MacBook wont join existing WiFi network??

My MacBook wont join an existing, working WiFi network - I keep getting "timeout" errors even though I am entering the correct WPA - can anybody please help me figure out why??
thank you

First contact your ISP. You need to confirm that the issue is not on their end.
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

How to set up TimeCapsule (4th) to create own private (wired) network behind Airport Express (5th) that is set up to join existing wifi-network of fritz adsl modem/router?

I work in an office building with free Wifi to connect to the Internet. I want to be able to use this internetconnection, but at the same time I want to shield of my own wired network.
I've made the following configuration:
- fritz adsl modem / router
- Airport Extreme (5th gen) set up to join existing wireless network (green light, works)
- Lan-cable from lan-port AE to wan-port TC (4th gen)
- Lan-cable from TC to Mac
- Lan-cable from TC to Printer
When I set my TC (network-settings) in bridge-mode everything works fine, but my Mac and Printer get an IP-address from the fritz modem / router and are visible to others.
I tried to set TC in NAT/DHCP-mode, but then I get the error message that I should set a static IP-adress for TC. When I set TC in DHCP-mode, it looses connection to the AE. I'm not sure what to do now. Does anyone know how to set up my TC and create my own private network and still be able to get on the internet?

You are using free internet.. so there is a price to pay.. that is convenience and non-ideal network setup.
The better alternative is to pay for your own connection. Then you are completely free of the possibility of others in the bullding seeing your connection. (as long as you secure the wireless).
But I think you are probably over worrying about public wifi.. if it is setup right.. ask the building admins.. it should be setup so each user cannot see another users connection. This is typical for most wifi setup and simply means you can see internet connection but nobody else on the connection. ie other wireless users.
Having a router with NAT makes it then more secure again and allows clients on your own network to interact with each other. But you can setup wireless to the free wifi for every client.. (depending on how many IP you are allowed).. and run a secondary network without internet access. This is easy for desktop etc where you have a wireless and a wired connection but less convenient for mobile devices.. unless you use a cloud connection and each client can link and share via that.
Have I made the explanation worse??
Think of it this way.. if you had 3 laptops.. all 3 could connect to the internet from the building wifi.. but they cannot talk to each other or share resources in local office. You can put resources out in the cloud, that can be shared.. but that adds traffic and most free services are not fast.
Now you can also plug all three into Time Capsule by ethernet.. and share local resources. Files, printers backup etc. This network is not connected to the internet at all. Each laptop has internet via free wifi and local connection.
For devices like iphones that have no ethernet or other method.. you could use local wireless and public wireless.. but in turns.. still the only advantage is less issues with double NAT.. if that causes problems.. then this is an alternative.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

Cannot add AirPort TC to existing wifi network

Tried severla times to add APTC 3 TB (newest release) into existing wifi network using either iPhone or MacBook Air AirPort Utility. It does not work, as I receive an error message "An unexpected error occured. Try again"

It is difficult if you try and do setups Apple does not support.
Connecting to existing wifi network is not supported. You can do it but it is the worst possible setup and definitely to be avoided.
Is it not possible for you to connect to ethernet on a modem or router?
If you must here are instructions to setup "Join a wireless network"
https://discussions.apple.com/thread/5719954?tstart=0
If you run into trouble .. take some screenshots and post them.
Be fully aware of what you are doing.. you are taking an expensive unit.. and making it a dumb client.. you lose all advantages of the new Gen5 TC.. you may as well have got a cheap Gen4 from the refurbished store.
No wireless AP and no ethernet ports.. and slow slow wireless double hop backups on whatever your existing wifi is.

How do I change system settings so that users are not required to enter the mac's admin pw in order to join a wifi network?

how do I change system settings so that users are not required to enter the mac's admin pw in order to join a wifi network?
Right now my macbook pro requires an admin password before connecting to a new wifi network. In other words when a user that is not an admin tries to connect to a new wifi network the pop up displays indicating that it is locked and an admin password is required.
Is there a way to remove this restriction so that a non admin can connect to wifi without the mac's admin password.

You can enable / disable this option in System Preferences:
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab > Require administrator authorization to: Change networks

My wife's i-pad 3 was just downloaded with iOS6 and we're unable to join our wifi network at home. Can anyone help?

My wife's i-pad 3 was just downloaded with the latest iOS6 and she's now unable to join our wifi network at home. Can anyone help?

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

HT201945 How do I use my time capsule on an existing WIFI network?

How do I use my Time Capsule on an existing WIFI network?

Use an Ethernet cable to connect from one of the LAN <--> ports on your existing wireless router to the WAN "O" port on the Time Capsule and then use the setup "wizard" on your Mac to configure the Time Capsule.
It will suggest that you set up the Time Capsule to create a new wireless network. If you don't want or need another wireless network, you can turn off the wireless function of the Time Capsule and use it as wired hard drive only.
Leave the Ethernet cable connected at all times. If you need to locate the Time Capsule in a different area, you can put it anywhere that the Ethernet cable will reach up to about 330 feet or 100 meters.
The only exception to using an Ethernet cable would be if your existing wireless network is provided by another Apple router. Then.....you would have the option to have the Time Capsule connect using wireless and extend the network, although using a wired connection would still be the better way to go in terms of performance.

