It'd stop working and I have to turn it off and on in settings before it works again. Apple told me to reset the router which I did, and I also tried to reset the network settings to no avail. Anyone experiencing this issue?

This is a known bug and was supposed to be fixed with the last update 10.7.3. Hopefully it will be fixed next release. It happens to me all the time. I just click on the wifi icon and wait for mine to show up again and click on it.

I think this is in the wrong forum. You are asking about Lion? I had this issue when I got my new iMac in late 2011. The dropouts started as infrequent and literally worked there way up to every minute. There are a bunch of threads, a few of them literally 100's of pages long, about this problem on the Apple Support forums. A lot of people's troubles got WORSE when they used the 10.7.3 update. I guess not many people have the issue on this forum because I don't hear a ton about it. But it was a nightmare for me. I have a 6 other devices running different OS's that have no issue with my network. The machine running Lion is the only one.

Through trying out dozens of tips in those threads on the Apple Support forums I was able to 'fix' the problem. I don't get any dropouts now. But, I don't even know what finally fixed it. And I am afraid to do any OS update in case it breaks again. Which is what happend to a lot of people who had things fixed, then had the problems start all over again with the 10.7.3 update.

This problem has been a nightmare. I spent days working on it. The majority of people in those threads haven't been able to get any fixes to work.

About the only other input I can give is that quite a few people have had some success replacing the WiFi firmware with a version from Snow Leopard. If you feel like reading ONE of the threads with over 100 pages of posts: https://discussions.apple.com/thread/3190651?start=15&tstart=0

The is not a drop out issue the OP is talking about the issue is the wifi is gone when waking up the system from sleep. Though it is not to say that the issue is from the wifi firmware as this only started happening when I upgraded to lion.

I have never encountered a drop out while using the computer so my thinking it could be something else in play.

What I was saying is that is how the issue started for me. And for a lot of other people in the support threads. Then it elevated to constant WiFi drops.

The first thought in all of those support threads is that something else was in play as well. Until they grew to be 100's of pages long with more people joining them every day. The action has actually increased in those threads, not decreased. Not everyone is having the problem of course, but a ton of people are. There has been no common thread found amongst router types etc. People in the threads networks function completely fine, except with their Lion machines.

Anyway, wasn't trying to rant. Just point out that there is a ton of info about ALL wifi dropping issues in the threads on the apple support forums. The obvious answer is to make sure you applied the fix that Apple released. But, if you check those threads you can see it didn't solve the 'wake from sleep' issue for a lot of people.

My wi-fi in Lion has OCCASIONAL trouble re-finding the network when waking from sleep. I leave it alone for a minute and it eventually works it out.

You might try going into the network preferences and deleting all the networks listed there except for your own, that might help.

I'd prefer if it worked more like the iPad and iPhone, which NEVER fail to instantly connect to the network on wake, but it's not so much of an issue or happens so often that I'm bothered by it. Just occasionally happens.

I had about 5 or 6 of these events over about 3-4 months, fixed just by turning wifi off then on, but none sine the last wifi update. Mid-2011 iMac.

I had this issue at a hotel I stayed at recently, though I have not experienced it at home. While I recognize this is not a solution, I hope it helps to finding one.

What helps? Confused here. :confused:

This is why people are in an uproar on the support forums. Most people including myself have many other devices running on their network. I have never had an issue with a single other device other than the one machine I have running Lion.

As mentioned, it's not a problem everyone is having. But when you have it, man does it suck.

Different routers; different behaviour. May not be entirely an OS X issue, but related to other hardware.
