Can't connect to home wireless network using WPA2

Using PowerPC 10.4 Tiger.
Wireless is detected by airport card with pw prompt as WEP, but the network actually uses WPA2. Enter PW in prompt, but, of course, it was rejected.
My iPhone can get into my WiFI with WPA2 just fine.
What gives?
When network is configured for WEP, I can log in just fine, but can't take advantage of 802.11n (pre)

To use WPA2 requires an Airport Extreme card.
Run Apple System Profiler and under "Network" select "Airport Card" and it will tell you what type of Airport Card you have. If you don't have an Airport Extreme, you can't use WPA2.
Also, even if you have Airport Extreme cards in your computers, you may need to install extra software to enable use with 802.11n as described in this link

Suddenly can't connect to home wireless network

All of a sudden I can't connect to my home wireless network - always has worked perfectly. Now I get a box asking for the password, and although I type it in correctly it keeps saying "incorrect password." I thought I'd delete it and re-establish it, but it doesn't show up in the Managed Network settings. Any ideas what is going on?

On the problem computer, go to Control Panel > Printers and delete all instances of the printer.
Next, print a Wireless Network Test from the front of the printer (Network menu). Note the printer's IP address.
1. Make sure the printer is turned on and connected to your network. Verify that you can access the printer's internal web page by browsing to its IP address before continuing.
2. Click >> Start >> Control panel >> Printers.
3. Click the Add a printer
4. Select Local printer
5. Select Create a new port and select Standard TCP/IP Port and click Next button.
6. Under Device type, select TCP/IP Device. Under Hostname or IP address, enter the printer's IP address. Click Next.
7. Select Hewlett-Packard from the list of manufacturers and select and select your printer model. Click Next.
If your printer model was not listed, then select Have Disk, browse the HP CD that came with your printer and select the first file that starts with hp and ends with inf. Click Open then OK. Select your printer model. Click Next.
8. If you are asked, use the currently installed driver.
9. It will ask for the Printer name -- enter a new name or use the existing one. This will be the name of the printer that you select from other applications.
10. You may be asked to share the printer. Choose NO.
11. The Print Test Page box appears. Go ahead and print it.
12. Click Finish.

Airport problems - can't connect to home wireless network

I am stumped. i made the upgrade to quicktime ( it's not 7.4.5?) and suddenly airport didn't work. i input the wep password, and it returns, There was an error. When I try through Network Assist it says that the password is incorrect. Which of course, is not true. This same upgrade seems to have also created keychain issues.
I can connect without problem when hardwired through ethernet, however, I need the wireless to work.
Thanks, Thomas
ps. I'm using the same Linksys BEFW 11S4 that I have for years...

First of all, I want to say that i"m surprised in 24 hours or so, no one had anything to say on this subject. To help anyone else who has this problem, I will give the answer for I have solved the problem ( desperation has a way of forcing one to figure it out by the old trial and error method).
What occurred was that some how, the keychain document for my computer ( the home document, not login nor system) was inadvertently taken out. It was in another folder, but, I didn't realize what it was since it did not have .keychain in the name. Just my computer name. I got a hunch and put it back into place. And, suddenly Safari asked for the keychain password ( which had not been working either) and i put in the computers password and it was accepted. Airport was still not connect, but, when I manually input the wep password, it accepted it and turned on. What puzzles me is why the fact that there was no keychain home document, interfered with the manual inputting of the correct WEP password in airport. That I don't understand. Nonetheless, I am thrilled to be done with this all. And to have learned yet another mac secret. ( what ever that is). So, thanks to myself and I hope that someone is helped by what I have written here.

Can't connect to home wireless network

I have a Samsung Galaxy S3 and Verizon D-Link model DSL-2750B. Neither my phone or my husbands will connect to our Wi-Fi. Anyone have any idea why,it just keeps trying to authenticate but won't connect.

I just got new phones for both my husband and myself and doesn't work on either of the. I can get Wi-Fi @ work. The router is new and I have other wireless items that are running fine on it. It is Verizon D-Link DSL 2750B. I have tried setting up the phones with WPS, adding the MAC number directly into the site but nothing seems to work.

