I just installed the wwdc Snow Leopard preview via ADC to test an ebay app I work on. Everything works fine, except for the network connections. WHile Airport can scan and pick up networks, it cannot connect to them. Ethernet is active, but it does not connect to the internet. I have send problem report to Apple, but I dont expect that it will resolve the problem soon. Any ideas?
Got a tip for us?

Wi-fi/Internet not working in Snow Leopard

But can you browse internet at all ?
I'd the same problem, but I could browse internet (I did set the IP address manually, if I were using DHCP, no problem at all).
Some people reported this either, try reboot your Mac and if it does not work, then reinstall the OS (just launch the installer on SL and make it go).

No Airport card installed
I have a "No Airport card installed" message when I click on the icon in the menu bar. I cannot add anything to the Network preferences. Is this what other people were having?
I'm on a Macbook 1.83 Core Duo (one of the first Intel MacBooks ever sold).

Re-install I can. Just adding the AirPort from Network Preferences (what MikhailT suggested) doesn't work, as it's not there.
I have the same model of macbook with DonSqueak
and suffered from the same situation.
In System Profiler there is no airport hardware found....
I'm going to try a clean install tomorrow and see if that helps (although I doubt it). Will keep you posted.
Ok, waiting for your good news
Haha, as expected, no good news. Did a clean install (clean as in oleophobic screen after wiping with a nice dry cloth) and nothing changed. I guess the Wifi in the old MacBooks just didn't make it into this particular build (10A380).
If nobody else has any ideas, I guess I’ll just have to wait for the next build.
Cheers, dsq.
Snow Leopard Wi Fi Problems
When I installed SL, initially my Wi Fi worked, but when I brought my MacBook Pro home, I could not join my wireless network, though it recognized it. I knew it must of been SL since my wife's MB saw the internet just fine.
I went into System Preferences/Network and changed the location from Automatic to Untitled with the same location choices. This worked for me, though I am uncomfortable with having my Automatic locations not working. I am hoping for a speedy patch. This solution was posted by an IT blogger.

Wireless is working fine for me on my MacBook Air running Snow Leopard.
I actually had a similar problem, though, a couple upgrades back. The issue was Apple's digital signature on a couple files (configd, mDNSresponder, and nmblookup I think) had been corrupted - you can check it with /usr/bin/codesign. If the signature isn't valid, it'll show up as an "adhoc signature". If it's valid, it'll say something like "Apple Corporation".
The solution for me was to find an uncorrupted version of the files on one of my Time Machine backups and overwrite the corrupted ones.

My MBP (2.53) is having problems with wifi after snow leopard, after sleep or first boot up it connects to my network showing full reception, and will not receive or send data. To get it to work i just have to turn airport off and back on, it will auto connect to my network and away i go.
Was planing a fresh install due to several problems, mainly mail never being able to quit or force quit, hanging on shut down till i hold the power button down, and when minimising windows and i pop the dock up at the same it suffers from a very bad graphical problem (doesn't matter which graphics card is selected).
Was hoping for Sl to fix some of this but so far mail froze up on the first launch and has hung on shut down once so far with SL, now with the wifi problem sorta getting over it

Snow Leopard is taking longer to obtain IP addresses from wireless networks than Leopard did. It'll recognize the network and connect, but immediately grabs a 169 IP, and then later gets a valid IP. I can confirm this on two different MacBooks and more than one wireless network.
Snow Leopard and Wifi
I, too, was (and still) having problems with my wifi. Most of the previous posts were the same problems I was having. I tried some of the suggestions and... no help. Then I did the old "tried and true" method... reinstall the software!! Still no help. So... I said, "To heck with it, I'll just restore my computer to Leopard and wait for some other upgrade to fix the problem!"
Well, for some reason or other, I left the computer on, went downstairs, and when I came up again, my wifi was working perfectly!!! I have since noticed, over the last couple of days, that when I wake my Macbook Pro up from sleep, or turn it on from a complete shutdown, it can take anywhere from 1 minute to 15 minutes to work properly. It will usually find my network right away, but I won't be able to connect to the internet. So..................
I guess this is just a bug in Snow Leopard that "Steve" will have to fix. In the meantime, if it does't work for you, you might try just leaving it on for 15 minutes and maybe you'll have as much success as I have.
If not.... you might feel like throwing your macbook through a window, like I felt like doing!!!!
Apple...... works every time!!!! RIGHT!!!!!!

wifi problems continued!
In my last post, I said just waited awhile and the wifi connection would work.
Alas, that stopped working. Tonight, in desperation, I turned off my firewall and behold, wifi working perfectly. Not wanting to leave the firewall off, I turned it back on and... the wifi is working perfectly. Is this just a fluke or did the firewall on/off actually accomplish something?
I'll let Y'all know tomorrow!!
---------------------------------------------
Well, it's tomorrow and the firewall trick seems to work. No connection until I turn off the firewall. After I turned it off, I had to reconnect with my network, and then I turned the firewall back on. Everything is working as normal. I'll have to send something to Apple and see if they have discovered this problem. It should be a simple fix. The firewall seems to block the internet connection.
Y'all take care.

snow leopard is the problem.
I had the same problems with snow leopard,
wifi would connect, but could not browse the web,
LAN cable would only work for a few minutes than become inactive
It would crash my wifi network and stop all other computers from connecting to the web.
Problem solved by, reinstalling Leopard. I wont be using Snow Leopard until they fix this problem!!!

I got my wifi working, shorting after posting for help
Yeah! I had the same problem with being able to connect onto the network, but the internet not working.
So...
Go into Preferences > Networks, then Delete 'Airport' on the LHS by highlighting it and clicking on the (-) button, then Re-add it again.
The internet now works perfectly again!
wifi problem solved from another forum!
Hello All!
After another google search, I found an answer to the snow leopard wifi problem. The forum is http://www.mac-forums.com/forums/ and the answer turned out to be about security. I was using the "mac address" security filter to keep others from using my network. This turned out to be a bad idea for a couple of reasons. I found out that, with the right hardware or program, it's possible to spoof an address and get into the network. The writer suggested using WPA. It not only protects, but Snow Leopard seems to work perfectly now. No dropouts and it locks on every time.

Hope this helps those of us with the same problem.

I just upgraded to SL and having many of the same problems others are having when I go to other networks. For instance the coffee shop just down the street.
I've gotten the browsing back recently but still can't access mail or sign on ti IM. Anyone have a solution or run up against the same issues.?
