Airport/ wifi issue

Usually when I logged onto my macbook the wifi would automatically log on, but today it started asking me what network I wanted to log onto, It says: none of your preferred networks are available... select the network you want ot join from the list. So I opened the system preferences, checked my prefered list, and my network is the first one on that list. Next I used the assistant but that didn't work either. I know its not a big deal but it's so annoying to keep hitting my network, especially b/c it shuts off sum times so I feel like that stupid lil screan is constantly popping up. I don't know what to do so PLEASE help me.

System Preferences > Network > Advanced > Airport. Select all the networks on the list and click the minus. Then turn off then turn back on the airport.

HT202663 Airport WiFi issues with united_club

Hello,
I'm trying to figure out why I can't connect to "united_club" wifi properly. I get an IP address via DHCP, however, I can't ping the gateway nor the public DNS.
If I switch over to my Verizon MiFi, I can successfully connect the the internet. After removing the "WiFi" system setting completely and messing around with the underlying config files, as mentioned in some posts, I was able to connect. Now that I'm back in the lounge, nothing works.
This is very strange. Any thought on how to fix this?
I'm running McAfee Endpoint Protection for Mac, but did not install the desktop firewall.
Appreciate any hints to get this fixed.
Regards, V.

Hey there Fr3ddy,
It sounds like you are having trouble accessing a specific Wi-Fi network. I would use the Network Diagnostics to help you resolve or isolate the issue here. This section of the Yosemite Help menu should help you get that done:
Use Network Diagnostics - Mac Help
Use Network Diagnostics
Use Network Diagnostics to help solve Internet connection problems. If you can’t connect to the Internet, Network Diagnostics opens and walks you through solving the problem.
Use Network Diagnostics to diagnose problems related to your Ethernet, AirPort, or internal or external modem connections. If you are trying to connect to the Internet using another method, see the documentation that came with your Internet account.
If Network Diagnostics can’t resolve the problem, there may be problems with the ISP you are trying to connect to, with an external device you are using to connect to your ISP, or with the server you are trying to access.
If your Internet connection is working properly, but you are trying to connect to the Internet using a different network port configuration, use Network Diagnostics to investigate your network settings.
Choose Apple menu > System Preferences, then click Network.
Click “Assist me,” click Diagnostics, then follow the onscreen instructions.
Thank you for using Apple Support Communities.
All the very best,
Sterling

Spinning Beach Ball when turning off Airport WiFi. SL Issues, many! Help!

I performed a clean installation of Snow Leopard on my new 13 inch late 2009 MBP on release date. All of a sudden, I am getting the infamous spinning beach ball when attempting to disable my Airport wifi. It's so bad, that I am not able to gracefully restart my system. Seriously this is getting out of hand. Snow Leopard was supposed to make Leopard even more stable.
Steps I have taken, not in any particular order.
Verified and repaired permissions.
Ran HW test, no issues found
Reset PRAM
Deleted wifi related plist files from /lib/prefs/sysconfig and rebooted;
The only thing I can think of next is to perform and Archive and Install or....
...As much as I would hate to go back, Install Leopard.
I would appreciate feedback or suggestions as what to do. Looks like 10.6.1 may be worth waiting for. Oh how I miss Tiger.

HI,
If you use an Airport Base Station or Airport Express, try resetting.
If that doesn't help...
Boot from the 10.6 disk and verify the startup disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
Check available disk space.
Control or right click the MacintoshHD icon on your Desktop. Click "Get Info". Under the General tab you will see Capacity and Available. Make sure there is at least 10% available disk space, 15% is better.
If necessary, do an Archive an Install. It's the only install option available for Snow Leopard.

Airport 802.11g and WIFI issues with Apple bluetooth keyboard

Hey guys, this thing start to drive me crazy, I bought a Apple BT keyboard but just recently I started to having problems with my wifi connection and apparently I think this is due to the BT keys.
I started to notice this issue when I moving with the laptop in another room where usually I had maximum Airport signal, now it's happening that the signal start to lose power and when is just to the minimum, internet or other net staff don't work anymore and after 5 minutes of this apparently "freeze" wifi status, the airport loose definitely the signal.
After that I need to turn off the Airport card, most of the time work but sometimes i need to turn off two times to get it works.
After I read different blogs and forum, I tried to change channel, use the interference robustness, anything, and at the ending I reinstalled Leo, still have this problem, so I started to turn off the bluetooth connection and it look's like when the signal start to lose power the network keep working, and than reprise the maximum power.
So I can really fix this issue or is another "well done" by Apple? It look's like the Apple industry getting so close to the trash world! I'm sorry for these last words but my disappointed in Apple getting bigger.
Thank you for anyone helps.
P.S. a friend of mine with a Macbook Pro, Snow Leopard and my same Airport Base station have the same issue.

