I have about 50m between switches. When using Cat6 I could not get a connecting between switches but when I use Cat 5E I get a connection. The switches are D-Link DGS-1210-10P switches. Why do the Cat6 which is suppose to be superior to Cat 5 not getting a connection. What do I do wrong?

There is no reason I can think of, other than you had a bad connection on one end of the Cat6 cable.
