No DHCP for MacAir airport or ethernet, static IP fine
Hey dudes,
I have a MacAir that cannot get DHCP settings from my router. All other devices in the office can DHCP okay, including ones at home tunnelling in through my VPN access.
- If I use manual settings I can connect fine, but the minute I choose DHCP it results in 169 address.
- This affects both ethernet and airport
- This is the only device this happens with. the other devices (iPhones, iPads, Macs, PCs etc.) in the office work fine
- No MAC filtering on router
- router otherwise fine, giving DHCP to all devices and allowing VPN use for other users connecting from home
- if I bind an IP to the Mac address of the airport/ethernet adapter, it works as well.
So it's only as issue on the MacAir 10.6.6, and it's only a problem with 100% dynamic IPs from the router (i.e. no static or reserved)
Personally, I think that a security setting or network security setting are preventing the two from talking. I have a log file and I guess the bits that stand out for me, although I have little idea how to decipher most of this, are:
"ARP detect router got no response"
"lease terminated"

I have a MacAir that cannot get DHCP settings from my router.
Welcome to Apple's discussion groups.
It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".
6) In the folder /Library/Preferences ( not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.
By the way, in the future it might be better to post this type of question on the "Getting Online and Networking" section for your particular OS X version:

Bridge Mode or DHCP for two Airport Extreme via ethernet?
I have Two airport extreme setup in a six floor brownstone home in New York City. My verizon internet router is set up on the top floor with an airport extreme, my basement has the second airport extreme connected via ethernet wired from the top floor. I use DHCP from verizon internet. Do I set up my two airport extreme Bridge mode or DHCP?
Im having issues with my iphone not connecting through my basement airport extreme. Airport extreme status looks fine, green light and in working order.
Please help.Do I set up my two airport extreme Bridge mode or DHCP?
Bridge Mode. But, you don't have to worry about this, since the configuration wizard will do this for you automatically.

Best Practices for Using Airport Express to Stream iTunes via Ethernet
So I've been reading various posts about using Airport Express to stream iTunes and I've been reading various posts about using the Ethernet port on the Express. However, not sure I've yet found an inclusive listing of settings for both. Wondering if anyone out there has such a thing?
I have an (older) Aiport Express (802.11g, no 'n') running the latest Firmware (6.3, I believe). I have it lashed into my switch via a Cat 6 cable and the 3.5 stereo mini running out to RCA jacks into my RussSound (home audio system) amp. I'd like to make the Express ONLY a iTunes streaming device getting its network link over Ethernet (AirTunes). So, what does everyone suggest for best settings for turning on the Ethernet, turning off the WiFi and running AirTunes?
Thanks much in advance!
cheers
cp rootAirport > Wireless > Wireless mode "off"
Internet > Internet connection > Connect using "Ethernet", Configure IPv4 "via DHCP"
Music > Enable Airtunes
Enable Airtunes over Ethernet (if this choice appears).
When I first did this, the remote speakers didn't appear in iTunes. I poked around to see what I missed and couldn't find anything wrong, but the next time I ran iTunes the remote speakers appeared.
If you run into a firewall problem, make sure your OS X firewall is configured to "set access for specific services and applications": http://docs.info.apple.com/article.html?path=Mac/10.5/en/18503.html
Firmware 6.3 is correct for your Express. -
Configure DHCP for Airport Extreme to see PPoE on a Nyxel DSL Modem?
I would like to configure DHCP server for an Airport Extreme to see PPoE on a Nyxel DSL Modem?
Please perform factory default reset on the AEBS as follows:
Pull the power plug from the back of the AEBS
Hold in the reset button and keep holding it in for an additional 8-10 seconds while you plug the power back in to the AEBS
Release the reset button and allow 25-30 seconds for the AEBS to restart to a slow, blinking amber light
Connect an Ethernet cable from the Zyxel modem/router to the WAN port (circle icon) on the AEBS
Connect another spare Ethernet cable from your Mac to one of the LAN <=> ports on the AEBS
Open AirPort Utility, select the AEBS, and click Continue to follow the guided setup as follows:
Page 1 - Assign a device name and device password for the AEBS
Page 2- Select "Create a wireless network"
Page 3- Assign a name for the wireless network and a password for the wireless
Page 4 - Select Bridge Mode if not already selected
Page 5 - Setting should be Configure iPv4 Using DHCP. Not other info is needed
Page 6 - Summary of settings and click Update
Close AirPort Utility
Test out the wireless by disconnecting the spare Ethernet cable and then clicking the AirPort icon at the top of your Macs screen to Turn AirPort On.
