1. The network control function of the 8×8 video matrix had failed and was reconfigured to use RS-232 serial control instead.

3. Replaced the Araknis router with a Ubiquiti router, reset all wireless access points, and successfully adopted all APs into the new network.
4. Replaced the in-ceiling single-point stereo speakers in the master bathroom and the master bedroom balcony.
5. After the router upgrade, the Control4 system was reconfigured and recommissioned to ensure stable and reliable operation.
