I have two wifi+ethernet routers, one somewhat older ASUS RT-N11, the other a new TP-Link TL-WR941ND. The computers on our home network all support "n" wifi, except for one old Dell laptop that my wife refuses to abandon, but wants it to use wifi. My understanding is that having this machine sharing a wifi network with the others will slow everybody down to "g" speeds.
How can I configure the routers so that each can have its own wifi network (one exclusively for the older machine), but all machines can talk to one another, with no ip address collisions?
Thanks and regards,
