try reseating the wireless card or airport card. if that doesnt work. turn off your wireless router and your macbook. leave off for 10 mins then turn on the router first then macbook. try to connect and see if that fixes the problem.
Had the same problem. What i did was in the Airport Configuration program goto "Airport" then to "Wireless" and then to "Wirelesee options" In this menu deselect "Use wide channels". Also i decreased the power of the 5.0 Ghz transmission, because i don't use it yet. But i think the "Wide channels" is the reason of the problem. It is a bit weird thoug, on my Airports Guest acount with no password and incryption, the Acer One loged on perfectly, but on my private network with WPA2 it did not. Aparantly the Guest network does not use "Wide Channels"
Hope this helps, but take care, maybe the menu's are called differendly because i had to translate them from Dutch.
Have you checked your system preferences, network settings? You have to tell the mac to use airport or ethernet. It may be setup to use the hard wire and not airport. You should see a link to turn on airport in the upper right corner of your screen. I think you can turn airport on there.
You need to check your network card software your problem may lay there. I've seen this problem many times in the passed. I will install a wireless network card or software on someones computer and two days later it will not connect everything looks fine. No matter what I do it will not connect. Remove net software for the card or on board wireless reinstall and boom it works fine.
routers may need reset or configured off the internet or the start up cd. I take this a wireless router hooked to internet gateway. don't know not enough information you may need to tell me a little more. first try install of net-card software then set you working router to unsecure no pass word need see if you connect then change it to you wpa password protected.
Using the Airport utility on your macbook (located in your Utilities folder) will tell you what the conflict is.....most likely you have DHCP issue or the network is at the incorrect setting. The wizard in the utility will tell you what you should fix.
First of all... Unplug the modem, unplug the Airport (WiFi router) and turn off the Airport connectivity in your MacBook.
After 5 full minutes... Plug in the modem.
Wait 2 full minutes... Plug in the Airport.
Wait 1 full minute... Turn on the Airport connectivity in your MacBook.
After all of that...
If you're still not back up and running and you're using an Apple Airport, open the Applications folder, open Utilities, open Airport Utility.
If you're using any other type of WiFi router, use the Network Diagnostics button that should show up in the web browser window when you try to go to any website.
