If a neighboring cell is highlighted in red, there is a risk that the router may repeatedly
switch between the neighboring cell and the primary cell. This can affect the performance of the
router. To prevent this, re-orient the antenna or use a directional antenna.
The next section of this window displays historical information about the quality
of the cellular WAN connection during each logging period. The router has standard intervals
such as the previous 24 hours and last week and also includes information one user-defined
