What you’re describing sounds like wireless bridging or repeating. A few issues with that include:
1) Repeating is typically done by Access Points, not the routers you described.
2) The routers you’re using may not support the “wirless bridge” or “wireless repeater” functions, thus referring back to #1
3) Repeating wireless signal effectively cuts your wireless throughput in half for each WAP-to-WAP connections, so this could potentially make your connections worse.
Lastly, if your router keeps dying on you, either upgrade the firmware and reconfigure it, or replace it with a more stable device…
Using two Linksys wireless routers I managed to daisy chain them to allow wireless devices to access the Web. Router 1 is on floor 1 and Router 2 is on floor 2, same building.
Router 1 is connected to the ISP cable modem and gets a dynamically asigned Internet IP from some ISP router. DHCP is on. IP on the LAN is 192.168.1.1. Router 2 has its Internet port connected to one of the Router 1 Ethernet ports; IP is 192.168.1.254 and gtwy is 192.168.1.1. DHCP Is also on. DNS’s on both routers are the same.
They work perfectly well. Devices attached to wireless1on floor 1 and to wireless 2 on floor 2, navigate the web perfectly well.