Then click Join Other Network and Show Networks to locate your wireless network and log on using the wireless password
You should be good to go -
No dhcp for airport with parallels
hi,
i have a macbook and installed parallels yesterday. since i rebooted the mac, my airport can not get an address from dhcp. it only has a self assigned ip address. when i first ran paralles i chose bridged network. but now it makes no difference which network option i choose in parallels. there is no ip from dhcp for airport anymore. the ethernet card still works fine. but i`m afraid that once i use it with parallels the same thing will happen to it. anyone got an idea what to do about that?
greetz,
mikeHi, Mike / James Hetfield.
I don't mean to send you somewhere else, but this is a question you need to address with Parallels Support. I presume you've reviewed the Parallels User Guide concerning DHCP.
You might also want to search the AirPort & AirPort Express Discussions in case it has been addressed there, where AirPort-related questions are answered.
Good luck!

I am using SURPLUSMETER I am also using Apple Airport Time Capsule as my Router that is connected to my Satellite dish Internet Modem ... Now on the Surplusmeter I have the option for PPP Modem . Ethernet Port , Airport , Network Card , & Adaptor .
Which one can I use properly to monitor all the wireless Devices in my housActually, none of the options will do what you are looking for it to do. That is because, this application only monitors the traffic from the device it is hosted on. That would also mean that you would have to run a copy on each computer that will access the Internet on your network; note their individual usages, and then, combine them to get an idea of the total usage.
However, if you are only interested in the amount of Wi-Fi traffic that only your computer is seeing, then the "AirPort Network Card" option would be the correct choice. -
Airport express extends static ip?
Hi! I have an Airport express and I brought it to my dorm room. However it turns out that my dorm is giving me one static ip. How can i use my airport express to get that static ip and create/extend its own network with multiple ip adresses?
Unfortunately, AirPort Setup on the Mac will use a simple wizard type of setup, which does not allow a "manual setup" that you need.
The solution might be to go ahead and configure the Express using the setup wizard and once it has restarted, go back in using AirPort Utility to manually enter the Static settings on the AirPort Express.
Frankly, I have no idea if this will work or not since I cannot duplicate the setup here.
Connect the Ethernet cable to the WAN "O" port on the AirPort Express and power up the Express for a few minutes.
Hold in the reset button on the Expess for 9-10 seconds and release. Allow a full minute for the Express to restart to a slow, blinking amber light
Click the AirPort icon at the top of the Mac's screen and wait a few seconds for a listing New Airport Base Station to appear. Just below that, click on AirPort Express
AirPort Setup will open up automatically and take a minute to analyze the network and suggest a configuration...which will be wrong. Instead, you have to click the Other Options button and select the choice to Create a new wireless network. Click Next
Enter a wireless network name that you want to use and a device name for the AirPort Express. Enter a password for both the wireless network and AirPort Express device. Click Next.
Ignore the message to restart the modem and click Next
It will take a minute or two for AirPort Setup to configure the Express. When you see the message of Setup Complete , click Done.
Now click the AirPort icon at the top of the Mac's screen and select the wireless network name you named and enter the password to connect.
On your Mac, open Macintosh HD > Applications > Utiltiies > AirPort Utility
Click on the AirPort Express icon, then click Edit in the window that appears.
Click the Internet tab at the top of the next window
Change the setting for Connect Using from DHCP to Static
Enter the Static IP address that the school gave you in the iPv4 Address box
Enter the Subnet Mask in the Subnet Mask box
Enter the Router Address in the Router Address box
Leave other boxes blank or untouched
Click the Network tab at the top of the window
Click the Network Options button at the bottom of the window
Change the iPv4 DHCP Range to read 192.168.1.2 to 200
Click Save
Click Update at the lower right of the window and wait a full minute for the Express to restart. The Express will still be blinking amber. Check to see if you can get an Internet connection when you connect to the AirPort Express wireless nework and enter the password.
Post back on your progress. -
DHCP issue with Airport Express??