GuyI just fixed for now the problem turning off the bluetooth keyboard when I have wifi issues, it's the only solutions!

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:
Wi-Fi: How to troubleshoot Wi-Fi connectivity

Apple Support: About Wireless Diagnostics
http://support.apple.com/kb/HT5606

It may also be worth doing a search for the specific model number of your router to see if anyone has noted any issues with Mavericks.

Yoga 11S WiFi issues

Hi all,
As with many I am experiencing severe Wifi issues with new Yoga 11s. I will try to explain in detail in the hope that someone who better understands how wifi really works might be able to help diagnose.
I have a Talktalk badged Huawei HG533 router. This delivers c.15Mbs reliably all around my house (2xTVs, computers up and downstairs, 2xphones). Using Speedtest.net to capture speeds.
With the Yoga, if I sit right next to the router (as I am now), I get 15Mbs. In other parts of the house I get just 0.5Mb, including rooms where other devices are measured at 15. I have updated drivers and upgraded to W8.1 though I experienced exactly the same problem before the upgrade.
I have tested every room and it seems that it will either work at very close to the maximum (in a few rooms) or drops off catastrophically to 0.5mb or less. There is no in between. I never lose connection altogether. There seems no correalation between the level of signal displayed (4 or 5 bars) and the speed.The 'good' rooms are separated by fewer walls.
I have also observed that on occasion having tested in a good room and then moving to one of the bad rooms it initially shows good performance, before seemingly recognising where it is and throttling back to unusable.
It is as though once it gets to a certain distance/separation/signal strength it somehow 'jams' the signal.
I really neeed to find a solution to this as 1. my office is one of the bad rooms and 2. I am often in hotels, airports etc and need reliable internet even in poor signal areas. Any help much appreciated.

Hey everyone, I just registered here and I couldn't find a solution. Apologies if this has been covered already.
I received the Yoga 11s i5 as part of an internship and after keeping the package under wraps for a month or two, I decided to give it a go and start using it instead of my Microsoft Surface. Everything works smooth and I love it to bits - except for the WiFi.
I was able to connect a few times, but for the most part it just doesn't work. The WiFi icon in the bottom right corner displays the adapter icon with a little red x, and the Windows troubleshooter is unable to find a solution. I'm really not sure what the problem is because, so far, my connectivity problem is entirely random - several times, I was able to connect and use the WiFi regularly only to be greeted with the same problem next time I start using the computer. The troubleshooter once displayed an error message amongst the lines of "The network adapter is experiencing hardware/software difficulties".
I don't know if it is worth mentioning that I live on a college campus with a dodgy wifi connection, but every other device I ever used is working properly. Any suggestions? Only thing I did try so far is refreshing the system and reinstalling Windows but, to no avail.
Thanks in advance!

Mac mini wifi issues

Had my Ipad mini for about a week. At first, the internet connection over my Airport/time capsule( which I bought a couple months ago, so it should be the newest generation) appeared to be fine although, I noticed that the signal bar was always a single to double bar (if that's how it is called). Now, from time to time it even fails to connect.
I am now in my living room in front of my mac mini set, which is itself connected to the internet over Airport/time capsule. The Airport is about 20 meters (abt 65 ft) away. The Wifi signal of my mac mini shows full capacity. My Ipad mini signal bar...it just says" iPad". While (when) connected I also have issues with iPad's ITune Wi-Fi sync. Connected by cable, checked the sync over wifi, removed the cable and Ipad disappeared from the Itune screen. I reset the Ipad, connected and did the whole procedure with Itunes and the iPad icon sticked to the itunes screen for a while but after about an hour disappeared again.
Now the ipad won't even connect.
When this thing works, it is a wonderful item. When it doesn't, it is a source of frustration. Can anyone help to solve this connection problem (resetting won't work) ?
thank you.

