17" flat panel Mac can no longer get on my Airport Extreme network

My 17" G4 flat panel iMac can't get on my Airport Extreme network. It has been on the network for years. All of a sudden I can't get on my own network. The Airport extreme uses a WAP2 Security password. Everything else in my home is on this network ie. Blu-Ray players, Wii, Nintendo DS's, MacBook, Apple TV. The G4 doesn't even have WAP2 as an option! Where did the option go? I really don't wanna set up the network again with a WEP password(That's an option on the G4) and have to reset everything. What happened?

There were two 17" flat-panel G4 iMacs. The earlier of the two (Part# M8812LL/A) had an optional AirPort Card. This card only supports 802.11b and either the WEP or WPA security standards. It does not WPA2. This may be the reason the G4 is not able to connect to your wireless network if you have it configured for WPA2 Personal.
You will need to reconfigure the AirPort to use the "WPA/WPA2 Personal" option.

Why can't I get TC or Airport Extreme to work in my house?

I am very mad at myself for buying a TC in April and now the new one is out!! I had issues with connectivity with my Airport Extreme and purchased a TC in April thinking that the APE was on the way out and now the TC is doing the same thing....help!!
I live in an old house with lathe and plaster walls. The TC is in a closet on the stairwell that is central to the main floor. We have about 75Mbps download from Comcast but the wireless was getting flaky. Our iPads, and phones would just loose connectivity and a speedtest.com test would show maybe 6Mbps when we had the APE so we figured the answer was a new router. After we started seeing some of the same issues with the new TC, I have changed our set up to using the TC as the base station and have the APE (old one) set up in the livingroom as an extention.
I am still not sure this is the best way to run this and am really mad that Apple upgraded just after I purchased the TC. Should I just sell the TC and get the new version with hopes that the new antena will help my problem??
BTW, I work for IBM from home so I really need the internet to work to the max in order to get my job done.

I work for IBM from home
Kind of ironic.

It is the nature of technology.. whenever you buy you are going to be caught by the next wave of products.. let yourself off.. Apple are the most secretive company in the world. Although I was telling people to wait for a fair while before the announcement.
I live in an old house with lathe and plaster walls.
The heavier the materials and the higher the moisture content the worse wireless. Older houses often have water problems..
There is no certainty the new AC model will fix your problems.. and certainly not without AC clients.
If you have a 75Mbps connection my first test would be ethernet to the TC and test if you can get that.. wireless turned off on the computer and no other clients turned on. Make sure the TC is actually routing at full speed.. people have found the TC can be slow.
If the ethernet test fails, replace the TC with another brand router.. eg Asus or Netgear.. ones that take 3rd party firmware are my favourites..
Relegate the TC to backup duties in the local lan by bridging it to the router.
If ethernet is fine and wireless fails to connect fast enough.. do a proper wireless survey in your home.. use a wireless analysis software.. I don't know the paid one for Mac but istumber is ok.. inssider on pc is really good.
A full spectrum analysis would be even better but that requires more specialised stuff. But turn off everything you own that is wireless.. cordless phones, av senders, door bells, baby monitors, and the zillion other things that use unlicensed bands.
Do a full reset of the TC and set names, short, no spaces and pure alphanumeric for both 2.4 and 5ghz bands.. different names.. and set fixed channels and test each in turn.. non-overlapping at 2.4ghz, 1, 6, 11
For 5ghz down low, 36-40 and one of the high channels is enough.. 150 or greater.
If you own the house and you do work from home.. run ethernet.. and claim it on tax as business expense..
Anybody running business should run ethernet.
Wireless is for toys and hobbies .. the reliability of wireless is really not up to business standards. At least IMHO.. !!
If the business run wireless.. it comes with products that have the big C on them and cost thousands of dollars. Ask at your local Apple store what brand wireless equipment they run.. it aint apple.

