If your PC is freezing regularly, and you are on PPPoE, your computer may be looking around for a DHCP server that does not exist. Check the following: (windows)

Open control panel
· Open Network neighborhood
· Look for the first entry in the scroll box marked TCP/IP -> , that is associated with the hardware Ethernet card (ignore dialup, and VPN type bindings).
· Select "TCP/IP-> Name of NIC
· Select it and press properties
· Select IP address from the tab
· Is Obtain IP address automatically checked? If so, change that to Specify an IP address and enter 192.168.1.10, and 255.255.255.0, into IP address and subnet mask fields respectively.
· Click OK and OK, and the computer will build a driver information database and will require a reboot for the changes to take effect.
This assignment of a harmless local IP address to the TCP/IP settings bound (connected) to your network adapter will stop the in-built DHCP services from waking up every 10 minutes to look for a DHCP server so that it can "fill in the blanks". This should solve the freezing problem.