TS1398 have been connected to my wireless network using a netgear sky broadband router succesfully for a few weeks, suddenly can't connect, network is showing but no signal - all other wireless gadgets are connected just fine - including iphone - any idea

my ipad 4 has been connected to my wireless network using a netgear sky broadband router succesfully for a few weeks, suddenly can't connect, network is showing but no signal - all other wireless gadgets are connected just fine - including iphone - any ideas?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Can't connect to any wireless networks

My macbook pro can't connect to any wireless networks outside of my home router. I've just taken it on holiday and I can't use it in any free wireless coffee shops or hotels.
Whenever i select a network it shows it's connected with black bars in the radar icon but I cant access the internet or mail. Most frustrating is it's working fine in windows when I use boot camp.
I hope someone can help

Sometimes they can be stored in your Router and/or Modem, but having them in your Mac makes it so you don't have to rely on what's in or not in other's Routers.
I don't understand DNS...
Simply put.. you type in apple.com, your Browser goes out to a DNS Server somewhere with the request to link to the number of that name, then comes back with 17.254.3.183... if you ever wonder, you could type in that 17.254.3.183 IP, if it doesn't load Apple, then you are not connected to the Internet, yet if it does, and apple.com doesn't... then it's just that nothing is looking up the addy!

MacBook can't see my home wireless network after upgrade to OSX 10.8.5

After upgrading to OSX 10.8.5, my MacBook does not detect any wireless nertworks. My iPad and iPhone work fine, my router has been rebooted, WiFi is turned on, and the ethernet connection is how I am writing this message to you via broadband. There are a half dozen wireless networks in range (according to my iPhone) but the MacBook cannot find the router I am sitting next to. Any ideas on how to correct this issue?

It appears an SMC reset was required:
HT5815 I've just done the 10.8.5 update on my MacBook Pro end of 2008, and WiFi don't work after reboot... Impossible to activate it...
Here is your other post: MacBook can't see my home wireless network after upgrade to OSX 10.8.5
If you reply to it and marked it "solved", perhaps with a link to that post (copy and paste it, or just say you performed the SMC reset) it will help others find a solution. Thanks!

Upgraded 4s to iOS8 and can't connect to certain wireless networks anymore

I have an iPhone 4s that I updated to iOS 8. Prior to update, I was using iOS 7 (whatever the latest iteration was), and was able to connect to various wireless networks. Following the update, I am no longer able to connect to the wireless network at my place of work. It tries to connect, does so briefly, and give me an authentication request (screenshot attached). Blank username/passwords don't work, neither does the network name/password combo. Choosing cancel will revert the connection back to 3G.
To try and fix the problem, I have "forgotten" the connection, re-started the phone, and neither has worked I have reset my network connections, and it worked immediately after the reset. The phone was inactive for a while, and upon unlocking, it had reverted to 3G. When I tried to re-connect, it gave the same errors already stated.
I no longer have a back-up from before the upgrade, so I can't go back to 7. My wireless connection on my home network is fine. Nothing has changed with the work wireless since it was working with my iOS 7. It uses a WPA-Personal security, and there are several repeaters for the signal throughout the building.
What is going on and how can I fix it?

Set it up as new device, make sure all the apps are updated in the iTunes library and try to use iTunes to restore it again from the latest backup:

IPhone GPS location incorrect when connected to home wireless network

Hi all,
My iPhone GPS works well except when I am at home and connect to my wireless network. It always gives the same incorrect location about 3km away from my house. When I turn wireless off then the phone gives my correct location.
I think it is somehow getting confused when connecting to my airport. (I wonder if it is showing the location of the local telephone exchange?)
Has anyone else encountered this problem or found a solution? Or can I somehow tell my airport where it is?
Thanks!

A company called Skyhook Wireless maps WiFi and cell tower locations it scans. Apple uses this to help your GPS locate itself quicker. Here's how it works: http://www.skyhookwireless.com/inaction/apple.php
If your WiFi has not been scanned properly, you can submit a WiFi location update by going here: http://www.skyhookwireless.com/howitworks/submit_ap.php

Can't connect to home wireless, connection failed.

After browsing these forums for a few hours and others alike I can't seem to find anyone with a similar problem to mine. Which is quite simply to connect to my home wireless router.
The problem started after returning home from a weekend away, I chose to turn my Mac off completely whilst I was away.
Upon booting my Mac up, it did not connect to my wireless network. I checked my iPhone to see if that was connected which it was. So as a quick thought I rebooted my router which had no effect. I checked my PS3 to see if that still connected and it does, to which I booted up bootcamp which is also connecting fine which removes hardware problems from the list.
My Wi-Fi is on, the router is broadcasting and there is no interfering channels. All it says when I try and connect is connection failed.
I've tried many different things such as removing the network from the known wireless network list, removed the network from keychain, rebooted my Mac several times, cleared PRAM. All to no effect.
Am I missing something painstakingly obvious?
Thanks
Matt
I have a MacBook Pro Retina (Oct 2013) running the latest Mavericks

