use great care. Afterwards check the quality with a cable tester to avoid
transmission problems.

Information
Since a very large selection of inexpensive Ethernet cables is available
in various lengths, it is easier and quicker to buy Ethernet cables
instead of making them yourself. If you do purchase Ethernet cables,
make sure that they are of CAT5e quality.
