10.4.5 - mac mini can't connect to network via airport since upgrade

I've been experiencing problems since upgrading to 10.4.3. Mainly, I've noticed that I can't easily connect to our wireless home network all the time. The pattern has been that I start by shutting down my computer completely. When I start up it again, it can't connect to the network. I have to create a new profile and then it will connect. That was buggy, but at least I found a hack. However, since upgrading to 10.4.5, I can't connect to our home network at all. The Internet Connect application says that I am connected to the base station, however I can't connect to the outside world via a shell, browser or email application. Our network is secured with a WEP and the base station is a D-Link. I searched the forums for some tips, but didn't find anything. Pointers appreciated.

Be very careful about the sequence you do it. You must make sure that the airport connection is turned off (i.e. the airport menu icon looks more like a profiled eyeball without the iris than a series of lines like the towers of hanoi). Then create a new location in the Airport network preference, and make sure that these settings are there under Options
1. Keep looking for recent networks
2. Automatically add new networks to the preferred network list.
3. Change the status of Enable interference robustness.
And by default, join preferred networks in the Airport location.

Can you connect iPad to Mac mini, Can you connect iPad to Mac mini

Can you connect iPad to Mac mini, Can you connect iPad to Mac mini?

Every Mac Mini has a USB port. Every Mac Mini can run iTunes. The only catch is that you need to be running Mac OS X 10.5.8 (Leopard) or later. So in general, yes, an iPad can connect to a Mac Mini.

2005 Mac Mini, can this connect this wirelessly to my home network as an iTunes server

I have acquired a 2005 Mac Mini which appears to need direct cable connection to my router to access the internet. Is there a way around this that I can modify to access my home network wirelessly so I can use this as a stable location for my itunes library rather than my macbook pro. The Mac mini is located in a room upstairs but my router is situated in the lounge alongside my Apple TV. I want to try and get the mac mini to be the storage location for itunes that my apple tv will use.
Would the addition of an airport express or the like be a solution or am I barking up the wrong tree. Due to the age, is it likely that the mac mini can be used as a mini desktop only rather than as a file server?
Any help with this would be greatly appreciated, as you have probably gathered, I am an apple novice

Per this
http://en.wikipedia.org/wiki/Mac_Mini
an internal wifi card was optional.
You need a USN wifi stict that is compatible with your Mac. This one shuld work

It says:
Supports Windows , ME, 2000, XP, vista , windows 7,MAC OS 10.X, Linux
Just mak sure that what yo get works with OSX 10.4.11 or 10.5.8. Your G4 Mini can only go to 10.5.8

HT4941 how many mac mini can you connect to a thunder bolt display

how many mac minis can you you connect to a thunder bolt display and if so how do you switch between them

Here's the official page on connection options (you can connect one computer to a display).
http://support.apple.com/kb/HT4885
I've read elsewhere that you can connect two computers to the Thunderbolt Display, but you can't switch between them per se. You can only power up one at a time. Anyone, feel free to correct me on this, but my understanding is this is not an officially supported configuration.

MBP no longer connects to network via Airport

today my MBP will not connect to my network via airport. Several other apple devices connect to the network no problem. MBP connects to the network OK via ethernet cable.
When I try to connect it just keep prompting for network password & user password, generates spinning wheel but then returns invalid password dialogue box. Tried several times and no success - occasionally there is an additional dialogue box " Apple80211agent......."
Pass word is fine as 5 other devices connect without any issue. What is going on?
Incidentally, just thought to create another Airport connection and hey presto it connects.
Still confused.

Your local LAN runs through your router.
All your ethernet ports, and your modem and router, should be behind and filtered from excess current. That means a UPS generally. And run input line thru UPS (coax) first, then run RJ45 back through UPS again (there can still be excess surge or current on the line).
Modems and routers can be compromised by surge outage or storm. So can ethernet ports.
You have two ethernet ports and you tried with both also.
What you did not do that I would have added is SMC Reset / Reset NVRAM/PRAM.
This is what I have had for the last year, very nice and stronger signals thruout the house.

Mac mini can't connect to wireless network

I have a wireless network and 3 macs (ibook, macbookpro and mini). My ibook and macbookpro can connect to the network no problem. However the macmini (2010, extreme card) sees the network but connection fails. So I assume (?) the card is OK since the network is detected.
Any ideas?
Thanks

Was your Mac Mini ever able to access your wireless network or did it just stop working recently?
I have been using ethernet since it was purchased. Only recently decided to test the wireless.
Can it see other networks as well? If so, are any of them available to you to let your Mini connect to?
There is only one available
Using the System Profiler on the Mini, please provide the following AirPort information:
Under Network > AirPort > Interfaces:
Card Type
Supported PHY Modes
Card Type: Airport Extreme (0x14E4, 0x93)
Supported PHY Modes 802.11 a/b/g/n
Under Current Network Information for your wireless network:

Mac mini unable to connect to internet via router

The macmini(no airport) is connected using an ethernet cable and a netgear powerline ethernet adaptor.

