I have a wireless router 150M Wireless Lite N Router Model No. TL-WR740N / TL-WR740ND. Normally, when I'm connected to the local network using eth0 I can ping other machines by issuing ping name. When I'm connected through wifi I have to issue ping name.domain.com. The machine is only visible in intranet. How to achieve the same behavior with wifi?

The second problem is, that I can not connect to some external sites through wifi but through eth everything is ok. I guess that is related to some port forwarding, but I'm not sure. How can I resolve this issue?

EDIT: I'm using Linux Mint.
