Airport network start up problem

As I'm setting up my new Airport Extreme with Time Capsule, all is good until I attempt to join the wireless network I've created. Then I get the Unable to Join Airport Network window. My wife's PC connects with no problem and I'm using a PC on an Ethernet line from the same ISP right now. So, any idea why the IMac can't connect to the Airport?

Hello Roxy and welcome to the Apple forums.
First we need to know what you have.
1. Airport Extreme Base Station
or
2. Time Capsule
The above 2 units are different.
Do you have both? or just one?
Let us know what you have so we can help you better.

Daisy Chained Airport Network Wireless Client Problem

It's a long distance from my cable modem to the last area in my house I want to establish a wireless network in, so I set up a three-Airport network, with a Time Capsule at the cable modem, connected to an Airport Extreme (wirelessly), which is connected to another Extreme (wirelessly). Airport Utility shows the three in a chained arrangement:
The problem I'm having is that the last Airport won't allow any wireless clients. It does allow several devices to connect to it with a wired connection, just fine. Any suggestions how I can allow the last Airport to extend my network wirelessly as well as wired?

When I add a few clients to the list with their Mac addresses and change the Unlimited settings to No Access, the Airport Express stops working.
The last AirPort is configured to "join" the wireless network....even if you think that it might be set to "extend" a wireless network. In this type of configuration, the last AirPort provides no wireless signal extension.....but.... the Ethernet ports are enabled.
If you want the last AirPort to extend the wireless signal coverage, it will need to be connected using a wired Ethernet connection to your main router.....or.....it will need to be moved much closer to the Time Capsule if you want to try to extend wirelessly.
Maybe they're all really connected in a hub-spoke arrangement after all, and Airport Utiity is just showing them wrong?
No, they are not configured in a hub-spoke setup. If they were, then both of the AirPort Extremes would be displayed as connecting directly to the Time Capsule.

Airport network + 1 admin account + 1 standard account on the same Mac

Hello,
I have not succeeded yet in finding in this forum any answer to my problem but I guess this is a quite familiar one and may be some of you could help.
My configuration:
1) one Imac G5 Power PC (OS 10.4.6) + 1 Airport Express base station with firmware 6.3 (mostly to play Itunes on distant loudspeakers and, sometimes, for Ethernet connection).
2) one domestic Airport network protected with a WAP key.
3) 1 admin user account + 1 standard user account, both on the same Mac.
My concern:
1) When I am connected to to the admin account, my Airport network starts automatically (especially, thanks to the configuration settings "automatically connect to to the last network used" (or smthg like that) => so far, so good.
2) When I try to connect to the standard account (even when the admin one is already started), I always receive a window for authentification requiring an admin name and password for Airport (com.apple.airport.allow.network.cha): at this time the Airport icon in the menu bar is gray (no signal nor no activity?) and, in the list of the possible networks, my own one is not marked (meaning "not started"). Of course, as soon as I key in the correct data in the authentification window, the AE network starts for the standard account session => this behavior concerns me since the interest of a standard account is to have it running without the support of the admin user.
3) Last but not least and very strange behavior: when I am at step 2) (connection to the standard account), if I do not fill immediately the authentification form and go back to the admin account, when coming back again to the standard one, the authentification window has disappeared and the AE network is already running => magic but not comfortable in a normal way of doing.
Is this a problem of configuration of the AE network or configuration of the user accounts or a keychain problem? I have investigated in all areas for a while but without success at this time. Hope some of you will be able to help.
Sincerely
Christophe

Hello again,
I have not received yet any answer to my initial post (see above) but, unfortunately, the troubles described keep going. I noticed that, some of you, seem to be very familiar with Airport troubleshooting. May be, some of you will be able to help.
In addition to my initial description here is the content of the authentification window and, especially, the system element which requires an admin password for the standard account. May be it could help for a better understanding of the problem and a better investigation:
" Authorization : com.apple.airport.allow.network.cha
Tool : airport (complete path = Imac G5 de myname / System / Library / PrivateFrameworks / Apple80211.framework / Resources / airport "
Looking forward to hearing from you.

