Wifi Constantly Dropping in Lion

moskovit, have you tried unhiding your network ? Closed Network really does not provide any real security.

wifiguru, thanks for your reply. Why do you say that a closed network does not provide any real security? Doesn't it require that a user know the SSID to even know it exists, let alone log on, providing one more layer of security?

Because anyone with a sniffer can easily find out your network name. It is really pointless to hide it. Infact sometimes since other client's won't show this in their scan list (based on wireless driver behavior), you might end up being bad neighbor. Leave it unhidden and use WPA2-PSK as your security to actually secure the network.

A lot of people say this, but it's like saying because a professional would either pick your lock or just smash a window, there's no point in locking your doors.

The idea is to make your network less visible to others and preferably for others not to even know it's there so that casual baddies move on to a different, more obvious network; it's not to dissuade the more talented/well equipped folks who would have sniffers and such.

Yup, I'm just "me too-ing" this post. Wi-Fi connection drops are rampant on my brand new 27" iMac Core i7, I've had WPA set-up for years, and I'm all Apple from this side of the cable modem. It's definitely a Lion thing, and 10.7.1 didn't fix it.

my statement of 'wifi dropping' isnt that accurate, what is happening with mine is that my iMac is staying connected to the router but any programs using the net (mail, safari, skype etc) fail to connect online. My only solution (and I've tried all the various suggestions on here) is too turn the wifi off then back on.

Is this the same issue as everyone else or are you losing the router connection?

My situation is exactly the same, Shaunmull. The 7.1 upgrade has helped a little, but I still have to turn wifi off and on at least once during the day. I'm not interested in trying any of the various workarounds, though I admire the ingenuity they represent. This is an Apple bug and they should fix it, and I believe they will.

@shaunmull, my issue was the same as you're reporting. 10.7.1 fixed the issue for me (so far).

mine was dropping multiple times a day, as infrequent as every 5 hours, and as often as every 10 minutes.

until they come out with 10.7.2 to fix additional issues that are still present, i'd go thru the various recommendations on this board and see if they help.

I everbody. Done everything posted in this forum. After "upgrading" to Lion my WiFi is simply gone. Completely unable to join any network. Dead, dead, dead...

I have been trying to recover my WiFi for too many days already. My girlfriends SL macbook works wonderfuly. My iPad and iPhone as well. All on the same router.

I'm going to backup everything again and "upgrade to Snow Leopard"

MacBook Alum.

Cheers!

Could someone please list what has been suggested thus far on this list? I'm afraid I don't have time to read through 493 messages, and would appreciate some help.

Hi!

I have MB Air with preinstalled Lion. My Wi Fi connection is not stable (softly speaking). 7.1 update didn`t fix the problem.

at the beggining you will find methods and links to fix the Wi Fi problem.

Only it is not the solution, it is a bug that should be fixed by Apple

I was able to fix my Wi-Fi in 10.7.1 by "disabiling" IPV6. Try changing Wi-Fi to "Link-Local" from "Automatic" on the Wi-Fi adapter. Would appreciate knowing if this helps others...

Didn`t work in my case. MBA os x Lion

That was one of the first things I tried. Didn't help.

What I've done is to start using a USB wifi adapter. Very inconvenient, but effective.