Please take all the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Run Software Update and install all available updates for OS X or your computer's firmware.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If there is a box marked Discoverable and it's checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it (not applicable to OS X 10.9 or later.)
Step 4
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Unable to connect to home wireless network with my iPod touch

I've had my iTouch for several months now and I'm still not able to connect to my wireless network at home. I've tried the resets and other suggestions I've found in the discussion groups but nothing has worked.
I have an older Netgear Router MR814v2 and it is unsecured. It is attached to my old desktop, HP Pavilion running Windows ME, which is not able to run the itunes software. My HP laptop is where my iTouch and iTunes software is installed.
The iTouch displays my network with good signal strength, but when I try to connect I get the "unable to join the network "NETGEAR".
Going to my router, it does not recognize my iTouch as an attached device. Why is that and what am I missing?
Thank you for all suggestions and your help.

I tried powering down the router. When it's off the iTouch does not recognize the network and then when it's powered on again, the iTouch recognizes the network. Unlike the public wi-fi spots that my iTouch responds to, where all the info like IP Address, Subnet Mask, Router, DNS etc are populated in the settings...my iTouch does not populate these fields at home even though it recognizes the network. I still get the unable to connect to network error. Could it be that my router is antiquated and can not support the iTouch? Like I said earlier, my Router does not recognize the iTouch as being attached to it.

First time MacBook user can't connect to a wireless network

Just got my first mac (mbpro 15) yesterday and can't seem to connect to my wireless network. I can see my network but when I select it, it doesn't connect. Do I have to do anything with my router since this is my first mac? The connection for my airport is showing as an amber color. What can I do to connect my cmputer to the Internet? Thanks

I just got done dealing with this. It took me 2 days and after 5 hours on the phone with Apple and Belkin they could not help me. I found out what to do after reading the forms. Try turning off the security on your router first. Then reset the router. Open the MacBook network preferences go to advanced setting for the airport. Delete your network connection. Now turn off your airport then turn it back on. Find your network again and connect now that the security if off. When this is done restart your MacBook. You should be able to connect now. This worked for me. I did not want to keep my network open so I then added the WPA2 security if you have it or use WPA pick a password and then start the process again. Reset the router. Open the MacBook network preferences go to advanced setting for the airport. Delete your network connection. Now turn off your airport then turn it back on. Find your network again and connect putting in the password this time. Now restart the MacBook and with some luck you should be good to go. I was ready to throw my MacBook out a window before I figured this out. Please let me know if you need more details than this. Good luck.

IPhone 5 won't connect to home wireless network

After updating to iOS 7 my iPhone 5 has been unable to connect to the wireless network in my home. It will recognize it, ask me to input password, and then it will say it cannot connect. I have shut the iPhone 5 on/off, turned on/off the wireless, turned on/off the bluetooth, and attempted to install the latest iOS update (but cannot because it won't let me unless I am connected to wifi).
I am having this problem with my MacBook Pro as well.

There is something wrong with your wireless router or network - especially if you have no problem connecting your iPhone and MPB with any other wi-fi network besides your own.
Have you tried resetting your wireless router and network in conjunction with the modem, and/or have you checked the manufacturer's website to see if there is a firmware update available for your wireless router model that has not been installed?
What type of encryption are you using with your wireless network - WEP, or WPA2?

Can't connect to any wireless network after waking from sleep

I have a Netgear wgr814 wireless router and a Powerbook 12" 867mhz. A few months ago, every once in a while when the PB awoke from sleep, it would not be able to connect to any wireless networks. My network showed in the airport menu, but the computer would not connect to it. I believe that the network settings show a self assigned IP of 169.x.x.x. Usually I can see 4 networks in the airport menu, but when it gets in this state only mine shows. Nothing I did on the computer side could make the computer reconnect: renew dhcp, restart, reseat airport card, etc.
After trial and error I found that if I restarted my router, the pb would reconnect and all would be well. The problem occurred about once a week for a while. Since resetting the router fixed the problem I thought that it may be my router so I updated the firmware. After doing so, the problem didn't occur for about a month, but now it happens at least once per day. Resetting the router always fixes the problem. I don't have to do anything to the PB. Once the router comes back up the PB obtains its IP and is happy again.
I'll mention that a Dell Laptop on the same network never has any issues and when the PB loses connection the Dell is always fine.
What could be doing this? My PB is over 3 years old, so is the airport card starting to die? That's the only thing I can think of.

hi there
alright.... I tried a bunch of things and I'm not exctly sure what I did that did the trick, but I got the problem solved. I turned off the WPA encryption on the AP. Then I turned it back on with a different password.
I wonder if the first password I had was too short and that was some how causing confusion.
