IMac constantly dropping WiFi signal

Hi,
I bought a new iMac in August and every since upgrading to Yosemite i constantly have problems with my WiFi dropping all the time.
I have been on the phone to apple who got me to do hard resets etc but nothing seems to have improved this.
Has anyone else had this problem and if so any advise!!!

And here's a new article from OS X Daily that might apply: Remove Bluetooth PAN Helps Resolve Wi-Fi Conflict in OS X Yosemite?

Dropped WiFi signal, with a twist.

So I've read some earlier posts about Macs running SL dropping Wifi signal, which is consistent with the problems I am experiencing. Ever since I upgraded to SL, wifi signal has been dropping intermittently, maybe about 5 times a day. Running 10.5, these problems never occured.
The twist is, my entire network shuts down. Even PC's connected to the network drop their signal. I have to wait maybe about 30-60 seconds for the network to come back up. I know it's a far stretch to assume an operating system is causing my router to somehow shut off its signal, but the timing of upgrading to SL and having these problems is uncanny.
I have already called Linksys tech support and they instructed me to upgrade the firmware (I have the WRT54G V2 router, which is only about 1.5 years old, so I doubt the router has gone bad). At first I thought this did the trick, but the problems came back, although with less frequency, which is good. But it's still annoying!
Any help or incite is helpful.

Hey Nvius,
I have kind of the same problem, even in other then my own, wifi environments, i cause the whole network to crash. i tested this several times at a friends house. When i start my macbook and connect to the wifirouter, all other wifi clients loose their entire bandwidth. They stay connected to the rooter, excellent signal strength but impossible to access a site or even connect to the routers setup page.
Did you find a solution for your problem?
thnx,

Dropped wifi signal

I live at an apartment complex that provides wireless internet connection. I've moved to another unit in the same complex and now, instead of having the internet antenna only 20 feet from my computer, it is now about 40 YARDS from my eMac. What is frustrating is to be browsing the 'net only to have the signal dropped all of a sudden with my eMac telling my that I am not connected to the internet. It usually doesn't reconnect after restarting the machine and it sometimes reconnects after I put my eMac to sleep for around 4 or 5 hours. Would it help to boost the wifi signal by purchasing an external antenna? If so, where on my eMac would I connect the antenna? If an external antenna is not the solution, does anyone have any other suggestions to solve my problem? I also recently had Elgato's EyeTV200 installed and I'm wondering if it is part my signal dropping problem. Comments? Suggestions? Thank you to all who respond!

Okay, I tried reinstalling OS X and it didn't solve my networking problem. However, something really weird came up. Another discussion site suggested that I try increasing the signal strength via a product from Quickertek. I contacted the company and they suggested to download iStumbler to test how much of the wifi signal my eMac is receiving. If it is 30% or less, he said, than I should consider buying their product. Well, not only did iStumbler indicate that I was receiving up to 70% of the complex's wifi signal, I was able to connect to the internet! Hallelujah!!! My computer would still drop the signal, but only after about 2 hours or so. Much, much longer than before. Not perfect, but acceptable. Everything was going okay until I followed the advice of another person on a discussion site which was to use Disk Utility and make sure everything was okay. I fired up Disk Utility and had it repair permission. Big mistake. It made many permissions corrections, but I am now unable to connect to the internet at all. It doesn't make sense to me that repairing permissions would cause this. But, all I can tell you now is that no matter what I try, I am unable to connect to the internet. My eMac is also unable to pick up ANY wifi signals from anywhere, even from my own DSL modem which is only eight feet away. I've tried Network Utility, reconfiguring the machine, and I've run out of ideas. Suggestions?

JERRY HELP laptop keeps dropping wifi signal, very slow computer

I have read some blogs here where Jerry Lippey? has helped. PLEASE HELP!! My c655d-s5200 satellite laptop constantly drops the wifi connection. just in the registration for this site alone i had to reconnect about 10 times. computer is only about 1 year old. computer has always been very slow, even from day 1. taking sometimes a full minute or two to change pages. I never complained about it when it was under warranty. I just lived with it. and now that it just out of warranty, I have changed from mediacom cable to us cellular wifi, I am finding out that I have more problems than I thought. I have a good 4G singal and I am almost 100% sure it is not a problem with the hotspot. it seems my computer takes way to long thinking. even from day 1 sometimes it will not print a letter that I know I typed. It has most of the same problems as the person on a ship overseas did in another blog. If you havnt figured out yet I am NOT familiar with the computer. or tech terms. I am one of the dumbest ones on here. I tried to search and identify my wifi information by typing (pc diag ) in the search bar and no results came up. As I was going to try and redownload the driver. I still have the windows 7 that was originally loaded. I also have NO dates set to restore to. can someone please help me out. I am very disapointed with this toshiba computer. PS it just took over 40 seconds to back space and delete a full sentence I decided not to say.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

