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).Â
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'. Â

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.

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.............

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.

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.

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.

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.

I got my Kindle 3 today (yes I bought one over the ipad simply due to the price) and Ive spent some time trying to connect it to my imacs airport wi-fi. I have tried Customer service over at Amazon but sadly, no reply as of yet. It seems that the Kindle wont connect to "enterprise or peer-to-peer networks". So everytime, I enable sharing and my network shows up - it either wont accept the password or it tells me that "Kindle does not currently connect to enterprise or peer-to-peer networks"

On startup the WiFi connection symbol initially is full and black and then goes grey with in a few seconds. If I click the WiFi symbol the drop down menu shows my WiFi network which I click put in WEP code but then I get a message after a few seconds that the connection has timed out. All other Macs in the house connect to the WiFi fine.

My Linksys WRT610N with the latest firmware worked fantastically on multiple Windows 7-based ThinkPad. However, three (3) different iMac's have had the very same problem of dropping the connection and of my having to powercycle both my cable modem and the W610 router for it to work again at all! Once it drops the active connection, that's it. I have tried a few different settings and nothing has made a difference.
Can you maybe help point me in the right direction or should I just ditch it for an AirPort Extreme or Time Capsule? One additional point: It works worst in the 5GHz frequency band, even though there are none in my neighborhood, and if there are, they have their SSID's (network name) hidden. The 2.4GHz band is extremely crowded where I am which makes it difficult to enjoy my WiFi connection.

I have a I mac and an airport. I've been having problems lately(one month) every time I try to connect to the net. it says there is no connection. if I refresh, it works. the reception icon was showing full (4 bars). 3 days ago, no reception, o bars, today, I got it back. i am about 50 feet away, around a corner outer house wall. nothing has changed in terms of new or moved electronic equipment. I even turned off my 5.0 ghz phone.
any thought on how to fix this?

Since installing Lion I lose my wireless internet connection frequently - only from the IMAC, not from the IPAD or Dell. I called support and after quite a lengthy "try this" session, I was told that this was a known problem. I can always get it back but sometimes have to unplug the router.

For the last 2 weeks my wifi connection has been playing up. I use Wifi and my iMac connects directly to my router and it works slow if at all as some pages don't load. I can get by but its frustrating using it and this problem is specific to my iMac as every other device using Wifi works fine. These devices, that work fine, include mobile phones and a MacBook Pro.Â
I'm using Chrome and its the same with other browsers. I usually get a "resolving host' message in the taskbar when loading pages. Sometimes pages do not load at all or they are slow to load and at times some elements like images don't appear. My OS X is 10.9.4.Â

I recently switched cable providers to Time Warner. They set up a Ubee cable modem and all devices (IPhone, IPad, AppleTV, etc) are all connecting to the wireless network except my IMac.  I tried renewing my DHCP lease, updating to OS X Maverick but every time I try and connect I get an error message that says "Connection Time Out".Â

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?

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?

I have a small network running from a Netgear Wireless Router. It's set to be the DHCP server. Then I have 2 MAC's connecting wirelessly to this router. Both set to receive IP's from Router. also, Windows XP SP3 Desktop, set with Static IP address and via LAN. On the Windows XP machine, I have a shared folder directly under C:. Shared name is BOAW. Connection to this server is perfect, but at times it will start dropping. Both MAC's will randomly get this message saying that it lost connection to the <<Specified Folder Name>>.
It doesn't loose connection at specific times or timeouts. It's will work good for a day or so, then will start dropping and the dropping seems so warm up and multiply. Only way to get this connection back, is to restart the Windows XP SP3 machine, which is the the PC with the shared folder. Sometimes it helps if you switch off / on on the Airports from the MAC's, but that stops working after a few goes. PC restart is the only way so far. Before, the Windows Xp SP3 PC, was running with wireless as well, and I first thought if I change over the LAN interface, it would help with a more stable / faster connection.

I am running into a headache with my wireless network connections. When I close my laptop to put it to sleep, I often lose my network connection. It is easy enough to reconnect; I simply try to connect to a web page, get network diagnostics, and re-enter my password (and click on the "remember password" box). All works great -- until I next close the laptop. It happens all the time at one site, sometimes at home (using Time Capsule), and seldom at the church where I volunteer.
I have checked all my settings and can't figure out what's going on. If my poor memory is correct, I didn't use to have this problem, but it has been going on for the last couple of months. I know I could keep the sucker open, but I want to save power by putting it to sleep -- and the desk where I work at home has a sliding drawer so it has to be closed to close the drawer. (And my network connections are all in the desk also.) I've posted this question to the Apple forum but haven't gotten any replies there other than a couple of followup questions. I am using Time Capsule as my router and I have updated the software
