I have 2 Raspberry Pis, a 4B and a 5. The RPi 5 is set up to access Windows 10 network shares, works on wireless and all is well. The 4B is a different ballgame. I have just downloaded and installed 12.02 to a USB flash drive, the SD card no longer working, and it all installed no problem. I then install the AMBER skin as it has better functionality for me. First problem is I get INVALID PASSWORD when setting up wireless so I can't do it. There is nothing wrong with my password. Secondly, I cannot access Windows shares until WS-Discovery is active. Unfortunately this is buried away under the basic settings and off by default. Having turned it on, SMB begins to function and I can see my network. I set up all the shared folders I need and check they all work normally and all is good. However, following a restart, there is no access to any shares - NO ROUTE TO HOST error. Well there was a route to host when I set it up and the screen that comes up in place showing various shares allows me to access the shares, suggesting there is a route to host. I then deleted everything and set it all up again using IP addresses and that all went to plan. 20 minutes later and without a restart I get the same error - NO ROUTE TO HOST.
There is clearly a route to host as I can access it in other ways, just not via the dashboard. My RPi 5 is rock solid stable with the same settings.
I know how to use Kodi but am not a technical person so please, nothing complicated. I checked 20 pages of threads without success before submitting this.