Can't even get started with airport extreme

I have 2 windows vista computers on a Dlink router to a cable modem provided by my ISP. All of this is on the second floor of my house.
I want to be able to play airtunes via airport express downstairs with my stereo speakers. I could never get airport express to do this alone so I went to a retail store and was told by the MAC salesman I needed an Airport Extreme.
I tried connecting my airport extreme via ethernet cable to my router and got a flashing amber light. I followed the instructions but now airport utility will not even recognize the airport extreme not to mention that I haven't even been able to add the airport express.
I basically need help from step 1 as well as an overview of how I will be doing this.
Thanks

Hello cturnerlewis. Welcome to the Apple Discussions!
To be able to stream via AirTunes to the AirPort Express Base Station (AX) downstairs the AX just need to join an existing wireless network. If you current D-Link router is wireless, then the AirPort Extreme Base Station (AEBS) was NOT necessary. However, I will assume that it is not.
What you will want to do, in a nutshell, is the following two things:
1. Set up a wireless network with the AEBS, and
2. Configure the AX to join the AEBS's wireless network.
Here are the basic steps for both ...
Step 1: 802.11n AirPort Extreme Base Station Setup (AEBSn) w/Cable Modem
Perform a "hard" reset of the AEBSn.
o (ref: http://docs.info.apple.com/article.html?artnum=107451)
Modem/Router Power ReCycling
o Power-off the Cable modem, AEBSn, & computer(s); Wait at least 30 minutes.
o Power-on the Cable modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
Setup the AEBSn
Either connect to the AEBSn's wireless network or, temporarily, connect your computer directly (using an Ethernet cable) to one of the LAN ports of the AEBSn, and then, using the AirPort Utility in Manual Mode, check these settings:
AirPort - Base Station
o Base Station Name: <whatever you wish or use the default>
o Base Station Password: (optional)
o Contact: (optional)
o Location: (optional)
o Set time automatically (optional)
o Time Zone: <select your time zone>
o Status Light: Always On (Default)
o Allow configuration over Ethernet WAN port (unchecked)
o Advertise configuration globally using Bonjour (unchecked)
AirPort - Wireless
o Wireless Mode: Create a wireless network
o Network Name: <whatever you wish or use the default>
o Allow this network to be extended (unchecked)
o Radio Mode: 802.11n (802.11b/g compatible)
o Channel: Automatic
o Wireless Security: None
Internet - Internet Connection
o Connect Using: Ethernet
o Configure IPv4: Using DHCP
o IP Address: <provided by your ISP>
o Subnet Mask: <provided by your ISP>
o Router Address: <provided by your ISP>
o DNS Server(s): <provided by your ISP>
o Domain Name: <provided by your ISP>
o DHCP Client ID: (optional)
o Ethernet WAN Port: Automatic (Default)
o Connection Sharing: Share a public IP address
Once you have verified Internet access, I strongly suggest that you use wireless encryption (WPA or WPA2) to secure your network.
Step 2: AirPort Express Base Station (AX) - AirTunes Setup
Perform a "factory default" reset of the AX
o (ref: http://docs.info.apple.com/article.html?artnum=108044)
Either connect to the AX's wireless network or connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, make the following changes:
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <existing AEBSn's wireless network>
o Wireless Security: <select the encryption type of the existing wireless network>
o Wireless Password: <enter the existing wireless network password>
o Verify Password: <re-enter the existing wireless network password>
Music
o Enable AirTunes (checked)
o iTunes Speaker Name: <enter desired speaker name>
o iTunes Speaker Password: (optional)
o Verify Password: (optional)
o Click Update to write the new settings to the AX
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)

