Long Term WiFi Issues

Hi all,
I am having a strange issue when trying to establish and stay connected to a WiFi connection for extended periods of time, I am using my microPC as a host for a couple of tasks so it needs to stay powered on and remotely accessible for extended periods.

However I have noticed an odd issue that I have not been able to find an acceptable solution for. After the PC has been on and connected to the network for upwards of a day (it is a little hard to track down the exact time of disconnect), the network connection will be lost and unable to be restored.

Using the correct PW will attempt to connect for a period before returning "Something has changed since you last connected". I have not been able to find any reference to this response anywhere (although maybe my google-fu is just weak). So any ideas on how to resolve the problem or possible reasons for this issue?

I am 90% certain that it is the PC rather then the router as I am still able to connect to the router with other devices and they operate as expected. The problem can be solved by restarting the computer which I have been doing on a 24hr schedule to try and avoid this issue. But if there was another solution then I would be quite interested to find it.


TLDR: After connected to WiFi network for long period disconnects and presents with "changed since last connected message. Can be fixed by restart, is there another solution?

Try another WiFi adapter and see. Mine is stable as a rock:
