Wifi Constantly Dropping in Lion

Since upgrading my Fall 2009 21.5" iMac to Lion my wifi connection will drop out about every minute and the I have to turn Wifi off and then back on to get it to connect again. Is there any known way to fix this? Any suggestions will be appreciated


Thanks

iMac, Mac OS X (10.7)

My original problem was wifi dropping after computer was awaken from sleep, requiring me to turn wifi on, then off to restore the connection. Update 10.7.1 did the trick, no drops since installing the update. I would suggest that many of the posts be a bit more specific about their particular problem and what equipment they are using, hopefully there will be a fix soon that will help you.


MacBook Pro 17 Dual Core I7 Lion 10.7.1

Airport Extreme version 7.5.2

I am glad things are working out so well for so many of you. I thought the .1 release had fixed my problem. I was on for a night and much of a day before mine dropped again. Today it has been awful. I just spent the past 1.5 hours trying to get my 27" iMac back online. I booted the older iMac into Windows to get onto the Internet, and I'm wondering if logging on wirelessly through Windows caused enough tumblers to fall into place in the world of the wireless to allow me to log on using my new 27" iMac. Whatever it is I do that finally manages to get me on feels like I'm trying to invoke the favorable attention of deities through ritual and dance. I don't know how or why it happens, but eventually something I do gains their favor and I'm on again--at least for awhile. Or perhaps I'm merely assuming that getting back in is a result of something I do. Maybe it's inner workings of my computer and router that are unrelated to my activities that cause it. Who knows.


When I can get into my router--I tried awhile ago and was unable to--I will even switch my router to broadcast on Channel 3 and see if that stablizes things for me as it has with others.


This is insane, folks. I never thought I would experience these kinds of problems while using a Mac.

Just spent a good hour on the phone with Mac support trying to fix this ugly, ugly problem after trying most of the sensible suggestions in here. Nothing.


Apparently the only solution I have is to wait for 10.7.2 update, even though the nice guy on the phone could not give me a ball park date. Alternatively, I was told to buy a 30-ft long ethernet cable, keep the receipt and return it when apple fix the glitch.


I never, ever thought I would experience this frustration with apple.

I hate to say this, but don't bank on the Ethernet cable working for you either. When my wireless doesn't work, my Ethernet doesn't work. Both are either working or not simultaneously, but only in Lion. On the Mac with Windows on it (which connects only wirelessly) I can always get online wirelessly through Windows XP, as is true of an old PC laptop. The problem is with Lion, and apparently the gurus that be don't have a clue how to solve the problem. Apple's apparent disregard for the urgency of this matter for some folks and its dogmatic determination to address issues only through dot-digit releases rather through emergent patches is alarming to me as well.


When I'm freeling really brave I will go into my router and change it so that it broadcasts over Channel 3. That seems to have worked for some folks. For now, I'm burned out. I have maintained a connection for two or three hours now, so I'm leaving well enough alone for the time being.


P.S. I just lost my connection again as I was trying to post the above. Only spent 4 minutes trying to get back on.

Hi,


I was having the same problems with MacBook Pro and iMac after upgrading to Lion. I called Apple and what the tech ran me through has now worked for 24 hours with no issues with my Airport Extreme and both my Macs. This includes in and out of sleep, start ups, constant connections, downloads, etc. NOTE: I am running a Windows machine that suffered the same issues so in my case, these seems to clearly be a router issue. This may or may not work on on other routers than the Airport Extreme and only those people using an Apple OS (so you can access the Utility Folder in Applications).


1. Unplug the router

2. While holding the reset button down with a peper clip end plug it back in until the front light is solid orange.

3. When it starts blinking orange, open up Airport Utility in the Utility folder in applications.

4. Completely re-setup your router, choosing WPA2 for security. You can name the router whatever you want.

5. Wait for setup to complete.

6. Link your computer to the new network.


One other thing, if that still doesn't work, Apple told me to look at your avaialble networks to see if there are a lot avaialble. If so, you may be getting some interference from one of the other networks. Apple suggested changing the from Automatic to enter your channel manually, and try random channels until you see fewer or no more other networks other than yours. to do this, go back into Applications>Utilities>Airport Utlity>YOUR ROUTER>Manual Setup. Then navigate to the Wirless tab and switch from Automatic to selecting a different channel. I did this and it seems to have worked for me. Hopefully these steps might work for others.

Well, tried this solution: Go to System Preferences > Network > Create a new location in the dropdown menu (any name will do) > restart computer.


Didn't work. Next day it dropped the signal again. In my case, it is pretty easy to get the signal back; I just turn off WiFi and turn it back on. But it is a nuisance.


I really think all the solutions on these boards are a waste of time (no disrespect to those who suggested them). We can reset PRAM and SCM and rename this and that all day long, but until Apple fixes the problem in the OS, it will persist.

Indeed. A proper solution to this wifi debacle has to be given. Do try changing your wifi channel from automatic to channel 3 so as not to suffer from constant frustration.


We must insist on having this issue worked out. People can't go around with their macs asking for people to change their routers channels to 3 or 4 everywhere we go. Basically our machines are now locked to the wifi routers we can modify, can't access public wifi networks at uni, libraries, at clients offices or anywhere for that matter since the signal keeps dropping.


Apple basically turned our portables into desktop machines. Completely unacceptable.
