Comments on: WiFi Dropping in OS X Lion? Here are Some Wireless Troubleshooting Solutions http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/ News, tips, software, reviews, and more for Mac OS X, iPhone, iPad Sun, 19 May 2013 22:41:36 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: Richard http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/#comment-523350 Richard Sun, 17 Mar 2013 11:01:09 +0000 http://osxdaily.com/?p=19133#comment-523350 I commented earlier about this issue - see http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/#comment-420287 My fix mentioned there was to install an older WiFi driver - however this didn't in fact work in longer term, as the problem recurred. The real fix was to use a different WAP - I only seemed to have this issue with an Asus RT-N10 access point, so I'm now using some Solwise HomePlugs with WiFi, and they are 100% reliable. Still using the older WiFi driver but will get rid of that so I can do OS X updates.

My wi-fi kept dropping since upgrading to 10.7. In my case, it turns out to have everything to do with that beloved old router. Not only did my iMac drop, so did my other devices. And when it WAS connected, my Charter cable internet was being choked down to ~8Mbps over the wi-fi. Yesterday I bought and installed a D-Link dual band Wireless-N router. Problem solved. No more drops. Also, my online speeds picked way up across all devices, clocking upwards of 30Mbps. And no wi-fi dropouts. For everyone else with this problem, what brand and type of router are you using? I was using an old Cisco Linksys Wireless WRT54G. My wi-fi kept dropping since upgrading to 10.7.

Apple TV is running in my house as well. Tonight I figured out, that the last update of the AppleTV fixed the problem!!! So it was not the iMac but the old version of AppleTV causing the problem. Good luck! Andrea Hi everybody

The idea is to make sure that the security method matches that of the wifi. * Go to Network Preferences > advanced > Wi-Fi and delete your wifi by selecting it and pressing the "-" sign. * Press the "+" to add a new wifi. * Type the name of your wifi (do it manually, please) Now the most important step: * Choose the security method that matches your wifi settings (Check your wifi settings if not sure). * Type your password (if applicable) * Press OK, OK, Apply and you are done. I hope this helps someone out there. You might want to add this to the above trouble shooting tips – it worked for me.

The idea is to make sure that the security method matches that of the wifi.

* Go to Network Preferences > advanced > Wi-Fi and delete your wifi by selecting it and pressing the “-” sign.
* Press the “+” to add a new wifi.
* Type the name of your wifi (do it manually, please)
Now the most important step:
* Choose the security method that matches your wifi settings (Check your wifi settings if not sure).
* Type your password (if applicable)
* Press OK, OK, Apply and you are done.

I hope this helps someone out there.

Finally I found a solution! I had been getting my IP address dynamically from my ISP. I switched my router settings to use a static IP address. Problem solved.

Note that it works with Broadcom as well as Atheros, despite the atheros in the zip filename! I'm on a Macbook Air mid-2011 13" with Lion 10.7.4, which uses Broadcom 43xx according to system_profile. I have had the problem for weeks, including very poor latency (10 to 40 sec sometimes), many lost packets, and of course failing to reconnect after sleep. Tried various solutions (removing plists etc) but this is the only thing that worked. WiFi is now working fine for last 24 hours and no dropped packets, latency to my WiFi access point is just 3ms as it should be, after 1000s of packets. Edited version of the Kext Utility output when installing this driver (kext) - note both Atheros and Broadcom modules are installed. Also in my case it updated the Broadcom device firmware (not shown): ProductName : Mac OS X ProductVersion: 10.7.4 BuildVersion: 11E53 Kernel : Darwin Kernel Version 11.4.0: Mon Apr 9 19:32:15 PDT 2012 Model ID : MacBookAir4,2 KernelMode: x86_64 Detected ...

My problem was fixed by removing my wifi connection and then adding it again. But instead of entering the information manually, I selected it from the list of available networks and realized I had WEP instead of WPA2 Personal which is what is actually was. That may have been the issue, but now I don't have to manually select the wifi from sleep, now it works, thanks to this site!

My mac is the only machine with a reservation so the PCs and xbox can randomly choose anything between .100 and .149. Doing any of that crap in network/system pref just fixes the prob for a day if your lucky, a minute if you are most people. I tried everything and this has actually seemed to work.
