Hi, I am using a Macbook Pro and a Time Capsule 802.11n wireless router. Every hour, the connections, so I go into network diagnostics, type my WPA password, and then a minute later, it works perfectly! I tried setting my WPA key time out to every 10 years, but the problem still occurs. It used to work fine, until I upgraded to 10.5.3 and 10.5.4. Is there any way to disable the WPA key timeout, or fix this problem?
