i don't know why but when i do clean install then start downloading software with cli, my internet disconnects and wont start unless i reboot.
i tried pppoeconf to setit up, then use command pon etc to reconnect but to no avail.

You are probably a victim of a TCP regression in the stock 2.6.27 kernel, where some slight-broken hardware fails to follow the RFC's and flakes out with valid but different TCP option orders. The Ubuntu bug report is here (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/264019); they have released a new kernel which fixes this. Your workaround to limp along with the connection surviving to download the update is
sudo sysctl -w net.ipv4.tcp_timestamps=0

i figured it out. copying some code for apt pasted twice, i wasn't paying attention, so i removed the second line of code and it works flawlessly now.
