luck. But - the second unit literally went through the SAME EXACT THING. Worked for a while, then onto the blinking amber light- hard reset- reconfigure-blinking amber light thing. Over and over and over. Just like the first one. The end.
So - either Im missing something totally fundamental or I had the misfortune of getting two defective units in a row. Both were bought used from different places, and worked "fine" for previous owners. Am I corrupting these things or what?
I have spent literally hours trying all the resets, configuring "workarounds" and nothing works. For both of them.
What do I do with these two devices? I don't need two shiny white paperweights.
Please advise,
Thanks.

Yes. It seems an integral part of the set up process though, you don't have to seperately configure the airport do you?
My wireless security is WPA/WPA2 Personal. When I go through the standard network set up, it automatically enters my wireless security settings. So it doesn't really seem to give an option to specifically set that option on the airport if that makes sense?
I did go through maunual mode to try that with the same result:
If I'm using the airports own network and connect to the wifi, no security, then I'm getting airtunes from my macbook. Of course this means it's plugged into my router via ethernet which isn't any use to me as I want it in my kitchen, and would rather not limit my apple devices to b/g when I have a decent N router, and would also mean running a huge ethernet cable across my house!
The seller has said it worked for him but he's not up to scratch on his tech, so if I'm sure it's malfunctioning he'll refund. Obviously this is great news and he seems like a very nice guy so I want to be certain it's not me malfunctioning before I send it back!
So in summary I have it functioning on it's OWN network:
Wireless mode: Create a wireless network
Wireless network name: Apple Network XXXXXX
etc
Once 'wireless mode' is switched from 'create a wireless network' to 'join a wireless network' I select my current WiFi, security and password, checked the TCP/IP settings all good. Select 'Update'. Get the warning that device and network will be temporarily unavailable am I sure I want to continue. Then it goes through the same as before, says it's succesful, restarts to flashing amber with no way of accessing it unless I hard reset.
Thanks for the help so far...
