Intel Mac :: It Keeps Dropping And Instantly Resetting My Wifi Connection
Mar 28, 2012
Every 2-20 minutes, my iMac is dropping, then instantly resetting my wifi connection. The actual wifi drop lasts no longer than 5 seconds, and instantly reconnects itself with no input from me... the problem is it completely interrupts any downloading, streaming, gaming, or anything else I might be doing that requires a constant internet connection. It seems to drop off just long enough to stop the connection, then it resets all on it's own.
I'm currently using a mid-2011 27 inch iMac intel core i5 3.1 ghz processor w/ OS X Lion 10.7.3. I have a Linksys router and a GCI issued modem, unsure of the brand as there are minimal markings on it. The internet/tv service (run by GCI) is smooth throughout the rest of my home, and no other items we own connected to the net seem to have the same problem...
I have tried soft resets on both the modem and router. I have restarted my machine several times and re-added the network location and wifi connection to my computer. I have unplugged both modem and router to let those reset and have unplugged and reconnected my coax cable for several minutes as well. No time of day seems to work well, and it's becoming quite difficult to work and do other fun functions like stream television or game

I work for a business that sells a lot of computers, Macs specifically. We've got a wi-fi network in our building; however, the network constantly drops out. Despite our pleas to IT, they will not fix the issue. Our demo computers that customers can play with and consider purchasing often lose Internet access because of this. Whenever this happens, I have to manually turn the Airport off and then back on again, which will get it to reconnect. Does anybody know of a way to have the computer automatically do this every so often?

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.

It seems that every now and then my wifi will quit working. If I turn airport off and on it fixes it but I never had this problem in leopard.

My airport keeps dropping and it is wasting so much of my time. I have tried all the methods suggested online and none of the worked. I want to go back to snow leopard but I don't have my disc. And can I have my money back from Lion? I really will not use that until it is fixed.

My Lion OS 10.7.3 iMac just does not seem to be able to hold a stable connection with my home wifi network. After around ten minutes, sometimes more, sometimes less, usually when I've gotten up to do something else, the wifi is lost. It stays "connected" to the network (ie the wifi bars are black) but no internet comes through. Every time this happens, I turn WiFi off and reconnect and it fixes it every time, but it is still extremely inconvenient and troublesome to have to redo this constantly.

My iMac keeps dropping internet connection. This has only been a problem since installing Lion, it often tells me there is no connection when my iPhone and MacAir work perfectly so i know its not the broadband itself. I also get the message that my network configuration has changed.

I have an iMac (without an Airport Base). It is connected to a Sky router through an Ethernet cable but still with wireless capabilities. The internet connection keeps dropping out at regular intervals throughout the day to the point that my partner may just throw it out the window! The router lights still show it is connected as does the wifi signal at the top of the screen. Our iPhones still work even when the Mac drops off.

My iMac (purchased Feb 6) is constantly dropping the wifi signal. It seems to happen randomly...sometimes it's there, sometimes not and I must go to Networking icon and all the steps to reconnect!. (My iPad2 and IPhone are not having this problem...or perhaps their 3G has kept me from noticing.)

Since last week my iMac (Early 2009, OS 10.7.3) has been dropping its connection to the Internet. I'm using a router connected to an Airport Extreme and connect to it via WiFi. I tried connecting via Ethernet cable from modem to iMac but it would drop the connection entirely, which is why I had been connecting via WiFi. I have no problem with my other devices (iPad, iPhone and MacBook, this one with 10.7.2 installed), they connect immediately to the Internet and all, even the iMac, are able to connect to each other.Â
I already tried restaring the Airport Extreme, zapped the PRAM, reset the SMC, repaired permissions, disconnected the router and Airport from the power source and it still won't connect. Last time this happened, my iMac went to sleep and dropped the Internet connection after waking. I put it back to sleep and woke it using the power button as someone had suggested in another post, that helped and the connection was reestablished. This morning the iMac it was working fine, did not go to sleep at any time and suddenly dropped the connection, which I haven't been able to restore since.Â

At least 2-3 times daily my brand new Imac drops the connection to my home network- I have tried to reboot my airport extreme- my ipad and iphone and nest thermostat do not have these issues of dropped connections. As soon as I click the pale wireless signal at the top of the imac, it finds my home network and joins again, but it is a drag to have to redo this every time I want to stream music around the house or check my mail. All of my updates are current.

I upgraded to Lion after its release and ever since then my wifi has been driving me crazy. The wifi disconnects, and when I click on my network I get the error that the connection timed out. I'm always forced to turn the wifi off and then back on. It happened a ton, and consistently. It's extremely frustrating especially when I'm in the middle of a movie on my Apple TV and my iMac loses its internet and interrupts the show. Sometimes it happens three or more times during one show. So I decided to do a clean install of Lion. I made sure all my important documents were on my Hard Drive and even wrote a list out of every application that I use regularly. Then I completely reformatted my hard drive and did a clean install of Lion.

