I have a Linksys Wireless N router with 4 ports. The cable modem comes in through the basement and as a result the wireless signal doesn't reach upstairs very well. All 4 ports on the router are taken.

Can I use a spare Linksys Wireless G router daisy chained on the Wireless N router? I can sacrifice one port on the Wireless N to plug in the Wireless G like, leaving me with the following setup:

  • Cable Modem --> Wireless N WAN

  • Wireless N Outgoing Port --> Wireless G Wan

  • Wireless G ---> Upstairs Wi-Fi and 4 extra ports.

As set up, when I connect to the WiFi through the Wireless G router, I have limited network connectivity and can't connect to the greater Internet through it. How can I use the Wireless G router, connected to the cable modem through the N router, in a way that allows for ful network connectivity, maximizes wireless range and LAN ports?

This should work, what IP ranges are you using on each network? –  Chris S Apr 28 '11 at 22:48
    
Forgive me for the noobishness, but 192.168.1.1-255 (i guess?) –  Justin Amberson Apr 28 '11 at 23:23

You could do something like the following:

  1. config AP-N with SSID-N and IP range 0-127
  2. config AP-G with SSID-G and IP range 128-255
  3. flip AP-G 'backwards' and connect them by what is normally the client side of the AP
  4. point all devices at AP-N for the gateway

This gives to two SSIDs with non-overlapping IP ranges that are still technically on the same subnet (assuming that you use a /24 netmask). It also avoids the double NAT.

You need to turn off the DHCP server on the second router.

You can certainly do this, but "nested" NAT could make port forwarding ridiculously stupid. It will also increase your overall error/retransmit rate and introduce latency.

Make room on the cable modem. Consider getting a workgroup switch.
