When I first turn the Chromebook on, it will connect to my preferred network, but then say that it is connected but no network is available. I can sometimes connect and it work long enough to log in, just for it to stop passing traffic in the middle of trying to use it. This happens with OS v 103 and 104. I have a Chromebook 11 G6 EE that works fine running OS v 97, 102, and 103. I did open crosh when I logged in, and attempted to ping anything and was unable to even ping anything in my local network. It's like it forgets how to pass traffic, occasionally it will start working again for a short time and then forget again. Any suggestions would be greatly appreciated. This is happening with several G8's in our district.
