I have a mesh node that has been on the air for just over 2 years. Its mounted at the top of a 250' tower and fed with 300 feet of shielded UV rated Ethernet cable, Starting about a month ago I noticed its performance bandwidth is way down and when worked hard it reboots. Doing a "WiFi Scan" it reboots all most every time. The signal levels from the surrounding mesh nodes all report the same as the day this node was installed and SNR is the same, I replaced the power injector with a new one and that made not change.
