New MacBook Pro & Leopard - Airport Connection problems

it says solved but so so isnt.
if youre having this trouble and get to this thread n.b. apple hasnt fixed it. doesnt seem to plan to fix it. doesnt seem to acknowledge its a problem.

I was having the same problems, i tried every thing, i changed my encryption from WPA to WEP to just NO encryption and nothing worked, i would use the assistant and it would not help

Here is What did Work:

remove the power source both the battery and the cable (for imac just unplug the power), hold the power button for 10 seconds put the battery back in and plug the power back in as well press and hold (hold for about 5 seconds)the power button untill the indicator light flashes repeatedly let go of the power button after the light flashes and you should hear a continuous beep and then the computer will boot up. now it sould be fixed.

I finally called Verizon and got walked through upgrading the firmware for my Westell Versalink 327W, and now I can see my signal fine and so far not getting bumped off. Of course, not using any security so I don't know how relevant my fix is for anyone else.

I suggest contacting your provider and have them walk you through the upgrade process, but the basic steps for me were:

going to http://gonow.page.tl/ and downloading a Westell upgrade

going to http://192.168.1.1/ and walking through the setup process there, and when it came time for the software upgrade, I uploaded the .upg file that I had just downloaded from the previous page.

Also my stepson has been connecting fine using Leopard with a Netgear router.

I've experienced two problems with my wireless connection: both the issue where the computer does not reconnect after waking from sleep, and dropped connections even during an otherwise successful session. Here's what I've found fixed the problems:

For the not-reconnecting-after-sleep issue, deleting the Library/Preferences/SystemConfiguration folder, removing all Airport Keychain items, and rebuilding the network settings seems to work. I also made sure to change the permissions on the Keychain item for my network (after setting it up again) so that all applications can access it.

For the connection dropping issue, I tried a number of things, but eventually found that using a NetGear WGR614 router fixed the problems. I had previously tried basic 802.11g routers from Linksys, Belkin, and D-Link without much success.

No guarantee that any of this will solve your problems, but I spend a long time reading these threads, and figured that I should add my experience.

Some details on my setup:
802.11g network, WPA-TKIP security
Computers: Core 2 Duo 15" MacBook Pro, Early model MacBook
OS: All running 10.5.2
It's in a small apartment so range isn't an issue, but anywhere from 5 - 10 other wireless networks may be visible at a time. I think that some of the problems might have come from the high amounts of 2.4 GHz WiFi traffic.

Howdy, folks!

I just wanted to chime in with my experience, here. I bought my MBP late last year to replace my old PB, it came with tiger installed and drop-in disks for leopard. Migrating everything from the PB to the MBP went flawlessly, and the MBP would connect to my home airport network just fine. After I used the included leopard disks, it started having the "will not connect to wireless network when it wakes up" problem, which I work around by just picking the connection when I wake the machine.

I know it isn't a problem with the network, as this same MBP connected fine under tiger, and it also connects fine under windows. I don't want to open up the network (it uses a 128 bit WEP password, right now), nor do I want to restrict it to g only (my mother-in-law lives with us, and connects to the network from her b-only Pismo). Between all of us in the house, we connect to it with various ibooks, powerbooks, macbooks, my MBP, and various linux and windows machines (we're a big, connected family), so I'd rather not muck with router settings and make everyone else change things on their machines.

I've tried various solutions from this thread, with no joy. Right now it's not a huge deal to me - I just have to pick the network manually when I wake the machine, so I'm just waiting for a fix from apple.

Problem solved!

For me, doing a full archive & reinstall took care of the problem. Seems like there's something that doesn't get set up properly in an upgrade scenario...

Hey all,

I figured out the solution for me anyhow. I have only had this problem for the last few days since changing my WPA2 password.

My solution was to do the following;

1. Disconnect from my network.

2. Delete the keychain for my Airport Express from my Keychain Access App found in the Utility folder.

3. Reconnect to my network and enter the password and save to keychain.

4. Delete and re-enter my network as the only preferred network in System Preferences under network settings. ( I don't think step 4 is necessary.)

All fixed! Hope this helps!!

Hello, I thought I'd add my experience with this wifi issue on my 12" Powerbook. I upgraded to Leopard using a retail install disk and then did the software update to 10.5.3. With Tiger, I never had any problems using my Linksys router with WPA2 Personal security. After a clean install of Leopard and updating to 10.5.3 I had lots of problems connecting to my router - all with the 'connection timeout' problem.

I finally 'solved' this problem by booting my machine into 'safe mode' (holding down the shift key during reboot). This seems to have fixed my connection problems and now my Powerbook happy with the wifi connection again.

cheers,
klc

Worked for me! This has been driving me freakin' nuts, and NOTHING I tried would fix it. Until this fix. So far, so good. Holding my breath . . . . .

I believe I have solved this problem on my new MacBook Pro running 10.5.3. Took 2 steps:

1. Goto System Preferences/Sharing and rename the 'Computer Name' to something that does not include any spaces (eg MacBookPro); and

2. Do a SMC restart (see http://support.apple.com/kb/HT1411?viewlocale=en_US)

This has completely resolved the dropping connections to my wireless router problem.

Just got a mbp 15 " recently. Today I put in 4 gigs of ram. When I turned the machine back on, it would not recognize my (non-airport) wireless signal, though it did recognize three signals from other house nearby! Turning the machine off, removing the battery, etc. actually worked to restore the connection. Why...I haven't the slightest idea.

I have been reading about all of these problems here and elsewhere. My problem was with at Netgear Wireless N Gigabit router and my Macbook Pro. I have no trouble with my Macbook Air, but the Pro would always get a self-assigned IP.

Here is what I did that seems to have fixed it for me:

Go into the Router setup and setup an access list. This is to add a layer of security to your network so that only computers whose MAC Address (not Mac as in Apple, but MAC as in your ethernet network ID--you can get this from your airport setting in network preferences under Advanced). I decided to try adding both of my computers to this list. Oddly enough, BOTH computer addresses were seen by the router during this process (before I had applied these settings), so the router DID see the Macbook Pro. Once I had added both of those addresses to the network and hit apply, the Macbook Pro INSTANTLY found an IP address from the router.

I've only had this working for an hour, so I can't say it is a permanent fix, but it did work for me so far.

Further testing revealed that this did not solve the problem afterall. Lost my IP address again within the hour. Sorry for the false hope!

I have had my MBP since March and only in the last couple of weeks have been having this problem.

Well yesterday I got so frustrated with it dropping connection (note: this was not happening at all with my Powerbook) I tried to make some to the Airport Utility settings and ended up screwing everything up, network and remote Airport.

After resetting both base stations and starting over creating a whole new network, I am happy to report that I have not lost connection once. It has been connected over 14 hours now with no problems. Even sleep does not cause ill effects.

I have no idea why this worked (not a techy) but Yay!!!

If I have a problem later I will post.

P.S. I never had a dropped connection while at the office (windows based network) or any other network away from home.

Just bought a MacBook Pro and am trying to connect to the internet through our wireless router. Our other laptops (pc) have no problem connecting. We have Comcast cable. When we try to connect with Airport it says "no IP address". It finds our Linksys router but cannot connect. It wants WEP password. How do I find the password???
