Cannot ping on wireless lan

[fi_leo]

I just reinstalled my windows xp thinking that it will solve the problem but it didn't.

I've 4 laptops on wireless LAN. the router is wrt350n using wep key. I cannot ping the other computers on lan however they can ping me. I tried disabling the firewall but even after that it didn't work i've allow echo request in firewall too. I don't have any other firewall installed. Can somebody help me over this?

Thanks.

How about firewalls on the other computers? They can ping you but can they ping other computers on the network as well? Specifically the ones you cannot ping.

Yes they're able to ping. All computers have basic windows firewall nothing else. They're able to ping me. Even the router can ping me.

Usually when windows firewall is enabled, it denys ping requests.... It has nothing to do with the router firewall.....
