So I recently installed Ubuntu on an old laptop of mine. Every time that i connect the ubuntu laptop to my network it brings the entire network down. Wireless or wired.
My router is a buffalo xtreme n with DD_WRT on it. The ubuntu laptop actually connects but after going online for a few minutes the entire network goes down and the router hands out invalid 169 addresses. I have to unplug my router and restart it to bring things back.
I am not sure what the problem could be. I feel like it is collisions bringing the network down but the laptop is configured for DHCP.