IPad 2 keeps dropping wifi signal

Hi all, I'm hoping someone can help with a very frustrating problem.
I have an iPad 2, running iOS 6.1.2 (10B146). My home wifi network is provided by BT Infinity (I'm in the UK), via a BT Home Hub 3. Very frustratingly, my iPad is dropping my internet connection, frequently but seemingly randomly.
The wifi is stable for all other devices (iPhone and laptop), I never experience drop outs with either of those devices.
I've tried re-booting my router, but this hasn't helped. On my iPad I've tried Resetting Network Settings, but the problem persists.
When I lose my internet connection, I don't actually lose my wifi signal, the wifi icon remains in the top left corner, and the correct wifi network is still 'ticked' under my wifi settings. The only way to restore my internet connect is to turn my wifi off and on again, this solves the problem until the next disconnection.
It's driving me mad at the moment. My ipad appears to be fine when connecting to other wifi networks, which led me to think it's a problem with my router. But the fact my other devices are not dropping connection leads me to think it's a problem with the iPad.
In my wifi settings on the iPad I'm using DHCP, no HTTP proxy.
Any suggestions would be much appreciated!

Hmm, the problem continues. Switching to Sky is starting to look more appealing!
How will changing ISP fix a wireless problem? There will still be the same number of interfering channels.
If you think the problem is related to the home hub, then simply add a separate cheap wireless access point, that is what other people do.
You can also use a different router if you wish.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

IPad 3 keeps dropping wifi signal

Despite having a very strong wifi signal around the house, which my iPad 2 has a strong connection to, my new iPad keeps dropping the wifi signal every minute or two, making using the Internet nearly impossible. To regain connection I just have to go on the wifi settings page (not even turning the wifi on and off) which then gives me the signal again. Ive tried resetting network settings, but nothing works. Please help; this is a real problem and means I can't use my iPad properly.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

My new iMac continually drops wireless signal

Anyone having issues with their imac continually dropping the wireless connection?

Well the solution was short lived and after leaving the laptop in sleep mode for a couple of hours the problem was back. Originally I was told to copy my system configuration folder ontop the desktop and restart my computer. With this only being a short term fix I called back again this afternoon and I was walked through setting up a new location which included adding 2 dns server addresses (208.67.220.220 & 298.67.222.222). Once again this was a short term fix. The next step I was advised was to change the channel of my rotuer. According to the apple advisor they have some reported sucess with users changing the router channel from automatic or 1 to either 6, 9 or 11. I've just changed mine to 9 and after resetting the router and laptop it seems to be working again (longer than it normally lasts). If this fails I guess I will try changing the router to the other channels suggested and if that doesnt work the next piece of advice was to re-install the OS. Interestingly a friend bought the same mac book pro as me and his is working perfectly fine even when sharing the same connection. Very fustrating! Good Luck.

2011 17" Macbook Pro constantly drops Wifi connection on Windows 7 but not OSX. What's going on???

On OSX, the Wifi works perfectly. I rarely if ever get disconnected from the internet. However, when I switch over to Windows 7, the internet drops constantly (every 30 seconds or so).
I recently updated my OSX to the newest one (I think Yosemite) that released in December, which wiped out my Windows 7 operating system. Thus, I reinstalled windows 7 on my computer and everything works just like it used to except for the internet dropping 24/7. The weird thing about it is that whenever I "diagnose" the internet connection when it drops, the internet seems to come back to life again (for the short 30 seconds that it's up). I'm not sure why it's doing this. The internet didn't drop constantly on my previous Windows 7 until I reinstalled it.
The internet works fine with a different internet connection on Windows 7, which makes me think that the problem has to do with my internet or router... Has anyone had this problem? Restarting the router didn't do anything.

Do yu have any other Macs running Yosemite on your WiFi Network?

My brand new iMac keeps dropping wifi connections

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. Any Ideas? All of my updates are current. Thanks

This has helped some although, unfortunately, not everybody:

IPad 2 constantly drops WiFi connection when tethered to iPhone via Hotspot

I have a wifi only iPad 2 that I tether to my iPhone 4 via the personal hotspot. The iPhone and the iPad are constantly being separated throughout the day and my problem is that when the iPad gets back in range of the iPhone hotspot it won't reconnect at all! In fact the iPad no longer sees the iPhone as a wifi option in the network list even though the iPhone hotspot is running just fine (other devices cam still see and connect to the iPhone hotspot)
I have to turn off the iPhone hotspot, wait 2 seconds and then turn it back on. Then the iPad sees the hotspot again and connects.
Also if I turn the auto lock off on the iPad so that it never locks, then it will reconnect to the iPhone hotspot just fine. But the problem with turning auto lock off is that the screen has to stay on all day!
There is obviously something wrong that is happening when the iPad locks. It drops the wifi connection and then does not reconnect when I turn the screen back on.
Is there anything I can do to make sure the iPad reconnects to the hotspot whenever I get back in range without having to keep it on all the time?