Airport Network Options Problem

Hi All
I have just upgraded from 10.3 to 10.4.5 and have found a problem with the Airport Network prefs pane which I can't fix. Originally the interface to the Airport Networks pane was not showing correctly and was still setup as in 10.3. I only noticed this as I had another Mac running 10.4 and was copying the settings from it. The only way to fix this was to delete the Locations and start from scratch. After doing this everything seemed okay apart from the Options button in the Airport settings. When pushed it doesn't open anything. I don't want to do a reinstall for such a small problem so does anyone else know of a quick fix to solve this?
Thanks
Alec

Problem with 2 computers Airport network

While long time comfortable with Mac, I am novice with Airport/network.
I have a MacMini (with Airport card) and a new PowerBookPro (15" 2.2 Intel Core 2 Duo and Airport card). I have new Airport Extreme Base device and I have successfully set up wireless internet connection for both computers.
I have also successfully through Airport set up so my mini connects with MBP/sees the MBP on the Mini desktop, etc..
My problem is that I haven't done the +correct rain dance+ so that the MBP connects to see my Mac mini on the MBP.
No clue what is being done wrong, except: In Finder of Mini under Go --> Network the MBP is listed and I then connect through steps of that window.
However, on the MBP Finder under Go --> Network, I just get a "flash" and no menu window is displayed at all.
Strange to me that computer network gods are so easily accommodating one way (Mini connects with MBP via Go/Network) and totally absent in reverse (no connect of MBP via Go/Network with Mini).
I hope someone can guide me through the correct ritual so that the 2 computers can go both ways. TIA.

I solved my problem!
Looking in other discussion forums, I found workaround for the fact that when on MBP/Finder/Go/Network all I got was a flash and no window.
The recommended solution worked! To simply logout and then login on that MBP. This restored the Go windows and Network window showing my MacMini to connect with.
So now both computer go both ways.

How do I solve connection problems with Windows-PCs on a AirPort network?

I have a AirPort network with 1 AP Extreme (dual band) in bridge modeextended with two dualband AP Express and one 1st gen. AP Express. With only Macs all computers connect without problem, but when introducing PCs running Windows (7 or 8) on my wireless network both Windows and Macs often get problems getting an IP-adress from my router. When resetting my router problem is solved for a while.
Anyone with a solution?

You're going to have to be more specific with the issues, errors and diagnostic messages that you are encountering, and what particular configuration you are seeing to establish.
Screen sharing is available from Mac to Mac, and from Windows once you load a VNC client on the Windows box such as TightVNC or some other VNC client, and configure and connect it.
Here are some notes on getting Windows file clients to connect to a Mac OS X Server SMB Samba file server; you have to drop some of the Windows security requirements to allow it to connect to the Mac OS X Server box.
Microsoft Office Outlook isn't traditionally used with mail servers other than Microsoft Exchange Server. (While Outlook was good with Exchange Server and has likely gotten better over the years, it was classically rather poor when working with SMTP servers.) More commonly, Outlook Express (and now called Windows Mail) is used for this, or Mozilla Thunderbird, or another SMTP-capable mail client.
One of the first things you will want to ensure here is correct and functional DNS on your LAN; other services are entirely dependent on DNS, and your ISP DNS cannot provide valid DNS for a LAN behind a NAT device. Launch Terminal.app and issue the command sudo changeip -checkhostname and see if you get an indication that DNS is correct and no changes are required, or that there are DNS errors. (You will need to enter an administrative password for the sudo command to be accepted.)
To connect and use a mail server on the Internet, you'll need to have a public static IP address and a correct public DNS configuration, or (far less desirably, and rather more complex) a way to tunnel from a non-static IP address over to a mail gateway service of some sort. Having static IP and correct DNS is the usual approach.

Problems joining airport network... PLEASE HELP!

Hello...
I´m having problems joining an airport network, i realy hope u guys can help me... I tried everything...
I turn on my airport card and the airport finds the network i want to join... No problems with that...
I enter the password (i´m sure it´s the correct one) and it keeps saying "there was an error joining the airport network "Blablabla".
The type of security is WEP Passord...
Thank u for your attencion...

One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
Though sometimes not even that works and the HEX key must be used regardless.

Hi, KK93.
Sometimes a simple power cycle of the router and Mac can resolve the issue. However, try the steps in the article below to troubleshoot the Wi-Fi issue with your MacBook.

Airport Network not reconnecting automatically at computer start

Hi everybody,
Just purchased a new Airport Express because the old one was failing often.
At each start of the computer, I find a window : "None of your preferred network is available " with the list of all WiFi networks in the neighborhood.
Mine is listed as well, so I have to select it and click " JOIN" .
The previous Airport Express was not doing this. Did I miss a setting ?
Thank you in advance
Alain

Please try the following:
1. Delete Preferred Network(s)
o System Preferences > Network > AirPort > Advanced > AirPort tab
o Under "Preferred Networks," delete the network(s) you regularly use from the list.
2. Delete AirPort Keychain Entries
o Launch the "Keychain Access" application located in Applications/Utilties.
o Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
o Restart, or log out then back in.
3. Add Preferred Network(s)
o System Preferences > Network > AirPort > Advanced > AirPort tab
o Add the preferred network(s) using the "+" button.
o Restart or log out then back in.