Hi Dan
Have you confirmed that the Netgear Powerline adaptor works fine with other computers on your network?
On your mini, if you go into System Preferences - Network - Built-in Ethernet, what are your TCP/IP settings? Are they the same as for the iMac?

Mac Mini won't connect to internet with airport

Hello All,
I have a three year old Mac Mini 1.83 GHz Intel Core 2 Duo at my office. We all use macs and connect to the internet using a Time Capsule (Simultaneous Dual Band II). Everyone else's computers are connecting to the internet and working just fine, but my computer constantly keeps failing to connect properly. I have to continually reboot my computer to get access. It will connect and stay connected for a little while, but then quit working all of a sudden again. I would say it disconnects about 10-15 times during the day. When I open up the diagnostic utility, it shows the following:
Airport - Green Light
Airport Settings - Green Light
Network Settings - Green Light
ISP - Failed
Internet - Failed
Server - Failed
Whenever I start having problems, everyone else's computers are connected and working just fine. I cannot figure out what the problem is and why my computer keeps showing that i'm connected, but won't let me access the internet. This problem just started a few weeks ago, but it is getting worse because it is starting to happen more frequently. Any help would be greatly appreciated. Thank you.

With the information that you have provided in your post, it seems clear that the Time Capsule, which is providing the wireless network, is working just fine, providing a good wireless signal to the area. Since that's the case, there is really not any adjustment or change to the Time Capsule that we can recommend.
You might look for sources of wireless interference like cordless phones or other electronics that may be in close proximity to the Mac Mini, or obvious obstructions in the signal path, particularly any metal objects like a filing cabinet or shelving system.
Other than that, we would recommend that you post in the Mac Mini forum for some possible answers, or the forum for the operating system that you are running on the Mac Mini. Start here and select the area(s) that you need.
https://discussions.apple.com/index.jspa
It's always possible of course, that the wireless card in the Mac Mini is failing, or the internal antenna connector has an intermittment connection, but we'll leave that diagnosis to the experts in the forums for the Mac Mini or your operating system.
If we missed something that would point to the Time Capsule as the source of connection problems with the Mac Mini, please let us know.

Mac Pro no longer connects to network via ethernet.

Since coing back from Thanksgiving break and my Mac Pro 1,1 will no longer connect to my router through via ethernet. This means I can neither connect to internet nor connect to devices like my laptop and Apple TV. Strangely, I can still connect to my Mac Pro from these devices to share screen, play audio/video through iTunes, etc. In Network Settings, I still have a green dot, and I still get an IP address assigned (though I usually use a fixed IP). If I go into my router (Netgear WNDR4000), the router tells me that the Mac Pro 1,1 is connected to the network.
I already have tried the following solutions:
· Restarting router, modem, and computer
· Making a new location in Network Settings
· Trying different ethernet ports
Please Help!

Can't connect to wireless via Airport - Other's on my network can though :/

I woke up this morning to no internet on my mac. I usually use Airport, and it usually automatically connects, but today it made me type in my WEP key again, so I did, and still no internet. I have FiO's so I went on Verizon's chat service and they said it wasn't the Router because my xbox, other pc's, etc - were connected via wireless network, so it had to be my mac. Everytime I try to connect, it picks up the wirless network, I type in my WEP key and the Airport icon get's 5 bars, but then when I open up my browser, an exclamation comes up over the sign and it says "No internet connection". Just a little side note, it said that the airport doesn't have an IP address, and sometimes it say's it does, but because it was automatically assigned, it can't connect. Also, the DNS tab, under System Preferences > Network > Advanced, shows no ip's it's just all blank. I have a 2007 Macbook. I called up Apple and before I could even tell them my name, they told me I was un-eligible for help and hung up on me, great people they are. If I could, I would take this mac back and get my $1150 I paid for it, back. So now this is my last resort. Please post if you have any idea how to fix this. By the way: I am on an ethernet cable, so the internet and wireless obviously works. It has to be my mac, right?

I was having the same problem with the wifi not connecting to our home network on only one of our Macbooks. It kept giving itself a self assigned ip address. Everything else would connect fine to the home network and the computer with the problem connected fine to every other network aside from our home wifi. After reading this thread and trying everything on it, this is what finally fixed it: I didn't have anything under the 802.1x tab either. So I:
Turned the Airport off and completely deleted the Airport in network preferences.
Then I went to keychain access and deleted EVERY wifi network password saved under both Login and System.
I turned the computer off and removed the battery and did the SMC reset by holding down the power button for 5 seconds.
When I restarted the computer, I reset the PRAM by holding down OPTION, COMMAND, P, and R at the same time RIGHT AFTER I pushed the power button to turn it on and before the grey screen appeared.
It reset and when the computer was back on, I added the airport again and joined my home WEP wfi network. It worked perfectly! Now I don't know if all of these steps are required to fix the problem but this is what worked for me. The Macbook with the problem was a black Macbook running 10.6.8. Good luck!

