Losing network or internet connection after sleep/wake

Between your response and poppincurbs, I think I will invest in a different router and give that a try. It's just that every "fix" posted seems to work (some worked for weeks!), and then the problem mysteriously reappears. I would hate to purchase another router only to find out in a few weeks that I'm back to square one (and I have been working on this problem for over a year). I hope a new, non-Apple router is the answer.

For what is worth, my router is a TP Link and this was driving me crazy until I used the solution outlined in the first post. (MBP mid 2012 running 10.9.5).

I still get some disconnects from time to time, but the missing wifi after waking up is gone.

I have followed Reforger's suggestion, but it was certainly temporary. We had maybe two good weeks, then the drop-outs started again. Thank you for posting--you may have saved me from purchasing another router. I also had high hopes when Yosemite came out, but apparently that OS has wifi drop-outs as well. Wish I could go back to Mountain Lion.

Evening!

I thought i had posted an update, but i don't see it...anyway, operating off my service provider modem was not consistent (while still operating my Airport Express modems - for the iOS gear in the house...). However, it was an easy fix to use my phone or pad to reset the AE (Airport Express) modems using airport utility. Took 3 minutes i suppose.

As you may be aware, Apple provided an update a couple days ago for Yosemite. This update, so the info indicated, was to specifically address the wifi faults. I updated and have been using the AE modems since with about half a dozen "sleeps" and "wakes". No problems so far.

I doubt Apple will be updating old OS versions - so you may not see improvement - ever, until you update to Yosemite...

What you posted made sense--why am I still fussing with Mavericks, when there is a new operating system to try? So I upgraded to Yosemite, and there have been no drop-outs since the upgrade last night (and I had to click on and off my wifi icon repeatedly towards the end of my time with Mavericks). So that's a good thing.

We are getting a lot of spinning beachballs, however, with a lot of things we click on, and I've had to force quit Safari, Pages, Adobe Reader many times in the short time I've had Yosemite. Sheesh, I hope they work these bugs out! At least I'm not having wifi dropouts, but so far with all the spinning beachballs we are not impressed with this upgrade.

In my experience, the only way to make the spinning beach ball of dead go away in those cases is erasing the hard drive and doing a clean install of the new OS.

You can also try repairing permissions and verifying the disk, but if there is some incompatible items left behind by software you installed at some point, a clean install is the safest solution.

Thank you! After weeks of frustration you've saved me a call to the Mac specialist and probably hundreds of $. I thought I was going crazy when my Mac was the only thing in the house not connecting to the internet.

The only software I have downloaded that did not come with the computer is Adobe Reader. I have reset PRAM and so far, so good, (I don't even know what resetting PRAM means! I just followed the directions I found online.) If the symptom recurs, I will follow your suggestions. Thanks.

Well, Yosemite disconnects wifi, too! Just not as much as Mavericks, thankfully. So now I will move on to the Yosemite wifi disconnect discussion, knowing full well that NOTHING I do is going to make a lasting difference until APPLE figures out what it is doing wrong.

Reforger,

Thanks. What a relief! All I did was disconnect my AC chords to my modem router and Mac in anticipation of a flood where I live. Thank God for no flood. However, for some reason the symptoms you described happened after I reconnected everything.. I would renew the DHCP. I would manually change the address. It became a huge pain everytime I booted up. I tried your solution and then booted up. Everything works GREAT! No need to be put on hold with my service provider. LOL. Thanks again!

Thank you very much for this response, worked first time.

F my life. I've got this problem, too, with my Mac Mini and Yosemite. Trying various remedies, I tried turning off Bluetooth.

"Hey, why do I have Bluetooth turned on, anyway?"

"Oh yeah, I have a new wireless mouse and keyboard. I guess I should turn Bluetooth back on. I just click right here."

"Hey, why is my mouse unresponsive? Oh...."

Of course, there is no corded mouse in the office, and it's the middle of a business day.

I realize it may be too late now but it could be useful next time.

You can force a shutdown with the power button, turn on the machine again and if not mouse is connected, the Blue-tooth assistant will come up asking you to turn your mouse on/make it discoverable.

Worked for me too. However, I wonder if it would not be adequate to simply change the service order int he Automatic location and accomplish the same thing.

Thanks a lot Reforger, it worked great!

I was really getting tired of switching WiFi on/off every time my MacBook woke up.
