Connection Timeout Error for WEP security I'm connecting my MacBook Pro to a router which uses WEP security. It shows a Connection Timeout error every half an hour. The security level of the router can't be changed, since its a common router. Other Mac systems are having no problems with it.

So far I've tried removing the network from the System Preferences/Network panel and restarting the router and the computer, with no luck. What should I do next?
Different devices use different wireless chipsets. Although most should be compatible sometimes they don't work well together.

Did you try to update the router's firmware? A newer one might correct some glitches.