Can no longer configure modem in Airport Extreme Base Station

We've been using our AEBS to connect to our ISP via its internal modem for several years. Recently, I needed to update some ISP information for the modem connection and did so successfully using Airport Admin Utility. Two days later, tried to change additional settings, but AAU no longer shows "Modem (v.90)" as a "connect using" option on the Internet page. In fact, all of the options are greyed out except Ethernet, PPP over Ethernet and Airport (WDS). What happened?
I've reloaded and updated all of the Airport utilities, updated the AEBS firmware, power-cycled the AEBS . . . everything, but nothing fixed the problem.
I've tried this from two systems running 10.3.9 and one running 10.4.7.
I'm desperate. We live in the mountains of Colorado and until recently our only option for Internet access has been modem. Next week, however, we'll be installing a dish for access via an antenna on a nearby mountain. I'm concerned that I won't be able to reconfigure the AEBS for broadband. It's also possible that we'll still need to use the modem to connect to work, so I'd like to be able to switch AEBS configurations at will.
I'll be most grateful for any suggestions offered.
iMac G5 Mac OS X (10.3.9) also iMac G5 running 10.4.7 and a couple of laptops

Not yet. Maybe I'll try that next. The problem is that the 1-second reset only changes the password, but the 5-second really hard reset will wipe out all the settings and return the AEBS to default settings. If I still can't get to the modem configuration in AAU, then I've just lost all ability to connect to the Internet. (The modem in my computer got fried during a really, really bad lightning storm - zapper came in through the phone line even though it was connected through a surge suppressor - such is life on the Frontier!)
The modem in the AEBS is working because that's how I was connected to the Internet last night when I wrote the question, but I just can't configure it anymore.
I'll can give the hard reset a whack, but it makes me anxious. I may do better to just wait until my broadband link is installed and then configure the base station for Ethernet. At least that option seems to still be available.
Thanks for the response.

I can see my airport extreme network, but none of my devices (vista, ipad, iphone, ipod) can connect to it. Why?

I have set up my apple aiport extreme after moving and I can see the airport extreme light is green and I can see the airport extreme network name, but when I select the network, the device cannot connect to it. No error message appears, the device simply is in a constant state of trying to connect to the network.
I can easily connect to the non Airport Extreme network.
Can anyone help?

Try factory resetting, it often helps when changing location.

Since this upgrade to Firefox 31 on the mac I can no longer get to any HP iLo.

Since this upgrade to Firefox 31 on the mac I can no longer get to any HP iLo, does anybody know what happened with security certificates with this update? Firefox does not ask to accept the certificate anymore it just says there i an invalid certificate.
Issuer certificate is invalid. (Error code: sec_error_ca_cert_invalid)

Note that if you remove the cert8.db file that this removes all intermediate certificates that Firefox has stored and possible exceptions that you created in the paste as well (see also cert_override.txt).
You will have to leave libPKIX disabled for now if that makes it possible to access these websites.
A possibility is to create a button with the PrefBar extension to toggle the security.use_mozillapkix_verification pref when needed, so you can see which sites have issues with PKIX.
What kind of error message do you get when you visit these websites if there is still one?
Can you attach a screenshot of the technical details or possibly post a link if the site is publicly accessible (i.e. no authentication or signing on required)?

HT3669 With recent upgrade to my Mac I can no longer get supply report on ink status in my printer-light is blinking and unable to tell which cartridge needs replacing?

With the recent upgrade to my computer I can no longer get Supply reports from my printer: a red light is flashing and I don't know which ink cartridge needs replacing?

I happen to have an Epson printer as well - WorkForce 645 - that does show the supply levels.
Since I have one, I know that Apple recently updated the Epson printer software (less than two weeks ago). Do you have the latest software? If not, you can get it through the App Store or here:
http://support.apple.com/kb/DL1398
Try it if you don't currently have it. If you're not sure, you can download it - it can't hurt.

I can know longer get to my office files. I am running on a MAC

I can no longer get to my office files and email system

Hmm, sorry, I don't know anything about Inside GGP. But from that website it looks like there is some software you have to install on your computer. The "install" link won't load for me so I can't try it out, but it may be that whatever software it is, needs to be installed again. Or it may be incompatible with Firefox 4, if it was an extension written for Firefox 3 and the extension hasn't been updated yet.
You'll probably have the best luck talking to your office network administrator about the problem. Sorry that I wasn't able to be more helpful than that.
Good luck!

