Hello,
I noticed that I could fix the issue by manually reconnecting to wifi. Apparently Kobo disconnects you from the wifi while reading after a certain time period. I managed to fix this problem always forcing the wifi to be on. I followed the guidance
here and added the following lines to the bottom of my Kobo eReader.conf.
[DeveloperSettings]
ForceWifiOn=true
Hope that helps. Can also maybe play around with the MaxWifiTimeout setting but not sure if that is working.
