First of all thanks for the great work yo do.

I'm moving to a new house, it's not my house its one that I rent.

I need to create a isolate from the rest of the house a new network. I can't use ethernet, to join the routers o use plc (electric installatión it's not good).

Let me show you I think that will work for me.

Connect a "router 2" has a client of main router. And the isolate "network 2" of the rest of the home network, all equipment needs to be accesible between themselves and internet but invisible of the main network.

In the wiki a see the option "MASQUERADE NAT". This option will work ????

Did you recoment one router for this? Existis any router with two independet wifi card one for conet and another for serve? I not sure tha is necesary or will imrove cuality.

thanks and sorry for my bad English.

Not all wifi-routers can act both as a client and AP on a single band wifi router/card. And if it can and you use a single band both for connection to upstream wifi router and local wifi clients, then you will get at most half the throughput between the internet and local wifi clients.

I know TP link wdr4300 works in this type of scenario since I have used one myself. But my Hame MPR-A2 can't be used since it can't be a client and AP at the same time.

This is your basic routed client. The default configuration of the firewall will prevent anyone on the downstairs network from accessing your devices.

Either ath9k chips or MediaTek can run a client and an AP on the same radio.  Choice of a model depends a lot on if the ISP is fast cable / fiber, and if you need extra memory to run VPNs etc on the router.

Can I connect a ralink USB Dongle to router that have usb port with fully fucionallity?

The only reason to do that is if you were far away from the AP that is supplying Internet, and you need a directional antenna such as a dish on the USB radio to reach it.  Generally it is not necessary or desirable to have two radios on the same band, you can run two interfaces on one radio.

Or if you have a router with unsupported or poorly supported radio chips, yes you can put a different one on USB.  But you may not have all the options with a USB radio versus a good internal one.  The bandwidth of the USB2 bus is a bottleneck.

First Thanks!

do you know more Router than can work in this scenario?

Thanks to you too!

If I need to buy one router I prefer one than have enough memory for future setups o create VPN's or use ACL's

Mediatek = ralink?