HI again, another home networking on a budget question for you all:
I want to create a home network with 2 seamless wireless access points and 2 wired points in two different rooms, on a budget of...well whatever I have my hands on right now. I want to be able to heavily use iTunes Home sharing as well as regular family home internet access.
Here is my setup:
DSL signal to Actiontec Modem/Router
From Actiontec, I broadcast Wifi, and connect a Mac G4 via ethernet, and a second ethernet line uses a powerline adapter to get signal to a Westell router/modem on the other end of the house (small house)
From Westell I connected a PC with no Wifi via ethernet and an Airport Express to broadcast the Wifi
Here are the settings changed from default:
Actiontec: changed ip range to start at 192.168.1.4
changed Wifi name and password
Westell: assigned static IP 192.168.1.2
disabled Wifi (doesn't have the same encryption)
Disabled DHCP (unchecked Private LAN DHCP Server enable)
Airport Express (1st Gen single band)
Wireless Mode: Create a Wireless Network
same Wifi name, password and encryption as Actiontec
Connect Using Ethernet
Connection Sharing:Off, Bridge Mode
Assigned static IP (not sure if I needed to) 192.168.1.3
(configure IPv4:Manually;IP address 192.168.1.3; router address 192.168.1.1; DNS server fields are blank and domain name is blank)
After hooking it all up, programming them all, I powered all the devices down and turned them on Actiontec first, then Westell, then AX.
Problems:
#1 Everything works fine until I plug in the Airport Express. Then ethernet still functions. However, I came home to an IP address conflict on my G4. Wifi will connect on SOME devices. An iPad connected fine, my iPhone 2 inches away would connect but never get a network signal and no internet;it stayed on cellular. As soon as I unplug the AX functionality is resumed but I don't get WiFi out as far as I'd like. Plus I am using it as a Print Server so I dont have to keep a computer on but I havent even attached that one yet.
#2 I can never seem to get all of my libraries to show up on HOme Sharing with iTunes. Specifically the PC connected to the Westell is missing even with the AX disconnected.
What did I miss??
Thank you for reading!!
JoeyDo I need to direct the AX to the 192.168.1.1 for DHCP or is it automatic? If so where?

Can I assign Airport Express to static IP Address?
Current setup - Airport Extreme attached to cable modem with 2 hard drives, Airport Express as print server in separate room with USB printer attached (just changed from Linksys with sometimes working NetGear print server). Clients accessing the network: 2 Windows XP, 1 Windows 7, iPads, iPhones, iPods, Apple TV, and sometimes a Mac Book.
The issue is that we don't keep the printing system on at all times (light switch with Express and printer plugged in); We dont't do much printing, and I print to pdf most of the time. As a result, the Express IP address changes every time it's turned on, requiring me to change the port settings on the printer properties before anyone can print. Is there a way to assign a static IP address to the Express so that I don't become tech support every time someone else in the house needs to print something?Is there a way to assign a static IP address to the Express so that I don't become tech support every time someone else in the house needs to print something?
Yes. The first order of business is to find the AirPort ID for the AirPort Express. You do this by opening AirPort Utility and clicking once on the Express. In the area to the right, jot down the AirPort ID.
Still in AirPort Utility, now click on the AirPort Extreme and click Manual Setup
Click the Internet icon
Click the DHCP tab below the Advanced icon
Look for the DHCP Reservations area and click on the + (plus) button at the bottom
Enter a description, for example AirPort Express
Click the MAC Address button and click Continue
Enter the AirPort ID in the MAC Address box
Assign the IP address you want the Express to use, for example 10.0.1.20
Click Done, then click Apply and the AirPort Extreme will restart
It would be a good idea to power cycle the entire network as follows:
Power everything down...all devices, order is not important
Power up the modem first, then AirPort Extreme, then Express, then devices -
Airport Express Ethernet WiFi bridging with 3rd-party wireless base?
I want to use an Airport Express as a substitute for a very-long Ethernet cable. Essentially, I want to connect a device (say, a computer) to the AE using an Ethernet cable, have the AE connect to a base station (not an Apple device) via wireless, and reach the network (Internet) on the other side of the base.
