Internet connectivity on my desktop (debian jessie) seems to constantly fall away. I had a direct ethernet connection, in which case I had internet around 95% of the time, however I'm on wifi right now, and seem to have internet around 1% of the time. I don't actually lose the connection. I vaguely remember finding out my desktop uses the same gate as my modem(?), but didn't find out how to change that and ended up forgetting about it because the ethernet worked mostly well. Internet on my other devices works as expected.
I use a Realtek RTL8188EE Wireless Network Adapter Turning off IPv6 didn't work
