Connectivity, Including Web Access to My LQ Unit is Intermittent, Even Though I Am Accessing It from Within The Same LAN.

The most probable cause for this is that an IP conflict exists. In this case, the IP address used by the LQ unit is already in use by another device within your LAN. The quickest and easiest way to check if this is the problem is to change the LQ unit’s IP address to an address that is known to be available and observe if connectivity to the unit is once again consistent.
