** Option number two (If your Westell modem combo had only one RJ-45 LAN port) **
Since your modem combo has at least two RJ-45 LAN ports, this is only for your info.
#1 Your Linksys router has a built in switch.
#2 Make sure that you have a hub or switch that is not included in a router.
Please note, In your case: Since your modem combo has at least two LAN ports, no seperate hub/switch is required - so you can safely ingore this step and the steps that talk about a hub or switch that is not included in a router.
#3 Make sure that your hub or switch that is not included in a router is only connected to a power supply.
#4 Make sure your computer has a wired NIC.
#5 Make sure you know how to manually setup a Static IP on your computer.
#6 Disconnect the Linksys router from the Westell, at the Linksys router - end.
#7 Connect the end of the wire that you disconnected from the Linksys router to the uplink port of the device at step 3.
#8 Connect another wire to the Linksys router's WAN port (The port that you disconnected at step 6).
#9 The end of the wire goes to any other port of the device at step 3 but not the uplink port or the port right next to it.
#10 Disconnect the ethernet wire that is connected to your Linksys that connects to your computer (at the Linksys end).
#11 Setup a Static IP on the NIC that you disconnected at step 10 with-in the same subnet as the Modem combo.
a) You only need the IP Address and the Subnet Mask (No Default Gateway/DNS Settings).
b) If the computer is picky (it will not let you setup a Static IP without a Default Gateway and DNS), just enter in the LAN IP of the modem combo to get it to be **** up.
#12 That wire that is connected to your computer that you disconnected at the last step, you connect to any other port of the device at step 3 but not the uplink port or the port right next to it OR to the port that is use by the WAN port of Linksys router.
#13 Tada, You can access the modem combo.
#14 But you can't access the Internet at the same time
#15 To access the Internet too:
a) Your computer must have at least two NICs and at least one has to be a wired NIC.
b) The Linksys router's LAN IP can't be with-in the same subnet as the modem combo.
c) You must know how to release and renew the IP Address on your computer, as need be.
d) You must know which NIC to setup the Static IP on.
e) You must get an ethernet wire if you have a wireless connection to the Linksys router.
