Problem with Router

Imported from my original Blogspot archive (2007–2010). Posts are preserved as originally written, including language, formatting, and mistakes.

Today I repared 2 problems on the Internet connection.

First, the problem was, when I shared the internet connection type PPPoE by a router, could only access some Web sites, such as Google, but can not be accessed elsewhere. This problem was resolved by the end modifying the value MTU of the router to 1480 (default 1498).

Then came another problem, some computers have speed of 2.4 mbps that is normal, and others are accessed by only 1.2 mbps, half of the connection. This problem was resolved modifying the value of the TTL, 64 to 128.
