Simple and a little difficult ...

... Or simply difficult!
I was looking for a network connection to my 3 multimedia devices (BluRay, satellite receiver, TV). All 3 are wireless ready, but only for manufacturer-specific USB WLAN sticks for Felt in total 200th
So had to be a cheaper alternative. I run the AP in client mode, ie it connects via WiFi with our router and extends the over CAT5 to a 5-port switch on, hang on the wired the 3 devices.
So far so easy.
Difficult the whole is the fact that you can configure only one IP address. Because the DNS but must as the gateway and the gateway are in the same subnet in the same subnet as the client, the DHCP server can not be used this AP.
So assign all IP addresses manually below the AP.
Also DNS are not passed, so configure the router as a gateway and DNS. On the router the AP-client reports, of course only with a MAC address, but with 3 different IP addresses, depending on who wants just to access the Internet.

Anyway - after 3 nights I had it all then as far as running (I'm not a network specialist) and it works now not only upstream, but for example, for remote apps and downstream (except for the Panasonic BluRay, which is not easily found although he has perfect access to the Internet).
Really stable is also not all that, but at least it works in principle and for the price of the AP's fine.
