Computer problems...

[ruthabagah]

Your PC is loosing the ip address somehow. Might also be a problem with the router, assigning IP adresses out of range or a bad DHCP assignment. You may want to try to configure the router to assign a fixed IP address using the pc's MAC address.

Found an article:

Generally (for IPV4), the system used is called "DHCP", and works, broadly, as follows.

• The router runs a "DHCP Server", which has a table with IP's which can be used.
• Each computer makes a DHCP request, which is basically a packet (with its MAC address) sent on the network saying "What IP can I have ?"
• The router looks at the packet received and says here is your IP address, gateway, DNS server [and anything else]
• The computer then configures itself.

The MAC address can be used by the DHCP server table to make sure the machine gets the same IP address, if available each time.
