RM521F-GL randomly disconnects and sometimes re connects other times have to power cycle

Im using my RM module on a Mcuzone m.2 to rj45 with the rtl chip at 2.5gbe, sometimes it works for weeks and other few hours and it would loose connection i believ i cant do much trouble shooting since im using simple admin on it but seems as if the module itself disconnects. any one have this issue?

Dear @D_G
Do your device have the enough power supply?
What is your current firmware?
