OS X Yosemite :: WiFi Will Drop At Random On IMac
Dec 1, 2014
I have an iMac late 2012. Since upgrading the OS to Yosemite, I have had random drops in my wifi. I have already tried 'forgetting the network' and Deleting the system config stuff. I still get this random drop. My computer is unreliable. Dropping during an online exam is bs because it screws everything up.Â
I have never experienced Wifi drops in my life and I am starting to get annoyed with this.Â
My keyboard and mouse is using bluetooth... Does that have something to do with it? Should I just install and use Windows instead?

Recently searched the history of my iMac to see just what was loaded into the system. What I found was that there were 3 different WI-FI networks on my iMac and I would like to know just what they belong to? One is called "Orangecat", another is "wildchild" and the last one is also "wildchild-guest". What these accounts are associated with and if they are part of the internal configuration of my iMac?

So i wanted to send a 600MB file via mail drop, but when I dragged the file onto the mail window and hit send, instead of the window asking me if I wanted to send it via mail drop, it just started sending it. Now I have a slow connection and don't want to spend the next 90 minutes uploading something that cannot be downloaded, never mind clogging up my internet connection.Â
Incidentally, in trashing the uploading file in Mail's Outbox to stop it, I can see the upload still continues as my network stats show full upload speed. Had to restart.

My one month old iMac does not maintain an interent connection for very long. Sometimes it stays connected for <maybe> an hour, but MORE often it drops either the wifi signal all together or just stops connecting to the internet... when it does seem to have a connection it is VERY slow. Â
My solution: turn off Wifi wait a few seconds and turn it back on... which is very annoying, but that fixes it. Â
I have the latest software across the board. I'm running wifi on Time machine. My signal is strong. I have a Powerbook and iPad that connects to it without issues (for a couple of years its been fine until this iMac problem).Â

There is a problem of a periodic signal loss. The reason for this is the password reset network settings in the airport. It happens randomly during sleep. The system log says only connect and disconnect from the network. What may be the reason?

My 4 year old macbook air has become nearly unmanageable when playing on-line bridge. The cursor flits all over the cinema screen tho is stable on the laptop lcd. Also, the wifi drops off intermittantly, and takes upto 2 minutes to refind. The software is original, but up-to-date.Â

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.

Why does my iMac continue to loose wifi connection? My PC setting right next to it does not have the problem. I'm trying to do the switch to iMac but having a tough time. My 1986 DOS PC with 20 Meg hard drive sure was simpler.

I recently around 3-4 weeks ago update my Mac Book Pro to the new Yosemite software and everything was going fine until I got onto my internet! i was connected to my home wifi and everything was fine! Click into something and said I wasn't connected..! I looked up to see the wifi had disconnected! So i thought it was just a fault in my wifi modem, i manually clicked my wifi again it connected. It wasn't until after the 6th time it happened that i realised it wasn't my network and that it was my laptop! now everytime im watching a movie online or youtube its get disconnected and I have to continuously manually connect to my network! This happens every 2-3 minutes and had been frequent since I have updated! It's super annoying as it interfers with my regular web surfing and have looked for and tried so many things to fix it and nothing seems to work!

I've been dropping my wifi since the update. It drops all the time regardless of what I am doing. I have to shut off and then turn on wifi again to show listed. The router works fine with other devices (iPad, iPhone etc) plus my PC.

New-out-of-the-box computer. I've tried creating new network connections -- and other configuration - but no internet pages open. The screen message says "You are not connected to the Internet."Â

Macbook Pro (Mid-2012) Which I purchased 4 months ago.Â
It keeps dropping the signal about every 5 minutes, only on my home network. It's only this device too, since my phone and all of my roomates' devices are unphased. (streaming videos like it's no big deal)Â
This started happening after we lost connectivity with the snow a few days ago here in Seattle. I have tried all sort of troubleshooting, including the DNS thingy and restarting the router.Â

After upgrading to Yosemite 10.10.1, my MacBook Pro has been randomly disconnecting from the WiFi access point. Nothing has changed settings-wise, and none of the other devices have the same issue. Here's my log when it disconnects:Â

My problem is at home the wifi works great but at work or on a public network it disconnects every minute. Only happened since upgrade to Yosemite. I'm aware lots of people are having issues with WIFI since upgrading to Yosemite.Â

I've been having Wi-Fi issues with Yosemite (both 10.10 and 10.10.1), but only on my home network. All other wi-fi connections have been strong/reliable. I also ran the Yosemite beta from July (I think) until the full release, but did not have any similar issues with wi-fi. Â
Here are my hardware specs:
Plus a 500gb hard drive.Â
Here's the info on my computer's wi-fi card, and my wi-fi network itself. Router is a Linksys E1000 (which is ancient, I know, but I can't afford a 5.0GHz router right now and that seems like the only worthwhile upgrade).

I'm on Yosemite; on both my iMac and MB Pro, I can't put the computers to sleep when it's connected to the wi-fi; I have to turn the wi-fi off, and then it'll go to sleep. I'd like to be able to keep the internet connected when want to do this.

Since upgrading to Yosemite my Wi-Fi connection is awful! It connects and disconnects every 10 seconds, this has only happened very recently so I think its linked to the upgrade to Yosemite...Â

this evening, a neighbor's xfinity wireless network kept flashing what appeared to be web pages on my MBPro screen. They weren't attached to any browser I was running.Â
I'd close these pages (ads to join xfinity) but they'd keep coming back. Then I noticed that I'd been booted from my own wireless network, and xfinity was the active network!Â
It feels predatory, this behavior. How can I set up our Macs to prevent this ever happening again? When I join our wifi in our home, I don't want any other signal to elbow in, so to speak.Â
Or, if there's some kind of interruption in our wifi signal, I don't want some other network elbowing in.Â
However it happened, how can I set it up such that, if I didn't authorize a wifi network, it will be prevented from joining me to it?

I think there is an icon error in OS X Yosemite. The third icon above is slightly larger than all the other icons, distorting the WiFi signal when searching for a WiFi network.

The bluetooth badly interferes with the wifi - with bluetooth on, wifi download is around 1mbps; without bluetooth it instantly jumps to 10+mbps. Problem is - I need to work on an external monitor with the bluetooth keyboard and trackpad.Â
Have tried altering wifi channels etc.
