I have been reading other threads and trying suggested steps but nothing seems to work for me. 50% of time the internet works fine, sometimes it slows down sometimes there is no connection at all. The most common problem seems to be "IPv6 connectivity: no network access" sometimes: IPv4 displays the same message sometimes it says "unidentified network" or "limited network access".
I've copied my computer's specs, if that is of any use. It would be great if sb would be able to help me with that.
I posted third ipconfig log for when there is absolutely no connection (at the bottom)

I copied ip config from when there is no internet at all and there is no IPv4 or 6 connectivity. I can't spot any differences

ipconfig /allwhen the connection is working fine, and save the output. Run it again when the connection is completely broken, and save the output again. Post them both here as an addition to your question. (Not just as a comment; only edits will bump your post.)
