IMac PPC :: Since Installing Lion I Keep Losing Internet Connection
Mar 27, 2012
When I try to get email or go on the internet in general after being away for a short while, the internet is not connected and has trouble connecting. I have DSL and should always be connected. I also have a laptop (non Apple running Ubuntu) and there is no problem there.
Info:iMac (21.5-inch Late 2009), Mac OS X (10.7.3)
My mac is set to automatically connect to the internet, but since downloading Mac Lion 10.7.3, I'm having problems. I have to reconnect to the internet repeatedly throughout the day. I also recently updated Microsoft office - not sure if that's somehow related.
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.
Got my iMac back in the end of February and it's been working flawlessly. About a month ago though, my connection started randomly dropping after periods of moderate internet-use. Say maybe, 20-30mins of browsing. It usually starts working fine after I shut the computer off for a while and try again. I thought maybe it was the ethernet cable, so I got another one, but with the same result. So it got me thinking, maybe it is my ISP. Called Verizon up and they said everything looked good on their end and that my IP was showing up fine. They reset my connection, but with no result. The gentleman on the phone suggested it maybe the computer.
I took my Dell laptop and tried surfing using the built-in Wifi for a while. 2 hours later...working fine. So I tried pluging the ethernet cable to the laptop, worked fine again. So now i'm thinking it HAS to be the computer. So switched the built-in Airport Wifi on the iMac on and tried it out. 2 1/2 hours later...everything works great. WHAT THE HELL!? I'm thinking, since it just suddenly happened, the problem must've been triggered by some sort of update I did(which I don't remember if I did). I searched the Apple Support forums and it turns out, several people have had the same/similar problem with their Macs with no solution.............
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'.¬†¬†
Ever since I upgraded to Lion, my imac loses its wifi connection when it sleeps.When i wake it up i have to always go up to the wifi icon on top right of screen and wait till it sees my network and then say connect.This never happened in snow leopard, seemed to stay connected.†
Any else having a problem with periodically losing their network connection on their new iMac? Basically not working properly with your router?
I've narrowed the problem down to the router by connecting directly to the modem and using PPPoe, which works fine.
I had a dlink router which I thought was causing this. Whenever I would use the new iMac I would lose the internet periodically (on my whole network). It would take about 5 minutes to return.
I bought a new linksys router WRT120N to replace the dlink and the problems continue but the internet now only goes out long enough to disconnect my instant messengers and interrupt my streams. Just a little blip. I updated the firmware on the router which I thought worked (ran flawlessly for two days) but now the problem is back.
I'm just wondering if I'm the only one suffering from this or has it been happening to others. It's rather annoying.
I'm running 10.7.3 on my Mac Pro4,1 and have the standard Apple USB keyboard attached while using the Apple BT trackpad.¬† After sleep and/or log off, I am often not able to use the keyboard any longer.¬† To revive it, I must restart my system.
I have no idea what's wrong. I tried reinstalling os x with no luck. 21.5" 3.06GHz 4GB ram 500GB hd iChat keeps disconnecting, pages and youtube vids load extremely slow(about 1min to load this post page).
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.
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?¬†

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.
Trying to get Mac to connect to the internet video D-Link router. When I click on my wireless the box that comes up shows a place to enter a password and I do so but the connect button is not active only the cancel button is active? Did find another box that gives about 6 choices of connection types this is geek to me. In the list of wireless connections there is one unsecured and it does connect to it.
I have two identical iMacs hooked up to a router. Both had no internet connection problems until now. One iMac works fine, the other just stopped. I swapped LAN cables and router ports but the iMac that quit connecting still won't connect.
I am relatively new to the Mac world, and so please excuse me if this sounds like a dumb question.¬† I have a iMac running 10.6.8 and hard wired, not wireless.I recently purchased a MAB with the intention of NOT hooking it to the internet but just stand alone, for writing purposes. I needed an app for it, so¬† I purchased it through the app store on the iMac with the intent of transferring to the MAB via flash drive. Now in retrospect, its probably not the way its supposed to happen, due to licence rules, etc.¬† how I can get the app on my MAB or will I have to get it online to do a transfer from the iMac?¬†

I recently bought a 27'' iMac (3.2 GHz Intel Core i3, OSX10.6.4) and all was fine and dandy until yesterday when my internet connection suddenly got very slow. It takes forever to load pages, if they load at all. The rest of the iMac is fine as before, which leads me to conclude this is an internet issue. I cleared the cache and browsing history in Google Chrome and no improvement. I tried using Safari and Firefox and they were slow too.
I also have a MacBookPro (2.2 GHz Intel Core 2 Duo, OSX10.6.4), so I checked the internet speed on that and it was normal. Both MBP and iMac are connected via an Airport Express. I searched various forums and threads for a solution, but I know very little when it come to these things so I quickly got stuck in technical jargon. I've tried to change the DNS server settings (first to 184.108.40.206 and 220.127.116.11, then to 18.104.22.168 and 22.214.171.124) but this has not helped.
why does my imac lose internet connection after coming out of sleep mode and sometimes from power up. This is something that started about ten weeks ago.I have been all though road runner's diagnostics and etc. So now they insist that its with my imac.
I just installed Lion to my Mac (Mac OS X Lion 10.7.3), and somehow I now seem to have trouble accessing internet. I use Wi-fi, and the actual connection with our internet-provider works just fine (we have other computers in the house, and have not experienced any trouble with them). When I want to use internet I have to go to the network panel, click on "help me", and run a diagnostics. After that, I have no problem assessing internet.¬†
I have an iMac 2.7 i5, 8GB, OS X Lion 10.7.3.¬† I purchased this iMac just about 3 weeks ago and from the beginning experienced regular dropping of the internet connection. I have cleared all other networks that appeared in the Preferred Network window other than my own.¬†I have also unchecked the "Remember what other networks this computer has joined" box just in case I needed to. No luck. I am using an ATT 2Wire wireless router that's just over a year old but I haven't experienced the connection drop problem with an older Macbook (about 4 years old) that I also own.
I know this has been a wifi issue for many, but this is occurring with ethernet as well on our iMac 2.93. Only began with Lion update. All other 5 Macs (Snow Lep/Lep/Tiger) and several PC's on network have no problem. Have set iMac's internet connections to static/manual ip. Worked for a few days, then back to dropping. This is obviously an OS issue.