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

Yosemite 10.10.1 update did not fix my wifi issue, did it fix yours??

The discussion about wifi issues is nothing new since Yosemite came out. Today I installed the latest update (10.10.1) which was to help with wifi issues such as your wifi dropping. I have tried every remedy that has been posted and nothing has worked. I constantly have to re-connect to my wifi network while on my computer. I guess I will sit patiently until this is resolved. I was excited to see the new update but after downloading and installing it, I see that nothing has changed. I have an iMac (2013) and have never had internet issues until I installed Yosemite. I hope the update helps you but it didn't help me.

Hi everyone,
I am trying to create a secure network on my MB air with OS X Yosemite?
Any ideas?
In the pervious OS version when you create a network on from the WIFI icon on the top of the desktop, there are
1) network name
2) channel
3) type of password
4) key in password.
Now with OS X yosemite, there is only
1) network name
2) channel
When the network is created there is not IP.
I am trying to use "airserver" a third party app to help project my iPad air to my MB air.
I am trying to do this when I am conducting the class and I would like to record my lesson.
Please advise.
My way of getting around this is to use Airport Express and create my own network that link MB air and iPad air.
But i do not want to look like a gadget guys and bring so many hardware to class... haha...
Hope someone have an alternative.
Cheers,
Andy

iPhone WiFi issue. I enter a password, click join, and get a message back that it is an incorrect password. I have several computers and other iPhones connected using the same password. Any ideas?

Hey there Gordo456,
It sounds like you are not able to join your Wi-Fi network with the correct password on 1 out of many devices. I recommend the troubleshooting from the article named:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/TS1398
Restart your iOS device.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
If that troubleshooting does not resolve the issue, I would next try these steps from further down the article:
Unable to connect to a Wi-Fi network
Verify that you're attempting to connect to your desired Wi-Fi network.
Make sure you're entering your Wi-Fi password correctly. Passwords may be case sensitive and may contain numbers or special characters.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings.
Thank you for using Apple Support Communities.
Regards,
Sterling

Can't access Time Machine settings when AirPort (WiFi) is on.

Problem:
My iMac (2.66 MHz Inter Core Duo) with 10.5.8 needs an upgrade to Maverick...it is connected to my home network with AirPort
I have a NAS on my home network (Verbatim MediaShare 2TB) wired connected, which I have had working as a drive for TM-backups. It stopped working with TM about 1,5 year ago, did never figure out why, backups just failed.
Now I want to get it going again for a fresh backup prior to the OS upgrade.
The issue I am facing now is that I cant access the settings for the backup drive in TM settings as the AirPort is on.
I need AirPort on to be able to mount the drive of the NAS, but then I cant access TM-settings. If I switch of AirPort temporarly to access TM-settings the drive which I need to select is dismounted.
I am kind of stuck. Why is this happening?

Lost connection to internet via 'airport' WiFi and 'NETGEAR WNR2000v' base router

After trying to connect 'MacBook Pro SnowLeopard' via Fire Wire '6pin to 9pin' to new 'iMac-LION' there is no possibility anymore to get contact to the internet, even all Network 'airport' configuration and passwords has been still the same. The 'NETGEAR router' configuration and activity was reset and checked successfully many times. Windows XP through 'Internet Explorer' by Ethernet cable via 'NETGEAR router' still works perfect. But 'airport WiFi' of both Mac's are screwed up suddenly completly after working perfect for more than 1/2 year! Need some help to get it working again!

IPad2 has wifi issues where others have not

Hi there, I have an iPad 2 that works fine on my wifi network. However, it's behaving different than my iPhone 4. I have 3 Airports Extreme in the house and 1 of them is dying, meaning it drops off the network every few days. A restart brings it back into the network. With 1 Airport down and 2 up, the iPad 2 can't connect to the network where the iPhone 4 has no problem connecting. All Airports have the same list of accepted clients. Out of curiosity: is the wifi architecture of the iPhone 4 superior to the iPad 2? I know, a new Airport will fix this but as I said, I'd like to know if there's difference. Thanks.

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.

