wifi keeps dropping since Yosemite upgrade

Since upgrading to 10.10.1 my Wi-Fi/Bluetooth problem was working fine for well over a week then suddenly for no reason it started yesterday, magic mouse started jumping and stopping then the Wi-Fi looses signal until I connect it again, this is happening every 2/3 minutes, checked my tx rate and it was 245 and phy is n so no reason at all to happen. This is effecting my business and I'm not happy, thinking of going in to see my business manager in Apple store to see what he says. Really not happy at the mo.

I have tried - and succeeded for about a day each time - with most suggestions (sleep,restart,switch off; SMC reset; new network name etc) but this morning I found this on BT's Home hub:

"The BT Home Hub 4 and Hub 5 are dual band with two wireless frequencies for devices to connect to: 2.4GHz and 5GHz. On both Hubs, the default setting has the same network name (or SSID) for both the 2.4GHz and 5GHz bands. Connecting a typical 5GHz-capable device to this single SSID will automatically connect the device to both the 2.4 and 5Ghz frequency at the same time.

However, not all dual band devices behave the same way and some device software does not cope well with a single SSID for both frequencies.

As a result:

• the device may not connect wirelessly to the Hub
• it may not connect to 5GHz frequency even in the same room
• the wireless connection might be intermittent
• the wireless connection might be very slow

Devices where there are known to be problems include:

• Some Apple devices including iPhone 5 and Apple TV
• some Android smartphones
• Xbox

For some devices you can solve this problem by having different network names (SSIDs) for the 2.4GHz and the 5GHz bands. To set this up, follow these steps:

1. Open your web browser on a device connected to the Hub and go to bthomehub.home. This will open the Hub Manager
2. Click on Advanced Settings and enter your Hub admin password when prompted. Unless you've changed it, you'll find the default Hub password on the Hub settings card
3. Click on Continue to Advanced Settings
4. Click on Wireless
5. Click on 5GHz
6. Change 'Sync with 2.4 Ghz' to No
7. Change the 'Wireless SSID' to a new name (we recommend just adding '5GHz' to the end of the existing SSID name so you'll know which one is which)
8. Click Apply to save the changes

After a few minutes you should see two BT Home Hub SSIDs in the list of networks on your device. All of your devices will still automatically connect to the original SSID name, which will be the 2.4GHz.

If you have existing dual band devices you want to connect to 5GHz only, you'll need to connect them to the 5GHz SSID that you've renamed. BUT RESTART HUB first - PJ

Note- Even though wireless speeds at 5GHz can be significantly faster than 2.4GHz, the range of a 5GHz connection is not as good. As a result, you may need your device closer to your Hub (than you'd need to when using the 2.4GHz SSID) to get the best performance possible."

This fixed my problem, thanks.🙂

Hi Thankyou PFJ30 i have tried this and keeping my fingers crossed it works we have a bt home hub 4 so it quite promising, will let you know later after i been on for a while. Thanks again for going to the trouble of posting this.

I've had this issue forever, and it seems to get worse right after I upgrade. I realized today if I stop dropox sync, the problem goes away.

If you take some time to read the other forums, this is an issue thats been going on since apple launched Yosemite. There is not a permanent solution to this problem. What i did after trying EVERYTHING that people suggested in the support communities, was that i reinstalled a clean version of Mavericks and BAM!, my wifi is working perfectly now. Don't bend over backwards to get your wifi to work, this issue could take months to resolve, and apple is not being helpful at all, downgrade and wait! GOOD LUCK!!

Hi I had the same problem which interrupted my time machine backups. my yousemitemachine lost the connection with internet which interrupted my time machien backups. I tried as one of many tests to lett the airport utility remain open all the time while backingup and it seems that it still drops from time to time and a yellow triangel lights up briefly out but immediately airport utility find the network aggain and continue the Time Machine backup

I have the same problem as everyone else here. The only thing is I updated just before going to Thailand to start an online magazine and Apple again has put me in a terrible spot. Are they turning me into the old Microsoft. I am very mad!!!

I have to keep closing my programs and restarting. I am getting nothing done thanks to this upgrade I will never upgrade again without waiting 6 months.

How disappointed I am again with Apple. The last time recently was upgrading my iPhone only to find myself on the road and without any signal!

Just to add my four pennorth to the weight of this ....

Using my Apple Mac Pro for working from home, and experiencing the same WiFi dropouts as everybody else!

Strangely, I think mine only really started since the Yosemite 10.10.1 update, certainly never noticed it before?

WiFi seems fine when down in the office on their WiFi, but drops out every few seconds or at most minutes on my home network with VirginMedia hub.

Also connecting via WiFi extender downstairs, bit tried without and same problem.

So, I have tried all possible fixes as detailed here, but don't currently have Timeline backups setup until I buy a new hard-drive (old one given up the ghost).