A diagram of the desired goal is at http://img.skitch.com/20091111-1j7a61eka32jqntm217wwg7d3g.jpg
I'm baffled. Here is what I've done:
-Reset the AE to factory defaults
-Connected a laptop to the AE via the Ethernet cable. Turn off my wireless (to make sure I'm talking to the AE via wired connection; this confirms the AE Ethernet port is working.)
-Configured the AE (via the Ethernet cable) in a variety of ways (see below), restarted it.
(alternately)
-Reset the AE to factory defaults
-Connected a laptop to the AE via wireless (connecting to the default-named network the AE creates on factory default reset)
-Configured the AE in a variety of ways, restarted it.
(This essentially suggests the AE is fully functional and not failed; I'm successfully able to connect to and configure the AE after factory default reset either wired, or wirelessly.)
I've tried various configuration attempts, but the one that seems to get closest - but still fails the goal is this:
-On "Airport / Wireless" tab: Join Wireless Network
--(I've entered my SSID for my network in the Wireless Network name field)
--(I've selected WEP 128 for security. I don't think I should be using WDS, given what I've seen elsewhere about WDS only working with an Apple Extreme.)
--(Of course, I've confirmed the passwords match)
-On "Internet / Internet Connection", the "Connect using" dropdown is disabled / greyed. This appears to only be enabled when I select "Participate in a WDS network" in the Wireless tab - which (as I said) I don't think I can use.
-On "Internet / Internet Connection", the Configure IPv4 is set to use DHCP
On restart, the AE successfully starts - it get's its IP address, the FIOS base station sees the device and lists it as online, and I can transmit audio successfully from iTunes to the stereo via the AE.
BUT, configured this way, the Ethernet port is not providing network connectivity to the device attached to the AE via the Ethernet cable -- the same Ethernet cable that was moments ago letting me talk to the AE to configure it is now not active. When I attach my MacBook to this cable and open System Preferences and look at the Ethernet connection, it shows as not even having a cable plugged in; there's no Ethernet link / carrier present. (Until I do a Factory Reset on the AE, after which it works fine again.)
Note: My AE is about 2-3 years old. I initially / previously had this configuration working just fine after I first installed the AE (after much pain, I recall). But I recently had Verizon installed, and in the process they put in a new base station. I seem to not be able to re-create the configuration I had that was working before.
Note 2: I'm attempting to use the wireless base station supplied by Verizon FIOS, which supports a ton of connectivity options - though it doesn't list (and therefore I'm assuming doesn't do) Apple's WDS.
Note 3: When I had it working before, I could have sworn the AE was also acting as a wireless base station that I could see in my available wireless networks listings, and was able to connect to the Internet wirelessly through it - as if it was a repeater of some kind. This isn't crucial; but it could be helpful in diagnosis.
Note 4: I think I may have previously had the AE connecting via another device: I also have a Netgear WG602v2 that was connected BaseRouter---Netgear((( ))) AE---Device (where --- is an Ethernet wire, and ((())) is a wireless link). HOWEVER, I can't be sure this is how it was working; this may have been a relic from attempts to get it working originally several years ago. It is not essential.
What am I missing?It sounds like you have an older 802.11 b/g AirPort Express, which as Duane mentions will not function as you would like.
The newer AirPort Express 802.11n has a function called ProxySTA which allows the device to join (according to the attached article) virtually any wireless network with an option to "enable ethernet clients".
While it is not possible to know whether any wireless network will be compatible with this feature, it has worked on a 2Wire and Netgear router that I've tried. Haven't tried Verizon Fios, so I can't assure you that this will work as you desire.
http://www.macworld.com/article/132754/2008/03/express11n.html
Another option might be to use a pair of ethernet powerline apapters, providing that everything is on the same master electrical circuit. In general, I've found the adapters to be more reliable and better performing than wireless, but of course, your mileage may vary. Post back if you need more info on this option. -
Trying to resolve a DHCP conflict involving Airport Extreme
I have my LAN set up so that the router hands out addresses with DHCP in the 192.168.1 range. Also on the network is an Airport Extreme (an older 11g model running the 5.7 firmware). I am having a terrible time trying to configure it so that it hands out addresses to its clients in the 10.0.1 range. No matter what I try, the Airport DHCP server is overridden by the DHCP server on the main router and a 192.168 address is assigned.
