have cable modem connected 1 machine (the 1 using)
problem many times internet detects different network ip (169..) , not let me access internet not happens in linux on windows. think can fix problem formating , installing linux os manually imputing cable account # when asks me if want dhcp set automatically. yet still continues go of unexpectedly. tried setting ip,mask,gateway, manually , no internet access still.
know if can change dhcp server within ubuntu (so dont have reinstall every time.)