Re: iphone 4s - HOTSPOT - WILL NOT STAY CONNECTED
Mar 13, 2012 1:20 PM (in response to coalxman)
I have been having that problem for 6 months and my IT guy finally found a solution by mining the web. I don't know the source of the answer to give credit but it works !
Text of blog posting below:
t does, thanks! I was getting really frustrated with connecting my iPad to my 4S via Personal Hotspot. After a fresh boot of the phone it would work as expected but if the connection was terminated (say by switching hotspot off and on) or after the two hadn't been connected for a while it got into this state where I could see and connect to the hotspot but it would drop a few seconds later then try again over and over.
After a lot of experimenting I finally figured out that there seems to be a pretty serious bug in the hotspot's DHCP server. AP discovery and WPA authentication work great but in this weird state the iPhone will not give the connecting device an IP. The only solution to fix the DHCP server is to reboot the phone.
That being the case, grasshoppertrekker's advice is bang on - you need to give the connecting device a static IP address. This gets around the DHCP issue.
For the less technically inclined, here's how to do that with an iPad:
- Reboot your phone and connect to the hotspot as usual and ensure the connection works
- On the iPad go to Settings - WiFi and tap the arrow to the right of your iPhone's name
- Write down all the values you see under the DHCP tab
- Tap the Static tab (or Manual)
- Enter in the same values you just write down
- Hit "WiFi Networks" at the top to go back
The iPad will now reconnect using the same settings as DHCP would have given it, but without relying on the broken DHCP server.
Optional extra: Instead of using whatever DNS values the DHCP server (and by extension your mobile data ISP) gives you, use OpenDNS IP's instead. This will speed up YouTube due to their partnership with Google and prevent your ISP from traking your web usage via DNS interception. To do this enter the following into the DNS field under the Static tab: 208.67.222.222,208.67.220.220 (note the comma)

Imac suddenly dropping wifi connection

Hi, my imac is connected to the wifi network and has worked fine for months. Now when I'm surfing the web it will be working and then hangs and won't load new pages till it times out.
But it's connected to the wifi network as I can see the wifi icon showing this. Also, I'm using my laptop (windows) next to it and it's connected and working fine (writing this email on it).
OS: 10.8.3 Not updated recently, and it was working fine
Imac: 3.1 ghz with 12 gig ram
Turning the wifi off and back on fixes it for a few minutes or hours. Any ideas?

Gary,
I have been having this problem with just one of our iMacs in our house. I went through Apple support and navigated through all the twists and turns they suggested to try to get the problem solved. NOTHING WORKED. THEY DON"T KNOW HOW TO FIX THIS PROBLEM. BUT I DO! Unfortunately it involves buying a $30 wireless ethernet adapter (I got an IOGEAR, and I have no connection to their company. Probably any wireless ethernet adapter will work). I turned off the internal airport wireless device and through the network settings in the system preferences connected to my CISCO LYNKSYS ROUTER (which has been bashed left and right in the forums here). THE PROBLEM IS SOLVED!!!!! NO RESTARTING!!! NO DROPPED CONNECTIONS!!!!
So the problem isn't with the router, its with the airport wireless adapter in the iMac. It stinks
to have to spend more money after you lay out so much for an apple product, but it sure beats restarting the computer over and over every day.
Hope this helps my friends out there. I can now allow my hair to repopulate my head since I've been pulling it out over this issue for months.

IMac Continually Dropping WiFi Connectivity

Due to appalling wired "broadband" where I am, I have to connect by tethering an iPhone 5 over an HSDPA cellular connection. That's all fine.
The trouble is that my late 2012 27" i7 iMac keeps losing connectivity although it continues to be - apparently - connected to the iPhone. Symptoms include no Internet connectivity, dropped connections to the Apple TV, etc.
None of my other equipment is affected, so it's not an overall connectivity issue, just with the iMac.
Is this a widely known problem?

Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article. If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Run Software Update and install all available updates for OS X or your computer's firmware.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it. Note: this is not applicable to OS X 10.9 or later.
Step 4
This step will erase some of your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with "com.apple.airport.preferences.plist" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Recreate your settings for Wi-Fi in the Network preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
