Multiple routers from 1 DSL line?

Sounds like you know what you're doing already... I would strongly favor your option (B). Wireless repeaters do work, and have their place. But each re-broadcast sucks up wireless bandwidth, and introduces latency.

Since you've already got Cat 5 Ethernet cable in the house, you may as well take advantage of it. Put access points (or routers configured as access points) on each floor, and use the house cabling to home run back to the main router (your LinkSys Wireless-N Gigabit router). That's the only one that will actually function as a router: the others will be access points. So you'll have a star configuration.

Do all the DHCP assignments on the main router. You should be able to run this network under one SSID. No problem running this on your single DSL line: the Quest modem will only see the WAN port to your LinkSys router.

By the way: are you in a technology major at school? This project is worthy of class credit. Take some signal strength measurements before and after, draw some diagrams, maybe put together a Powerpoint presentation.

Good luck, and have fun. I'm serious about getting class credit. (And it was a pleasure reading a well-written question, too.)

You could buy the antenna extension cable, this will allow you to expand the coverage of your router. Some of the new Linksys have the antenna non-removable, so you only have the next option (I guess you could do this without buying the extension wire). Find a copper coil and wrap it around one of the antennas (or the router case) and make your own antenna (do this to both antennas if you have them and if you want). The whole idea is to take the antenna for reception to most places in the house. For coil, you can buy it at any RadioShack, or if you have coaxial cable (RG type) strip its core wire -that's what you need.

i think of the cable is a HUB or Kat cable...i think of. nicely you should use this cable on a DSL modem to connect distinctive instruments. as an occasion I unquestionably have a DSL modem and with that one modem I unquestionably have my front room computing device with internet get entry to, my computing device, and my PS2. in case you will locate one those cords and a router (for the telephone jack) for the numerous cables which you will use, you may desire to be squared away.

If you are hard wiring your new WirelessN router into your other router, I would recommend turning off the routing function of one or the other. Turn off NAT, DHCP, DNS, Firewall, everything on one of them. If you have a modem that is a modem/router combo, those are usually pretty crapp and I would recommend disabling that one and making it just a modem and running everything through the new router.

If you are having trouble with wireless reception around your house you may find it easier to use HomePlug connections.

They are not very expensive, very easy to install (just plug in) and are very reliable.
