Linksys router e2000 incompatible network cable france

[annpatd]

Hello,
I am trying to connect my Linksys E2000 router to my French Sagem modem but the connection is not compatible. Can I buy a cable which is compatible with the connection on a French modem

disconnect the modem from the router.

log into the router and change the LAN IP to 192.168.5.1

the modem might be trying to assign a IP of 192.168.1.xxx which would conflict with the LAN IP of the router which by default is 192.168.1.1
