Maybe. If you're experiencing connectivity problems you should confirm the following before you change the default IP address:
1. Make sure the Westell and Linksys set up correctly as per the FAQ shown here for wired routers and here for wireless.
2. Make sure you are running the newest firmware from the Linksys Download Website.

If you are still experiencing problems change the default IP from the standard 192.168.1.1 to 10.10.10.1 and save the settings. You may want/have to restart the Westell and PCs after the changes.

Reminder: Access the Linksys interface after the change will be via 10.10.10.1 (not 192.168.1.1).