How do I get a 1st generation time capsule to join a wifi network?

OK, I've searched the groups but no luck. Here's my situation;
I'd like to configure a 1st generation time capsule to join a wifi network ideally with a printer attached to the USB. My set up is an iMac running 10.9.3, Airport Utility 6.3.2 and a 1st Generation TC with the latest firmware (7.6.4). I'm trying to connect it to an ADSL Wifi Modem/Router. I know a cabled connection would give better performance but want a wifi only connection as the printer is in a different room.
I've disabled the network functions (bridge mode) but I can only see wireless options to Create a Wireless Network, Extend a Wireless Network or Off, not to Join. If I try to extend I get the option to add an SSID, security & passwords but it doesn't seem like parameters to join -the drop-down doesn't list available networks to join & manually entering the main wifi network and password doesn't work.
Is my desired config even possible?
Dave

Something.....a Mac or PC will need to have a 5.x version of AirPort Utility installed on the computer.
Perform a factory default reset on the Time Capsule by powering it off for a few minutes. Then, hold in the reset button first and keep holding for an additional 10-12 seconds while you simultaneously plug the power back into the Time Capsule. Release the reset button after the hold period and allow a full minute for the Time Capsule to restart to a slow, blinking amber light.
Open up AirPort Utility on the computer, select the Time Capsule and click Manual Setup
Click the Base Station tab below the row of icons to type in a device name and password that you want to use for the Time Capsule, set Time Zone, etc.
Click the Wireless tab next to the Base Station tab
Hold down the option or Alt key while you click on the Wireless Mode setting box
Select the Join a wireless network setting
Select the name of the wireless network
Enter the password for the wireless network
Verify the password
Click Update to save the settings
Note....everything here assumes that the router that provides the wireless network is using WPA2 Personal security, which is the default setting for the Time Capsule.

I reset my network settings, and when I went to join my wifi network i typed in the correct password, but it will not let me join. Other iphones and devices can however....

I updated my software to iOS6 and now my phone won't automatically join known wifi networks even though I have it on. It goes back to 3G every so often when I'm at home instead of using wifi, and each time I ask to join it asks for my wifi password

Try this for your home Wi-Fi:
On your iPhone, Settings > Wi-Fi > select your home network > "forget this network"
Power down (unplug) your wireless router
Restart your iPhone
Plug in your router
Re-join that network
I don't know if this simple technique will fix it for good but try it. There is a long thread about this problem here: iOS 6 WiFi Disabled

TC to extend existing wifi network

Hi there,
how can I use my TC to extend my existing wifi network (provided from a wireless N VDSL-2 router? I tried to put TC in bridge mode (extend wireless network) but got the reply "The network you selected can not be extended"...
Help please ! ;-)
Chris

Hi Bob,
My router is near the entrance door as it needs to be plugged in the telephone master socket there.
Initially, I placed a short ethernet cable between the router and the TC which was placed right next to the router. I set up the TC to create a seperate wifi network. The signal strength in the rooms furthest away was similarly weak/insufficient in the two wifi's.
Now, I plan to place a second unit half way. Unfortunately, due to local circumstances, this will need to be slightly nearer to the entrance hall than to the rooms furthest away. Hence the question which unit (Airport express or extreme base station) will provide the strongest signal?
In the new configuration I would plan to no longer use my old router; instead I would use the TC and a new unit...
Should I leave the TC near the entrance or place the TC in the middle of the house...
Many thanks for your help.

HT1695 unable to join any wifi network

I am unable to join any wifi networks. Wifi is on, but the dial next to "choosing network" keeps spinning!! I can't access any wifi.

iOS: Wi-Fi or Bluetooth settings grayed out or dim

Unable to join certain wifi networks

I have a 64GB 5S on iOS 8.1 and over the past several months I've noticed that I can't join some wifi networks. I have no problem with the type that prompt for a password, but if there's a browser window opened and I have to agree to terms (usually seen on store networks like Publix, Lowe's, etc.) the page just won't load. So I'm now completely unable to join these networks. I usually get an error message eventually about the request timing out. I don't have issues with any other unauthenticated or simple password-protected networks.
I've looked and I haven't seen anyone report quite this issue. I noticed it before the iOS 8 updates, so I don't think that's the culprit. I've tried turning the wifi off and on with no avail. I really hoping not to have to do a restore or anything like that on the off chance it will fix the issue, but at this point I'm open to suggestions.

I'm guessing these retail establishments require a login page to access their Wi-Fi? For ones that require a login, if it does not open automatically, opening a new tab in Safari has always created the prompt for me. You can try some troubleshooting, but it appears this has been going on for some time. You can try going to Settings>General>Reset>Reset Network settings and see if that helps. If not, then you can try a restore, or make an appointment at the Genius Bar of the nearest Apple Store to have the hardware checked.

It should connect properly with your iPad mini, but it requires an App. Also mentioned on Garmins' site.
