[Ubuntu] Local network response null

[alleks]

Hello folks, I really need your help to solve my local network issue.

I have no problem connecting from each computer, wifi or cable, to internet but when it comes to pinging local network computers and/or connect through vnc to them I get no response.

For example I do a ping 192.168.1.30 to my Work Desktop Computer and I get Destination Host Unreachable.

I can't connect to ssh or anything. Both my laptop as my desktop computer runs on Ubuntu Oneiric and I use a comtrend ar-5387un router. I will check tomorrow to see if ping responds from windows computer to windows computer.

Any suggestions will be appreciated.

Can you ping your router?

Yea, no problem pinging the router or any outside ip.

I think it has to do with a router setting. Please check your router configuration.

Router problem maybe, because I've reseted it a week ago and I have no problems since.