"No airport networks were found" - setup problem

I'm trying to setup a new airport network with an AEBS. I plugged it in to the outlet and then plugged the cable modem ethernet cable into the AEBS. The light turns green. Then I open Airport Setup Utility and get the following message:
"No airport networks were found"
I then opened the Airport Admin Utility, and it is also unable to see the AEBS.
Any suggestions?

Okay, I updated the firmware to 6.3 and am now able to see the AEBS network. However, I can't connect to the Internet using the network I created in the Admin Utility.
The Network control pane says Aiport is active and connected to the Internet, but I can't get online. I have a Comcast cable high-speed Internet. I'm not exactly sure what my settings should be in Network?

Airport Express B/G : problems with manual IP configuration?

I don't know when it started, but I think it has something to do with one of te latest systemupdates or airport firmware updates.
Configuration :
- Airport Express N : only N, bridge mode, IP manual (192.168.1.7), roaming with Extreme N
- Airport Extreme N : only N, bridge mode, IP manual (192.168.1.35), roaming with Express N
- Airport Express B/G (older one) : B/G compatible, bridge mode, IP manual (192.168.1.8), no roaming, just stand alone.
All the airports are wired connected to a 10/100 switch.
No internet configuration on these airports, I'm using a separated router, also connected to the switch.
Problem : The airport Express B/G dissapears from the network : from time to time not visible in the airport utility program, from time to time not visible in iTunes (airtunes). In spite of these problems, he is always visible in the airport network menu. An IP ping works just fine.
When I change the IP configuration of the Airport Extreme B/G from manual to DHCP, there is NO problem anymore.
No problems with the Airport Express N an Airport Extreme N.
Are there other users with the same problem?
Thanks in advance.

question: i below what should i do ?
1) put a cable from my cablemodem to the airport extreme bs;
2) put a cable the airport extreme bs to the airport express bs.
Yes on both. Your network configuration would look something like the following:
Modem > (Ethernet) > \[WAN port] AEBSn \[LAN port] > (Ethernet) > AX
do i have to reset the modems and are there any setting i should be aware of ?
Yes, it's always a good idea to both reset both base stations and, after doing so and before configuring them, perform a complete power recycle of your network equipment.
So in this case ...
o Power-down the modem, AEBSn, AX, & computers. (Order is not critical.)
o Reset both the AEBSn & AX. (Again, order is not critical.)
o Power-down each base station after performing a successful reset.
o Power-up the modem; wait at least 15 minutes.
o Power-up the AEBSn; wait at least 10 minutes.
o Plug-in the AX; wait at least 5 minutes.
o Power-up your computer(s).
o Use the AirPort Utility to reconfigure both base stations as required.

Another airport connecting to internet problem! Please help!

Hi, I'm having a problem connecting to the internet on my iMac G5 running OS 10.5.8.
It initially started happening on and off after I upgraded from 10.4, now it happens all the time.
Airport connects to the network (full 5 bars and I can see the other machines on the network), but can't connect to the internet. When I run Network Diagnostics, I only get as far as Select Airport network, but it keeps scanning forever but doesn't find the network. Meanwhile my iBook G4 and a PowerMac on the same network connect no problem.
I get the Self Assigned IP address message in network preferences.
I have searched the forums for this problem, and found lots of other people having the same problem, but none of the suggested fixes have worked. The only thing I can't do is reboot the modem as it's my landlords network and I don't have access to it.
Things I have tried include:
-turning airport on and off
-deleting the airport preferences plist file from system preferences and rebooting
-deleting airport from network preferences and adding it again
-deleting all locations and creating a new one
-using manual dhcp and putting in an ip address same as the ibook with 1 extra number at the end
-turning of the firewall
-rebooting rebooting rebooting
None of the above works. Can anyone can suggest any thing else? It's driving me crazy! I know there are lots of other posts on this topic but I think I tried all of the fixes suggested without any success.
Thanks

There is a fair chance it's a problem with the DNS settings your ISP uses. Here is what I'd recommend.
1. System preferences
2. Network
3. Click Advanced
4. Click DNS tab
5. Click + sign
6. Add 208.67.222.222
7. Click + sign
8. Add 208.67.220.220
9. Click OK.
10. Exit System Preferences
11. Try out your iMac and report what happened.
Regards,
Roger