MacPro wifi connection dropping from time to time I'm having a strange issue around my MacPro 1,1 2006. When I startup the computer, the wifi runs fine, good connection (all bars), fast response, etc... But something like 20 to 30min after that, the wifi logo still with all bars but even google doesn't load. So, my network is a modem and 3 routers, the first one is a Linksys that goes through cable to a Time Capsule 1TB (were the Macpro connects) and from there to another router in the floor above, a Pacific wifi. My Macbook Pro 15" connects perfectly to my time machine, but the MacPro have this issue.Â

I have a new iMac purchased in Q1 2014 and connect my G-Grive to it via an Apple Thunderbolt to Firewire 800 adapter. My iMac runs 24x7 and this FireWire 800 hard drive connection drops out on a regular basis - I'd say maybe once every week or so leading to a dismounted drive and an unavailable iTunes library. I have a slightly newer USB3 G-Drive which is connected by the USB socket next to the TB socket on my iMac. This one doesn't drop out/dismount. I cannot tell if it is a software issue or a physical (cable movement issue), the plug has never been out and I can't deliberately disconnect it at will by wobbling the cable/plug.
So, evidence and experimentation suggests the physical connection is not the issue. This problem has only come about after switching from a physical FW800 connection (my old iMac) to working via a TB adaptor (my new iMac). I'd rather not replace with more USB3 G-Drives (lack of free ports) and I'm not sure if I want to invest in a TB drive if the connections cannot be relied upon. I've seen lots of complaints of TB-FW800 connections dropping on MacBooks but did not see a specific solution. .

Two computers in the house MacBook and iMac, running on an Airport Extreme network, which includes an Airport Express plugged into the stereo.
A brief power outage the other night (perhaps unrelated), and in the morning, the network was wonky: the iMac was only getting two or three bars, streaming radio to the Express kept flickering on and off. When that happens, rebooting the Airport base station, the router, and the Express usually takes care of it.
Since the reboot, the iMac hasn't been able to keep a connection to the network, and often can't find it. It may start off, but then loses the connection and then times out trying to reconnect. Or the network doesn't even appear in the list. Read that launching Network and running Diagnostic will fix problems and it sometimes does, but never for long.
All this time except for one brief bit where it suffered the same problem the MacBook has had no problem connecting to the network and the Internet.
Have rebooted everything multiple times in various orders, run Disk Utility, and even gone ahead and upgraded the iMac to Snow Leopard (laptop was recently upgraded).

I know there are a lot of similar threads all around different forums, but nothing really helped and I was hoping some of you smart ladies/guys can help solve this issue once and for all.
Here's the deal:
My main desktop computer (Compaq windows XP computer) is set-up upstairs where the cable router and linksys wireless router are placed (which is right next to the desktop on the desk). My Macbook (running Tiger and is 3 years old) and iMac (running Leopard and is not even 1 year old yet) are set-up downstairs in my new office. This room is in the basement, however the room is almost directly above the main office where the wired desktop computer resides.
Prior to setting up my office downstairs, my sister lived with my family in the basement and had her windows Vista laptop set-up without any internet connection issues. Her internet never dropped on her laptop, and neither did the connection on her wireless all-in-one printer/scanner/copier. Cell phone reception/internet connection in the basement is also great.
When I set up my iMac and Macbook however a few weeks ago, the internet keeps dropping connection! I do not understand this when my sister had no problems at all with her laptop getting internet connection, when she was living with us. The internet connection will stay good for either 10-30 minutes and then drop, or it could be good for up to an hour and then drop.

I was on my Mac and this happens somewhat often. I loose wifi connection and I have to go to the little wifi tab and select my network again. It doesn't ask for my password but it connects again. I am quite irritated with this, and it is embarrassing when my friends who have pcs come over "you have got a stupid Mac!" I love my Mac I don't want to ruin its great reputation.

I have a 2011 iMac 27 inch I purchased in around December. I have the most updated version of OS X Lion. My wifi connection to my router keeps dropping and losing connection. This does not happen to my other devices (MBP, iPhone, iPad). There was a fix for OSX Lion which worked for a bit but now it's happening again.

installing the 10.7.4 update on my 2011 iMac 27". The symption is that the iMac drop its Wifi connection after a period of time and when that happens the iMac cannot detect any wifi networks in my area (disabling & re-enabling Wifi on the iMac doesn't help). I have to resort to restarting the iMac to revive the wifi interface. Note that my other devices (including my iPhone and my MacBook Air)can connect to my Airport Extreme without any problems.

My imac constantly drops my wifi connection. Sometimes it'll last 5 minutes, other times less than a minute. And, yet other times, it'll go on for 30 minutes. I've tried deleting the network and the adding it again, reset router, changed channels on the router and countless other solutions with no success. Sometimes, it does not even find my wireless network! My ipad, my wife's macbook pro and my mac air all seem fine on the network and do not drop the signal. What is going on? Could it be my wireless card? Is there any easy way to check if I have a faulty wireless card?

I've iMac OS X Lion 10.7.3 latest version desktop. For couple of months, I'm dealing with dropping wifi connection during working. Every a few minutes, even during surfing though internet pages, wifi connection drops. When you look at the signal level etc.. everything is seems to be fine, but it is not possible to connect internet after close-open wifi. For a while, connection drop happens again.
