OS X V10.7 Lion :: Wifi Losing Connection - How To Change System Config

Mar 14, 2012

Since upgrading to Lion I've had the problem with wi fi losing connection and this seems to be common?The Apple support talked me through a change in system config. I'm no expert and not sure if I could repeat if needed.The support desk could not guarantee that this will permanently fix the problem though.

IMac PPC :: G5 Keeps Losing Its WiFi Connection?

Jun 28, 2012

I have 3 macs working off my wireless router.  Two out of three are still working fine, but the third (an iMac G5) keeps losing its network connection and either won't find the network or, if it does, will not allow me to rejoin it, even after entering the relevant key/password. It has been in the same location in my house and has worked fine for the last five years.  But oddly, if I move the G5 to within a few feet of the router it starts working again (though sometimes seems unable to find the network, although when it does it will let me join it, hassle free). 

Have spoken to some Apple guys and, following their advice, have gone into SYSTEM PREFERENCES, NETWORK, LOCATION but having got that far a pop-up appears telling me that an application has changed my network settings.  Zapping OK, this dialog box just keeps re-appearing and the only way I can get out of this corner is by 'force quit'.

OS X V10.7 Lion :: Losing Internet Access For IMac - WiFi Icon Changing To Exclamation Mark

Jun 3, 2012

For several weeks I've lost internet connection on my iMac every day or so; the wifi icon changes to show a ! and is otherwise greyed out. My internet connection is via a relatively new Time Capsule (2011) which has an ethernet cable connecting it to my Sky broadband router. I moved to this new Sky broadband router in early Jan 2012 (changing to Sky as a Broadband provider) and it works nicely as a router. My iPhone, iPad, AppleTV and a range of other devices (including an Apple Airport Express connected to a Sky TV HD box to enable it to download movies) have continued to work on the internet without problems.

The IP address of the iMac (27 inch quad core i7, 8 GB RAM, fully up to date on Lion) disappears from the Network settings when the problem arises but the connection of the iMac to the wifi (and backing up to the Time Capsule) still works. I can even use a VNC app on the iPad to connect to the iMac on the same wifi LAN when the IP address has gone and the ! is showing in the wifi icon on the menu bar. To get reconnected to the internet, I just restarted the iMac and it was then back accessing the web nicely.Eventually the iMac would not connect to the internet at all. It would momentarily get an IP address from the router and then lose it again. I then tried taking the iMac to the Apple Store.

Various diagnostics run in store at Genius Bar and during the week and the problem (using the same account) was not replicated.On its return home, it was still not working on the internet.I then tried booting into 'safe mode'. This enabled a stable and reliable connection to the internet!After several days in this mode, I re-installed Lion and booted into normal mode again. The problem returned and has been with the iMac since. However, at least a restart of the iMac gets it straight back on to the internet again.I suspect some sort of corrupted network preference file or the like. But where?The disconnection from the internet can happen any time of day; for example it happened while typing this message but more often than not it happens when the computer is unattended.

MacBook Pro :: Airport On Brand New 13" - Wireless Connection Losing It's Connection

Jan 26, 2010

I recently purchased (as in days ago) a refurbished 13" Macbook Pro. I just noticed today that my wireless connection on my Macbook Pro has been losing it's connection about every other 2-3 minutes. I was on iChat with a buddy this morning, and I must have been disconnected and then reconnected about 8 times in 20 minutes. I first thought it must have been a problem with iChat. That said, I have sat here looking at my screen for the past ten minutes, and I have seen the Airport wireless indicator disconnect and then reconnect again at least three times in the past ten minutes.

I have AT&T U-Verse Service, and I am forced to use their provided 2WIRE router. That said, I have had no problems with any other device that uses the wireless connection, from my iPhone to my PS3. I work from home and have my HP laptop literally sitting right next to my Macbook, and it has not disconnected once from the same wireless connection, whereas my Macbook has literally disconnected at least 20 times.

OS X V10.7 Lion :: Force System To Use Second Connection Of Network Connection List For Internet Access?

Jul 5, 2012

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?

OS X V10.7 Lion :: Does Find Mac Require A WiFi Connection On The Target Mac

Apr 8, 2012

This weekend I upgraded my Macs to OSX Lion 10.7.3 and most everything is great. I spent some time trying to figure out why iCloud's Find My iPhone app will find my wife's MacBook Air and my iPhone 4 (iOS 5.1) but will not find my 2008 vintage MacBook Pro. I finally found one misconfigured AppleID and corrected that which then caused Find My Mac to report the MacBook Pro as "Offline" when it was clearly connected to the Internet (via Ethernet cable to my Time Capsule)  and even logged in to iCloud itself. On a whim, I turned on WiFi and that did it. The MacBook Pro is now found and its location reported. I have not found any caveats about the Find My Mac requiring WiFi.

