My server hang while other networked computer ping it!

[Schmike]

Calling Out to ALL Networking experts, Please help.

Here's the scenario..
I have 3 computers networked together by a Linksys router. All wireless connections, DHCP assigned IP. They used to be able to ping each other and shared files over the network until one day Computer A crashes and I re-install all application on Computer A.

Everything is working fine for Computer B and C as they can still see each other including Computer A. The 3 of them are still able to share files over the network. However, Coomputer A is giving me lots of headaches.

I cant ping Computer B & C using A. They all has the same range ip and subnet mask. However, Computer A can see B & C and can share their files and vice-versa. When I attempt to ping Computer A's ip from either B or C, the former hang and never recover.

I have tried to change my PCI Wifi-G card but doesn't work. I have also tried plugging cable directly into router but fail.
The only difference in Computer A between now and before crash is that I'm using 2 harddisk to do RAID-1 (mirroring) NOW. Previously there isn't any RAID being applied.

I wonder if RAID is the cause of my problem.

Please advice,
Desperate Schmike

You’re certain that it’s not that particular port on the Linksys router? Network latency should have nothing to do with your hard disk array.

With all connections being wireless?
