Modem settings

[loopyloo]

Playing with some computer settings and had this happen.
My internet connection is as per the diagram.
The downstairs box is an older Telstra modem set up as a router.
I went to have a look at the Telstra modem settings using the downstairs computer, and when I entered its address (eg 1.2.3.4 format) I got "Problem loading page : Connection has timed out".
Why can't I get to its settings now ?

example of how i would do it

upstairs modem = 192.168.1.254 255.255.255.0 with dhcp enabled

downstairs = set its ip as 192.168.1.1 255.255.255.0 with dhcp DISABLED

to check downstairs enter 192.168.1.1

you want any ap - router to be on the same ip and subnet range as the main modem-router that is supplying the dhcp

so anything plugged in downstairs will get its ip from upstairs and the same with anything connecting via wireless

Loopy, i can only talk re cable 100/2, but reading a Whirlpool post they said that your config was causing problems and recommended
Modem Router be used as a modem only (eg 192.168.100.1), wireless switched off and in Bridging mode, Router connected to lan out let to wan input (eg 192.168.1.1)
Downstairs as is (eg 192.168.2.1) Lan to Wan. The router they are recommending is the N7000 from MSY for about $200 if your budget can carry it

Diavalo might have an opinion if this is over the top

On the downstairs "router" make sure that one port on the Upstairs modem is connected to one port (port 1,2,3, or 4). Don't worry about using bridge mode or anything, you should be able to see the downstairs modem as just another device wired as all other devices.
