yes that works -- here's how
- connect cable from existing router#1 to the LAN side of router#2
this will make router#1 the controller of all IP addresses AND allow sharing between all system regardless of which router they connect to.
- configure router#2
this is done with a cable connection to it. Use the routers default ip address in your browser and supply the default user/pwd
- disable DHCP service in this router
- set router#2 address to be just like router#1 but change the last digit to 250
- set the SSID to be similar to the existing router (eg add a number to its name)
- change the channel number to be different from router#1
- (temporarily) disable encryption
- save the settings which will restart the router and drop this connection
you can disconnect the cable from router#2
Turn off (or disconnect) all systems from both routers.
power off router#2, wait 30 seconds and then restart it
At this point router#1 will be at xxx.yyy.zzz.1 and router#2 at xxx.yyy.zzz.250
Connect to either router (wired or otherwise) and you should be able to
(run->cmd) enter
ping xxx.yyy.zzz.1
ping xxx.yyy.zzz.250
Your connected system will have an address seen by
ipconfig /all
Once you can connect to both routers, you should go back to the configuration (in
both with a cabled connection) and enable encryption.
Make your life simple, set both routers to the same type of encryption (in this order of preference)
{WPA2,WPA} and use the same passphrase for both.
you really should also change the ADMIN login (on both)
save the settings and disconnect the cable.
Print/File sharing is managed elsewhere.
