I just bought a 1T HDD and reloaded Win8.1 and ubuntu 13.04 and than updated to 13.10 never had this problem before I bought a new HDD had same OS's except I used 13.04 version.
It started as soon as I put on 13.04 it was really bad took 5 hrs to update to 13.10 due to disconnects and was hoping the upgrade would fix said issue but did not sadly. I use a USB to get wifi, NetGear
Wireless-N USB Adaptor works fine in Win8.
How to fix this issue ?
