Router not assigning IP

Hello

You do not provide a great deal of information (the router make or model, the type of connection for each computer, etc.) so the possibilities are many. Here are a few:

If all three of your computers are connecting to the router (configuring the network connection) using DHCP, is the router set up to provide three IP addresses?

Is the DHCP server on the router enabled?

Is your router configured to use WPA on wireless connections? If it is, and your Linux box uses a wireless connection, does it support WPA?

These are just a few shots in the dark, but I hope they help. If not, please post back with better information and we will continue to try to help.

If you are more interested in getting a stable connection for your Linux box than in discovering the cause of the issue, you could configure your Linux box to use a static IP address. With a static IP address, the Linux box will not use the DHCP server to get an address. Remember that each computer on your LAN must have its own IP address. No two computers connected to the router can have the same IP address. Since the router's DHCP server dynamically assigns IP addresses within a known range (you can find out what the range is in the router's configuration WEB page), any static IP address must reside outside the range used by the DHCP server. In oter words, if the DHCP server uses the first twenty IP addresses in the subnet (192.168.0.1 through 192.168.0.20), no static IP address can be assigned in this range. The first IP address available for static assignment would be 192.168.0.21.
