Defrag
I thought defragmenting the computer was for the speed of the computer,not internet, but if you almost dont have any space left on your hardrive,it is smart to do a derfag.If you have plenty of mb or Gb of free space, i dont think its nessesary to a defrag.
I had a couple of troubles with my connection, it always got disconnected, and needs to reconnect, i have to reconnect like every 5 min, that is ignoing, did i write this right? (Ignoing)
Codetel sucks, hope they will get some fiberoptic cables here soon.
