Thinking about what I may have done or started doing recently that coincides with the timeframe when this started to happen, this comes to my mind: I have started using a USB-to-ethernet adapter and connecting to the LAN via ethernet cable (my laptop doesn't have a builtin ethernet port), whereas previously I would only use WiFi. Of course that could be just a coincidence, but is there any logs that I can watch to see if there's anything suspicious of being related? (of course I can go back to using wifi for a while but it will take much longer to establish a correlation if there is, and potentially even longer to rule it out if there isn't)
