I don't mean to hijack the thread but my parents have a desktop with a router Asus NT or RT 10 and while my fathers computer gets wireless no problem my mothers tablet can't seem to get a good signal on the other side of the house (same floor).
Are you saying just make a new wireless network is all there is too it ?
Thanks
That is exactly what a "wireless access point (WAP)" like the WN604 is. That's what it's for, and that's exactly what it does.
You connect it via wired to your primary router, it functions as a "switch", and it radiates its own second wireless network from around itself. Any devices connecting wirelessly to the WAP are actually "relayed on" back to the primary router, so that the assigned IP address for these wireless devices are actually assigned by the primary router. If you looked at "attached devices" in the primary router, in addition to devices connected wired/wireless to the primary router you'd also see all the devices connecting wirelessly through the WAP.
Furthermore, the WAP also includes a few more wired ethernet ports of its own. So it's doubling as a "wired switch" as well. So in addition to the wireless devices connecting through the second WiFi network of the WAP, you can also have devices connected wired to the ethernet ports of the WAP... and those connections too are relayed on back to the primary router. Again, these wired connected devices to the WAP are seen as "attached devices" by the primary router.
So the WAP is really a transparent switch, that provides both wired relay connection back to the primary router as well as a second wireless network local to it that provides wireless relay connection through the WAP back to the primary router.
Transparent. It's both a wired switch, as well as a second wireless network switch providing far distant wireless connectivity. All IP addresses are assigned by your primary router.
You just connect one of its wired ports to the router at the other end of the house (1) via ethernet cable if it exists, or (2) through "ethernet over powerline" adapters if that's the only option, or (3) through "ethernet over coax" adapters if you have a nearby unused coax cable (say from an old cable TV setup in that room, which has the other end of the coax nearby your primary router or near an ethernet connection to the primary router). As long as you can connect the WAP to the primary router via some wired arrangement, the WAP now provides its own wired/wireless "switch" access point around itself.
Again, the WAP is NOT a second router. It is a wired/wireless "switch", serving simply as a relay connection for devices connected wired/wireless to the WAP and then passing those connections on to the primary router for IP address assignment and "attached devices" management.
