In one embodiment, a diagnostic device determines signal strengths of two antennas of a multi-antenna device. When the signal strength of each of the two antennas is unacceptable, the diagnostic device provides a recommendation to adjust each of the two antennas. Alternatively, when the signal strength of a first antenna of the two antennas is unacceptable while the signal strength of a second antenna of the two antennas is acceptable, the diagnostic device provides a recommendation to adjust the first antenna. However, when the signal strength of each of the two antennas is acceptable, but a difference between the signal strength of a first antenna and a second antenna of the two antennas is greater than a threshold, then the diagnostic device determines a weaker antenna with weaker signal strength between the first antenna and the second antenna, and provides a recommendation to adjust the weaker antenna.

Optimizing multi-antenna device configuration

In one embodiment, a device, having a first and a second network interface, detects a switchover by the first network interface from using a preferred wireless access standard to access a carrier network to using a second wireless access standard to access the carrier network. The device identifies when the preferred wireless access standard is again available from the carrier network using the second network interface and causes the first network interface to switch to using the preferred wireless access standard, based on identification by the second network interface that the preferred wireless access standard is again available from the carrier network.
