I have a macbook pro & macbook (using OS X 10.5.7 and a wireless network with hardware as follows: (1) Linksys cable modem, (1) non-wireless Linksys router connected to (1) version 7 airport express. I also have (2) version 6 airport expresses are located in other rooms that are not connected via the extend the range mode as the longest distance from from any point to the main express (version 7 connected to Linksys route is less than 35 feet. The two version 6 expresses are used to stream music to audio systems in those two rooms.
3 days ago I purchased an Acer Aspire One. I can not get the Acer to connect wirelessly to the internet. I can get an internet connection if I connect via ethernet cable from Acer to the Linksys router. I have not tried connecting Acer via ethernet to the Airport Express. My known wireless menu on the Acer recognizes my wireless network and any where from 10-15 other wireless networks in the building in which I live. My wireless signal is the strong, all the bars are illuminated. I have a WPA/WPA2 password for the network. The Acer claims to be a WPA2. I downloaded istumbler on my Mac to look at which channels the other wireless networks in my building are operating on and switched the channel on my airports to 4 after I acertained that nobody was using either 3,4 or 5. The radio mode (not sure what this is) listed for my network is 802.11n (802.11b/g compatible)
Here's what happens: after logging onto my network with the Acer, typing in the network key and confirming it and hitting start I get a message that the Acer is attempting to connect to network. This is as far as I get before the process times out about 20 minutes later and my wireless networks disappears from the menu list altogether. My Macs continue to stay connected to my network however. In order to get my wireless network to reappear on the Acer known netowrk list I usually have to restart the computer as the refresh commands works sometimes and not at others.
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. Good luck.
