I have a Cisco 881W (with a Wifi module). The network is whole Microsoft, with a DNS, DHCP, AD, etc.

When a workstation is connected on the network via ethernet cable, which is connected to a switch which is connected to the Cisco 881W, the local DNS names are resolved. For instance, when I ping "WS01", it resolves to "192.168.1.56".

But when I am connected only on the Wifi module of the Cisco 881W, I cannot ping "WS01". It does not resolve the name to an IP address. But if I ping "192.168.1.56" directly, it works.

Also, whenever I am connected to ethernet or wifi, I get the exact same DHCP configs (DNS servers, gateway, etc).

How can I make Wifi clients to resolve the DNS names?

can you ping the dns server from the wireless network? –  Paul Ackerman Aug 2 '12 at 13:46
    
Yes i can. But there is no way out of it tho. –  Jonathan Rioux Aug 2 '12 at 17:14
    
You said the DNS server is microsoft. So, your MS DHCP server is handing out IP's on the wireless network too or is the 881 running DHCP/DNS for wifi clients? –  Paul Ackerman Aug 3 '12 at 18:36
