WiFi doesn't restore like it used to after sleep

Ok, spoke with Apple Support. They are aware of the problema and are pushing out a fix. The remedy that I found for my MacBook Pro, circa 2010, was to eject the disc from the optical drive. Then my computer connects to wifi without problem after waking up from sleep. Sounds stupid, but it works. Learned it from another user in this forum. Spread the word.

I am having the same problem and trying any of the fixes mentioned here haven't worked for me.

I have tried every trick but wifi on my macbook pro is still very slow. I really hope they are producing solution very quickly! I´m kinda very near of buying PC for god sake! Next time dont publish betaversion OS X to public.

I called Apple and in less than 5 minutes, they had it working just like it did in Snow Leopard. Just give them a call and I'm sure they'll be able to work something out like they did for me.

I also spoke with apple yesterday and they are aware of the problem. Said it should be fixed with upgrade to 10.7.1 I downloaded the update today as it's available - guess what, the problem is still there.

YEP...I agree and see the same thing.

No better...no worse however.

Has anyone noticed the same issue when you turn off internet sharing and then try to connect to any Wi-Fi? ughhh it constantly gives me errors such as No Internet Connection detected and an exclamation mark on the Wi-Fi icon!!!!

Hi! For me the answer was - and remains, as I've just tried again without it and the connection dropped immediately - something I found on the OSXDaily site (http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/). This is a simple and, I've found, extremely effective workaround until the problem is fixed, which it wasn't in the 10.7.1 upgrade. Give it a try!

Another Idea: Maintaining Data Transfer

Another theory is that when data transfer stops, the wireless connection inappropriately drops. You can avoid that by simply launching the Terminal and pinging a random address, this causes a miniscule amount of data transfer to occur and that can be enough to maintain an active network connection.

• Launch Terminal (accessed at /Applications/Utilities/Terminal or by using Spotlight)
• Type “ping yahoo.com” at the command line and you will see something like this

• ping yahoo.com
  64 bytes from 98.137.149.56: icmp_seq=91 ttl=52 time=27.806 ms
  64 bytes from 98.137.149.56: icmp_seq=92 ttl=52 time=27.763 ms
  64 bytes from 98.137.149.56: icmp_seq=91 ttl=52 time=27.806 ms
  64 bytes from 98.137.149.56: icmp_seq=92 ttl=52 time=27.763 ms

• Just let that run in the background, it isn’t resource intensive

Hey, no disrespect intended but...why the heck would I want to execute a script of constant pings? All I need to do is select another AP...or select the same AP again after the machine wakes.

HEY APPLE...107.1 didn't fix the problem!

I'm glad I found this thread. The 10.7.1 update has done naff-all to fix my wifi dropping after a sleep issue. Glad I'm not alone; it's doing my nut in!

Has anyone noticed that they didn't have the problem re-connecting to wi-fi with 10.7 and then when the update (that was supposed to fix this) all of the sudden it started happening to them? This happened with me and it's ******* me off! It worked fine befoer the update and now every 3rd or 4th time I awake from sleep it won't connect to my wi-fi!

Oh now THAT would "inhale deeply"!

I'm going to try to remove all my network connections again and then re-create them after re-boot. I'll let this thread know the outcome but I'm honestly not hopefull of a correction.

HEY...anybody reading this...PLEASE be sure to create a ticket with Apple Support...they need to know it's still a problem.

Thanks

I had problems with the Macbook Pro wifi after sleeping, and Virgin Media eventually suggested changing the wireless router to a Dlink router. This solved the problem immediatley.

Interesting situation for me...

After waking I do not have the problem every time (after deleting & re-adding the networks). When I do have a problem I found that if I refresh the page...the connection appears to work and I can browse just fine.

The connection is NOT working consistently however as proven by my email not automatically downloading any new mail.

I'm sorry but I expected more from Apple on this one....

I have noticed that if Time Machine is running it hangs and doesn't re-connect. If TM is off or stopped, it looks like it reconnects as it used to. I'm not sure if this is a real association, or whether it's a coincidence.
