Troubleshooting Wi-Fi issues in OS X

Network options - is the preference unlocked?

Maybe, this solution will help you.

1. Remove your preferred Wi-Fi network in System Preferences > Network > Wi-Fi > Advanced > Preferred Networks (a Wi-Fi you usually connected). Note: Don't forget to unluck your prefences if need.

2. Just join your Wi-Fi again (type password if need)

That's it!

In OSX Mavericks there is an option under Energy Saver >> Enable Power Nap that will require your network connection to remain open. it worked for me.

I'm using Mavericks and I had the same problem. I opened system preferences-network-wifi-advanced-and unchecked "turn on or turn off wi.fi". That worked for me. Jens Jefsen

Words cannot describe how angry this problem makes me. How can world's largest tech company not been able to fix their biggest bug for this many months now?!?!

All these forums are overflowing with the same **** problem: WIFI DOESN'T CONNECT AFTER COMING BACK FROM SLEEP ON MAVERICKS.

How many thousands of people have to post the same godddamn problem for how long?

And no, disconnecting Bluetooth doesn't help (even if it did, its not an acceptable solution). I took my MacBook Air to Apple store twice already and they cannot help either.

aaaAAAAaAaaAAaaarrrrghhh, I'm going to go insane from this problem.

I miss Steve.. he wouldn't let something like this go on for this long. Can a half a trillion dollar company pay attention to its own support forums or at least google "wifi-not-connecting-after-sleep-mavericks" and realize what incompetent company you have become?!

Apple doesn’t routinely monitor the discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Here was my solution to the problem. Hope this works for you and others with this problem. I was banging my head like everyone, trying different suggestions around the web none seem to work. But I stumbled across my own solution to the problem.

I opened system preferences-network-wifi-advanced - on the right hand side check ask to join new networks. Click apply. That's it problem solved

For some reason this keeps the settings when the laptop goes to sleep and when it shuts off. Hope this helps 🙂

Your solution also worked for me. Thanks!

it worked for me!!! thai Madpotato a lot (but you should do that: system reference -> Network -> uncheck "Ask to joint new networks" (Known networks will be joint automatically. if no known networks are available, you will have to manually select a network.)

I just spent like an hour trying to fix this very same problem. turns out for me it was a USB drive that (I assume) was blocking my internet connection. I disconnected it and voila! For some of you it might be that simple...give it a try...

Here is the solution that worked for me.

1. I had many Wi-Fi connections and passwords saved in my history.

2. I had two connections in my history that were accessible at the same time. The system did not "know" which one to connect to so after sleep, it connected to neither.

So, this worked:

1. Click the Apple logo in the upper left corner of your screen.

2. Settings

3. Network

4. Advanced - and select the "Wi-Fi" tab.

5. Now click the "wifi rainbow" toward the upper right corner of your screen and see which connections are accessible to you now.

6. With those names in mind, go back to the Network settings and under "Network Name," click the network name(s) you want your computer to "forget"

7. With the names you want to "forget" selected, click the minus sign below the list of network names. This will take the network and password out of your system history.

8. Click "OK"

On MacOS Sierra (i don't know if it's anywhere earlier) you go into

Energy Saver

> Power Adapter

> Now, Disable "Wake for Network Access"
