airport disconnects every so often

sometimes the time varies, its usually 10-30 minutes, it just stops working and i have to manually restart it to get it working again, its really annoying me, and i know its not the connection because my ps3 works fine without DCs.

same here

did you ever find a solution to this?
I am having the same issue, oddly it happens much more frequently when older macs attach wirelessly. If just PC's connect it doesn't seem to go down and if its just my new macbook it goes down but maybe once a day at most.
This was not an issue when first setup and no changes have been made to the router config.
