During the past days, I've been having connection problems, suddenly the pages are inaccessible, IM is disconnected, and file transfers drop to 0. I swear these problems use a timetable, because during the afternoon, everything is rock solid, but at night or in the mornings, it's a nightmare. I have to punch my ISP, but first I want to fix this particular problem, and see if it's connected somehow.
The thing is that the other day, while I suffered one of the first disconnections, I went to see the status of the connection, and I encountered this:
I went like crazy, because clearly something was not right there. First, the entry for the TCP/IP protocol is nowhere to be found; second, the dialog is not showing which Ethernet port is providing the connection; third, I can't uncheck any of the entries (and I unchecked the first two when I installed Windows). I thought it was because of the disconnection, but no, it stays the same when things go back to normal. Clearly, there is a connection, otherwise I could not be posting this, and everything is working as usual.
I tried to install the protocol, but I get an error box: "Can't find the file". What file? There is no prompt to search for one, and putting the installation CD in the drive does not get me anywhere. I tried to configure the hardware from that dialog as well, but I can't solve anything like that. I searched Google, and there lots of results, but no solution, since everyone recommends what I've already tried (including resetting the TCP/IP protocol per
this Microsoft article), and the people with these problems can't solve them after applying the fixes as well.
I can't remember the last time that dialog showed what it should, but I did not see anything wrong in the computer that might suggest something is at work (no viruses, trojans or anything similar). I wonder if maybe I broke something in the registry, or some tweak or change in the system caused this. Any ideas?
