There is 2 computers here, 1 is running Debian 6 and one - Windows XP. They are both connected via Wifi but cannot ping each other.
But, when one is connected via a wired connection, I can ping the wired one from the wireless one. And once I ping it (but not before!), pinging from the wired to the wireless also works.
So Why are the computers not seeing each other? Is there a way to correct this and make the network work when both are connected wirelessly?

When both are on the wireless network, do they have the same subnet mask? – None – 2012-01-16T04:38:25.353
@Randolph West Yes, they do. – Abbafei – 2012-01-16T04:50:39.220
can you post interface ip and routes from both machines and router ip/mask as well? – daya – 2012-01-16T04:59:33.230
I take it you've tried disabling any firewalls on the Windows side? – Amos M. Carpenter – 2012-01-16T05:00:21.507
@aaamos yes. still did not ping afterwards. – Abbafei – 2012-01-16T05:17:38.160
@Abafei Are you pinging them by their machine name or IP (ipconfig/ifconfig)? – Amos M. Carpenter – 2012-01-16T05:21:01.813
