****Fix for Lion WiFi issues!!!!!*****

When this happens to any one are you able to see any other networks around you that you could see before, I know I can't? I also tried channels 1, 6, 7, 9, 11 with no luck.

I have to say that as far as I'm concerned my router and settings are fine. My closest neighbors networks usually show up when they're on line. They have different routers and ISP's so it's my mac and ML.

If I haven't said it here my wife's mac has never had the issue even with Lion.

I never used to have any problem with my wifi even with Lion on my macbook air 13". However as time went on I found that my mac took more and more time to boot. I searched for a solution and found that by clearing the P Ram (holding option + command + P + R during boot) it would make a faster boot. Now my mac is quicker booting but since I have done this, wifi is constantly dropping. Strange coincidence !

Anybody has an idea as to why ?

I had my linksystem E2000 router set on cahnnel 6 and the wifi kept dropping. I'm trying channel 4 now and will see what happens. It doesn't make any sense to me though. The wifi drops everywhere I go. At my university, at my friends place, and at home. Furthermore, the wifi is doing drops the same way on bootcamp. This leads me to belive the problem is in the router driver software.

Anyideas?

Cheers

I use an air port express and have this problem. Is it possible to select channels on an air port?

My computer is doing this too. I have a Macbook Pro 2011- running with Lion. It just started with me a few days ago. I called Apple Care they acted like I was the only one with this issue. Of course when I was talking to them my wifi was up. They had me do a PRAM reset or something, and it is totally useless. My Wii, and iPhone are working fine, as well as my iMac. So I know it is something with Lion. Ugh- can someone put a solution in laymans terms? I don't understand any of these solutions.

I had the connection timeout pop-up message and was going crazy UNTIL I changed the channel on the Airport Extreme from Automatic to Channel 4--worked like a charm. Thank god for this quoted post:

Hello all,

I have just got off the phone from Apple, and my ISP about these issues we are having with Lion dropping its WiFi connection all the time. Apparently its to do with the channel your wireless router is transmitting on. The guy at Apple said that of the 12, apple products are made to work with 4. These are Channel 6, and Channel 11. I forget the other two. The way to fix it is to go into your router and change the channel from Auto (as mine was on) and set it so that it broadcasts on one of those channels. Its been an hour now and i havent had my WiFi drop out once.

If you dont know how to change your channel, do what i did. I phoned my ISP and asked, they talked me though it and now everything is working great!!!! Fingers crossed anyway!

Good luck

I am not sure how you change the channel on Airport Express but I am sure that the utility like Airport Utility.app should do the trick.

I had the same problem both with Lion and Mountain Lion, and nothing seemed to help. I changed from my AirPort Extreme (the flat one) to AirPort Express (the older, cone-shaped one) and have not had the problem since.

this did not work for me 😟

Yes, Changing to Channel 11 on a UK BT Home Hub 3 worked for me

I've a 2009 MacBook running Mavericks.

Speed of WiFi network also 10x faster. I'm now on 4Mbps instead of 0.35Mbps.

Very pleased :-)

It took me several days to figure out what was going on, especially since the demon console was spawning so many different messages that led me (literally and intentionally led me) on a WILD GOOSE CHASE, before I finally realized that the most dropouts happened when my 18 year old was home using his laptop and yelled rather loudly for him to bring his laptop to me. I compared his console messages to all the other 5 laptops in the house and lo and behold I had a little torrenting problem on my hands. That little scoundrel was seeding torrents. Once I realized what the problem was, I went back through my console and started reading the messages very closely and saw all the engineer humor at work. Now we were warned months back and I thought it had stopped and so did he, but apparently he had some other stuff in the torrenting software that was legit to use and whenever he opened it, it would start seeding something that wasn't. I was getting messages like these,

doAutoJoin: Already associated to “...”. Bailing on auto-join..

"Bluetooth Coex: In 2.4 GHz, bandwidth of 0 is under low water mark of 5".

"__AirPortOpportunisticRoamTriggerRSSI:"

"roam event, sending supplicant link down message".

But here is the gem tucked in among tens of thousands of messages:

parentalcontrolsd[22288]: StartObservingFSEvents [849:] (Ohhh start observing File Sharing Events!)

and then this one:

block_invoke

So there is nothing wrong with my computer after all, and so long as the computer with the torrent on it is not on the network, I have zero wi-fi drop offs, as soon as it is on, all you know what breaks loose.

Parental Controls have now been implemented!!
