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'.¬†¬†
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.
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.

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.
So my 6 month old Unibody has had an issue for a while that it drops the internet connection, though keeping the network/WiFi connection. It started out just on campus where there is a campus wide SSID that is unencrypted, though requires a login to start browsing. A restart of the computer fixes this issue, though it always repeats itself (usually after 30-45 minutes of browsing, no downloading). Lately, the issue has been getting worse. It is now dropping the connection on other APs, and even stops the Airport card altogether (KisMac can't even scan). I had a backlight bleeding issue fixed by Apple. Is this connected? I know the airport card is in the screen, so maybe they didn't fix it well.
I'm looking for a solution to my WiFi internet connection.†I haven't used my MacBook Pro laptop in the last week or so - which means there is no way I have done any changes to the network configuration. However when I now try to connect to the internet via a Hub - which is previously set up on the macbook and worked no problem - is now not working at all.

There's something wrong with the Wifi connectivity on my Macbook Pro. Every few minutes, I lose connection to the internet even though it says I'm still connected to my network. I have to turn Wi-Fi off and then on for it to start working again. It only works for a few minutes and sometimes hours, but then I have to turn Wi-Fi off and then on agian. It only happens on my MacBook.
I use a 4G Galaxy Nexus to broadcast a private WPA2 network.¬† The 4G signal is always strong, and I've verified that the internet is active on the broadcasting device, and that other non-Apple devices maintain a solid connection.¬† However my macbook pro does not lose the network connection, the internet stops working only on the macbook pro and I must "turn Wifi Off" and back on using the top right menu icon in order for the internet connection to resume working on the laptop.¬†It will stop working every 5-10 minutes.
I have a first gene iMac g5 at work that does not have wifi. I found a USB wifi adapter on amazon for $15. If I use that, can i share my Internet connection over wifi just like i can with a built in airport card in my macbook pro?
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.
Recently just switched from 16mbps to 100mbps internet connection. Internet is connected tru Wifi and max speed i get is nothing more than 15mpbs and if connected through ethernet ill get speed more than 80mpbs. How to acheive 80-100mpbs tru Wifi? Called my service provider and reason given was that my network card doesnt support or its an old network card but my iMac is new
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...
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.

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.
Almost every time my laptop goes into sleep and back out I lose my wireless internet connection? It's not every time but it's getting more and more frequent. Is this a problem with my wireless router or a setting within? My 13" MBP is a June 2009 model. I have the Best Buy warranty but I can't be without my laptop while I'm on the road for work.