Therefore can't backtrack to previous O/S, unfortunately, and the other methods look dangerous and cumbersome with lots of opportunity to make it worse! Anyway, would never attempt these levels of things without ensuring I have backups in place first!

So I agree! Pull your finger out, Apple, and get a further Yosemite update as a matter of priority - but please, only when you've tested it first, and we can be reasonably confident it won't make things worse!

I had the same problem. After updating to Yosemite, my wifi continued to drop and I had to repeatedly click it back on with the wifi icon.

I tried every solution in this website.

I then moved the computer to another home and wifi and it worked perfectly for 2 weeks. No drops at all.

Then I returned to the home with the dropping program and once again, I was continually dropped off the system.

Thanks to my son who is a expert in technology (Rex Electric in Chicago) he changed a few things on my router including the channel that was dominant.

After a few minutes, the system came on and has been perfect for 3 days now.

My conclusion is that there may be some router issues with Yosemite. I am now a happy camper.

Get someone to change the channel on your router....

A possible fix for constantly dropping Wi-Fi.

I recently upgraded to Yosemite and like many others lost my Wi-Fi internet connection.

I live on a boat and depend on my Wi-Fi connection to tether two laptops to my smart phone.

I have two MacBook Pro’s, both were on Lion and I upgraded one straight to Yosemite (in case it is relevant, I have pasted below, the hardware/software spec).

I changed nothing except the Yosemite OS upgrade and the second Laptop, running Lion, continued to hold its Wi-Fi connection as normal, so I knew the problem was Yosemite.

The newly Yosemited laptop would hold Wi-Fi for only 40 seconds.

I tried all the usual ‘tricks’ suggested on various web sites and forums and none of them worked.

I upgraded the smartphone OS from windows 8 to 8.1 but this made no difference.

I have, however, now found a fix.

Fed up with the constantly dropping Wi-Fi connection, I got a bit OCD with the reconnect button.

To reconnect, I normally click the Wi-Fi icon in the command bar at the top of the screen then from the dropdown box, select my network.

As I say, this time I got a bit OCD and repeated this reconnect routine 30 times in quick succession ( long enough to cover the 40 second period it would normally drop out in, it may well work with less) and BINGO! my Wi-Fi stopped dropping out.

I discovered this yesterday and it has held ever since, including a period of about 6 hours web surfing while I did some research. I have disconnected and reconnected several times and this routine, whilst not high tech, does work every time. I do have to do this every time I connect otherwise it reverts to constantly dropping out.

Hope this helps someone else because I know how frustrating these problems can be, especially if, like me, you have no alternatives.

By the way, I have used all sorts of OS over the last 30 years (starting with Dos) and know that it is not unusual to feel a bit disappointed when changing the interface, probably a lot of the time, simply because familiarity is comfortable. This is the first time that I actually really liked the new interface from day one.

Cheers.

Hardware Spec -15” Late 2011 / 2.4 GHz intel Core i7/ 8GB 1333 MHz DDR3/AMD Radeon HD 6770M 1024MB. Tethered to a Nokia Lumia 625 using Windows 8.1 and a 3mobile network.

For me everything worked nice until today I switched the WiFi settings to 5GHz (802.11n dual), in my TimeCapsule. Now it keeps dropping all the time 😟 I had the same settings before in the same TimeCapsule, the same MacBook pro, in Mac OS X 10.9 and I never had a problem... I don't want to switch back to 2.4Ghz because there is a lot of interference in all the channels... :/

I can verify that allen1911 is onto something with the Router Channel Switch. My Wifi was dropping continuously just today. I logged into my D-Link router and manually switched to Channel 11 after disabling the channel auto-scan. i've now been connected to my same Wifi at home for over 4 hours without interruption. The Channel Change Definitely made a difference. Just not sure if it will be permanent or not.

It looks like running Wireless Diagnotics (hold option key -> right mouse on the wifi icon on the menu bar ) fixed the frequent wifi connection drop problem on my IMac. Now the name of my home network appears at the top of wifi network name list and the connection is solid.

I have also had internet connectivity problems since upgrading. Wifi would not stay connected longer than 1-3 minutes. I called AppleCare twice, nothing was fixed. Went to the Genius Bar, waste of time. Then I found this thread. Some of the fixes (like removing the wifi capability altogether and re-adding it) helped keep the connection for up to an hour, but still persisted. I have tried several of the other suggestions here. Some have helped ease the problem, but none so far fixed the problem permanently, until…

I tried resetting the SMC as described. That seemed to fix the problem, but after trying so many things over the course of a few weeks I wasn't convinced.

So after resetting SMC, I also was inspecting our router settings and found "configure number of concurrent users that can be logged into the router" which was set to 5. I changed this to the max for our router: 10. So far my wifi has been steady and my MacBook Pro has been connecting on it's own (rather than me selecting our network) when I open the computer.

My connection seems more stable now, but not 100%. I hope this helps someone else. Apple, we need a patch release STAT!
