Wifi Keeps Disconnecting/Reconnecting

[iCheetah]

My wife's 2011 13" MB Pro keeps disconnecting from wifi for about 5 minutes, then reconnects for about 5 minutes. It's been doing this continuously for the past 5 hours. My 2011 17" MB Pro nor my 2007 iMac has experienced any disconnections.

I run Lion and my wife runs Snow Leopard. My connection has been strong and constant all day, but hers keeps losing connection. Any ideas?

Thanks,
Jason

you should try updating, yeah. i'm assuming you tried restarting already?

Yes, we have tried restarting and checking for updates, but the problem doesn't seem to be going away. I looked through the network settings and everything is set up correctly. Is it possible that between the three computers, hers is just receiving a weaker signal than mine?

very possibly, unless they are exactly the same computer. i know that there was some big fuss over the early 2011 (?) ones getting better wifi signal due to bigger/more antennas, but I wouldn't know since it's my first mac. haha

Try resetting and reconfiguring the router.
