Q: Lion WiFi Connection Problem

ok im on a complexed network with windows server 2008 yes its windows but ok this is tagging along with similar mac issues i am using my mac via WIFI IF I USE WITH NORMAL JUST WIFI NOTHING WORKS STORE MAC UPDATER AND SAFARI THAT IM CURRENTLY USING ATM OVER WIFI

I had to use a vpn into my server yes a VPN connection that i never had to do and im thinking what the h to the f  never needed to use vpn only when im out side my network and  and to spannerdarl i have the auto proxy discovery enabled didnt do anything

so a summary 

using macbook

wifi on and using the 5 g net and yes tried the 2.4 g  nothing worked safari mac updater and i believe also msn oh and skype works yes this is odd

to get it all working used my own VPN  everything came back to life all programs worked mac updater mac app store  everything including msn

they messed up a setting some where / codeing is missing or wrong

OK, here’s another data point.

Yesterday, I went back again to the Buffalo Air Station site where I first had problems connecting after a Lion upgrade install but that were solved by a clean install (disk partition/format) of Lion.

I had no problem making the initial connection and things seemed good and fast at first but during the course of a 4-hour session, I was getting times where facebook and google would not come up in any browser and email could not be received/sent. Leaving the connection for a few minutes and then trying again would sometimes fix it. Switching wifi on and off sometimes would and sometimes wouldn’t although the connection bar was always showing full strength.

I captured the whole session on wireshark again and sent it to Apple Bug Reporter like last week.  Nothing back from them but they cannot be ignoring this issue–there are too many youtube videos and other reports showing the problems.

Just have to wait for 10.7.1 I suppose.

I’m amazed at the cone of silence from the well-known pundits like Gruber, Ihnatko, and others.

ok i did a step you may have the auto pproxy discovery enabled in wifi

click wifi and go advanced then go to the proxies page and uncheck the auto proxy descovery  i guess this is the resolution 

like it if it works for you

i also did another step turn off my time capsual i bet this did absoluly nothing  but give this a go

the tech  guy on phone told me today

Here is a workaround I that worked for me:

Make sure therer is a constant network traffic, for example just leave your favourite torrent client running.

It was running whole night and in the morning I was still connected

Same experience, there is a real problem with Lion and wi-fi.  I hope the engineers are working on it or I will have to go back to my Windows machine!

Hi to all,

after reading all the posts, it seems the very most of you have dropping / slow connection issues while the reception is still o.k. My problem is, that my mac mini can't even see available networks.

This is my story:

I bought a new C2D mac mini, shipped with SL 10.6.4 which worked perfect for a couple of weeks.

After I updated to 10.6.8 the wi-fi was gone (downloaded the online update, installed it, reboot -> wi-fi gone).

The hardware is shown as still present but can't see any wireless network even though three different are there with five Windows7 notebooks connected. Tried everything to no avail.

--Went back to 10.6.4 -> reboot ->wi-fi o.k.

--Updated up to 10.6.7 -> wi-fi o.k.

--Updated to 10.6.8 -> wi-fi gone

--went back to to 10.6.7 -> wi-fi o.k.

--Installed Lion -> wi-fi gone.

All updates where done by keeping all documents and preferences (no clean install).

After three days offline under Lion (including some cold starts) suddendly wi-fi came back again and worked perfect. Yesterday I downloaded the trial version of Adobe CS5, installed it reboot and... guess what ...wi-fi gone.

The next step is to uninstall CS5 and see what happens. This is my first Mac, so I'm kinda helpless...

Just adding another of the same:

2011 iMac.  No problems with wi-fi on Snow Leopard.  Installed Lion and the wi-fi connection keeps getting dropped.  Wi-fi signal is stable with other computers in the house running Snow Leopard. 

I have had this problem of Lion dropping my WiFi connection at random since installing the OS on my 27inch iMac.  Strangely it does not affect either my 15inch MacBook Pro nor my 13inch MacBook Air both now running Lion.  The only difference is that with the 27inch iMac I reacted to a prompt to install Java Runtime without really thinking and with many Apps still open including possibly a web browser (Chrome.)  On the laptops I installed Java Runtime very carefully from Apple's site with all Apps shutdown.  I thought removing Java Runtime and reinstalling it carefully had cured the loss of WiFi - but NO!  I now run the 27inch iMac directly off a LAN cable since the router is right next to the computer.  This seems to be the only cure.  I suggest there is a very real problem that Apple needs to invesigate and resolve.

i just tried this one but it doesn't work for me....

some apple guy come out to figure out the problem, please

Hi.

Same problem for me

iMac27 late 2009 i5 12 Gb.

Waiting for a solution from Apple.

I should update also my MacBookPro: Do I get the same probme also on it?

I also have the same problem since I've updated Lion... When will be available the first update to solve the problem???

Running MBP, just upgraded to Lion a few days ago... My wifi shows I'm connected, but it will not load any web pages. I tried to delete the network and reenter the data for the connection (network name, PW, etc) still will not load any pages. Did not have this problem before the upgrade. Also, my Keychain Access quit working from the dock, I removed it from the dock and added it again, now it is working, in case any of you had the same problem. I hope someone can give me an idea on where to go from here?

L.I.O.N = Lousy Internet On Network or Lack Internet On Network

Please Apple - hurry up with the 10.7.1 fix

To settle once and for all that it isn't my hardware I installed Windows 7 via Bootamp and lo and behold, I haven't had an issue all day with wifi. It's safe to say I'm going to keep using Windows on my expensive paperweight (mid 2010 MBP) until 10.7.2 comes out. This is ridiculous...I reset my router to factory settings before last weekend and it worked again for a day or 2, then last night it decided to completely stop connecting to anything, including my personal hotspot on my iPhone, again. Windows had no problem connecting on the first try.
