Q: Wifi Constantly Dropping in Lion

Verizon Fios Actiontec router users only!

This is something that has been working for me since early Saturday.

I've passed it onto Apple.  I know most of us has tried deleting our network setups with no luck.

Well this is what i did:

1: Deleted all networks and setting on my Mac again.

2: This time after that I did a Hard Reset of my router.

3: Rebooted my Mac

4: I then let our 2 Macs and Router set them selves up Automatically.

5: I left all settings to the default  settings including Network name

6: Later I set my energy settings to deep sleep every 5 minutes.

This morning I decided to update my Onkyo receiver.  I disconnected my router and moved it over to the receiver it needed to be hard wire connected to the receiver.  The net worked fine there and when I put it back in the other room and connected to my PC every thing was still working wirelessly on our Macs.

I intentionally waited 2 days before I posted this and 36hrs before I passed it onto Apple.

I really don't know if this is just a fluke or if it works on other routers.

If you try it let me know your results.  I'll pass it onto Apple.

I've been dealing with the problem of my wifi dropping for several months now on my iMac and MacBook Air.  Like a charm, every 5 minutes it would drop like a charm - iPhone, iPad and PCs connected without a problem.  I've been following this thread for months now.  I eventually reinstalled Snow Leopard on my iMac which took care of the problem on that machine.  However, because my MacBook Air came with Lion and could not be downgraded to Snow Leopard it has been a door stop till this weekend.  I used Boot Camp Assistant to install Windows 7 Pro and have been succesfully connected to my network without drop for several days now.

This tells us what we pretty much already know - not a hardward issue....has to be something in Lion.  I haven't installed Mountain Lion yet but probably will soon.  Just wanted to chime in that the MacBook Air has no connection issues when running Windows 7 in Bootcamp.

Shhh!! .... You'll wake Mr Wi-Fi interference.

Troubleshooting Wi-Fi issues in OS X Lion

Do you like giving links to useless things?

Well it makes 3 days now and no dropping wifi. 

Mac 101

I did nothing to my ML's setting.

I went into my DIR-615 router. Changed the security mode to "Enable WPA2 only" instead of "Enable WPA2/WPA".

ML still disconnects when sleep, but will connect quickly after waking.

Add me to the list - must be MacBook Pro related - new MBP 10,1 (OSX 10.8) Wifi connection dropping and reconnecting same as old MBP...

Thank you thank you thank you!!!

Finally got rid of the disconnections!!!

If I ever run into you in real life drinks are on me

I've stated this several times before - it's Lion, but it may not be a software bug in Lion.

The example I cite is imagine the router has a firmware bug where it calculates "2 + 3" as "5" but "3 + 2" as 6.

It's not the responsibility of Apple to work around the broken router and always make sure it only adds "2 + 3," but if Windows does nothing but add "2 + 3" then Apple gets blamed for having a "bug" when it's the router that's at fault.  (The "It works under Windows!" fallacy.)

This does not mean it's not a Lion bug - it certainly could be - but rather that your experience does not necessarily prove that it is.

Something is wrong here!   Every thing I write , disappears immediately

Final Fix..

Downgrade the kext/driver of wifi to snow leopard version kext.

Well, this can work, because it allows your mac to ignore the errors that your wireless modem, or ISPs DNS/connection has.  There has been a demonstration of the cause being related to dropped packets which make other devices seem "slow".  A couple of people have switched just ISPs and fixed the problem, so you might want to do some more investigation of the cause of your specific issues to see if other people using the same ISP in your "area" have the same problem.  In other words, if you have friends with the same ISP, go see if you have the same problem on their network.  If you have friends with another ISP, or a coffee shop or something that you know is using a different service, see if you have the problem there.

Talk to your ISP if you can determine that you only have the problem with that ISP.  One person reported that their ISP's technical team said that their network had a lot of packet loss, and this was causing DNS over UDP to be very unreliable and other things related to Apple's new network security measures instituted in Lion, to create "you are not connected to the internet" messages.

In particular, this person had the same router as a friend who was on a different ISP, in the same building.  He litterally went to the basement, and switched phone lines at the punch down board so that he was using his friends phone services and thus DSL service.  Suddenly, he had no more problems. 

There are lots of diffferent experiences people are having, but suddenly, it really seems that Apple may be relying on an advanced network feature or behavior which not all networks can provide, reliably.

Thank you gphnei. I was one of those guys but all our postes are deleted here. It seems something is going wrong. I am reposting that in a new thread.
