Hi, F25 is deprecated. You should upgrade to F27 at least. The current stable version of Fedora is 28. Besides that, did you check is not a problem from your provider? Time ago I had a lot of packet dropping and after weeks kicking everything I found out it was my ISP's fault. Another thing I would check is hardware issues. Hope this helps.
