imric Posted August 9, 2005 Share Posted August 9, 2005 Ok, cat5 cable has a maximum length of 100M (well, just under) so that would be why you are having trouble. Degradation occurs after 100M so this would explain the unusual behaviour.You'll need a repeater or a repeating device to extend the range. Or move the 3rd switch within 100M of the 2nd.

el_rob3 Posted August 9, 2005 Author Share Posted August 9, 2005 OK but it was very good before short timeand cat5e can connect upto 150 M and more depend on its type(or company).why my prob is all night only? Link to comment Share on other sites More sharing options...
imric Posted August 9, 2005 Share Posted August 9, 2005 Degradation occurs after 100M so this would explain the unusual behaviour.I would try moving the 3rd switch within 100M of the 2nd (or place a repeating device about half way between), this way you can test to see if it still has problems at night.If the problems still occur then you will know it is not the cabling between the two points.
