Hi Praveen,
i am guessing that you have a supernet on the LAN. I checked the config and saw the following;
Host_Name=MagnaQuestGF
Device_Name=MagnaQuestGF
Ipv4_address=172.16.8.4
Ipv4_subnet_mask=255.255.248.0
IPv4_default_gateway=172.16.9.1
IPv4_Primary_DNS=172.16.9.1
would it be possbible to put up a simple, even 'windows paint' diagram of the network setup, IP addresses and masks.
I am guessing that the PC hosts are in one network and the wireless clients might be in another network, hence they can't 'talk' to each other.
Can you also mention the model of brand and model of the router you are using ?
it would be interesting to also see the network mask given by DHCP to the PC hosts on the LAN.
Sorry for this extra hassle, but adding a picture can be most descriptive.
