- Added signal graphs for RSRP, RSRQ, and SINR - Added ethernet connection details - Added memory usage details - Added ping graph Known bug: Signal graphs may sometimes show inaccurate values. It seems to be a fetching error but Ill try to find the real root cause as soon as possible Co-Authored-By: Russel Yasol <73575327+dr-dolomite@users.noreply.github.com>
