I used Belkin Cat5e cable with Belkin RJ-45 jacks to make patch cables. Cable length is less than 50 feet. I used a MOD test to make sure the pairs matched, but could not get the cable to run faster than 10Mbps. I used a manufactured cable to test the link between the same devices (switch and laptop) and was able to connect at 100 Mbps. I checked the specs of the cable I purchased and confirmed that it was capable of 100Mbps (Cat5 UTP). One thing that puzzled me was that on the box it said the cable was ideal for patch panel to patch panel connections, could that be the problem? Does anyone have an idea why this is happening?