On the first configuration page of Airport Utility under the Internet tab, I have chosen Connect using Ethernet and DHCP. And I have chosen "Share a public IP address." Under the DHCP tab I've indicated beginning and ending IP addresses from 10.0.1.10 to 10.0.1.20. Why then when I connect to the airport with, say, my laptop, do I get a 192.168 address?
Any advice would be much appreciated.What you are trying to do is quite common, but perhaps the key is that the LAN with the DHCP router assigning 192.168.1 addresses must be connected to the AEBS via its WAN port.
In a default (configured from Factory Reset) scenario, the AEBS will request an IP address from the router via DHCP for itself, and will distribute IP addresses for its clients (wireless and via its LAN port) via DHCP from the pool you've specified if you have it set up to "Share a public IP address."
You can read more about setting up this type of network starting on page 24 of the Apple manual Designing AirPort Networks.
I suspect what's happening is the router is connected to your AirPort's LAN port, which causes a race condition between the two DHCP servers as to which will provide an address to new network devices. -
Airport Extreme Ethernet Unreliable
I am using two different Airport Express "N" 2nd Generation running 7.6.3 to connect via WAN Port over my CAT6 to a 10/100/1000 Ethernet switch connected to my ISP Modem/Router from two different rooms in my house.
Both devices are set to Create a Wireless Network and have Guest Network Turned off.
Both devices are configured to Connect over Ethernet and are in Bridge Mode - to avoid any risk of double NAT.
Neither device is configured to Allow this Network to be extended.
All of the Airports are configured with the same SSID and WPA2 settings to assist in ease of roaming for portable/mobile devices
(There is an extreme in the basement with an AppleTV and Xbox direct connected to it and working just fine)
Here is the problem - when I connect my Mac Mini or my Mac Book Air to the Ethernet port on either Airport Express, I get very unreliable, even unpredictable results. Very occasionally, the Macs will be able to recieve an IP from my ISP Router via DHCP and access the Internet, sometimes for an extended period of time and sometimes for just a minute or two. Other times I am unable to get an IP from ISP Router DHCP - and I get an error in my network settings for the Ethernet adaptors, usually a yellow indicator and no IP address or a self assigned IP address (I can still see the local Airport Express when this happens). The Link Integrity light is green and I have tested multiple cables. In fact sometimes the Link Integrity stays lit even after I unplug the Ethernet cable (weird unless it wants me to know that wireless client's are connected).
What I want is that in each of the rooms where I have the Airport Express I will be able to connect one computer on 10/100 Ethernet and support various Wifi clients as best as possible in that part of the house (iPad, Xbox, AppleTV, KindleFire, iPhone, Android)
My question: is the LAN Ethernet port intended to provide reliable access for a locally connected device when the WAN Ethernet port is used to get back to the ISP Router / DHCP Server? (It must be, this should be a legitmate use case... certainly works very well for the Airport Extreme!)
What am I doing wrong?I have a similar problem --exact same setup as you (Motorola cable modem > airport extreme > via ethernet to desktop > via wifi to MacBook, three iPod Touch, Time Capsule, and two iPhones). This started about a year ago: everything is going fine, then stops. Everything shows normal, green light (on both the airport and time capsules), all bars on wifi symbols, activity lights on modem flashing or steady as per normal, but no traffic flow. It happens as often as twice daily, is usually at least once a day, and can go for up to two weeks without happening at all. Following tips and advice on apple.com, I had the ISP (Comcast) replace my modem, and I have also, several times, wiped the airport express and completely reinstalled it. All to no avail. What to do? To get going again, I power down the airport express and then power it up; I used to also power cycle the modem, but that makes no difference. When the airport powers up, I get the yellow light (expected), and the "traffic" light on the modem is off; in a few seconds the yellow light goes to flashing, then green, and the modem traffic light resumes flashing as normal, and I'm back on the air. Comments?

Internet via airport AND ethernet dropping?
I have a new uMBP 13". When I connect to my home network it is the only computer on the network that will drop it's signal every 10 minutes at least. It searches for the network and reconnects a few seconds later but I have to manually search for the network and select.
I tried it with just the ethernet cable and airport turned off and the same thing happens.
I have an iMac connected wirelessly to the Netgear G router also running snow leopard which works fine.
