Mac OS X Lion WiFi issues

Ever since I have upgraded my late 2009-iMac to Mac OS X Lion 10.7 I have been experiencing issues regarding my WiFi. I'm actually loosing connectivity, as in AirPort seems to keep "refreshing itself" for no apparent reason, and disconnecting my WiFi intermittently each time. It's almost like my WiFi card can't keep a stable connection to my router anymore. This problem is not occuring on my iPhone, which is also connected to the same home network on the N Router. It's constantly halting downloads halfway through, or near to the end, and they have to be restarted and this is infuriating when the download has taken ages!


Even reaching this page now took several refreshes, as Safari keeps coming up with blank pages every now and then telling me I am not connected to the internet.


Has anybody else had problems with Lion dropping WiFi connection constantly?

iMac, Mac OS X (10.7)

I have a late 2009 iMac i7 on an AirPort Extreme network, and my connection will drop every 30 seconds or so for a few minutes at a time, at random times throughout the day. No other devices do this. Sat through firmware update, software update, with no fix. Makes it seem like the only fix will be with Mountain Lion, which I feel like I shouldnt buy, as I have been dealing with this issue ever since I bought the last OS!

I am thinking it is (not your computer per say) but rather how you have everthing set up. You have multiple local wifi networks being created at your home/ office and you have some sharing channel 1, and some using wpa, wep, and then you have some using N and some using G. And I am not sure, you said you were using an Airport Extreme? Are you using your Airport Extreme to connect to another network (such as 2WIRE915) - I am not clear on your setup. And I have the same Atheros wifi chip as you so good chances it is not the chip, and I have Lion, so chances are its not that either. This is what mine looks like. I have one network, but I have two routers - the primary router is a time capsule, the secondary router is an Airport Extreme which extends the primary network. You can also see my transmit rates are pretty good.


This is mine for my imac... ( I have no problems).

Dear bb007,


So sorry you are having this issue, join the club. To my knowledge, there is no universal fix. If you page through the thread, you may find some temporary ones, but basically, Lion and wifi are NOT FRIENDS. It's a shame. Many have downgraded to the previous version of the OS because of this issue. If you have a new computer that came with Lion pre-installed, that probably isn't an option for you, I'm sorry. DOES ANYONE KNOW OF A NEW FIX THAT I'M UNAWARE OF? (I've tried a dozen from this thread - thanks for trying to help, everyone.)


Please just ignore Carlos' sniping remarks on this thread, which make you feel as if YOU are the problem. You are not. This is a ridiculous glitch with Lion which for months and months has gone UNADDRESSED by Apple. Shame on you, Apple, for not paying attention to this issue, and for the robot-like mentality you apparently instruct your AppleCare "customer service reps" to exhibit. Especially Carlos (who is either an Apple rep or has drunk some serious Apple KoolAid), who continues to post unhelpful comments and suggestions here, such as "it's your wireless phone," or "I have the same computer, so it must be your settings."


LION IS CAUSING THIS ISSUE, and it has not been resolved or addressed by Apple for many months. It is a shame that many longtime loyal Apple customers such as myself are being ignored on this issue and made to feel as if we are the problem. It is losing Apple customers, and frankly, I've advised friends NOT to upgrade to Lion or purchase it with an Apple product until this issue is resolved. For people who rely on wifi daily, it is more than an inconvenience, it is a dealbreaker.


We expect more from Apple. And, Carlos, please, if you can't say something actually helpful, please just stop? Newbies to this thread don't need to be sent on a wild goose chase. Unless you have an actual FIX, please stop.


Thank you.
