Installation went great, but now the internet doesn't work
I just installed Snow Leopard, and everything went great. New features are awesome, no complications, except that my internet doesn't work. The Airport turns on, and the network can connect (with full bars), but every time I try to use the internet, it doesn't load. Mail, Safari, Software Update, nothing.
The network (ATT DSL on a Time Capsule with built-in Airport Extreme) works fine, as I can connect easily on my laptop. The only thing I've changed is Snow Leopard.
Does anyone know how to tell Snow Leopard that yes, I really do have internet on this network?
I've also tried a lot of your ideas here... Nothing worked until I tried to use OpenDNS as DNS server... I've got an MBP late 2008 and a netgear router.
Local DNS servers works fine before upgrade to SL and on other computers (win)
But OpenDNS servers get my computer slower response than my local internet providers DNS servers...
Hello,
I upgraded last weekend, and found exactly same issues: couldn't connect to wireless router. I had just configured a new password on router, and thought that might be causing problems. However, I booted from backup image of 10.5.8 on external drive, and of course, worked perfectly.
I rebooted on 10.6, problem returned. Updated to 10.6.1, still same.
Then I checked my keychain (/username/library/kechains/login.keychain). I noticed that the keychain entry for my wifi router was not in my 10.6 keychain, so I copied the old login.keychain from the 10.5.8 ext. backup disk to the 10.6 file,overwriting the 10.6 version, and it connected straight away.
The connection has not been 100% though, and has dropped out for no apparrent reason once or twice, and i've had to go through the network diagnostics a few times to connect after booting.
Hope this is useful to someone
I upgraded to a new MacBook Pro running 10.6.1 a couple of weeks ago, and all has been great except wireless. The Airport Extreme that worked so well with 10.5.8 kept dropping me on 10.6. No one in the office had trouble; I was the only one with Snow Leopard. I tried all the remedies I found in this thread and others (reset PRAM, create new location, reset DNS cache, delete SystemConfiguration folder, etc.) but none fixed the problem for more than a few minutes.
After 45 minutes on the phone with AppleCare this afternoon, all looks good. They had me do a hard reset of the Extreme, and then reconfigure it using Airport Utility on the new Mac. The explanation was that the older Extremes didn't know how to talk to 10.6 properly, and that the 10.5.8 Airport Utility didn't know how to fix them.
If you aren't comfortable playing with hardware, then you may not want to try this -- contact Apple and have them help you. But if you're feeling bold, this may work for you.
The situation was as follows:
- I had been experiencing connection failures with less than 50% uptime. Sometimes couldn't find airport, sometimes connection timeouts, sometimes looked to be fine but couldn't connect with the network.
At the time of the call:
- Airport icon on the right side of menu bar showed five strong bars
- Network panel in System Preferences said I was connected to our local wireless network
- Airport Utility app said it didn't see any wireless devices
The reset process that led to the cure:
- make sure you have your passwords for the Airport Extreme recorded as this sequence will wipe its configuration
- powered off the cable modem and left it unplugged temporarily (make sure lights are off in case of battery backup)
- used a paperclip to press and hold the tiny reset button on the back of the Extreme until the light on the front of the Extreme flashed fast amber
- plugged the cable modem back in
- from the Mac running 10.6.1, fired up Airport Utility. You should soon see a generic Airport Extreme icon whose name starts with "Apple". Configure it. Do not restore the old settings. Note that the first name and password it asks for are the admin name/password for the Extreme, not to be confused with the network name/password.
- Configure a new network and assign it name/password. Use WPA/WPA2 Personal security.
At this point my MacBook was happily connected ... and has been stable for an hour which is longer than it had been in a week. Hope this is helpful.
Just bought my first Mac ever and I have to say I'm close to returning it, the wireless is nigh on unusuable... My 5 year old PC laptop gets 5mb downloads, this brand new Macbook Pro gets 64k, it took me 2 hours to download quicksilver....I've tried everything, new profile, open DNS, reboot etc nothing works. Of course a call to applecare results in the "well it must be your router, the mac is perfect"
IN case this might help, here's my experience (finally working wifi connectivity)
I'm on OS X 10.6.
Trying the creation of new location (under sys.pref > network) did not work. Turning off airport, modem and mac itself did not do any change (things suggested in this thread before).
However, changing my network security WEP with shared key (5 characters, ascii) to WPA-PSK/WPA2-PSK on my DLink DI-524 got everything back to normal! Note that I did do this using a "new location" that I've created before, so I'm not sure if the location creation played a role or the change of security parameters.
I'm downloading 10.6.1 now and I'm not sure if I'm gonna try getting WEP to work again 🙂.
Any resolution to this problem? I can't even get airport to recognize my express now. Same deal - working fine before snow leopard install. Talked to apple tech today and he acted like this is the first time he ever heard about this then tried to get me to pay $50 for more 'tech support'. Then told me I should buy a new express unit. This one is 10 months old and worked perfectly before snow leopard.

Note that you are entitled to 90 days of
free telephone support with the purchase of Snow Leopard itself, so there would have been no need to "upgrade" to some other support tier.
Have you tried doing a factory reset on your Express and setting it back up? Is it running the most up-to-date firmware Apple has released for it?
Resetting an AirPort Base Station or Time Capsule FAQ:
I have the same issue as anyone here with the intermittent connectivity of airport card... changed location and at least I can connect, but it still drops me.
Bottom line Apple Care people... as most of us here are loyal customers! It is way beyond me why this has not had a stern reply from support. It is an issue - it is DECEMBER, this issue has been reported in AUGEST... we want an answer and a fix.

There is an update now that should take care of this issue....
About AirPort Client Update 2009-002
This update is recommended for all Macintosh computers running Mac OS X Snow Leopard 10.6.2 and includes fixes for the following:
Inability to turn AirPort on or off in some cases after upgrading from Mac OS X Leopard
An occasional loss of network connection when using Wake on Demand
Inability to create a computer-to-computer network, or share the Internet connection on some MacBook, MacBook Pro, and Mac mini computers
I took delivery of my machine on Thursday. First problems with this on Fridayt. I downloaded this 'fix' on 12th December. As with many other solutions, it worked for a while - but on restarting the machine the next day, I was back to 'self-assigned IP' and no access via wireless. I bought this machine for travel: that it doesn't work is a scandal. I was astonished to find so much on-line discussion devoted to this fundamental issue, and by the seeming persistent disregard by Apple. Beginning to wish I'd got the Vaio!
Apple - please get serious about this: my enthusiasm and willingness to recommend are seriously eroded. Can I say this is DOA and get my money back?