Mac OS X Lion Server :: No Connection To The Internet With Ethernet, Only Over Wifi?

May 28, 2012

After switching to a new provider and getting a new dsl modem (a fritz!box fon 7390) I tried to setup my homenetwork again. Now the weird thing is: my Mac Mini running OSX Lion Server doesn't seem to be able to connect to the internet over its ethernet port, only when using a WiFi connection...When it's connected with ethernet it can reach the dsl modem without any problems, but it can't ping/telnet or anything else through, only over WiFi... As long as I use the mini servers WiFi connection everything works fine, but that doesn't make any sense to me.I've checked the servers setting and the Fritz!box settings and I can't seem to find anything obvious. Of course I could just go on and use the WiFi connection...

ps: all the other computers can connect fine using either wifi or regular lan connection... I even tried the exact same cable with another laptop just to make sure...

OS X V10.7 Lion :: Ethernet Internet Connection Fails But Not WiFi?

Jun 29, 2012

I am on a Mac Mini connected to the Net via a FON wireless router and Ethernet directly to my broadband modem. I have had problems with both the modem and an Airport Extreme, which eventually died, but I am back up again with the modem via the FON router.The odd thing is that I can't get Ethernet to work over a direct connection to the modem. Diagnostics tells me that the ISP and Internet fails. I can connect to the modem over Ethernet, however, change its settings etc. in my browser. There are solutions mentioned here involving changing the etc/authorization file, but wouldn't that also affect the WiFi if that was the problem? 

In short, Ethernet connection to modem works. WiFi connection to FON router and then to the ISP and Internet works. But the Ethernet configuration does't go that last bit, it only works locally. Using that route, I can't connect to the outside world. I have restarted the modem, the computer etc., but that should not be the problem as both works over WiFi, using the same settings for the modem. How do I best troubleshoot this? I am getting an AirPort Express, perhaps it will work better with the modem that the computer itself, but I doubt it.

OS X Mountain Lion :: WiFi Via 10.8.5 - Connection Timeout Occurred

Jun 1, 2014

I've had the same internet connection for 5 years.  Same wifi.  Same password. 

My previous mbp / os had no problems connecting and *staying* connected. 

Now, with my 8-month-old MBP / OS10.8.5, I regularly get bounced off wifi and when I try to reconnect, I see my wifi in the networks list, but I get "a connection timeout occurred" fail. 

Incidentally, my iPhones (4 and 5) over five years have *never* encountered this issue.  They are on the exact same wifi / password / network as my MBP.

OS X V10.7 Lion :: Internet Connection Cutting Out Regularly Despite Wifi Signal Being Strong

Apr 30, 2012

I am having internet connection issues with my MacBook Pro 2011 - running the latest version of Lion OSX. My connection cuts out regularly (every 10 - 15 minutes) despite having a full wifi signal. It is happening on two different routers, in two different locations with two different ISP's. 

When I run Network Diagnostics ISP is the test that fails, but after a couple of seconds diagnostics fixes it until the next 10 - 15 minutes. The only other alternative is turning wifi off and on. Both of these only last for the 10 - 15 minutes before it cuts out again. 

It is very frustrating and research online seems to indicate it is a Lion issue. I have made an appointment with a genius, but browsing online it appears there is no solution. It is not acceptable.

Hardware :: Switch Time Capsule To Wired Connection / Using Wifi Connection On Smartphone?

Feb 10, 2009

I have a Time Capsule wirelessly connected to my iMac. Since I've encountered some problems with backups because of intermittent wifi connection failures, I want to switch to a wired connection with an ethernet cable. I know I could fiddle with the wifi channels etc. but since the TC is just sitting next to my iMac anyway, I could profit from the higher bandwidth of a wired connection as well.Two questions:

1. What exactly do I have to do to make the switch? Are there any new settings I have to apply? Create a new network?

2. Will I still be able to use the wifi connection to get on the internet using my smartphone?

OS X :: Losing Wifi Settings In Keychain?

Dec 26, 2010

For some reason, approximately once a month, the Mac loses the wifi settings. This sends the clock back to January 1st and takes several attempts of reentering the network name and password before it is recognised again.

Also, the wifi settings seem to no longer be part of the keychain when that happens.

This is getting to be a pain. Does anyone know why this happens (it only happens on one of the Macs; others are fine)? What can I do to repair it for good?
