View Full Version : [ubuntu] Please help : Ubuntu 11.04 disappears from network

October 13th, 2011, 10:25 PM
Hi all
I am new to this forum and hope i am posting in the correct section.
Network setup :
Router - billion 7300n (DHCP enabled - range)
Ubuntu 11.04 desktop connected wireless to router on static ip
Windows 7 desktop connected via cable to router with DHCP
Windows 7 laptop connected wireless to router with DHCP

Ubuntu disappears from network after some time after being booted(not always the same amount of time)
Windows cannot ping ubuntu or connect via xrdp form either of the machines.
The windows machines can both ping each other.
Net view also return a error after ubuntu disappears.
I am able to browse the internet on the ubuntu macchine even when it disappers from network.
After endless searching on google decided to reinstall ubuntu and problem still persists.

Something I discovered is that if i ping one of the windows machines and then immediately ping ubuntu from that windows machine, the ping is successful. And then after a couple of seconds it starts to fail again.

I am a novice user of ubuntu any help would be appreciated
Thanks in advance