I know there are discussions about airport dropping but this is airport and ethernet so where do I start with solving the problem?
ThanksHello William.
I've had similar problems, as described above. I have called AppleCare; I have found other threads on the forum(s) dealing with AirPort dropping connections; I have found much discussion of the subject on the web. There is a problem, and there appears to be no solution. Here is my related situation.
I have a MacBook Pro with Snow Leopard; an oldish Netgear wireless router; and my wife is connected to this little LAN with my old iBook running Leopard. That machine, with Leopard, never loses a connection whereas my Macbook Pro with SL loses the Airport connection approximately every 24 hours. After talking with the ISP and Netgear I solved that problem initially by rebooting the router. Now, I find, I have only to turn AirPort off and then on again and the connection is reestablished.
Meanwhile, I tried switching over to ethernet. I turned Airport off, and ethernet on, with an automatically assigned DNS address. Again, to my amazement, the connection (with the internet) was dropped, again, about every 24 hours--long about 9:30 in the evening, for me. To reconnect ethernet to the web I only had to click "renew DHCP address" under the Advance tab in the network panel. I.e., the behavior was analogous to what I went thru with Airport.
I have to think that 1) since this doesn't happen to my wife's machine on the same network running Leopard, and since 2) the same thing happens whether I'm using AirPort or Ethernet to connect to the web, that this is something systemic in SL's networking innards.
I went over all of the router's connections and settings (no timing out issue), and I upgraded its firmware successfully. I've done all the usual troubleshooting gimmicks, and, of course, I've discussed this with AppleCare. They haven't the foggiest. Since the problem only recurs in a longish circadian cycle it's not something that can be dealt with over the phone.
I have to believe there's something wrong with the networking software in Snow Leopard. And, for what it's worth, if you do a search for this on Google there is a great deal of similar discussion.
Now my solution is simply to use Airport and to turn the program on and off via the menu bar. Unfortunately it raises cain with syncing--"Mingler" and iCal and iCal's system syncing software run away with the CPU. But that's another thread!
All the best,
Alarik -
IMac self assigning IP addresses to both Airport and Ethernet, randomly
So, I've seen some others complain about their Macs randomly dropping the internet since around the 10.6.6 update. I've had the same issue. Sometimes it will go days with no problems, other times I have to reboot the iMac multiple times a day because it won't stay connected to the internet.
I finally looked in my network part of my System Preferences to see what that said, and to my shock I found that when the iMac deops from the network (the only thing on the network that drops, cell phones on WiFi are fine, Windows computers are fine, PS3 and Xbox 360 are fine) that it tells me that it has self assigned the IP addresses for the AirPort and/or Ethernet port.
Before I discovered this, my one friend joked it was a user error (PBKAC), but now that I can confirm it is not, I know this to be an OS X problem. Somewhere along the way to the 10.6.6 update, someone at Apple did something to the TCP/IP stack that seems to randomly affect users, and it has not been fixed, since.
Telling the computer to renew the DHCP lease from the router works sometimes, but not all the time. When it doesn't work, then the iMac needs to be rebooted in order to reconnect to the network.
I have a video showing the issue, as well. http://youtu.be/dhncotyiqS0
Apple, you need to fix this problem, even though it appears to not affect all users all the time.Hello djhalnon. Welcome to the Apple Discussions!
At any rate, while the Netgear had a "LAN IP Setup" screen allowing me to specify device addresses assigned by its DHCP service, I haven't found any such thing in the Airport Utility. Searching the 'Net didn't help much, because what I found doesn't coincide with what I can do in the utility.
The "equivalent" for the AirPort would be to utilize the "Reserve a DHCP IP address" feature in the AirPort Utility.
To do this, select the Manual Setup option in the AirPort Utility, and then:
1. Reserve a DHCP-provided IP address for the host device.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the host computer>
o IPv4 Address: <enter the desired IP address>
o Click Done. -
A few days ago, my Airport Express wireless connection stopped working. The network status lights for Internet and Servers are RED and indicate failure. My Ethernet connection works fine. Any idea what my problem is?
Thanks,
LivingSuccessYou could try a Safe Boot - restart holding down the shift key until the grey progress bar appears. When it's booted restart as normal from the Apple menu.
If that doesn't help you could try an SMC reset:
SMC Reset
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