My Mac can no longer find my Time Capsule or my home network.

Hello, having had no problems for the first few months I can no longer get online. My Mac cannot find my network (but can find all of the other networks on my street) and cannot find the Time Capsule. The Time Capsule itself has a green light so I assume is working fine. My daughter knocked the ethernet cable from the the Time Capsule around the time it stopped working - could this be related? We also moved our cordless phone near to the Time Capsule around the same time - could this be the problem? Any help would be very much appreciated. Thanks.

Smokerz, thanks for the help. A couple of very basic questions to clarify (I am clueless about these things).
1. When you say power down the modem you mean unplug it? (I currently get my cable TV and phone through it as well).
2. How do I go about changing the channel on the router? (which I assume is the Time Capsule?).
Apologies for my ignorance and thanks for any help.

I can no longer get into my WRT150N1.1 router any longer since I switched to Clear

I switched to Clear wireless a few weeks ago and I can no longer get into my router to change the settings. This is a bummer because I now no longer have a secure connection. 192.168.1.1 no longer accesses the router, and I checked my IP address and it is (for clear I assume) 192.168.15.3. So I tried using 192.168.15.1 and it took me to Motorola WIMX CPE, (which I am assuming is the Clear webpage)
I am on a Mac running Intel chip. Any help would be appreciated.
Have tried getting in from my Ipad without any luck.
Thanks

The trick to make this work is
hold down the reset button for about 30 seconds, then unplug the device, while you are still holding down the reset button.
leave unplugged for about 5 seconds, while you are still holding down the reset button.
plug the unit back in, while you are still holding down the reset button.
after about 5 seconds, let go off the reset button.
go to the webpage of the router.
Now you can try to access the setup page of your Router, i think this should work and you should be able to access the setup page of your router and able to make the changes on your Router.

I can no longer get my complete bank statements online, and my bank blames the Safari update and tells me to switch to Firefox. Is there no other solution?

I can no longer get my complete bank statements online, and my bank blames the latest Safari update and tells me to switch to Firefox. Is there no other solution?

I would feel dreadful If I thought had caused you a problem. The warnings about Java are fully justified but providing you are communicating with a known source, and as I said, you disable it the moment you have finished, you should be safe.
It might also be worth asking your bank what problem they have and would it be the same if you were using Firefox, for example.
Like you, I am very security minded, in fact I won't even put my bank details on my Mac let alone run my account that way.

How do i sync my ipod touch to a new pc, as i can no longer get on my old laptop?

How do i sync my ipod touch to a new pc, as i can no longer get on my old laptop.

It has always been very basic to always maintain a backup copy of your computer for this very occasion.
Have you failed to do this? not good.
You can transfer itunes purchases form an ipod: File>Transfer Purchases
You can enter a unique contact and calendar entry on the computer. you should get the option to merge.
You can import any pics taken with the ipod, and e-mail any pics synced to the ipod to yourself.
The ipod is not a storage/backup device. It simply mirrors the selected content of the computer to which you sync.

I can no longer get Firefox to come up on my laptop

I have windows vista and had an update of firefox last week and since then I can no longer get firefox to load on my desktop. I downloaded it again and still no luck at all. right now I'm using IE which I do not like at all. Can you help me?
Thanks \Barbara

Possibly security software or their settings is preventing Firefox downloading, or is blocking its changes and installation. For that and other troubleshooting tips see
* [[software update failed]]
* [[firefox does not work]]
Are you able to locate the Firefox Installer file on your computer. If you need to download it again use
* http://www.mozilla.org/en-US/firefox/all.html
* and follow instructions for a clean install,
** do NOT use any option from Windows or Firefox to delete personal data,that will destroy passwords, bookmarks and other settings. It is the windows program folder that you may need to remove
