Since few days I have an issue with one of my devices connected to TO over LAN3. I have tried to exchange ethernet cable -> issue remains. I have also tried to use a different LAN connector and then everything is working fine again. That might indicate there is either something wrong with the configuration (I have not modified any settings in last month or so) or it is a hardware problem.
Would anyone have a hint where to check/what to look for, please?
My kernel Version is 4.14.162, fw TurrisOS 4.0.5 ab9d1bf / LuCI branch (git-20.016.50399-e1df28d)
