    Hello, I have a pretty new SR Macbook (2.2ghz model) purchased in November. I'm currently sharing a wireless router with my hallmate and it seems like my Macbook randomly disconnects and loses connection with it. This is strange because it doesn't happen with any of my wireless G devices (Wii, PS3, or friend's older Dell notebook). Is this possibly caused because my airport is configured to 802.11n? Does anyone know a remedy for this? i.e. changing settings or downloading wireless configuration programs for mac? Thanks.

    What kind of router is it? Is it an N router operating in mixed G/N mode, or is it an 802.11g router? If the latter, the fact that the Macbook has 802.11n is irrelevant.

    Some things you might check...

    - See how long your DHCP lease is set to last, and bump up the time perhaps. This is in the network settings on your Mac.

    - If there are any devices that are not using DHCP to get their LAN IP address, make sure that you have not set up in such a way that they try to steal an IP that DHCP tries to lease out (so that your Macbook tries to get an IP and is assigned one that is already in use).

    Thanks your your reply. My hallmate's router is G/N. I can't find specifics about how long the DHCP is set to last...all I see is that there is a "Renew DHCP Lease" button. Also, I'm unsure about the IP's, but is there something else I can input as mine to avoid conflicting with other devices? Sorry, I know very little about networking.

    This has been happening lately with my TiBook. It's really weird. It just randomly loses the connection...