Can't connect to Internet via Airport

I have a PPPOE ISP account. Before upgrade to Lepoard, just fine. Now I can only connect to internet using cable via my router moderm. I cannot connect my wireless router.
The wireless router will appear to be connected but it said self assigned IP. If I hardcode an IP eg. 192.168.11.2 to it. The Airport status will become connected but still cannot dial into my PPPOE account. An message no PPPOE service will appear. But if I plug in the LAN cable, everything work fine. Why this happen? My wireless router work fine with my Window XP and my Mac (before upgrade to Lepoard) What configuration should I change? I am an idot to networking. I have download all patch and has tried boot to safe mode etc.
Anyone can help?

By power downs do you mean Sleep?
One thing that might work is to set the IP to Static in Network>Configure IPv4>DHCP with Manual Address.

Can't connect to iDisk via AirPort Extreme

I can't connect to iDisk if I have an Extreme in my network path.
Connection that will work:
Motorola cable modem -> Netgear Hub -> iMac -> iDisk
or
Motorola cable modem -> iMac -> iDisk
Connection that doesn't work:
Motorla Cable modem -> Airport Extreme -> Netgar Hub -> Mac -> iDisk
or
Motorla Cable modem -> Airport Extreme -> iMac
or
Motorla Cable modem -> Airport Extreme -> Dell D610
Oddly enough this will work:
Motorla Cable modem -> Airport Extreme ->Dell D610 -> VPN to Work network connection -> iDisk
This problem holds through with or without WEP Security.
Software: iMac 10.4.7 and Extreme V5.7 and it is setup as a WDS base station I need to extend my network to an Express.
Any thoughts? I have not found any problem like this on these pages. (As best as I could see anyway.)
iMac Mac OS X (10.4.6)
iMac Mac OS X (10.4.6)

Looking over your original post again, I think I might have misunderstood you the first time. If I understand you correctly, your Vista laptop can see the wireless network and connect to it (so you have access to the Internet), but you cannot see the Airport Extreme Base Station when using Airport Utility.
If your Internet connectivity is not an issue and it's just that you can't see the base station in Airport Utility to configure it, try using an ethernet cable to connect your Vista laptop to one of the LAN ports and see if the base station shows up in Airport Utility then.

Can't connect to internet via airport after switching off

I can create a new network connection and successfully connect to the net. However when I come back to surf later after a couple of power downs it will not connect. My mac can see the network, recognise the name and security type but will not allow connection, even when I retype any password accessing via other network. I've tried setting up a location, used it once but on power back the same issue happens. I can surf via a LAN cable no problem. Help!

Can't connect to network via iPad

I recently bought an Actiontec E2500 router/modem. My MAC Book Pro connected easily to the interent
via Verizon DSL and the modem/router works well. Unfortunately when I try to choose a wi - fi network for my iPad
(CB36N) it says "unable to connect to network" because the temporary admin password on the back of the modem does not work.
A password from Verizon also does not work. Actiontec said go to 192.168.0.1 to find a password but although there are two sites related to this product, they do not mention the word "password". Both companies don't seem to even understand my question!! The Actiontec guy said maybe my iPad isn't working! (it's brand new and works fine) Verizon has offered to send a tech to my house (I would have to take off work and wait from 8AM to 7PM) which seems ridiculous and a waste of time. I'm sure this can be resolved in a better way. Any thoughts? The word "Admin" does not work either. Thanks in advance.

Hi Jenroses,
I would suggest backing up your iPad and updating it to the latest iOS, which is iOS 6.1.4
The links below should help you with this:
Choosing an iOS backup method (Should I use iTunes or iCloud to back up my iOS device?)
iOS: How to update your iPhone, iPad, or iPod touch
iOS: Troubleshooting Wi-Fi networks and connections
Be sure that you are in range of your Wi-Fi router (access point).
Tap Settings > Wi-Fi and turn Wi-Fi off and then on again.If unable to do so, see this article.
Confirm that your Wi-Fi router and Cable or DSL modem are connected to power, turned on, and indicate that they are connected to the Internet.If not, refer to your network administrator or ISP for assistance.
Restart your iOS device.
Tap Settings > Wi-Fi and locate the Wi-Fi network to which you are connected. Then tap the blue dot and choose Forget this Network. Try to connect to your desired Wi-Fi network again.
Note: You will need to enter your Wi-Fi password again if your desired network requires one.
Turn your Wi-Fi router off and then on again2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2.For AirPort Base Stations, see this article for information about firmware updates.
If your issue is still unresolved
Follow the steps below for the issue you are experiencing.
Unable to locate a Wi-Fi network
Unable to connect to a Wi-Fi network
Wi-Fi disconnects, or signal strength is less than expected
Unable to access the Internet while connected to Wi-Fi
Unable to automatically connect to Wi-Fi
I hope this information helps ....
Have a great day!