Mac to mac copy slows down over internal airport network

This is a strange problem but here goes...
Some useful background info:
I have recently downloaded through the new Airport Express network I just created a file that was 212MB from a site on the internet in about 12 minutes or so which is pretty fast for a DSL connection.
The issue:
When I try to copy files from a PowerBook G4 running Leopard 10.5.2 to an iMac G5 running the same version of the OS, I see the same odd behavior (copying from Public folder to any folder on the iMac):
The copy starts in the finder just fine and seems to be going very fast as expected by an internal network copy but after some arbitrary amount of time, the copy slows down and eventually fails. The time to complete the transfer starts out really fast and eventually hits a brick wall where it slows down further and further.
Other notes: the copy I've been attempting is files and folder that are about 1GB total but I've tried it with small and large copies and this has worked fine in the past with Leopard and other OS'.
Sometimes, this slowdown occurs at 5MB into the copy, other times it doesn't happen until it gets about 50MB into the copy. Thew strange thing is, large files over the Internet are just fine as I mentioned above.
There's plenty of free space on the machine that I'm copying to but this happens repeatedly when I try to copy from one computer running Leopard to another.
I don't think this issue is related to the Airport Express because I recently created a new network to test this issue called Bedroom Airport Express. Previously, when I'd been successful performing these types of transfers, I was using the LinkSys WRT54G's built in wireless capabilities and had no issues using Go To and entering the computer's IP address.
When this issue started to occur, I was baffled so I hooked up the extra Airport Express I had lying around and I'm still seeing the same issue despite the Internet transfers working like gangbusters.
The router is still the WRT54G on AT&T's DSL network using DHCP and there's no special config., other than that I had to re-IP the internal network to 192.168.199.1 for work related reasons but that's about it.
The MTU had to be increased to 1492 for the internet to work properly when I got my first WRT54G [an older version of this device that I replaced very recently with a new one]. The firm ware version of the router is v8.00.2 and the Airport Express has been recently updated to the latest firmware available (and this issue was occurring before the firmware upgrade as I added the Airport Express as an troubleshooting method).
Does anyone know where I should begin to try to resolve this issue? I've tried LinkSys tech suppport and I still get "we're not able to provide Mac tech support" reply despite the fact that addressing the router is done via a webpage and the BSD guts under the hood. If anyone knows what if anything I can do to troubleshoot what the issue is, I would greatly appreciate the assistance.
This networking stuff is a bit of a black art to those of us that are dilletantes in this arena and I certainly qualify as a dabbler in this stuff.
Thanks in advance,
<DM/>

I'm new to the Apple discussions, although not new to Apple computers and I've seen that this post has received quite a few views but no responses. Maybe someone could direct me to the right place to post this, if this is not that place, or, suggest some terminal tools that I could use to troubleshoot the issue with the Airport network or LinkSys Router I'm using [WTR54G v.8.0.0.x]? Thanks in advance for any assistance anyone can provide to a networking noobie.

Connecting to my Airport network

Has anyone else experienced this issue.
I use my G4iBook at school and at home. I have two "locations" because at school I have to use a proxy server to connect to the internet at work.
When I get home, my iBook wants to connect with every wireless network in the neighborhood (most are not secure), except my Airport network - AEBS.
This issue started when I changed the password on my secure Airport network.
It's not a big problem, but it's annoying to have to choose my own Airport network every time I come home from work.

If you use your computer in several locations and you switch Networks then you will have to select your network at home.
Airport technology will pick up any Network that it is in range of, your computer will be able connect to any that are not protected. Same as when you get home you have been using it at work and when you get home, lets say you are in range of 4 different Networks how does it know which one to connect to. Remember you have been at work all day using a different network. It sees them all but doesn't know which one to use.

Unable to join Airport Network

I am being baffled by a network problem.
I have 2 Macs, a MBP 17 inch running Snow Leopard and an old Powerbook G4 running 10.4. Both connect to a no security (ie no password wireless) network at home. "Suddenly" the MBP will not join the wireless network (A DSL model D-Link). Error message when running diagnostics of "Unable to join Airport network.....". The G4 works just fine.
Have tried rebooting both devices ie the MBP and the D-Link. The MBP will work fine with a cable attached to the D-Link but not wirelessly!
Also, the MBP can see the Powerbook in the FINDER under "Shared".
Any ideas?
Thanks
BF

Yeah, thanks Bob, I got my MBP Safari to talk to D-Link via the http://10.1.1.1 address, put in a WEP password. Saved the changes and restarted the router. When I connect via Airport it asks for a password - I type it in then it times out. Then I went to the Powerbook and the Vista machine and they connected fine. I used my iphone and told it the password and it also worked fine.
I prefixed it on my MBP with $ and without $ - all to no avail. I am starting to think maybe the MBP wants a WPA password for some reason. It worked fine until last night! Very strange indeed. Any more ideas?
What gets me is that one moment it works and the next it is dead as a dodo...
