I was working on a friend's 100 mbps Fast Ethernet network. One of the
40' lines we had ran suddenly quit working. So we replaced the cable and
put new connectors on and it worked. Except it was pinging about 45%
successful and 0% if you used a larger packet (4K).
By about 1 am, we were desperate. I wound up a couple feet of cable in
my hands making a small 4" coil. Suddenly packets were flying once
again. So we taped the cable, let go of it and once again, pings were
unsuccessful. So we took a donut looking metal piece and wrapped the
cable around it in a coil fashion. The rate rose to about 75%
successful. Good enough!!!
There was another line which had been run right next to the original
cable. Although it worked perfectly, we tried disconnecting it and only
running one cable at a time. This had no effect.
Any ideas on why this happened ????
No transmitters were being used at the time. Any ideaS???
