Why can't I access email with my Cisco Linksys WRT300N?

If you cannot access your email or the web, or you are getting corrupted data from the Internet while using a Cisco Network Router, the Maximum Transmission Unit (MTU) setting may need adjustment. The default MTU is 1500, but for most DSL users, it is recommended to use MTU 1492.
