Still no fix for dropped Wi-Fi after waking up from sleep... I spent 15 minutes (really, I timed it) this evening closing and opening my MBP's lid until I could finally connect to my wireless router (which is literally 7 inches to the right of my MBP). If you don't know what I'm talking about, read this: http://osxdaily.com/2011/11/06/lion-wi-fi-problems-solution-mac/ http://osxdaily.com/2011/11/06/lion-wi-fi-problems-solution-... - About 300 people have posted on that topic, it's really widespread yet it hasn't been fixed after 15 months. You can also google "lion wireless problems" to see literally thousands of post on online forums about this problem. And a good news to all fellow iOS users: This "feature" (read "cancer") has spread to iOS 6 betas as well.

Is there a reason that you have to open/ close instead of just giving airport a kick in the pants?
- pooriaazimi 14y ago
  Turning Airport off and on doesn't seem to fix the problem for me, so I have to close the lid. My father's MacBook on the other hand only gets fixed when you turn off/on the Airport from the menu bar.

There was a similar issue with Snow Leopard and I would not doubt others had it with Lion. What irked me in my case was my first year i5 iMac (the i5 in twenty seven inch form) was perfectly fine until I upgraded. Then suddenly wireless may or may not work upon waking from sleep. The odd part was, it might work for a few seconds after waking before I would have to manually end it and connect again. It was talking to the Airport Extreme just fine, it could not get beyond it. The kicker, the copy of windows which I ran through Parallels could connect. I could surf sites and VPN through Windows in a VM while OS X applications could not, until I bounced the wireless connection.

Try turning off your bluetooth. I had the same issues with wifi reconnect after sleep and they went away after turning off bluetooth on the laptop.

  I have bluetooth off on my Air and it still has this wifi issue. Its some race condition because it doesn't happen all the time and for it only happens when waking up from a deep sleep(ram persisted to disk).

Have you tried: "To fix this, I removed all the remembered locations and then in Configure Network Prefrences -> TCP/IP changed Configure IPV6 to Link-local only." EDIT: It did seem to make things better for me, where after waking up from sleep it at least automatically reconnects, but it is still not same as Lion I think.d
- pooriaazimi 14y ago
  Yes, but no luck...

I have found ever since upgrading to Mountain Lion that waking up is iffy in general. The login screen displays, but it can take anywhere from 10 seconds to several minutes before I can type in my password. Sometimes it takes so long I just force the machine down and reboot instead.
- nodata 14y ago
  Same here: with Lion - open lid, type in password. Mountain Lion - open lid, push first character of password, no response? keep trying again until asterisk appears, then type rest of password.

    Another vote on this. Annoying "issue".
  - Reebz 14y ago
    I close my lid and my MBP (last of the 17" line) never sleeps. Really frustrating.
  - sourc3 14y ago
    I had the same issue on my iMac and it was really annoying. I found that un-checking the box that reads "automatically connect to networks" (or something to that order) helped fix my issue. It may work for you too!
    - MattRogish 14y ago
      I have this problem as well; it's my most frustrating experience with Mt. Lion so far. Where is that? I tried Spotlight searching for "automatically" and "networks" and couldn't find it.
      - sourc3 14y ago
        If you just go to Network Preferences you should see it.
marquis 14y ago
I 'fixed' this: create a shell script that pings your router every 30 seconds and add it to your launchagents. It forces the wifi to stay alive. Let me know if you'd like me to post more on how to do this. I've had this problem since Lion and my wifi hasn't dropped for months now.
maayank 14y ago
There was definitely some wifi drivers problem in the original Lion. I wrote a fairly popular blog post summarizing reported solutions to the wifi problem in Lion and what solved it for me: http://thoughts.maayank.com/2011/08/wireless-problems-with-macbook-air-and.html http://thoughts.maayank.com/2011/08/wireless-problems-with-m... I wrote it a long time ago, but maybe it will still give you (or others) leads to a solution. FWIW I haven't had any major wifi problems since the first or second Lion update.
- MattRogish 14y ago
  That matches my experience, too. I had dropping problems when I got my MBA (mid-2011) and it magically fixed itself sometime after Lion shipped. I have no problems now.
  - maayank 14y ago
    It was a major disappointment for me at the time as after years with Linux I bought a Mac exactly because I wanted to focus on my work and not on solving fringe kernel issues. Luckily, no major problems since then.
peapicker 14y ago
I had no issues in Snow Leopard, but had the dropped Wi-Fi after wake up from sleep on all Lion with my iMac/Atheros chipset and Cisco wireless n router. Had tried downgrading to 10.6.4 Atheros driver, etc, etc, etc, from the apple forums, and nothing worked. I decided to try something I shouldn't have had to and bought an Airport Extreme. No more issues. I've since sold the Cisco N router -- that had worked perfectly with every other wifi device in the house, including this same computer before Lion.

  "Fix permissions using the Disk Utility" I bet people will continue to give this suggestion as an attempted fix to random problems long after all memory of what it was actually for will be lost (i.e. classic environment screwing with HFS+ extensions introduced by OS X).
  - DHowett 14y ago
    To be fair, munged permissions are a real problem; Just the other day, Parallels released an advisory document[1] about an issue their users had been seeing related directly to filesystem permissions. I believe that "fix permissions" scans the installed package receipts and corrects the file permissions where necessary. In a world where any errant package install can mangle modes and ownership, fix permissions will not go derelict. What it's actually for is the fixing of mangled permissions.

    I still hear "did you reset your PRAM?" from people occasionally. Good times.

I thought I was alone with this. But connection drops intermittently with me, not when waking from sleep. And now I have this weird flickering cursor while typing in Mail.app God I miss Snow Leopard.
- pooriaazimi 14y ago
  Are you on Mountain Lion? I couldn't use Mail.app on Lion as it was incredibly slow. The I realized it wasn't Mail.app's fault, but GPGMail's, and now that GPGMail has stopped working in ML my Mail.app feels as snappy as ever.

What version of the MBP is this? I have a 2009 MacBook Pro 13", and two 2007 MacBook Pro 15" and I haven't had any issues at all with Wifi.
- pooriaazimi 14y ago
  2009 15" MBP and 2010 13" MacBook (white).
hnriot 14y ago
no issues here with 13" 2009 MBP. 7" - maybe you should invest in an ethernet cable...

Resetting the SMC [1] on my Macbook Air (late 2010) seems to have fixed the wifi issue. Obviously, no guarantee that'll fix it on yours... Unfortunately, I've had all sorts of other, less intermittent issues with Mountain Lion. Finder is extremely sluggish (beachballing a LOT), sleep can be iffy, and will cut in while a Time Machine volume on network share is mounted, leaving it in an unclean state and wanting to delete all my backups (!!!) and start over. (I've thus far worked around it with a full fsck and deleting only the most recent snapshot and updating the plist file to reflect this, but that's not really a solution as it takes a few hours at a time to do the fsck over the network) I'm also getting far worse battery life than before, as the system has 5-10% CPU utilisation when idle for no apparent reason. I'm hoping these have improved with 10.8.1, otherwise I'll revert to Lion and think about switching back to Linux in the medium term...
