Airlink LS300 is affecting Clients Network

I am after installing a Airlink LS300 and uploaded Config templete from Inductive Automation website but unit is affecting clients network and prevents network from working properly. Is there additional settings on the LS300 that need to be disabled ?

How exactly is it affecting your network? Is it configured to act as a DHCP server?

Have you looked at the setup documentation found here

When unit is added to network it prevents users from accessing other servers in the building and also prevents them receiving mail. I uploaded template from inductive automation site and I also checked setting against the SierraWirelessL300 Setup document. The DHCP is disabled.

Have you made sure to set the Primary Gateway option to Disabled?

I will check that setting when I’m back on clients site.
