can i link 2 wifi routers to extend the wifi area in my home and outside instead of the main router and a signal extender. i want to use the 1st router netgear wpn824 in the basement office where the cable modem is.. then i keep that cpu connected to LAN1, and wireless for that side of house. Now, can i connect from LAN 2,3,or 4,from router 1 into the other wireless router at other end of house on another floor and plug it into the port where the modem would usually plug into? I'm hoping this extends the wifi signal to the other side of the house. I'm not good with these things at all, so is this asking for a lot of trouble or is it easier than i think???? since the extender connects to wifi router in same way, whats the difference? theyre the same price anyway, might as well have extra ports at other end as well

You should be able to do that . You will have to turn off the dhcp function on the 2nd router , you do not want to have 2 dhcp servers running on the subnet . Consult your router doc on how to do that .

I don;t think so...
The wireless router needs a wired input, namely the WAN port is where the signal comes in...then it sends it out on the wireless transmitter...

A wireless router does not have the ability to recieve wireless signals...

There are repeaters available...Linksys has a couple of models that work well...they are designed to do what you need...

the input for the second wireless router was coming from the lan output of the first wireless router and into the wan of the second...through the rj45 connector

Yes you can set up two wireless router like. I've done it myself. Here are some pointers you might find useful.

The first router is set up normally. Run a cable from on of the ports to the second router.

The second router is slightly more complex.
1) The cable must go into one of the LAN ports, NOT the WAN/UPLINK port.
2) This router needs a STATIC IP, gateway is the address of the first router. This helps with any address conflicts.
3) DCHP should be turned off on the second router

Next check that both routers have the same WiFi settings: same channel, same encryption, same SSID, etc.

Hope this works, and if you have any more questions I'll try to help.

Sorry, missed the second part of your post.

Two routers: you can put the second wireless network anywhere you want, as long as you ccan still run a cable to it.

Router + extender: the extender must be within range of the router, or it will be useless.

Personally I would go with the two routers. Running cables is a bit of a hassle, but wired networks beat wireless ones hands down for ease of use, reliability and speed.

As a response to an ealier post, yes wlan routers can receive from computers and other wlan routers, if they weren't able to receive from wirless sources they would be useless for networking which requires data input/output. Also, you can bridge 2 wlan routers wirelessly if the firmware of the routers support it, all you need is the mac address of the main router and the transmission settings on the second router to be the same as the first(channel,security,mixed b/g/possibly n), and possibly depending on your slave router, disable dhcp functions. This would be much better than having a huge ethernet cable going through your house