Whenever I log in to mum's airport wifi (it has wep) after a few hours it won't work and says connection timed out. The wifi and airport also is invisible to mum's macbook ***?

whenever I log in to mum's airport wifi either with my iphone or macbook pro (her aiport express uses wep security) after a few hours it won't work and says connection timed out. The wifi and airport also is invisible to mum's macbook which means she can't login. If I plug her computer or mine direct into her virgin modem - it does work... I can't even find her express in airport utility to reset it any ideas what is going wrong?

Effective, but expensive solution to Wifi Issue

Until, yesterday my wifi signal would fluctuate when I left the floor on which my Apple Extreme router is located and went to the downstairs area of my 1500 square foot house. None of my other devices-- iPhone, MacBook, or iPod Touch- experienced the same issue. So, it became clear to me that, while the signal emitted by my router was sufficient to maintain a strong signal on my other devices, the signal was insufficient for the iPad. To remedy the issue, I purchased an Airport Express to extend my network downstairs. I have not had any issues with fluctuation in 24 hrs.
Unfortunately, this is an expensive fix, costing me $100 above what I had anticipated paying for the iPad. I don't know what the fix employed says about the iPad; I simply am not qualified to say. But I do know that the outcome has been bitter sweet. On the one hand, I am happy to have removed a distraction that prevented me from enjoying this wonderful device. On the other hand, my pockets are significantly lighter, and I am not sure I am comfortable having paid several hundred dollars for a device that is deficient in a way critical to it's use.

Well since princeton univ is dealing with ipad issues i hope that apple releases a patch soon.
But when patches are release for wifi issues usually people see the problem fix but reduced network speeds.
Just means they need to throughly test.... I should read up on apple the company and check and see if they are a iso90001 blah blah company which just means they adhere to certain principle industry standards.

IOS 8 WIFI ISSUES 5ghz airplay related! the real workaround here

Ever since upgrading to IOS 8, including IOS 8.01, 8.02 and 8.1 I had the wellknown Wifi issue. wifi speeds dropping from 120mbps to about 2mbps @ 5ghz in within a minute after connecting to the wifinetwork. often i couldn't even surf at all. but the wifi signal was always strong. With every update i was hoping for a solution from Apple but it never came. Tried everything that can be found on the internet. Resetting the network settings. Disabling "wifi networking" under Settings > Privacy > Location Services > System Services. Reinstalling my Ipad from scratch Used different routers and different setups. Automatic ip's and fixed ip's and different dns servers just to be sure. Nothing worked. The only workaround is switching to a 2.4Ghz network. So i was doing some tests and found THE solution, but i don't like it all. One of the biggest changes in IOS 8 is the ability to use airplay without a network. by using a wifi connection in combination with bluetooth. And here lies the problem. I disconnected al my Airplaydevices from my network. Denon AV-amplifier AVR2113, Pioneer wireless speaker XW SMA3 and an airport express. Et voila... My Ipad is back to normal. fast... no very fast internet connection and stable as ****. Just like iOS 7 was. Working with it for a couple of hours now without any trouble at all. But do i connect one Airplay device to the network the wifi is not stable anymore and extremely slow again on my ipad air. My Macbook running mac os x mavericks doesn't have these issues, neither does my iphone 5S. and they are also on the same 5ghz network. So I can create and recreate the issue and create a work around... Apple please come with a solution that makes me able to use airplay an ipad (on ios8) on a 5ghz network! like in iOS 7!!!!

I'm just going to throw something different into the mix. Could it just be that different Wi-Fi networks may use different ISPs and each ISP will have it's own configuration settings?
For example, if you have an iPhone on Cellular Network 1 and send an email, it'll use the SMTP server for that network. If you're using your home Wi-Fi you'll have the SMTP server for your ISP in your iPhone's settings, and that's what your iPhone will use when sending an email from home. But if you're accessing a different Wi-Fi network somewhere and it's using a different ISP, then it'll have a different SMTP server. So, sending an email for example won't work unless you turn off Wi-Fi and force your iPhone to use your Cellular Network instead (because it'll have the SMTP server for that network).
Now, the example above is specific to email, but I'm just trying to think outside the square a little compared to the other responses here.
Hope this helps you progress to a solution.
Joe.
